Motorola WU830G USB Wifi extend range

markshmid · 06-26-2005

Hi, I have a Motorola Wu830G USB wifi adaptor. I wanted to extend the range, so I pop it open and there was an MC connector on the board. I got a 16 db antenna with the pigtail that I need.
But it does not work (extend the reception). Is the MC connector on the board disabled? what do I need to do to make it work?

Please help

That connector might be what engineers call a sniffer..In simple terms a test port connection but it is hard to tell without looking at the board..

You sure it was an MC?

You got an FCC ID # of that thing?

I will upload a picture with the connector, so you can see what it is

Please let me know if there is anything else you need to know

Was the MMCX connected to anything before? If not, can you identify the current antenna as an etched area on the PCB? (It would probably be on the opposite side ot that shown in your image.

A better picture would be a close up of both sides of the card, taken in the same plane as the PCB. A scanner sometimes works well for this, if you can't take macro shots with your camera.

In addition, are you sure that the signal isn't extended? You don't state if you're using a 16dB omni or directional. FYI: A 16dB omni would be a very flat pattern (~4-5º), and might be easy to miss.

It looks like there's a diversity switch just prior to the MMCX.

I did not change anything on the board, when i poped it open this is the way i found it.

I put the antenna right against a wireless router and the signal did not pick up. (I have a Conifer # qd2452 they are based out of AZ 480 315- 9283)

you can see a wire going from the MMCX on the left side to the bottom of the card were the card is cut (it says ANT1) on the board

also on the left side there is a round hole in the board next to that there is another circle and next to that there is a SQ. where it says (ANT2)

Where? and how do I turn it on?

here are the specs on the Antenna.

First, understand the diversity switch is a SWAG, based on looking at the traces. See the image below for what appears to be the DS. You may be able to ebable/disable it in the firmware. It may already be enabled.

Secondly, I wouldn't expect to see any increase in the signal (or very little) when the antenna is "right against a wireless router". I might possibley expect to see a damaged router however. Move the router some distance away, (like several rooms at a minimum) and try again.

Are you using proper tools to analyse the RSSI?

Finally, from you desciption of the board layout, I'm wondering if there is a integral antenna to the case? It sounds and looks like the "ANT2" circle is possibly a contact pad.

@ markshmid,

Can you get a macro shot of that thing from the connector down to the area Thorn has marked? I have a closeup of that area but the f-tard testers put a unit test id number over the goods.

If possible can you get a good macro shot of these areas?
