I just replaced the IPW2200 mini-PCI card in my Thinkpad with a ral(4)-based MSI MP54G4 (MS-6833A-010) from newegg.com (dmesg snippet below). It works great so far, except the radio activity LED that used to indicate association with an access point and network activity no longer lights up at all.
Any ideas if this is just a software issue or maybe a hardware incompatibility between mini-PCI cards? Thanks. ral0 at pci1 dev 2 function 0 "Ralink RT2560" rev 0x01: irq 11, address 00:13:d3:76:35:c6 ral0: MAC/BBP RT2560 (rev 0x04), RF RT2525
