Orion, here's what I've done: the router has been removed entirely. I've put the Local Area Network settings back to finding an Internet-protocol address automatically. With this excellent desktop computing system you built and gave me, I'll only be using the laptop occasionally. Although the "hardware firewall" aspect of a router is nice, connectivity is even nicer!

Under this new regimen, which is actually the old regimen, Soulseek works just fine: green lights all down the track. Yay! I've not tried either BitTorrent or µTorrent yet, but I'll do that today/tonight. What prompted all this was my reaching the limit of patience when a firmware "update" for the router sent it into a complete tailspin. So, to hell with the damned thing.

The only inconvenience is the fact I need to reset the cable modem whenever I switch its output from the desktop to the laptop - or vice versa. But since I won't be switching over to the laptop very often, it's not a problem of any significance. Thanks a bunch,
Jun and
Orion, for all your input on this!
