Realtek RTL8188EUS 802.11n in Wireless network Aadapter: unavailable Solved

Post by Voltaire »

TP-Link WN725N(US) Ver: 3.0
Driver manager shows driver in use: rtl8188eus-dkms (open source) Version 5.39~focal2, installed from https://github.com/Munazirul/rtl8188eus
(etc/modprobe.d/realtek.conf:
blacklist r8188eu
blacklist r8188eu.ko
blacklist 8188eu.ko)

I have tried many different suggestions, including stepping down my kernel from 5.18 to 5.15. Nothing works.

The dongle came with a linux driver, but it targets kernels now deprecated and runs only with numerous errors.

The default Linux driver didn't even recognize the hardware.

Installing DKMS packages for Realtek via Synaptic always fails with what I assume is a read/write failure, but not before turning my CPU into a heating element trying to correct the error, and still failing.

Network manager shows the dongle, but says it is 'unavailable'.

Does anyone have the faintest clue what is going on here?

2 wlan phy0 unblocked unblocked
3 wlan phy1 unblocked blocked
4 bluetooth hci0 unblocked unblocked

Note: hp-wifi and hp-bluetooth are on the Qualcomm card which refuses to work no matter I've tried. There is NO hardware switch, and the relevant keyboard function key says the WiFi network is on (white light). Pressing it changes the light to orange for a few seconds before changing back to white. This failure led me to get the TP-Link dongle. The function key still says the network is on, and still changes back from orange to white when pressed.

You may have to remove the internal wifi to clear the hard block, see video https://www.youtube.com/watch?v=eEUh9y5 ... h%E2%84%A2

You're a f*&%$#ng legend, Jeremy. And I'm a dope for not thinking of it. Removed Qualcomm, machine came back up and WiFi was just there.

I suppose I got a good cleanup of my build out of it, uninstalling a pile of kernels and drivers I didn't/don't really need.

Thanks again.
