[SOLVED] Video Problem - Was: WIFI-USB Adapter RTL8111 Not Working [Solved]

[NevilsStation]

The little internal PCI wifi nic, with cables to the front panel antenna, works.

The external dual-antenna WIFI-USB adapter doesn't.

I followed the steps here:

viewtopic.php?p=643894#p643894

Then disconnected the internal wifi nic and rebooted.

I connected the USB wifi.

My external dual-antenna WIFI-USB adapter is recognized as a Realtek in System Profiler & Benchmarks.

I can see it in MX Network.

I tried rebooting, again.

It will not connect to wifi - no evidence it's even trying to do so.

Any suggestions, please?

It is very important that you provide the hardware specifications of your machine. If it is a video problem obviously the video card is important. At times it may not be clear what component may be the problem so give as much detail on hardware as possible. The preferred way to provide this information is Quick System Info available from the menu. When you click on it the system information is copied to the clipboard. Then paste that into your post.

Help requests must include information about the computer's system and hardware. The best way to do this in MX Linux is to run the Quick System Info (QSI) utility found in the main menu or in MX Tools. antiX users may run inxi -Fxxxrza in a terminal.

... But did you first see / know if they were the same chips or that was the required driver for yours, too?

Reinstalled the internal nic so I could connect to the Forum from the actual PC and send the Quick Info.

Note: I believe that the Qualcom is the internal nic - which I'd removed for the 5th time (to try to isolate the USB nic) late last night.

The USB device is labeled "PCI" - could that create a problem?

Thanks.

They both appeared, to me, to be the same RTL8111.

... but.. it's a bit confusing :

What's the best way to UN-install that driver/those drivers, please?

Would something like this work?

Code: Select all

sudo dkms remove -m 8192cu -v 4.0.2.9000.20130911 --all

sudo dkms uninstall -m 8192cu -v 4.0.2.9000.20130911 --all

[Huckleberry Finn]

In fact, the best is: Plug the device, then:

Code: Select all

lsusb ; inxi -nxxxz

Just to make sure first what device we're talking about and what driver it needs exactly etc.
