Airport Time Capsule Problems Since Snow Leopard - Loses Connections

Question

I did a straightforward install of Snow Leopard on the iMac 24 and it went fine. I have very few apps on it so nothing weird running to cause two issues:
1 - Time Machine backups to a Time Capsule have become slow and unreliable. Also, even 10-100 MB file transfers to a MacBook Pro 17", also on Snow Leopard, took the longest time.
2 - The Airport/WiFi icon will often go from being a static icon with full signal to one in which each curved concentric level bar flashes one by one up from the bottom dot to the topmost arc, and then back down, and back and forth. This often happens in the middle of Time Capsule backups. Holding down the mouse on the icon shows my network still connected, but the backup fails, and any web page attempted will also report there is no network.
I wonder if others have had similar problem(s).

Answer 1

I am also having very strange problems with 10.6.1 and TC. The network disconnects for no apparent reason, frequently. It seems to be tying up both of the phone lines too, because once the TC reconnects to the network, the telephone no longer works (it says "line busy" and remains that way until and unless I unplug the TC). Plugging directly into the cable modem works fine, no problems at all with the telephones or with the network disconnecting at random. All three macs on my home network (macbook, MBPro and iMac) are updated to 10.6.1. At first I thought the problem might have been the modem itself but it works fine; it's only when the TC is connected that the weirdness happens.
