Q. I Have a wireless network setup, but there is a point where the wireless network get interference from somewhere that causing very slow network connections despite that Windows say that the signal strength is excellent, even radios or cellphones are acting up in that area.
Is there anything i can use to detect what it is that can cause this?

A. The easiest way is to use a Spectrum Analyzer. Used to be they were very expensive and only used by those who professionally work with Wifi but there are some units out now that anyone can use and afford. Wi-Spy is one of those available http://www.thinkgeek.com/gadgets/electronic/c240/
Metageeks also have several units that give a complete band view even some advanced units that are very very good . http://www.metageek.net/
In some cases a program like NetStumbler is all that is needed to find interfering AP's within range. That will give you a list of channels and SSIDs and strength of the AP's within range.
http://stumbler.net/ its just software that works with compatible wifi cards. This isn't as complete as a full spectrum scan as it won't show phones, baby room monitors, cameras etc that may be on the same channels.

How can I stop my cordless phone from interfering with my wireless router?
Q. I have 2.4 ghz spread spectrum cordless phone that autoselects the clearest channel everytime you use the phone and there is no way to change the channel manually. I also have a linksys 2.4 ghz wireless router. Using the cordless phone renders my wifi useless 9 times out of 10. I have tried to change the routers wireless channel (possible values are 1-11 I think) but that did not solve the problem. Does anyone know what I can do to prevent this interference?
A. Each device uses the same frequency band (as do garage door openers, baby monitors, Web cams, ....).
You can change frequency bands for one or the other. Use a 5Mhz phone, or a 5MHz band WiFi gear (802.11a).
Reduce the relative signal strength seen by the 802.11b/g stuff you've got. Move the phone to the other end of the house. Move the laptop (or whatever) closer, leaving the phone in the same place, ... Add an antenna (probably a corner reflector (chicken wire may be a perfectly sensible material) for the rubber ducky type of antenna design most commonly seen) to both ends of the WiFi link (you may not have to physically crack open the radios at either end, but note that this dodge increases signal strenght in one direction (and does the same to receiver sensitivity). Since both the phone handset(s) and the mobile WiFi device (a laptop, probably) is also mobile, this isn't any kind of universally adequate dodge. Find a way to reduce the phone's signal strength (probably not possible to non-techie types) unless it's possible to say, put soeme absorbing or reflecting material between the phone and the WIFi radios. An experimental bronze foil covered wall, perhaps. Ought to work well if you can keep the two radio types out of each other's effective range. May not be possible in some kinds of interior decorating environments. consult with those in charge before trying anything like this.
Another dodge ito try to arrange that the WiFi antennas are a 90 degree polarizatino difference than the phone antennas (as usually used; if you have sprawling teenagers, this may not be predictable).
Since both devices operate (or probably do) in a spread spectrum mode, each will appear to the other to be a general increase in the noise level against which they must work. Changing channels (if possible) isn't likely to be very effective. Too much noise, no radio receiver will be able to make sense of what it hears.

How can i make my wireless router faster?
Q. I have a sitecom 300n wl 368. For some reason it hovers between 14-20 mbps on wireless whilst i have a wired speed of around 90mbps. The computers/laptops all have wireless N adapters.
Any help would be appreciated.

A. Your data rate will vary. 802.11n takes into account signal strength, quality, number of spatial stream in use and a few other things to determine the data rate.
Signal strength is effected by several things. Make sure the router is placed in a location that will provide the best overall coverage of your living area. If you put it one corner of your domicile, then the opposite corner will have a weaker signal. The more stuff between the route and your device will effect the strength and quality of the signal as well. If possible have the wireless router 6-8 inches away from the nearest wall (at least) and keep other objects at least 6-8 inches away as well (I recommend at least a foot). This will minimize things like signal scattering, reflections, and absorption.
Interference is the next big thing to look for. If you are using 2.4 GHz (most are) there are a lot of things that may interfere, which will cause packet loss and decreased signal quality. Microwaves, cordless phones, and baby monitors all operate in the 2.4 GHz space. Other wireless routers in your vicinity will also cause interference if they are on the same channel. You can use software like netstumbler or Xirrus WiFi Inspector to see all the wireless routers in your area and they channels they are on. Use an unused channel (either 1, 6, or 11) that isn't in use. The channel needs to be 5 channels away from the nearest channel (if possible). So if someone is on channel 2 you should be on channel 7 at the minimum (but should use 11 by convention). If all are in use, use a channel that has the weakest signal and least used. If your devices support it you might also try 5 GHz.
Hope this helps

i have to keep telling my wireless connection to connect?
Q. I have a ZyXel Router connected to one PC and that works fine. No loss of connection.
I have a Belkin 802 11g Wireless Card in the other PC. It is this PC that keeps loosing connection.
I have done a number of things to try to stop this from happening - from enabling to disenabling Windows to find a connection; disenabling and enabling windows zero wireless configuration.
Getting fed up now!

A. The most likely cause of your problem is radio interference. A WiFi card is just a radio transceiver, and they are susceptible to interference from other devices, like cordless phones and baby monitors, and especially, from other WiFi networks. With the proliferation of WiFi access points in neighborhoods and apartment buildings, more and more people are having this kind of problem. You should also keep in mind that the clear air broadcast limit for WiFi access points as around 300 feet. If you're inside a structure, walls, furniture, and equipment limit the range even farther. I have one laptop computer that won't pick up a signal, or gets a very low signal, where my other ones work just fine. I have to move it closer to the router to get a good signal.
If you go into the configuration utility for your router - I can't be more specific than this - you should be able to change the channel it broadcasts on. That may help your problem. You won't need to do anything with the computers, since they'll find the channel on their own. If it doesn't help, try a different WiFi card. They work best when they're made by the same company as the router.
