Unfortunately (yet) to use

Recently I switched from my Netgear router in some aspects entäuschenden on a FritzBox 7490. Since I am compelled by the structural situation in my home WLAN and the PC (Windows 7/64 bit) to use I always try to halten.Hierzu this as soon as possible my old WLAN stick should now be replaced by this.
After the very easy installation (WLAN stick briefly stuck in the Fritz box, then be installed in the PC and the drivers directly from the WLAN stick), first copy tests have shown to and from my NAS quite a speed boost.
Unfortunately, also showed soon, very common WLAN interference, so that the simple upload of a website for Gedultsprobe was, you had to call the "gap between the interference" and that proved to be not so easy in a.
Even the installation of the already existing on the AVM side updated driver software (to load this down I had my old wireless stick connect) did not improve.

Thus, this product is currently completely useless. I'll check in a week if there is again an update from AVM, which fixes the problems, otherwise I'll have to send him back. Because then I would rather prove more patience when copying large files as the daily surfing.
