I have been using my Linksys router for some months to allow access to the internet through for the three computers on my home network and this has worked fine. Recently I have set up file sharing between the three computers and whilst I have been succesful in establishing the connections initially I am experiencing regular losses in connection. There appears to be no pattern to the breakdown in the connection. When I try to access the network I receive the error message "..... is not accessible. You might not have permission to use this network resource. ......" "the network path is not found" The internet connection continues to operate normally. I am running Windows XP & I have run through the filesharing troubleshooter without success. I don't know what to do next! Any ideas?
