Cable wan interface not coming back online, help
-
OK at first we had a 2440 installed on site. We were having tons of issues where if the cable Internet went down for whatever reason, when it came back up pfsense would not see it. I spoke with pfsense tech support that eventually said it was their device and to ship it back. I shipped it back and they found nothing wrong. During the shipping time I needed a router so I turned one of their brand new systems into a vm pfsense and it is doing the same thing. The cable company has came out numerous times and switched the cable modem twice, although they keep using the same brand and model sMc cable modem.
I took that same 2440 and installed it on another clients site, and it works perfectly fine.
Any idea what's going on and how to finally fix this?

It sounds like you have the SMC router from Comcast. While you can try putting it in bridge mode, my advice is to replace it with a pure cable modem, like the SB6183. COmcast can provision that with static addresses if needed, and you don't have to fight the the SMC trying to act as a router.
This se up will be more reliable, and you will avoid issues with double NAT and other problems by Comcast trying to provide "value added" routing when PFsense is far better a router than that POS SMC box. :)
Thx

MikeYou know what's funny? We just did that. Replaced it with a ubee. Finally got 2 charter reps to admit that SMC has a firmware issue with static ips. Network came back up immediately on that ubee modem when we got it provisioned :)
