The network performance is very good and significantly better than the previously used adapters the "AV 500" class. Ok, the comparison is not entirely fair and devolo are also quite expensive rod. Nevertheless ... I am very satisfied, because the transmission speed in the LAN has improved significantly and the external fiber optic connection to the World Wide Web can provide the PCs with full steam ahead thanks to devolo.
Installation is simple. With or without encryption (via a button) - it's that simple. Therefore, the adapters are also in addition to the network cabling with no unnecessary things. The in-house software (Devolo Cockpit) installs quickly and provides information on the connection speed of the adapter.
Impressed by the good results I bought a third adapter and also on the 2nd floor of the house are still good to very good achieved transmission speeds that also play video streams in high resolution easily. Multi-hour stream music from a connected AV receiver is also carried out without complaint.
However, initially dismissed as a coincidence, I realized that the connection to the Internet breaks off repeatedly. The PC then reports that no network connection or no Internet access is available. Sometimes deactivating and activating the network card helps, but often helps only the complete separation of the adapter from the mains. After that everything goes back to normal. Sometimes for hours, sometimes only minutes before the procedure is again due.
Connected the Devolo adapters are in the final analysis with a Fritz box 7390. This loss of network connection occurs with the older adapters (Netgear XAV5001) and not on the Fritzbox provides the wireless clients continue to access the Internet when the devolo's strike. The problem can be focused on the devolo's therefore quite accurately. It almost seems that they go into a kind of standby mode and does not wake up (the error during normal surf sessions occurs).
This is extremely annoying and spoils the otherwise excellent image. A firmware update is not available on the manufacturer's site. Meanwhile, I will live with this shortcoming lack of alternatives. Once there similar performance adapters from other manufacturers, the devolo are unfortunately retired again. Too Bad ...
