I am trying to replace a wireless router with a new one. When I set up the new wireless router, I can access the internet on all the computers (3) but I am not able to share files. I have copied all the settings from the old router, turned off firewalls and nothing is working. When I put back the old router, everything works fine.

Any ideas would be greatly appreciated.

Thank you
Bill
