Network left in oddly broken state after disabling and renabling in Network Preferences

[pakyr]

After disabling then reenabling the Wifi and reconnecting to a network, the connection is in a very odd broken state. Network preferences shows green/connected and that the machine has an IP address, as does the applet in the deskbar (after relaunching, as it seems to crash when I do this). However, pings fail (including to ip addresses so I assume this isn't a DNS issue), and I am unable to navigate to new websites. Bizzarely enough, however, if I already have a website displaying, I am able to continue browsing on that website only. It is not some sort of cacheing; I am able to navigate to pages I have not been to before (like new threads on the forum), as long as it is on the same domain/subdomain. Similar behavior occurs if I toggle the hardware switch on my machine to turn off then on again the Wifi card (an Intel 7260).

Not totally sure what is going on here, but I have included images of the described behavior (all taken in the same session after disabling/reenabling the network), as well as a syslog. Please advise if anything else is needed.
