Hey!
I recently got following USB wireless dongle:
148f:3070 Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter
phy8 -> rt2x00_set_chip: Info - Chipset detected - rt: 3070, rf: 0005, rev: 0201.
The initial impression of this dongle was bad - I couldn't connect to
the local WPA/TKIP network and although initial connection to nearby WEP
network went fine, the connection dropped after less than a minute and I
couldn't reconnect anymore. This was all with firmware version 22.
Thankfully the module has 'nohwcrypto' option - with this everything
works well for a while (~10-15 minutes) but then it disconnets and
connections neither to WPA/TKIP or WEP network succeed.
This is latest Linus's kernel and relevant log (nohwcrypto):
