House is relatively large 2 story. I use the DIR-655 on the main floor for my laptop (work), wireless printer and another work desktop. It also serves as the router for the entire home network. Currently have an old wbr-2310 on the second floor configured as an access point and serving kids laptop, 2 ipod touches, a Wii and an Xbox 360. The wbr-2310 appear to have stopped working. So....
Looking to buy something used off of ebay. I've seen several 655's that are HW version A2. What's the difference between version A2 and version A4?
Any other suggestions for viable replacement?
Thanks.
