This is weird, because i'm also using 8814au chipset on Kali 2017.3 @ kernel v4.14 and it works great over here. will anyway take a look at it soon. The __vfs_read error is related to kernel v4.14 support.

Have you tried using the "realtek-rtl88xxau-dkms" from apt-get instead?

[shell-sh0ckR]

sudo modprobe 8814au:

modprobe: ERROR: could not insert '8814au': Exec format error

[kimocoder]

Weird. I build from repo and it works just fine.
Will look at it when I got time & I have ny laptop and adapter available.

[kimocoder]

Try "updatedb" and "locate 8814au.ko" remove them all from kernel space.
Then build from repo and install it again ..

Be sure it's NOT in DKMS folder too, and use "make RTL8814=1 && make install RTL8814=1" instead of DKMS installation.

@shell-sh0ckR

[ 3636.233407] 8814au: Unknown symbol __vfs_read (err 0)
[ 3664.285700] 8814au: Unknown symbol __vfs_read (err 0)

You are using kernel>= 4.14 with a module compiled on kernel < 4.14 or with outdated code.

The __vfs_read call was removed on 65a6213

[kimocoder]

@CGarces provided information needed information. Remove (all) current installations of 8814au.ko and compile / build it on kernel v4.14.

__vfs_read error is related to kernel v4.14 support, which is supported by the driver.

[kimocoder]

It works.. tested many times. Just be sure to have dependencies installed, like "bc" and the CORRECT "kernel-headers"

[shell-sh0ckR]

@kimocoder could you please so kind to add here a step by step instruction how you built it from repo please and how to install the correct kernel headers ? cause i followed your instructions above and it didn't work :-/ ...would be great to see what i was doing wrong ....thx mate
