Re: [Announce] bleeding-edge wl1251 wifi driver for Maemo Fremantle

When using these drivers for normal wifi operations it sometimes crashes and wifi doesn't work until i reload the drivers. I cannot reproduce it and it seems to happen randomly and infrequently. dmesg showed this when it occurred just now:

I don't know if that's showing the reason for the wifi dying or just something broken as a result of it.

Re: [Announce] bleeding-edge wl1251 wifi driver for Maemo Fremantle

stlpaul - did you also install the osso-wlan fix? Other than that, I think I have had one or two similar problems, but it's very very rare for me. I typically use the bleeding edge driver as my default wifi driver anyway.

Re: [Announce] bleeding-edge wl1251 wifi driver for Maemo Fremantle

I've used this with no problems in the past... however now when I attempt to

Code:

sh load.sh

the following errors are returned...

Code:

insmod: error inserting 'cfg80211.ko': -1 invalid parameters

insmod: error inserting 'mac80211.ko': -1 Unknown symbol in module

insmod: error inserting 'wl1251.ko': -1 Unknown symbol in module

insmod: error inserting 'wl1251_spi.ko': -1 Unknown symbol in module

ifconfig: SIOCGIFFLAGS: No such device

The same messages are returned if I attempt loading the driver through the FAS script

Argh! What did I do? Your help is appreciated.

Edit: Note, I am running the required modified kernel at 2.6.28.20power46 as the Conky application puts it... sudser & aircrack, etc packages are installed.

Re: [Announce] bleeding-edge wl1251 wifi driver for Maemo Fremantle

tehowe, try doing this before you run load.sh

Make sure you're not connected to any ap point and do this:

Code:

ifconfig wlan0 down

Also make sure you're running the load.sh from the directory that contains those files. :)

Didn't work. I did however see it complain about an additional two insmod insertion errors: compat.ko and rfkill_backport.ko, when I ran load.sh (from its native directory).

Running sudo sh load.sh had it back to the set of errors I posted above.

Removing the wl1251 package and 'reinstalling' it isn't going to be a solution since the problem doesn't appear to be missing or damaged files... would reflashing the power kernel make any sense? Not sure where the solution to this one lies.

Re: [Announce] bleeding-edge wl1251 wifi driver for Maemo Fremantle

It's in the kernel - those messages occur because it can't insert the modules due to header and/or version mismatch. Are you using the default power46, or the modified one posted by lxp? I would assume the former based on the errors.

Re: [Announce] bleeding-edge wl1251 wifi driver for Maemo Fremantle

This does not work! I have given up.

This is what comes of rushing to reinstall absolutely everything in a day when your N900 throws a memory fault - I neglected to unpackage the modules, headers, flash patch etc this time around, and simply copied the directory into place. So, if you're doing this for the first time don't skip this step either after you untar the files...

Code:

* Gain root access



    ~/MyDocs$ sudo gainroot



  * Install customized power kernel



    # cd wl1251-maemo/binary/kernel-power

    # dpkg -i kernel-power_2.6.28-maemo46-wl1_armel.deb

    # dpkg -i kernel-power-headers_2.6.28-maemo46-wl1_armel.deb

Yeah. It also has a habit of not realizing I'm out of wifi range. For example I'll leave home, and an hour later it still thinks I'm connected to my home wifi network. It doesn't happen every time, but every once in a while. It's not a big deal.

I did manage to get gcc, g++ and gdb installed on the N900, however the SDK for maemo 5 doesn't seem to like my desktop nor my laptop (presumably because it warns me that 64-bit is unsupported but gives me the option to try anyway). Unfortunately, this project has now fallen to the back burner since I don't have time to learn about debugging on the N900 (which I'm told is different than debugging on anything else), to get a core file, where to start putting debugging statements in the code, etc. I might get to it one of these days, but don't hold your breath.
