i got of ebay for a really good price a R310 it is just a standalone AP and one is enough to cover my whole home. it is the only AP on my home network. I just wondered if there was any advantages in changing it to the unleashed firmware or just leave it standalone? i only have one SSID
Sure, you will extend your wireless coverage around the new AP. Using Unleashed firmware is also a good idea, you get a single management interface, and failover of Master AP between them.
