I am attempting to install this on Rocky Linux 9.3 to use my TP-Link Archer T2U Plus WiFi adapter, and I am getting an error while compiling that I am not familiar enough with to understand.

Here is the make.log: make.log

I'm also not entirely sure if this is the best driver to use, but I've tried a few others and none have worked so far.

Hi @bobbyl140

From the README:

Note: Red Hat Enterprise Linux (RHEL) and distros based on RHEL are supported by Red Hat devs due to the way kernel patches are handled in Red Hat. I support knowledgable RHEL developers if they want to merge the required support and keep it current. I reserve the right to delete this support without notice if it causes any problems.

Current RHEL maintainer: none

My opinion is that you might be better off, if running Rocky, to get an adapter that can run with in-kernel drivers. I can help you discover the in-kernel drivers that are available to you if you are interested.

bobbyl140 commented 3 months ago

Ah, I'm sorry I missed that. If you have any WiFi adapter recommendations I'd love to have them, I'm ideally looking for something that would support monitor mode either with a built in driver or a 3rd party one, but depending on the existence of said driver, it's not a requirement. Thank you!

We need to first figure out Rocky's kernel can do for us.

I'm ideally looking for something that would support monitor mode either with a built in driver...

Run the following and post the result:

$ cd /usr/lib/modules/6.6.13+bpo-amd64/kernel/drivers/net/wireless/mediatek/mt76/mt76x2 $ ls mt7*

bobbyl140 commented 3 months ago

I substituted the kernel version in that command for $(uname -r), as I have a different kernel version. The output is:

mt76x2-common.ko.xz
mt76x2e.ko.xz
mt76x2u.ko.xz
morrownr commented 3 months ago 
mt76x2-common.ko.xz
mt76x2u.ko.xz

That tells us there is an in-kernel driver for the mt7612u (AC1200) chipset. That probably means the mt7610u chipset is also supported but we would have to check that.

Go to:

https://github.com/morrownr/USB-WiFi/tree/main

That is the Main Menu for this site. Menu item 1 gives some good to know info and item 2 is the Plug and Play List. In that list you will find sections for recommended adapters with mt7612u and my7610u chipset.

Questions?

bobbyl140 commented 3 months ago

Nope, no questions! Thank you so much!

morrownr commented 3 months ago

For monitor mode, given the drivers you have available in your kernel, I'd recommend the following:

ALFA AWUS036ACM ALFA AWUS036ACHM

morrownr commented 3 months ago

I happened to think about something. You will see a section in the Plug and Play List about the mt7921au chipset (WiFi 6e) or even the mt7925 chipset (WiFi 7). It is highly unlikely that Rocky has those drivers as the mt7921au driver was added to the Linux kernel with kernel 5.19 and the mt7925 driver was added to kernel 6.7. With Rocky using kernel 5.14, the mt7612u chipset and driver are the most modern available but it works well with monitor mode and is faster than most people need so it should work for you... but don't order the more modern chipsets as Rocky won't have the drivers yet.

Cheers
