Dell Latitude E7250 won't connect

[Sparrow10]

I have recently purchased a Netgear Nighthawk AC1900 router and now my work laptop (Dell Latitude E7250) won't connect.  It will find the network ok but then says 'windows was unable to connect'.  I had no problems connecting my MacBook or iphone, ipad and tv.  The laptop is running Windows 7. Help!

Welcome to the community, @Sparrow10

What type of wireless security are you using?

Did you try to remove it under preferred networks? Did you try restarting the laptop?

See the article below for additional troubleshooting steps.

Do you mean what wireless security is on the laptop?  if so, then there is none according to my info tech guy at work, it connected to his iphone with no problem.  It also used to connect to my old crappy modem.  I have tried some of the links you sent but some I couldn't get and some didn't help unfortunately. Any other ideas would be great. thanks
