On a LRB20, Router Firmware Version V2.6.4.2 , located in europe
Connected to a fiber modem with a LAN cable LTE deactivated
Issue:
The router emits a wifi signal without Internet
Devices like mobile phones or laptops have wifi connection but no internet connection
Timelines:
Issue happens Approx twice a day, since 4 days
We had a year without issue, the issue occured without clear trigger
Workaround:
Reboot the router solves the issues
Actions done so far:
- Rebooted the Fiber Modem
- Full reset of the LBR20 router
- Deactivated beamforming, Mu-mimo and fast roaming
- checked logs but the only go to the last reboot, so no tracks of what happened before the reboot
- Checked router and satellites updates
When this situation began, people soon discovered that the apparent problem is the Orbi stops resolving Domain Names into IP addresses. When they would 'ping' some place by IP, it would work. (for example 1.1.1.1 or 8.8.8.8 succeeds) But, when they would ping by domain name, it would not. (one.one.one.one or dns.google fails) Early attempts to find a solution centered on how to move DNS resolution off the Orbi (set up a separate DHCP/DNS server, log into via telnet and restart the dnsmasq process, create a script to constantly reboot the process). Some people discovered that removing the "Automatic adjustment for DST" worked. Then, Netgear engineers announced that Traffic Meter was the root cause.
With no DNS resolution, almost everything fails to work.
The next time your system "drops", can you experiment to determine if DNS resolution is failing?
