WiFi connecting to only certain devices

[GSWoInternet]

Hey all,

I have an EasyBox 804, and had no problem at all for the past two years.

I bought a new computer and tablet, tried connecting it to the internet, and both spit out an 'valid IP not found error'.

My old laptop, my phone and my Alexa are all connected and working fine.

I restarted the router a couple of times, no help at all.

I updated the firmware of my router too, nothing works.

I know the WiFi cards of my new laptop and tablet are not shot, because they work perfectly fine tethered via Hotspot to my old laptop.

Should I request a new MIC and try resetting the router?

Any help will be appreciated.

Regards
