Title: only setup 40 Mhz for 2,4 Ghz
Post by: fjknat on December 30, 2016, 08:46:02 PM
Hi,

My router wifi is 842L and wifi adapter card on PC is 548 (N300).
PC used Win 10.
I set 11n and Chanel with = Auto 20/40 Mhz but my PC just show speed < 150Mbps (20 Mhz).  :'(
I want only setup Channel Width = 40 Mhz for 2,4 Ghz.

Who know setting it ?

Thanks,

What is your adapter on your PC?  It might not be capable.

I had a 2016 laptop that was $300 and it only did 20 Mhz and was capped, but the wire was 1 Gb. 
My $700 2008 laptop wireless could do 300 Mbps but only 100 Mbps wired. So go figure.

So we should start with your machine details...

I used Dlink DWA-548 PCI, It support 802.11n and N300 (300 Mpbs).

Did you set the DIR842 transmission power to High?

How far is the computer from the router?  Is there any interference, or walls, or tables in between?

Which F/W of the DWA-548 are you using?   I see 3 listed.

Try using Single mode N, manual channel 11, and WPA2 Personal and AES only on the router.

It's possible that the drivers between the router and this adapter may be incompatible.
Also can you test with Windows 7 or 8 by chance? There is no offical drivers for Windows 10
