Asp Posted August 20, 2007 Share Posted August 20, 2007 I want to wifi-enable a friend's desktop PC. I've checked the signal in the room with my laptop, and it works, but is not very strong.So I wonder which would give the better performance: a PCI card or a USB dongle?I know of course that each model and brand will be different, but I wonder if there is a general rule.I expect that a PCI card, just because it's bigger and has a bigger antenna, would have better reception. But that's just a guess. There isn't much cost difference, and it only takes a few minutes to install a card, so performance is the only issue for me here.

nitroshift Posted August 20, 2007 Share Posted August 20, 2007 Go for the PCI card, as you can always replace the antenna with a bigger one Link to comment Share on other sites More sharing options...
Shark007 Posted August 20, 2007 Share Posted August 20, 2007 Replacing the antenna will not make up for a lack of raw power.I needed more WiFi power.I already have a Dlink G520 internal PCI card. (very nice)I bought a USB WiFi adapter, EUB 362EXT and have been extremely pleased with my purchase and have not looked back.This little sweetheart has all the power I needed to get the job done.Some info on external antenna upgrades; I hooked these adapters to this antenna.As you can see, this is no usual home wifi system. Using this antenna, I connect to an AP provided by a Linksys WRT54G router that is aprox 2 Kilometers away. I aim the antenna just over the horizon because the AP is beyond it.The G520 could not do this reliably, the USB adapter does it flawlessly.To further add information, having decent drivers is a must. I did a lot of testing with different drivers from different sources.99% of the time you will get the best results from manufacturer supplied drivers but this wasnt the case with the USB adapter and Vista. The manufacturer does supply a driver for 32bit Vista but the driver installed by Microsoft Update has better connectivity.shark Link to comment Share on other sites More sharing options...
ringfinger Posted August 21, 2007 Share Posted August 21, 2007 Good God man! Are you trying to contact the shuttle with that thing? Possibly search for ETs? With an antenna of that size, I don't think the medium really matters, as long as you have the correct power to it be it USB/PCMCIA and enough power for the antenna... who cares. Do what works for you. Link to comment Share on other sites More sharing options...
nitroshift Posted August 21, 2007 Share Posted August 21, 2007 I've got the same type of antenna but it's gain is 40 dB and I use it to connect 2 locations 2 miles away in the city... Link to comment Share on other sites More sharing options...
tain Posted August 22, 2007 Share Posted August 22, 2007 Do you guys have as much luck getting the stronger signals through barriers (walls, buildings, etc) with antennas like that? Distance is one thing, but I more often need the signal to get through especially thick structures over a moderate distance. I've tried some higher-gain antennas and they helped a little, but I haven't tried one of these monstrous ones yet. Link to comment Share on other sites More sharing options...
nitroshift Posted August 23, 2007 Share Posted August 23, 2007 I've got an advantage because the antennas are set up on the roofs of the buidings and see each other directly, no obstructions Link to comment Share on other sites More sharing options...
Asp Posted August 30, 2007 Author Share Posted August 30, 2007 So considering the total lack of consensus, I took the easy option and bought a USB dongle. The signal as feared was rather weak.However, I've just found this amazing page about how to make your own booster for dongles -- from cheap cookware.Poor Man's WiFiSo next weekend I'll be using wifi via a Chinese wok.

tain Posted August 30, 2007 Share Posted August 30, 2007 The term for such things was "cantenna" (can + antenna) in the past, but I don't follow it anymore. Link to comment Share on other sites More sharing options...

Also, as they put a USB dongle at the focus of the reflector, the cable is digital USB, not a traditional radio antenna lead. Link to comment Share on other sites More sharing options...
