Wireless interference

I have a dlink DI-624 g type router - wep enabled, and matching pci and
cardbus antennas on several machines. The router is 25 feet away from the
farthest machine (I live in a 900 sf apartment) and yet the transmission
rates reported by the card utilities rarely exceeds 20 mbs. It sits mostly
at 6-11 or so and disconnects frequently.


Here are my guesses for interference:


One of my neighbors is using a 2.4 ghz cordless.

My 900mhz cordless is bleeding signal.

The logitech bluetooth connection point is interfering.



Questions

1. Will changing channel on the router (from 6 to 7) help?

2. There is a channel selector in the dlink web utility, but it only allows
'6'. How does one change channels on these units?

3. Will the add-on 4db or omnidirectional 5db gain antennas help?

I have a Microsoft bluetooth mouse on my system, and I wonder if it could be
causing my similar problem.

Does anyone know if there is a way to configure the bluetooth device to use
a specific channel? If I could set the mouse to use channel 1 and the wifi
to use channel 6, then I could eliminate the interference (in theory).

Setting the channel is not possible for Bluethooth.
It uses the so called frequency hopping and will change its frequency up to
1600 times per second. Which makes it pretty hard to sniff any packet.

Thanks for the replies.

Well how does one change the channel on the DI-624 router and will it matter
if the bluetooth device is constantly flipping itself?

The dlink config shows a dropdown for channel, but it only contain '6'.
Autoselect is greyed out and "open system authentication" is checked.

You have super G with turbo (either static or dynamic) enabled. Using this
setting, the router uses ALL channels and defaults to 6. Turning off the
turbo mode will allow you to change channels. I had the same problem and
found the information on the Dlink website. Check out this web site and read
everything there as they have info regarding placement of the router and
other issues regarding wireless performance.

Log in to the router, click the advanced tab on top, then click the
performance tab on the left. Scroll to the super G mode and change this to
super G without turbo. You should then be able to change channels.

Also I use a 2.4ghz phone and have no problem with interference. I have the
Dlink DI624 and use super G with dynamic turbo and this setup seems to work
fine.

Thank you TW. Switching off turbo allowed channel 7 to work. Once I
switched, the problem disappeared. : - )

I am happy my information helped, but play with your setup including moving
the router to different locations because enabling the super G with turbo
(either dynamic or static) will definitely increase your wireless
performance. Also check the Dlink website for more info on your DI624. Read
everything there.
