Thank you for the responses. Google was only temporarily blocked, and only on my home network. It was never blocked on the tethered cellphone. There seems to be more. I’m not a programmer but thought page faults, debug traces, kern.err, and SIGSEGV messages were signs of problems. I’m just not sure how these message may affect operation. I’ve attached a snippet of the log containing the messages.
Configuration: internet via phone connected by tether (USB), one wireless client, one wired client. No VPN, no TOR.
