Hey guys... I bought a Netgear JNR1010 and a Netgear WGR614v6. I have a couple of 10DBi antennas and I wanted to attach them to the routers. However I am having a huge problem.

The router transmits a better signal without the antennas, than with them;which is quite weird...

I am guessing my soldering is not right... so please can you clarify some things:

The RP-SMA to U.fl contains 1 wire with a metal sheath-like thing where:

A) the core is the wire with a smaller metal wire in it,right?? and you have to cut of its sheath and connect that metal part to the jack, right??

B) the metal sheath-like thing, around the core wire is the grounding wire, right?

I have attached some photos of the antenna jacks.
Could you guys please help me get the right wire in the right area? Thanks guys...



P.S.: Just removed the drawings

Is your drawing for the wgr614? Can you make 1 more for the other? Thanks

Here are the best pics I could get of my router antenna....

Pls use paint to show which part of wire connects to wherever....

This is my WGR614v6 Antenna jack

I have 3 jacks on my JNR1010


yea the soldering sucks cause both are old and I have soldered/de-soldered the same spot for long periods of time and I guess the router took some damage... =/

no i wouldnt connect anything to it at all, it looks like it is running off the same antenna line as antenna 1 anyway, and is missing c68 capacitor required for it to work. it is probably just on the board for a model that uses an internal antenna and no externals. cheaper for them to make the same board for both models and just modify the case / add internal antenna

you could use the capacitor from ant3 of the jnr and put it on your wgr to replace one of the missing ones, but you would still need another. you could also just bridge the pads but it might effect signal quality.

I soldered the antennas as you have instructed me to, but Im just not getting any range whatsoever... Is there any way to determine if the signal is passing through the antennas??

which router are you talking about? youre missing capacitors on the one as it is.

take a good picture of your soldering job and post it so i can look at it. zoom it out a little so i can see the trace all the way back to the wlan amp. you may have broken off another smd cap or resistor somewhere.

Well the WGR614 worked with its previous antenna without the capacitors... Cause I dont remember seeing it there when I bought it.

The photos suck but the PCB is messed up...

i really cant tell from those pictures, the light level is making everything look the same.

the inner core wire cannot be touching the outer core wire at any point. that is why the inner core has a shielding around it

ant2 almost looks like you have soldered it on backwards from the way i drew it

the wgr is soldered to the wrong spot, i dont know if maybe you broke off the solder pad where it was supposed to go. unless you can take an ohm meter and get a 0 ohm reading across the pads where the capacitors should go, there should be capacitors there. if you get an open reading, then the trace does not connect the two pads and your signal will not go across either. all antennas i have seen have a capacitor there.

Now in the JNR1010, the antenna pad is has a flat base where I joined the ground wire. I didnt join it to the to side panels. Will the ohm meter tell me if the signal is passing through the antenna??
