Turn your standard WIFI antenna into one just like the $30 range extender antennas for about 5 cents! Follow these easy steps, and then check out the video if you need extra clarification. Digg if you like my very first Instructable.

Step 1: Remove the top of your stock WIFI antenna.

A small flat jeweler's screwdriver works great!
I'm totally ignorant about wifi (my caveat/confession): is the length of the antenna why my wifi connection keeps dropping in and out? I get it thru my cable company and it drives me crazy, especially when it drops out right in the middle of an instructable! It comes in thru our own router, and ever since getting the our own router is when the dropouts started. If amplifying the antenna will do the job, I'm all over it! Thanks for your help.
<p>Yes, I know this post is 6 years old.....but, it depends on several factors. First, are there any splitters or couplers in the service line either outside before entering the house, or inside before cable connects to the modem. Check behind wall plates too. This is common source of bad signal, especially if connections are corroded, or limit frequency throughput.</p><p>2nd, make sure all connections are tight. oh, and if you found any splitters, make sure they don't cut off too low. 5Hz to 3GHz is ok, but get rid of the ones than only go to 900Hz. Also helpful when troubleshooting poor HDTV signal. Also helps if the Coax used on incoming line is 3G rated. It will usually say right on the outside of cable.</p><p>3rd either your router is faulty, or configured incorrectly.</p>
probably not, it's likely your router. Even if you get your wifi router from your company you can still connect a second wifi router and use that. I would recommend a WRT45GL by linksys with the tomato firmware installed. I have one and it works perfectly.
i place all my time and faith in a belkin wireless router. it is very well worth it. you dont need the all new one because older ones work perfectly. and you also dont need any software to be put on it to make it faster. although you can if you want to.
You were right: I called the nice people at Belkin (manufacturers of my router) and they talked me thru a re-conformation/reworking of my router and now, it works great! I don't know if we set it up wrong or what, but it hasn't dropped out even once since doing it. To be perfectly honest, I have NO IDEA what I did, but whatever it was, it fit the bill!
I have a Q:<br><br>I have an old CB antennae that has been sitting around for like forever...would that work?? *evil grin*<br><br>I know that I would have to build a base for it &amp; all that, but if it'll work to REALLY pull in the net or whatever, then it will have some purpose.....otherwise its trash<br>
You would have to make sure the length of the antenna is correct for the resonant frequency (or part thereof). Most mobile type CB antennas range from 2-8.5 feet in length, which is the proper length for 1/4 to full wave resonance on the 11 meter 26.000 to 28.000 MHz CB band. As wifi broadcasts on 2.4 GHz the resonant length would be quite a bit shorter.
I did this hack, but it did not improve my signal at all. While I believe I applied each step correctly, I will detail the process below in case anyone can spot a problem. My only request is that you not post comments based on empty guesses when you haven't tried this hack yourself. EG &quot;Are you certain you used the correct COLOR screw&quot;? Thanks.. <br> <br>In the spirit of the hack, I used what was around my house. I had a roll of 20 gauge copper wire (bare), so that is what I used. After cutting the proper length, I used a 2 inch coarse thread drywall screw without any problem. I am crappy at soldering, so I used butt connectors designed for 18-22 gauge wire (red). I tested to be certain the antenna-to-wire connection was firm. Slipped on the straw cover and screwed antenna into router. Restarted router and refreshed wireless networks. Nothing, nada, zip. Still the same two bars I had before the hack. Because I had the same signal, I believe there is no break in the hack wiring or problem at the splice, or the signal should be worse. <br> <br>Did I miss something? Anyone else had this problem and solved it? Has anyone tried adding the extra 14 loops, and did that work? Other helpful suggestions? <br> <br>Beth
<p>yes, you missed the soldering. You can't use butt connector. come on now silly. How are you testing your signal after making the antennas? and papapaleeeze don't say the number of bars on your phone, or laptop, or tablet....or cat/dog.</p>
<p>What About for a laptop?</p>
<p>WiFi adapters built into laptops are different. Unless you buy an external wireless adapter, 99.9% of all modern laptops have wifi adapters that come in the form of tiny (approximately) 1 inch x 1 inch circuit board that attaches to the motherboard of the laptop via a set of small gauge wires. There are used for data being relayed between the motherboard and the wifi adapter, Data is processed locally on the laptop and then hands the data to the adapter, which then encapsulates it in the form of packets that will be sent through the air through radio waves. </p><p>You'll notice that your computer does not have a visible antenna. This is because the antenna is built into edges of the plastic casing around your computer screen. Unless you know what you are looking for, it just looks like an ordinary set of wires. The only way that this method shown in the instructable will work is if you have a USB wireless adapter with a visible antenna. I say &quot;visible&quot; because a majority of adapters do not have an antenna sticking out of it. In my experience, most wifi adapters that I have worked with that have an antenna are the ones that advertise high gain, which is a not-so-fancy way of saying that it can transmit and receive at a greater distance than their flash drive sized counterparts. If you have bad reception everywhere you go, I would recommend finding out if there is any warranty and contacting the company, since that would indicate a faulty internal wireless adapter. If your connectivity is good in some areas and bad at others, you might want to try a external wifi (and also disable the internal adapter in the laptop). Regardless, always check with the manufacturer first.</p><p>If you computer is relatively new, I would recommend not opening to see for yourself as this will almost always result in you forfeiting any manufacturer warranty remaining on the computer. I need to add this part, since this site is all about making, repairing, tinkering, etc. I am an IT tech, so I know my way around computer components, but regardless, I do not open up computers that I think may have a faulty component and are still under warranty. This is because a manufacturer is not going to care how much you know about computers. As soon you open a computer, they will no longer support the product you purchased, even if it is a faulty component that just died and would normally be replaced by a manufacturer under &quot;normal&quot; circumstances. Not all companies are like this, but it is better to consult the company that manufactures your computer before open it up.</p>
<p>Nope. built in wifi cards on laptops still use antennas that connect to the wifi card using same type of cable, but smaller, and is terminated with mini PCI connector. You can use an adapter cable like this one. small end snaps on to internal wifi card, and big end is where you screw your antenna on.</p>

<p>I used some heat shrink tube, triple thick at the bottom for rigidity and triple at the top and pinched it closed for a &quot;pro&quot; look. </p>

<p>Pinch the end of the straw closed with a pair of forceps, then seal by melting the closed end with a flame. Weatherproof and dustproof.</p>
