How can I determine the speed at which my AE is communicating with my AEBS? I have the AE set to "join network". I know I can get this info easily for my MBP but I have not figured out how to do it for my AE. I see the AE in the Airport Utility but do not see any info on transmission rate just "connection: excellent". I am looking to get a powerline adapter for the AE and would like to be able to compare transmission speed between the AE and AEBS before and after using the adapter. Also, with a powerline adapter, is there any advantage/disadvantage to using the AE to extend the network vs join the network. Right now I am getting between 70 and 100Mbps on my MBP. Would be nice but not necessary to boost that even higher if there are no serious tradeoffs. Right now, my understanding is that if I set the AE to extend the network, my transmission speeds will actually decrease because of the increased communication between the AE and AEBS. I think I tried that a while ago and that is what happened. So I went back to just joining the network. Have to admit, I get a little lost on network stuff, so thanks for your help.
