I assume the N300 you have is a DGN type model ? That is not AT&T supported equipment. That is 3rd party, so unfortunately your on your own w/ it.
That being said, unsure as to ping times being that drastic of a change between equipment swaps, but I guess it's possible.
Processing power, QOS settings, firmware issues, who knows. The 2wire has already been phased out and is being replaced w/ a Westell 7550 here in the SE, so if you are waiting for a replacement that's what you will prob get, otherwise check Best Buy, you can still find some leftover 2wire's if that's what you want & just return the other. The only sure fire way to know is to test w/ other equipment & no one can guarantee anything regarding your gaming pings w/ anything else you may be doing on your network, like streaming video.

The problem with your old 2Wire might be the power supply, not the gateway itself (especially if the power supply has "2Wire" written in red ink). AT&T sells replacement power supplies (around $10, as I recall).
