We are using Comcast Business Starter Internet for our office and planning to buy a modem instead of leasing it. I'm checking Comcast's website. It's showing the following modems are compatible for our service. Arris/Motorola Retail SB6120 SURFboard DOCSIS 3.0 Cable ModemArris/Motorola Retail SB6121

We have a Comcast Business IP Gateway (SMC 3DG) and one Comcast-provided fixed IP address. To make our router/network more secure from outside intrusion, I am planning to enable the "Disable Ping on WAN" setting in the router's firewall firmware. Other than occasional employee remote access (via por

Is there a way to clock certain incoming numbers? We keep getting spam calls from a few very specific numbers. I know I've done it at home in the past. I looked at the Manage Call Security and Privacy page and none of those options are what I'm looking for.

We have had no phone service for 2.5 days at this point. We know there's nothing basically wrong with our line as it also supports our internet connection. We are too small to have a phone system - so its just POTS. We are a small business run from our home. This may be rare for you guys, but its ac

I saw last night reading the news, home users of Comcast wifi can enable push notifications of devices joining the network and any changes to the network. Will the business side get this ability?

I have tried several times to connect to an xfinitywifi hotspot and each time to no avail. We have one here on our own gateway and cannot even connect to that one as a test case. I can direct my android device to connect to the xfinitywifi SSID just fine and it does so. Launching the browser never r

We're getting incorrect DNS responses. I have 5 static ips. My systems all use Google (8.8.8.8 and 8.8.4.4) for DNS resolution. However, the gateway router uses Comcast DNS (75.75.75.75, and 75.75.76.76) There seems to be no way to change the DNS used on the router. We also run FIOS. My guess is tha

We have a DPC3941B in pass through mode with static IPv4 and IPv6 addresses. I am having trouble getting IPv6 routing through the modem to our firewall. There are three possible ways that this could work: 1. Put the modem in bridge mode and lose our statics. This will allow our Ubiquiti router to us

I would like to simply upgrade my current business plan to a higher tier without signing a new contract or dealing with a sales agent trying to upsell me to new services I do not need. I have been a faithful customer for years, yet all online paths lead to the same screen, requesting a callback from

We just switched our phone and internet provider from Verizon FIOS to Comcast Business, and Comcast provided us with a Cisco DPC3939 modem/router. We have had an issue connecting our Epson WF 7510 wifi printer to the network. When I go through the printer wifi set up, the printer says its connect to

I need to request an rDNS change. Thank you.

We have 4 emails on the hosted exchange service. 3 systems were setup and functioning properly for months. Two days ago we started receiving the following error message in Oulook: "the folder has not yet been updated" The second problem happens when setting up a new install of Outlook and I assume i

How do I change the number of rings before people go to voicemail on our standard voicemail ?

Using the new voiceedge Windows App and USB Headset. The headset will ring when there is a call, however if I have my headset on the charger, I can not hear when a call comes in. Is there a way to simultaneously ring a different audio device (PC sound card/speakers) and the headset so I can hear whe

Dual-Stack have been enabled on both the SMC D3G CCR and the Cisco DPC3939B.. If you dont have dual-stack reboot your device and the bootfile will enable it..

I've called in about this issue, but evidently they didn't fix the problem. Aside from being bugged by snail mail to add TV I don't want, I keep getting snail mail from your sales department trying to sell me business internet. The problem is I already have business internet, and it's annoying to ge

I lost Internet on New Years Day. It seems to be equipment failure at my end. They scheduled a Tech to come out that day. Later that evening they call and say they are sorry they were understaffed and would have someone out to me on Saturday. Saturday comes and goes and afte 3 long phone conversatio

Can someone please reset the default password for my gateway, the id of cusadmin with a password of highspeed is no longer working.

...Wonder if this is taught or an acquired skill of on the job experience? Yes my internet was down and I think I know why.

I don't know why my secured netgear network is gone. I turned my ipad on at work and all the other businesses secured networks are listed and mine is not. I talked to the phone tech and we did all the reboot steps and still no network. She said the problem was on my side. I am just about to throw th
