dns error

[Alisdair810]

All devices reporting connected but no internet. TV works as normal, via ethernet cable, but everything else reports "Connected but no Internet". Devices than can report give a "DNS Error" report.
Mini TV boxes, boosters, anything that relies WIFI is down.
EE BT auto fault detection sees that broadband is working. I have received no replies to requests for help. 
Any solutions?

@Alisdair810 Have you tried just switching the hub off for an hour or so, with Ethernet up and connected no issues on that, are you sure the wireless is up connected but NO Internet data flow...

What hub do you have a BT or a EE one, if new EE then and if it works HELP to 66033 as a text message and wait for EE/BT to get back to you!
