Boost wifi signal...be a tinker

by Willy / September 15, 2008 10:37 PM PDT

"My name is Bond, James Bond". Just when you though it was safe to wifi, comes someone who wants to save or get better reception.


These antenna have been around for a long time, so its nothing new. Its just that applied to current wifi setups, I was surprised the ease they could be done and many have already. Use keywords, wifi boost, Yagi, or USB antenna for hits. enjoy -----Willy Happy

The only problem I might foresee is this... The fellas doing this were hooking up to a pcmcia card. It obviously had a connection where you could add an external antenna. Most recent wifi router manufacturers have begun making their products permanently affixed antennas. In other words you can't take the old antenna off to replace or attach a new and improved version.

Sigh... I guess the manufacturers discovered that it was more profitable for them if they could force the consumer into buying a new wireless router when the antenna got broke. This is just one of many ways they make the consumer buy a new product rather than fix or maintain an old one. I noticed years ago that cheaper appliances and electronics came with glued together cases on things like DVD players and cheap VCRs.

Another thing that is not user upgradeable ? The cheaper shoes you buy at stores like Payless Shoes store. A cheaper pair of black Rebock tennis shoes comes with the insoles glued into the shoe. Considering the insoles wear out long before the tread does on these shoes, you are forced to replace the whole shoe, rather than pull the old insole out and upgrade it with fresh ones.

looking at the photo example...

In reply to: I tried this model

if you glue the foil to the template and then put the device onto your antenna... then most of your antenna will be on the wrong side of the tin foil. Will it not ?

ANTENNA ---> foil | cardboard ---> direction of desired enhancement

The only part of the antenna on thee reflective side of the foil is going to be the tip ? It looks like it might work if one were to attach the foil to the acetate... the acetate to a layer of cardboard... and sandwich the antenna between the two layers.

Worth a try ?

In reply to: Response

I knew a fellow years ago, who was given a c band satellite dish (the big 10 foot ones) from his neighbor who said the thing never worked correctly. This guy I knew was a real jack of all trades who had a fundamental grasp of science but was mostly self taught past high school. He got a measuring tape and some string out, and did some figuring after measuring the dish and discovered that the curve of the dish was reflecting the signal to a point about a foot past the LNB that picked up the signal. He rigged up a new boom to extend the LNB... and had a perfectly good c band satellite dish.

I have to wonder if there is a somewhat similar issue with creating a reflector such as this one. Could it be that there is such a limited sweet spot where the enhanced signal boost works that such a device is impractical for most real world situations ?

Known for years as the "State Flower"

The ridges are so steep and close together in most parts of the state that TV reception by antenna is often impossible unless you lived on top of the ridge. Cable companies were few, and rarely willing to run line out to a customer who lived out in the boonies. As soon as the dishes became affordable (still a couple of grand in 1970's currency) you saw them sprout up all over the state.

Many methods abound

I used the foil method myself just to see if it'll work. It does. However, you crinkle the foil too much you diffuse the signal. So, in that vein you can really crinkle the heck out of it and then use. -OR- use silver spray paint instead, paint the cardstock.

I found one very simple. So simple it has one part, a "mesh strainer". Get a 8in. strainer, fine mesh used for cooking. On the bottom, make a hole to route the USB antenna through. Then mount it to the base the use USB antenna has, Belkin model. Then plug-in and find best signal. It was the darnest thing, it worked all for $2.00 excluding Belkin USB antenna. -----Willy Happy

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
