Question about SENAO High Power 200mW USB WiFi 802.11bg Adaptor with External Antenna (655216003026) Wireless Adapter

1 Answer

Have been trying to install several different wifi external antennas - Engenius, Linksys, a "home-made" one. Problem with all of them is the same - the hardware is recognised, but the signal remains the same (or even weaker!) than my original wireless connection. Have downloaded all latest drivers i can find, to no avail. These antennas DO work ok on an XP laptop, it's my Vista machine which seems to be the problem. I have a Sony Vaio VGN-TX56SN/B, running vista biz. The XP (pro) laptop which does run the external antennas successfully is a similar, just slightly older vaio. On the XP machine, i get at least a 2 bar boost, on the vista machine, signal is same or less. Am on a tiny island in Langkawi (Malaysia) with few resources, spent far too many days on this now and about to pull hair out ! tks.... Diane

HG8245A VS HG8245: The same Wifi Signal Strength?

Probably not...... With an External Antenna, there is nothing to stop the signal, whereas with the Internal, the Signal has to penetrate the case, before it goes to wherever...... I suggest using the External for the extra distance.... With 2 way radio the clearer the area yo have the Antenna, the greater the distance.... same here.... just using different Frequencies.

On my ibm thinkpad 1120 i recently installed a wifi card and wifi antennas, i tucked the wifi antennas under the side of the screen and powered it on, it worked great, later on the screen start to act...

That's highly unlikely that the wifi antenna caused the problem.

It's probably the lcd itself or the lcd cable.

You can get the whole lcd complete on ebay for about $30. That's probably the best route to go, otherwise you'll waste hours troubleshooting.

First off, the EOC-3220 series comes in two choices: the ones ending in EXT, which require you to add an external antenna, and the ones without, to which there is no place to add an external antenna. So there is no decision to be made in the software configuration, because it's all handled above the software's pay grade.
Other Engenius models with "either/or" antennas come with a physical switch that allows you to choose between the internal antenna and the external jack. So again, there's no software contribution.

OK maybe get an external antenna in any event place the Unit/Antenna up as high as possible... also ensure ya aren't near any large metal objects/power wire junctions etc, but generally an external antenna will Boost ya signal, also even just moving "it" somewhere else can make a big improvement... In some wifi routers ya can increase and decrease ya output, ya may wanna check ya manual to see if yours is one of those? Ya may also want to try changing "Channels" on the Router too.. this also has been known to help. Good Luck :)

How to make my own wifi antenna splitter?


If you are planning to use a single antenna and then use a "splitter" to connect two (2) WiFi units, I'm afraid that it will not work.

Antenna splitters are meant for receive only mode but since WiFi operates both on receive and transmit, then perhaps what you would need is a "duplexer".

Both of your WiFis would be operating on 2.4GHz band.  Theoretically, you would have to fix set your first WiFi device to operate on the lowest channel possible and the other on the highest channel possible. The channel separation translates to frequency difference; lowest for Channel 1 is 2.401GHz while the highest for Channel 11 is 2.473GHz.

Constructing your own would be at best a daunting task since you would need to be very familiar with electronic components and circuitry in the microwave region. Further, you have to have access to specialized equipment (microwave capable) such as a spectrum analyzer, swr meter, dummy loaded wattmeter and a frequency counter to say the least.  In most countries, you would also need certain licenses to do this.

With all of these in mind, your best bet might be to use individual external antennas for each WiFi device and positioned them as far away as possible from each other.  Moreover, pls bear in mind that anything between the transmitter and the antenna would introduce attenuation, insertion and return loss and this include even just the cable.


If you would still want to give it a try:

  1. Here is a   link  to  commercial duplexer for  amateur radio;
  2. Here’s a   link  to  a do-it-yourself page for lower amateur frequencies;
  3. This is a   link   to a component supplier page.

Good luck and kind regards.
