Yes, is there?
From what I've gathered:
1.7 ~ Wireless is good, but the stats show a lot of dropped information (Functionality improved)
1.6 ~ Wireless is good, stats are good too. (Has some issues with pc games. Serverlist in CoD4 )
1.8 ~ Wireless for my laptop was fine, but my xbox 360 had a very low rate and thus terrible experience. (Had the latest and best configuration and functionality though. Didn't have to restart for every setting which is lovely.)
I really do hope they make a new one soon.
I miss all the options and ease of use that 1.8 had. But I can't deal with my 360 being unplayable.
