Just tether a mobile for a short period of time. Or arrange to work from somewhere else for four weeks until your internet is sorted.
@LackyT thanks, so one end rj45 or both ends?
With Hyperoptic though my ping seems to be exactly the same to all the same servers when I was on BT. So I'd assume that Hyperoptic take their fibre cable all the way to the local BT exchange building and from there they connect to BT's main/national fibre cable.
It will be, if you're in Manchester - anything you ping will almost certainly exceed 9ms because all your traffic will have to go down to London and out through LINX, the only way to get a very low ping is to live in London,
I had hyperoptic in Southwark for 3 years and my ping was 0.8ms lol but in reality, there's absolutely no difference whatsoever between a ping of 1ms and 30-40ms, the input lag from your keyboard and mouse, and to your monitor will be around 25ms, so I wouldn;t worry too much
I respectfully disagree; Hyperoptic peer at IX Manchester, where connections to the BBC, Virgin Media, Akamai, Janet and a few others besides are present.
This means I've seen pings to Manchester University of 3msec, rather than the ~20msec that it would take to go via London and back
So it's not all bad!
Getting a 1GB connection and then connecting it via Powerline is a terrible idea. You'll loose a significant amount of speed.
If you're going to run everything over Powerline or wireless then you may as well save some money and select one of their slower options.
If you really need to minimise latency, it might be better to just bite the bullet and run one ethernet cable from the entry point to your living room (you can always clip it along skirting boards and paint it, etc) and put the one router in there.
