Archer c6 v2 eu 22.03.2

Hi. I just flashed my router according to
I installed wireguard and other stuff for it.
I decided to change drivers according to
"Some users report much improved long-term stability with 5 GHz by using the closed-source ath10k firmware instead of the open-source ath10k-ct firmware. To do this remove the packages “kmod-ath10k-ct” and “ath10k-firmware-qca9888-ct” and instead install “kmod-ath10k” and “ath10k-firmware-qca9888”.
So i removed completely wireguard to get more space. Then I removed kmod-ath10k-ct (its for 2.4ghz)and ath10k-firmware-qca9888-ct (for 5ghz module) via ssh. Then i got error that i have not enough space. Hmmm...ok, new packages have a bit more size, but it sounds strange why official guide offers to do it but itsnot possible.
ok, i decided to turn back to *-ct drivers and i have not enough space again 0_o

  1. Wth?
    I checked /overlay and seems there are no useless stuff there.
  2. What is
    612.0K /overlay/upper/lib/firmware/ath10k/QCA9888/hw2.0/firmware-5.bin
    ? May safely delete it?

Yea, weird isn't it? (there's a long-er explanation)

To fix, just reset to defaults. When you remove a pre-installed package from the image, they are merely marked as deleted - no spaces is saved or reclaimed, in fact you loose some space.

If you want to make an image and select the other WiFi packages, see:

(Don't forget to add the LuCI web GUI to the packages if you make make one.)

ty for fast answer. So this way all embedded packages are marked as deleted if i try to remove it, right. Is it possible to unmark them somehow? editing nvram etc idk. Because router is in another country atm. It will be hard to explain how to configure it . I have ssh atm.

Alternatively, you could also:

  • Create an image of the same version with the correct/needed packages, omitting the ones you don't want
  • Sysupgrade keeping settings

This should work. Apologies for not making that clear above.

Then you could make a SSH tunnel to port 80 or 443 at the OpenWrt's IP and have the LuCI web GUI too. :wink:

First, reset the router

Then, setup extroot:


You missed:

OP can't reset.

Updated fine. Tyvm. But seems luci ui is not available by default.
