I've reactivated a RUT240 which has not been in use for some months. I started by resetting the configuration and configuring the LTE connection.
While the connection to the Mobile network is working as expected, I have a significant performance problems for WiFi clients:
- When connected via LAN (cable), the performance is great and I can ping the RUT (192.168.1.1) with times of 1ms or less
- When connected via WiFi, the performance goes down. The ping to the RUT varies between 20 ms and >1000 ms. It seems like the package handling is somewhat failing. Sometimes, the connection then seems to recover and I get a ping of < 10ms, but not as good as for LAN.
I have updated to the latest factory FW 1.14.3, have changed WiFi security to set it to AUTO or even just WPA-PSD (no WPA2), should somehow the security overhead cause the router to have high load.
Is there a way for me to troubleshoot where the problem originates from, e.g. via the console? I have tried also different WiFi clients, so exclude this as a source of problems. Also a factory reset I did like 4 times by now.
in case there are performanced-optimized WiFi settings that are recommended, I'm happy to apply them. The System Info on the dashboard in the WebUI shows <20% CPU load. But when I go to System Information, I see something like:
||1 min: 80%; 5 mins: 91%; 15 mins: 83%|
As of now I'm not using any additional services, i.e., no VPN or whatsoever. It is a factory default config.
Thank you for any support
