FurryNutz, this is for you. I tried 1.3 again. I restored to factory settings and thought I would try by setting up the router manually from scratch - not using the config file. Added wireless, added statics, etc., but my ethernet laptop couldn't access the internet. I then reverted to 1.2 and tried manual inputs, again I couldn't browse. Strange thing is that the voip system registered with both 1.3 and 1.2 - I have Freepbx on a raspi, OBI device, and Siemens C470IP. By now I'm getting frantic because it's way past my bedtime and I don't have a clue. I rolled the dice and restored using a config file and everything started working again.
For my learning, can you explain this, FurryNutz? I thought that if I restored to factory settings the router would forget all previous clients. I tried on numerous occasions rebooting my modem and router to no avail.
If I ever wanted to start completely from scratch - wiping the router to what is was in the box when brand new - is there a way?
