My TV doesn't pick up my Wi-Fi SSID after a router restart

[MultiversalSapien]

I have a VU Premium Android 55-OA and it isn't able to pick my Wi-Fi signal when there is a power outage causing my router to restart. I have Netplus ISP's stock Genexis Platinum 4410 FTTH GPON router and have thoroughly checked all the settings and have already resetted for like 3-4 times but no effect. I, eventually, have to go to Router's WLAN portal and just click on OK as you can see below (idk why but somehow clicking on this OK button without even changing anything makes it work like a charm and the TV again picks up the SSID automatically and immediately and works just fine). It seems like there's an unnoticed thing gng on with either my router or TV. Any ideas?

Try to change the channel of WiFi.Something like 11, 13 etc. Pick a number up to 11.

Did that once, no change. But I'll try all channels and report. Any other suggestions?

It happens only with the TV or other devices too? Try updating router firmware as well.

No need cuz they just replaced my Genexis router with a brand new ZTE one for free and this one has a shit ton of settings and gar better range. No issue on TV or any other devices.
