I received my Intel 5350 yesterday. I purchased it from a vendor in Hong Kong from Ebay. I selected this particular vendor because he was providing an antenna along with it. I figured I'd save myself the administrative hassle of making a separate purchase. Out of the packaging, the card looked good, but right away I knew the antenna would not allow me to do this mod. It's only about six inches long, clearly not long enough to make it through the system up to the screen area. Also, it doesn't look like the Tyco antennas you guys are using. The end is not square but instead a much smaller rectangular shape. It actually says 'APPLE' on it. Does anyone have experience with this type of antenna? Also, are the Tyco antennas linked to in an earlier post all long enough to do this mod?
Oh well, I figured I'd install the card and either just use two antennas for the time being or use the third and leave it in the WWAN area like some folks on this thread mentioned. I decided at first to use just two antennas, as I was uneasy just leaving the end of the third just dangling around inside the computer. For those of you who put the third antenna in the WWAN area, did you secure it to the computer? If so, how?
The card installed fine in Ubuntu, and it was very nice to see "No proprietary drivers in use." I'm not a free software zealot, but I can't imagine the Broadcom closed driver working better than the Intel driver.
I could not connect to my network at first. I have my network MAC restricted, and before installing the card I added the MAC address printed on its label to my access list. Ifconfig confirmed that the actual MAC address was different than the one on the label, and once I made the change, I connected fine. I'm slightly concerned about this, as I read that mismatched MAC addresses are a sign of bad things, although my vendor had good Ebay feedback and visual inspection of the card matches pictures of others' cards exactly.
I'm not sure about performance on my G network. There actually seems to be more latency than with the stock card, but that could be in my head. I'm not sure if installing a third antenna would affect this or not.
Anyway, at this point I'm not sure if I should a) leave it as is, b) install the antenna that came with it in to the WWAN area, or c) get a Tyco antenna and go all the way with the mod. Unless performance is unbearable, I don't see going back to the Broadcom, for the driver issue as well as the fact that I now have N capabilities.
