Very odd wireless issues with high ping times at multiple sites.
This has been a week of oddness...
Multiple sites with wifi, all have the same issue so far. High latency, ping time round trips of 3000ms plus, 70%+ packet loss, etc. Physical locations are spread from miles apart. Note that wired devices at these locations, even connected to the switch in the AP itself, work fine without issues and 38ms round trip times.
Location 1) Yesterday our Cisco AIR 1240 threw this fit... nothing would get it working correctly. Replaced with cheapo Linksys E2500 from Radio Shack... same issues. Upgraded firmware on 1240, wiped config, reconfigured and works like a champ.
Location 2) Today, separate physical location, WRT54GL loaded with DD-WRT has same issues. This is in a mill which is very dusty, and the AP has seen better days, so as I had to run into town anyways I picked up a cheapo Belkin N700... same issues with latency and packet loss.
Any ideas on just what is going on? Wirelessmon shows dropouts at roughly 1 per second. Signal strength typically around 50db. Location 2 is surrounded by nothing, not a single other AP and all channels are clear.

Replaced cables already.
Fairly sure; we are really in the middle of nowhere and have 50+ acres of our land surrounding us.

try a different port on the switch side?
are you using as wifi bridge or routor?

Yes, I've tried all the basic troubleshooting steps of changing out cables, different switches (everything from unmanaged SMC to managed Catalyst 2950).
Just an autonomous AP, hangs off from switchport to switchport.

from the AP admin page can you send pings/traceroutes?

Not sure that's a feature on the Belkin.
What was odd is that after the firmware upgrade on the Cisco 1240, which is an enterprise level AP, everything was fine. I don't typically touch consumer-level AP's, so I've just been a bit surprised that the two I've picked up in the last two days, from different sources and different manuf., exhibited the same problems. Why the Cisco 1240 had the same issue, but then worked after firmware upgrade and reconfiguration, is really beyond me.

if configuring in win 7 or vista always view in compatibly mode or use mozilla.
may have been bad code from the factory or rough shelf handling.....

Answers too basic and not understanding the complexity of the issue.
