Xfinity change router mac address for model dpc3941t

If your renting the modem then just go to the store and replace and if it still doesnвЂ™t work with the new one then it isnвЂ™t the modem/router Why on earth would xFi block my ability to reserve static IPs on my LAN? I can still do it manually by logging into the 10.0.0.1 admin panel. XFi complete blocks any of that because of the security protections it provides from a server level. Highly doubtful I've used this exact hardware to achieve my goal in the past, before Comcast switched over to xFi. The best way to test this is with another Ethernet device and if that device works on the Ethernet, then it is your NIC card on the original device thatвЂ™s bad. The problem is that even though my internet is working, both xFi and my modem list my device as 'offline' or 'disconnected'

My internet works flawlessly, both of the activity LED lights are functioning properly. If your not seeing the link light activity next to the physical connections. It could be the Ethernet port on your device or the router. I've since upgraded to an XB6 model (they had no XB7 models at the office I went to), and the issue has been resolved. This issue arose when Comcast pushed the XFi nonsense.Д®DIT FOR POSTERITY: This was occurring on an XB3 model modem+router combo. They said that a 'private account cannot use static IP', even though I've been able to do this in the past with the exact same hardware and internet plan. Customer service wasn't much help, either.

I'm just trying to set this desktop up with a reserved IP so I can port forward, man. I've already done a factory reset and removed any and all reserved IPs that I could (you still can't remove reserved IPs on disconnected devices for whatever reason) The connection type is listed as Ethernet, but the connection point is listed as Wireless Gateway as well, even though I've completely disabled WiFi on my Desktop.Д®DIT: I've already completely disabled IPv6 on this desktop as well. Two different IP addresses (10.0.0.55 and 10.0.0.80) for the exact same MAC address. Meanwhile, on 10.0.0.1, THIS is what is shown. When viewing device details, this is what is shown. Sometimes, however, it will show up, but only briefly. Logging in to doesn't even show the device at all, under 'Connected' or 'Not Connected'.

Logging in to 10.0.0.1 shows said desktop as 'Offline', even though it's quite obviously online, considering I'm using it to type up this very post Title pretty much says it all, but the details:Д¬onnected via Ethernet (CAT5e) directly from Modem+Router (Model DPC3941T) combo to desktop
