How to install Linksys wusb6100m

Asked by William Pabon

Hi:
The wifi card inside my pc apparently stopped working. I bought the Linksys wusb6100m dongle to replace it, but I'm not familiar with the steps to install it, since there are no drivers that I know of for ubuntu. The system recognizes it, as shown below:

williepabon@williepabon-Macmini:~$ lsusb

Bus 002 Device 008: ID 05ac:828a Apple, Inc.

Shown below is the information about my pc:

williepabon@williepabon-Macmini:~$ lsb_release -crid
Distributor ID: Ubuntu
Description: Ubuntu 20.04.2 LTS

Please, help. Thanks.

For diagnostic purposes proceed as follows:

unplug the WLAN adapter, wait a minute
issue the command
dmesg
and note down the time code of the last entry shown.
plug in the WLAN adapter again, wait a minute
issue the command
dmesg
again and copy all lines that have been added to the first execution and paste them into this question document.

Manfred:

Thanks for answering. I'm not totally sure if I'm doing this correctly, but this is the information I obtained following your instructions. For the first dmseg, the last line is:

[ 351.873338] usb 3-1: USB disconnect, device number 2

For the second dmesg, the following lines appeared after the one above:

[ 857.494024] usb 3-1: new high-speed USB device number 6 using xhci_hcd
[ 857.642977] usb 3-1: New USB device found, idVendor=13b1, idProduct=0042, bcdDevice=90.10
[ 857.642982] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 857.642984] usb 3-1: Product: USBWLAN
[ 857.642987] usb 3-1: Manufacturer: Qualcomm Atheros
[ 857.642989] usb 3-1: SerialNumber: 12345678
[ 857.644838] usb 3-1: Warning: ath10k USB support is incomplete, don't expect anything to work!
[ 857.645095] usb 3-1: Unsupported hardware version: 0x5020001
[ 857.645103] usb 3-1: could not get hw params (-22)
[ 857.645109] usb 3-1: could not probe fw (-22)

Hope this helps. Thanks

Well done, but probably not helpful.

The output shows that the system believes that your device needs the ath10k driver, but it fails.

Other people had the same problem and could not solve it, see e.g. https://askubuntu.com/q/799104

Did you check whether the device is supposed to work with Linux before buying it?

Manfred:

Thanks for the info. Regrettably, I did not check if the dongle was Linux compatible because I bought it before my current problem, for a Windows machine. Well then, I will have to start a search for a wifi dongle that works with Linux. Any ideas where to start? Thanks again.
