I have a choice between a Linksys WRT54GS v2.0 or v4. I have the v4 running with Firmware Version : v4.70.8, Hyperwrt 2.1b1 + Thibor14 and is running just fine. My question is whether the extra flash (8mb) and memory (32 mb) that the v2 has is of any value to QoS processing and overall throughput. That is all I'm using the router for right now. I'm not even using the wireless but I may later. My main concern is for the best possible voice connection. Thanks - Mark.
