Time Capsule and Verizon Westell Wireless Setup Experience
This reply comes a few months after the thread stalled, but it googled high when I was trying to set up my new Time Capsule with my Verizon Westell Wireless DSL Router, so I thought I'd share my results.
First thing I did, under advisement from teh Apple Store Genius, was do my first TC backup for both my MBP and my wife's iMac by telling the AirPort Utility to connect the TC through Ethernet. This was suggested because the first backups would take a very long time over wireless. So I connected the two computers to two ethernet ports on the TC with two ethernet cables, plugged the TC into the power strip, and used AirPort Utility on each of the macs to connect to the Time Capsule. This I did to save time, but I could have done each computer separately if I had only one ethernet cable.
One glitch was that after the MacBook Pro was set up and starting its backup, and I then started to set up the iMac a few minutes later, the Airport Utility on the iMac reset the Time Capsule, stopping the backup on the MBP for a few minutes. It started up again, but that was unexpected.
Anyway, after only about 6 hours, both computers were backed up for the first time.
Then I used Airport Utility to add the TC to my existing network, since the Westell Router has the DSL uplink I need for internet. Time Machine started backing up, but it was really slow.
Then I tried using one of the ethernet cables to connect the TC to my Westell Wireless Router, and used AirPort Utility to add the TC to my existing network again. Within minutes, each of the computers were adding to the existing backups on the TC over the Westell wireless network, and speed was much better. I'm happy.
I do wonder, though, if it would be possible to use the TC as the wireless network, and the Westell as just a DSL modem, and if it would be faster. Right now the Westell is pretty fast, very reliable, and has good range in my house.
