What is the AVM FRITZ!Box 3390?

This is the new flagship in the German networking company's 3000 series. It is the first to offer dual band 802.11n in this range and marks the first major attempt of Fritz!Box (and its curiously placed exclamation mark) to break into the UK after taking nearly 70 per cent of the DSL market in its homeland.

FRITZ!Box 3390: Design

Come in Thunderbird 6! Yes while Fritz!Box and its history may stem from Germany, the design of the 3390 immediately makes us think of 1960s UK cult show Thunderbirds. Its curved lines, matt red and silver paint job and distinctive fins (which hide antennas) certainly give the 3390 the look of a retro space ship and make it a welcome entry into a sector with only a few distinctive designs.

Less interesting is the build quality which, while sturdy, lacks a premium feel. The problem is the chassis is constructed from a series of individual pieces that don't quite fit together as well as they should and produce a slight rattle when tapped (update: having requested a second sample we found this flaw to be a one-off). The 3390 also bizarrely lacks dedicated reboot and power buttons, which means pulling out the power cord is the only way to switch it off. We aren't fans of the five huge green activity LEDs either, which can prove distracting and while their flashing patterns can be adjusted they cannot be dimmed or switched off completely.

On the plus side the 3390 can be wall mounted and it is just interesting enough to look at that this might be an appealing option to those with a bold choice of interior design.

FRITZ!Box 3390: Features

The router's looks got our attention and its feature list isn't bad, either. This isn't a next-gen 802.11ac device, but it does bring the aforementioned 2.4GHz and 5GHz 802.11n to Fritz!Box's 3000 series for the first time. Furthermore, it joins a fairly limited number of routers in integrating a VDSL (100Mb/s) modem making it ideal for fibre optic DSL customers who want an all-in-one product to replace their ISP's modem and router.

Interestingly, the 3390 also integrates a 'Fritz!NAS' which lets you network folders from connected devices directly through the router as it includes a built-in media server. This won't replace a dedicated NAS, but it is a step up from simply plugging in a USB hard drive. That said you can go this latter route too as the 3390 has two USB 2.0 ports and ticks off all the functionality you'd expect from a premium third-party router including WPA/WPA2 and WPS security, Dynamic DNS, IPv6 support and DNLA compatibility.

One downside is there is no dedicated WAN port, so those wanting to use the 3390 with cable broadband will have to give up the dual purpose LAN1 Gigabit Ethernet port, leaving you with just three 10/100/1000 ports for the rest of your wired devices.

I keep looking at Fritzbox stuff, and I love all the DECT and VoIP functionality they include. They seem to be the only router manufacturers who actually do anything different than the standard wifi-plus-four-ethernet-ports number that everybody has been churning out since the Ark. With a Fritzbox I could ditch my VoIP adapter and the DECT base station - result.
BUT - as you point out - they shoot themselves in the foot, at least for cable subscribers. I gather that it is possible to repurpose one of the four ethernet ports to be a WAN port and plug that into the cable modem, but then four LAN ports is already a bare minimum. And they do produce a dedicated cable product, complete with integrated DOCSIS 3 cable modem - but Virgin won't allow you to connect other than their own cable modem to their cable.

All they need to do is to include a WAN ethernet port to allow the modem end to be decoupled from the router. Then I'd look at them seriously.

You're spot on. It seems a strange oversight and there are some odd default settings too (unified SSID, Gigabit Ethernet disabled). But it is an extremely consistent router - just look at how even the transfer rates are on the graphs - and bags of functionality for more advanced users.

Let's see what they have planned for their debut ac product. I understand it isn't far away ;)
