Did not bother me, only that there was no option to disable the WLAN night. After a short Google search has been found that the device is supported by the alternative firmware DD-WRT. Again briefly read and flashed the correct version (normally via firmware upgrade, detailed instructions there is heaps to Google), made all the settings (now even in German!) And the router again ran without problems as an access point.
The setting of the wireless timing turned out to be a bit more difficult, however, because it is by default not "included" in DD-WRT on this router. However, this can still be activated, so is now disabled depending on the day at different times-Fi and morning reactivated by script in a command line. Outstanding!
In addition, other features are offered, so that the router also our dear Fritz! Box hardly inferior.
Time spent on everything with me (although technically savvy, but in the field as Router Access Point & alternative firmware without any prior knowledge -> google) about 1h.
Also the power consumption is very good (no heat). Measured in continuous operation 2-3W, so that the demand for electricity in the year with about 5 can be covered.
For the price really a great device that has earned the small modifications the full 5 stars!
