Stable wireless with the AusPi Wireless Adapter
If you are having problems with the AusPi Wireless Adapter maintaining network connectivity over long periods of inactivity, please check the following thread for assistance.
Specifically, the fix is as follows:
After 5 minutes to 5 hours the WiFi would stop and nothing except rebooting would make it recover. I also got repeated emessages from dmesg: phy0 -> rt2x00usb_vendor_request: Error. That led me to this forum. I used the same fix as argief and a number of others.
MediaTek (Ralink) lists RT5370 in the file:
DP0_RT5572_LinuxSTA_22.214.171.124_20121022.tar.bz2 (816 kb)
and points to common/rt2870.bin (8192 bytes) as the correct bin file.
1) Replace /lib/firmware/rt2870.bin (after backing it up)
2) add a line to /etc/network/interfaces
iface wlan inet manual
insert ==> post-up iwconfig wlan0 power off
Rebooting was successful immediately and the WiFi has been stable for 48 hours running most of that time with network traffic and working during the day with 4 remote terminal windows via ssh. Thanks to everyone for this fix.
Thanks very much to John from immediate C for this fix!
