Neighbour has 3 computers, a dlink router and a brother wireless printer. All was working until they had a broadband crash. She had to resetup the router. Now, all computers work OK but can't access the printer. I tried uninstalling the Brother software on main laptop. On reinstall, failed with " a firewall may be blocking...etc" Checked Windows F/W off, and turned Norton F/W off - no change. Tried to set-up ptinter from its menu - connection failed. What do I need to set up in the router pages to allow connection please (had a look at them, but nothing obvious jumped out at me). Sorry to be long winded, but trying to answer many potential questions. Thanks.
With my Lexmark I had to give it a fixed IP address through the router (a D-Link) otherwise the pc's kept looking for the old IP address (always the wrong one!). I don't know if this is the same for Brother.
