This problem only started happening about a month ago. Ill start up one of my PC's and all of my network shares would be up and shareable. But after about an hour they will disappear. This happends on 3 different computers of mine and i switched over to my linux os and it happends there too. So this obviously is a router issue, which doesnt make sence because no settings were changed in the passed 4 months. my wrt54gs is running alchemy 1.0. Everything else works fine, its just really anoying to have to keep restarting my computers to have my workgroup shares enabled. Thanks for any help!!
