I have a lenovo t520 laptop with an Intel Centrino Advanced-N 6205. What's the max speed I can get from that wifi card?

On their website it states it can reach 300mbps but I'm not really sure that's true because I can only connect right now to my router at 144mbps.

If I get a TL-WR841N router (http://www.tp-link.com/en/products/details/cat-9_TL-WR841N.html) will I be able to get 300mbps between this wifi card and this router?

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. 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...

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. 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.
