WiFi Help

Internet surfing and online information exchange through e-mails have necessitated users to have easier and more convenient access. While broadbands allow for such access through a landline connection or through the use of USBs, these still pose an inconvenience and limited accessibility. The wireless network connection to the Internet, the IEEE 802.11 technology or commonly referred to as WiFi, is a preferred alternative. However, despite the advantages that WiFi offers, there are WiFi interferences that result in less than efficient connections.

Possible causes of WiFi interference

Many wireless technologies, other wireless local area networks (LANs), and electric devices cause WiFi interference. As WiFi depends on radio frequency (RF), interfering signals from other RF sources result in poor connection. Each 802.11 station only transmits packets when there is no other station transmitting. If another station happens to be sending a packet, the other stations will wait until the medium is free. In certain cases, even with RF interference, a WiFi station will automatically switch to a lower data rate, resulting in slower wireless applications. Devices that cause WiFi interference are portable phones, cordless phones, microwave ovens, Bluetooth devices (e.g., laptops and PDAs), wireless video cameras, outdoor microwave links, wireless game controllers, and fluorescent lights.

Dealing with WiFi interference issues

In order to minimize WiFi interferences, WiFi providers should undertake certain steps. Before installing a WiFi connection, know the other RF sources in the vicinity. Ensure that the area has strong wireless LAN signals. Tune access points to channels that avoid the frequencies of interfering signals. Or, deploy a WiFi connection along the 5 gigahertz band. Whenever possible, disallow or minimize the use of Bluetooth-enabled devices or microwave ovens within the area.

A WiFi user should be ready to accept that WiFi interferences can be experienced. However, the benefits of WiFi far outweighs the problems that come with it.

Many computer users are turning to WiFi because of its obvious benefits, most especially the possibility of moving around your home or office while remaining connected to your network or the Internet. Unfortunately, this ideal situation may turn out to be not so ideal because of the difficulties that are often encountered when going wireless.

Possible problems one might encounter when using WiFi

The advantage of not being tethered to the network comes with a price. One of the common problems with WiFi is the failure to connect due to obstructions and interference. Floors and walls can block the signal and create WiFi dead zones. Other possible glitches could be due to a conflict between the OS and the hardware and security problems from packet sniffers.

WiFi troubleshooting tips

If you are not getting a signal, the solution is to simply transfer to another area or you can move your WiFi antenna. If the problem persists, look for sources of interference, such as alarm systems, cordless phones, and microwave ovens. For OS problems, you will need to make sure that the system is set up to connect to the network. With regard to security, do no forget to apply the WPA patch and use this in combination with address filtering.

In conclusion, many problems may be encountered when using WiFi. However, with a little perseverance and patience, these can be remedied.

If I were to discuss or even bug everyone about WiFi help in the forums, it would always have to be about the topic of security. For one, sometimes it's not cool for me to allow other users to do some snooping on my network, especially back in LA, where the neighborhoods are pretty high-tech enough that there's a geek in every corner ready to snap at your advertised network. There are lots of solutions to this type of dilemma, though, but they have their own pros and cons.

By configuring your router to allow only access to few users, you can acquire a little bit of security, but not enough, since your own AP is still open for snoops if one of your PCs are turned off. A lot of WiFi users do away with MAC filtering, since AP won't be able to connect on a non-listed address. A great alternative is the WEP, but it takes longer to crack the encryption code if it's 64bit and not 128. Another way is to use encrypted tunnels on your wireless links - but there's a caveat to this, as it can halt your network to a slower data transfer time.

You'd be lucky to use WiFi on a rather low-tech neighborhood, as folks around you won't have the tech savvy to sniff your network data or take advantage of your WiFi access. Some WiFi users secure their networks by preventing it to get advertised, and sure this is one of the best ways. It's still very experimental though, and quite difficult to configure. The best way to find WiFi help over security is to check out the forums each time, in case someone has a particularly bright idea.

There are many WiFi Internet providers available for net users to have a fast Internet connection. Among the said providers include the T-Mobile HotSpot in the US.

T-Mobile HotSpot gives a WiFi wireless broadband Internet service in various locations, like coffee houses, music stores, and book cafes, Inn locations, hotels, print centers, and even resorts. With the use of laptop and other hand held WiFi compatible devices, one may be have access to fast Internet connection provided by T-mobile. The said Internet service provider installs various access points throughout different service locations. It transmits a wireless radio signal to an Internet user's network card. A log-in page will be viewed by the users to enter the password as well as the user name. So, once the connection is verified by T-Mobile, users can now use the Internet resources.

However, T-Mobile HotSpot is not really a secured network just like other wireless Internet service. Remember that network security may be installed using security-designed software and hardware. Although T-Mobile does have its efforts of network security, it still does not guarantee an effective secured connection. It is the responsibility of the users to provide security measures that will best suit their condition and connection needs.

The terms involved in high-tech digital devices are pretty much unintelligible to the unskilled user, but proves to be a major language evolution to those who have technical skills. Such terms are so often used in digital platforms that we sometimes get lost in the confusing jargon. Specifically with wireless internet connectivity now a possibility, these set of 3-letter words have also developed into new technical terms for equally new technical capabilities.

VLAN. This is the term which refers to virtual local area networks. In case you still don't know what it's for, then I suggest you go get a good book about wireless, mobile, or remote networking. Even include the term WLAN, or wireless local area networks, in your quest for technical knowledge. Upon doing so, you now have the capability to understand the tip which I would be discussing on the last portion of this post.

Compartmentalizing WLAN through VLAN. Congestion of wireless networks often goes along with its development. Thus, a formidable solution would be to break down a physical local area network into a number of virtual domains. With this step, your network is assured of proper management and security monitoring. With virtual network management, you arm yourself with a platform in which to decongest traffic on your wireless network.

Wireless internet connectivity is fast becoming the choice of travelers and tourists of the world. This is because wireless internet hotspots are increasing in the parts of the world where businessmen and holiday enthusiasts most frequently visit. With this, wireless VoIP is also the choice of such people for their communication needs. But what about the so-precious disk space to be conserved for those long hours of conversations on VoIP using a laptop behind a wireless internet connection? With this, some people have integrated their understanding on mobile phone call recording systems with wireless computing and communications behind VoIP. Thus, an answer to the problem at hand is provided.

You see, mobile phones have limited memory disk space. This is good if you only use your precious disk space for your entertainment endeavours, such as music listening and minor video viewing. But with the AMR and 3GPP formats, music and video entertainment, respectively, are taken one step ahead of the game. But then again, what if you use your communications equipment for recording long hours of phone conversations? Since using your mobile phone for such a task is out of the question, you then resort to using your laptop equipped with VoIP capabilities. But with mobile internet telephony, you grasp wireless internet connectivity for this purpose. Logically, you should be able to see my point by now. Yes, why not use the AMR compression format to record those important phone conversations you frequently have on your laptop and VoIP service! Then, for your phone call recording sessions while in areas wherein both dial-up and broadband internet services are lacking, using wireless internet connectivity should be your last resort. This would thus answer your mobile communication needs, more so your mobile phone conversation recording needs!

I have discussed on my last posts about the inaccessibility of wireless connectivity to most locations at the present. This would generally be something that would not be a problem in the near future, but since it is now, don't you think it would do you good to be prepared? After all, an ounce of prevention is far better than a pound of cure, which usually costs a hundred fold more than the former, don't you think? This goes as well as for modern information technology.

Thus, as I have stated to keep in mind including a dial-up modem in your laptop and prepaid dial-up internet cards in your pockets, I would also suggest getting a Bluetooth-enabled mobile phone. With this Bluetooth phone, you assure yourself of wireless connectivity anytime, anywhere! How? Read on, my friend, so as to be enlightened by Bluetooth technology and what it can do to alleviate your present information-gathering condition!

Of course, your Bluetooth-enabled mobile phone should always have functional communications services from international providers. This would assure you even more of security regarding those emergency internet connectivity situations. All you need to do is use your Bluetooth phone as the phone line in which to connect your dial-up modem. Thus, through this, your laptop is now a wireless internet communications port anytime, anywhere! Just remember to always keep a prepaid dial-up internet connection card or two if your mobile service provider doesn't offer dial-up internet services.

Last night, I pondered on the idea of being stuck in a place where wireless connectivity is virtually an impossibility. Then, if my laptop is not configured for other internet connection capabilities as well, wouldn't that leave me with absolutely no option at all for my information addiction? As I thought about it more, I realized WiFi hotspots aren't yet that extensive! So if I find myself lost and stranded in a ghost town with phone lines but no wireless connectivity nor outgoing long distance call features, wouldn't that leave my laptop useless?

This is the main reason why I got up in the morning and immediately installed a broadband modem on my laptop, which also had dial-up capabilities. This just goes to show that even high-tech communications equipment developers tend to take for granted a thing or two past functions in exchange for speed and flexibility. By doing this, I assure myself of access to most areas I frequently visit without WiFi connection capabilities. I just keep a prepaid internet card or two just in case I get caught up in a similar situation as to the one I was thinking about last night. This wouldn't cost much either, for you just need a broadband modem with dial-up capabilities and prepaid internet cards. I suggest you go and get a voice modem and VoIP service as well for those moments of panic, entrapment, hostility, and WiFi inaccessibility!

The advent of high-tech communication technologies paved the way for tons of advanced electronic gizmos, the proliferation of information as if it were on cocaine, and of course, wireless fidelity. Wireless Fidelity - WiFi is a system which incorporates internet connectivity, radio and TV broadcasting reception, multimedia messaging, and telecommunications, all in one package which is cost-effective and efficient. But, with these advancements, there are certain issues which pertain to the privacy of either individuals or corporations involved in these technologies, and fortunately, VIACK Corporation has an answer to the main problem plaguing the world in the Information Age: WiFi security through both hardware and software developments.

VIACK Corporation is a leading provider of wireless internet connectivity, and has continued to address both residential and corporate needs for security and privacy regarding wireless network connectivity. The company has come up with its own formidable solutions to the ever growing problem of privacy and security with a combination of hardware modifications, software developments, and manpower - that old and reliable power source! They offer their clients a combination of spam blockers, anti-viral applications, firewall security software, and other anti-malware programs, apart from hardware routers, proxy servers, and of course, a technical crew ready for battle 24 hours a day, 7 days a week so as to provide you with a safe and secure wireless connectivity for either your internet, communications, broadcasting, and researching needs.

Do you often get yourself stuck on issues which involve your wireless fidelity internet or media connections? Doesn't a good instructional book or digital video on wifi help ease your problems a bit, and thus give you a sense of well-being? This is where your wifi service provider's responsibilities come in - yes, we have our share of responsibilities, and they, too, aren't exempt on this long standing fact of life, but you must also remember that with great power comes even greater responsibilities, and such power to choose a wifi internet service provider, or any wifi service provider, for that matter, also comes bundled with its respective share of responsibilities?

You must know first the nature of wifi connections, the respective hardware specifications for each wifi connection, then the service available on the locations you frequently visit, and finally what you really need, plus the withstanding fact that there should always be ready technical support provided by the wifi provider of your choice to its clientele. That's right, an accessible technical support crew - most companies nowadays, specially those which are involved in internet, communications, and information services, usually provide a 24-hour 7-day-a-week technical support crew, in which all their clients have to do is call, and enlightenment would come as easy as 1-2-3. Some of these technical support services can even be accessed via e-mail, via SMS, or via snail-mail - the latter option are for those without any form of communication other than it, and it would perhaps take you about a month or so to get a reply from the technical support crew, thus your needs for reliable wifi services would long be up by then!

DeviceScape is shipping a Java-based software suite which aims at assisting corporate help desks in supporting wireless users. Wireless Operations Center, or WOC, provides a visual view of wireless infrastructure, making it easier for support staff to resolve common problems. An extensible version of OEM helps WLAN equipment vendors differentiate their products.

WOC provides a visual view of wireless infrastructure making it easier to resolve the most common help requests related to wireless access. It shows access point location, health, channels, power, signal propagation, RF coverage, interference, and proximity to rogue access points, and can summarize access point and user activity, roaming, history, and throughput. It's "time machine" feature displays "the complete state of the network at any point in the past through the present."

According to DeviceScape, WOC works with switches, routers, and servers supporting generic SNMP MIBv2 (management information base), as well as access points that include those supporting standard 802.11 MIBs, those based on DeviceScape's software stacks, Cisco Aironet access points based on IOS or VxWorks, and Proxim Orinoco access points. In addition, an extensible version of WOC is available to WLAN OEMs, including those building devices based on embedded Linux. The OEM version has a message-driven architecture, and allows device makers to differentiate their products by adding management and monitoring features such as additional Dashboard views.

Lately, I have observed that wireless networks could sometimes work slower than how they are expected to do so. In our house, for example, my brother put up a WiFi network so we can have our connections right in the comfort of our room. But, as time went by we began experiencing interferences whose causes and origins we do not know.

From time to time, I have been reminding my brother to buy a software that analyzes the spectrum of interference. I learned about this software over the Internet. It works like a dog that sniffs interferences. These interferences do not only come from other networks, say for example from our neighbors who also have WiFis, but from the home appliances as well. Devices such as cordless kitchen appliances and mobile phones contribute to the interferences.

The spectrum analyzer readily plugs-in to a PC. It reports its analysis of the interferences by presenting a graph that shows the configurations. It measures interferences in hertz so it feels like having a radio or television network. The software really helped us a lot in finding out incoming interferences and where these are coming from. I find it really convenient to use since it does not require an external antenna.

Are you in a rush in setting up a wireless network to get Internet connection to work as quickly as possible? Of course, everybody is going crazy over getting wireless, wireless in the office and wireless in homes. But are you aware of the security risks of setting up home networks that are wireless? If you're not, consider these two tips to improve your security.

First, you must change the password for default administrators. All of WiFi home networks must have an access in access points or router. In setting up this equipment, there are provided web pages that can help users to enter the account information and network address. These are protected web tools with a password and username to secure the right of the owner. But, you must remember that this provided logins are common to Internet hackers. So, you must change the password often.

Second, you must turn on the WEP/WPA Encryption. All of WiFi equipments have forms of encryption. Encryption is a kind of technology within the network that scrambles the messages or words that are sent in the wireless network. This is done to protect the messages. To function, all devices of WiFi in your LAN should share encryptions that are identical in settings. So, you need to look for a denominator that is most common to all of your devices.

By doing this, you can be sure that the wireless network is secure. Wireless security is very important to avoid any undesirable things to happen in your network. Now, you don't need to worry.

The best things in life are free. The same is true with wireless communication. Is it not best when you can freely get connected with anybody around the world?

But, at times, you may encounter some difficulties in utilizing WiFi free hotspot. There are certain things to bear in mind when it comes to fast Internet access using your wireless device. This is to ensure effective and hassle-free wireless communication.

First, when the connection is not secure, use virtual private network for your protection. Take note that the signal is not always strong and it may not be on at all times. Therefore, see to it that you are actually searching for the correct network signal, otherwise, you will not be able to access it. Do it on your own. Anticipating staff assistance may not work at all because some of them are not even aware of it. You are unwired, so it follows that you are not supposed to see a lot of plugs. In this case, always carry with you an extra battery. There are locations that do not permit you to deliver an outgoing e-mail. If this happens, you may use a web-based e-mail account. But, most importantly, do not dare to forget that it is absolutely free.

WiFi network access operates under the 802.11b specification which have three access points, namely, bridge, NAT router and NAT router +bridge. Bridge type access is the type of access that connects a WiFi network to a wired network. Communication between these two different networks work both ways.

A NAT router type, on the other hand, directs digital signal traffic from a wireless network to an Ethernet wired network but the communication is only one way. Lastly, NAT router+bridge is a type of access which combined both of the preceding types. This bridges wireless and wired networks and directs them to the Internet by using one IP address.
