Too much wireless network saturation cause network problems

    I am having wireless network problems. I have a WRT54G with the latest (official) firmware. I even bought the high gain antennas. Every day or so my wireless network craps out and neither of my devices can connect to my router. I am using an intel pro 2200 wireless card on my laptop, and a d-link usb wireless G on my desktop. I have tried every single tweaking option including over 2 hours on with linksys tech support.

    I hypothosize that with so many different wireless networks in range, there is too much interference and it causes my network to crap out. Also , I have very high signal speed degradation only about 15 feet from the router.

    Can anyone confirm this? Does anyone know an answer? Any help will be appreciated. Who wants to go back to wired.

    Based on personal experience, saturation can DEFINITELY be a problem -- especially if everything is set to the same (or overlapping) channels or you have other wireless devices (cordless phones) thrown into the mix.

    I have also found that the age of the wireless access points/routers and the brands do make a difference. Routers made by the same companies tend to "play better with others" of the same brands.

    I have also had lots of issues with older routers (Linksys-B, 3 years old) not being able to deal with having other G/pre-N routers nearby -- even though they supposedly try to use the spectrum in compatible manners, some of the older units just can't deal with it.

    I recently had to replace a router (the same Linksys 802.11b unit) when it went completely wonky after two neighbors added new WAP's (one of which appears to be a WRT54G running at near maximum transmit power) and the other is a new Netgear "pre-N" unit. I'm not really sure which one was the straw that broke the camels back, but in that environment the poor little Linksys runs for about 30 seconds and the the wireless section just shuts down. It still functions as a normal router but no wireless.

    After moving the same router to a different location for testing (one with no other access points nearby) it still works like a champ.

    Change the antennas for directional antennas. This will cut down on interference. Try HyperWRT for a nice signal boost, and the latest versions contain the benefits of the latest Linksys code. I like the panel antennas and the Hawking +15 corner reflect. This type of directional antenna physically limits the coverage area, yet it also limits interference by exactly the same factor.

    You might also be able to "punch through" on channels 3 or 9.
