I am seeking a product that I do not know if it exists or not. At present I am using a Linksys WRT610N. It does have wifi, but no external antenna jack. I also use a 1,000mw Ubiquiti Pico Station wireless wifi access point. I want to find a router that has high power, such as the 1,000mw FCC maximum AND an external antenna jack. My main computer is below ground level and if I used it's wifi the signal is substantially attenuated.
Hopefully one of you Experts knows of such a product. If that fails I think I will take the Linksys modem apart and install an antenna jack in place of the internal antenna.
