Where possible the highest channel bandwidth is chosen, either 40 or 80MHz depending on the wireless standard. Each WLAN is set to WPA2 personal encryption and a clear channel is chosen. The wireless client used was an Asus G550 laptop with a 2x2 Intel AC7260 wireless card, as an indicator of average performance. I tested with firmware 6.20, and used iPerf to determine the maximum wireless speed at three locations: the next room, immediately upstairs with some furniture in the way, and one room away from immediately upstairs. When I tested, the interface was in English, but the tutorial at the beginning was unhelpfully in German. Then there's Fritz!App media, which allows you to fling media on a connected USB storage device to compatible UPnP devices around the home that are also on the network. There's also graphs showing competing networks and wireless strength. There are other mobile apps - Fritz!App WLAN, for example, includes a QR code reader for easy connection via a QR code generated in the web interface, and you can share your guest login details using a QR code generated in the app, or via NFC. There are easy to read charts showing wireless networks in the area that may interfere with yours. The web UI hasn't changed much since the 7390, with extensive charts, stats and logs helping out should you run into problems. It can also flash for missed calls, unheard messages, and other DECT functions.

An 'info' LED can be configured for different behaviours, including LAN/USB connection, if guest Wi-Fi is on or guests connect, if the Internet connection is active (despite already being a dedicated light for this) or if your Internet traffic quota is exhausted. It's wall mountable, and while it does have a decent smattering of informational LEDs, it doesn't have dedicated LAN activity indicators for each port - you'll have to hit the UI for that.

It's certainly different to everything else on the market, and AVM looks set to follow that trend with an upcoming device looking somewhat like the Nintendo Wii. The 7490 takes the same chassis as the 7390 - unfortunately cheap looking, and looking like a UFO in a retro-futurist illustration from the 60s.
