The connection proved very easy. Using the supplied software installation I set up the router in 10 minutes.
Only problem was the release of the external hard drive. Here I am zunächts no progress and therefore have turned me to the TP-Link customer service via e-mail.
Here I was helped in no time. I must say that I am very impressed by the support. Usually it takes more days until you get a reply when requesting technical. Here is the answer always came within 15 minutes. Great.
The only drawback, which is now still is, that the external hard disk after turning off the router again until the next time it needs to be released.
Lt. Statement of support will, however, be fixed in a future firmware versions this shortcoming.
Then I have the perfect router for me.
