PAP2 + Wireless-G Router with QoS adapters are 3 in 1: PAP2 + router + wireless connection... This device is absolutely the same as the other one, PAP2 + Router with QoS. The only one difference between them is whether providing wireless connection or not and nothing more.

Both PAP2 + Wireless-G Router with QoS and PAP2 + Router with QoS adapters, in my opinion, are better then just PAP2; because they already have a good router built inside with many features including QoS, which makes voice quality better. Not every router has QoS feature. Therefore, both devices are better than a combination of just a PAP2 and a regular router where QoS is not available.

What is QoS? It is short form of Quality of Service. It gives priority to voice signals in your networking. Let's say you're using internet for a job. When you receive or place a call, the router slows down all your jobs and prioritizes on voice signals. That helps receiving better voice quality.

The device's voice configuration menu is absolutely the same as PAP2, and it's router configuration menu is very similar to Linksys router, WRT54G. My favorite voip adapter (PAP2) and a good wireless router are all in one with PAP2 + Wireless-G Router with QoS adapters. Plus, PAP2 will not work if you go to a friend's house, where there isn't a router. Because PAP2 + Wireless-G Router with QoS adapters are 3 in 1, you don't need to look for a router. This device will work where internet connection is available. PAP2 will only work where both internet connection and a router are available.

PAP2 adapters, for some reasons, don't work well with every router in the market. I remember, some people changed their router just because it didn't work with PAP2. When you have a PAP2 + Wireless-G Router with QoS adapter, you won't have that risk. It is plug-and-play. That's why I believe PAP2 + Wireless-G Router with QoS is better then just PAP2.
