I'm trying to make a wireless access point work in a small office building. The symptoms are that no matter what access point and laptop are used- it associates, then sometimes works well for a while- but usually within a minute or two stops working. It will still indicate associated, but no local resources, no Internet, etc. Any of these laptops will connect elsewhere just fine. There are 4 floors and about 6 or 8 small suites per floor. When I open up my laptop (that uses 802.11b/g) utility to look for wireless access points there are at least 4 AP's with 90 or 100% signal, and another 10 above 50%. I am sure I have the settings correct on both the laptop and the AP. And I have tried 2 different AP's that both work with my laptop, as long as it is not in this building. The other suites are using a variety of channels, but since only 1,6, and 11 do not overlap- there is obviously a ton of overlap. So, how do I tell conclusively that the issue is too much contention for any channel I use and how do I resolve it? FWIW one of the access points I can use is a cisco 1200 series that has some pretty advanced settings that may be of some use.
