Is this actually correct? Is 11.0 Mbps fast? I have nothing to compare it too.
It depends on what you're doing. For example, a CD-quality MP3 stream from Shoutcast.com is 128 Kbps, or about .12 Mbps. (This is not really a stream per se though. It's downloaded and cached in bursts, and your player, e.g. Winamp, plays back from the cache, not the live stream, while the next burst downloads.) With your connection you can easily stream that and theoretically not experience and drops or lags. I say theoretically because there are many connections along the way, and if one of those is laggy or if your latency is too high then you will "catch up" to the stream and your cache will empty before the next burst is fully downloaded, causing an interruption in the stream. The chain is only as strong as its weakest link.
For downloading from the Internet, 11 Mbps is sufficient for most tasks. Where your LAN bandwidth comes into play is when transferring files between computers within your home network. It would take approximately 12 minutes to transfer one gigabyte of data over 802.11b. The same data over a 54 Mbps 802.11g wireless network would take only two and a half minutes, and if I got 100% of the 108 Mbps "Turbo G" mode offered by my D-Link router, it would all be over in about 75 seconds. Theoretically speaking.
I transferred one gigabyte of data over my 802.11g network today and monitored the throughput using AnalogX NetStatLive
, which told me I was getting a sustained throughput of only 40 Mbps. My wireless signal strength was only about 30 dB, or "very good".
Let's see... I have a .wmv file on my desktop here. Windows media player plays it back at 1514 Kbps, or 1.4 Mbps. It should stream with no problems over your 11 Mbps network. The video dimensions are fairly small though, and the image still looks pixelated. A DVD-quality 640x480 video stream might be a different story. Your mileage may vary.
Hope that answers your question.
EDIT: Regarding the "very good" and "excellent" ratings of your wireless connection, these of course mean nothing. The real measure of your signal strength is measured in dB, and your signal-to-noise ratio. Windows calls my connection "excellent" when I have a signal strength of around 45 dB. Use the utility that came with your wireless adapter, or a third party utility like Netstumbler, to illustrate your wireless connection quality in these terms.
