How To Find Network Key On Xfinity Router
Orencio Suhag
I switched my personal modem/router combo out for an Xfinity gateway and now I can not get my Epson Workforce 845 printer to connect to network. It was working perfectly yesterday with my old modem (which was not an xFinity rental).
I just moved my printer to a different location, it was connected for years, all of sudden it couldn't see my network anymore, I believe I had to change the channel on the router for the printer to connect,
Same thing is happening to me. From searching the forums the problem seems to be related to the new XB7 modems only. I was told I needed an upgrade so I did this but I'm starting to think I should take it back for the old XB6 model and see if they have any left because I had no issues with that and nothing else changed with the network.
Now, looking at the supported wifi modes on xb7.....well....I can't seem to find that, or even a decent manual. I don't have an xb7, but if you use the app, can you select the supported wifi modes? The 'app' is also poorly documented. Perhaps there is an 'admin console' on the gateway too where you could set a wfi mode , but it's unclear if that still exists -- they seem to be moving towards a cloud management/app solution.
Your Xfinity Wireless Gateway comes with a default WiFi network name and password. Most Xfinity Gateways require that the default WiFi name and password are changed during installation. If your default WiFi name and password were not changed during your install or if you have restored factory settings on your gateway, you can find the default WiFi information on the side or bottom of your gateway:
I will give your suggestion a try. (We may even have an old router from before we got our previous gateway, since I tend to put things like that in a bin or box in the basement for later disposal and then forget about them. I'll rummage around this weekend.) One probably dumb question since I've never set up a network within a network: won't the fact that the old router and the gateway will both be sending out signals cause them to interfere with one another?
I've actually got a few WiFi networks for isolation (trusted/non-trusted subnets with a firewall), and it's not an issue for me. If you want everything to be able to talk to each other, take your old dusty router and get the manual for it. See if you can turn off it's internal DHCP server, and then "Forward DHCP requests" to your gateway (10.0.0.1). It might be called "AP Mode" on some of them. Old Buffalo routers even had an external switch for it.
That way, your gateway runs the DHCP server and handles the networking for the internal network. Everyone ends up on the same subnet and can speak to each other if you want that -- although I do segregate things like streaming devices....and anything that initiates contact with a remote server by itself. For your printer, you'll want things to be able to see it from the Xfinity network, so forward DHCP requests. Remember, you'll need to set a unique SSID broadcast ID for it so you know what you are connecting to.
Her work PC which is a Dell Latitude E7440 can no longer see her home network. The Dell Latitude E7440 can see all networks around her home, she can go into the workplace and see all networks, she can connect to other networks anywhere.
Xfinity customer service believes this is a Dell problem regardless of this device working on any other network and seeing every other network available except the home network which became unavailable after Xfinity Technician replaced/upgraded the modem/router.
It sounds like a saved corrupted WiFi profile on the PC. Change the name of the wireless network and see if the PC can see it then. Or plug in with Ethernet. I would reverse any of the settings that limit particular devices on the network, that could come
back to bite you.
You can find troubleshooting tips below when you encounter problems connecting a device to WiFi. Using the Xfinity Assistant or the Xfinity app can provide the same troubleshooting a customer service agent can, but without the wait on the phone.

We just upgraded to the gigabit speed internet, which required us to trade in our old xfinity modem for a new one. Since we changed modems, everything in the house finds and connects to the wifi, except for my laptop, which can't see our network at all. It sees all my neighbors networks but ours just doesn't show up on the list. I can use my phone as a hotspot and connect my laptop to the internet that way just fine, so there's nothing wrong with the wireless card and since I could connect to the old modem it's obviously something to do with the new one. I've tried deleting the remembered wifi network and manually re-entering it, I've restarted the modem and my laptop umpteen times, but still nothing. Customer service has no clue. Can anyone help me?!
Total newbie here, so please forgive dumb questions and lack of even basic knowledge. I purchased a Nighthawk AC1900 WiFi Cable Modem Route for Xfinity Internet and Voice, Model C7100V last year because I wanted to save money and quit paying Xfinity rental fees. When I got the modem I called Xfinity and they helped me set it up. Everything worked fine. Now I have purchased a Firetvstick. When I try to set the Firetvstick up it recognizes my network but the network it recognizes is not what is on the label on the bottom of the modem. It wants a password for the network and I do not know that. The label on the bottom of the modem shows a network name and password that do not work. Even the default access information on the label does not work. How can I find out what the password is for my network? I've seen that other solutions posted here recommend resetting, but I am completely ignorant of what that might do and am afraid of losing my Xfinity access. Can anyone be so kind as to walk me through a solution for this? Thank you very much!
@jlg_07 Did you activate your new combination Comcast modem/router gateway? Then you have to power cycle everything. turn off or unplug modem/router-personal router- computer. Then first turn on the Comcast modem/router gateway, then personal router(if you use one) then your computer.
@ComcastAnna I am having the exact same problem. I have tried everything, including reinstalling the network adapter drivers. I've spent multiple hours on the phone and chatting with tech support. Other than reseting my modem endlessly and without effect, nothing has been done. Options?
Band steering for tri-band radios is relatively new. You can do it a few different ways. Licensed stacks like Qualcom 802.11v work better, but you can also do it with RSSI broadcast strength. The implementation and algorithm becomes important than, and if anyone in a QA department bothered to test it, which sadly, doesn't happen often.
What is Xfinity gear? It's 3rd party outsourced cost reduced product they bought from a vendor. Functionally, it's the Yugo of networking gear, controlled with an app, instead of locally, with quite a few issues, and you can see all of them here.
So in the end, you have to figure out what you got for devices, and which WiFi standard they use. Then pick your hardware selection that will work. That might be a straight cable modem, and your own WiFi equipment. You might want to cover security with something at the same time too because all consumer gear is a bit sketchy in that department, especially if you are using things that communicate with random cloud servers, and especially anything controlled with a phone app (the least secure device you own). You really want to isolate those devices.
Old gear? Sure. 802.11 b/g/n is still around. Access points and WiFi routers. Cheap too. You can run whatever you need for radios as far as performance goes if you want bandwidth higher than that and something that can do it.
Might work, might not. Specific products that do band steering may also have poor implementations that do not work well. Millage will vary. If you can't control the radio, than it just is what it is.
The newest internal adapter (realtek RTL8188CE Wireless LAN 802.11n PCI-NIC) will not display my home network in the list of available networks nor connect to it manually. The other two adapters will display and connect to this network with no problem. The home WiFi is an Xfinity Gateway and is the latest modem/router from Xfinity (Arris TGA4482A).
The one internal adapter that will not display my home WiFi network will connect to any other places I've tried using it. I cannot see the network at a friend's home network that also uses the Xfinity (Arris TGA4482A) modem/router.
I have changed out the realtek RTL8188CE Wireless LAN 802.11n PCI-NIC adapter with another (newer) one that supports b/g/n radio types; it does the same thing. I have updated the drivers on the RTL8188CE and run the Windows network troubleshooting app and also have tried numerous adapter settings changes.
This is a bug that Comcast knows about and intentionally caused a few years back. The update has been rolling out for a while now, but I've heard of this issue from as far back as 2019. I've actually had this problem too!
I recommend you buy your own router and modem, as you'll get full control over your devices instead of relying on the ISP to set up your wifi correctly... They aren't good at it.I have Comcast as well, and use an old Arris SB8200 modem with a Netgear R9000 modem that has the latest DDWRT custom firmware on it. Looking at the amazon pages seems expensive until you remember that you're paying up to $20 a month EXTRA to rent their nonfunctional box.
