We use the Speedport router already some time in the house, right there were problems actually rare, if there was not WiFi. The WiFi signal is very good near the router, however, takes only a few meters from considerably. In addition, the transfer rate is enormous bad. DSL 6000 works with Lankabel completely, you have eg the download of software the pages of computer magazines, the full download rate in WLAN operation only about half, at full signal strength. All in all we have to say, if you are not the wireless user is, like me, quite a good device, but otherwise not recommended.
