Linksys (Cisco) e2500 or n600 external antenna mod

stripping the wireantenna cable after stripping.


Strip the new antenna cable to prepare for soldering, I used an electrician scissors stripping tool.  It worked pretty good, but the cable is tiny!

Prepare for solder

6.)   SOLDER!







final soldered antenna cable

Here is the final solder job,  not pretty..but works.   I tested the solder job with an ohm-meter, by placing the leads between solder points and making sure they were not conducting, then placing them on the other ends of the pigtails making sure I had conductivity.


Solder the other 2.4Ghz cable the same way.



Disconnect the 5Ghz (black) cables from the board, and replace them with the new cables that lead to you new pigtails and antennas.   As you can see, I drilled holes in the top of the router to house the other set of antennas.

Crank it up and let ‘er rip.   I replaced the dlink with this Linksys and tested my signal strength.   Even though I do not have qualitative data on the increased signal strenghth, I can tell you I get excellent signal strength anywhere in the house, and even into the neighborhood.  I am very happy with the end product!

I really hope this helps you out on your quest to get a better WiFi signal!

    You could just cut the original antenna wire, and the new one and splice them together to save yourself a soldering job, and to make sure it’s soldered perfectly.

      Not a good idea actually a bad idea because you will ruin any chance of the outer shield braiding to do its job and so introduce much noise and signal drop to poorer than poor. Try it, and you can see. Whirling very important. Cutting corners not good.

    How hard is it to solder for a first timer or splice wires ? I’m considering doing this instead of buying an asus rt ac68u with wifi extenders, etc the works (expensive lol) but just upgraded to 150mbps ‘blast!’ Upgrade from Comcast but 8t hasn’t helped much…. also, what do you guys think about a yagi wifi 15dbi atenna? Is it even possible to use one.with the.linksys n60p? (Off topic but – can you believe 505mbps is their fastest wifi package but it costs 499.99 use a MONTH, and yes its a home service not business lol. Who has that much money man… it sucks 150mbps or 505 nothing inbetween. Most routers can transmit far more yet the ips don’t provide those speeds at all; let alone for a reasonable price.)

    I am doing this same mod but for the 2.4GHz portion I am using the empty pads to solder in two U.fl coax connectors to match the 5GHz connectors. That way I don’t have to worry about botched solder jobs like what commonly happens soldering the coax directly to the PCB.

    Hey this quide is great any chance we could see any higher resolution images, Im curious about the 4 wires and where they got soldered to….Thanks

    I ordered the antennas and today when I had some time unplugged my router and opened it up. It’s a E2500 but it only has two antennas. One grey and one black. Since I had the antennas and the router open I went ahead and installed one of each but wondering why I have single antennas and yours has dual ??

    Was just about to make this mod, then realized my router is a bit different. It is a E2500 version 2. It has two antennas connected by cables like your setup, the other two seem to be soldered to the board directly. However I am not sure of this. Was wondering if you could help me out figuring out how to mod this version?
