I am posting this as it may help others who are looking to make use of N mode on the Intel 4965AGN wireless adapters. My T61 has one installed, and here are some things you should know:
1. 801.11n mode will not work unless you disable security entirely or use AES encryption. This means all your wireless devices must support AES with WPA-PSK. Or no security at all.
2. Supposedly, the 4965AGN will work with Wireless-N access points that have the "Connect with Intel Centrino" label. There are not many Wireless-N access points carrying that label on retailers shelves, and of course Intel does not provide a list of compatible access points either (thanks for nothing).
3. I did a speed test comparison between a Linksys WRK54G and a Buffalo Wireless-N Nfiniti model WZR2-G300N. The download speed was approximately double that of the WRK54G - 8500 kbps on a Comcast cable setup.

N works out of the box with my new t61p connected to the new Belkin N1 Vision wireless router. 100+Mbps. Cool stuff.

Thanks for this very helpful information. I'm getting my T61 soon which will come with a 4965AGN card. I was thinking of pairing it up with a Linksys WRT150N router. However, just recently I bought a WRT54G (rev. 8) and I'm wondering whether it's worth while to upgrade to these draft-n routers. You get an increase in speed, that's good - can you comment about range/signal?
What was the model of your Wireless N router you tested with? -
Personally, I'm waiting for d-link DIR-855 router. You really want a dual-band (2.4Ghz and 5.8Ghz) router for maximum compatibility in a mixed environment (2.4Ghz) while maintaining maximum speed for 802.11n (which likely requires 5.8Ghz for channel bonding because of interference and limited channel availability in 2.4Ghz band). I think it's that "mixed" environment of n and a/b/g that the original post is referencing.

Is "Draft-N" considered beta? From what I've read, all it doesn't have is some kind of certification from a certain organization. I guess it's not official yet, so it's somewhat beta.
I recall reading that Pre-N routers provided more thoroughput than Draft-N routers - but Pre-N had compatibility issues which were somewhat resolved with Draft-N.
I want to go Draft-N more for the range/signal improvements it gives over G. I read reviews saying that you can get a signal from almost over 600 feet with Draft-N, and sometimes 1000 feet depending on the router and interference in your area. So, my assumption is that for ranges 600 feet and less, it'll be rock solid stable.
I purchased a WRT54G a week ago for $50 CAD. This week, the WRT150N is onsale for ~$60. Personally, I would never have the intention of upgrading to N; but my T61 w/ 4965AGN is coming soon and ~$10 more for N, is it worth it? -

Wait now I remember. Pre-N isn't even "N"... right?

My understanding is that "Pre-N" doesn't have an official meaning. Could mean whatever the vendor wants it to mean. Draft N should be either Draft 1.0 or Draft 2.0. Draft 2.0 is nearly a dead certainty to be firmware compatible with the final standard. Draft 1.0, from what I read by experts, *should* be upgradeable, but the vendor has to take the time and effort to do so. We should see a whole bunch of N activity with new routers this quarter. In my book, it's already a few months later than I was expecting (i.e. Fall vs Summer).
But then last year I was expecting to get my way cool Santa Rosa notebook with all the goodies (including built-in 802.11n) in April or May of this year, and here it is nearly September and I'm still waiting for my T61p to arrive! -
Hi Guys, I have a Gateway M-6817 laptop with the Intel 4965AGN wireless chip with a Netgear WNR854T. It works well with this router because it has the security options for WPA-PSK [TKIP] + WPA2-PSK [AES]. I'm assuming that when Windows reports the speed for my wireless connection is 144Mbps it's working in Wireless-N mode. It also support my Linksys WGA54G Game adpater. Thanks Blukski for posting this info...

I have 4965AGN on my X61s and works perfectly with DLink 655 - connects at 100+Mbps using WPA PSK.

1. 801.11n mode will not work unless you disable security entirely or use AES encryption. This means all your wireless devices must support AES with WPA-PSK. Or no security at all.
At first thanks you a lot for this Information. I just couldn't figure it out, why I cannot connect to my new Linksys WRT150N Router over the highspeed N Standard.
Now I changed the encryption to AES with WPA-PSK and it works. I hope some older devices will be still able to connect... -
great info, thanks
-
Thanks for the info, just bought the linksys WRT150N.
After changing the setting i had speed up to 130Mbps.
