I am a noob at self hosting. Currently I selfhost a couple of services like expenseowl, npm, adguard and vaultwarden. I just use an old laptop for this.

Right now I am using my adguard both as dns and dhcp server. However randomly I get 2-3 minutes of random fails on my wifi. Meaning internet access is lost which shows on my android phone. I tried to debug a bit. Moved dns from udp to tls or https but random 2/3 minutes of no internet access happens.

How do I debug this?

I moved from udp to https to tls because of delay in dns responses which improved things but did not fix, meaning low occurance but not issue free
