No DNS - Everything else works fine. DNS Set to public servers!?

[Jambo]

In "Fix Common Problems" i'm getting:

Unable to communicate with GitHub.com

In checking for Apps, "Download of appfeed failed." [...] "Last JSON error Recorded: Syntax error"

In checking for plugin updates:

"Checking connectivity...
No response, aborting!"

 

DNS is set to 8.8.8.8, then 192.168.0.1 in the Network Settings page.

I have two ethernet connections going to a single network. Tried each individually and no change.

Tried deleting network.conf and no change.

 

 

The shares, VMs and WebGUI are reachable by my network no problem and the server is plugged into the same switch as my desktop is.

Ok, solved after 12 hours of pissing about.

 

For anyone who comes across this - My Asus router was Spoofing / Extending the TTL. Lord help me.
