intel pro 2200bg wireless cannot connect using AES encryption

Computer Aid Posted on by

This laptop was badly infected, and couldn’t connect to the internet via the 802.11G wifi wireless router.

I remove the infection, but for some reason, the wireless still won’t connect to my office wireless…

In the past, I’ve had problems with the intel proset wireless software, so I uninstall it and use the XP wireless software, but still no go.

I take a closer looks at the windows wireless settings, and I see that it only allows me to select TKIP as the encryption method… and the office wireless uses AES.

I’ve had something similar happen before, but its usually been an 802,11B verses 802.11G incompatibility…

So I try updating the intel driver: yep, there is a newer driver available.

So I install the new driver, reboot, and behold! I can now connect to AES encrypted wireless routers.

ipaq rx4240 wifi confusion (and no AES support!)

Customer needed his new ipaq rx4240 to display pdf files, and to connect to the internet via his wireless router.

Setting up the adobe software was a bit confusing at first (seems like you need to install the software on the PC… and that will setup the sync software to automatically convert pdf documents to “tagged” pdf documents on the ipaq.

Add to that a corrupted installer, and things took a while to sort out.

While waiting for a download, I was asked to try getting the ipaq to connect to the internet via wireless.

I manage to setup most settings, except you can only setup TKIP encryption (but the router had already need setup for AES)… OK, I’ll take a look later…

I finish the PDF work, I start the cumbersome internet explorer application, and I can (eventually!) navigate my way around the internet… entering urls is a real headache!

At least the wireless internet is working (or so I thought)

As I’m about to leave, the customer disconnects the ipaq usb cable, and then notices that he cannot get any more web pages!

I soon realise that the ipaq must have been accessing the internet via the usb link to the laptop.

In the wifi options section, I can see the customers wireless network, but the ipaq seems to continuously connect and disconnect.

Then it dawns on me: Doh! The ipaq is using TKIP!

So I change the router to TKIP (and the laptop), and then everything works smoothly.

I wish more devices (especially new ones) would support AES encryption! Its more secure than the older TKIP
