Well... thanks MichiganTelephone. I had not realized, when I wrote my original post, that I could update directly at the OBiTALK portal and I have now done that. Therefore, I am not now concerned that I can not connect to the Web portal. If I find, in the future, that I do need to connect through that portal, and my browser will not access that 192.168.1.2, then I will try your other piece of advice (switching computers).
By the way, instead of me opening up another new post, I could ask you -- If I take the OBi110 off of my network where is it presently installed (my home network) and install it on another router in a different network (like at an office) do I establish a new Obitalk account or just go to that present OBitalk dashboard and make some adjustments there?
