Using µTorrent with an ethernet connection

Hello everyone.

Previously I've been conveniently using my modem (Motorola Surfboard 4200) through a USB (2.0) connection. I noticed that with this connection, I wasn't getting my maximum download transfer rate (although I did receive my maximum upload transfer rate). I have a 12 Mbit/s connection with approximate maximum speeds of 1500 KByte/s down and 120 KByte/s up. With a USB cable, I get 670 KByte/s down and 120 KByte/s up. With a LAN connection, I get the maximum of both up and down.

I'm not sure why this is, and my ISP's support seems to have basically said "that's just how it is" (but those often don't really know what they're talking about anyway). USB2's transfer rate should be way more than enough to easily cover 1500 KByte/s. Maybe it's a limitation of my modem, I don't know... I'd like to hear your thoughts on this.

So far this had nothing to do with torrents; I used fast HTTP downloads for testing.

So, to get the max out of my connection with torrent downloads, I hooked up my PC and modem by LAN. But when I run µTorrent, it seems I can't get incoming connections (and the icon indicator is in the yellow state).

I generally (not only with torrents) have this issue with hosting things when using an ethernet connection rather than USB. I don't use any dialer such as a VPN connection to activate my internet connection, it's "activated directly". When I hook up via USB, my computer directly receives an outside IP address and recognizes it (my external IP address is shown in ipconfig.exe) and I can access the internet and properly host things as well. When I hook up via ethernet, naturally my computer receives an internal IP address (its address in the LAN, of course) and it's what's shown in ipconfig.exe (my external IP isn't shown there, I can only see it by e.g. going to www.whatismyip.org). I can access the internet, but can't properly host stuff (can't receive connections, I think). It appears my computer's software don't recognize my computer's external (internet) IP address, so they don't receive connections through it... one hosting program displays that it's listening on my INTERNAL IP, so obviously it fails to receive internet connections. This problem is solved if I hook up via USB or hook up via ethernet and use a temporary VPN connection (that I can't use full-time), in which case the IP I get from the VPN connection is shown in ipconfig.exe and is detected.

I guess the same problem is with µTorrent: it doesn't detect my external IP and listens on my internal IP instead. I probably don't have enough knowledge and experience with ethernet connections, so I'm not sure how to solve this, and have µTorrent listen on my external IP. I'd like to have all my programs detect and use my external IP automatically (like they do when I use USB), too, rather than have to configure each one (... and again whenever my IP changes). How would I do that?

For completeness, note I always hook up the modem directly to the computer, with nothing in-between, like a router. I do have some routers handy, but I don't really feel a need to use them for this PC at the moment and I'm satisfied with my software firewall (and I don't wish to have to create rules and "forward ports" on both it and a router).

Thanks for reading (sorry for the long post) and thanks for advance for any help.

Don't think so. That not really making much sense aside, AFAIK it's just a modem, and definitely not a router-modem combo.

I'm pretty sure how to solve this is kinda common knowledge, but I'm not sure how to find it or how to call it, so I made this topic.

The modem's internal functions, which do that but don't include full router features such as a firewall and other security functions and routing data to different computers in the network (it can't even physically connect to other computers in the network, of course), unless it is indeed a sneaky modem-router combo. I'll verify that soon.

Note that I asked 2 separate questions in my original post. Nobody knows why I don't get my full downstream rate using USB to begin with?
