I have "only" a Fritz! Box WLAN 7270 from the same manufacturer, which is why, of course, I can not discuss the use of the FRITZ! WLAN Repeater N / G with products from other manufacturers.
At home (detached) solid walls and ceilings are made of concrete between the Fritz! Box (Keller) and my laptop in the 1st or 2nd floor. So far, the wireless reception was on the 1st floor acceptable and miserable on the 2nd floor - to say nothing of the new n standard with 300 Mbits as the 7270 rules him completely.
Everything has changed.
! The FRITZ! WLAN Repeater N / G is small, visually very elegant and can be set up baby easy: a touch of a button (on the almost de rigueur belonging touchscreen) - and he recognized my box and WPA2 securely connected to her. Now he hangs exposed, yet elegant and unobtrusive to an outlet in the staircase (nice side effect as a night light). Zero cables, null ugly, clunky box & antenna.
The transmission rate is high (with 1 & 1 you do not get anyway innately promised the highest transfer rate) and especially stable. No disconnections, fluctuations in rate and other faxing. Mind. 54 M / bits are always there. Finally surfing and doing the work also on the 2nd floor fun !!!
Who has an older modem, you need to also not have to worry, because the repeater also controls the standards 802.11g, b, or a - as I said, I can not verify how it cooperates with other brands.
Another function is the transfer of music data on the repeater on the stereo, because it is equipped with a digital (S / P-DIF) and analog (3.5 mm jack) Audio output and a VHF mini transmitters (FM transmitter). I personally do not need this function - here are two stereos in the rooms of the adults.
My Conclusion:
Anyone looking for a reliable, mature and meaningful brand designed and state-of-the-art repeater needs to access here. The company AVM (no surreptitious advertising!) Is also known for product maintenance and service even in older models is on their priority list. So far I have two boxes this company - and never had problems with them. On the contrary, AVM constantly brings out new firmwares with new features for their products.
I think you can go wrong here nothing, and the price is completely justified (but certainly fall).
Hope to have helped you.
