Yes that's it, if you sync at that and can't get that with a speedtest then try a different computer and cable.
Wow...
Well, this is a newish build 3 floor town house bur far from big, walls are all plasterboard, I haven't found a brick yet.
Router is on the middle floor, wired into (I was wrong) a 500mb powerline socket.
Here's the range of results...
Wired PC (via powerline) 21mb
Laptop downstairs but not underneath router under 20mb
Laptop on wifi literally 6 inches from the router 45mb
Phone wifi next to router 40-45mb
Laptop on wifi approx 2 meters from router with only the arm of a sofa in the way 30-35mb
Wired laptop to router 55mb
That seems really temperamental to me? In the old house I was using a BT Homehub and I got a stable wifi speed all over what was probably a bigger house in square footage terms?
I'm annoyed that the Sky Q mesh network (I have 2 mini boxes) seems to be doing nothing.. can't remember how well that was configured though to be fair. However I do have a load of smartthings/hue/nest products around now, clearly they're not slowing things down given the wired results but could they be interfering?
Is it normal to lose 20% by not being on top of the router?
Also.. on the wired powerline.. is that level of loss normal? Would getting gigabit ones help resolve that?
I'm actually both pleased I'm getting what we paid for and frustrated this seems like a fiddly complicated fix.
