Hi all,

 

Well I thought I would grab one of these Fritz's as its been a while since I had one and they are just so dam cheap!

 

ADSL & VDSL configs are all good. But I am struggling to get a UFB connection going.

 

The settings are all very straight-forward from the way I see it, but, can't make it work.

 

So the UFB connection is a 200/200 and needs PPPoE on VLAN 10.... very standard.

 

Here is what I did...

Again, seems simple enough. Choose 'External Modem/Router' and 'Make your own Internet Connection'.
I note when I use 'Cable Modem' the only option is to connect with DHCP which is not supported on this connection.

Then I enter the PPPoE credentials... this connection authenticates based on port, but if that fails it will look at user/pass too. (and yes I realise you can see the username. Bares no relevance to anything else except the PPPoE session so not bothered showing it).

 

Speed - Just set it to 200/200. Figure I may need to just oush this way out in case the fritz tries to do something clever and degrades performance. For the record I don't intend on using these for many fibre connections and they will likely all be 100/20's anyway - Its just the office test circuit is 200/200.

 

VLAN ID - Set to 10 as I would on any other consumer router.

 

 

 

I click Apply, it does the little save thing, and then I go back to the main 'Overview' page and wait. The 'Internet' option doesn't come up. When I look at the logs I see this...

Which makes me happy a little bit as it seems to be trying with PPPoE. One thing I do note is that no where in the set up do I actually tell it to do PPPoE which makes me wonder. Looking at the RADIUS logs foir the connection I simply don't see any attempts coming through, which makes me wonder if it is doing the VLAN tagging properly.

 

 

 

Any ideas people?

If you google a bit, you can find out how to get most FritzBoxes to capture all the packets on the WAN interface.  It is a hidden URL,but I am away on holiday and do not have a copy of it with me.  Then load the capture file into WireShark and see exactly what is happening.

You beat me to it. I ended up putting a switch between WAN & ONT and did a packet capture. As suspected packets weren't VLAN tagged.

 

Reset the Fritzbox, re-did the config as above on the clean Fritzbox and it came up right away. I can only assume in my mucking around (i tested on a VDSL circuit before I tried UFB) there was something else going on.

 

So all easy in the end, just put it down to cheap router and average software (as i sort of expected with Fritz).
