Very slow upload speed

Hi,

I'm connecting via ethernet and have started getting very slow upload speeds.

Download is fine as can be seen on the Speedtest screenshot below. 

Router Stats pasted in below. Superhub 3.

I'm in the HP4 area. Is there a know problem which could be causing this?

Thanks

Brian

  • Downstream power levels out of spec (-6 to +10 is in spec, 0dB optimal).
  • Upstream power levels are very high.

You need an engineer visit to correct the power levels at the cabinet.

Re: Very slow upload speed

Thanks.

If I've understood correctly the problem is at street rather than house level? If that's the case how do I request for an engineer to adjust the power levels in the cabinet?

Unless you've got one of these devices fitted between the HUB and cable to the wall socket there is nothing you can do yourself to fix it:

Yes the engineer would have to access the local cabinet and adjust the power levels from there.

You'll need to contact VM to arrange this.
