Slow download speed on my PC only, not others.

At the moment, basing off of Steam, my download speed sits in the range of about 150-600kbps (slower then my normal 1.5mbps). Another computer in the house will download at 3.3 mbps. That is his usual, which I didn't know until recently, and also means even when I thought things were fine, he was still doubling my speeds. I've been trying to figure out why because it's been particularly bad the last few days.

We have a netgear wnr2000 router. I have a wna3100 adapter. I tried his adapter (4100) on my PC and got the same speeds, and I tried my adapter on his PC and he got his normal speeds. I disabled my anti-virus (AVG).

The one thing I've noticed, is that if I got into the Network and Sharing Center, under speed his says: 300mbps. Mine maxes out at 54, often dropping all the way to 11.

I'm not particularly knowledgeable or skilled when it comes to this stuff, and I've been trying to find an answer on google to no avail. Any help is greatly appreciated.

Edit: Another bit of info. We are basically the same distance from the router. He is in the basement one floor below, and I'm on the floor above the router.

You could have some electrical wiring in your wall that's interfering, GOOD JOB moving the pc to experiment and get some changes going. Now go get an internal wireless card and download even faster :) that USB dongle is robbing you probably around 700mhz of your CPU power.

Two hypothesis based on what you're describing:
- it's the location of your PC, something is interfering with the signal quality for 300Mbps. Nearby electronics (<4 feet from your wireless NIC), cordless phone, something. Try swapping your CPU's to each other's locations and what happens?
- it's a setting in your wireless properties. I'm not sure that's it though, a different card should get you different settings.

The only thing I could think of near my PC that could possibly interfere is my printer, but that is hooked strait to my PC and is off unless I'm using it.

I'll try moving my tower to the same room as the router. I don't think he'd be down with me rooting around in his PC unfortunately.

From Netgear FAQ : "The WNA3100 is a single band USB adapter that complies with the official 802.11n 2.0 specifications. It operates at 2.4GHz frequency and works with 802.11b/g, and 802.11n wireless routers and access points. WNA3100 is capable of supporting wireless speed up to 300Mbps with 11n HT40 supporting wireless routers and access points."

Perhaps I need to manually set something in my PC to use the N setting?

Well, it is the room I'm in, or something to do with that. I lugged my tower down to the same room as the router (8 feet away), and I'm matching the Steam download speeds the other person is (3.3-5mbs vs 100-500kbs). Now I need to figure out what it is about my room that screws it up. The other guy and I have about the same amount of distance and walls between each of us and the router.

I moved the tower to the doorway, which did nothing. I slid it into the hallway, which puts it around the corner from the router (15ft), delivered somewhat better results. After that, physically carrying the router to the corner for line of site got me up to the connection I should get.

I guess I could say it's solved, but I'm still confused how the other guy can get a perfect connection despite being downstairs, while I have to have direct line of sight.

The speeds you quoted initially, 54Mbps and 11Mbps, tie exactly into 802.11g and 802.11b. Which is why I keyed on the g being the culprit.
