Windows 10 connectivity, Dell Latitude E7440 - ZTE MC888

[NottsRob74]

So, I’ve been gifted an older Dell laptop (appx. 5 years old) and have just started with the 3 5G home BB. 
 I can’t, for the life of me, get the laptop to recognise the ZTE MC888 router. I have perused the ‘net, including this site, and have tried all the usual - both 2.4/5ghz separately, literally been through every wireless channel on both 2.4 and 5ghz, reset the router (even though I know this isn’tt the cause as every other device - iPad/phone, Ring doorbell, PS5, blah blah…connects successfully) et al.

 Laptop wise I have reinstalled the network adaptor (device manager, etc) all to no avail. 
 Can anyone out there offer any further advice?

Many thanks, 

Rob.

Hello, Rob. 

Along with Geluk's advice, can you also confirm if the laptop is able to detect other Wireless Networks?

Try turning off router security [temporarily]- does the laptop then see it in WIFI connections?
