Just got a new airport time capsule (2013 model). The time capsule is put in bridge mode and the modem/router from my ISP (thomson 585 v8) is doing the router stuff (dhcp, nat). Time capsule is connected to modem/router via ethernet cable (100mbit is the interface of the router).
The question is: if I put the modem/router to bridge mode (my isp's configuration gives the option to bridge the modem) and turn the routing stuff to time capsule will my network become faster? Does the 100mbit conncetion between tc and modem slow down things in the local network?
If you connect to the TC (via whatever speed you can get with wireless, or gigabit cable) then your communication to it and any other device on teh same LAN that is also connected to the local LAN is unaffected, it is only when you wish to send traffic over the 100mbit modem connection that you will be limited to it's speed, so basically your internet will be limited to 100mbit, and so long as that is faster than your ADSL/Cable connection anyway, then you will never notice it.
