External antenna

Postby cwrx777 » Thu Sep 27, 2012 5:15 am

Any guys want to mod this device to use an external antenna?
We can use this connector

near the USB host connector.

The ug802 is pretty much setup for the u.fl connecter. The pads are in the proper placement too.

I'm going to stick with just soldering the cables for now. It's a bit easier for the average person.

I've actually just finished doing this with a small rp-sma connector I pulled off an old wifi dongle.

It's simple to de-solder the internal antenna then solder a couple of wires to connect the rp-sma connector to the pads. The hard part is figuring out where to put said connector and how to attach it.

The connector is held on by the pressure from the antenna and 2 small washer rings against the plastic shell.

Preliminary testing results seem to be much better than the internal antenna and I have yet to experience wifi drop issues, but we will see once I get more testing done.

Be very careful when soldering your wifi. Thos pads are not strong enough to take much pulling.

I actually just completed the wireless mod also. I've taken an old linksys rp-sma connecter/antenna and connected it to the stock antenna wire.
I had it soldered to the pads, but as I was putting the ug802 back together one of the pads and trace pulled out and off the pcb!
It was probably due to the thick wire I was using.

I resoldered the stock antenna wire to where the wifi board meets the pcb. I burned a small hole in the side of my case for the wire to exit. I cut the stock antenna off the end and stripped the wire. I then soldered onto my rp-sma pigtail.

I currently have the pigtail held onto the case with 2 pieces of electrical tape as a strain relief.

The result is I can pick up the wifi in the next house over with full bars. I can also barely get the wifi from two houses over.
I've had no drop outs or disconnects after doing this mod on a troubled wifi UG802.

Hello, can you share some photos of your modification ?? I'm good with electronics and I want to do some modding to my ug802 and also this weekend if I have time I will make custom case for ug802 which can have room for usb ethernet card, 4 port usb hub and the ug802 itself..

wish me luck D:

I actually had the same worry that the trace could possibly be damage due to strain, so I used 26 awg solid wire and wrapped it around the pub lengthwise like how the stock antenna wiring was routed.

Unfortunately I've had one dropped connection while streaming Netflix last night after about 40 minutes during my 2 hour test, which leads me to believe the wifi chip may be overheating or maybe my wires are since I ran them directly over the rk3066 chip.

I'll move the wiring away from components that generate heat and see if that helps for my next test.

I pretty much just took apart my ug802 and desoldered the stock antenna.

I then soldered on the big antenna (white wire)

At this point as I was putting the case back on I put too much stress on the signal solder pad and it pulled right out taking the trace with it.
So I soldered the stock antenna wire to the backup points, and soldered the big antenna wire to the stock.
I didn't take any pics at the time because I was now in a rush.

I also burned a quick hole in the side of the case so I could access the reset pads with a screwdriver.

Is it possible to use the "Backup Solder" points to add a second antenna? Or are both sets of point tied together?

Both points are tied together. I only used the backup points because I destroyed the other points.

I just got my UG802 and big surprise, no wifi signal from my wifi router upstairs :(

I am thinking that I should use one of these

with one of these

to make the reception a little bit better.

What ya all think?

Mu unit has the small antenna pad not the big one like the most of the units have

you can get 3 pack 9dbi antennas on Amazon for ~ten bucks.
Wonder if anyone tried those?
There are 2 varieties - one with stand and extra cable and simple screw on. Antennas almost 1 m (3ft) long.

There is also a WiFi-to-Ethernet adapter with USB powering. Coupled with Ethernet-2-USB can be a solution for some people. In that area is also using spare router in extender mode with wiring Ethernet to UG802. Or spare netbook with software router and again wiring it to UG802.
