[sane-devel] Newly installed cable modem caused loss of wifi scanner connection

[guy]

I'm trying to help a neighbor, I have basic user level knowledge of 
Linux, he doesn't have any.
I installed Linux Mint 17 on his Dell Laptop and successfully installed 
his wireless HP Deskjet 3520 Printer/scanner. The scanner has worked 
well for about 4 months.  The other day his cable provider installed a 
new router, I was able using CUPS to install his printer but Simple Scan 
and Xsane do not see the scanner.  I assumed its do to a change of IP 
address.  However, I cannot find any facility for checking the IP 
configuration setting.

I look forward to any suggestions in resolving this lack of connectivity.
