My fibre plus speed yesterday (16th Sept 17) dropped from 77 Mbps to 10.8 Mbps the upload speed is 15.6 Mbps. It is is the same today. The router is a Hub One new in June 2016. These are taken on a pc connected directly to the Hub One.
Could PlusNet staff please check what is causing the problem.
Fixed! Go to the fix.
Re: Fibre speed down from 77 to 10,8 Mbps
You could have a look at the numerous other posts from people with similar issues. Seems its a nationwide problem affecting lots of other ISP's as well as PN. Most are back to normal now though.
I have now checked the speed after the post and it is now back to normal. Earlier today I made a similar post on PlusNet Feedback so it may have been fixed from there.
