802.11G receiving <54 Mbps.

[InlineFour]

my laptop is 802.11g compatible but it's receiving <54 Mpbs. the signal strength is excellent however. is the speed fluctuation normal?

Simply put, just like a wired Ethernet network, you'll never see 100% unless under excellent conditions which is almost never.

If your getting half of that, so roughly 25Mpbs+, or 3+MBps, then your doing very good for 54Mb wireless gear.

I get about 125KB/s streaming from the LAN on my 54g, with WEP 128bit

wired ethernet can achieve 98-99% utilization. There isn't any "theoretical" about it. That's what it can do.

Wireless on the other hand is a whole nutter animal. 22 Mbs thruput is good, about the best 802.11g can do. a is a little higer at 25 Mbs.

OP - change channels and try again. Yes, your speed fluctuation is completely normal. a card/access point will constantly monitor the quality and strength of your connection and adjust accordingly. There are many data rates to 802.11g - 1, 2.5, 5, 11, etc.

"Although 802.11a and 802.11g can support the same bit rates, the throughput of 802.11g is slightly
less that of 802.11a, due to timing parameters included in 802.11g to provide 802.11b compatibility.
If 802.11g and 802.11b clients are using the same AP the maximum throughput of 802.11g clients
falls due to the overhead introduced to support the 802.11b clients."

"Data rate(s) are a matter of standards, environment, and distance. As mentioned, 802.11a provides
data rates at in the range of 6 to 54 Mbps, with rates existing at 6, 9,12,18,24,36,48,54 Mbps.
802.11b at 1, 2, 5.5 an 11 Mbps. 802.11g provide 802.11b compatible rates, with additional rates at
6, 9,12,18,24,36,48,54 Mbps"

from a good paper on wireless...

Sorry, never seen it in the numerous networks I have been around. Maybe a piece of 2 foot patch cable between two new NIC cards could do it. Also I said it could, but almost never.

bluestrobe,

something is wrong then. I constantly have 100 meg links running at 99% for hours at a time. Backups.

What are you doing to test it?

Inline Four if you are referring to End-User installations using Client OS and Entry Level Devices, these are the typical Bandwidth.
