Fvs318gv2 connectivity issues

I don't think they did.  But I haven't looked at any linksys products in quite a while now.

Yes, it would be nice if your 318s worked like they should.  They are quite nice for what they are when they're up and running.  

We used to have some bandaids in place to keep our rv016s up and solid (script to reboot them every 24hrs).  We had the same script on our old fvs114, but then had to step that up to a hardware rebooter.  Luckily the 114 rebooted in literally a second so that wasn't that big of a deal.  Once the 114 wan port died, we put a spare rv016 in its place while I searched for a real solution.  During that time, we ran across a great deal on some nib 318Ns and got those.  Finally switched out the fvs124g I was using at my endpoint with a 318 as a test.  Initially it was super-painful (just like you're going through now), but once it was up and solid, it was great.  We installed another 318N at a new location, and again setup was a pain since dhcp was an issue on the firmware we were on.  But a firmware upgrade later, it was up and solid too.  Then we replaced the rv016 with a watchguard and sold off the businesses where the rv016s were so they came back as spares.  I've taken a rv016 overseas to quickly build a tunnel when I need one, but other than that, we've just have them, one 318, and the fvs124g as backups.  We still have the 114 and we might put that in place as a switch where we need one.  It's amazing how long of a life networking equipment really has.
