UPC Thomson TWG-870U & Technicolor TC7200 - Enabling "Cable modem" mode - basic guide

Yeah, tried that. I am not getting the numbers in the same range as before like this
1.3.6.1.4.1.4413.2.2.2.1.7.1.1.0
The last time I could see my passwords and stuff like that but when I right click on the number and changed the interger to 1, it would not save.
Can I type the above number into the box and get it to search for that?
Sorry about the bother but I am a compulsive tinkerer and have to interfere with this and get it working. Hitting the sack now. Enough for one night...will try again fresh tomorrow.

Could not get it working myself the first time I tried it, but have another go with a clear head and maybe follow this sequence

- power down tc7200
- disconnect upc coaxial cable
- power up tc7200
- connect your pc to tc7200 using cable only (switch off wireless on your pc to be sure)
- login to public address 192.168.100.1
- switch off firewall - make sure to save
- try CM again to make the change
the tc7200 should reboot
- reconnect upc coaxial cable
- disconnect/reconnect your pc from the tc7200
- login to public address 192.168.100.1 and check the menus - if you are in bridge mode then some menus will be gone or just displaying zeros.
You might have to reboot tc7200 to be sure
- check that your pc now has a public ip address rather that a local 192.168.x.x. address
- reboot tc7200 and check again

Notes
I could never get CM to work properly, but did get MIBBROWSER to at least read the data. A number of posters have used both of these methods and they work. I myself used the linux method to make the change by booting up a linux live cd and running the snmpset command line option.

As regards new firmware effecting things, I'm not sure but dloob posted a few days ago that he/she switched okay using the linux snmpset method

Fair dues Westie for your time and effort.
I will try that later and report back on here.

Pov06 · 09-04-2014 8:26pm

It is a lot easier to do if you have access to a Linux machine as it's only 1 single command. The whole process takes 2 seconds

Looks like I got it into modem mode last night.
I did see a box saying integer accepted or something like that but did not notice the modem rebooting.
I have a public ip and router is working on both freqs. Some, notably the Advanced button id gone.
I cannot get into the routers interface through the modem. Is this the norm?
I plugged it into the computers network socket to access the interface to turn on radios.
It seems to work with modem (now) to router cable plugged into one of the four ethernet sockets
or plugged into the internet socket. Which one is right?
Speed on laptop on wireless is way down around 7 Mbps
Anyway, working now. CCTV sending live pics again too.

You should be able to access the modem via http://192.168.100.1 after the change. The correct way to hook it up is to attach all of your devices to the router and connect the WAN (or internet) port of the router to one of the LAN ports on the TC7200. Then configure any port forwarding rules on your new router.

Good to hear. As Karsini said you should be doing all your config/connections on your router including wireless. Your tc7200 is now just a modem and should be used for nothing else except the phone.

capailldubh · 10-04-2014 8:53am

Yoked it all up as advised by Karsini and I can access both modem and router interfaces. Got 70Mbps this am on wireless via my Netgear so happy out.
Simple when you know how ;-)

ondafly · 16-04-2014 5:59pm

right end of my tether with UPC, came home to find out they disabled my Wifi in an attempt to turn off horizon wifi-free rubbish.

Can anyone confirm that this enable mode, is possible when your Thomson is on STBA.01.75

sammyano · 17-04-2014 7:15pm

Guys - just got my new wifi modem from UPC TC7200.u, and looking for suggestions for a new router that supports wireless n networks with phone ports for my voip connection [Blueface]. Currently using the Cisco WRP400, so would like to get a new router with phone ports and then bridge the TC7200 and just use it as a modem only.

thanks

ondafly · 18-04-2014 4:00pm

Just a big thank you to the docentore for this - I reached the end of my tether with UPC last night, after the modem rebooted itself each time I attempted to stream to twitch.tv - so this morning went straight out and bought the Asus Dark Knight , grabbed a laptop and changed the MIB entry to have a modem only Thomson.

Modem rebooted as predicted and my laptop was out on the big bad world. I then setup the Asus, and reconnected everything, the modem stopped working briefly, but after a reboot and a few speed tests, all seems well.

ondafly · 18-04-2014 5:57pm

looks like I spoke too soon. back to my same problem - upstream channel drops completely. I've rebooted 3 times now and its not come back. might have to revert my changes

Sounds like you might have a fault there, what's the upstream transmit power?

ondafly · 18-04-2014 6:03pm

Network Access - denied,

as for the power levels ;

only getting 1 channel - QAM16 , channel 3 , @ 45.2 dBmV

I used to have this problem a lot where I live. Seemed to be a local fault but hasn't happened since Christmas.

ondafly · 18-04-2014 6:17pm

did a bit more tinkering, there was no chance of me reverting my changes

IT people go forward, not backward

Anyway, I've removed the 2 way splitter from the UPC connection to the modem & tvbox and wired straight to the modem, and I'm back online.

My SNR and power stats :

Looks like I'm speaking far too soon a lot today. Feckin upstream channel has dropped again.

edit

pulled the modem out again, plugged it in away from the TV etc and I'm back online - with slightly different stats

The most important part is, I've rebooted this thing 9 or 10 times and the modem mode hasn't changed

sammyano · 18-04-2014 8:00pm

Ondafly, what version was TC7200 when you changed to modem mode only, just wanted to know if it's working for 01.27?

I'm actually using the Thomson TWG-870U

Software Version STBA.01.75

sammyano · 18-04-2014 8:40pm

Ok cheers, thought it was tc200, as am thinking of doing same

Definitely works on 01.27 because I did it on mine with this version. You need to disconnect the coaxial cable though.

sammyano · 18-04-2014 9:25pm

Karsini cheers

sammyano · 18-04-2014 10:19pm

Guys, can someone please advise the right way to use both tc7200 and my existing ATA/router (Cisco wrp400) together without changing tc7200 to modem mode. Here's what I did- I turned off wireless on tc7200 and disabled dhcp and then plugged in Ethernet cable to the LAN port of tc6200 and the other end to the wan port of my wrp400, so it will continue to give dhcp to all my devices and connect to voip providers as my main wireless router. Is there a better settings or setup to use?

18-04-2014 10:23pm

If you don't want to bridge it, then you will need to assign your router's WAN port a static IP address in the TC7200's range. Make sure that the two routers are not on the same subnet. Then go into the DMZ section on the TC7200 and specify this address. If you don't do this, you could run into port forwarding problems, especially with the VoIP side.

sammyano · 18-04-2014 10:44pm

Karsini cheers, but the wro400 is set to enable dhcp where as it was disable in tc7200, do I then need to disable dhcp on wrp400 and enable it on tc7200 before assigning static IP to the wro400?

18-04-2014 10:47pm

No, you have that correct. Leave DHCP enabled on your WRP400 and disable it on the TC7200. In all honesty it shouldn't really matter if DHCP is left on on the TC7200 as well, provided that it is connected to the WAN port on the WRP400. The DHCP request isn't carried through the firewall.

sammyano · 18-04-2014 10:59pm

Ok, so now leaving dhcp enabled on wrp400, i will the select Static IP - below is the setup screen if wro400-
Internet Setup
Internet IP Address : . . .
Subnet Mask : . . .
Default Gateway : . . .
DNS 1 : . . .
DNS 2 : . . .
DNS 3 : . . .
Network Setup-
Local IP Address: the router default IP
Subnet mask:255:255:255:0
Please advise base on the above, thanks in advance

18-04-2014 11:03pm

Internet Setup
Internet IP Address : . . . 192.168.0.254
Subnet Mask : . . . 255.255.255.0
Default Gateway : . . . 192.168.0.1
DNS 1 : . . . 89.101.160.4
DNS 2 : . . . 89.101.160.5
DNS 3 : . . .
Network Setup-
Local IP Address: the router default IP
Subnet mask:255:255:255:0

After this, you'd then log into the TC7200 and enter 192.168.0.254 into the DMZ section.
