Hi all

So i got myself a R7000 and loaded dd-wrt on it. Its connected to a TP link modem which is bridge to the R7000.

Now most of the time it work fine but from time to time i keep losing internet access and i dont know why.

Wifi still works fine and i can access NAS drives but the internet seems to die.

The modem shows no errors itself and seem to hold up it end f the connection but something between the modem and the router is not agreeing and kills the connection.

Im fairly new to dd wrt and with so many options don't really understand what it could be etc etc.

I have just turned syslog on as it wasn't at first but is there anything i should be looking out for or anything that would cause such issues.

Many thanks in advance

What ddwrt version have you flashed? Have you done an erase nvram?

Hi

I followed this guide

http://www.tweaking4all.com/hardware/netgear-r7000-dd-wrt/

DD-WRT v3.0-r30700M kongac (09/27/16)

under administration under commands

In startup it has this

ifconfig `nvram get wan_ifname`:0 192.168.2.2 netmask 255.255.255.0

in firewall it has this

iptables -t nat -I POSTROUTING -o `nvram get wan_ifname` -j MASQUERADE


My modem in at 192.168.2.1

As i say it seems to work but then every so often seem to have a little wobble and a few minutes later is ok again.

The modem has no errors and holds the connection.

The syslog doesn't bring up anything either.

Under Administration - commands execute
erase nvram && reboot

This will reset everything. Try just setting up the basic like wifi security, channels and not much more than that. Test it a few days to see if that works for now.

are you using wifi scheduling? That caused something for me. Apparently in some older builds the router would crash X (for me it was about 30) minutes after wifi scheduled to turn off

Can you give the latest <Kong> build a shot, and then observe the log with it running?

Located here: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=306845

You can also from the command line interface, type "ddup --flash-latest" and update to the latest <Kong> and see if that resolves things for you...

Hi all.

Im getting this again.

It happens most nights about 8/9pm onwards.

Last night i flash lastest stable firmware and then unplugged it and left it in a cool spot overnight.

It has a cooler underneath it which i thought may help it but it still seems to do it.

On my modem the log says "lan 4 link down" then "lan 4 link up" which is the link to the R7000. The modem is working fine so its not that. It seems the r7000 is restarting or something

heres the latest log when it happens

It then starts repeating this time and time again.
