Archer T3U AC1300 plus - Not working on 5ghz / 80mhz!
My Stick works but it doesnt get the full Speed done.
It crashes when i try a higher Channel on 80Mhz on my Router. But i need that to even reach the 867Mbit/s.
Works on Channell 40 with 40mhz but doesnt on 80mhz. It just crashes and wont find any Wlan.
I did everything standard like reinstall drivers etc.
Some while ago i read that the Chipset simply does not provide to work with 80mhz. If its true its a scam to say its speed is up to 867mbit/s just because it works
with lower speed 5ghz.

@gruessedich_o7 Hi, have you tried to install the following driver: https://community.tp-link.com/en/home/forum/topic/509006
By the way, can I have the model number of your Host router?
What is the current maximum link speed on the Archer T3U Plus when it is connected to the host router?
Thank you very much and best regards.

Hey David, thanks for the reply
I tried the Driver now. It did not change anything, it still stops working at 80mhz which is needed for higher speed.
Router Model Number: CGA6444VF
Max speed is ~250Mbps down and 53Mbps up.

Hi, Thank you very much for the update.
"Max speed is ~250Mbps down and 53Mbps up."
- I think these are the download/upload speeds.
How about the wireless link speed here: How to check the associated/link speed on a wireless client
Have you checked the 5GHz wireless channel when you set the Vodafone WiFi 6 station/CGA6444VF to 80 MHz?
You mentioned earlier that "It just crashes and won't find any Wlan".
I think Archer T3U Plus mainly used band 1 of 5GHz(channel 38/46 over 40mhz, channel 42 over 80mhz). I wonder whether the Vodafone router used another channel over 80mhz, which might cause the crash of 5Ghz WiFi.

Wait for your reply and best regards.

Heyy David,
the wireless link speed is 400.0 Mbps on 40hz and ~867.0 Mbps when i swap to 80mhz but it disconnects few seconds after and disconnects the Adapter aswell(have to replug it in the USB 3.0 slot)
I tried it on the Channels 40 and 44. The Vodafone Station has Channel 36 up 64 in steps of 4 and 100-140 also in Steps of 4.
Best regards.
