All three of these will need a modified bios on a T60. I personally am very happy with the 4965agn cards, they work very well and are very inexpensive.

Intel WiFi Link 5100. Intel WiFi Link 5100/5300 WLAN controller Intel WiFi Link 5100 and 5300 WLAN controller This is a Mini-PCI Express WiFi Adapter, supported by the iwlagn driver since the 2.6.26 kernels.

The 5100 would be a good choice if you only have two antenna and you don't want to install a third, but if you do want to add a third, The 5300 is the newest of the three cards so there may have been some updates added to it, but the 4965 supports the same speeds and both support dual band and Mimo, the 5100 does not support mimo. There is an atheros based card that will work in the T60 without a bios mod. It's the only 'n' capable card that will. In my other T61 I'm using 4965agn with two antennas only, as the laptop came with older 3945abg card thus no third antenna. The third port on the 4965 is a repeater of some sort and is supposed to aid in performance to the other two, but the card itself is a two stream thus only needs two antennas to function fine. And frankly I haven't noticed any difference between using 2 and 3 antennas on that one, as before the same card was in my primary T61 that had 3 antennas.

The 5300 on the other hand is a three stream card thus needs all 3 antennas to work at its full potential. It would of course outperform the 4965 given you have wifi router that can support three streams simultaneously.

Note that the supported speeds are the maximum that could ever be achieved theoretically, but in real life the speed that you'll operate at does not come even close to that. The best of the mainstream routers right now can achieve somewhere around 60mbps on average (with about 90mbps max if laptop is very close to router and no interference, so rare case). Also all of the listed cards are full size mini PCI, but you can use half sized cards with adapter.

I'm using the latest (and greatest ) Intel Ultimate-N 6300 WiFi card, which is capable of 450 mbit with 3 channels, but I have only 2 antenna cables attached.

Currently I use it with a Linksys WRT610N router, (N-300 Mbit) on the 5 Ghz channel. This is a high-end router from 2009. During local network file transfers I've seen it hit 17 MB/sec sometimes, but usually it is around 12-14 MB/sec (96-112 Mbit). Backslashnl1 wrote.

I guess you must be in the same room with very little interference to get that high speeds over wifi.

I even had to pull some info on it to see what it usually does, and here it is. Using a 4965AGN card with third antenna in my T60 project. It's a nice improvement over the original card in all respects. Recently upgraded from a Netgear WG102 AP to a dual-band Asus RT-N66U router. Actually kept the WG102 for G clients and use the RT-N66U for N clients. Really happy with the Asus so far. Generally seeing Win7 reported (not measured) 2.4GHz link connectivity at 144Mbps a couple rooms away from the router.

The Asus traffic log shows my last nightly 2.4GHz wireless client backup to a WHS hitting 1301.46kbps (=10.2Mbps). Tempted to try the 5300 card with my setup.

I even had to pull some info on it to see what it usually does, and here it is: You're right, I installed the router (which I use as an acces point) in my living room and I'm about 4 meters away of it. Rarbg official website. Initially I installed it in the cupboard in the hall, but the reception was poor on 5 Ghz, about 2-3 bars out of 5.

I decided to reinstall my old router (Linksys WRT54GL with tomato firmware) for older network devices on the 2.4 Ghz band, and the WRT610N on the 5Ghz band with N-speed only (instead of BGN mixed). This setup is perfect for my situation. TuuS wrote: If you'd like to add a third antenna, send me you're address and I'll drop you one in the mail. You can let us know if it makes any difference. The third antenna is for Mimo, multiple in, multiple out, and should help with reception and performance, but I think the difference will be seen only in cases where your two antenna reception is strained.
