Here's my configuration/situation: Home LAN. 2 Windows 7 PCs. 1 Macbook Pro OS X Snow Leopard. 1 NEW WRT610N Linksys router. Connections are: 1 Win 7 PC wireless. 1 Win PC wired. Mac wired. Before I changed the router out from old D-Link G router, all computers could see everything. I "upgraded" to new Linksys N router and now the Mac can browse to ("see") the 2 Win 7 PCs BUT the 2 Win 7 PCs can no longer "see" the Mac. I can however ping the Mac from them both. Hope I can get the experts to solve or refer me to someone who could.
