Loss of ipv6 on wifi network #2270

Open alviss7 opened 1 year ago

alviss7 commented 1 year ago

Hello,

I've noticed that once a day my phone loses its ipv6 addresses on wifi only. To recover an ipv6 address, I have to put my phone in aeroplane mode and remove it (Pixel 6).

My network uses SLAAC for automatic ipv6 configuration and the preferred lifetime is 1 day. If I increase this value to 4 hours, I find that my phone loses ipv6 more quickly (after about 2 hours).

I managed to do a logcat during the ipv6 loss but I don't think there's any useful information:

I'm not sure what I can do to help you find the root of the problem, but if there's anything I can do.

Hi, I have the same problem. Loosing IPv6 address after about 15 minutes in wifi (german telekom speedport smart 4) unfortunally, I cloudn't find useful information about the ipv6 configuration from the router. Maybe the information helps, that someone else (me) has the same problem.

thank y

Could this be a firmware problem? https://issuetracker.google.com/issues/241959699

I experience the same in my home network. Set the MaxRtrAdvInterval to 60 s, as annoying and wrong as this feels...
