That 5268AC doesn't have upnp and I am unable to effectively forward the ports for my outdoor security cameras. So, according to the ole google and att forums, the trick to bridging the 5268AC and allow a differnent router to manage the network is to take the MAC address of that router, and DMZ that mac address. I did that, and all is right with the world, cameras work, upnp works, hooray. But...for some reason it causes this rubber banding that does not exist when I use the 5268AC by itself. I have no idea if there is a better way to bridge the 5268AC, or a better way to forward the ports so that I can allow the 5268AC to manage the network. It's a real head scratcher. At this point, I'm wondering if I should just put all the cameras on a single router, DMZ that router and let the 5268AC manage the rest of the network. No upnp, so I would have to forward the ports for PS4, XBOX live, etc. Anyone in KC manage networks? I called AT&T and they referred me to Connect Tech. BTW, Connect Tech is a company that fixes issues like this for a fee (it's owned by AT&T). Yep.
Just driving by, but here are some notes, just in case any of it's helpful.
Rubber banding in games is either caused by packet loss or excessive latency.
Packet loss can be caused by either running out of bandwidth or an unreliable connection.
If you are using anything aside from wired Ethernet with good cable, that's the first place I'd look. For example, Wifi, Ethernet over coax (MOCA), and Ethernet over power line adapters are particularly prone to packet loss and latency problems.
You're doing the right thing by trying to isolate the cause.
It's good news that connecting directly to your router fixes it, so it's something within your control.
Anything on the network can be the cause, like a bad device, cable, or port.
At my house, I use a managed switch, which is sometime handy, since it will give stats on packet errors and allow me to reduce bandwidth on certain ports. The wiring in my house was causing problems on a couple ports, unless I dropped them to 100mbps. Unfortunately, it's cat5, not cat5e, but it seems to work reliably at 1gbps on the rest of the ports. Managed switches are usually overkill for home use, but it's nice for stuff like that.
Speaking of 100mbps, if your switch is only 100mbps, that can choke the bandwidth to the whole house. If that's the case, consider upgrading to a 1gbps router and/or switch.
If you're still having trouble, you could try WireShark (free packet sniffer software) to try and look for anything suspicous.
