XR500 Wifi No Internet
5268 AT&T modem is setup in DMSPlus mode to allow all traffic to XR500. It was working fine for 2 months. Now, I cannot access internet whether hard wired or over wifi. All devices see the wifi and ca...
- I got the Double NAT issue a couple more times. On the Modem’s firewall rather than DMZ, i changed the firewall to allow xbox one game traffic specifically to pass through. It looks like this fixed it without blocking all internet access as DMZ mode had done.
Thanks by the way for all your help.
Yes ISP radios are off. Router and modem are about 18 inches from each other and always have been. PC cannot reach internet via LAN. Though from cmd line, I can ping websites. In case it matters, on the reply from ping, the first packet is always lost. It says General failure. Then I get three replies. ISP had me run tracert from cmd line and according to them it was normal. If i use the AT&T modem w/o the XR500, I can connect normally to Internet via LAN. If i turn the ISP radios on, I can also connect to internet through those (with XR500 off).
the updated firmware came out on 8/16? I did have auto update on. I first had loss of internet on 8/15 but reboot fixed it. Since 8/16 no internet access using the XR500. I suppose it could be coincidence but isnt that a red flag? Can I roll back the firmware? How would I do that?
