[Solved] Problem setting up tl-wn722n wifi adapter

[Taterman]

Ok, unless you can try those commands while connected, you might get a different adapter that's plug & play on linux.

The adapter I just bought is supposed to linux ready. It's this one. https://www.amazon.com/dp/B002SZEOLG?ps ... ct_details

It says it works on Linux kernels 2.6.18-4.4.3, you have 5.4.0-74.

But those commands might still get it going as it did here:

OK, I'll return it. Is there an inexpensive one that you could recommend?
Many on Amazon don't list which kernel they work with.

[sleeper12]

I have no experience with them, but I've seen Panda & some TP-Link's mentioned here before. Can't give you a specific one though.

[Taterman]

The most recent version I've found is up to Linux Mint 19.2 but I installed 20.2.

You might find one if you scroll down thru this site:

I have that same adapter, it just runs on the integrated ath9k_htc driver. nothing more to do than plug it in and connect to your network. i am on kernel 5.4x

Code: Select all

Device-2: Qualcomm Atheros AR9271 802.11n type: USB driver: ath9k_htc bus ID: 2-1.6:5 
           chip ID: 0cf3:9271 

Code: Select all

Kernel: 5.4.0-88-generic x86_64 bits: 64 compiler: gcc v: 9.3.0 Desktop: MATE 1.24.0 
           wm: marco dm: LightDM Distro: Linux Mint 20.2 Uma base: Ubuntu 20.04 focal

Is your adapter a version 2 like his?

[solarbear]

i pasted the sys info for it, i can get the s/n if that helps

that is a nice adapter though, real fast.

TL-WN722N

[Taterman]

It doesn't say on the box what version it is, just TL-WN722N.

Edit: It says version 3.20

[sleeper12]

Different driver too, OP has r8188eu.

That's interesting, inxi shows:
Device-3: TP-Link TL-WN722N v2 type: USB driver: r8188eu bus ID: 1-8:5

the adapter i am using now is a realtek chipset, it is plug and play also

Code: Select all

Device-2: Realtek RTL8188SU 802.11n WLAN Adapter type: USB driver: r8712u 
           bus ID: 2-1.6:5 chip ID: 0bda:8171 

but alot slower, is it that much different than OPs chipset that the driver has to be fetched from github?

[Taterman]

I'm so frustrated and confused. A lot of this stuff is over my head.

[solarbear]

no need to be frustrated, there are some resourceful fellow users on the case. does your lappy have an ethernet port?

some adapters are plug and play. others have drivers fetched from driver manager, others have to be patched . I had one that had to be patched with ndiswrapper, be thankful that isn't the case here

[sleeper12]

I don't think it matters since the OP can't try a different driver anyway & it's not working as plug & play.

[Taterman]

no need to be frustrated, there are some resourceful fellow users on the case. does your lappy have an ethernet port?

It does, but I need the wifi to work because that is all I'll have soon.

[solarbear]

i have alot of adapters in the boneyard, while i was connected to ethernet, i would plug each one in and check to see if it was plug and play or catered in the driver manager, the plug and play ones i kept. i know the netgear n-150 is a good one, but now that i see that different adapters vary chipsets by version number, i can't recommend any.

it looks like the atheros chipsets are the fastest and best developed

a nifty google search rebounded this:
