I have followed instructions - rebooted the router twice. Upload speeds have increased, however the download speed is around 95MB. This is below the amount specified for the M350. I contacted VM via twitter, they advised me to put something on the community forums here.
I can connect to the internet no issues, however the speeds are very slow indeed. VM checks seem to suggest a router issue. All wires are correctly placed in the router and socket - they are not loose etc. Oh and by the way I am less than 20 feet from the VM cabinet in the street
I have just posted this on another thread _______________________________
If you think that you have a BB speed problem, then to check the speeds coming in to your Hub properly, and whether they match what you should be getting, you cannot rely on wifi tests, - no BB supplier guarantees those - only speeds "TO" the Hub are guaranteed. So, can you test speeds directly like this. If you expect >100Mbps then connect a 1GB enabled computer/laptop, with up to date drivers, via a NEW and working Cat5e/6a ethernet cable (old one do fail and drop back to 10/100 connections).
If they are still low – boot your device into Windows safe+networking mode - to disable any potentially interfering software - and try again.
There are many posts on here (I have a list of ~30!) where QoS software, unknown/flaky software, old network card drivers, corrupted browsers, bad cables or other connected devices are limiting speeds on tests.
Report back what that gets.
