802.11g -- Speed problem -- HELP needed

[freegeeks]

I have a Linksys WAP54G AP with a linksys WPC54G notebook adapter, a WMP54G PCI adapter for my desktop and a WET11 (802.11b) bridge for my xbox. the AP is connected to a 3com 10/100 mbit switch.

I can't get any decent speed on the 2 802.11g adapters and also the bridge is slow.

The highest transfer rate I can get on the 802.11g adapters is 2mbyte (peak) and usually it's between 1,5 and 2mbyte.
The bridge can't get higher then 250 - 300 kbyte.

Even when I'm next to the AP it's still slow (my adapter gives 100% signal strenght and 100% line quality). I tried the 13 different channels and did some tests with and without WEP encryption. I also tried to force the AP and the adapters in 802.11G and 802.11b and it's even worse.

Basically I tried every setting on the AP and the adapters and moved the AP close (3 ft) to the adapters to test.

Any opinions?????

note: transfer tests are done with FTP transfers

Things to try:
-Try disabling some security options?
-Test only with one 11g device (notebook)
-Test only with one 11b device (bridge)
-Flash each device with latest firmware/upgrade
-Turn off all wireless household devices (grabing at anything now).

did that already

did that already
-Test only with one 11b device (bridge)
did that already
-Flash each device with latest firmware/upgrade
good idea - I look into it
-Turn off all wireless household devices (grabing at anything now).
no other wireless devices

Signal Strength can be comprise of noise.

What Linksys Tech support thinks?

I sent an email today -- no response yet
I found a review with the same equipment and in the tests they got significant higher transfers.

802.11g will not run at full speed if there are any 802.11b networks or devices within range. Refer to Tom's Hardware Guide http://www.tomshardware.com/network/20030502/index.html wireless network need to know.

you said mbyte, and that would mean around 16mbit/s. My experience with 802.11g will at best give around 20-23mbit/s. So your result aren't that bad!

I just read a review of my equipment and basically my AP sucks with 802.11b devices. Linksys is working on a firmware upgrade. I guess I should be happy with 10-16 mbit bewteen my 802.11g devices but I'm a bit disappointed. I hoped something like 20 mbit.

from the review

These results were pretty disturbing because they not only indicate that the WAP54G has problems with mixed-mode (802.11b and draft-11g) bandwidth sharing, but that it also does not properly function as an 802.11b-only Access Point!

Fortunately (I think!) Linksys' Wireless-G product manager confirmed my findings and said that they were due to the newer Broadcom AP and client firmware that they were using. This newer firmware improved some of the draft-11g issues that I had found with the BuffaloTech product, but had the not-so-good effects that I was seeing with 802.11b interoperability. He assured me that Linksys was not satisfied with the 11b issues and was hard at work with Broadcom on new firmware to fix them.

I hope that they get the new firmware out soon

Unfortunetly much of the 802.11G was written on a standerd that had not been finalized until recently... I think it was about a month and a half ago. Therefore expect problems between B and G especially from different vendors. Its too bad vendors didn't wait for things to be final, would have saved lots of grief.
