Either the reception or the transmission of frames still causes trouble sometimes. When I force the device to use a fixed rate I can get a pretty stable connection. - 11g rates seem to work only when I'm really close to the AP (~1m) - 11b rates seem to work much better but I can also see retries sometimes. - 11n rates seem to work as well (but are not used by the default rate control algorithm yet). So, could you please try different fixed rates and see what results you get? iwconfig wlan0 rate 11M should do the trick. Replace 11M in subsequent tests with 1M or 6M or 54M to get different results. Btw. does anybody know how I can force a fixed rate without Wext? > On 2.6.34-rc* kernel I still have the same issue I noticed some times > ago: > > Apr 28 00:10:18 eagle3 kernel: [ 1359.907914] rt2800pci 0000:06:00.0: firmware: requesting rt2860.bin > Apr 28 00:10:18 eagle3 kernel: [ 1360.033584] phy1 -> rt2x00lib_request_firmware: Info - Firmware detected - version: 0.26. > Apr 28 00:10:18 eagle3 kernel: [ 1360.043280] phy1 -> rt2800pci_load_firmware: Error - PBF system register not ready. > Apr 28 00:10:18 eagle3 kernel: [ 1360.043793] phy1 -> rt2x00pci_regbusy_read: Error - Indirect register access failed: > offset=0x00007010, value=0x3dca191a Can't help you with these, sorry.
