7390 works well but WiFi is a bit weak, but not bad enough for me to do anything about it. 7490 is better. 7590 is probably even better.

And are simple to reuse as access points if you can get a second one cheap (which is easy since 2-3 ISP supply them as standard).
The work well with each other handover as if one network

That improves the wifi coverage dramatically :)

It really depends on what you want out of it on how good or not good it is

I've used the 7490 on orcon gig and it smashes that, has good wifi coverage and speeds. 

The FB7590 should be an interesting router, pretty well everything in one box

I like the 160Mhz 11ac allowing 1.7Gbps Wifi 
35b Profile Super Vectoring 300Mbps VDSL2
USB3 ports

Other than that, pretty well same features as the 7490 which had similar features to the 7390 (I use this for VOIP)
Heaps of settings to play with.
VDSL speeds I've found DV130 better at Downstream, but 7390 better at Upstream

1.7Gbps Wifi link will be limited to LAN 1Gbps wired speed, doubt even internal USB3 will do much past 80MBps
Internal antenna's will mean range will be limited, but 7590 is not unpleasant on the eye as some are now with a gazillion antennas 
Super Vectoring unlikely to see that in our lifetime, took Chorus a long time to accept Vectoring, only benefits those within 250m of Cabinet
Possibly biggest downer for the inner geek is lack of Telnet/SSH to tweak, probably why my 7390 is relegated to VOIP and ERL3+DV130 rule supreme, getting hands dirty with setting up manually is what I like.

Still might be a good upgrade for 2Degrees, it does everything, not a world beater but without spending big bucks hard to beat.

I'm another fan of the 7490. It just works and has good wifi coverage around my house.

Thanks for the replies.

Can someone give me more detailed technical information how they have deployed the bridging? Effectively, I want the WAN IP address to show on the router, not the modem.

tanivula: Big fan of the 7490. I use it for a jack of all trades, built in sip client and dect base station (works with basic Panasonic phones as well as feitzfons). Used mine on VDSL and fibre.

Works well, but doesn't have some power user settings/abilities (which I haven't needed)

Pretty much this.  They're good if you want something that just works and does everything.  I think there are better options if you're looking to use a different router and just bridge the fritzbox though...

There is VDSL2 modem only devices like the NV600, but all the data for these and comparible products shows them used in point-to-point situations. At this stage I assume they are unsuited.

FB 7590 (compared to FB7490)

Pros

- Super-Vectoring '35b' (300Mb/s)

- 4x4 MU-MIMO (ac wave 2)

- Band steering

- fast WLAN (ac 5GHz: ~850 Mb/s TX, ~910 Mb/s RX)

- many phone options

- simple operation / setup

Cons

- expensive (compared to other solutions)

- deadly slow USB3.0 (13~17MB/s)

- doesn't accept configuration from FB7490

Like FB7490 not possible without double NAT.
