Tab A 2019 SM-T290 2.4 Ghz Wifi stopped working after firmware update

[Cely1]

My Tab A 2019 was updated with the latest firmware last sunday 23 of august 2020. Since then all wifi networks with 2.4 GHz are not visible anymore and tablet can't connect to them, even if configured manually.

Only 5 GHz Networks are working since the update. It seems that the update disabled the 2.4 GHz radio.

Rebooting router/wifi, rebooting tablet, deleting everything, manually configure the network nothing helped.

Please fix that.

Amazing! - after a second update cycle - the 2.4GHz WiFi is working perfectly again! Thanks Atesz!! - I appreciate the heads-up. And Samsung - it should not take you 6 months to (a) discover this issue (b) fix it, and (c) ignore your customer forum throughout the process. Apology accepted.
