Hello, The "netdev watchdog: mwlan0: transmit timed out" issue has hit me too. After this console message the gumstix freezes (kernel hang?). This issue appears in 3 threads still without resolution. I suggest a new Subject line for this thread above. May 14 - "Re: wifistix issue" Jun 29 - "Anti-spam filtered my wifi question" Aug 24 - "Kernel panic on setting essid" I have seen it occur in at least 2 situations: Outdoors doing a file transfer (scp 500000 byte file) over a marginal wifi link in Ad-hoc mode. This happened a few times during many file transfer tests (in warm sunlight). Indoors, room temperature, just after or during boot up when plugging in a CompactFlash memory card to the wifi board. This is an almost a reliable to produce this error. I would sure appreciate advice on this problem. By the way, the command, the 'iwconfig' command does not work correctly as it does on other linux systems. iwconfig mwlan0 essid <anything> always truncates the final character, no matter how long the requested essid is. iwconfig mwlan0 power <anything> does not change the power, it always remains at 18.

That one's been fixed in the more recent versions of the buildroot. > iwconfig mwlan0 power <anything> > does not change the power, it always remains at 18. That one's new to me -- I haven't tried changing the power setting recently, but it sure used to work. I'll take a look next week at the office. C |

Re: power Shouldn't that be txpower? power controls the power management. iwconfig --help Usage: iwconfig [interface] .. interface power {period N|timeout N|saving N|off} interface txpower {NmW|NdBm|off|auto} .. Also I think on some adaptors it will only set properly if the power level is supported. -- View this message in context: http://www.nabble.com/netdev-watchdog%3A-mwlan0%3A-transmit-timed-out-tf4541230.html#a12962874 Sent from the Gumstix mailing list archive at Nabble.com. |
