Turns out I was too optimistic. wicd and the little adjusting I did does not deliver a working Internet, not every time. Today, no matter how I tried, I couldn’t connect (beyond the router, to which I can always connect) until I changed the laptop IP from dynamic to static, and the DHCP client from automatic to dhclient. All of a sudden, I was back surfing!
Only, just now, when I booted up the laptop again, I couldn’t connect beyond the router (which connected fast enough), not until I changed the IP back to dynamic… This is seriously weird and I can’t explain it. I wonder if it’s got something to do with my router, an instruction that is lost on the way, DNS services that aren’t updates… something?!?
WiFi on Linux is NOT easy.
