adhoc mode slower then infrastructure mode ?
« on: January 16, 2004, 11:06:13 am »
Hi,

Using the Socket wifi cf card, I connects to 2 networks.  One to a dlink di-614+ access point (infrastructure mode) and one to a dlink dwl-ag520 nic (adhoc mode).

Other than the mode of connection, other settings are practically identical: WEP, etc.

My observation is that adhoc mode is much slower (gut feels about 10 times) than the infrastructure mode.  Is this inherently so, or perhaps mis-configuration.

Also in adhoc mode, I keep getting the \"The signal is low.\" message every few seconds.

Any advice is most welcome.

I think that answers your question...

I read somewhere that the low signal message is because of issue of signal strength reporting by the driver.

The zaurus is practically sitting next to the nic antenna.

It\'s a bug in Qtopia/Sharp, not in the driver.

Mickeyl,

does that (bug in Qtopia/Sharp) explains the slowness ?
btw, there is no low signal message in infrastructure mode.

Not necessarily. You should check whether the channels are tuned to exactly the same value (there\'s some overlap in 802.11 channels so you might be able to connect to another station although you\'re not on the same channel) and then fire up ethereal (or something else) and check in monitor mode which packets really go over your net.
