2.4G wifi... your router (wifi) need a 2.4G signal network.
Discussion
Yes the wifi connection is fine. It’s some setting of the router that’s blocking connecting to pools so no hashing occurs
Ok, so connection isn't the issue. Next step is to check if it's related with the DNS (resolv the pool domain) or some port blocking in the router.
With a computer behind the route (use the same that bitaxe), could you try to resolv the pool domain? search for curl in case you want to test.
I am not focusing in bitaxe configuration because you said that using another network, without any change, the bitaxe works.
Thankfully got it working. Turned out it was a firewall setting that must not have actually disabled despite GUI saying so until router was reboot. Appreciate your willingness to help 🤙
