I asked for more descriptive, not less. Approximate interval and
duration in minutes. Does it coincide with meal times? Coincide
with 15 minute commercial breaks? Are you near a cafeteria full of
microwave ovens? Any TIVO boxes with wireless? Any 2.4GHz security
cameras? Any 2.4Ghz cordless mice?

It doesn't have to be yours. I could be your neighbors. Is your
wireless router perhaps sitting in a window with a good view of the
neighborhood?

90% of the wireless access points are delivered configured for channel
6. Please try channel 1 or 11. If in UK, try 14.

OK. Good card. Comes in 4 different models. Check the power save
settings on both cards. Some cards don't recover very gracefully when
the computah goes into hibrination, sleep mode, power save, or
wireless card power save (all these are different).

Assumption, the mother of all screwups.

Good clue. That's another reason why I suspect RF interference. If
both the old and new routers were mostly working, then interference
will affect them both equally.

I spend the better part of a day troubleshooting an erratic disconnect
problem. Eventually, I discovered that the wireless router was
rebooting. A little investigation uncovered a defective power strip
that was very intermittant. Check your power please.

Which program is generating that error message? That's not the common
error message delivered by Windoze XP SP2 Wireless Zero Config.
However, that's just a curiousity item. There are only 2 things I
know that can prematurely require a premature DHCP renewal without
rebooting the computer. Interference won't do it.
1. The router reboots.
2. The wireless client radio or computah goes to sleep.

The WRT54G has the uptime on the status page. You can see if there
have been any uncheduled reboots by monitoring the uptime.

Temporarily disable *ALL* the power save features in the wireless
client computah and see if that magically fixes the problem.
