Ok, first, task manager can’t give you useful information about your connection speed. It’s looking at the wrong thing. It’s looking at the connection between your network card and your modem. That connection is very fast. But the issue at hand is the connection between the internet and the modem, which is much, much slower.
Suppose you had a 100 gallon-per-hour fire hose, and you used an adapter to hook it to your 15 gallon-per-hour water faucet, then turned on the tap. You’d still only get 15 gallons per hour, even though the hose could carry much more, because that’s all the tap can deliver. It’s similar to that.
The problem boils down to your listening port being blocked. That “timed out” message tells you that. If you unblock the port, then other peers can initiate connections with yours and that will greatly boost your speed. Those are the “remote” connections.
It isn’t safe to connect to the internet without a firewall, and a firewall’s job is to block incoming connections except for ones you know about and want. Windows XP has a built–in firewall, and if you installed Service Pack 2, the firewall is active by default. Some people also install other firewall software, or install software they don’t realize contains a firewall.
Next, some external hardware like modems/routers, also have built-in firewalls, which are called “firmware” firewalls.
Yours is almost certainly a firewall issue. So we need to figure out which firewalls you have, and remove or deactivate all of them except one. You only need one, and having more than one just makes them stumble over each other.
The test at canyouseeme.org is your definitive guide. If it says your port’s still not open, then there is still something blocking it that we have to find.
You said that you portforwarded your modem and that it was a Motorola SB1000. I’d like you to double-check that model number first, because it doesn’t seem to fit.
When you portforwarded it, exactly what did you do, and according to what instructions? Do you have the url of a web site you followed? Specifically, did it direct you to set up a static IP for your computer, and did you do that?
