Wi-FI Dongle problem

#1 Post by torx » Thu Sep 06, 2018 12:16 pm

Hello to the Forum. I've received great help here before and I am looking forward to your further assistance. :happy:
My son sent me a TP link TL-WN722N (version 3) Wi-FI dongle for my birthday. :happybday: reference this post> https://forum.mxlinux.org/viewtopic.php?f=107&t=45847
He told me that he was going to get me one for my birthday and I asked him to try and get me a version 1 if he could. He ordered it from amazon and in the original listing it did indeed say it was the V1 with the Atheros chip. But my son didn't dig thru and see that the V3 (rtl8188) is what they are selling now, so thats's what I received.
Anyways i can "sometimes" make this dongle operate. But it's a real hair puller for me but when it does operate it works GREAT.
Before it operates, ( when plugged in) I have No networking interfaces that will operate. The dongle causes the Network Manager freeze, or times -out when it doesn't freeze etc. Once that I get it going though it is smooth sailing until i unplug it or reboot. When I unPlug it then my other interfaces go back to normal. When i can get it to operate it is because i mess with iwconfig, ifconfig, rfkill and/or restarting Network Manager and then all interfaces operate. I tried to compile the drivers from the OEM website but that was an error all the way through and never would compile., I did get some drivers (RTL8188eu) from git hub that I compiled and those are what I am using. My machine had already had the Realtek firmware files installed from the Repo.
I also have a different laptop that is running Manjaro Linux (Arch based). In that laptop this TL-WN722N (version 3) dongle is "Plug and Play" nothing that I had to do to it at all! I did notice that Manjaro assigns the device a strange identifier. The built in WiFi card is wlan0 but when I plug in the dongle its' identifier is wlp0s29f7u2. I mention this because my MX-17 sys seems to have a problem assigning an identifier? I don't know maybe I am wrong on that.
I am definetly a noob at Linux and I need some help please. Thanks in advance. :confused:

I recently upgraded to the 4.15 kernel on tis MX17. The Manjaro is still at 4.14.
Could that be the problem?

Manjaro might be using a "staging" wi-fi driver in the kernel, many of which Debian doesn't enable. However, the Liquorix kernel does enable many more of those, so that might be worth a try.

Debian would also give you those funky "predictable" interface names, but MX has a workaround to supply the old familiar ones.

Thanks for the reply Stevo, I don't know what Liquorix is but I'll check into it promptly. :exclamation:

Im getting ready to find out, LoL!

Code: Select all

Setting up linux-headers-liquorix-686 (4.18-4.1~sid) ...
Setting up linux-image-4.18.0-5.4-liquorix-686 (4.18-4.1~sid) ...
/etc/kernel/postinst.d/initramfs-tools:
update-initramfs: Generating /boot/initrd.img-4.18.0-5.4-liquorix-686
I hope it boots......

I tried different Liquorix kernels but none would boot. :frown:
Back to square one.
but MX has a workaround to supply the old familiar ones.
Possibly the workaround is the problem? I don't know.

Any Ideas?

We backport Liquorix kernels for our own test repo, and they can easily be installed with the MX package installer. Those Sid builds you installed might not be compatible with MX. We have a whole thread on Liquorix kernels that also warn if any outside DKMS drivers, such as proprietary Nvidia video drivers, need to be updated to work on the new kernel.

But you can also run "inxi -N" in Manjaro (make sure inxi is installed) to see what the name of their working driver might be.

That is a good idea!
I actually tried the Liquorix from the MX repo too.
And thanks Spandy thats the first thing that i tried...
I appreciate your helps. I'll probably be back at it tomorrow have a great night!

Re:SOLVED (not fixed) Wi-FI Dongle problem

#10 Post by torx » Wed Sep 12, 2018 10:02 am

Sorry that it's taken this long to get back to this but I got called out of town on an emergency family matter....

Since my return I have tried most everything (inxi -n in Manjaro) to installing different OS's as 'bled' mentioned.
Still nothing worked on this ThinkPad x40. The problem is THIS machine apparently...

I have taken a snapshot of THIS machines OS, put it onto a usb stick and ran it on other machines and the WIFI dongle DOES work on them but NOT on this machine.
It is a hardware conflict somehow...
I will keep trying to resolve (fix) this issue when I get some more time and patience with this machine.

Thank you for your help and I did learn a lot about Linux through this escapade though. :happy:

Marking this as solved but not fixed
