cannot connect on non DFS 5G network
Opened this issue · 6 comments
Hello,
I use a Tp-Link AX1800.
It work fine on DFS with any authentication methods.
On the non DFS it either connects and it does no transfer,
or fails to connect with the right password.
I tried to change to WPA2 or change the channels, it has the same behavior.
It is a bug or a configuration issue?
thanks
You are asking in the wrong place. I am a volunteer that helps problems with building drivers, or implementing them on older kernels. Look at the last paragraph of README.md to see where to ask your questions like this.
I gave you bad information yesterday. This vendor driver is not supported on the linux-wireless mailing list.
This driver is a big pile of stinking code, and is not maintainable by anyone outside Realtek, this adding features would be difficult. That said, I have no trouble connection to any of my 4 APs. Two are 802.11n with separate SSID for 2.4 and 5 G bands, one is 802.11ac (Wifi 5) with separate SSIDs, and there is a TP Link Eagle Pro ax1500 (Wifi 6) with a single SSID for both bands. Most of the channel selection by the APs is automatic. I have not done a lot of testing with the RTW8852AU dongle, but other of my Wifi 6 cards have roamed between the 2 bands on that last AP.
I have posted the output for the 'iw list' command while connected to the 5G band of the Wifi 6 AP.
How does DFS come into the picture? That is not something I have run across before.
hi @lwfinger ,
In fact I have 2 adapters.
I switched to the D-Link DWA-X1850 and it works fine, both networks.
The problem is related only to the Tp-Link Archer TX20U Plus on accessing the Non DFS Network.
Is seems to be related to MU_MIMO settings, somehow; when disabled I can connect but does work at low speed.
The router I use is Mi AX-9000.
Does your 'iw list' show any MIMO enabled?
the DWA-X1850 shows:
george@george-B560I-AORUS-PRO-AX:~$ sudo iw list | grep MIMO
* [ MU_MIMO_AIR_SNIFFER ]: MU-MIMO sniffer
thant's all
iw_lists.txt
Your file had two different wifi devices listed - "Wiphy phy2" and "Wiphy phy0". Only the latter had the MU-MIMO capability.
I expect that you other device besides the DWA-X1850 can connect. What is that device? Looking at its driver might offer some clues.
