DX5401-BO Wifi issue

PalsyP

My ISP has given me this model for my immanent FTTP connection. Am currently configuring it from my existing router.

Anyway, I can connect to it via my iPhones (5S & 11) both 2.4g and 5g. However, even though I use ethernet for my PC(s), it fails to display the SSIDs in the list of found signals.....

My wifi card is an ASUS PCE-N15 11n PCI-E Card - the only driver is dated 19th Oct 2015.

I'm not sure what's going on... It detects my current router and may more around me.

Thought I'd ask here.

Thanks.
