For that last long while, I have been having strange vague wifi fails every few days -- my ipw2200 ad-hoc server would suddenly become very unresponsive -- instead of the usual stable 0.6ms pings, they would fluctuate wildly from a minimum of about 2ms to 10ms, even though the connection wasn't being used. More seriously/substantially, iwconfig would show the "Tx excessive retries" to be steadily increasing -- and drastically increasing with more usage -- 10-100 retries per second under heavy usage. I have tried playing with the "Retry limit" "RTS thr" and "Fragrment thr" values a bit, and with a fixed bitrate, but they didn't seem to have any significant effect -- the connection would still inevitably reach this turbulence and ultimately fail, forcing me to restart it. I don't think it's simply a noisy environment, although there are about 10 other access points around here, none of which shares my channel 1 at the moment. (There's one on 2, one on 3.) Because that wouldn't explain why the connection becomes stable and fast after I restart the wifi interface. I'm guessing it's something to do with the driver? -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
