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

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

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

Karsini cheers

sammyano · 18-04-2014 9:19pm

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 9:23pm

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 9:44pm

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 9:47pm

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 9:59pm

Ok, so now leaving dhcp enabled on wrp400, i will the select Static IP - below is the setup screen if wro400-

Please advise base on the above, thanks in advance

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

Hello Karsini, any idea as to what casing this warning message from upc tc7200-

the mac address presented to them isn't valid for authorization onto the network - however I got this error all the time prior to "converting my thomson" - had a quick look through my logs now on the Thomson and there is no sign of it.

Have you switched to modem only mode or is this prior ?

Nope did not switch to modem only mode, connected another router tc7200 via wan port

sammyano · 21-04-2014 8:25pm

I finally put the TC7200 into bridge mode, but first disabled wireless on both 2.4/5ghz and then turned firewall off.When the TC7200 came back it was in bridge mode. I then connected to the TC7200 using my router WAN port which has DHCP enabled and firewall enabled, however, am seeing these errors - can someone advise if it really mean anything in terms to my setup -

This is really strange, as my TWG870 is on 1.75 and it did dropped of the inet on 17/18th of April. As for today I wasn't able to get it up and running.

Exactly same thing happening - network access denied, only one channel upstream etc.

I rang UPC and they told me it is my modem, I played the "I'm an alien in Eire, it is Easter, please mister upc-man let me use my backup EPC3925". I should have it live today or tomorrow.

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.

I'm pretty sure I've narrowed it all down to the cabling at this point. If the splitter box, or any of the co-ax cables move about, it drops the connection to both internet and tv.

The coax port on my wall, is also very old, and was installed by Cablelink, who were bought by NTL, who became UPC.

Did you see any of these listed warning messages in you log ?

"Map Reject - Not Authorized for Requested Downstream Traffic .."

I've regularly seen that warning for the last 2 years

Mentioned it to UPC plenty of times, and they didn't seem to bothered, as long as I was connected.

I came back home today just to find out that the EPC3925 was reactivated for me. I know speedtest.net tests mean nothing, but I'm getting defo better results than with Thomson. Just to be sure I have activated bridge mode before getting the modem online and I have made config backup.

So bye Thomson, it was fun hacking you.

dolallyoh · 03-05-2014 12:10pm

Tried this on my tc7200 today.

STD6.01.27

Unfortunately the oid isnt present any more, tried private strings also, no difference. Tried setting the oid regardless but it didn't take.

Have you actually tried it and were you able to switch back and forth?

It works fine. You still get wifi options even when in bridge mode but I have disabled mine.

Twas fun though, and guys like you helped a lot of people.

Wonder what the next challenge will be.

dolallyoh · 05-05-2014 8:44am

Quick follow up to this. Since I made the change internet has been dropping out for no good reason. Couldn't diagnose the issue. Eventually dropped back to router mode. Continued to drop. So have popped the rest button which did indeed reset back to original settings ssids etc.

So monitoring at moment, its undeniably a totally **** device. Wifi speeds are laughable and cannot appear to have dual band (ie at same time).

Can we just go out and buy a modem and if so which one ?

Cheers.

Edit: More reliable since the reset. No drops since so far 3 hrs later.

05-05-2014 9:47am

No, you can't replace the modem. UPC have to provision the MAC address of the device and won't provision a device they didn't provide, unless you're on a business package.

dolallyoh · 05-05-2014 9:49am

Might try a business package so. If it was just a mac address they can be faked.

In modem or router mode?

Its currently in router mode. Don't trust it at all in bridge mode.

In the other thread there's some users with Asus routers reporting problems with bridge mode; one seems to have worked around it by changing the router's subnet. Not a bother for me here, been bridged for 4 months now.

Thanks, just going to buy a decent router.

brainzina · 13-05-2014 10:39am

Hello everybody!

Thanks for the great discussion!

Unfortunately nothing of all that worked for me. If I change the MIB it switches back again and I also cannot open the hacked switching site in the webUI.

I have the TC 7200 and really need to find a way of getting it into bridged mode.

Is there any Austrian user (client of UPC Austria) who has had success in doing so? Unfortunately my router is 1 o2 weeks old because I had to change it due to connection problems. So I defenitely have the newest version.

Thanks in advance!

13-05-2014 11:48am

If the MIB changes back by itself then UPC Austria have blocked it. There's actually nothing you can do on your side.

Bear in mind when you first click the switch mode link it will take you to the login screen and not the switch mode screen,

You need to login first then click the link a second time to get to the switch mode screen,

At least thats the only way I can access it here

brainzina · 13-05-2014 9:09pm

I've tried that all. The site is just not there.

But I talked to UPC today and complained about the bad firmware. After a little talk with them I got an "old" "just modem"! So now I have what I want

What did they give you ? Whats your BB speed ?

I purchased a asus 68u to replace me e3000 and confirm that my tc will still not work correctly in bridge mode. It just basically stops communicating with the internet after about 15 mins.

Would be up for asking them for a modem at this stage.

I would totally do that!

I just complained a little bit about the bad firmware and the fact that it's just them not wanting to work in bridge mode (while the callcenter was claiming that bridge mode doesn't work anymore at all) and then they gave me an "old" modem.

dolallyoh · 08-06-2014 9:12am

Brill thanks, I see the "old" modem still works at a fast speed so will ask them for one, cheers !

Absolutely!

Technically it doesn't make a difference if it is a modem or a modem-router it's just UPC policy.

Hi, good to see you got sorted. Is it the old scientific Atlanta modem? What speed are you getting with it?
And could anyone explain why the Thomson switch mode link works for some but not others?
Thanks.

brainzina · 10-06-2014 7:48am

It's a Ubee modem.

I get the normal speed I purchased 75 down, 7,5 up.
