Reception on the ground so far always about 144 Mbit / sec. Stable connection, which also opened jumpy (HD) video enjoyment on your tablet.
However, once several family members in the EC used the same Wi-Fi, it came to -gelegentlich- "hangers" in the video playback.
Now I have the 450e replaced by 1750e.
Reception at the EC NOW speed ca. 300 - 400 Mb / sec. Stable connection, which also allows for judder (HD) video enjoyment on your tablet.
Once NOW several family members on the ground floor Wi-Fi, it came to no -bislang- "hangers" / disorders more in the video playback.
That I still must experience!
Oh yes: the establishment of the 1750e was done quickly and easily via the WPS button. After that the firmware update to version 6.12 and "off we went!"
Just buy it !!!!
Addendum on 10/01/2015: I have the repeater now for over two months in operation nonstop. No failure, no interference, no disconnections, NOTHING! The device works perfectly. Even with multiple wireless users simultaneously, there is now no jerky video / music more dropouts. If someone is looking for a repeater, he should look sure to 1750e!
