To say the same: the Fritz box is technically mature, very well thought out, offers a huge range of functions and has in me equal to work right away.
A great advantage is also that is constantly working on the Fritz box to provide even more features available, such. As the fax feature.
The advantages in detail:
1) excellent user guidance, setting up the Fritz box is really very simple and has in me the same work right away what I was not able to say about the Netgear router!
2.) The Fritzbox replaced ISDN PBX and DSL router, thus creating space and order (by the way, this also saves electricity)
3.) WLAN can easily switched on and off phone
4) the PBX allows the alternative calls via VoIP using fixed dialing rules (ie for example that all international calls may alternatively be performed via VoIP)
5.) stable DSL synchronization, the possible uses of the bandwidth providers really.
6) USB port allows integration an external hard drive or even a printer
7.) faxing (Forward faxes to an entered email address) makes a separate fax machine obsolete
All in all, a very clear Kauftip!
