Will Not connect to radio

I received my 6300 on Friday and it worked great using ver .17. I got the urge to upgrade to .21. Big Mistake. I screwed that up royally. Following the instructions, I wiped the table clean and reinstalled 6.21.  I did erase the vsp drivers.  I have Cat 1.6.21, DAX 1.6.21 and my client software also 1.6.21, so I think I'm on the same page all the way around. I was getting a bad ip address (169) instead of 192. I switched from wifi to a wired ethernet connection and that has been resolved.  I bring up the window,the radio says "available".  I tried many times to connect with no joy.  I had found a couple earlier posting with same or similar problem/  Tried their solutions with no luck. oh Yes, I have reset my router a number of times also. What am I missing?  Probably something simple that I will hang my head in shame.
