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.

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.

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.

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

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.

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

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

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
Join me tomorrow for the next exciting (yawn) update
