Considerable technical problems - currently not recommended

As our current wireless router Unitymedia when WLAN is very weak, we have a wireless router sought to be used as an access point. So far we have used here to their satisfaction a Fritzbox 3370. The downside of 3370 is, however, that this in the 2.4 GHz wireless network is not parallel with the 5 GHz wireless network operates. Both wireless networks can be used as an alternative in 3370. Due to the otherwise good experience with the Fitzbox we therefore fritzbox 3390 ordered because it can operate in parallel in both radio areas. Unfortunately the 3390 but significant problems, at least to date.

The problem is that the Fritzbox 3390 completely of 2.4 and 5 GHz loses in parallel mode again the 2.4 GHz wireless network. The devices not find the wireless network then. Access to the router is possible only in the 5 GHz wireless network - if the connected device supports! The latest firmware 6:01 installed there.

The error occurs especially when it the Fritz box 3390 does not automatically leave, automatically set the radio channels in the wireless areas. The -technical vorgesehene- manual selection of radio channels is but temporarily necessary if the number of devices to access the channel. Moreover is not to be used by the fault of the device which -Also in the Fritzbox technically vorgesehene- disconnection of WLAN per schedule as a result. When using the function to save power at night, the 2.4 GHz radio network was shut down with us in the morning in all cases. It was then only after repeated restart of the Fritz box is available again.

We have the Fritz box after extensive Try various settings, unfortunately, once again returned to Amazon and ordered us the ASUS Wireless Router Rt-AC66uc. Priced slightly higher, but already ready for the AC-radio range, the router is working without any problems. In addition, he radioed in the 2.4 and 5 GHz range (n-region) again significantly faster than the Fritz box.

Note: According to research on the Internet and other Amazon reviews this seems to be currently a general problem and not an isolated case.
