I've just bought an Acer Aspire Revo 3700 and this had very similar symptoms with a different adapter. Luckily another customer had posted about it on the vendor's website and his fix works for me. The fix is to blacklist the rt2800pci module and the rt2860sta driver seems to work quite happily without it. It looks as if rt2800pci was introduced somewhere between 2.6.32 and 2.6.34 and I experienced the crashes with 2.6.35 (Mint 10/Ubuntu 10.10) and 2.6.37 (Debian unstable), but not with 2.6.32 (Debian squeeze) which doesn't have that module. It's probably just coincidence, but I was struck by how similar the symptoms are and wondered whether these different drivers have anything in common? lspci output: 02:00.0 Network controller [0280]: RaLink RT3090 Wireless 802.11n 1T/1R PCIe [1814:3090] Subsystem: Lite-On Communications Inc Device [11ad:6622] Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- SERR- Kernel driver in use: rt2860
