    Issue could be to do with IP6 - assuming this is a new connection, then UPC are giving out IP6 addresses only and hence using DS-Lite.
    As far as I know, you cannot bridge the TC7200 if it's using DS-Lite - you need to get switched back to an IP4 address.
    Plenty of posts around here about it. You can request an IP4 address switch through the UPC:Reps here on boards - a number of posters have been sorted out this way.

    True!
    Alan,
    Before bridging attempt I confirmed here on Boards with UPC: reps that I have IPv4.
    And log in to myupc and check if Wi-Free is disabled.

    Try with Linux method, way less hassle than Windows one you described.
    You can burn Linux Mint 17.2 image to USB stick, 4GB is enough, and boot it from stick, use it to bridge TC7200 and not even install it on PC. If Linux command does not work saying you are missing SNMP, type in:
    sudo apt-get install SNMP
    And try bridging again.
    It worked for me.

    Thanks, an excellent suggestion that I haven't thought of. I'll try those and see how it goes.

    Cheers for the suggestion but I made sure to try that last night. There was a few links hovering around boards where it brings you to a webpage and tells you if your on ipv4 or ipv6. It reported that he was using ipv4

    Ok. Well it turns out he does indeed have Wi-Free. Does he need to opt out of this for bridge mode to work?

    Yes, log in to myupc acct and kpt out.
    At first i manager to bridge TC7200 when i still had Wi-Free activated. I forgot about it.
    My setup was working fine for 5 days and suddenly I lost IP and connection to internet.
    UPC was resetting my modem, I was trying to bridge it and losing IP. UPC resetting it again (user hard reset was not helping) and so on. Until finally I asked them to opt out from We-Free. Then it appeared I was already opted out but they didn't know why and on whose request. I knew I was in few days before as I had to use it when I lost my internet.
    Anyway, knowing I have IPv4 and Wi-Free confirmed as disabled, I have it another try and managed to bridge it. Is been few weeks and it's still working.

    Awesome. He just opted out now and it said it would take 72 hours to take effect. So we will give it a shot after that again and report back. Hopefully it will be fixed then.

    I just want to report back that the bridge mode is now successfully working after disabling Wi-Free. No issues!

    I followed my instructions that I wrote previously and his connection has been completely solid both wired/wireless for over a day now. Let's hope it stays that way!

    Thanks guys!

    Updated instructions:

    Pre-instructions:
    1. Make sure Wi-Free is disabled in your UPC account! This can take up to 72 hours to take effect once disabled.
    2. Make sure you are on an IPV4 address and not an IPV6 address. You will need to directly contact UPC to change this.

    Instructions:
    1.Downloaded the SNMP Program from here http://www.snmpsoft.com/freetools/snmpset.html
    2.Placed program on my desktop
    3.Right click on program, click properties, compatibility tab, run as administrator
    4.Pulled out RF cable on TC7200
    5.Held reset button on the TC7200 for 30 seconds using a pin
    6.Logged into the TC7200, turned off firewall (not sure if needed)
    7.Turned off firewall on my windows machine
    8.Connected the Laptop to the TC7200 with a direct connection
    9.Clicked windows button bottom left, typed "cmd" into search bar and hit enter. CMD window appears.
    10.Dragged the SNMP program onto the CMD window. It should create a line with something like "C:/Program File/User/etcetc/SNMP.exe". Don't press enter yet
    11.Copied this line (right click, copy). NOTE: My router address was 192.168.100.1 and not 192.168.0.1 so change in the line of code if needed.
    -v:2c -c:public -r:192.168.0.1 -o:1.3.6.1.4.1.4413.2.2.2.1.7.1.1.0 -tp:int -val:1
    12.Back on the CMD window, after the SNMP.exe part press spacebar, right click and paste (ctrl + v to paste will not work in CMD window).
    13.This should run the program (if not, hit enter), wait a moment, a security window will pop up, hit yes.
    14. Plug the RF cable back into the UPC router.
    15. Double check that the UPC router IP has changed (ipconfig /all). There may be a delay in this. Once it has changed, log into the router and check to make sure there is fewer options available than before.
    16. Unplug your laptop/desktop from your UPC router and directly plug it into your new router.
    17. Plug the UPC router into your new router.
    18.It should work after that! True bridge mode enabled.


  • Registered Users Posts: 180 ✭✭Alan3002


    Ok. So I have run into another issue. My friends bridge mode was working perfectly for a solid week. It randomly cut out yesterday for him and he lost complete internet connection. Upon inspection his UPC router was back out of bridge mode.

    So, he rang them to make sure Wi-Free wasn't enabled. They said it wasn't (it always showed as enabled on UPC router status strangely enough).
    He was still on IPV4 address after a web page check.

    One thing that seems new but I can't remember if it was there before. At the bottom of UPC router status screen, there is information about DS-Lite. I don't remember if this was always there. Any ideas?

    Sorry about blacking out some stuff, not sure what I can show.

    Looks like he has been put onto IPv6/DS-Lite

    Has the firmware upgraded?

    Nope! Firmware is the exact same version.

    I did run one of those "Am I on IPv4 or IPv6" pages though and it returned that he was on IPv4. But I'm not sure how accurate those are?

    Yeah thanks I'll get him to try that.

    He did say he rang the UPC call center and they confirmed that he wasn't on IPv6. Can he still be on DS-Lite and not IPv6?

    DS-Lite is as near we will get to IPv6 for a long time,I'm not up on such things but its basically an IPv4 address wrapped up in an IPv6 address,it gets unwrapped by UPC (I think) and then forwarded on to your IPv4 destination,

    Someone please correct me if I'm wrong?


  • Registered Users Posts: 3 andrewgdotcom


    Under windows, I have found it to be more or less random whether it decides to use ipv6 or ipv4 (if you have both configured) so I wouldn't read too much into that. Unixlike operating systems should consistently prefer ipv6.

    DSlite uses a public, routable ipv6 address - so if you have it you have proper ipv6, no "next best thing" about it. The 'lite' bit of DSlite is the use of an ipv4 NAT-ed private network on top of the native ipv6 transport - kind of a poor man's vpn. Both ipv4 and ipv6 should work transparently to the end user, but you won't be able to run an ipv4 DMZ as you have no public ipv4 address.

    I can see from the screenshot that the router has been assigned a public ipv6, which is expected. You can test if ipv6 works by going to a site that has no ipv4 service, such as ipv6.whatismyv6.com

    BTW, I tried the snmp trick as described above and it is working great so far. I didn't need to do a factory reset on the router, but I did disable the wireless beforehand just in case. Under linux/osx the incantation is slightly different from windows:

    snmpset -v 2c -c public 192.168.0.1 1.3.6.1.4.1.4413.2.2.2.1.7.1.1.0 i 1

    Hey guys,
    If anyone can help here.
    I just cant seem to get a copy of CM Watch 3. Any of the links I follow are bringing up other non related spam stuffs.

    EDIT: Actually got a copy of iReasoning, which was the one I had working previously. However I cant seem to SNMP walk the device.
    Can ping and log into the device, hmmmm any ideas appreciated. laptop and TC7200 firewall deactivated
    If its any help:
    Software Version STD6.02.11
    Hardware Version 2.0.
    Ive tried iReasoning on another SNMP enabled device and got a response so I know its not iReasoning or my laptop?! Have they disabled the abilty to SNMP poll the device now or even the Mib changed?

    Depends, are you connected wired or wireless. Wireless, you may be able to get a cleaner channel and change from 20 to 40MHz spacing, but other that that there isnt much more.
    You can't telnet the modem from what Ive seen recently and I have tried changing the values as my previous post, but no success, No ability to SNMPWalk it.
    Hopefully someone can reply shortly!


  • Registered Users Posts: 3 gsustek


    Hi, what i ment is change the max. speed on cable side! If i have telnet access.
    Can i somehow download sconfiguration file?


  • Registered Users Posts: 884 ✭✭✭zefer


    Just done this and noticed that Thomson defaults to 192.168.100.1 and there is no way to change this when bridged.
    Can my home network still have the IP address scheme as in 192.168.0.x or does home network now have to change to the 100.x subnet? I'd prefer just to add my new router into current addressing scheme

    My Thompson is 192.168.100.1 and my router is 192.168.0.1 with subnet mask of 255.255.254.0. All my devices get 192.168.0.X ip addresses


  • Registered Users Posts: 58 ✭✭drabisan


    @zefer
    It's absolutely ok to have any other subnet in your home LAN as long as it's not 192.168.100.x. Even that will work, but it will be complicated to access your newly bridged Thomson.
    So yes, it's safe to have in your LAN 192.168.0.x!

    How did you do the bridge? Did you use SNMP or the hidden web page?

    I actually changed DNS to 8.8.8.8 to test if it made any difference but no joy.
    Left my bloody laptop in work so can't do much in terms of troubleshooting tonight unfortunately!!

    This has happened to me too. I've just switched on and the Thomson has reset it's config back to non-bridged mode.


  • Registered Users, Registered Users 2 Posts: 413 ✭✭Skittle


    I tried to re-apply the change and it didn't stick after the modem rebooted. Anyone any other suggestions?

    Hmmm, Coincidence?!?!
    I won't be able to try reset the Thomson till tomorrow. Did actually get sent a TC7200 replacement today as power supply went in Thomson other day. Will try bridge both


  • Posts: 0 [Deleted User]


    Same with me. Looks like they've disabled it! :mad:

    I'll try again but if it switches back I'm straight on to them in the morning. If they don't give me a Cisco I'm gone.

    Edit: Confirmed. Removed the RF cable and ran snmpset. PC got an IP of 192.168.100.10. Reconnected the RF cable, modem rebooted and I'm back on 192.168.0.11. Really, really annoyed right now.

    Edit 2: Not working on Cisco either. Looks like it's disabled completely. http://www.boards.ie/vbulletin/showpost.php?p=97534363&postcount=1025

    What do they get out of disabling it? Bar pissing off a lot of customers...

    I really don't know.

    I might be able to pull some strings in work, being a network admin for an IT company and having contacts in UPC Business, but otherwise I guess it's Vodafone VDSL for me.

    Posted this in other thread (missed this thread...)
    Just checked - mine still in bridge mode (TC7200).
    Does it only happen if you do a full reset, or are they forcing a full reset remotely?

    Worried now....


  • Posts: 0 [Deleted User]


    Firmware version hasn't changed for me, still on 6.01.27. So I'd say they've hard-coded the router mode in the DOCSIS configuration file. I had to reboot mine because the upstream wasn't syncing properly. Wish I didn't now. :(

    Took them 19months to lock things down - as you predited back in Mar2014

    What do we lose by being forced to go back to router mode?

    ddns
    dnsmasq
    local vpn server
    external access to local network

    as well as 'stability of vm router' now that it has to do some actual work rather than just be a simple modem.


  • Registered Users, Registered Users 2 Posts: 7,822 ✭✭✭stimpson


    Sorry I didn't put mine on the UPS now.

    Should we start a thread on Ask VM asking for them to enable bridge mode then?

    I'd say go for it. The thing is, with a TC7200 we probably shouldn't have been doing it anyway.

    Still bridged this morning.....
    There are some customers here trialing out the new VM modem/router - don't see much open talk about it, so was wondering would they have to agree to some form of NDA?
    If anyone reading here happens to be one, maybe they could confirm if the device has bridge mode as an option!

  • Registered Users, Registered Users 2 Posts: 2,083 ✭✭✭carbsy


    Had to reboot mine due to dire speeds yesterday evening and can confirm it's gone back to non bridged mode. It doesn't look like a full modem reset as the wireless is still disabled. This would be enabled by default IIRC.

    Eitherway, rubbish speeds still.... hmmmm on the 240 and getting about 40.

    Yeah, definitely not a full reset. My WiFi was still disabled, as was the firewall.


  • Registered Users, Registered Users 2 Posts: 3,278 ✭✭✭techdiver


    When did this start happening?

    I have a TC7200. I had to reboot it on Tuesday night and it is still in bridge mode.


  • Registered Users, Registered Users 2 Posts: 693 ✭✭✭Dave..M


    My TWG was still bridged yesterday, is it just the TC's this is impacting or has anyone else with a TWG also lost bridge? A very unwelcome development to be sure.


  • Registered Users, Registered Users 2 Posts: 7,822 ✭✭✭stimpson


    I've a TWG still bridged but there's no way in rebooting if I can help it.

    Have you rebooted? If not, then don't. As long as you don't reboot the modem you'll probably be OK (until you have to for whatever reason).

    Not yet and I see Carbsy did and lost bridge. This is extremely perplexing, I was looking at buying a new Asus to replace my tired C7 but will have to hold off now which is not ideal as my trusty C7 is getting a bit skittery. I was really hoping the TWG would be forgotten by UPC at this point. I realIy struggle to understand their logic. I wonder do they want to harvest our Irish IPv4 addresses for larger markets (UK?) and chuck us all on DS Lite over here.

    DS Lite .....:eek: but does raise the question
    When you lose bridge mode do you get an IPv4 public address or a DS Lite enabled IPv6 one?

    Still getting IPv4 myself for now.
