Recently my internet connection became very unstable - it was not working for days.
I spoke with my provider (init7.ch) and they told me that there might be a problem on my side:
I was also able to determine that your router successfully sent a Discover on 15.09. at 15:15 and again obtained an IPv4 address, unfortunately I also had to determine that the router has since sent out more Discovers. Therefore I still believe that something is wrong with the router.
A Discover is sent out as soon as the router reboots or has no IPv4 address for a longer time.
Normally it should send a Discover 1 time and then only send requests to extend the lease.
I’m wondering how I can check what DHCP requests does my router sends to provider. In logs I can see DHCP events related to local network only…
