Google GMail is refusing my email, evidently because while my domain resolves to the correct static IP address, Comcast DNS servers are still resolving the PTR requests to the default standard comcast DNS name. Who do I contact about getting that record removed from Comcast's DNS servers? Yes, I alr

I was changing the DPC's private lan IP to 192.168.100.1 so it wouldn't be in the 10 range (as I use the 10 range behind me router and still want to be able to access the DPC's UI and avoid possible overlap of address space. well now the DPC UI is unreachable. I did a "show IP arp gi 0/0" on my rout

Recently had business class internet installed and I'd like to use my existing ASUS router instead of the DPC3939B. I do not have a static IP and didn't see anything in the DPC3939B's configuration menu that eluded to any "bridge" or "pass through" modes. If someone can assist me in making this happ

I have a CG3000DCR gateway and a /29 block of IP addresses. I have several pieces of equipment that require static IPs including two routers. Assigning my routers two different IPs in my block and assigning the correct gateway, I am able to ping and connect to the router from the outside WAN. I can

I just had comcast business internet installed this morning, and already it has slowed down. I should have 50mbps down and 10 up but speedtest.net maxes out around 23mbps on every host I try. Comcast's own speedtest tool (http://business.comcast.com/tools/internet-speed-test) showed the same thing.

I've been able to set up my iPhone so it receives my comcast email without any problems, but it can't send any emails. Any help would be appreciated.

Jacob, I need to have A PRT record added. Who do I contact to make this happen? Thank you

I cannot get the Comcast employee I am dealing with to honor my request for a manager escalation, so I am turning to a user community. I called last week to coordinate a simple move up one floor in my building, and was told all I had to do was sign the work order and a tech would come out this week

Many of our customers are reporting this message: "Be careful! This sender failed our fraud detection checks." associated with e-mails they receive from us. This seems to indicate an issue with the SPF. When I query our domain, there appears to be an appropriate SPF. We use Comcast for e-mail servic

Hello, I am in the process of changing our primary domain name. I need our PTR recorded updated for IP address: which is currently set to mail.cplawgroup.com to pattimalvonelg.com Thank you, James

As a "Business Class" customer I would never think that I could be sititng on hold for 46 minutes now (and counting) without even talking to a live person. This is amazingly bad. I have 4 other ISP's at our other locations and they will answer within 5 minuntes.. Amanzing ..and now they hang up on m

I recently just had a new modem installed and now when I log in to my account there is no E-mail messages displayed in the upper right and when I try to go to My Services I get "Sorry, you don't have the permission or services to access this page".

We're undergoing a major renovation which requires our service loop roadways to be cleared 3-4ft in from the surface. We discovered the main service loop for Comcast is only 2' down and now need to abate that line and have it replaced. This probably will require a directional bore and I'm looking to

Can any of the moderators here create a separate sub-forum for folks in the IPv6 trial? Seems silly to have all our discussions in the "Connectivity" sub-forum. 🙂

San Francisco business user, internet works however phone is is dead keep answering the calls through my cell phone! Anyone with same problems?

Hi all -- I have Comcast Business 27/7 service (with a static IP, if that matters...), in the southbay, CA. At some times of day, certain sites are quite slow -- while at the same time other sites are pretty fast. It seems that some of Comcast's peering arrangements are overloaded and unable to hand

We have had no internet or phone service for our business in 08540 since 8AM today. Until 2:30 PM, the status showed problems but since then it's all greens but we still have NO SERVICE. No Phone, No Internet and customer service is saying there is no problem even though they can't ping the router e

Is Comcast's communication lines down?.?. It is beyond reason that when a business is in need that a critical from a service provider, Comcast, they are unable to provide a timely solution. In addition, I would have to check my pulse if I were to get a response. If anyone with Comcast is so inclined

I returned the modem on 08/22/2015 because I purchased my own modem. I've been charged the equipment fee on every bill since. Please fix this.
