I have always been frustrated with the performance of my notebook Wi-Fi. I tried many solutions to improve the signal from far away routers, but a number of these worked. I’ll insure an answer that I came up with this finally did return some results for me. Most notebooks today have a mini PCI Wi-Fi card hooked to an antenna which is located inside a screen plastic cover on the notebook. I was browsing eBay lately and noticed there were some Wi-Fi amplifiers accessible that encouraged themselves as enhancing the reception of this signal. Regrettably most of those amplifiers have been designed to be hooked to a PCMCIA type card or even a router! None of them seemed to be especially made for a mini PCI card. I’ve got an ASUS A2H notebook using a Dell 1470 a/b/g Wi-Fi mini PCI card inside, I purchased the card for $20 off of eBay. I purchased the amplifier for $118, it’s a 500 mw bi-directional amplifier known as "turbo tenna", the amplifier was sent from Hong Kong and I received it soon after ordering eBay. The first difficulty I faced with my card would be the connectors, they are so small and rather tough to connect to a plug, purchasing a special connector for the card could have cost me another $15 plus shipping, so I chose to solder the cable straight to the card. One of the best characteristics of this Dell 1470 is you can select the antenna plug you would like to use — aux, so that I picked the primary and that I soldered the cable to it. The second difficulty was electricity supply! As usual, in case you have a mother board the very best power supply you can get is by a USB port. I had 6v, and the USB was giving me 5v — near enough! The next difficulty was hooking the card to the amplifier. I had 2 choices, I could either take off the circuit of the toaster and discover a place for this in the notebook, and it is a wonderful idea, or I can get a way to hook it externally. Though I wanted to put the amplifier in the notebook, I chose to not do this for the following reasons: I desired more freedom hooking any antenna I wanted to the amplifier. It is very difficult to discover a spot for the amplifier inside the notebook without affecting other components. Heating issues! Those amplifiers produce heat and they aren’t provided with an adequate heat dispenser. The amplifier was expensive ($118) and that I wanted to conserve it. I chose to hook the amplifier through the VGA monitor out port! Why? First reason, the vent is strong and will hold the weight of this amplifier, also it comes with screw holes. The VGA plug and Wi-Fi antenna cable (see large image) Second, the VGA interface comes with a couple pins that are unassigned, occasionally they are soldered to the floor, and in some cases they are simply soldered to nothing. Therefore it was a matter of testing those particular pins to find out if they were attached to anything else about your mother board. After assessing the pins I found out that hooks # 9 and #11 were free, so I used #9 for its electricity supply and #11 for the antenna cable in the Wi-Fi card. I used the floor for the VGA for as a common ground for the power and antenna cable. 1 thing that I should mention, I am a switch nut, the more knobs on the device that the happier I am. I placed a switch inside the notebook that switches all of the wirings involving "regular " and "amplifier on". I have attempted many Wi-Fi antennas, the "spider" antenna is powerful but doesn’t provide high gain, while the so called "russian" antenna provides you more gain, but it’s a bit bulky. I have used the russian design antenna within this experiment. Spider and Russian antenna examples (see large image) Amplifier hooked to the notebook (see large image) Using "Network stumbler" as a testing software, here are the comparsions between amplifier and normal on: The signal is feeble and intermittent, so it doesn’t even reach -90 dBm, which is very weak. When I get lucky, the relationship is generally 1Mbps with signal strength 0-1% and at times no connectivity (I suppose you understand my frustration). Not many signals are found, and sometimes nothing at all. Amplifier ON: A dramatic rise in signal strength! More than -80dBm, and the speed of this relationship is 24Mbps with signal strength 34 percent as compared to the same connection at 1 percent previously analyzed. You can also view more Wi-Fi connections about you, though of course they’re all password protected. You are never disconnected wherever you go! Very mobile and removable modification. Radiation, I feel this thing produces the same amount of radiation a cell phone produces, therefore try not to keep it too https://abcdereviews.com/wifiblast much, especially once you don’t want it. Power consumption! It drains your notebook battery. Interferes with the back of the display, unless the VGA interface is on the side. Requires an inner modification to be used on the VGA port, the VGA port might cause probems if hooked to a monitor that uses the unassigned hooks (very small likelyhood, however, the switch I created saves the situation). . .and guts. Every nation has regulations, be careful to not break the rules when hooking such a strong thing to a card. Amplifier provider says: "Don’t exceed 50 mW to the input of the pencil booster", therefore if your card gets greater capacity then it might hurt the amplifier!
