Solved: problems with IP Cams (Foscam, etc) after switching from cable co-ax internet to fiber internet

I helped a relative switch from Cox regular internet to Cox gigablast (fiber). Everything works great, except the IP Cameras don't work reliably outside of the home network.

Prior to the switch, on the old cable internet, the Foscam cameras (FI8910W / C1s, etc) would come up reliably and consistently outside the home network, on Verizon / ATT / Sprint LTE phones.

After the switch, the Foscam cameras may come up sporadically outside the wifi network, but come up consistently and rapidly on the home network.

Cellular signal is perfect (4-5 full LTE bars), nothing else has changed.

The switch to gigablast changed the pipe and they moved to a new AC router, but I helped them configure the DDNS / port forwarding exactly like before, along with fixed internal IP addresses for the cameras.

Can anyone think of what may cause this strange behavior? Cox swears they're not limiting or throttling the gigabast internet in any way.

So the IP cameras should be coming up lightning fast on Verizon / ATT / Sprint LTE networks, instead of acting like dial-up or sometimes not coming up at all.

QoS is turned off, just to make sure router is not de-prioritizing traffic... I'm stumped... Confused

EDIT: Solved - netgear router was the problem.

Yup, your description makes me think of DNS troubles, other than that I can't think of anything that might give you these symptoms. If sometimes it seems like dial-up the DNS settings would work and that isn't very likely to be the trouble.

You probably don't want to hear this but maybe you need to give the new router a second look. IP-CAMS should be using UDP instead of TCP-IP protocols. You might check that setting in the router.

Thanks!!

Interesting, I've always used TCP because that's the instructions online... I'll try UDP and see if that makes a difference, thanks!!

EDIT: I changed the setting to just UDP only and it seems to help a couple of cameras, then I changed the setting to TCP/UDP for all cameras and it seems to help 90% of the cameras. 1 or 2 cameras still struggle to come up... odd.

EDIT 2: it has a strange behavior, it will come up once, and then it won't come up again after I close the IP Cam viewer app and re-open it...so problem not solved.

cheap, fast, good - pick any two.

after a ton of testing... trying a different IP Cam viewer app, a different DDNS service, it seems the problem is on Cox's side. As soon as I add multiple cameras to the apps, the cameras no longer show up on the the apps.

Some type of traffic management setting on the Cox server side is restricting the web cam usage.... but if I call Cox they swear they haven't done anything on their side.... getting this fixed is going to be difficult...

Here's a list of ports being blocked on Cox... I'm not using any of these ports: http://www.cox.com/residential/su...0000000%7D

Ok after much testing / exasperation, it appears to be the new router. I put the old router in and voila everything works (but much slower because it's not gigabit), so I've isolated it down to the crappy Netgear router!!!

Now need to figure out what to do...

EDIT: replaced netgear router with new router and voila, all is well. Avoid shitty Netgear routers and their crappy firmware!!! Mad

Did the old Netgear router have internal antenna?

Yes, Netgear R6300v2.

The cams were connecting fine with the Netgear router as all came up instantly inside the wifi network, so signal quality was not an issue.
