I recently upgraded to VDSL, replacing my old ADSL modem (half bridge mode) and Linksys BEFSX41 router with the Telecom provided Technicolor TG589vn v2. Everything went very well except that the Linksys Media Extenders will no longer connect to my Media Centre PC. 

I tried removing the Technicolor router from the network, and put the BEFSX41 back on and the extenders all happily reconnected.

I am at the end of my network knowledge, but it appears to me that the Technicolor is preventing the connection somehow: Maybe the intrusion detection which I cannot see how to disable? 

Any ideas? I tried to put the Technicolor in bridge mode but could not get it to work with my BEFSX41, however I would prefer to resolve this (if possible) without introducing additional equipment.

I'm guessing the extenders are using multicast to find the media centre and Technicolor's multicast settings are the problem

No guarantees this will work but you could try

1. Take a backup of your config.
2. Telnet to the Technicolor (user:Administrator blank password)
3. Try the following command

ip ifconfig intf=LocalNetwork mcastpromisc=enabled

4. if that works type "saveall" and you're done.
5. If it doesn't work either reboot or just repeat the command with disabled instead of enabled.

If you are comfortable mucking around in the config via telnet some other stuff you could try the following.  You will need to do it for the ports you have your media centre and extenders plugged into (ethport1 = port 1 on the router)

Once again TAKE A BACKUP FIRST

eth bridge ifconfig intf ethport1 mcastfilter disabled igmpsnooping disabled

Thanks for your replies. I entered the commands provided but there is no change.

The Extender says it can't find a network even though it has got its address settings from DHCP. I can ping the unit from the network. I have tried manually setting address settings including changing the default gateway to the Windows Media PC but the result is the same - no connection.

Yes, I am sure it is as the Media Extenders are remote users. I noticed that I cannot make a remote connection either, but used to be able to.

It isn't intrusion detection either. I tried disabling it :-

ids config state=disabled

I am assuming I don't need to reboot the router for any of these changes to take affect.

There is something wrong with the switches in these routers. I had to give a friend an old 100 meg 8 port switch to get their lan working again, their wired printer/scanner thing and a wired computer would not communicate with both plugged into the technicolor, whereas with a switch and then a single uplink to the router it all works perfectly.

This is not the problem in my case, as I only use one port on my router. This is connected to a switch (Allied Telesis AT-GS900) which connects all devices.

Well I just said it another thread but I'm gonna say it again.... these Technicolor/Thomson devices that Telecom supply are garbage they have a history of annoying issues like this, there are many of threads on geekzone ever since Telecom started using them several years ago. Everything from dns issues, nat issues with xbox live and ps3 network, dhcp issues, compatability with mac issues etc.

Most annoyingly the bugs are often fixed by the oem in later firmware yet the oem does not distribute their firmware updates directly because of the white label relationship with ISP's. The fixes never get to users.

I don't see how you can solve this without spending money I'm afraid. I've never seen Telecom distribute a firmware update for these supplied modems.

Bridging which is a good solution (get the Technicolor to be just a dumb modem and do as little as possible) but likely won't work for you because the BEFSX41 doesn't do vlan tagging.  Worse with the small size of the flash rom in that device there is no potential to flash it with open source third party firmware that does do vlan tagging. 

So either you need to replace the BEFSX41 or the Technicolor, suspect replacing the BEFSX41 is going to be cheaper.

There was an option to disable VLANs on the Technicolor. Is this relevant with regard to bridging the BEFSX41?

Would you recommend a router please? I bought the BEFSX1 a long time ago to get a VPN working. Many thanks for the reply - it is always reassuring to know that I am not going insane. I have spent many hours trying to resolve this.

TG589Vn still does VLAN tagging when set up to run in bridge mode using the wizard.
As long as BEFSX41 can terminate PPPoE. (for your previous half-bridge mode setup it would have been on DHCP or something so make sure you've changed those settings)

If this is correct it's just a matter of configuration in your Linksys, maybe try setting up bridging again first in the Technicolor then in the Linksys change the WAN/internet to PPPoE (instead of DHCP).

Telecom PPPoE settings:
Account Name: (leave blank)
Domain Name: (leave blank)
Internet IP Address - Select Get dynamically from ISP
DNS Server Address - Select Get Automatically from ISP
Login user@xtra.co.nz 
Password  abc123
Router MAC Address Use Default Address

Telecom pretty much ignores the login/password and does authentication so they can be anything iirc.
