AC1900 Archer T9E Issues

Hi,
I bought and installed this adapter 7 months ago and had no problems until last night. While watching Facebook videos, my connection dropped which I thought was just one of my normal connection drops resolved by refreshing the page. This time however I couldn't get the connection to return. I have tried using the 2 different drivers which has made no difference, tried windows troubleshooting which hasn't found a problem and tried moving the adapter to a different PCI port also to no avail.
What's happening is that when I try to connect to my router (2.4GHz and 5GHz), Windows is sometimes saying it can't connect to the network while other times it is connecting but with an extremely slow connection speed. The adapters status page in the network control panel shows 6.5mbps with a strong signal. A general speedtest using the BT Wholesale system or speedtest.net is not completing due to the poor connection.
I have tried 2 drivers, changing the PCI port, fully uninstalling the device and it's driver and software from the device panel and the tp-link installer.
Drivers used were:
1. Archer T9E_V1_151026 (Version 6.30.223.228 Dated 06/02/2014)
2. Archer T9E(EU)_V1_170831_Wins (Version 7.35.317.1 Dated 06/10/2015)
I am using Windows 10 Pro X64 Version 1709 OS Build 16299.248. The last update it shows being installed is the 2018-02 Cumulative Update KB4074588 installed on 13/02/2018 which is over a week before I started getting the issue.
I am currently using the Realtek USB adapter I had beforehand on the same computer with no issues. I can't test the adapter in another computer as I only have this one.
Any help would be greatly appreciated!

I couldn't be more upset. I believe the card was not even tested before the replacement was sent to me.
I get exactly the same results with the new T9E adapter they sent to me. Although the box was not sealed and the anti-static bag was also opened already, I checked the serial number and confirmed it's not the same adapter I sent to them. It's a new one.
But the results is exactly the same:
- cannot connect to 2.4 GHz SSID
- Can connect to 5 GHz , but adapter status first connects at 1300mbps, and in a few seconds it begins to decrease until it reaches 6.5mbps
- It's impossible to use. web pages timeout while loading. Tons of packet loss jitter and delay to ping the default gateway, the IP address of the router (Archer AC5400).
- It's also weird that even before I try to connect to any wi-fi network, windows only shows 3 SSIDs available. IWhen I use an older tplink wireless-N adapter, it detects more than 10 SSIDs detected
I'm using the same driver that was running perfectly fine until end of January, which is the one found in Tplink support/download pages. Tried several others, each with different behaviours.
The results points me back to a driver/windows/compatibility issue. I'll stop doing any other troubleshooting until the next windows oficial update is released, maybe this month.

Hello,
I did not have any problems connecting to neither 5GHz nor 2.4GHz networks. Although it was awfully slow. Best I could get was somewhere near 35Mbps. On the same network, other devices like notebooks or smartphones achieved 120Mbps with no problems.
I was reading this thread and I started to monitor the reported connection speed.
The reported connection speed through windows network status page was 54Mbps.
I started checking various network settings and I found on the security page of "Wireless Properties" window that it was connected through WPA2-Personal with TKIP encryption. I changed that manually to AES encryption and after reconnect... 1.1Gbps connection speed and internet speed was 136Mbps.
Here are some screenshots:
Before:
After:
Here I changed encryption type:
Please let me know if it works for you.

Blue led on solid all time
2018-07-26 10:44:54
Once I boot up my desktop the led goes from dark to flashing blue to solid blue and stays solid blue until my desktop is shut down. Does it not flash to show activity?
