How does the current generation Time Capsule / Airport Extreme compare to the competition when it comes to WiFi coverage these days? There are a lot of highly regarded WiFi routers from Netgear and Asus out there. And there are anecdotal reports that they cover better than the Apple gear. I ask because I have a customer. They have an older Time Capsule and an AirPort Express that tries to extend the signal wirelessly, but it still doesn't get the job done. (Yes, I know it would be best to run Ethernet between the two, but trust me, there is no cost-effective way to do that where they live). They live in a 20 story condo building. OK, without getting too deep into their situation... Does the competition do a better job at WiFi than Apple?
