I am running windows 7 ultimate on 2 desktops , windows 7 home premium on an hp laptop with a lynksys router wrt160N . setup homegroups on all 3 pc's works fine on 2 desktops and on laptop when wired, but does not work wireless . when laptop is wireless i try to access it , it will not let me run trouble shooting an issue was found ., file and printer sharing resource is online but isnt responding to connection attempts. The description remote computer isn't responding on port 445 possibly to due to firewall or security settings. turned off firewall on wireless laptop still no access. but no problems when wired. How can this be resolved? thank you

Hi, Thanks for the post! According to your description, you failed to connect through the wireless, it still persists even you turn off the firewall. Can you ping the laptop when it’s wireless? How about restart the router? Can you access the laptop using the IP address instead of computer name?
