Constant short network drop outs

Hi,

 

For about 2 months now I've been getting about 5-10 network drop outs per day, lasting about 30-60 seconds each.The drop outs affect all devices, including my PC which is connected via wired ethernet connection. Signal colour on the hub changes.Only thing you can do is wait it out

 

I've tried rebooting and resetting hub details, tested all devices on wired and wifi - nothing stops these drop outs. This never used to happen and is really odd - contract ends in December so unless salvagable will be switching ISP.

 

Many thanks in advance.

Re: Constant short network drop outs

Have you checked the 'Check Service Status' at the top of the page ?

If nothing is showing try phoning 0800 561 0061, this will tell you of more local issues that may be affecting your district. Be aware that it isn't a manned line.

Go round all the accessible internal and external co-ax connections and ensure that they are finger tight.

If everything above is OK we need do some more troubleshooting; to start with …

Disable any VPNs that you have running.

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.

Then

 

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 click ‘Check Router 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: Constant short network drop outs

Hi,

Thanks for the rapid and useful reply.

I’ve checked when I’ve had issues and there is never any local internet issue.

I’ve checked the co-ax connectors and all look secure.

No VPNs or anything unusual in use.

Here is my live link:

Re: Constant short network drop outs

Your BQM is probably as good as it gets.

There is nothing in your Hub data that jumps out as a problem and you Network Log is pretty good.

Your Pre & Post RS Error counts are quite 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.
