I am fairly experienced, with 3 servers currently running. But after a vacation I got back to my office and the Pi there just wont come up on the network. When I did an ifconfig it looks like it is setup with a loop back and a 255.0.0.0.
Since I am pretty sure this is not correct, I went to try to move it to a different wifi network or at least confirm its still setup correctly, but when I loaded the Micro SD into my computer to check and edit the network.txt file, the SD card is read only.
Any ideas? Can I set the Wifi and IP info though the onscreen terminal? I have that up on my office TV. Sudo config didnt look like it had any network settings.
