Configuration tips for the ubee DDW3611

If you upgraded to DOCSIS 3.0 through Time-Warner Cable, you may be interested in a few configuration settings that were required to get my modem/router to function as well as my previous setup (using a simple Linksys router).

Update: Please review the comments section – tons of people have contributed helpful tips which may help you out if my original post does not.

WPA2: Enable
As part of the default installation, the router only supports WEP 40-bit and 128-bit encryption – this can limit your connectivity options with other devices, is less secure, and more of a pain to deal with the hex keys required to keep for the password. However, through calling tech support they can update your router to support WPA or WPA2 encryption. For me, my previous router was using WPA2, so I requested to enable that.

IP Flood Protection: Off (helpful against DDoS attacks)
With this turned on (the default setting), each machine coming out of standby (phones and computers) had to wait roughly 3 minutes before being able to use the network. This was driving me crazy. All fixed with this turned off.

WAN blocking: Disable
Enable: UPNP
Bridge mode: Off

OK, for the three settings listed above, I can only tell you that this was the final configuration that worked to have my Apple Airport Express to consistently join my network and extend it. (I use this to give my XBOX 360 connectivity in another room as well as stream music to my stereo.) At one point we tried adding the Airport Express’s MAC address to the router and turned on bridge mode (off by default); however, this just prevented the airport express from ever staying connected or being assigned a valid IP. Frankly, I believe most of the trouble was caused by turning on bridge mode. We went around with a number of setting changes until bridge mode was finally turned off. Bottom line is that you may or may not need to make the setting changes above to get your own Airport Express to work.

If you have more to contribute on these settings, feel free to leave a comment below. But I felt I should at least share what worked for me – everything now works as it did previously (plus increased bandwidth of course), but only after about 2 hours on support. Speaking of support: Each of these configuration changes required the help of someone in the “Level 3 Support.” I spoke with Chris and Tim on two different days. Both were quite knowledgeable (and knew each other – it’s not a huge bunch). If I keep having experiences like this, it will become slightly more difficult to spread the hate toward TWC that I shared in my previous post.

    Were you able to get your ROKU to work with the above settings?? I live in Buffalo and they haven’t had DOCSIS 3.0 as long as some of the other systems, so they’re a little bit behind the learning curve. ROKU points at TWC and Vice Versa… I have been a frequent flyer with Tier 3 over the past week, but still to no avail. I would like to keep the old N-Series router in the box and use thiers if possible.

    Thanks! 🙂

    So you are saying you just used the Ubee as the modem and the router? Or did you use it as a bridge?

  • 3 Doug // May 19, 2011 at 8:38 pm

    Yes, I’m using it for everything (router, wifi, modem).

  • 4 Doug // May 20, 2011 at 6:45 am

    Michael – You mean someone else besides me is still using a Roku Soundbridge? You must be using one of their newer things like the Roku HD for video streaming. Amazed if anyone else but me still uses the SoundBridge. But if you are, then I can confirm that it indeed works just fine with this router. I’m encrypting using WPA2 and the old thing hooks up to it just fine.

    Hi Doug

    I have same problems as you did. Where do I find Bridge Mode Off? Is this part of the ubee config or the Apple Extreme config? I am using the Extreme not the Express but I do have an Express I an use also.

    Thanks for posting this


  • 6 Bob // Jun 10, 2011 at 5:26 pm

    Doug, yours are the first useful tips I’ve seen on the ubee 3611 that works w/my iMac AirPort. It now stays connected. However, whenever I try to change to WPS2 security and click “Apply” I get an error; “Error converting one or more entries:

    RADIUS Server IP address is invalid

    Since I’m not using a radius server and did not change the default, Port 1812, I’m at a loss. Any tips. Also, I’m lucky to get 10Mbps upload speed wireless; 45+ via ethernet. Is this typical?

  • 7 Doug // Jun 12, 2011 at 8:32 am

    Dennis – The “bridge mode” setting is not available to me through the web config. This was something that the TWC level 2 tech only had access to. By default, the option would be turned off – as part of the troubleshooting, they turned it on. After a while more, it was determined this was creating a conflict with one of the setting changes that actually DID work. Confusing situation, and one of the reasons you should always change just one setting at a time!

    for the ubee modem

    login:with the last 8 digits of your mac address of modem (“CAPS Required”) password:c0nf1gur3m3

  • 9 Gene // Jul 5, 2011 at 5:34 pm

    If you really want to access the operations mode menu, it’s TlModeChange.asp prefaced with the router ip address. For normal modem usage that would or if already in Bridge mode

  • 10 andromeda // Jul 7, 2011 at 5:40 am

    When I switched my routers and started using Ubee DDW3611 in NAT mode, ROKU couldn’t connect any longer. Enabling WPA2-PSK encryption fixed the problem.

  • 11 Robert // Jul 24, 2011 at 9:45 am

    I just got the roadrunner lightning from bright house. I have 2 xbox 360s and can connect both of them but when i try to run the xbox live connection test the first one i run the test on is fine but when i run the second test on the second machine i get the ole NAT is moderate. I need help please. been on the phone with brighthouse. they sent another tech out to check the problem but couldnt figure it out. i just wanna play xbox live with my brother

  • 12 Doug // Jul 24, 2011 at 5:13 pm

    i have ubee 3611 and nettalk , need to get nettalk to run thru ubee

  • 13 Sam // Jul 25, 2011 at 1:11 pm

    Hi. Thanks for your blog….I used the login info you provided to login and was able to set WPA2-PSK on….I also set it to AES only. Now it works great. Tier3 tech support told me to enable bridge mode which will turn off the primary radio and will allow one to use their own Wireless router. Just an FYI about that …I did not enable bridge mode because I do not want to turn off the primary. I have not doinked around to try and add the bridge and see if I can get a WRT54g with ddrt running…as it is not I am only using the UBEE. Thanks agian foryour posts….using the last six of the mac and c0nf1gur3m3 as the info allowed me to force wpa2-psk…AS DID resetting defaults.

  • 14 Sam // Jul 25, 2011 at 1:17 pm

    Also…once logged in “privilege” mode using the last six of the mac, etc…click on tools..then password and then one can change the privilege mode password….which makes the c0nf1gur3m3 password invalid afterwards…which is what I prefer !

  • 15 Rors // Jul 25, 2011 at 7:26 pm

    Thanks Doug. I upgraded my service and received the Ubee router. For the first few weeks, I kept having the same problem. I would go to a site and the browser would hang and eventually timeout. I had 4 technicians come out and finally the last “high-priority” technician fixed it. Unfortunetly, the modem reset itself and I could figure out the correct configuration. I knew we had disabled the WAN blocking, but that wasn’t the only thing.

    Now the wan blocking is disabled and the IP flood protection is off, everything seems fixed.

  • 16 Jeff // Aug 2, 2011 at 1:10 pm

    Doug, thanks for that tip about the “IP flood protection OFF” setting–that 3 minute delay was driving us nuts!

  • 17 Howard // Aug 13, 2011 at 5:21 pm

    Your information helped me significantly to improve my internet connection performance. I have the same modem/router that was installed by Charter Communications without any documentation. We had terrible performance for several months until I found your site. I used your settings and now it works like a charm! Thanks so much for sharing your knowledge.

  • 18 Sam // Sep 1, 2011 at 1:37 pm

    Just wanted to follow up my situtation….after have Broadband Extreme from TWC using the UBEE 3611 for a couple months now……I HATE the wireless ….every couple of days the wireless radio will be turned off…I will have to go back in and reset settings and then re-enter the wpa2-psk configuration. I have noticed now that if I power cycle the device the same thing will happen.
    I apply settings always and also have power connect to UPS. I have never had so much trouble using WPA2-PSK on a wireless router before but it is obvious to me that there is a big problem with this device. I have noticed others complaining about the same thing.

    So today I purchased another wireless device and am currently in the middle of setting it up on the network with the UBEE in BRIDGE MODE.

    I cant believe TWC would offer such a piece of do do for Wireless.

  • 19 Sam // Sep 12, 2011 at 7:03 am

    I have set up another Wireless N Router with the Ubee in bridge mode. 10 days later all is still well with this new setup. My experience with the Ubee has shown me that the Ubee is great when it is put in bridge mode thus bypassing it. That was my solution anyhow. Thanks for providing this blog. I hope others share their experiences. Thanks again for the resources you are providing her for free !!

  • 20 Tucker // Oct 8, 2011 at 12:15 pm

    Hey I was reading this article because I just got a New Ubee router and I didn’t understand how to log in to it with privilege mode. Hope you can help.

  • 21 Chris // Oct 12, 2011 at 12:51 pm

    I’d like to chime in on the conversation since I just had Road Runner Extreme installed yesterday with the UBEE DDW3611 router/modem. The tech was no help with configuration. He put it in, turned it on and then made sure I could connect to it with my Macbook Pro. He said that they wouldn’t let the techs login for any configuration and that I would have to call support for that.

    Well… Thanks to this thread, I was able to login via “privileged” mode and turn on bridged mode for my wired connections and still configure my wireless as a back up to my main wireless.

    As reference, I have an Apple Airport Extreme as my main router and I’m using a D-Link gaming router (don’t remember the model at the moment) as a secondary access point off the Airport to extend my wifi coverage. Needless to say, I didn’t really need the UBEE acting as a router too.

    Thank you for the info here. It really helped out when Time Warner really ducked out on the installation.

  • 22 Dennis // Nov 10, 2011 at 6:13 am

    I have the DDW3611 wide band from TWC in a one-bedroom apartment. Does anyone know if it has the range to cover the entire small apartment, no matter where I place the router? I am having a dedicated connection installed this Saturday for the router, and want to place the router at the far-end of the apartment, but want to be sure I have a strong signal throughout the entire apartment. Thanks.

  • 23 Dean // Nov 29, 2011 at 5:08 pm

    Just out of curiosity, can anyone confirm their firmware etc.. I just had to have TWC reset my 4 day old Ubee, and want to see if I am using the latest:

    Cable Modem Information
    Cable Modem : DOCSIS 3.0 Compliant
    Boot Code Version : 10.1.2
    Software Version : 8.6.2009
    Hardware Version : 4.31
    CA Key : Installed

  • 24 Rob // Dec 17, 2011 at 5:46 am

    That’s the info my ubee has. I’ve had mine for about 4 months now.

  • 25 scott // Jan 2, 2012 at 12:29 pm

    Great info here!!!! Thank you!!!

  • 26 Emilyy // Jan 14, 2012 at 12:53 am

    I am having trouble with being able to see the network.
    Do you know anything about that?
    I have added the MAC address but it still is not showing up.

  • 27 Dan // Jan 27, 2012 at 4:32 am

    @Dennis: The Ubee DDW3611 has the weakest signal of any router I’ve ever used, including G and N. Setting it up in Bridge Mode and using a better router is the best way to go for me.

  • 28 Patrick // Mar 21, 2012 at 5:50 am

    WOW….I’m in the same boat. TWC hooked me up and left. God forbid you have to call for support. You can lose 2-3 hours waiting on the phone. When you finally get through, they still can’t help you reconfigure the router. They don’t change any of the stock settings. Needless to say they sent out techs that can’t login to the modem. They have to call their tier 3 support group. That was funny as I knew this was going to take along time. Make a long story short…..They suck I sent back their wireless modem and bought my own. It is a Ubee DDW3611 and still can’t connect to any of our devices at home. Came to this form looking for support. Do I have to call TWC and tell them that I want to set my modem to WPA2 inorder for it to work ?

  • 29 Patrick // Mar 23, 2012 at 4:53 am

    Hello ????? Anybody home here any more ? LOL

  • 30 Doug // Mar 30, 2012 at 6:53 am

    Hahaha Patrick. 🙂 So sorry about that. Indeed I am personally less active on this particular thread (although I of course will leave the post here for others to use to share), because we moved and now have been provided a different modem. This time around, I went ahead and followed the common thread of the most successful advice I have noticed in this thread: bypass the basic router they provide using “bridge mode.” In this case, I had the TWC guy just show me how to do this on install, and quickly installed an Apple Airport Extreme. There is a reason Anandtech (my favorite tech review site) says this is the best wifi router out there. Since installing this, and switching to bridge mode, we have had ZERO problems in over a month, and my wifi signal strength and speed has increased dramatically. Yes, you should not have to spend another $180 to get a router when they say you are given one, but it is easily worth it once you start to enjoy truly “always-on” internet with no challenges.

  • 31 Chris // Apr 21, 2012 at 9:52 am

    This blog helped me alot, so let me return the favor. If you have an Ubee cable modem, BYPASS THE BUILT-IN ROUTER! I didn’t even use the wireless portion, but I was experiencing connection drop-outs (but still got full speed – 3.6MB/s) on random devices. I put it on bridge mode, hooked it up to the old wifi router I was using with my old turbo roadrunner service (a $20 V2 WRT54G w/ DD-WRT) and my problems dissappeared completely. When I called TW customer service, I got a tier 1 tech who basically told me that the built-in router was crap, but he didn’t know how to do anything about it. Thanks again.

  • 32 iMiker62 // May 7, 2012 at 6:52 am

    what does everyone think to be better…motorola surfboard or the ubee docsis 3.0 wlcm when using TWC extreme? Any input at all will help…comments, suggestions etc. Thanks in advance!

    Has anyone one used SlingBox with DDW 3611?

  • 35 Aika // Aug 6, 2012 at 6:13 am

    We decided to suppliment our Verozon DSL Service and upgrade our Time Warner Service to include Road Runner .
    We recieve the Kit which include the ubee 3611 but we are unable toeven login to the router access our default gateway. Ulimately we want to be able to tie in our Everfocus DVR and several smart phone/tablets to remotely monitor video..
    We berleive that Port Fowarding or DDNS modifications into the router config may be required.
    The wirelsee portion of the ubee seems to be disables but as it stands we seemed locked out

  • 36 Joseduddy // Aug 7, 2012 at 5:49 pm

    Just upgraded to Time Warner Extreme. They. Mailed DDW 3611. Had to call and have setup ping sent. Then I called tech because it did no activate. Level 3 tech turned it on and I had him turn off the wifi. Using it to connect to Airport Extreme. Getting 30mbps down 5 Mbps up. Running good but wish it had QoS too because I do a lot of FTP.

  • 37 GlobalScan // Sep 7, 2012 at 6:29 pm

    Can’t log into the UBEE using ‘priviliged mode’ at all. I have tried the last 6 or 8 digits of the MAC address and the c0nf1gur3m3 password. BTW which MAC address is it? There are 3 of them on the back of the UBEE DVW3201B Thank you. I am trying to set to bridge mode to work with the XBOX 360 as posted earlier by other people. I also tried the\TIModeChange.asp and it goes nowhere.

  • 38 Naveed // Sep 10, 2012 at 4:14 pm

    Hey Doug (if you’re still looking at this thread) have you posted, or do you know a link to, a guide on how to setup the DDW3611 with Airport Extreme (or Express, which is what I have). Successfully put the device in Bridge mode but the Airport Express would not pick up an IP address or DNS settings.

  • 39 Doug // Sep 10, 2012 at 5:32 pm


    I do look at this thread, but unfortunately don’t have the router anymore. When I moved to our new house we switched to a new router, which I promptly switched to bridge mode as well. I also use an airport extreme, but made the switch to that as I switched routers.

    Anyone else able to help him out?

    I’ve also found TWC tech willing to help get bridge mode working – they didn’t act like it was an unsupported configuration.

  • 40 Dave // Nov 24, 2012 at 7:42 am

    So, I had my Ubee DW3611 in bridge mode for 6 months, but it just slipped back to NAT mode. I logged into priviledged mode and changed it to Bridge mode but it always immediately slips back to NAT mode. Level 3 TW tech came on with same results. Any ideas?

  • 41 Xander // Nov 28, 2012 at 7:03 am

    I have the DVW3201B and am having the same issue with it slipping right back into NAT mode after several months of no issues in Bridge. Glad to see I’m not the only one, but wonder what’s going on??

  • 42 jcarerra // Feb 20, 2013 at 8:51 am

    Could someone answer the previous question:

    BTW which MAC address is it (to use for the privileged login)? There are 3 of them on the back of the UBEE

  • 43 eweissbard // Sep 7, 2013 at 7:09 pm

    I know this is several months late, but try the Cable RF MAC Address, jcarerra.

  • 44 Tim // Sep 8, 2013 at 11:35 pm

    Used the top one and it worked great..

    for those who need it,
    master u/n = the last 8 characters of the rf mac address (sticker on the bottom)

    master p/w = c0nf1gur3m3

    NOTE: after bridging, the initial address of will get you nowhere
    the new login screen address is

    another NOTE: you can type in “”
    (without quotes) after you first login to get to the page where you can set bridge mode.
