Ubuntu: Wireless suddenly dropping with a Ralink RT2870



Question:

I have a Linksys WUSB600N v1 Dual-Band Wireless-N Network Adapter Ralink RT2870 USB dongle that worked flawlessly in 11.10. Since upgrading, I can't keep a connection for more than five minutes. The wild world of Google was unable to provide a solution, and I would rather not downgrade although that remains a possibility.

Results of syslog:

slack@slack:~$ tail /var/log/syslog  Apr 26 20:26:10 slack AptDaemon: INFO: Initializing daemon  Apr 26 20:26:10 slack AptDaemon.PackageKit: INFO: Initializing PackageKit compat layer  Apr 26 20:26:10 slack dbus[972]: [system] Successfully activated service 'org.freedesktop.PackageKit'  Apr 26 20:26:10 slack AptDaemon.PackageKit: INFO: Initializing PackageKit transaction  Apr 26 20:26:10 slack AptDaemon.Worker: INFO: Simulating trans: /org/debian/apt/transaction/aaed4e38eb3c41ad86d2bab6ca03ee7c  Apr 26 20:26:10 slack AptDaemon.Worker: INFO: Processing transaction /org/debian/apt/transaction/aaed4e38eb3c41ad86d2bab6ca03ee7c  Apr 26 20:26:12 slack dbus[972]: [system] Activating service name='com.ubuntu.SystemService' (using servicehelper)  Apr 26 20:26:12 slack dbus[972]: [system] Successfully activated service 'com.ubuntu.SystemService'  Apr 26 20:30:26 slack AptDaemon.PackageKit: INFO: Get updates()  Apr 26 20:30:27 slack AptDaemon.Worker: INFO: Finished transaction /org/debian/apt/transaction/aaed4e38eb3c41ad86d2bab6ca03ee7c  

Any suggestions?


Solution:1

My experience is that the official rt2870usb kernel driver is not reliable.

I just downloaded the 2.5.0.3 driver from ralink and compiled it. That works flawlessly.
