I can't believe this has to be done for a "Business" class account, but here I am posting in the formus asking for reverse DNS.     You can check the whois and DNS to verify that it matches account records.   Thank you,  Kevin

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 ser

This is a pre-sales question, but the sales folks do not seem to be able to tell me.  I am looking at getting a block of static IPs, and from what I gather, I will need to use the business gateway for this.  I was told that I could use my own router.  How are the static interfaces coming from the mo

Hey,  I just moved off the SMC modem/router over to a purchased SB 6141.  Now whenever I use websites that detect my location it believes that I am located in South Carolina, not Minnesota.  My speed test results are also sometimes the same as with the SMC and sometimes worse.  Could this location i

Previous admin has left and apparently changed the default password.Thank  you!

Comcast offers a public wifi using their customers' wifi as the hot spot. Ever notice a wifi nearby with great signal that needs no password to connect to? Well that is 'xfinity wifi'This allows people like myself to sign into your wifi for free by logging in with my xfinity email and password at an

My bill is showing a 9.99 charge for equiptment rental, but I am providing my own modem... how do I get this charge removed?  I don't see any method for contacting billing anywhere. Thanks!

our office (Comcast Business) connection is up and reachable from ISPs outside Comcast - but multiple users with Comcast home connections cannot reach the office. (get DNS but cannot connect -or even ping). First failure we're aware of was apparently last Thursday 7/17/14. Anyone?

How many email boxes can you have on a comcast hosted business class domain??

You've had techs out four times. Replaced the modem three times. Replaced the lines one time.  My speed average for today: Up: 5.5Down: .08 Wow - that's blazing speed.  Tried calling tech support. Looks like the days of 24/7 are over - now I have to call in the morning. This is rediculous. I'm payin

Hello All, I've been running into some real issues with my business class internet account.  I signed up for comcast business class on 9/25/11 at my home and used it to run my home based business, unfortunately I shut my business down about a month ago.  I decided to keep the internet until the end

I have just moved from Comcast Residential to comcast Business. The business installation is complete and the service is on. I have an existing home - home office ethernet network with Newest Apple Router which I like verymuch and I would like to continue to use it in future. As a part of business c

I have a weird issue - I'm on a 25/8 plan, and normally get a steady 30/8. But about 25% of the time my performance crashes down to 1 or 2 Mbps if I'm lucky (sometimes 400Kb/sec or so!). After two site visits not really resolving the issue (including a swap out of an SMC modem), I think I've finally

Over the last week my business has been seriously affected by intermittent connectivity problems. On three occasions service techs have come out to our building and found that the signal on our line is too high. On each occasion the tech has changed a splitter on the line to our modem. This helps fo

From the start ,I do want to say the 75 Mbps service delivers the kind of speed I was looking for. So on that score I am a very happy camper. Now it is time for me to be looking into the software components that are part of the plan I signed up for. I wanted to get some information on these products

GMail is really clamping down on IPv6 FQDNs and it's my turn. Please assign a Comcast Support member to me so we can set up reverse lookups from my IPv6 block to my host.

Does Comcast Offer a Wireless backup connection through current router like a wireless card (USB) that could be connected to the router, that would switch on if internet through Co-Ax is down? (Maybe it could connect to internet through a Comcast HOTSPOT or something) - I have a store location that

My issues started just yesterday morning after receiving the email that we were being upgraded to 2010.   I can sign into MyAccount, I can get my email on phones and I can get my webmail. I CANNOT get it through Outlook.  After much forum reading I have upgraded my MX records and the CNAME records a
