download speed when accessing Comcast Internet Service via wireless network from a wireless pclaptop

Compared to accessing the internet service (Comcast at 6Mps) through a
wired desktop that connects to a wirless router, does does the speed
coming into the laptop through home wireless network slower or the
same?

Depending on how fast the network card on the laptop supports, some are
faster then other, I believe. Correct me if I'm wrong.

What I read is that 802.11b is 11Mps and 802.11g is 54 Mps but the
actual rate is half of that.

My question was independent to the Wi-Fi card, does the speed from
comcast slow down? I guess it doesn't.

Correct Mps to Mbps. I would prefer that the stadard usage of the term
is MBps.

I guess, this link answers my question:

Depends on:
1. the speed of the router -- some cheap routers struggle at that speed,
even on wired.
2. the actual speed of the wireless network -- with poor signal, speed
may be low enough to limit Internet speed
3. security -- WEP and WPA can cause speed loss with cheap routers.

Even less than that, and those are maximum speeds that are only
attainable with very good signal (e.g., short distance, no walls).

Comcast speed is unaffected, but overall speed might be limited by the
router or the wireless link.

Mbps = megaBITS per second
MBps = megaBYTES per second
Big difference!

Pay attention mostly to Jeff's posts, and to his reference:
<http://wireless.wikia.com/wiki/Wi-Fi#Performance_and_Speed>

The wikis below should be able to answer most of your wireless
questions.

Or worse.

Since both transmit and receive is on the same frequency, it is not
possible to transmit continuously. In addition to not transmitting
when any other node is transmitting, there are additional time gaps
needed to deal with issues like reflections.

Additionally, if the communication is between 2 nodes that use an
access point, then things will be far worse because every frame of
data is transmitted twice on the channel.

If you have sufficient speed to keep up with whatever burst rate you
get from Comcast, then the answer is no. But do keep in mind that
cable is more "bursty" than something like DSL. You can get a lot of
speed at once, then not much at all another time while one or more
of your neighbors are pulling down a big web page, or MP3, or movie.

As long as the cable mode is attached at the access point or otherwise
reaches it by wire instead of wireless, then radio path to the laptop
should not see the doubling effect of node-to-node through access point.

But you still can see slowdowns due to others using the same, or even
nearby, channel.

802.11b is almost certainly going to slow down those speed bursts you
could get from cable. A good 802.11g installation in a rural location
probably won't.
