I have a T41 and, as I am about to upgrade to fibre optic broadband, I want a wireless card that supports 802.11n protocol. I was about to buy a TP link TL-WL811N when I saw this review on the Amazon website.
"The product its self may be fine,the only problem is that after purchasing 3 different cards from
tp link ,belkin,d link all of which were n series cards 300mbps no of them worked on 5 different IBM think pads.
After several phone calls to the card manufactures and the a lengthy call to Lenovo,it turns out that IBM think pads
don't like the new n series 300mbps system".
Please can anybody recommend a card that I could use? Should I go for a slower card?

There are Atheros-chipped mini-PCI cards available on eBay that will do the trick, but you'll have to do the "no-1802" hack to get them to work in your T41. These have only 2 antennae and will function with that generation of ThinkPads.
That being said, I doubt that you'll get anywhere near 300Mbps, but you'll likely do better than the 54Mbps normally achieved with "g" cards.

Many thanks for this, very helpful, reply. As a total novice in this area I had never heard of the "no-1802" hack. Modifying the BIOS is something that I really would prefer to avoid!! Are there no cards on the "white list" that I can just buy to do the job? It appears to be a very strange restriction for IBM to lumber you with - and I worked for them for over 25 years!

When T4x series started rolling off the assembly line, "n" was not a standard range...
