My desktop had to be cleaned of malware recently. The desktop was the host for the modem and router. While the desktop was out, we continued to use the wireless laptop. Now that the desktop is back I can not stay connected to the internet on the laptop unless I unplug the modem for two minutes then plug it back up. I also can not see the shared printer on the laptop so that capability is gone as well. I tried to reset the home networking but that did not correct the problem. Do I need to disconnect the firewalls on both computers to get internet and shared printing? Any help would be appreciated.
