First time using the forum. I'm interested in tech, but I wouldn't say I'm tech savvy. I have a 4th gen TC with output speed whether wifi or ethernet is 50-94 down and 9-12 up. I have comcast 250 via cable and I get about 230 down and 11-13 up from my ArrisSB6141 if I wire it to my iMac with wifi not changing. Is this normal or should I be getting closer to the 230 down? I'm a foot away from my TC.
