[maemo-developers] [maemo-developers] Unreliable Large Network Transfers

[From: Mike Lococo]

Hi Folks,

I posted an earlier version of this comment on maemo-users a few days 
ago and got one confirmation from another person experiencing similar 
behavior, but no useful advice (they simply stopped using the network 
for transfers)... so I thought I'd try again here.

I'm finding that large (>200MB) transfers of data via the wifi network 
are extremely unreliable.  They start out running at a reasonable speed 
(350KB/sec-600KB/sec), but within a few moments slow to less than 
100KB/sec.  The rates become very erratic, and the device GUI becomes 
very unresponsive.

   I've reproduced the problem in a variety of scenarios:

    - unison over SSH with a variety of connection settings
    - wget from a local webserver
    - using the bundled webbrowser from a local webserver
    - All of the above while connected to my wrt54gc access point at home
      on which I'm the only user, have strong signal levels, and no
      history of interference problems.
    - All of the above on whatever enterprise level access points are
      used in the Cornell University wireless infrastructure.  Again,
      strong signals, familiar locations, no history of interference.
    - All of the above in situations in which other wireless clients are
      able run the same download at high-speed without mishap.

Does anyone have advice about how I could further troubleshoot or 
isolate this issue?  Is anyone pushing substantial amounts of data over 
the network without these problems?

Thanks in advance for any advice,
Mike
