Disconnecting every 12 hours

 

 

Hi wonder if anyone can help please.

 

Since Thursday last week I've been having problems with my internet cutting out, usually after

two reboots of the modem and router the connection is up and running again.

 

I have now determined that the disconnect happens every twelve hours at 7.30am or pm on the dot!

 

I have tried only resetting the router on occasion & also just the modem but this does not solve the

problem, each time I have to reboot both in order to get connected again.

 

I don't think the 7.30 timing is relevant but I do think the 12 hour interval is.

Re: Disconnecting every 12 hours

if its happening each day on the dot im wondering if for some reason ur system is only issuing a 12hr IP address which would be weird and when thats up its not renewing the lease.

Re: Disconnecting every 12 hours

Thanks for the reply, would the IP address change then?  I'll make a note of it now and then

check again after it goes down at 7.30pm tonight.

Re: Disconnecting every 12 hours

no the ip would not change as once you are assigned a new one it will give the last known one bakc to you. 

 

Once it does off can you access the modem at http://192.168.100.1 and post the stats and modem logs. 

Make sure you try this and post the longs before you try and reset the modem as that will clear the logs

Re: Disconnecting every 12 hours

Well just got caught off guard, went down at 7.26pm, four minutes early.

 

Two reboots of router & modem and I'm back up and running, 'til 7.26am no doubt.

 

Couldn't access modem logs once disconnected, no changes showing in logs.

 

Thanks for the replys.

Re: Disconnecting every 12 hours

if you wasn;t able to access the modem logs then its not a DHCP problem as you would get on the modem still.

 

To rule out the router can you try the conenction without your router. connect it an hour or so before the conenction drops and see if you can stay online with a direct connection

Re: Disconnecting every 12 hours

Tried with modem direct to computer, no disconnect at 7.30am.

 

Rebooted and attached router, no internet, rebooted both again and it's now on.

 

So there's a problem with the router then.  I already did a factory reset over the weekend so

do I need to ask for a new router?

 

Thanks again for the replies

Re: Disconnecting every 12 hours

As regular-ish as clockwork, 7.24pm disconnected.

 

Rebooted router twice, with no luck, then modem and router once and now back up and running

again.

 

Join me tomorrow for the next exciting (yawn) update

Re: Disconnecting every 12 hours

Managed to last until 7.34 this morning, one reboot of both modem and router fixed it this time

Re: Disconnecting every 12 hours

I would recommend you leave this post for 2-4 days until a VM tech gets to see it as they read messages by last rely date (oldest first) so posting every 12-24 hours will delay a reply and keep placing your to the back of the queue
