I hear you SeattleHTGuy. Wired is king. But I never have any stuttering with my Cat5 gigabit cable at all.
I had major problems with my router until I installed Tomato USB on my e3000 router, and did a little network management cramming /studying. Spatial Division Multiplexing (SDM) will be the way of the future for high bandwidth wifi. But long story short, I ALWAYS fish a wired connector for my HT because I believe Wifi should be reserved for portable devices. I also had lots of problems with my wifi when I was shopping for baby monitors which did not like all my wifi signals at all. It was actually a serious pain in the butt, just to find a monitor that didnt sound like the girl from the Grudge was going to climb out of the monitor in my house. The whole wifi system needs a good kick in the ass; lets hope 802.11zz or whatever it is called resolves this.
Wifi aside, I found the real problem is that the dominant ISP's (Cox, Comcast, Verizon ( <- non-DC area) in USA have such shoddy infrastructure to support true broadband. The Cox DNS lookup system is a scam. The cynic is me thinks they deliberately make it crappy because they are scared to death of customers being able to get all their TV content over the web AND ONLY PAY FOR THE CHANNELS THEY ACTUALLY WATCH! The Day HBO lets me pay and stream their content over the web without having to get 1000 garbage channels from DirectTV, is the day when I will experience the true joy of living for once.
But hope is on the horizon, a very close friend of mine in hi-tech construction just got poached by Google and without divulging too much company secrets, lets just say BIG things are coming our way in terms of ISP / Broadband / fiber optic. Maybe, just maybe in 10 years we'll be lucky to be where Japan & South Korea were 15 years ago in terms of end-user broadband. Sigh.
Sorry to be so off topic, gsr. But my AVR is working fine and every possible conceivable question/answer to the AVR-4311ci has been bludgeoned to death in the past 494 pages. Allow us a little shop talk. This stuff is interesting, and more importantly, hard to find people with similar interests at the office to talk about it with....
