[N900] issues with wlan (now after reboot device warm/poor battery)
 

Currently having trouble with the wlan on my N900 at the moment.
It has happened occasionally before but not for a good while.
Normally a reboot fixes, I assume it will this time; but wondering if anybody know why and if it's happened before?

The wlan is set to autoconnect. I locked and secured the N900 before entering a building with an AP I already setup.
Came back to it 2 hours later unlocked a there was a banner "Failed to connect, retry?"
From this point on it will not connect to any wlan connection, although 2G/3G is fine.

sudo ifconfig is missing wlan0 and wmaster.

Doing wlan0 up and wmaster0 up makes them appear in ifconfig again.
Although trying to connect to an AP makes wlan0 and wmaster0 disappear again.

It's not easy to get the full output of ifconfig pasted up here but if it's necessary I can do that.

lo and phonet0 output seems normal.

Thanks for any help in advance.

I've had similar symptoms to those you've experienced. Sometimes when I try to connect to a LAN, it fails then I get the "Failed to connect, retry?" dialogue, but a retry fails. I have 2 LANs and neither can be connected until I reboot.

So I am not alone but why is it happening?

Re: [N900] wlan not working ifconfig not showing wlan0
 

any chance of installing syslog (package: "sysklogd") and posting the syslog somewhere, or just having a look by yourself in case you spot the problem?

although not as useful, you might want to run "dmesg" from the terminal when this happens, and see if it dumps anything that might seem relevant.

Why didn't I think of that.

dmesg is repeating a message over and over.

Ideas?

I suppose you're not using any autodisconnect-like program or special modules for the wlan are you?

One thing you could try is: next time the problem occurs, do, as root, "rmmod wl12xx" and then "modprobe wl12xx", and see if that solves the problem.

Re: [N900] wlan not working ifconfig not showing wlan0
 

the fault is still there, I am purposely trying to do without WLAN so I can help diagnose the problem. If I reboot it disappear and may not appear for another 3 months or more...

wifi switcher.
no autodisconnect installed ever.
Used wlan driver selecter applet, this had been uninstalled via HAM a long time ago.

tried rmmod and modprobe the wlan tries to connect but it doesn't make the issue change in anyway.
I suppose wifi switcher does the same thing and I have tried toggling that a couple of times too.

Seems there maybe a similar bug report.
https://bugs.maemo.org/show_bug.cgi?id=9101#c16

Possibly to do with power saving mode?
Disabled Power saving on my connection it didn't help.

The weird thing about this is it can see the AP in the connection manager but nothing else can see any connections (wifiinfo) etc.

Anybody got any more ideas how diagnose/fix before I reboot?
Could do with wlan connection back.
Thanks

Re: [N900] issues with wlan (now after reboot device warm/poor battery)
 

Ok so I had to reboot as for some unknown reason the device locked up while searching in MyDocs with filebox.

Now since rebooting twice the device has been warm and battery life is poor (full charge used in 4 hours).
Looking at powertop i can see a stupid amount of hardware wake ups.
This has ever happened before so I am not sure if it's releted to the original issue.
