Very slow WiFi for GB connection

Installing and Using OpenWrt Network and Wireless Configuration
21

I’m using hynman’s latest master build with the CT drivers (default).

Only difference I’m seeing that will make a difference for wifi is selecting a country code & selecting a manual transmission power.

Beyond wifi config multiple people tweak with CPU parameters depending on their use. A simple way to get max performance is to set the CPU to the max frequency (1.7ghz) if your priority is max speed (see if this helps, just copy paste the whole blob in, to reverse it you can restart your router or replace the performance with ondemand in the command to revert to default).


echo performance > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor; echo performance > /sys/devices/system/cpu/cpufreq/policy1/scaling_governor

With default openwrt you don’t have access to the two NSS CPUs like proprietary OEM drivers do. To get OEM-like speeds you need these additional CPUs. There is a ton work on the drivers and several versions of drivers are available to advanced users that want to compile their own firmware:
