Re: Router randomly reboots

What Hub model is it and what do the various lights do when the drops occur?

When did this start happening ?

Also, have you checked for “known network faults”?

As well as trying the “check service,” Area status webpage" (link at top right of this forum), also try the “free & automated” Service Status number - 0800 561 0061 - which usually 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, but even that wont cover problems affecting just a few customers.

Re: Router randomly reboots

Started a week or so ago. No area issues. Test on router was fine. Hub 3 Router goes from white on light to flashing green 'start up' routine for a few minutes. Lasts a few hours then same again

Re: Router randomly reboots

It’s rare it power cycles itself but loses connection instead.

Do wired connections drop out as well?

A bit more information is required, please post the following ...

Please do this before posting the Hub Data

If possible 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.

Please post a 'Live Link' to your BQM on here straight away.

Instructions for posting BQM Live 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: Router randomly reboots

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) and hit return. On the first page up [there should be no need to login if you have done so before unless you have the New Hub4 when you do] click on the “router status” icon/text at bottom-middle of first page up and then copy/paste as “Formatted Text” (not images) 3 FULL sets of data onto here – 2 pages 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.

Also... post the link to BQM
