Constant Disconnections and packet loss

Hi

I have been experiencing constant issues with my hub for the last month. This is after 3 days of uptime since the last reset. Could anyone advise what I should do as working from home is becoming very tricky!

Thanks!

Re: Constant Disconnections and packet loss

Your Pre & Post RS Error counts are very high.

In an ideal world they would be at zero and stay there. To zero them can you reboot the Hub using this method and then keep an eye on the counts.

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 check the counts again in an hour or so.

Re: Constant Disconnections and packet loss

Can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you should post the link straight away.

Post a 'Live Link' to your BQM on here.

Instructions for posting BQM Link

Under your BQM graph are two links in red.

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 in the ‘text to display’ box write My BQM then click OK - you can post the link straight away.

Re: Constant Disconnections and packet loss

Your >> BQM << is showing that you have been hyper busy uploading and downloading or you are in a very busy area that is verging on over utilisation.

You can phone in and complain about the Constant Disconnections and packet loss (08:00 is the best time) or wait on here for a few days (6 to 7 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'.
