Can connect to home WiFi with phone but not PC

This is doing my head in. The PC is connected to the WiFi network but no browser will work - it doesn't time out but just endlessly tries to connect without success. However, I am posting this on my phone, connected to the same network, mobile data is off so it's definitely using my router. What's going on? Tried Firefox, Chrome and Edge, none of them work. I can send/receive for POP mail no problem.

Thanks

EDIT: sorted (for now anyway). Trusteer Rapport was going a bit bananas. Ended it, rebooted and all ok.

Yeah, gettin on a bit I like Outlook, it has a good interface and works for me, so I use a POP server. Hushmail is very good and has webmail as well if I need it.

You don't mention your OS

Try the following

1) Power cycle your router and computer ( be patient with the router )

2) can you logon to the router from the computer?

3) Can you hard wire the computer to the router?

4) Look in the device manager are there any devices marked disabled?

He sorted it, see his edit in the first post.
