So I upgraded to 1gig internet. The modem is plugged directly in the Time Capsule. On the 2nd floor, I have a AirPort Extreme being used to extend the wi-fi signal. The internet has been really slow lately, so I opened up utility and took this photo... So, from this diagram it is saying that the TC, that is connected directly to the modem, doesn’t have signal...but somehow the signal is being sent wirelessly to the AirPort Extreme...?? Not sure how this can even happen, the modem they installed is not wireless...so why is the TC showing no signal, while simultaneously sending a wireless signal to the Extreme?? Thanks in advance. Please keep answers basic, as I am pretty dumb with this stuff.
