The stuff I've read suggests I should let the TP Link act as the router, run in bridge with the Airport Express as an access point and take advantage of the AE simultaneous dual band and good conectivity with my Apple devices. I would run ethernet from TP-Link to my iMac.
My question is - is it an alternative option to let the Airport Exress act as the router and run the ethernet cable from the AE to my iMac?
If possible, what are the pros and cons of both.
(By the way, sorry about all the network questions lately - but I am following all the advice I am receiving, am very grateful for it, and am having great fun experimenting with the various setups.)
