TP-Link Archer T3U [Realtek RTL8812BU] Download speed problem 6.0.2-arch1-1 #160

Open newedgex opened 2 years ago

newedgex commented 2 years ago

Hi, Below is my configuration and tests (multiple) and it seems that the only way to have at least a bearable speed is to have the dongle plugged into a 2.0 USB while being connected to a 5Ghz AP, all the rest have very slow downloads. It seems to be affecting only the download though, the upload seems to not be affected.

Below the results of my tests and configurations :

Config 1 (USB 3.0)

- Linux ws 6.0.2-arch1-1 #1 SMP PREEMPT_DYNAMIC Sat, 15 Oct 2022 14:00:49 +0000 x86_64 GNU/Linux
- aur/rtl88x2bu-dkms-git 5.13.1.r166.3d25a90-1 (+41 1.37) (Installed: 5.13.1.r173.88f80f7-1)
- Bus 002 Device 002: ID 2357:012d TP-Link Archer T3U [Realtek RTL8812BU]
- Port 4: Dev 2, If 0, Class=Vendor Specific Class, Driver=rtl88x2bu, 5000M
- USB 3.0 Port , config forced with 
cat /etc/modprobe.d/99-RTL88x2BU.conf 
options 88x2bu rtw_switch_usb_mode=1

Test 1 : 2.4Ghz AP

fast.com Results : 
- Down : 10Mbps

Test 2 : 5Ghz AP

fast.com Results :

speedtest.net Results :

===================================== Config 2 (USB 3.0) without forcing 3.0

- Linux ws 6.0.2-arch1-1 #1 SMP PREEMPT_DYNAMIC Sat, 15 Oct 2022 14:00:49 +0000 x86_64 GNU/Linux

- Bus 002 Device 002: ID 2357:012d TP-Link Archer T3U [Realtek RTL8812BU]
- |__ Port 4: Dev 2, If 0, Class=Vendor Specific Class, Driver=rtl88x2bu, 5000M
- USB 3.0 Port , config NOT forced through modprobe.
NOTE: since it's still 5000M it's the same config as with Config 1 section so results won't change.

===================================== Config 3 (USB 2.0)

- Linux ws 6.0.2-arch1-1 #1 SMP PREEMPT_DYNAMIC Sat, 15 Oct 2022 14:00:49 +0000 x86_64 GNU/Linux

- __ Port 10: Dev 7, If 0, Class=Vendor Specific Class, Driver=rtl88x2bu, 480M
- USB 2.0 Port , confirmed also by the 480M

I have already verified with multiple devices (other Arch linux laptops) having no problem whatsoever getting the full available bandwidth from the same exact AP (both 2.4Ghz and 5Ghz)
