Had a Fritzbox 7130 or something of 1und1, and had problems from day one. I have a 50MBit line and via wifi but came always good to 15MBit. I must say that the PC is on the 1st floor and the router on the ground floor. I bought my router but because my 1undd1 cheap router has constantly mucking (Latency fluctuated extremely, aborts the connection, etc). 1und1 has still not agreed after several attempts taken the router to Exchange, so I initiative and bought a Fritzbox 7490 and equal to a Netis AC1200 USB dongle for 5GHz WLAN. I can only recommend both explicitly if someone has wifi problems, it is now history. Previously I had to 2,4GHZ Fi just about 15MBit now I've consistently 45mbit (5GHz ---- 2.4 there are about 35Mbit). So it's 3 times as fast as before, and I have no more crashes. I am totally satisfied and I hope that it is now also very many years to come :)
