Very slow upload performance

Beverley80 — Wed, 03 Jun 2026 10:09:03 GMT

We're getting very slow upload speeds from our Sky Broadband Superfast 35. Using a WiFi SpeedTest app on an iphone next to the WiFi router these are the specs I'm seeing:

upload speed, download speed, ping ms

10:58am 0.4 , 13.8, 91ms -- all other devices off
10:57am 0.4 , 12.3, 14ms -- all other devices off
09:55am 0.7 , 11.0, 405ms
09:57am 0.4 , 14.5, 15ms
10:46pm 0.4 , 13.4, 42ms
08:03pm 0.4 , 11.0, 14ms

I've restarted the WiFi unit without any performance change. I disconnected all the other networking devices before issuing the latter 2 tests. I can't understand why the Sky tests claim the unit is working well.

@Beverley80 thecspeed of your connection overca copper phone line dependsxon the length of the line to the fibre cabinet and from your download speeds it is very long. If you have a black hub as I expect you do if you post your hub's stats it should be possible to see what the position is see Sky Hub statistics

Thanks for replying

Unfortunately my response with the hub's statistics seems to have not been received, and I'm not at home to try it again. Maybe the webpage timed out? Basically, it showed 0.7Mbps upload performance, although the evening before the hub could barely stream a movie. Maybe it's weather related? We were promised for a techie to come around to the property within 3 days to check its performance, but no-one has rung.
