Last week I bought a new Airport 2TB Time Capsule and had everything up and running within minutes. However, less than 24 hours later, the wifi signal started dropping devices all around the house. It started with the AppleTV, and eventually dropped our iPhones and iPad as well. The problem is one I've seen on these forums before (however, not with this new model).
I since exchanged it, and the new model is having the identical issues.
Basically, the problem is 1 of 3 things:
1. You'll look down at your iPhone (or whatever device that is wirelessly connected), and see a full wifi signal. However, you'll have lost access to the Internet. Using the AirPort app won't find the Airport Time Capsule. Sometimes turning off wifi on the iPhone and turning it back on fixes the issue, sometimes the Airport Time Capsule needs to be restarted.
2. The AirPort Time Capsule stops broadcasting SSID at random intervals. Even when standing right next to it, there is no way to join the network.
3. The Internet connection drops in the middle of a browsing session (usually while using an iPhone).
On both devices (the original new one, and the replacement exchange), I immediately ran the firmware update. So, I'm thinking this could be a firmware issue.
This router replaces a Linksys e3000 that was working flawlessly. It's connected to a Cox Cable Cisco DOCSIS 3.0 modem (modem only, no router). The AirPort Time Capsule runs in WPA2 protected mode. It's running DHCP and NAT, and 2.4 and 5ghz are currently running the same network name (although I've tried separating them to no effect).
I am at my wits end. I find it hard to believe that both of these routers are defective. And I also find it hard to believe that I'm doing something wrong in the setup of this simple device, considering I've been working with all kinds of very complicated routers for over a decade without this kind of problem.
So I come to you, community, for help!
Thank you in advance!
