Why it’s the L7780 that is the cause of the Linksys problem
If you use wireless network wizard to connect the L7780 to your Linksys WRT54G router, it will CRASH the printer.
BUT if you connect the printer to your computer with an ethernet cable, and THEN set up wireless networking, it’ll work FINE with the router!
This PROVES that the problem is NOT with the router.
Now, here’s the fun part.
Restart the router.
The printer will freeze, and require a restart to factory defaults which, again, takes over 30 minutes and wastes TONS of ink.
