i can get to the real internet on wifi using my phone in airplane mode, so obviously my linux system has a virus that blocks the internet. sorry for the big alarm. need to archive this thing and eventually figure out how to do incremental backups of a new system.
definitely weird behavior. no route is messing with your route tables - you can view these. odd to get a DHCP lease, and IP, but no route. can you log into the router itself to check logs? can you run a traceroute on the Linux system to see where the drop is? i like to manually set DNS servers, rather than use ISP nameservers. try switching those out. (e.g. 4.2.2.4, 4.4.4.4, 1.1.1.1, etc.) [ but to be fair, this is a routing issue, not DNS, but DNS problems might be up next... ] have you tried turning the router off and on again? :P good luck! best regards, ------ https://unix.stackexchange.com/questions/50098/linux-network-troubleshooting... http://www.ruf.rice.edu/~rlug/help/net-debug.html https://wiki.archlinux.org/index.php/Network_Debugging http://www.thegeekstuff.com/2011/12/linux-performance-monitoring-tools/ https://web.archive.org/web/20160128084542/http://www.linuxdoc.org/HOWTO/NET...
