Blue light but no internet

[#1]

Help!

I hope someone can help me. I have a blue light on my router but no Internet. It occasionally goes orange with a red flashing b, but then seems to go blue as if everything is fine. Have tried test port and no change. Not sure what else to try and if the problem is my end or plusnets end. If anyone has any thoughts I'd really appreciate it.

Is the broadband username correct?

Log in to the Hub One by using http://192.168.1.254 in the address bar.
Username and password are located on the router - it will be admin
Once logged in go to:
Advanced Settings > Broadband
what is Broadband Username?

Thanks for your reply. Username is [Removed] - I'll try that when my husband gets home as I assume I need to connect a laptop to the ethernet to connect to the router. The funny thing is it came back on at about 4.45pm and has just gone off again - same blue light but can't connect.

Surely this issue isn't my end if its connecting intermittently?

You can check it over WiFi, don’t need to have Ethernet.
That said if you have connected it might not be the issue I was thinking of.

If you have a corded phone you can do a quiet line test to see if there is any crackling on your line (no filter) ring 17070 then option 2 for the official quiet line test.

Or you can go to https://faults.plus.net and it will run some basic trouble shooting on your line (can do that on mobile data)

Thank you, sorry for the delay in getting back to you. Could only see the router settings when connected via ethernet, I did try wirelessly but wouldn't load the page. Username and password all looked fine.

We don't use the landlines so don't have a phone to test it unfortunately.

Have run through the steps on the link yoy sent, nothing worked so have now raised it as a problem. Incredibly frustrating as I work from home! I'm at a loss.
