When we switched to XFinity for our internet access, we changed our printer from being connected to our old Cisco router to being connected to our new XFinity router. When I go into the Comcast Gateway, I can see that it shows the printer as connected. However, when I try to add it using "Add a Printer" it won't show up and when I try to use the IP address or the Hostname to add it I get an error message saying the printer and laptop are on different networks.
If I manage to get it added as a printer, when I send a print job to it the print job errors out.
The only way we've been able to print is that, when we boot up, a generic driver runs and says "your device is now ready for use," the printer appears in the Devices and Printers screen, and it will print simple documents. The problem is this printer is a multi-function printer/fax/scanner and I can no longer access the faxing and scanning functions. HP repair tools can't see the printer at all, so they are no help.
Did multiple uninstalls and reinstalls - made no difference.
I finally got help through the HP Support Forum - turned out that I needed to reset the Network Defaults on the printer to clear the prior IP address from the device memory, then do the reinstall so the printer got a new IP from the XFinity Router, then assign it a Static IP address that fell outside the DHCP Range (which meant first adjusting the DCHP range). Final step was to create a Standard TCP/IP port using the newly assigned Static IP address.
Now it works.
I had this problem about 1-2mos ago and nobody was able to resolve it but it "magically" fixed itself:
I can only access google and facebook sites, e.g., google.com, gmail, facebook, instagram. All other web sites I try don't work. DNS works. And a traceroute on the other sites shows the connectivity stopping somewhere in the xfinity network.
The problem with reporting this to an agent is they all say, "I see your internet access is working...", which is true, but they can't resolve the real issue: my connectivity is broken somewhere deeper inside the xfinity network.
Sorry, yes, I had fixed it.
Btw, ComcastJohnN took me through a few tests and checked everything on the Comcast side and determined my problem is my home network was not generating ipv4 addresses for my devices. It was an anomaly in my router and rebooting wasn't fixing it.
Central Connecticut Hartford County looking to see if/when D3.1 is in play?
The tech just finished the install for my new service (Performance Plus and Extreme Pro), but it looks like I'm only getting 75 mbps (per multiple devices, and multiple speed test services) rather than the 400 mbps for Extreme Pro. I was able to get the bootfile from my (cm1000) modem: d11_m_cm1000_performance2_c01.cm
From what I can tell, that's not the bootfile for 400mbps service?
Additionally, I can't log into the xfinity site.
I get "We couldn't sign you into My Account.
Unfortunately, you won't be able to manage your account at this time."
I successfully reset my password, but that did not change anything.
Yep. That's not the correct boot file. The boot file for the Extreme Pro 400 speed tier should look like this;
*****denotes modem model number.
You can try calling 1-800-comcast and ask a rep to *roll and re-provision* the modem. Also ask them to confirm that the provisioning and account data in their database is correct and complete and that the correct configuration / bootfile for your subscribed to speed tier is being pushed to the modem.
I have Xfinity internet and voice, and I have owned my own Arris TM 722G EMTA since August 2012. I recently upgraded to the 250 Blast Pro! tier (250 MBps). Unfortunately, I did not check if my modem could support this when I made the upgrade, and I have only learned this after the fact. The fastest download speed I can get out of my modem is in the 90s. Upload speed is ok, about 12.
After a chat session with Comcast where they re-provisioned the modem and the speed did not improve, I realized that I needed a new modem. Using the Comcast device website, the only non-Gateway EMTA that shows as "approved" for my area (greater Bay Area) is the Netgear CM500V. I really do NOT want a gateway, I prefer having a separate router. Unfortunately the Netgear CM500V is out of stock everywhere online and in the Bay Area at the moment. Amazon and Frys (among others) have the Arris TM822R in stock. This looks like it will work for my new speed, but why does Comcast not list it as "approved" on their website? I realize that the max speed on the the Arris TM822R is less than the Netgear CM500V (and it has less downstream channels), but it seems like it should work. Again, why is it not Comcast "approved"? I would prefer the Netgear CM500V, but I do not know when it will be available again.
I've read on these forums about having multiple devices (one EMTA for voice only, one modem for data only), but I would prefer to avoid this if possible.
Alternately, I'm thinking that it might be time to ditch Comcast voice and use a VOIP solution so I no longer have to mess with an EMTA. Does anyone recommend Ooma or something similar that works well with Comcast internet for VOIP instead of Comcast Voice service? The ObiHai devices used to get good reviews, but it seems like they brick the devices after 3 years to get you to buy a new one.
Thanks in advance.
The people to ask about the retail availability of the Netgear CM500V would be Netgear. I have read on the dslreports forums that it will be available end of April, but you should probably ask Netgear themselves.
If you already have the Arris 722G, why not try the double modem approach? 722G for voice then you are free to get one of the latest devices D3.1 devices for internet, if the sigs are ok you should be good.
I did drop phone for a Vonage promotion, that is running out soon, so I may well go with my free google voice number and connect that to an Obihai with callcentric for E911. Should be a couple of $ amonth.
You need an Emta with 16 downstream channels for any tier with 250/300 down, so the TM822R 8 downstream wouldn't do it. Overprovision speed around 300 down with 250..
Also if you're only getting 90 down, be sure to check any directly connected devices have a gigabit NIC, not 10/100 fast ethernet.
When I connect Mac directly to SB6183 with Ethernet cable, no internet. When I connect AirPort Extreme to SB6183 and Mac to AirPort Extreme then internet is ok. Thanks in advance for any ideas
powercycle the modem before plugging in the mac or after?
also a network switch right out of the modem is ok?
No, a switch is "dumb" device and it won't know how to route traffic properly. You want a router right off the modem.
was told that I needed to replace my modem ( I owned ) to be able to get to the speeds I am paying for ( Blast 200~250) however, the new modem (Motorola MB8600) is running at same speed ( 90~95) as I was getting with the old modem.. called it in, and support cannot "see" the modem, even though it is working.. it does not appear in my devices on website either.
tech scheduled a site visit, but I am not sure that will do much.. my house has nothing on the inside, just a straight cable run to the modem.
Will I damage my modem if I hide it in a container when guests are occupying the bedroom?
I currently rent the equipment from Comcast and am looking to buy my own. When I was looking at Amazon.com some products said they were modems only and needed a separate router. Do I have to buy 2 things? If not, could someone suggest (with link) a good product to buy, somewhere in the $100-$150 range? Thank you!
A modem is typically used by itself if you don't need Wi-Fi. If you want Wi-FI or have multiple devices, you would then need a router. If you don't want to deal with setting up two devices, you can purchase an all-in-one device known as a gateway. If you prefer a gateway I'd consider the Motorola MG7540 or the Netgear AC1600.
https://mydeviceinfo.xfinity.com/ will show you approved devices for your speed tier if you would like to explore other options.
