Thanks guys!
I guess I will switch out the SMA connectors next. Did some reading on the forum but I don't actually get why not to use RP-SMA. I guess the older RP-SMA connectors where pigtails? In any case, I have RP-SMA connectors with identical form factor and will switch them out eventually, since I have more RP-SMA antennas then SMA.
@Yak Thats odd, I mainly use Chrome and never noticed any SSL errors. Is your internet connection IPv6 exclusive by any chance?
