Upload Speed 1mbs

[vrgnmdiausr1]

Hi, I am not sure exactly when this started, the last week at least but possibly a week or two longer (was on holiday but things seemed fine before then), but have recently had horrendous upload speeds of around 0.5-2mbs. I am on the Hub4 with Gig1 package. No issues reported on the virgin issues tool thingy (although I couldn't do it online as it kept giving an error message, so had to do it over the phone).

I've been keeping an eye on it all day, and it seems to be based on early testing, to mostly be an issue approx 5pm - midnight roughly. It was fine basically all morning and afternoon today as far as I could tell. I have numerous hub resets including a factory reset. I have tried a few WiFi devices and one ethernet device (playstation). When things are working download speed has been around 300-450mbs on wifi devices, and 700-750ish on the playstation (I'm not overly worried about the download speed so long as it works). When working upload speed was around 30-50mbs.

I don't think anything has changed recently except obviously a bit more rain and that I have new neighbours, I assume they are on virgin as trying to get BT was a huge pain that would have had to wait for roads to be dug up for etc. when I moved in a few months ago, but I haven't asked them.

I have been keeping the network monitor on in Fortnite (I know, I know), and it shows constant packet loss 10-40% and slow upload speed.

Looking at other posts folks seem to get very technical, sorry I don't know what everything means, so I will post the download/upload log things in a moment. Please let me know what else would be beneficial to get help.

The Upstream channels are struggling - the qam's should all be 64 - they are dropping to 16/32 on some channels and you have T3 errors.

Can you try this
______________

Switch the Hub off and unplug it from the mains supply for five minutes. Whilst it's off, do a quick check that all of your coax and ethernet cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables. Then switch the Hub back on and leave ~5 minutes

When all done, check back in the settings and ensure that the RS error counts and T3 errors have all reset to 0. Also look at the 4 Up channels - are they now at 64qam. Then check every hour or so to see if errors start reappearing - they shouldn't. If they do (particularly the postRS and T3 ones) you have a problem (noise) that only a Tech visit will sort.

Ok thank you very much, I will try this all tomorrow and see if things improve long term!

Right now as I'm posting, having done absolutely nothing, these are my current upstream logs which I guess are what they should be most of the time (again supporting the idea that so far these issues mostly happen in evening time):

OK - evening struggles will be evident on a BQM

If you haven’t already, set up a free, secure and “offlsite” - “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph”.
