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

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.

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.

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.

Think its fair to say you are OK

docentore · 22-04-2014 5:29pm

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 1:10pm

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.

Jeez that's from a year ago,well found m8

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.

03-05-2014 5:56pm

Nice find. I guess the hack is somewhat redundant so.

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

Wonder what the next challenge will be.

dolallyoh · 05-05-2014 9:44am

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 10:47am

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 10:49am

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

In modem or router mode?

dolallyoh · 05-05-2014 7:25pm

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

Is anyone having issues with the 7200 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.

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 12:48pm

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

Does this url work for you? Obviously use your router's ip

Nice find!
