Internet keeps cutting out every couple of minutes for about 30 seconds.

Any help with this or anyone experiencing the same.

 

Never had it before, but every 1-2 minutes my internet just won't connect or is extremely slow for about 20-30 seconds, or disconnects from a game or voice chat. Then its back up and this just repeats. Been happening since around 5-6pm UK time.

Re: Internet keeps cutting out every couple of minutes for about 30 seconds.

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.

While the Hub is powered off go around all the accessible co-ax connectors inside and outside to ensure that they are finger tight.

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: Internet keeps cutting out every couple of minutes for about 30 seconds.

On a wired or wireless connection?

Have tried resetting and I don't get any joy from that. 

The hub is wired and I have tried both wired and wireless to the desktop and neither seem to make a difference

Post the network, upstream and downstream logs from the hubs admin pages back here as text

Re: Internet keeps cutting out every couple of minutes for about 30 seconds.

Your Downstream Power Levels individually are all within spec but, the differential between the lowest at -6.5dBmV and the highest at +0.7dBmV is too great.

You only have three Upstream Channels, you should have four.

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'.

Re: Internet keeps cutting out every couple of minutes for about 30 seconds.

Okay I will see if I can get someone out, out of curiosity would this just happen randomly there is no specific reason for it? As it has been fine for as long as I can remember and then literally all of a sudden this happened.

is there a cause for it?
