After one of the latest updates, I've encountered a few issues. The most impractical is that when I wake up my laptop from sleep, the wifi reconnects, but none of the services can connect (browsers, instant messaging, email, etc.) The error message I get varies from service to service.
Firefox tells me it's a DNS resolution issue. No amount of restarting wifi, ifdown/ifup etc. will restore connectivity. I have to do a complete reboot to be able to reconnect.
Has anyone encountered this? If not, where do I begin troubleshooting?
