Assuming 19.07 is using ath10k-ct driver and firmware, you should see this response (and the link he provides in it) by the ct dev to increase the number of stations beyond 32.
What is the recommended way to update/upgrade all upgradable packages with this build?
The wiki says
The package repositories in the development snapshots are updated by the build bots to new versions very often, so it's very likely you won't be able to upgrade some packages due to broken dependencies with kernel or kernel-related packages. In that case, it's recommended to use the Image Builder and make a new firmware image with all packages you need and flash that instead of upgrading through opkg.
So I've to upgrade each time via flashing? What percentage of my settings, certificates and so on will remain? Or is it OK to use
SSH certificates in your user profile don’t by default (If you use those to log into your router), but it’s easy to add them to the list of files to keep during an upgrade
No.
I build only for devices that I personally have (R7800, WNDR3700/v2/3800 and WRT3200ACM)
But you can freely download my R7800 build with scripts and patches, and just modify the device selection to EA8500 (in my .config.init) and then use the scripts to build it for EA8500 by yourself.
Just edit these lines:
# Use "make defconfig" to expand this to a full .config
CONFIG_TARGET_ipq806x=y
CONFIG_TARGET_ipq806x_generic=y
CONFIG_TARGET_ipq806x_generic_DEVICE_netgear_r7800=y
eventually, i did a big jump forward from r9945 to r12138
so, first time with -ct drivers
well, they did a veryy good improvement, also y samsung devices are ok but.. i have TERRIBLE wifi performance with my esp32 devices! average ping 1s (!!) with 30% of packets loss
is this a known behaviour? is there anything i could try?
thanks a lot
