I need my wireless gateway/router bridged to just be a modem/phone port... I don't need the wireless, or router.... I think it is absolutely rediculous that I can't adjust this myself, and the person on the phone was too DUMB to figure it out.... Can anybody hel point me in the right direction? Thanks!
No you can't disable WIFI or DHCP to put this Gateway into Bridged mode. Comcast is going to start moving away from this. get used to it. However, you can call Comcast and hopefully you can find someone that can put it in Bridged mode for you.
When they put mine in Bridged mode, it won't recognize the router and I don't have internet access....
right now the best way to use your owned router is have the comcast gateway removed and add a D3 EMTA in its place, especially if you are using an apple airport. they do not work right with the gateway.
it can be put in bridgemode but it doesnt seem to help. there is something going on inside you will put it in bridgemode then if by chance it does work some how it disables it again later. still alot going on with firmware on these devices, i would say right now the fastest way to avoid headache is either use the gateway or change it to just a d3 modem.
I lost bridge mode on my Arris TG862 modem box after a power outage. Made numerous frustrating calls to Comcast tech support and messages to Comcast techs on this forum which were no help or unresponsive. Normal Comcast support said they couldn't put my box in bridge mode and kept transferring me to Signature Service which would address my problem for a fee.
I finally reached out to Chat support on the Comcast.com site and the tech put my modem back into bridge with no problems or questions.
i am having similar issues. i used to have an old emta modem and was able to use my own wireless router without issues. i was also able to connect to my work vpn without issues. i now have the tc8305c modem/router and was not able to connect to my work vpn. i called comcast and they bridged the router, so it is now only functioning as a modem. if i connect my computer directly to the modem, i have internet and can access my work vpn. HOWEVER, i cannot get my own router to work with the tc8305c, so i no longer have wireless in my house for all my other devices. i am extremely frustrated at this point and do not know what to do. when i contact comcast, they show that the internet service is working and will not troubleshoot the router/modem connection. do you know how they were able to get your netgear router to talk to the bridged modem??
I might try connecting the TC8305 via cable to a laptop later today and see if I can go in and disable the wireless before I attempt to connect it to Comcast and my system. Might make it easier to setup my Airport Extreme, which I've read doesn't work and play well with the TC-8305. I'll let you know how I make out.
Be sure that the DHCP server is also disabled (if you can even do this) before using your Airport with the device otherwise you will have an undesirable *double NAT* condition on your home network by daisy chaining two routing devices. You can Google "double NAT" for more info about why it is unwanted.
Well, no joy with the connection via the laptop and ethernet cable. Got into the setup no problem. But disabling the wireless is somewhat less than an obvious choice. Research turned up the manual for the TC8305C. Find it here.....
I need time to read it and see if it has an answer.
The double NAT issue was what I started with when I dropped my old modem from the loop and tried to insert the new TC8305. I've found the setting for the DHCP server, but can't figure how to disable it. I'll need to poke around some.
I was aware of that link to the manual, thanks. I have not seen anything in there about the end user being able to toggle bridge mode / DHCP server but I may be missing something. I do not have this device so I can't check this myself. Perhaps there may be something under the *Advanced* tab in the Admin Tool (page 25) ? I still doubt that an end user can do this. Please let us know if you find something.
I'm beginning to suspect that you are correct. It seems I may have been given bad advice by Comcast support, not that I'm surprised.
I will contact them by phone again tomorrow and try and resolve this with them there. If I get any information that is useful I will post back. But for now, assume that this is incorrect and you cannot change this as the user.
If you would like to use your existing router instead of the routing functionality on your Wireless Gateway, the Bridge Mode on the Wireless Gateway will need to be enabled. A Comcast technician can do this during installation, or call 1.800.XFINITY to enable this functionality.
Combo Devices = Economy & simplicity for provider.... PITA for user.
I will have to call tomorrow, and see if they can setup to make the change after we disconnect our call, wait 5 minutes while I disconnect the coax from the current modem and connect it to the TC8305C. I would prefer to connect only the cable to the gateway while they do this so as not to bork my existing network setup. I am making a large assumption that once they disable the wifi function, I can connect the AirPort Extreme via ethernet cable and it should just work, or at most need to be switched to Bridge mode.
The chat support person wanted to send that command today, even though I explained that I was not connected using that device because I had no internet or phone when it was connected because of the dual NIC issue.
I just went through this process with Signature Service, so I had to pay the $79.95 fee. Technicolor Gateway has to be put into bridge mode on the Comcast side. It took a few restarts, but it worked. VPN (IPsec) is now functioning properly. This is not a customer option through the admin page, unfortunately. The tech fellow did said that it's a simple process. Were a person to call and ask for "bridge mode" it wouldn't cost anything. One or two clicks. I was redirected to Signature Service because I mentioned VPN for work and opening ports. If you avoid those business-sounding code words and just ask for bridge mode, you may be able to switch for free and keep using your own router. Good luck.
Well that's one way to do it, yes mention anything to do with networking and the rep's will try to sell sig service. However, bridging the gateway is free, there used to be a number (now out of use). I believe it was the national activation team or whatever only took 5 mins. It's pot luck with the phone reps, some know how to bridge the gateway, some don't.
If Comcast do care about customer service they should provide a dedicated number for bridging, or as EG hinted at above, give the customer the ability to do it themselves....
Gave up on the Technicolor Gateway. Bridge mode worked for a short while, but consistently stopped recognizing wifi or internet connectivity. A rep reset things again this morning. While on the phone, wifi was up and running. I stepped away for about 30min, came back and the system was down again. I still had the old RCA Thompson lying around, so I reactivated that one. Gateway goes back to Comcast. Onward.
This is the same problem I have and when they put the Wireless Gateway in bridge mode everything was fine BUT there are 4 ethernet ports on the back of the Wireless Gateway and only 1 will work if it's in bridge mode. I have 2 devices other than the Airport that worked better when connected hardwired (PS3 & VOIP phone).
I've tried putting the Airport in bridge mode while the Wireless Gateway is 'normal' but the only thing that will not work right now is my VPN to my office.
Any suggestions here other than putting the Wireless Gateway in bridge mode and getting a 4 port Apple Airport?
I'm guessing that you're using the airport express. That would only have one or two ethernet ports in the back. I don't believe that it is the same animal as an airport extreme. One is actually a router, while the other is just a network extender , unless I misunderstand them.
Background: I've received the modem upgrade letter and followed the instructions, I did it in 9/13 and I received this Technicolor TC8305C on 11/04/13. After doing some reading on some forums online(including this one), I started to have second thought about this upgrade, I called the Comcast office and was assured that I can return this wireless gateway and get a plain Docsis 3.0 voice and data modem from the service center.
You will NOT believe this, I went over there today and handed them the equipment , and asked if I can get a new docisis 3.0 modem instead.
They said: is your current modem currently working?
I said: Yes.
They said: then what's the fuss?
I said: Comcast office said I can swap a docisis 3.0 one here and I need to do this to keep up with the technology.
They rolled eyes and said: the headquarter did not even send us any docisis 3.0 ones, all we have is the same thing as yours. I can give you the same one if you want to go thru some trouble and have some fun with the activation team. (winking eye)
I said: …..
They laughed and said: Comcast only did this because they wanted to push this wireless gateway on clients, so far as I have heard around here, this is a piece of junk and people hated it. We called it "trouble box" , you are one smart girl who doesn't try to install it right away. Ha ha ha
I said: ……
They said: Ah, they have charged you for the old equipment, I am taking it out now
I said: But the letter said that there would be no unreturned equipment charges
They rolled eyes again and said: you believe their letter?
The Apple Airport Extreme 4G and new 802.11ac 6th gen models work just fine cascaded to the Technicolor *ugh" Comcast wireless gateway with the caveat they the apple devices must be set up to extend the existing network rather than establish a new network. Took me several tries before the Airport would recognize the Technicolor. Be prepared to try several times and you will need to reset the Aiports to factory settings. Cabling would be from port 1 on Technicolor to WAN port on Airport. You must have a wired connection between the two devices. In effect we are using the Airport in bridge mode (DHCP is turned off and the Airport is giving a single IP address from the Technicolor.)
If I am downstairs in our home, I connect to the Technicolor and if upstairs I connect to the Aiport.
IMHO this business of needing to be in bridge mode is not true unless you indeed want to use the Airport to be a true router with DHCP yada yada.
I'm waiting to chat live with a comcast rep now to request brigde mode for my new TC8305C modem. Only reason I got this new device was because we ordered a home phone line (it's been at least 10 years since I've had one). My older comcast modem was simply a modem and I'm using airport extreme base station for routing and wifi. Never had issues. Bummed that Comcast is trying to jam everything into one device.
Ran into this thread via a web search because I got my new TC modem set up as wifi station but my airport extreme will not "extend" the wifi network. I'll have to attempt bridge mode on the comast modem and keep using Airport Extreme as my wifi and router. Will keep you all posted.
