Arris TG862g is broadcasting a hidden network

Our family recently got a new modem, the Arris TG862g. Its working great so far, wifi is reaching all ends of our house (though a booster is needed at some ends).

 

Since we have gotten this modem though, a hidden wifi network is being broadcast through our house. Our neighbors are not close enough to us for us to pick up their signal as we are in the middle of a 5 acre plot (and this signal is full strength). Our 3g/mobile devices are not configured to be broadcasting a hotspot either. 

 

So what is this hidden network? Why would this modem even need to be broadcasting a hidden network, I'm not seeing any configuration in the router menus that would indicate why or how. Could it be something comcast hid in the modem for their support guys if they make service calls?

What is the SSID of the Secondary Network that is being broadcast?

Do your Boosters Boost the secondary signal as well?

Re: Arris TG862g hidden network

We dont have any boosters. I was just saying I plan to get some.

 

 

That aside, the SSID isn't being broadcast, it just shows up as a hidden network.

I've tried using the main wifi SSID as the hidden wifi's when asked and tried using the same password, as well as the original long password, but it wouldnt connect.

I am going to try using inSSIDer to get more info, will post it soon.

Re: Arris TG862g hidden network

Whatever it is, its using a different MAC address but its broadcasting using the same config such as Wireless N, WPA2-Personal, same channels, same signal strength. 

 

------------------

 

Edit*

 

I changed the channel out of curiosity and the channel on the hidden network changed as well.

Does it disappear if you unplug the CC gateway device from the A.C. socket ?

Re: Arris TG862g hidden network

Oh so thats what that is. and yes it does. Any changes i make to the main wifi network are subtly reflected in the hidden network (unplugging, channel changes, etc).

 

Thanks for the links, helped out alot im gona see if they can switch that off as no one will benefit from a hotspot in my area in the middle of nowhere lol

Looks like the customer has the ability to disable it.

Re: Arris TG862g hidden network

Thanks again. Im going to get them to opt me out. With this hidden network, the router transmit strength isnt what its supposed to be, its cutting it down by almost 30dBm

Re: Arris TG862g hidden network

Tried to get them to opt it out and they ended up shutting off my entire wireless bridge

Re: Arris TG862g hidden network

Many subscribers can opt out on your own, in the Comcast.net / my account / acct pages, my services.  No need for CSR's to mess things up.

Re: Arris TG862g hidden network

I have a TG852G which is currently broadcasting the hidden network, but in my "My Services", I don't see the icon of the gateway modem and the switch to turn this network off. Is the switch only available to TG862G ?

Re: Arris TG862g hidden network

In my case: Man Mad tried to opt out and went on a chat with tech support to be advised to call their tech support line. Got the first line support person which got confused and turned off completly the WiFi in the gateway. After getting it back the hidden network was still there and got transferred to a Wireless specialist department person which seemed to be at some remote location as the line was really bad. After repeating what I wanted which is to opt out of the XFINITY WiFi Home Hotspot and get rid of the hidden network, the support person asked for a subscription fee of 9.99 a month !!! to "fix" the problem. I then quoted the FAQ at http://www.comcast.com/wifi/neighborhood/faqs.htm?SCRedirect=true

 

Q: How do I disable/enable the XFINITY WiFi Home Hotspot feature?

A: We encourage all subscribers to keep this feature enabled as it allows more people to enjoy the benefits of XFINITY WiFi around the neighborhood. You will always have the ability to disable the XFINITY WiFi feature on your Wireless Gateway by visiting My Account at http://customer.comcast.com or by calling 1-800-XFINITY.

 

At which point they hanged up on me !!

 

Never seen such a rude and ineffective tech support on an issue which is publicly documented.

Good to know that some other folks are lucky to be able to that on their own.

Gia-khanh,

Did you try disabling it from your primary account page?

Re: Arris TG862g hidden network

The my services page is actually really really buggy. Sometimes the "wifi hotspot toggle" is there, sometimes it isnt. or I guess comcast doesnt like the chrome browser that much haha. 

 

BTW mine is still broadcasting the hidden network even after turning off the hotspot. I probably need to do a hard cycle of the modem but....after spending 3-4 hours on phone with support trying to correct the mistake that they caused earlier...im not touching it.

Re: Arris TG862g hidden network

Yes I did use the main account for customer login and I could not see the gateway icon and the toggle switch, so there is nothing for me to act on to disable it. BTW, I've been using Windows 7 Internet Explorer.

Apparently there's no way to get rid of the hidden network.  You can disable the hotspot,  but the network stays.

Re: Arris TG862g is broadcasting a hidden network

The HotSpot on/off button on comcast.net page will not remove the hidden network. Put whole device in Faraday cage no more hidden network or any wifi. Didn't need wifi from comcast just wanted basic gateway.

If you have your own router, and are using it for WiFi, call in and have the Arris put in bridge mode...that will disable the router and wifi function that are built in to it.

Never thought, that in this day and age, I would meet a person that could use the term "Faraday Cage" in a sentence that made sense.  Kudos

Wha did you use to make your Faraday Cage?

Re: Arris TG862g is broadcasting a hidden network

Tin - I mean aluminum foil? j/k Smiley Happy Seriously though, some metal screen material like that on many screen doors would be fine enough to work, while not blocking airflow. Quite frankly, the idea of having wireless users on my Internet connection that I can't block/monitor is very scary, given the over-reactions these days to "Internet crimes" with no proof other than an IP address (which is very spoofable). I hope they at least had the sense to give it a second address or use a forced transparent proxy.

 

It's annoying that that 'feature' is hidden behind some Password of the Day *ominous voice*. I checked and you essentially have to get them to bridge it and let you use your own router. Had same issues with a DPC2100 before it. At least it was just a transparent modem. It's just the way Comcast has their policies. Don't like it - buy your own and stop renting, hehe.

Re: Arris TG862g hidden network

they removed the toggle ability to opt-out on September 23 according to one service rep.  i've been trying to do this for hours and no one will disable to home wifi.  I don't care if it's a separate network that doesn't affect  my capabilities.  I don't believe it, and I'm not paying hundreds of dollars to be a service beacon.

Re: Arris TG862g hidden network

My house is pretty isolated so I'm not worried about not being able to monitor the network. The only thing that bugs me is that it because it is broadcasting on the same channel, and thus frequency, I feel like it is causing interference which could affect my WiFi coverage or strength. Anyone have any input on that?

Re: Arris TG862g hidden network

I was told by one of their "highly qualified technicians" that you cant opt out.   I originally called about getting the "xfinitywifi" hotspot turned off and also noticed the hidden network.   

 

He said that basically any DOCSIS 3.0 compatable Gateway (cable modem & router combo), will get provisioned to throttle down your wifi channel to DOCSIS 2.0 bandwidth, giving the rest to  this hidden channel.

 

Needless to say, I was not happy to find out that XFinity is using my house as a hotspot for their customers.

Re: Arris TG862g hidden network

Besides my wifi network's SSID and the xfinitywifi SSID there was a third wifi network with no SSID that followed when I switched channels. I got a letter about xfinitywifi a few months ago, which was a short time after I'd noticed the xfinitywifi SSID had popped up. Since then, I've had no issues with my wifi. But just this last week, I noticed a huge slowdown. Wired connection to the router tested at 57mbps but over wifi I was lucky to get 15mbps. Switched to a channel that had no other signals and the problem didn't go away. When I was scanning channels and after switching is when I noticed the mystery signal (in addition to my signal and the xfinitywifi signal). A tech disabled the xfinitiywifi SSID and it disappeared but the mystery signal stayed. The mystery signal has almost the same mac address as mine, just the first octet is different. And I can tell it is interfering because I was able to do a speed test when its signal momentarily dropped while that of my SSID stayed strong and it was like night and day (52mpbs instead of 15mpbs). The tech said the signal could not be disabled, the only way around it would be "a standalone modem and sidecar router solution". Well that's not much of a solution to me. How is this fair? I have to have a wired connection to the router in order to get the speeds I'm paying for, and in order to use wifi I have to be willing to sacrifice 2/3 to 3/4 of my download speed? What's the point of 802.11n if I'm getting speeds barely faster than 802.11b? I guess it's no longer the "fastest in-home wifi"... I pointed some of this out to the tech and he offerred to ship me a replacement device. I'm not holding my breath, but we'll see I guess.

Re: Arris TG862g hidden network

I too have the same problem and got nowhere with Comcast. I DO NOT want this hidden network broadcast from my gateway. If I can't find a way to get rid of it I guess I will have to go the bridge route. This is not right. I just hope someone will find a solution.
