worse than my old wireless repeater

I have changed my Internet cable-DSL on LTE wireless technology. got a new router Easybox LTE 904. Since the router is now in a different place, you had to supply the lower floors, a wireless repeater ago. When my 4 year old FRITZ repeater I had the impression that it does not interacts with the new router (sometimes Verbindungsabbüche). So read Amazon reviews and ordered the Netgear. After the usual fast delivery through Amazon, while unpacking already the first disappointment: its own power supply, so wohhin with the repeater actually part? to be well fixed somehow by the supplied Velcro to the power supply, which ultimately ends up in the wall socket. Ordinary manual? None.
Next, the Koniguration done. Connect According to the sparse instructions easy via USB and has opens automatically in the browser, the configuration mask. But for me, nothing happened. So manually entered into the browser line "Netgear" (Warning! All other network connections previously separate). Once you have reached the configuration menu, the configuration is simple. However, I must say one thing here that my old Fritz repeater is much easier to configure and has more possibilities of setting.
Then the test: The device displays the quality of the connection to the router, I always had poor or average quality, no matter how far I was from entfert router. the best connection I had when I was standing right next to the router. But I do not need a repeater! Ultimately, I have a lot of tried, but in the end my old repeater was better than the new.
Conclusion: Put 6 for the Netgear router.
