I have an old Linksys WRT54GP2 wireless router and want to change the antenna. Does it use a R-TNC or R-SMA connector? I suspect it's the former but notice some Linksys wireless routers do use R-SMA instead of R-TNC.
"One thing to note is that this router is a little different than the WRT54G without the phone ports. This router has only one antenna. This also means that if you would like to replace the antenna with the Linksys high gain antenna you will need the SMA antenna and not the TNC antenna. I learned this the hard way after Linksys sales told me to use the TNC, which was just wrong."
Found this after posting so I'm now leaning to R-SMA but if someone can confirm this I'd appreciate it.
