Basic 802.11g protocol. Also has 4 Ethernet LAN ports on the back and one upstream port. Model DI-524 http://support.dlink.ca/ProductInfo.aspx?m=DI-524 Perfect for an apartment or small home. I used it for email and gaming for years. Mind the scuff marks, it has seen many battles! Theoretical throughput is 45Mbps and it actually attains that fairly reliably. Compare that to recent 802.11n routers which cost $80 and promise 300Mbps or more, but still only deliver around 60Mbps.
