One laptop wont connect to wifi

[GaryB17]

Hi all, odd problem happened today. We have many devices successfully connected and getting great speeds, this morning when I booted up my laptop it just doesn't connect to the EE router via wifi all of a sudden.

Windows 11 built in NIC, no ethernet port. Its getting IP via DHCP and al looks fine. The router is connected to the internet as I have other devices which are fine. I can also connect to a hotspot on my phone using the wifi, and can also connect to other networks including the free EE WIFI which I'm on now.

I have tried updating NIC drivers, ipconfig /flushdns | ipconfig /releasedns | ipconfig /renewdns, reset the network card and pretty much everything else including disabling defender AV/Firewall.

At this stage I'm pretty sure its not the laptop NIC as it can connect to other networks fine and even my local networ via the phones hotspot..

Anyone have any ideas?

This is the wifi settings with all correct details. Says connected, no internet which is incorrect as other devices are wrking fine.

Hi @GaryB17 

Is it an old laptop which uses the 2.4: channel only. Tried using comparability mode. 

Thanks

Hi, its fairly new, a Surface 5 with Intel wifi-6 ax201 NIC.

Worked perfectly until this morning. In the EE hb it says disconnected but it does have the IP assigned by DHCP.
