My 7900 has been happily working on the network for quite a while. Then I installed a new router (to get better wifi range) and I cannot print. The problem, I think, is that the printer driver has the printer at 192.168.1.109 while the EpsonNet Config says the printer is at 192.168.1.108. I have tried setting the printer IP manually to 192.168.1.109 but that doesn't help - then EpsonNet says the printer has no IP address. The network works fine other than this problem. Thanks for any suggestions - I really need to make a print today!.
