Mediatek MT7630E 802.11bgn Wi-Fi Adapter doesn't work in 802.11n mode (N-mode), only in G-mode

[ValerVY]

Few days ago I got new HP ProBook 430 G1 notebook. OS: Windows 8.1

It have Mediatek MT7630E 802.11bgn Wi-Fi Adapter inside.

Trouble: I found that wireless adapter doesn't work in 802.11n mode (N-mode), but works well only in G-mode.

No any changes in driver settings on Advanced tab are solved problem.

I think it is a hardware bug, or (less possibly) a driver bug.

In other forums I heard that HP can replace wireless board to another, that will work well. Isn't it?

Are we talking about N-150 (2.4 ghz) or N-300 (5 ghz)? It only works in the 2.4 ghz band not 5 ghz

I go into my router config, it seems to be N-150

So, if I try to manually select Wireless Channel, it gives me CH1 - 2,412 GHz, and CH13 - 2,472 GHz

[Huffer]

Most people use one of the middle channels but 1 or 13 should work.

You incorrectly understood me. I meant, of course, all channels from the 1st to the 13th.

I solved the problem by unistalling completly  all WiFi software and the device with it's drivers from control panel.

Then downloaded last drivers from oficial Mediatek site.

In Advanced tab of the driver settings new option appeared - "802.11n direct mode".

After enabling this mode WiFi began work in N-mode well.
