DHClient stops suddenly? WAN-Connection down a few times a day

[Bytechanger]

Hi,

first all works fine, but now, I see suddenly dhclient stops working some times?
I can´t see a reason for this...

When I reload Interface it gets same IP (ipv4 and ipv6) from WAN-site...

Hi !
Did you find a solution to you issue ?

I'm not sure I have same issue, but I recently noticed that my backup WAN gateway (second WAN) sometimes appear down in opensense.
A simple DHCP release/renew (interface/overview menu) is good enough to get the gateway back to green.

my backup wan is a LTE router set in bridge mode.

[Raketenmeyer]

Same here with Vodafone. A simple release/renew or saving the gateway config without a change brings it up again.

[GiantJack]

Yes, I confirm : saving gateway settings and apply (without any modification) bring it back alive 

[GiantJack]

Does anyone has a solution or workaround for this?
