Model :

Hardware Version :

Firmware Version :

ISP :

So I previously had a TP link WDN 4800 and it basically had the same problems this new card is having.

I cannot use this card on 5 Ghz wifi, it's basically unusable. I get pings to my router of 200-1000 ms constantly and speeds of 1-2 mbps. Funnily enough 2.4 Ghz is fine, but that is not why I bought this card. I want AC speeds and it can't even do that.
I've searched and searched, and apparently the Windows 10 driver they provide isn't really working properly. The driver date still shows 2014. A couple of people mentioned to download the Broadcom drivers and install those, but that didn't solve the problem either. It's still just as bad.

I know it's not my router (Asus AC-66U) because my laptop with 5 Ghz AC easily gets maximum speeds. It's just this terrible card I've had for one day.

Does anyone have any suggestions? I feel this is a Windows 10/driver problem most likely though I'm not going to go through the hassle of reverting to Windows 7/8 just to verify this.

Thanks.

Hi,

I'm having the same problem with this adapter on my Windows 10 pc. 2.4 ghz Works fine but I dont bought this adapter for this...
I'm using an archer c7 ac1750 router and the t9e ac1900 adapter, my phone, my tv, my Xbox can connect to my 5ghz network, but my pc dont... Frustrating isnt it? I actually CANT see any 5ghz networks on my pc... Just 2.4 ghz...

I tested a few drivers as well and Im planning to do more tests tonight but I dont believe this issue will have a solution soon..

If I have any success on this, I let you know how I made it...
