You guys know the problem, it's been posted about a hundred times and tp-link have either

1) Given people a run around

2) Straight up ignored people

Here's the thing, the Archer T6E doesn't work properly with Windows 10 and the drivers for Wi-Fi adaptors are just bad. When the customer support is telling people to download Asus's drivers for the same Broadcom wi-fi, you know things are bad. By bad I mean, it' straight up false advertising. You say Windows 10 is supported and it is an 802.11ac card but clearly it doesn't work. They just hope that people don't notice the 2.4G/802.11n connection and leave a good review on Amazon.

I can't change the Wi-Fi channel on the Deco M4 so I can't even test if that is the problem. If I force 5GHz in a guest network, it works on super slow 802.11a for some reason.

I don't even care, tell me if I can fix this issue by buying a Deco M9 plus and changing the main channel, I will do it.

At this point the sunk cost fallacy has set in and I didn't realise I had made a terrible decision by buying the Archer T6E. Even worse, I have recommended it to a lot of people on PC building forums I frequent and people ask me a lot for build advice.

Please let me know how I can fix this, I am about ready to trash all my tp-link products and getting a new set at this point.

There are about 10 computers in my office that can't be upgraded past Windows 7 because the old TP-Link PCI cards BSOD Windows 8 and 10 randomly. I have already stopped buying them for my office. I thought the Archer T6E wasn't a budget or out dated card so it wouldn't have problems, oh boy does it have problems.

TP-Link Wi-Fi adapters are HORRIBLE, STAY AWAY.

I have a feeling though, nothing is going to happen about this problem though. People have reported it for years now, tp-link simply doesn't give a darn. My return period is over so this money is lost. This is why I never buy tech products from Chinese companies, they have no loyalty to their customers. Enjoy my money guys, it's the last you will se of it.
