Hi, I mentioned this as an aside recently, but thought I'd come back to it. I have an Intel Wireless Centrino 2230 providing wifi in my thinkpad. I picked the Intel option over the Broadcom chipset because I thought it'd have better Linux driver support. (I've had trouble with Broadcom chipsets in the past) Unfortunately the driver support seems broken. It happily connects to wireless network, but transfer rates max out at around 30-40 kbyte/sec. Yuck. I'm on Ubuntu's 3.11 kernel; not the absolute latest, but fairly recent. I've already tried updating the firmware (was already on latest) and various combinations of the module options: 11n_disable, bt_coex_active, swcrypto. None of these give any significant improvement. Unfortunately I can't just replace the mini-pcie card, because Lenovo lock the BIOS in modern Thinkpad's down to the particular PCI ID. If you replace the card with another, the BIOS won't boot! I doubt there's much else I can do, but thought I'd ask here just in case there's something magic I've missed when searching. Cheers, Toby
