Serge replied and pointed me here where I grabbed the overclock wifi module. I'm sorry to say, I don't see much difference. I'm now seeing an upper cap of around 300 kB/s and lower cap of 30 kB/s.
This driver is provided 'as is' and without any warranty. While I successfully use this driver myself on my Nokia 770, it is not known if it makes the hardware operate out of its specifications. ================================================== ============================= More details about this driver can be found here: https://garage.maemo.org/pipermail/c...ry/000019.html 15mhz version is probably a safe and reliable choice. 21mhz is the highest clock frequency which seems to work on the device (with some glitches that need workarounds), so using it may be much more risky. ================================================== ============================== You can load optimized wlan driver and test it by doing the following: 1. copy the modified driver cx3110x-optimized-15mhz.ko somewhere to your device 2. login as root 3. run the following commands in the directory with cx3110x-optimized-15mhz.ko: rmmod cx3110x insmod cx3110x-optimized-15mhz.ko chroot /mnt/initfs /usr/bin/wlan-cal 4. connect to wireless network 5. test performance/stability of your network connection To ensure that the driver has really loaded, you can check 'dmesg' log. You should see something like this after loading driver: [ 64.257110] McBSP2: freq_limit=16MHz, base_freq=63MHz, div=3 (15.7MHz) [ 64.257659] Loading 3825.arm firmware [ 64.453460] (c)opyright 2004 Conexant
