USB adapter shows higher speed than Intel Centrino Wireless-N 2200 (PCIE for desktop)

EHuma — Mon, 20 Jan 2014 19:09:50 GMT

USB adapter TP-LINK TL-WN722N shows higher speed (60 Mbit\s) than Intel Centrino Wireless-N 2200 PCIE for Desktop (40 Mbit\s).

On the same PC.

Router: TP-LINK TL-WR941ND

Settings on router: DD-WRT, 40Mhz, N-Only, Auto-channel

Signel quality in both cases is near 50%

I have tried all settings for Intel adapter in Device Manager

Is the reason only in coincidence of the router and adapter manufacturer (TP-LINK)?

Router settings:

Intel

Upload is very low.

TP-LINK

If the 60 Mbps is for each of two MIMO channels the result will never be 300 Mbps, I think.

But in other utility speed is higher:

I am sorry for this issue.

While an internet speed test is not exactly a proper throughput test we can recommend latest driver version 16.7 and the recommended adapter and security settings for 802.11n.

The issue was caused bу cloning MAC adress of WAN port on router.

Forgive me, Intel.
