Welcome to the Community and thank you for getting in touch.
I am very sorry to hear you have been experiencing issues with your upload speeds since moving home.
I have taken a look from our side and they does appear to be some issues flagged with you in home network. This means our system has detected some stability issues with the WiFi connectivity to some of your devices.
When you are run the speed tests, are you doing so on both wired and wireless connections? If so, can you please provide the results for both?
Please let us know and we will be happy to investigate this matter further.
If I could just respectfully suggest to the forum staff that the answer might be in posted hub status data, for which I've already escalated this post. It's got nothing to do with time of day or "wifi stability", and everything to do with:
1) Poor SNR on D/S channels 2 and 3 that looks like a noise ingress issue.
2) D/S power levels that are all over the shop, with a range that's too wide, and neither level nor properly sloped across frequencies.
3) Only one U/S channel when there should be four.
4) The hub is screaming it's head off at 54 dBmV trying to remain in contact with the CMTS over that lonely U/S channel .
5) And all of those problems show up in the appalling network log that stuffed full of repeated downstream channel loss errors.
I daresay a reboot temporarily fixes that and makes the status briefly look OK on casual inspection, but that won't fix the problem which is a noisy connection and possibly an improperly setup or failing amp at the street cabinet. If a technician appointment could be booked for @Vid123 then I'm sure they'd appreciate it.
