Hi,
I'll begin to explain at the point where my wireless environment is working to my satisfaction.
I will notice delays while downloading YouTube video. I also will notice delays when I view or log on to various web sites. In both cases the delays come in "spurts". An example: while down loading a YouTube video, a piece of video is displayed, then pauses, then starts again with the audio portion acts the same way. I then run "speedTest". It shows my ping time is 230 ms. My upload is 2mb, download .97mb.
I power off both the vendor (Time Warner) modem and my Linksys router. I use a wireless connection. After a few minutes I turn the modem on, not the router. I wait until I see the telephone lights (we also have our phone service through Time Warner). The phone indicator lights are the last to "come up" during the power on process. At that point I turn on the Linksys router. After several seconds, I see that the adapter in my PC has synced to the router with a good 4 or 5 bar signal.
I run SpeedTest. Ping is 111, download in 10mb, upload is .98 Downloading YouTube videos are fast They run as expected. Displaying web sites are excellent. I might run good for a few to several days when the cycle begins again. Calling Time Warner support: they give me the same process I've used. This problem existed before I had my Droid2. My network uses security. My browser is Firefox.
