I'm having a weird problem with my wireless network/Time Capsule.

Randomly, after connecting and then disconnecting to the network with my work laptop (Macbook), the other wireless clients (wife's iMac, airport express) can no longer see the wireless network. I can't access the Time Capsule via Airport utility even through the my ethernet connected iMac in my home office (although my ethernet connected iMac still can access the internet).

I figure it's a problem assigning IP address assigning issue, but I can't figure it out since I can't access the Time Capsule through Airport Utility, even though Airport Utility shows a green light in the left pane of available wireless devices.

The only way I can fix this is to reboot the Time Capsule. Rebooting the wireless clients (wife's iMac and Airport Express) do not fix the issue.

I have the latest Time Capsule firmware.

Any thoughts?

 

Quite possibly an IP conflict if both the time capsule and another base station are handing out IPs on the same network range. It would be best to use a static IP outside of whatever dynamic range you're allocating, but on the same network, for the time capsule.

You'll have to check the network configurations for everything involved to be sure.
