I would think wireless config was invalid for the driver.
Between 4.5.6 and 4.5.7 a whole different driver is used, this means the wireless devices have been changed in the wireless config.
Though if you want a clean wireless config without resetting, you can get it from /rom/etc/config/wireless if you still have a backup you can update the devices, be aware that alot of wifi features other than the most basic ones probably are unsupported, luci also doesn’t work fully with wireless settings.
Problem is when i updated v4.5.6 → v4.5.7 keeping the old settings and tried also resetting. After update router was working but after i did first restart /etc/wireless folder got deleted.
The same thing happened with and without reset after upodate.
@alex_zheng what are the changes from version 4.5.7 release5 to release6? In the changelog on the download page there was no change in the description. My question is whether only the option to select the country was added to Luci or whether there were other changes.
Also, could we talk about the advancements in resolving the 2.4 GHz driver issue? Has the cause of the problem already been found?
This configuration always comes back and in this version it came back, polluting the log with a lot of information and has already been corrected in another post.
uci set system.@system[0].cronloglevel="10"
uci commit system
uci show system
/etc/init.d/gl_timer restart
detail that the last command causes gl_timer to restart, it didn’t work through ssh, I had to go to Luci and restart the process located in System/Startup
4.5.7 R6 has fixed the issue where I wasnt able to set the country code in Luci
But the same issue where I set channel 128 / 160hz 5ghz is still not working, this issue applies to all of the 100+ channels on this firmware, if I force set channel 64 DFS that works, or channel 60, that works too, but 100, 102, 108, 116, 120, 124, and 128 all scan for about 5 mins or so and then default to channel 40, but it works fine on 4.5.6.
in any app it is limited to 19dbm for 5ghz and 17 for 2.4ghz regardless of what you change. As the dev already commented, it is a bug that has yet to be fixed. If you have any doubts, update there and do your test, put it in Europe and check if it limits the power.
