Hello, I found many topics about Archer C6 5Ghz performance but seems like noone had this problem I'm having. I simply cannot uninstall ct packages and install non-ct packages because there is not enough space. I have 524 KiB free out of 832 KiB and the two packages I need have together around 100% of all my space. Also deleting the ct packages won't free any space. How can I then change the packages? And why my disk space is so low and temp space is around 60 MiB?
temp space is in RAM.
is it EU or US device? WHat other package changes you did?
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):
Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
Select your device, click tiny arrow, put - in front of packages you want to remove, add the packages you want to the list.
Deleting packages shipping with the image won't free any space, it actually allocates additional space.

It is EU. No other packages installed. Factory image 24.10.3.
From now on it is sysupgrade images, must be long time idling after factory instal 2-8 months ago....
Current version is 24.10.4.
opkg update
opkg install owut
owut check -v -r kmod-ath10k-ct -r ath10k-firmware-qca9888-ct -a kmod-ath10k -a ath10k-firmware-qca9888
# owut upgrade -v -r kmod-ath10k-ct -r ath10k-firmware-qca9888-ct -a kmod-ath10k -a ath10k-firmware-qca9888

My bad, actually already upgraded to 24.10.4.
That could work, thanks a lot
Modules replaced too?
I did sysuprade from image from firmware selector with packages replaced and it seems it did the trick. Thanks
Little offtopic but... On stock firmware I got around 900Mb/s through LAN, but here it seems around 640Mb/s tops, I guess there's no way around it?
Very on-topic.... Enable firewall soft offload (hard has drawbacks)
I tried both. With HW (currently) it's around the 640Mb/s as I said and with SW it was around 400Mb/s I think. But I'll try again tomorrow.
Apply locally the following:

hw offload is same sw offload just with other interface set undermining wifi roaming.
additionally you can un-tag wan port (ie untagged in switch conf, and interface changed to eth0 in both connections) for some more cpu relieving.
How to apply it?
Edit files on the device. Start by untag, it makes something like 600->1300Mbps forward speed if SoC has 2 phy-s connected , yours has one, youll land sub-gbps.
WAN is in VLAN 2 and already untagged, when I change interface from eth0.2 to eth0, connection isn't working.
untag vlan 2 on system (CPU) port.
Software offload and untag and still around 660Mbps
