Hi, My Netgear R7000 router keeps loosing Internet connection (wired and Wifi). About 3 times per day. Randomly. I can still reach the router usually, but not WAN. We can't ping 8.8.8.8 anymore So I have to reboot the router and then I get access again. Any ideas? Thanks! NOTE: We did not have any problems before updating to Firmware: DD-WRT v3.0-r33986 std (12/04/17)

Do you mean doing this ? https://www.dd-wrt.com/wiki/index.php/Hard_reset_or_30/30/30 Then do we have to reconfigure everything manually (yaiiks) or we can restore a backup?

For an R7000 telnet into your router and do:

Code:

erase nvram
reboot

And yes put settings in manually Sad

ok! Mmm.. Would be nice to have a readable export or mods file between the default and the custom setup. This way from build to build it is easy to see what was setup in there. Thanks for the tip... see you on the other side if it does not change anything.

UPDATE: So we completely reset the router and reinstalled from scratch with manual configuration. All clean and neat.

The router connection broke again this morning after the total update.

One of our team members thinks it might be related to WAN DHCP Lease Time because the last time it broke, we went to Status_Internet.asp an the Remaining Lease Time was 0:00:00. We just renewed and gained back our connection instantaneously.

Any ideas? Thanks!

Upgrade to newer build, I would suggest reading the build threads here on the forums. More than most likely the latest will work though, that router is still being used by the devs for testing.

YELLOW LOGS

Also, in my syslogs in the interface, two elements are in YELLOW;

Code:

Jan 29 15:27:26 DD-WRT daemon.warn openvpn[1199]: NOTE: when bridging your LAN adapter with the TAP adapter, note that the new bridge adapter will often take on its own IP address that is different from what the LAN adapter was previously set to

Thanks all!

Posted: Mon Jan 29, 2018 22:05 Post subject: Time

The time is a bug. The log is based on UTC and the router starts an NTP client after. The router then gets set to what every timezone you set in the GUI but the syslog daemon is already started by that time. It is all because of the boot order.

Hi, Thanks for your replies.

Quote:

TTRAFF is also known to cause bugs and drops in some later builds. Not sure which ones are affected though. Disable it.

I disabled WAN Traffic Counter / ttraff Daemon ... will see if it helps.

Quote:

When you get a DHCP lease from the ISP, how long is it for?

Not sure how to get the ISP DHCP lease time setup. Any command for this?

Quote:

Does it appear to be constantly renewing itself over short periods of time?

When this happens
- I can connect to the router Web Interface with http, but not https (https times out).
- I cannot SSH into the router.
- I cannot ping any other IP than the router. (Any other LAN on WAN IP is returning Request timeout for icmp_seq.

- As soon as I go to /Status_Internet.asp , I see this:
https://www.dropbox.com/s/garlku1rwcm5dyu/Screen%20Shot%202018-02-05%20at%2008.39.01.png?dl=0

-I then do a DHCP renew... everything is back on track and I get this:
https://www.dropbox.com/s/z7y2sjzhhbwnn3q/Screen%20Shot%202018-02-05%20at%2008.39.55.png?dl=0

Sometimes I click on DHCP renew again, and the lease time will be or 1h, or 1 sometimes day. Weird

Here is the System Log from yesterday night event when it cut itself out. Please note the YELLOW and the RED elements:
