Old Airport Extreme vs. new Express to extend network
I have a newish Time Capsule that I bought in 2014. Lately, I've had some issues streaming to my Apple TV, which is located in my basement. (The Time Capsule is on the second floor.) I thought extending my network might help with the streaming issues. I extended the network with a 2nd generation Airport Extreme that I retired when I purchased the Time Capsule. I haven't noticed an improvement, and possibly the issue has gotten worse. So, would a new Express provide better coverage than the old Extreme? FYI, I'm extending wirelessly for now because I don't think I can easily run ethernet through my house. Thanks for any input.
