I'm a recent mac convert(one week actually), and I've been trying to get a good usenet program that actually functions correctly. My problem is that whenever I try to download several large files from usenet, my internet gets disconnected. Actually, it crashes my entire network. I'm not able to reconnect for several minutes. I've tried three usenet applications(iGrabNews, Unison and NZBgrab) and the same thing happens with all of them. This does not happen on my other Windows PC with Newsbin Pro. Any ideas? Any help would be appreciated. The only thing that I can think of is that my internet is plugged into a wired router, with my wireless router branched off of that. My MBP connects to the wireless router, whereas my PC is directly connected to the wired router.
