Have you tried changing the channel on which your wifi access point operates? ________________________________________________ Stephen Bogdanski Network Support, MSU-CVM Michigan State University [log in to unmask] A227 VetMed Center Phone: (517) 353-5551 East Lansing, MI 48824 Fax: (517) 432-2937 >>> Amy Fekete <[log in to unmask]> 07/09/04 09:53AM >>> It's really irritating since the access point is sitting on top of my tv cabinet in the same room! I do know that my neighbor/daycare lady just got a wi-fi network and accesses it via cable modem. But I was having problems before that.

I use a tool called Network Stumbler, which locates access points, shows SSIDs, and graphs signal strength. It is odd that you lose signal strength at night; AM radio travels farther at night (that's why WKAR-AM goes off the air at dark) but I think this spectrum is not susceptible to that, and my guess is you have a neighbor competing for 2.4G spectrum. If it's another Wi-Fi user NetStumbler can help you find 'em. Maybe you can join their network. :-) Someone who actually knows radio theory please speak up... http://www.netstumbler.com/ /rich On Fri, 9 Jul 2004 08:29:10 -0400, Amy Fekete <[log in to unmask]> wrote: > What would you recommend for others with the same wi-fi problem that > isn't caused by a panasonic phone?
