I was faced with the choice of the FRITZ! Box 7490 and 7390, and I have finally - opted for the model 7390 - also due to the more favorable price. The main distinguishing feature is the support of the WLAN ac standards for model 7490. However, since we have little equipment at home that can use this standard and also have a repeater in use, can not do anything with WLAN ac, I opted for the FRITZ! Box 7390th The device is extremely easy on the hand and was accomplished in a few minutes. Although I have an O2 / Alice DSL connection with VoIP, I use the telephony functions of the FRITZ! Box. If the login information from the Alice Box are known, together with the establishment of the assigning specific numbers etc. is also very easy and quick. I can not say anything negative about the FRITZ! Box by now is approximately 1 month period of use. The DSL connection is always stable and not even been canceled (by the 24-hourly forcing apart). The Wi-Fi connection also works very well and stable - and on both channels (2.4 GHz and 5 GHz). Granted I use probably only a very small part of the entire range of functions of the FRITZ! Box (answering machine - we have externally, faxing - fax also available externally, FRITZ Media Server - I use a separate Windows Home Server ...), but I want the Device no longer miss. From me, saying an unconditional recommendation to buy the device. If you're lucky and the FRITZ! Box (like me) can get hold of a cheap Amazon True House Deal, would be on top of everything on the unbeatable price / performance ratio!
