OK, I know that this isn't going to be straightforward, but I'd really like to get it working.
About 18-24 months ago, my Asus EEE 901 netbook was working fine - running Ubuntu - and I let it 'upgrade' as the update manager suggested. The wi-fi subsequently failed - and, while busy with other things, fiddled and 'hosed' the OS install. The netbook stayed in a cupboard until this weekend... when I overwrote the drives using /dev/zero - then installed a completely fresh copy of Linux Mint 12.
On the fresh install, I'm still having problems with the Wi-Fi, though everything else is fine.
With the default Linux Mint install, the first indication of a problem comes from this entry in /var/log/syslog
... [5.048933] rt2800pci 0000:01:00.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19 ... [5.048980] rt2800pci 0000:01:00.0: setting latency timer to 64 ... [5.062119] phy0 -> rt2800_init_eeprom: Error - Invalid RF chipset detected. ... [5.062134] phy0 -> rt2x00lib_probe_dev: Error failed to allocate device ... [... ] rt2800pci 0000:01:00.0: PCI INT A disabled
Following some advice found online, I blacklisted rt2800pci by entering the following into /etc/modprobe.d/rt2800.conf
blacklist rt2800pci blacklist rt2800lib
This left me with a working install - but no wi-fi support. I then set out to identify the correct driver. The relevant output from lshw is:
*-network UNCLAIMED description: Network controller product: RT2800 802.11n PCI vendor: Ralink corp physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 32 bits clock: 33MHz capabilities: bus_master cap_list configuration: latency=0 resources: memory:fbef0000-febfffff
If I then use lspci to investigate further with "lspci -vs 01:00.0"
01:00.0 Network controller: Ralink corp. RT2800 802.11n PCI Subsystem: Ralink corp. Device 2860 Physical Slot: eeepc-wifi Flags: bus master, fast devsel, latency 0, IRQ 11 Memory at febef0000 (32-bit, non-prefetchable) [size=64K] Kernel modules: rt2800pci
A little more searching online suggested that, rather than use the rt2800pci driver for a 2860 device, I needed to use the rt2860sta driver. I don't have one of those installed with the generic kernel.
I visited http://www.ralinktech.com/en/04_support/support.php?sn=501 - and downloaded "RT2860PCI/mPCI/CB/PCIe(RT2760/RT2790/RT2860/RT2890)" - and followed the instructions in README_STA.
When I used insmod to install the new driver, I got an ra0 device reported... and network-manager identified that the netbook had a wireless capability. Unfortunately, that's where things fell apart. None of the local infrastructure-mode access points were found by the network-manager... and when I tried to connect to one by explicitly giving its name... no connection was able to be established - and ifconfig gave some worrying output... The Mac address looked bogus 00:00:ff:ff:ff:ff - and thousands of 'overruns'.
So... The question: Does Linux still support the Ralink driver in my Asus EEE 901? If so, which is the correct driver to use - and how do I configure that driver?
Output of "lspci -n" (I've no idea what might be useful in this...)

If I return to the default configuration - with nothing blacklisted, and run "lsmod | grep rt", I get this:
parport_pc 32114 0 rt2800pci 18340 0 rt2800lib 48717 1 rt2800pci crc_ccitt 12595 1 rt2800lib rt2x00pci 14202 1 rt2800pci rt2x00lib 48114 3 rt2800pci,rt2800lib,rt2x00pci mac80211 272785 3 rt2800lib,rt2x00pci,rt2x00lib cfg80211 172392 2 rt2x00lib,mac80211 eeprom_93cx6 12653 1 rt2800pci parport 40930 3 parport_pc,ppdev,lp
From this I don't see any obvious conflicts - advice as to what else to look for welcome.
Even more info...
I've opted to take a screwdriver to my 901, and removed the Wi-Fi card. On the back of it, there's a label that suggests it's not a 2800 series at all - but, rather, it's an RT2700E. Perhaps, if Linux is wrongly detecting it as being a 2800 series, that's the root of my troubles?
