Upload speed

Hello, 

Our upload speed is very bad. We can't turn our camera on during a video conference call. If we do it disconnects us. We are paying for 5mbps upload speed but we are getting below 1mbps regularly since wednesday as we test it every day on speedtest.net. Sometimes it's closer to 0mbps. We have not changed anything and tried restarting the router. Our device is a new laptop - all up to date. It was installed about 6 months ago and was all good until last wednesday. Download speed is fine. My question is why is our upload so bad all of a sudden and could someone fix it, please? We didn't get any real help on the phone.

Re: Upload speed

Can you please

Type 192.168.0.1 (192.168.100.1 in Modem mode) into your browser URL bar and press enter. 

Hub 2 & 3 When the page appears DO NOT LOG IN but click ‘Check Router Status’.

Hub 4 When the page appears LOG IN then Advanced Settings > Tools > Network Status.

Copy and paste the contents of the Downstream, Upstream, Configuration and Network Log tabs onto here, if you get a yellow / straw box warning click the Post button again. Use one post for each tab if you wish.

Please do not use screen grabs.

A Guru will be along soon to decipher the info

Re: Upload speed

Anyone able to tell me if there are any obvious problems, please? What do I need to do? Still very low upload speed and download speed isn't the best. Thank you

Re: Upload speed

Two of your Upstream Power Levels are maxed out.

This will need an engineer to put right.

You can either call in (08:00 is the best time) or wait on here for a few days (6 to 10 days average) until one of the VM Forum Staff comes along.

If you wait on here Do Not bump the thread it will put it further down the VM 'to do list'.

Also your Upstream Speeds are quite low for video conferencing especially in HD or if other applications are also using your bandwidth.

TBH, I hadn't realised that 50Mbs contracts were still in use.

Try a reboot to see if the Hub can renegotiate a better connection using this method ...

Switch the Hub off using the small switch on the rear of the Hub next to the power cord and pull the PSU plug from the wall socket.

Give it a good 5 minutes put the plug back in and switch the Hub back on.

Allow the Hub a few minutes to fully restart then try your connection again.

Re: Upload speed

Thank you for your help. I've done that but it is still the same. Hopefully the VM staff will notice and arrange an engineer visit to fix it. I will also try calling them in the morning to see if I can arrange an engineer visit via that route any quicker.

Re: Upload speed

Hello again. Could anyone help us? I see that some people's complaints are looked at faster than ours and we posted sooner than them. Why is that the case? We just would like to get back to normal upload speeds as we are on zoom very often and is one of the main reasons why we got virgin fibre internet.
