Painkiller667 Posted February 1, 2007 Author Share Posted February 1, 2007 Thanks for that informative post. If you wont mind looking it up for my adapter, the model is RT2571WF-on the big chip, and RT2528L on the smaller chip. Thanks! Quote Link to comment Share on other sites More sharing options...

We already know what the other two squares are. Quote Link to comment Share on other sites More sharing options...
Painkiller667 Posted February 2, 2007 Author Share Posted February 2, 2007 hope this helps in case its a little unclear, the second smallest chip says 1207 4099 0628 and the smallest says S79. Thanks again. Quote Link to comment Share on other sites More sharing options...
sneaky_rupert Posted February 3, 2007 Share Posted February 3, 2007 Yeah, the s79 is what I was reffering to. Thats an easy one....s79 is an antenna switch made by Skyworks Solutions. What it does is locks out the receive on the card while you are transmitting so it doesn't backfeed and overload the receiver with full power on transimit. Here is the data sheet FWIW.... http://www.skyworksinc.com/products_display_item.asp?did=612 This confirms that those blobs of solder are definitely your antenna.... Trace the middle pin facing the edge of the board and thats where you are going to want to clean your solder off and solder your connector in....if you still want to that is. If for some reason, it doesnt work out as expected, just resolder the blobs like they were before and you should be ok. A further look at the specs on the chipset reveals that the amplifier is internal....so while it was my mistake that the IC was an amplifier, it is, in fact connected to the antenna.
