Is a Linksys router a good enough firewall that I would not need ZoneAlarm or the windows firewall enables? My Linksys is model BEFW11S4, 2.4 ghz 4 port. Last night I could not reestablish internet or email after 'updating' my ZoneAlarm free version. I uninstalled ZoneAlarm and this morning I'm back online. My charter cable tech told me this router acts as a hardware firewall and I'm just looking for confirmation. TIA for any thoughts!!! katy
