I've had Xfinity for several years with very little issues. I just recently upgraded my DirecTV receiver with the 4K version (DVR) and now getting constant drops and discconcts with my Xfinity wifi signals.
The DirecTV is broadcasting a SSID of DIRECTV_WVB_9809xxxx to connect to other DirecTV receivers (of which I have none). I contatected DirecTV and asked them to send someone out (a day after it was installed) because I was getting dropped from my home wifi (Comcast). The tech that came out said he's never seen anything like this and called it in to talk to an engineer, who confirmed, they've never heard of this happening. They concluded it must be the Xfinity home modem that needs to be looked at.
I've tried changing the channel on and using both the 2.4GHz and 5GHz signals, hiding the SSID on the Xfinity modem and restarting the modem. Nothing has worked except for completly powering off the DirecTV system.
There are a lot of wifi signals around my house (from neighbors) but didn't start having this issue until the new DirecTV receiver was plugged in and turned on.
Am I missing something? DirecTV said that they could replace my receiver (again) but should contact Comcast first.
I want to add a computer and printer that are not wireless enabled to my home network. Can I just run a Cat cable to their space from my Xfinity modem and then add a cisco router and hardwire connect the computer and printer that way? Is there any special issues/settings that have to be dealt with? Will other computers in the network be able to see and use the printer? Thanks for your help.
You got it! That's exactly correct. If you have a Comcast all-in-one device (modem/router/Wi-Fi) combo then you don't want to add another router to the network, but rather use a switch. There aren't any software settings you need to change. And yes, the printer should be available to computers on your network if it's designed to do so.
I don't stream data, at least that I know of. I have internet and TV with Comcast, and a home wifi network. I use ATT for my cell phones.
I've never paid attention to data from Comcast, but while browsing my account online, I saw this:
So, where is this data coming from? Could it be when my kids come over, and they don't know that their phones may be connected to xfinity? As far as I know, when they come over, their phones auto connect to our home SSID, and any thing that they do wirelessly over their phones goes through our home wifi network, and out cell phone service is with ATT. And if that's not it, where does this data come from?
Yes, if you connect to Wi-Fi with a phone you would be using Comcast and not ATT. That's why everyone wants Wi-Fi -- it's less expensive to use than cellular data.

I read that Xfinity is increasing download speeds to all internet plans in the NE market area.
Is this true? If so, when/how do I know to reboot the router ?
~ Thanks in advance
Yes, it's true.
All you need to do is powercycle your equipment. The troubleshooting guide will give you exact instruction on how to do that.
I recently upgraded from Blast! to Extreme Pro (400Mbps) but after chatting with support discovered that I could get 986Mbps at my service address. The CSR said that a tech visit was required but I'd rather not get someone to come out if I can avoid it. I own my own equipment (CM1000) and had all the wiring redone from the street to my modem by Comcast a couple years ago after upgrading my set top box. My modem signals show no errors and I get a solid 477Mpbs. Is there really a need for a service visit or can a CSR just remotely update the bootfile on my modem and reprovision?
The downstream power levels are weak / out of spec. This should be addressed first.
Stuff that you can try if it applies;
In a self troubleshooting effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage types like GE, RadioShack, RCA, Philips, Leviton, Magnavox, and Rocketfish from big box stores like Home Depot, Lowes, Target, Wal-Mart etc. Splitters should be swapped with known to be good / new ones to test
If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed, and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.
Hi All (Hopefully Xfinity Tech Support),
I'm trying to get an Openvpn Remote Access Server working for my personal use. What i'm finding is that UDP packets are not reaching my external interface of my firewall. Can this be unblocked?
Xfinity Service (Coax) -> Motorola Cable Modem -> Firewall -> Switch -> Computer
Modem: Motorola Docsis 3.0 Modem (SB6141)
Firewall: Ubiquiti ERLite3 Firewall
Switch: Cisco 3560G
Computer: Vmware ESXi (Linux Ubuntu 16.04)
My packet captures are taken from the outside interface (Facing the cable modem), and i'm not seeing any UDP 1194 packets turning up in my captures. Can anyone help? I've reviewed the blocked port list, but I don't see UDP/1194 on that list. Not sure what's up beyond a Comcast blockage.
Other troubleshooting steps:
- Yes, i did packet captures on my Linux VM, nothing was seem, that's why i went upstream to my firewall outside interface.
- No i'm certain this not a problem with other protocols (i.e. TCP/1194, TCP/443, TCP/760, TCP/32400) i use all of these ports for other services, so i'm not unfamiliar with the setup of port-forwarding, NAT, firewall rules, etc.
Nevermind, totally my fault. I had some silly server configuration setup wrong. I can happily report that I have NO BLOCKAGE of UDP/1194 or TCP/443 my Openvpn (Behind my firewall) is humming along fine and I have Remote Access VPN working properly.
Yay! Thanks for looking though.
Should I switch Arris TM822g modem to Xfinity Wireless Gateway? I already have a new Linksys wireless router.
OP. Just as a FWIW, I always advise posters to stay far far away from those combo gateway devices !! Just look around the forums and you'll see that there are boatloads of issues with them.
There is always an inherent disadvantage with these. Combo gateway devices are always a compromise in both quality and performance compared to separate units. Also, only the ISP can update the firmware so you are always a prisoner of that / them. And the firmware is typically crippled by the ISP's customizing of it and they typically eliminate valuable features.
One of the biggest issues with them is that it is far more difficult to diagnose connectivity issues when it comes to troubleshooting. You can't narrow things down by using the process of elimination by removing just the router from the path. And if either segment fails / malfunctions, you have a total failure. I think that CC made a big mistake when they changed their policy and decided to start supplying them instead of dedicated devices. The suits seem to think that this will save them money for support costs but I think that they are getting far more support calls/complaints than ever... We certainly are seeing far more complaints in forums now !
Another issue is that Comcast has created a publicly accessible 'xfinitiwifi' link on their gateways. It supposedly uses separate bandwidth from your own. You can disable it from a link on the Comcast site, but people have been posting that it keeps turning itself back on every day.
Get separate units and keep the control of your home network in your hands instead of theirs, you'll be much happier !
Does anyone know when the latest speed increase will migrate to Baltimore County? I keep rebooting my modem to see if my Performance Pro has been updated. No increase so far.
Just wanted to thank you again for all your effort. The problem is definitely on my end. The Realtek network card in my HP laptop is limited to 100Mbs download and my wireless card is limited to 130Mbs. If I can't upgrade them, then it will be time to shop for a new laptop. When I got the laptop, even reaching those speeds was unimagineable. Thank goodness for progress.
Have Epson Workforce 840 printer on home network.
Has worked flawlessly for years.
For over a month now, the printer is not being assigned an IP address.
I have the Xfinity ARRIS TG1682 gateway provided by Comcast.
I try all the usual things: reinstall printer driver; remove printer; add printer; power cycle printer; restart PC.
Have tried changing to Static IP (10.0.0.86 was listed at times printer was woking). That did not help.
Sometimes one or more of these procedures gets me running, but I can never repeat it.
What could have changed since it worked all the time?
