Speed can drop to very very low levels

[Tom_F]

Hi javedsaleem, thanks for posting.

Sorry to hear about the problems you've had with slow speeds. I'd like to take a closer look into this to see what might be causing it - please get back to me via PM (the purple envelope icon) so we can investigate.

Tom

[Tom_F]

Thanks for your reply @javedsaleem - I've arranged an engineer visit so this can be looked into further. You will find confirmation of the appointment via your online account (virg.in/myVM) and can reschedule from there as well if needed.

Please let us know how you get on, or if there's anything else we can help with.

Tom

UPDATE

Things have improved, however latency is high. The Router is new and the Power from the VM Roadside box is high. The only outstanding thing is probably the cable from the VM Roadside box, to the Hub. It was installed in the days of ntl !!.... or it could just be internet traffic.

The Speed Test on a Chromebook, wireless connection is 261mb download, as below.

The Network stats are below:-
