** Description changed: This has been going on for years, reported a number of times, eg. 773599, 812981 and quite some more. As far as I can see, mostly closed for lack of activity. (Though the lack of activity was not so much on the side of the reporters.) I can confirm, that two sticks that I have, two different sticks, with that same chipset, both fail in different machines, running 11.10 and now 12.04 with 3.2.0-26 kernel. I don't say that this is all. It still load the rt2x00usb , which was also considered a culprit in some reports and workarounds, and does not yet use the hwcrypt option, but the power option alone makes a difference: - $ iwconfig wlan0 | grep Power - Bit Rate=54 Mb/s Tx-Power=20 dBm - Power Management:off + Bit Rate=54 Mb/s Tx-Power=20 dBm + Power Management:off $ ping 192.168.116.200 PING 192.168.116.200 (192.168.116.200) 56(84) bytes of data. 64 bytes from 192.168.116.200: icmp_req=1 ttl=64 time=2.40 ms 64 bytes from 192.168.116.200: icmp_req=2 ttl=64 time=2.40 ms 64 bytes from 192.168.116.200: icmp_req=5 ttl=64 time=1.52 ms 64 bytes from 192.168.116.200: icmp_req=6 ttl=64 time=1.90 ms 64 bytes from 192.168.116.200: icmp_req=7 ttl=64 time=1.41 ms 64 bytes from 192.168.116.200: icmp_req=8 ttl=64 time=1.51 ms 64 bytes from 192.168.116.200: icmp_req=9 ttl=64 time=1.44 ms 64 bytes from 192.168.116.200: icmp_req=10 ttl=64 time=1.14 ms 64 bytes from 192.168.116.200: icmp_req=11 ttl=64 time=1.81 ms 64 bytes from 192.168.116.200: icmp_req=12 ttl=64 time=1.53 ms $ sudo iwconfig wlan0 power on $ iwconfig wlan0 | grep Power - Bit Rate=54 Mb/s Tx-Power=20 dBm - Power Management:on + Bit Rate=54 Mb/s Tx-Power=20 dBm + Power Management:on $ ping 192.168.116.200 PING 192.168.116.200 (192.168.116.200) 56(84) bytes of data. 64 bytes from 192.168.116.200: icmp_req=1 ttl=64 time=11.9 ms 64 bytes from 192.168.116.200: icmp_req=2 ttl=64 time=1.75 ms 64 bytes from 192.168.116.200: icmp_req=3 ttl=64 time=13.1 ms 64 bytes from 192.168.116.200: icmp_req=4 ttl=64 time=122 ms 64 bytes from 192.168.116.200: icmp_req=5 ttl=64 time=156 ms 64 bytes from 192.168.116.200: icmp_req=6 ttl=64 time=54.6 ms 64 bytes from 192.168.116.200: icmp_req=7 ttl=64 time=93.9 ms 64 bytes from 192.168.116.200: icmp_req=8 ttl=64 time=1.62 ms 64 bytes from 192.168.116.200: icmp_req=9 ttl=64 time=4.16 ms 64 bytes from 192.168.116.200: icmp_req=10 ttl=64 time=13.5 ms 64 bytes from 192.168.116.200: icmp_req=11 ttl=64 time=15.3 ms 64 bytes from 192.168.116.200: icmp_req=12 ttl=64 time=11.8 ms $ sudo iwconfig wlan0 power off $ iwconfig wlan0 | grep Power - Bit Rate=54 Mb/s Tx-Power=20 dBm - Power Management:off + Bit Rate=54 Mb/s Tx-Power=20 dBm + Power Management:off $ ping 192.168.116.200 PING 192.168.116.200 (192.168.116.200) 56(84) bytes of data. 64 bytes from 192.168.116.200: icmp_req=1 ttl=64 time=1.40 ms 64 bytes from 192.168.116.200: icmp_req=2 ttl=64 time=1.26 ms 64 bytes from 192.168.116.200: icmp_req=3 ttl=64 time=2.17 ms 64 bytes from 192.168.116.200: icmp_req=4 ttl=64 time=1.93 ms 64 bytes from 192.168.116.200: icmp_req=7 ttl=64 time=0.989 ms 64 bytes from 192.168.116.200: icmp_req=9 ttl=64 time=3.52 ms 64 bytes from 192.168.116.200: icmp_req=10 ttl=64 time=1.90 ms 64 bytes from 192.168.116.200: icmp_req=13 ttl=64 time=1.69 ms - The signal strength is relatively weak, - Link Quality=32/70 Signal level=-78 dBm + The signal strength is relatively weak, + Link Quality=32/70 Signal level=-78 dBm though the 100-s of milliseconds at times to the access point are characteristic. The ping times are in average 10 times slower with power on. Still, I don't say that this is *the* workaround. I gathered it from some other, unfortunately abandoned, bug reports with other work-arounds. Needless to say that the sticks work perfectly okay in Windows.
