But teething problems, then problems

I bought the switch in order in our house to rewire a patch panel in a flush-mounted cabinet. Going from patch panel from CAT7 installation cable in all rooms spread over 3 floors. To have the best possible Wi-Fi coverage in the house, I wanted to use my existing Apple AirPort Extreme and my two co-existing Apple Time Capsules as access points. After wiring short durchgemessen the Leitugen and then install the switch. When I then connected the access point (bridge mode, the DHCP server disabled) have given me all the devices shown that no network connection is available. After much back and forth and days of research I then found out that there are probably problems with the increasingly supported by the switch IEEE 802.3az EEE. Now that I have pressed the corresponding button on the switch to disable this feature, I had the APs still reset again and then reconfigure. Unfortunately, one searches in vain similar indications or problem descriptions, so this was unloading some review. Since the switch works without problems and are neither beeps or anything else from him.
