INTEGRATED WIRELESS N MOD

 

The Wifi-card on the Eee is only 802.11b/g, not the latest draft-N. The card is can be easily replaced by removing two screws and unmounting the card from the Mini-PCI Express socket.

After searching around I found a bulk Intel 4965AGN 802.11a/b/g/n Mini PCI-express card for a decent price.

Since 802.11n uses MIMO and spatial multiplexing for better performance and range, it requires from 2 to 4 antennas dependin on the number of transceivers installed.

I had a dead Nintendo Wii which happened to use the same antenna connector as the Intel card.

The connector is named Hirose U.FL. It's hard to get a retail antenna but this one from Oxfordtec seems to be suitable.

Replacing the AzureWare card the new Intel card was done in a swoop.

The new antenna coax cable diameter was a bit smaller and the connector height was lower, but I hope it will perform near or as good as the two other stock Eee antennas.

As you can see below, the new antenna is connected to number "2", I going to swap it out and move it to "3" instead. I want the two good antennas first on "1" and "2", and new one on the "3" connector in case the first two connectors are used for 802.11b/g networks.

As for the antenna, the element was etched on a PCB board with the cable soldered to the center. I stripped much of the dead space to make it fit inside the right side of the display.

The two antennas already in the Eee was mounted with a horizontal polarization. Considering the 802.11n is precoding and postcoding the signal to split the signal over multiple antennas, I decided to mount the with the same polarization and as far from the other antennas as possible.

I had to strip a short length of the coax cable.

It's as flush as the GPS and Bluetooth adapter.

After downloading the latest from Intel's site, extracted the x32-folder and installed the adapter the manual way. Once installed, the default Wireless Network Connection utility found all the nearby wifi-spots.
