Atheros AR9170 & BackTrack 4

I recently broke out my Netgear WNDA3100 adapter that I bought a while ago to replace my old Netgear WG111 that I used to use for cracking wireless networks. Granted, the WG111 was reliable, but the reasons for the replacement are obvious: the WNDA3100 is dual-band and supports 802.11n. But for beginners who don’t want to shell out as much money nor spend extra time getting a wireless card to work properly, the WG111 is still the best choice.

Spend extra time to get the WNDA3100 to work properly? Yes, it didn’t quite readily work with BT4 (and probably not with other distros running the same kernel version). After doing some searching, I found a thread on backtrack-linux.org’s forum that allows my new adapter to work, with full monitor mode & packet injection capabilities. For a matter of record & for easy searching, I’ll document the directions below.

A Must Have App for the N900

I’m back, for a really brief update… This time to give a shoutout to a new applet for the N900. If you run SSH on your device, this one is a great one for improving security.

It’s called SSH Status and Switcher that allows you to toggle SSHD directly from the status area menu.

Overclocking the N900

Hello everyone.

Today, I bring to you… How to overclock the Nokia N900! Since the first sighting of an overclocked Cortex-A8 processor has appeared, the folks at maemo.org have managed to flash the N900 with customized kernels in order to allow the CPU to be overclocked up to 1.2GHz (DSP up to 500MHz)! But due to liability concerns, only the kernel images of up to 930MHz have been posted.

Technically, the battery life would be less, but the N900 dynamically scales the CPU speed down to 250MHz when it is idle. The custom kernel allows it to go down to 125MHz.

Personally, I have flashed the 850MHz / 450MHz DSP kernel via XTerminal and the phone is definitely a lot snappier & responsive. So far, it’s been stable for me. As with any overclocking, you are on your own and accept the fact that you may cause hardware damage. In no way is anyone liable for such modifications. Period. You have been warned.

The kernels require N900 firmware PR1.1 or greater to run. However, since PR1.2 is coming soon, I highly recommend you restore the stock kernel before upgrading to the newest firmware or you may see some problems. As a side note, these customized kernel images were based off of PR1.1.1 and will almost definitely be incompatible with PR1.2. So once the new firmware has been released, WAIT for a new version of the custom kernels!

If you’re still interested, here’s a link to the guide that jakiman (thanks!) over @ maemo.org has put together: http://talk.maemo.org/showpost.php?p=595582&postcount=774

Props to lehto and titan @ maemo.org for their work in creating these wonderful mods. I will update you guys if anything interesting shows up with the overclocking between now and PR1.2.
