Hi, I recently purchased a wifi booster Quanta QTAA600 with realtek 8811 (since I could not find one with intel unfortunately where I live). And It does not seem to work. how should I install it (they provided a mini CD for the drivers … in 2025 lol, so not able to read it). What should I do? Thanks
When buying WiFi Intel is no guarantee things work, for this case you should have done a search on “wifi Quanta QTAA600 linux” and unless you find some useful link (incl. older links the things are note working) do not buy this device.
But for a start, start with giving us the output of lsusb, for my USB WLAN device:

Hi thanks for your answer (I have checked beforehand the models, but could not see anything clearly compatible). Here is the output. Not sure which one it is, I have the integrated wifi module in my laptop already and this Quanta booster.

Both devices seems to be supported by Linux:
Does the integrated wifi module work?
You should be able to find out which is the external device by unplugging it and checking with lsub which device disappeared.
Based on this topic it could be that the driver is rtl88x2bu but that seems currently not to be building for Tumbleweed:
thanks. I found which one it is:
Bus 001 Device 004: ID 0bda:c811 Realtek Semiconductor Corp. 802.11ac NIC
Here is the output for the other command:
lsusb -v -d 0bda:c811

That adapter can work but seems like many people have problems with it:
So 8 probes where it works and 31 more pages of setups where things do not work.
For those 8 instances where the cards works you see a link to:
I would try to follow these instructions.
Should be working out of the box with rtw88:

So I finally solved this mystery which actually was not a real one: I have tried it on my old laptop with MX Linux where I was able to choose between the integrated wifi and the realtek and it works fine with the closest wifi but not so well with the one downstairs which is the one I was targeting with this wifi booster. I guess I need to get a more powerful one. So on my more recent laptop; it was probably recognized but since I did not see any difference, I thought it was not recognized. Thanks a lot for all the help.
Okay, good you found thew actual problem and documented it here.
On WiFi boosters:
- I see it is a USB dongle with one antenna.
- Better chose an adapter with multiple antenna’s, I use USB-AC58
- Also the antenna of the other side is relevant
- Placement of the antenna’s can make a major difference
- get the device connected via a longer USB cable and check everywhere in range up till 3…5 meter around your computer.
- Use
nmcli dev wifito get a list with of all WiFi AP’s sorted on signal level, get for your AP the signal > 50, the larger the better. - Use
while sleep 1; do nmcli dev wifi list bssid 01:9B:E5:57:9D:3A; doneto monitor the signal level over time, replace then MAC address by the address of your AP. - Quality changes every 5 cm
- Best place is where there is a most direct line-of-sight with the other side
