Hello everybody. After reading and following several suggestions posted on the forum, the problem of dropping internet still occurs. Here are the details:

Two machines: OSX 10.4.5 and Windows XP
Wifi router: Netgear WGT624 w/latest firmware rev.
Cable modem: RCA

I used to think that the problem lied with the modem. The first few times the connections would drop, the Apple AirTunes stayed connected and streaming from iTunes to my stereo. Lately, however, even the WiFi connection dies out; the connections drop and if I disable/re-enable the AirPort card, my WFID doesn't appear.

In the Netgear settings, UPnP is on; Advertising period is 30 minutes; Advertisement Time to Live is 4 hops.

I tried bypassing UPnP and doing a classic port-forward, rebooted the router, connections still drop.

When this happens, I notice this line appearing in the cable modem event logs: SYNC Timing Synchronization failure - Loss of Sync (date Jan 1 1970 - when modem cannot connect to Sync time server).

To state the obvious, my connections drop only when Limewire is downloading a large-ish file (more than 200mb). It happens regardless if i'm running it on my Apple or Windows machine.

I appreciate any input.
