Zadaniya po chercheniyu. The speed is negotiated between the router and the card. When you see 144 it normally means the router is running in 20mhz mode but is able to get good signal with 2 paths.

I'm running a t510 thinkpad and have just about everything working except the wireless on a Intel® Centrino® Advanced-N 6200 AGN. On another hackintosh.

This is many times done because the router has detected another router on adjacent channels and changed to 20mhz to avoid interference. This is part of the standard to share bandwidth between neighbors but you might be able to force it to 40mhz. Still that means you will then get interference. These connection speed numbers really just represent the encoding options and theoretical total bandwidth. You will never get anywhere near those rates.

Pretty much even the best nic cards and the best routers are only able to get 100m download speeds using the 802.11n on 2.4g. Abaqus 6 14 cracked. You have to go to 802.11ac and there the rates over 1g are even more of fake number, those will get maybe 200-300m It really doesn't matter as long as the rate is higher than you are buying from the ISP the ISP connection will slow you down first.
