I am a Comcast business customer. We do not have Xfinity WiFi on our Comcast modem.
I have a Macintosh laptop. I want to get the Xfinity WiFi Mac OS app and profile, but to do so the FAQ (http://wifi.xfinity.com/faq.php) says:
Setup Secure Connection -
From Settings -> Wi-Fi -> select "XFINITY"
Enter your Comcast username and password to join/connect
Re-enter username and/or password. You may also name your device.
Follow on screen prompts to install profile. Please Note: You will be prompted for your device passcode.
BUT, how do I know I’m connecting to a REAL XFINITY network in the first place and not someone who has just setup a fake network named XFINITY that shows the same login page?
I want to install the profile from a secure wired or wireless connection through my Xfinity internet home/work connection. How do I do this?

OK, after some private discussions with Comcast, here is what works:
1. Connect to your own known secure WiFi network.
2. Download XFINITY WiFi manager from http://wifi.xfinity.com/download_mac.php
3. Install the XFINITY WiFi manager.
4. Log in to the XFINITY WiFi manager using your Comcast credentials while on your own known real and secure WiFi network.
5. You can now go to locations where XFINITY WiFi is available and will be able to access the WiFi network without entering your Comcast credentials.
Additional info is about using the Macintosh WiFi Manager is http://wifi.xfinity.com/connect-devices.php#laptop
In addition, in your Control Panels you will see a Profiles icon that will list the XFINITY WiFi profile.

The service is working great but my gateway will not display the connected devices. Look at the picture. The gateway will tell me that there are 16 devices connected but will not display the details.
There is no firewall, just a switch. DHCP is run thru the comcast gateway. Any ideas what is happening here? Tech support on the phone wasn't able to provide an answer

I am having the same problem, my list of connected devices appears empty. I wrote down the MAC addresses and assigned IPs when the list was visible, and those IPs still respond to connectivity tests with diagnostic tools, but I cannot handle that list any more. Furthermore, when I try to add a device with reserved IP I always get an "Invlid IP address" alert.
This is how it looks for me:

I followed the instructions in the Manage your XFINITY® WiFi hotspot online article to try and disable the hotspot. I did not have the Manage XFINITY WiFi Hotspot option is references though.

If anyone's paying attention to this thread, and feels like disabling my wifi for me, I'd really appreciate it.
I'd even more appreciate the ability to disable this myself.
It is really unbelievable that a business such as Comcast would force it's customers into sharing their resources involuntarily.
I see that as a poor business practice.

I have a DPC3939B router with static IP's. I am running into a problem where (seemingly on it's own) it is disabling the "Disable all rules and allow all inbound traffic through" Check Box/Setting. The log files confirm this and it is not related to any user logins. (See log below - Red Entry). In any case, the tsip_pm_enable setting is getting flipped every few days to every few weeks. When the tsip_pm_enable setting gets shut off, it causes all kinds of performance problems, and obvious security concerns. The logs do not seem to reveal any deeper insight as to the cause. Obviously, I WOULD like to end this behavoir! Any Suggestions?

Hello my-spot and welcome to forums,
I apologize for the delayed response to your post. I am not sure if it is an configuration issue on your modem or perhaps a poor response to a firmware update. I would like to factory reset your gateway to see if this helps. Pending the results of this reset we may need to send out a tech to replace the device. A factory rest can take up to 40 minutes to complete, do you have a preferred time for such a reset? (AM|PM)
Some one changed the login that is no longer with my company.. can you reset it automatically?

Hello autri and welcome to forums,
i apologize for the delayed response. I have reset your modem to the default password "highspeed" without quotes. Please let me know if you need help with anything else.
Your modem password has been reset back to default.

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 we have constant issue at, and was wondering if Comcast offered some kind of redundant solution. Thanks

Hello DaveLibby and welcome to forums,
Unfortunately at this time we do not offer a modem that supports multiple connections. There are 3rd-party network devices that supply such a feature but this would require you getting a second signal (non-coaxial) to create the redundancy at your location. I hope this answers your question.
With your location having the connection issues. Please send me a private message with that account information so I can review it for you.

Here is our setup:
We have static ip addresses and the modem is in the bridged mode.
We have only 3 devices on the network:
1. Computer A with a web server and a dns server running Windows 10 pro.
2. Computer B with a web server, dns secondary server, and an email server running Windows 10 pro.
3. A netgear wireless router providing wireless to customers
Last week we moved from DSL to Comcast cable. Since the cable was installed we have an issue where the modem will reboot randomly.
Sometimes two or three times an hour, other times it may go several hours before rebooting.
We never had this issue with the DSL and the computers we had with DSL have not changed.
Comcast has changed the modem (Cisco DPC3941B) and tested the line thoroughly. Our upstream and downstream levels are perfect and they have not fluxuated for the entire time.
Our building has several other comcast customers and they have monitored them and us at the same time and none of them go down when ours reboots.
After ruling out the cable and modem as an issue, the next thing we did is look at our machines.
We removed the netgear wireless router but the reboot still occured.
Next, leaving the wireless router off, we removed Computer A, and soon the reboot again occured.
Next, leaving both the wireless router and Comptuer A off the network, we removed Computer B and waited. After 2 hours there was no reboot.
Based on this we conclued that Computer B is having an issue with the modem.
On Machine B is we shut down the Web server, DNS server, and Mail server the reboots seem to stop (we give 5 hours for a test as this is the longest we have gone without reboot since the beginning)
We then try turning on the mail server, and soon a reboot.
We disable the mail server and turn on the DNS server and soon a reboot.
We disable the DNS server and turn on the email server and soon a reboot.
No matter which server runs (alone) the reboots begin again.
We have scanned the machine for virus, malware and rootkit (as we do very often) and it is clean.
We have disconnected the ethernet and connected via wireless to the modem with the same result, so a faulty nic card has been ruled out.
Comcast has sent techs out 6 times in the 8 days we have had their service and they cannot find the problem.
One tech suggested "maybe it is an attack", so we set the network monitor on and waited for an attack and the network usage was unchanged immediately before a reboot.
Also it seems unlikely that an attack would reboot the modem, the modem logs only show the modem getting its address after it powers up again.
No other info is in the modem logs.
Can anyone suggest ideas on how to isolate this problem? Again the same equipment functioned over DSL without any issues for years.
Although comcast seems to be doing all they can (tech sat in my office for several hours Saturday morning as we monitored and tried different things unsecussfully), we obviously cannot functions with random 5 minute drops throughout the day. We process our credit cards through Computer B and when it goes down we are out of business until it comes back up.

We are encountering the same issue (random reboots) with a very similar setup.
Comcast has replaced the modem three times, has moved the outside cable, etc.
We have replaced our network equipment (switch, SonicWall, etc.) but the problem persists.
We're an IT company who provides network services & support to our customers, so we know what we're doing network-wise. (not bragging, just stating that we do this for a living)
When the modem reboots, no other equipment is affected.
Up until yesterday's massive Business Phone outage, our phones weren't affected by the Internet gateway reboots.
Since we use a VOIP system & VPN to connect to our other offices, this brings everything to standstill until the modem boots again.
One Comcast technician said he diagnosed something similar and that the "Maintenance Dept" had finally tracked the problem to the increase in X1 boxes because they send out a signal on the same frequency used to trigger modem reboots. However, no one else at Comcast appears to believe this.
This has been going on for a few months but everything was rock-solid before that.

We finally resolved this, however the solution may not be doable for everyone.
After over 160 reboots in 14 days, I asked the tech if he could get me another modem but NOT a Cisco DPC3941B. He went to their warehouse and got me a old no long used SMC modem, and since he did that, we have not had a single reboot in over 26 hours.
As a test, he left the Cisco DPC3941B installed and ran them in parallel over night and the Cisco DPC3941B rebooted while the SMC did not.
So our problem was resolved by getting rid of the cisco modem completely.
I am not sure if everyone will be albe to get the tech to dig up an old SMC modem, but if you can, it just might eliminate the reboots.
Hope this helps someone, even though we were ultimately unable to determine what was/is causing the cisco modem to reboot.
