Description Ralph Angenendt (reporter) 2009-12-03 02:21:12 UTC

SOFTWARE VERSION:

1.2009.42-11

EXACT STEPS LEADING TO PROBLEM: 

When using WLAN, the connection gets dropped after a while. If automatic
connection to 3G networks is enabled, the device will connect to the 3G
network.

The N900 connects against a Linksys WRT610N access point. 

EXPECTED OUTCOME:

N900 stays connected as long as it is in reach of said Router.

ACTUAL OUTCOME:

N900 gets disconnected.

REPRODUCIBILITY:

Always after around 10 to 15 minutes.

OTHER COMMENTS:

I tried fiddling with the WLAN options for that connections - e.g. setting
powersaving to Medium instead of Strongest. The outcome is still the same.

Created an attachment (id=1657) [details]
dmesg from when the connection gets dropped

The connection drops at

[20703.080474] slide (GPIO 71) is now closed

The lines before show that the connection has been opened, associated and
authenticated.

Thanks for reporting this.

Kalle, I highly assume that this is the same issue as int-140075 (N900 gets
deauthenticated sometimes when it sends data after being in idle mode for some
time). Do you agree or is more info needed here?

Did you also try to completely disable Power Saving Mode?
(Also see bug 5708.)

Yes, disabling power saving seems to fix the issue (no disconnects during the
last 90 minutes).
