WiFi 54 Mbps

If I am xfer file from 54 WiFi Mbps to Computer with 1Gig Lan card with 1Gpbs
what should be Xfer rate?
It is 80211 G Network with PSA-PSK /TKip
Computer and Router is very close.
OS on COmputer is XP SP2
 
The link says "Wireless 802.11g (Super/Booster etc.) Yields 28-42 Mb/sec. (3.5 - 4 MB/sec.)" . That would be the limiting factor and you have 32Mb/s. I assume you have matching super g on your wireless router and source even though you didn't mention it.
Sounds right to me.

Yes, I'd agree also, that link sounds pretty accurate to me. Wifi gives about 32mb on a "good" connection, meaning 3.5-5MB/sec
 
according to link with 1 Gig connection you cannot Xfer file at 32 Mega Bytes per second.
I think i was getting only that much cause Laptop IDE HDD was Maxing out the Xfer Rate.
It may be right for WiFi connection
I also know it is Wrong with 100Mbit Connection too.
I can Xfer file at 14-17 (Depend on Local Network traffic)Mega Bytes on File Xfer
I can take Snap Shop and posted a Pic
 
The speeds mentioned in the page are typical functional speed. I.e. it takes into consideration the average hardware that is employed by End-Users.

32 Mega Bytes per second means a transfer capacity of about 250Mb/sec.

250Mb/sec. is not within the capacity of Wireless connection or 100 Mb/sec. regular NIC.

It can be achieved only by connection two Giga cards.

An average 802.11g connection can maintain 18 - 22Mb/sec., which translates onto 2-4 MB/sec. File transfer.

I know that b and the B are confusing but the info on the linked page is correct.

Yea I was giving ya example of Xfer Rate of 2 Gig Connections.
I just was not sure when it gave the ball park speed for 80211 G would be accurate when they are so off!
I get 2.7 Mega Bytes per second on WiFi Connection I want to make sure that is Normal
Mir 🙂
 
That sounds about right, Mir. Computer hardware almost always boasts the maximum theoretical speed under ideal conditions.
 
Networking is one thing that is pretty clear about exact specifications. It has to adhere to all the standards that allow things to communicate, if it didn't then NO TALKIE-TALKIE.

What's confusing about wireless is there is a big difference between Data Rate (what you send/receive at) and Throughput. It's even more so with wireless because it constantly changes depending on the environment and performance. Wired - not so much.

The link is probably accurate about wireless performance -- it roughly matches my own measurements with standard 802.11g in close proximity.

14-17 MB/s for 100 Mb/s networking is clearly wrong -- 100 Mb/s can only do 12.5 MB/s theoretical at best (and you can't actually hit this theoretical for application data transfer because of overhead). If you're claiming these figures for 100 Mb/s, then something is clearly incorrect / misleading in your tests. Are you actually claiming 14-17 MB/s with 100 Mb/s networking? What are the full details of the test and measurement techniques?

I agree with you that Jack's gigabit material isn't consistent with other findings. But that's gigabit, which has a different set of associated issues, and is not really applicable to this thread.
