Currently using an Airport Extreme Gen 2. Am cutting the cord for cable and looking at all pieces to see if I should replace them. I am currently running one MBP, iPad and iPhone in a small apartment so do not have reception issues. Do not want to overpay but price is not so much an issue. Previous to using the Airport had had connection issues with a D Link router. Switched to Apple on the assumption (correctly or incorrectly) that Apple products play together better. I have noticed that my MBP connects to the wireless much faster at home than another MBP does at my office to a non Apple Router. I have added multiple external hard disks through a splitter with the current USB port and speeds are painful and as well as discovery of the disks spotty. What I am looking to gain from a new router: Ability to have a guest network. Faster saving to and retrieving from a hard disk,either external or internal with a time capsule. External is appealing as a 5 tb disk is relatively cheap with USB 3.0 or other types of connections. Faster wifi unless what is supported with the current router is as good as it gets. All comments are welcomed.
