I was able to do this to my Asus G71GX gaming laptop. Only thing was in order to get to the spot I wanted my antenna, I had to fully disassemble the laptop. But it was fun.

HI interested indeed of your usb wifi amp so it doesnt come already usb? but yes instructions would be great.
xxgemini (author)  D33ZZ7 years ago
Hey guys... Well I havent got around to do usb amp isble. So I just tell ya how in words. Its realy simple. The amp came with a wall wart power adaptor, but thats not to travel friendly. Usb plugs have @ 5.0v available to power things. You can pick up an amp from Ebay for @ $60.00. I used a 1watt amp. Then you need a usb plug, I just choped 12" off an old usb mouse. So in the usb plug red is positive and black is obviously negative. They are the 2 outer most pins. The 2 inner data ones we wont be using. Now open up the amp with the 2 screws, and very carefully remove the power plug jack. I used a dremel. there will be 3 solder points under the jack. If I remember correctly the far left is positive and the middle is negative. I just touched the wires to it for a second till the amp light came on to find the right pin. Now feed the usb cable through the hole where the power jack used to be and tie a knot so it wont get pulled out. Now solder the Red and Black Usb wires to the solder pads on the amp. Close her back up and shes ready to go :) I used it at BWI airport the other day and picked up like four pages of routers....lol
hi there, I've been planing on doing this to my " inspiron 1525 " but would like to know if a twin antenna set up would work better.
how much does this effect ur battery life? if it drains it quickly you might wanna look at this mod as well...
www.instructables.com/id/Increase-the-capacity-runtime-of-your-laptop-bat/

also would 2 antennas be beneficial? like the routers that have 2? 
That is a great modification that you have done. It was the inspiration for performing a similar mod to a dell inspiron 5150. The antenna mod works great.
I ordered a 1 watt broadband amp to use with the laptop and it also works great but I'm wondering about the specs on the amp that you used as the wall adapter is 6vdc @ 2000 ma, this power requirement far exceeds usb power. Can the amp be used at lower power? Right now I'm thinking about making an external battery pack with a charger for portability.
Wish me luck and again great work

How do you supply energy to the amplifier through USB cable?

What does the end of the antenna look like?. I found a bunch on ebay that look like it but I need to know if the RP-SMA connector will fit in the end of it. Can you take a pic or something. Thanks

I successfully completed the mod on my Compaq Presario.  However, I received no increase in signal compared to the factory setup.  At least now I have an external point to possibly hook up an amplifier.

I have a question, can you remove this antenna and still get reception? if so, is it better or equal to the original built in antenna? Thanks for the help, Jeff

I added a U.FL jack to my Inspiron 1720. Drill one hole, plug it into the wireless card, reassemble the computer. Tada. I am quite interested in your wifi amplifier though!

I have a d link airplus DWL-630 and it has no places to plug in an antenna, Would an antenna even work in conjunction with the card by plugging it into a usb port, if so what kind. What else could I do please help

dude yus a bad a. ss thank you for the Instructable ( got me some tools and a antenna)

Just a thought, why hack the amp power plug. might be easier to take the male plug off the power supply and put it at the end of the usb cable you use. Think?

I have a Mac Mini and the WiFi reception is very poor. I opened it up and found the WiFi card. It had two connectors for antennas. One of the connectors was used by the Mac and it used the horizontal metal top of the Mac as its antenna (it doesn't work well). I wanted to add a second antenna of high gain so I could use my home router located in another room. The problem is,no one I spoke to in electronics shops that sold antennas could identify the little connectors used by the WiFi card. Your instructable identified it as a "U.FL Connector". Where did you get the MALE U.FL CONNECTOR, and the super thin shielded coaxial cable. And lastly how did you connect it all together using the Reverse Polarity-SMA connector. Thanks in advance for doing all of the heavy lifting and making my (web surfing) life easier.
xxgemini (author)  billb6 years ago
thanks bill, glad i could help.... those u.fl connectors are all over eBay, this one should do if its long enough for your application. http://tinyurl.com/5jxmre . yeah you want to buy it pre-made those small connectors are not fun to put together. hope that helps ~ Will
A good source for U.FL to RP-SMA pigtails:

Thanks for your super quick response. You've helped more than you could know. I'll have to get the camera out and make an instructable when I drill into the Mac Mini. Thanks again.

Who is the manufacturer of your amplifier?
Very neat how do those USB antenna's work? i understand there's power but how does it draw in signal? through the data side of the usb?
um the usb is for power
jeuno ellisgeek6 years ago
There are some usb devices that claim to extend the signal. I think that is what he is talking about. Not the particular amps power source.

more than a comment a question... how far does it really work, cuz my house is only like 400m from school and I wanted to know id I could use something like this... of course I would have to setup an aces point on the roof... would it work?
It would be interesting to see if this can be made using a mc type connector rather than the rp-sma type - I imagine it would be neater. The reason I mention it is because there are more mc to n type pigtails out there for connecting to the home made can-antenna I haven't made yet.... (I'm just doing my research at the moment :-) )

This is wonderful! I'm putting this dell 1390 card in my Acer Aspire One and wasn't sure what connectors and stuff I needed for the external antenna. Thank you so much!
edwardbuck6 years ago
Hello, I read this several months ago, but I have never been able to get this mod to work. I thought maybe I had a bad antenna or cable, so I purchased another of each, but still no luck. I have tried two different high gain antennas and two different U.FL to RP-SMA cables, but I don't get any better signal than with my builtin antenna. Any ideas on what I'm doing wrong? I have a Dell Vostro 1700 with Dell 1390 WLAN card. If I disconnect the high-gain antenna from the pigtail, I get no signal, so it appears that it is making connection, but if I get one bar with my internal antenna, I still only get one bar with the high-gain antenna. Thanks.
Great Instructable right down to the ferret! I have a dell XPS and am not sure where it could come out on the side. I'll have to crack open and look. Does anyone out there know where to get laptop internal diagrams? Once again great Instructable!
I know you posted awhile ago but I usually go to http://www.eserviceinfo.com for manuals/diagrams.. Give that a try it may help.
