The device was made by the operating instructions: You put the CD and the program performs the installation.
The instructions are in German and really good plausible and understandable. However, some steps are relatively complicated (at least I know that from other routers not so): The installation program requires at first, turn off the wireless adapter on the computer, followed by the firewall (you do not do this, the program proceeds discontinued). Then you have to connect via cable to tackle the next steps the router to the computer.
Once connected, but everything worked perfectly: connection with modem, fast connection and acceptable Reich Next (over two floors and several doors).
When you call the web interface (under [...]) is striking: All in English. On the homepage there is a firmware update. After downloading you will find a warning that you should pay attention in any case to the Hardwarebezeichung and number (in this case DIR-645 REV A1) to uphold the warranty or the device could break. Problem: The device has the above-mentioned description, the update is only REV A.
After some weighing up I downloaded the file. To install you must, however, once again the wired router to connect to the computer. After installing the firmware you can begin playing at a German language file.
After the procedure is complete, you must re-enter credentials, however, all - user unfriendly It could hardly.
Conclusion: router works well - operating instructions are easy to understand - for the other device and update the firmware, you should be a little practiced in computer things. Overall, agrees the price-performance ratio.
