So I just picked up a 3500L and was looking into adding external antennas. I found the old thread with an ebay link selling a kit. I emailed the seller and he told me the connectors on the pc board is not the same and the u.fl pig tail will not work.

So what type is it? it looks slightly taller and bigger in diameter than the Linksys WRT320N that I also opened.

Thanks

We received a message on Twitter stating that these are U.FL connectors, more info here:

Not sure if this is correct, but should be helpful info regardless!

thanks for the quick reply. I already saw that thread as well as the one on myopenrouter.com. I actually tried physically installing the u.fl pig tail from a Linksys router onto the on-board connector pictured, it didn't seem to fit. Then again, I didn't press very hard. I'll try again later today.

Thanks

I found this info on the net:

"Hirose U.FL connectors are protected by patents[2] and trademarks. However, compatible connectors are on the market under names such as IPEX, IPAX, IPX.[3], MHF, and AMC.[4] connectors."

cool. thanks. I asked a co-worker and he said it's probably a mini-SMP connector. I will measure the ID and OD when I get home to verify.

nice, I'm interested in the results, I jut got my 3500L yesterday and probably will upgrade the antenas too. When you buy the conectors please let me know.

one more datasheet for consultation about different U.FL conectors: http://www.hirose.co.jp/cataloge_hp/e32119372.pdf

I have to take another look but it doesn't look like a u.fl. I'm considering just soldering a bare pigtail to it.

from the picture, the connector on the wnr3500l board looks like the solder points are on the corners where the u.fl spec states the solder points are on the side.

it might be easier going the soldering route.

They are NOT u.fl. I purchased the antenna kits from ebay and they do not fit. I had to solder the bare pigtail to the board.

thanks for the pics! That's what I plan on doing. the only question left is antenna. I found some antennas on ebay and they only list "b/g" in description. I emailed the seller asking if these will work with "N".

Thank you for the pictures. Does it matter which wire you solder to the contact point on the board and the connector?

I'm still waiting for my kit, but isn't one of the wires connected to the center pin, and the other to the outer part that the antenna screws on to?

Some closer pictures to get the question going:

Any Ideas? I don't want to solder either, just use the supplied connectors, thanks all..

well, as far as I can tell no one seems to know what type of contact the connector is. My co-worker thought it was a mini-smp, but I can't seem to find anyone that sells a pre-wired pig-tail.

Anyway, I'm gonna solder the wires like the picture. I believe what you're seeing is the co-axial shield soldered to the outside of the connector. the actual conductor is soldered to the a point somewhere along the circuit.

this might help. I posted the same question on ddwrt and was directed to this thread.

May I ask what kit you bought? I can find any antenna greater than 9db that has wireless n listed in the description.

Thanks

Here is the antenna kit I bought. They are 7db antennas and the router they are for is a Wireless N Netgear. I'm not trying to boost the signal too much so I don't think I'll need anything more powerful that these. http://cgi.ebay.com/110526781284

The shielding is soldered to the outside of the connector and the center conductor is pushed through the pin hole next to the connector and soldered on the other side of the board.

These are Murata MM8430-2610 connectors.

If that's the case here is a catalog with some specs on the connector: http://www.murata.com/catalog/o30e8.pdf


Scroll down to pages 11-16.  Sadly I'm having trouble finding information about the male version of the connector.  Anyone have any ideas?

The Murata MM8430-2610 mates to MXGS83RK3000 or MXGS83RJ3000. The MM8430-2610 are designed for making measurements and not as antenna connectors.

Thanks!!!

Personally, I don't think it's worth the time nor the effort to try find a cable or pigtail for this. Soldering seems like the best route. Get some SMA with bare leads and you're good to go.

Hi Community!

Yeah, that's the way I went, too. I ordered three U.FL to R-SMA adapters, just to find out, that the U.FL cables were really hard to push on those connectors (but I really managed that by pushing hard enough ;) but later on, I came to the conclusion, that the inner wire doesn't make contact to the board at all, and thus the connector must be wrong.

So I took my pliers and carefully removed the three connectors from the board, (so I have easier access to the soldering spots), and soldered these wires to the board like VoodooDaddy. Now, having attached three 5dbi-omnidirectionial antennas, signal really is better, but not too much.

I am using the latest tomato-firmware with the router and I think that fiddling with the mW-parameter virtually does nothing  to the wifi-range, can anybody copy this?

Greets,

don
