ALFA AWUS036ACH not working in USB3.0 mode on 2.4Ghz networks #16

Hi @dill-shower I'll put this on my to-do list. |
|
My AWUS036 only has a USB2 interface. In the USB connector, what color is the spacer tab? |
Hi. Blue. It's awus036ACH model. |
Since usb3 is of no use with the 2.4 GHz band, select 0 or leave the parameter out. In fact, I am pretty sure that is what I recommend in my AP Mode guide: The Main Menu for this site is: https://github.com/morrownr/USB-WiFi The AP Mode guide is menu item 8. |
|
@dill-shower - One more test is to run 'lsusb -v | less' and scroll down to the entry for the AWUS036 entry and check the value of bcdUSB. |
3.00 if I use rtw_switch_usb_mode=1 |
The region only matters if you are running AP mode. Are you running AP mode? In fact, you probably don't need to set the country code unless you are running AP mode and maybe not then.
Have you installed something that could account for the above?
Not sure what is going on there. I'll have to take a look. |
Yes. It's LKRG module. This should have nothing to do with rtl8812au. |
|
It should have nothing to do with rtl8812au but it is showing up in the onscreen log from the script. Can you show me? $ dkms status |
Deprecated feature: REMAKE_INITRD (/var/lib/dkms/lkrg/0.9.7/source/dkms.conf) |

@dill-shower - Please extract the section on the AWUS036 that comes from 'lsusb -v'. I want to see if there is a definitive variable that will let us set USB 3 in the drivers. |
Now without usb3 flag output is this. If need with usb3 flag please write Bus 001 Device 004: ID 0bda:8812 Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac 2T2R DB WLAN Adapter |

That post is sufficient. I had hoped to see something that indicated the device was USB 3, but running as USB 2. So far, nothing seems to be appropriate. It does not appear that we have any way to tell. I am looking into the code that does the change to see what it does and why it is not auto-adjusting. There is one setting in the efuse that would prevent it from changing, but that seems not to apply to your system. |
Brief description of the problem: when setting the config to use usb3, the adapter connects to 2.4Ggz networks, but the connection speed is very slow (30kb/sec).
This problem does not appear in
A) Past driver version
B) On 5Ghz netwoks
C) If I delete thin config parameter rtw_switch_usb_mode=1
P.s: setting the region in config also doesn't work. I set to use US region, iw reg get command shows that region 00 UNSET. Self region setting via iw reg set works. (but it's don't fix speed problem)
I dont use VM. It's host OS Debian bookworm stable
options 8812au rtw_switch_usb_mode=1 rtw_drv_log_level=5 rtw_dfs_region_domain=0 rtw_country_code=US
Device logs from save-logs.sh when I connect to 2.4 network and try open speedtest
