Router won't connect to internet (Comcast modem) anymore

Current model Arris TG 862 v5
No ability to ON/OFF wireless or change modem mode to bridge, via webgui.

Whenever comcast changes customer ip address, the modem does a reboot, and I am forced to contact comcast tech line to have modem placed in bridge mode, in order to use own wireless router (R7000).
Sounds simple enough, yet twice, i have had telephone tech support deactivate modem. No Internet and No telephone. Forcing me to call from cell to make service appt. As previously stated, service tech at my home two hours, in order to have modem set correctly (a.k.a. My Way).
Sorry for highjacking thread from OP, but prepare for the worse, when dealing with comcast telephone techs.

I intended to write
I want Gateway mode, and not bridge mode

You mean Arris TG862G?

I used to have arris modem with telephone from Comcast up till last year and ip changes does not cause grief at all. I had no wireless version

I have the Arris TM722g modem here, and Comcast changes my WAN address whenever they want to (surprisingly frequently). Has no effect on my networking here, modem and everything just continues to work fine. The only time I've needed to reset the modem is when Comcast makes some kind of configuration change, like when they enabled IPv6, or when they did something with the bonded download channels, and I got a speed increase by resetting.

I'm surprised that the Arris can't be configured by Comcast into bridged mode, so that you can use your R7000 as your router rather than the Arris. Sounds like you might have some uniformed Comcast people that you're talking with. Have you looked at the user's manual for the Arris to see if it can be put into bridge mode?

Yes, that is my current model modem. There is a v5 printed next to model #.
I started with a similar model without wireless, also last year, and when I moved to triple play, comcast changed to wireless modems and the X1 cable boxes. All modems were/are wireless models. I was told customer has no choice in modem, since all issued have wireless capabilities.
Locally, comcast changed ip address once each month (Jan & Feb), hoping they will skip this month. When I experience any problems with comcast, i take a deep breath and think of the South Park episode, where the cable people give themselves titty-twisters as they feign concern for their customers, and then I dial comcast tech line.

On a happy thought - I am using the latest official fw with zero problems with my R7000. The R7000 is a significant step forward, from my now dead wndr3800, which had served me well.

My ISP wanted me to use one of their modems, but after talking with them they agreed that my Zoom modem was all around better. They claimed that they still had to send me theirs and to this day it sits in the closet in an unopened box. That could be one option, buy a better modem and supply them the MAC address. Note that some ISPs will still balk because they want the rental fees.

Another option would be to keep having them replace the modem. When they complain to you about constant calling, tell them that you wouldn't have to keep calling if they fixed the issue or let you use your own modem. Note that you could become a nuisance and they might cancel your service.

My point is, I would not put up with the current situation. There is no reason for your current modem to not seamlessly handle any IP address changes from your ISP. Either the modem or the ISP is the issue. You should not have to deal with ISP IP address changes. That is not your problem.

Clark_Griswald,

They might be forcing the WIFI now to build out their HOT SPOT roll out. Meaning each modem serves two purposes one SSID for you and another hidden type to build out their HOT SPOT. Check to see if you can pickup their HoT Spot.


Also have you used the X1 HDMI connection to your TV. If so any problems? Does it pass DD? Does the video and audio loose sync, the lips move then a second later you hear them.

How does the XFINITY WiFi Home Hotspot work?

Your XFINITY Wireless Gateway broadcasts an additional “xfinitywifi” network signal for use with XFINITY WiFi. This creates an extension of the XFINITY WiFi network right in your home that any XFINITY Internet subscriber can use to sign in and connect. This XFINITY WiFi service is completely separate from your secure WiFi home network.

I found this last year @ my nephew's house, I disabled it. I think it's BS that Comcast doesn't inform customers that this is going on. Bad link BTW
