Upload Speed Fluctuating

[midgetgem77]

For about 2/3 weeks now I've had issues with my Upload Speed fluctuating, it sits comfortably at 10mbps on a normal day but then we're having frequent days were it just fluctuates none stop hitting as low as 1mbps and sitting around 3/4mbps. My son is a Twitch Streamer and has not been able to stream these past three weeks without the upload speed just dropping causing immense lag, delay and massive frame drops in his stream.

The Download Speed is okay, this sits at around 90ish mbps and doesn't seem to change, it's only the upload speed which is massively fluctuating.

Post up your Hub/network connection details and someone will check to see if there is a problem there. 

In your browser’s URL box type in http://192.168.0.1 (or http://192.168.100.1 - if in modem mode) (DONT click these links) - and hit return. On the first page up dont login (unless you have the Hub4/5 - when you do login) just click on the “router status” icon/text at bottom-middle (Hub3/4) or top/right (SH’s) of the Login page and then Navigate to these “pages” and just copy/paste the normal “Formatted Text” (not images) 3 FULL sets of data onto here – 2 tables from the Downstream, 2 from the Upstream, & the Network Logs page. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again. If character limits are “exceeded” - just do two posts

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”. Click the lower link (Share Live Graph) then click generate. Copy the text in the Direct Link box, beware, there may be more text than you can see. On here click the Link icon (2 links chain to the left of the camera icon) In the URL box paste the link you copied and then click OK

Thank you for your reply, I've taken these results on my sons PC which is connected via Ethernet Cable.

Nothing to comment with those stats or network log.   A BQM would be handy to see

[jbrennand]

Stats all looking good to me. Post up the BQM link as soon as it develops that might be more informative

Is your son connecting on an ethernet cable to this PC? First thing I would suggest is to exchange the ethernet cable for a New Cat6a one and see if that helps. These have better shielding from crosstalk and interference.

Also basic stuff like, checking all of your coax 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 damage, kinking or chaffing, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables.

A Hub pinhole reset would do no harm either - like this.... first make sure the 2 passwords on the Hub sticker are still there and legible first ! Disconnect any ethernet cables from the Hub (leave the coax connected), and then with the Hub still "switched on" throughout, press pin in firmly with paper clip/SIM tray tool or similar "thin thing" and hold it firmly for at least 60 (a timed sixty) seconds, release the pin, leave for 5’ to stabilise - dont manually switch it off at any time.

Note that all passwords/SSID's will reset to those on the sticker so you may want to go in and change them back to what you want. See if that helps

Someone else should comment soon hopefully with more ideas.

So we managed to get 2hrs of it remaining at 10mbps Upload Speed just for it to once again start Dropping and Fluctuating once again. I will post the URL below and also a screenshot of it at it's current status.

BQM not looking great so far - will need 24h to see the full picture.

Are you in modem mode? What devices do you have connected to the Hub on ethernet cables ?

[midgetgem77]

No I'm not in Modem Mode, there are two devices connected to the hub via Ethernet Cables: Desktop PC and a PlayStation 4

Whilst waiting, see whether VM acknowledge whether there is a "known issue" by trying these options.

Try the “check service,”Area status webpage" (link at top right of this forum).

Also try the “free & automated” Service Status number - 0800 561 0061.

This usually gives the most up to date info. and tells you of more local issues down to postcode level. These may not be listed on the Area Status web page (Areas are not “Geographic” they are billing areas) as that usually only covers faults affecting 1000’s of customers) so phone may give you more info
