Old login e-mail a black hole

Old login e-mail accounts are now a black hole. They recieve mail but it doesn't go anywhere. Fix these so they bounce properly. Comcast put so much effort into screwing up this migration that I'm not paying anything for it. The Comcast Cloud Solutions page is an endless spew of content-free mar

It's finally bouncing due to no MX record. Thanks if you just fixed it.

Blocked at AWS?

I'm no longer able to reach http://angel.co from Comcast Business. Traceroutes from Comcast and T-Mobile look the same because almost nothing along the path supports pinging, but T-Mobile works.

Nevermind. Angel.co sent me a bad HTTP cookie that was causing the AWS load balancer in Comcast's path to drop the request.

Modems keep failing

I've been a customer for 18 months and I've lost track of how many times I've needed the modem replaced. The first few modems rebooted several times a day. A Cisco worked for a while then 1:1 NAT quit forver. My new Netgear CG3000DCR didn't even last a month before it started needing regular powe

Networking with cat6 and Comcast business class with 2 access points?

Hi, hoping you can help. I'm trying to help a friend setup Internet access all over his property including a large house and separate shop. He has business class (with voice) service currently and has ran cat6 to the A. P. Destinations. His gateway is the Dpc 3941B. The 2 A.P.s are a linksys E 2000

Enable routing on the modem/router then set all the WiFi access points to "bridge" or "Access Point" or whatever disables NAT and routing on them. Make sure the access points aren't grabbing a public IP address for their configuration interface.

1-1 NAT died

I have a Comcast Cisco DPC3941B modem that has features randomly stop working. Today it's 1-1 NAT. I have two WAN IP addresses mapped to two LAN IP addresses. The outside world can ping the two LAN devices fine but they can't maintain a TCP/IP stream. Just a few packets trickle through per minut

IPv6 just died

IPv6 just died a few hours ago. It was working fine for months and, no, I didn't touch anything. I don't have a router. It's all devices at once (MacOS 10.6.8, MacOS Server 10.6.8, and Android 6.0.1) All LAN devices can ping the modem. The modem's diagnostics has full IPv6 connectivity to the LA

I don't know what config Comcast pushed out to the modem, but it needed a full factory reset to work again.
