Synology DS213air review: NAS with WiFi
 

The DS213air proves that Synology is capable of creating great software and features, but the decision to use a very limited 2.4 GHz 150 Mbit WiFi adapter unfortunately has a negative impact on the wireless performance. Having a more affordable DS212j along with an affordable router or extra access point is a much better way of having this type of capability.
