Wireless dropout every few minutes

I have a Linksys SRX400 router which I have had and loved for 2 years. All of a sudden, the wireless connectivity has started dropping out for roughly 10 seconds every few minutes. This is extremely aggrivating and only occurs over wireless (rules out all ISP problems and some router problems) I was thinking it was an IP address conflict, so I set a static IP on this machine 192.168.1.125 and I still get the problem.

The following machines use the wireless netowork:
Custom built (Windows 7 RC1) (static IP)
Custom built (Windows XP)
Compaq laptop (XP)
IBM Laptop (XP)
iPod Touch 1G (OSX)

any ideas? I cannot figure out any pattern either. This even happens when only 1 computer is in use...

I have already tried different channels, and my adapter does not have power save. (All the computers have this problem, all have different adapters, and none have had any settings changed recently)

I got a WRT54GL, put Tomato on it, and now I have no problems. I guess my router just died of old age...
