Hello!
So moderator deleting posts when something bad is being said about this adapter.
Now please tell me is this normal? https://www.speedtest.net/result/10089472207
I'm able to achieve 400 Mb/s with my other devices that is near same PC, while this TP-Link adapter able to download at this speed. My router is C7
I tried many different drivers so the question is - did someone managed to fix their wi-fi speed?
1. Have this adapter for a couple weeks already, it's been working like that since it was purchased.
2. 
3. It seems that this adapter only working on 2ghz and not 5ghz. I tried also to follow these steps for adapter to prefer 5ghz:
- Right click windows logo in lower right bar
- Choose "Device Manager"
- Expand Network adapters
- Right click the "TP-LINK 802.11ac" device and choose "Properties"
- Click the "Advanced" tap and in "Property:" find "Band Preference"
- Choose "Prefer 802.11a"
But it seems that I don't have this option in my settings. Could it be driver issue? Using official driver from TP-Link website (Windows 10 x64)
4. To be honest not sure why i need to change my router settings if all other devices connect properly to 5Ghz and reach ~400-500 Mb/s, while this adapter (which is 20cm away from other devices) manage to reach only 40 Mb/s. It's not router problem for sure. Could it be driver problem?
------------------
Update!!!! I downloaded broadcam drivers and band pref apperead in properties of the device. I changed so it could work with 5 Ghz only and now I'm getting 80 Mb/s which is better than it was.
So apparently it is problem with the drivers. How can I actually make that it would work on Dual-Band?
