Question : Problem: Frequent disconnection of wireless

Hello Experts,
I have a weird issue. We have a big office and each desk has around  5-10 users. We have kept 7 Airport Extremes in  each desk respectively. Everything was fine from past 1 year until day before yesterday. Users are getting disconnected from the wireless network for few seconds and then get connected. We have a mix network of windows and mac. For windows users i can see the the wireless shows disconnected and immediately comes back and shows acquiring network address and get connected. It all happens in less than 1 minute so i couldn't get any lead to troubleshoot this. Have anybody came across this issue. I checked in some forums and found that if access points are nearby, then each one should have a difference of 5 channels from the immediate one. When checked with the airport utility all the wireless access points are set from channel 1,2 etc respectively. But if this was the issue, then i was wondering how it was working perfectly up to this time?
Is there any tools available to check this, or to see if this is caused due to an interference. Please help me as this is a serious issue.
Thanks in advance

Answer : Problem: Frequent disconnection of wireless

Multiple experts have indicated this is most likely to due interference.  There will be no magic bullet fix.  You are going to have to do some of the legwork at this point.  My recommendation is to create a WDS network via this Apple link  http://support.apple.com/kb/HT2044.  That will allow them to all communicate on the same channel.

Packet sniffing is unlikely to solve the problem.  You have a problem with interference and you have a proposed solution.  Other experts are confirming that.
