How to increase your WiFi receiving power for PCI card, cheap.

post #1 of 46
Thread Starter 
I just wanted to share this info. I have a Linksys WRT54G and the matching PCI card in my 2nd computer. The 54G is set up on the 2nd floor hooked up directly to computer #1 and the 2nd computer with the PCI WiFi card is on the 1st floor. The best signal I could get before this cheap little mod was 1 bar less then full and sometimes it'd drop even further. I found this coax cable on eBay that allows you to mount the antenna wherever you want away from any metal. IMO, the signal was getting blocked partially by the metal case, seeing that the antenna was screwed directly to the back of the card/case. I attached this cable to the back of the card and then mounted the factory antenna way up high. The signal is at full bars now, all the time. Big improvement. Not bad for a total of $13.00.

Here is the eBay link I purchased it from. I'm sure you could find it elsewhere too. It's called an RP-SMA coax cable. I'm using the 6.5' one. There are all different lengths you can buy if you need something different.

Good idea. They also make cheap antennae and 10 foot cables, but they are a bit more expensive.

FYI, G band wifi runs on 2.4 gigahertz frequency.... RG-6 coax cable is rated to carry siganl frequencies this high... you could've bought six feet at Radio Shack for around $.80-$1\\foot and have used a properly rated barrel connector to mount your antenna to.....

Even cheaper... flash your WRT54G with 3rd party firmware. Boost your transmit power power from 28mW to 84mW.
Once again...

Isn't that against FCC regulations or something?

Naw.. that's just boost power. However, you can overclock the processor!
