I just installed one of these at home, and it’s great. It reminds me of OpenWRT, the open source router firmware, in that it allows you to turn the router into a WiFi client, a wireless bridge, an access point, or a range extender. It’s super-cheap at around $25, and extremely easy to configure with the provided configuration wizard.
Anyone who knows what the different modes are, and how to configure an access point, can set it up in ten minutes.
It even does VLANs! Well, not really – it allows up to four SSIDs and will send each one to a different VLAN. That’s the bare minimum needed to set up access points with guest and private networks. So you can combine that with a lower-end smart switch, and do a little enterprise-style WiFi on a small budget.
It even supports “Passive POE”, which is just a power injector device. The device doesn’t support any of the standard power-over-ethernet standards.
