About a year and a half ago I installed a gateway wireless broadband router to my fathers computer located in the downstairs living room. This computer has cable high speed internet. I also connected a gateway usb wireless adapter to my computer located upstairs. When I first installed it, I had high speed internet. You could barely tell it was wireless. But these past couple of months my internet has been very very slow. The connection cuts in and out and sometimes it wont connect at all. I have tried almost everything. I scanned and cleaned my computer with ad-aware, spyware doctor, registry mechanic, Hijack this, bullguard. I also scanned it with trojan hunter and nothing apeared except under file scan, it said Error: Directory not found:C:\Documents and settings\all users\ Start Menu\ Programs\ Gateway USB-G Wireless. After I read that I reinstalled the usb wireless adapter to my computer, but still no change with my connection. I also dowloaded winsock XP Fix but no change. I don't know what to do. I cant help but think im infected with a virus since the connection from the downstairs computer is so good. If someone can help me please post.

I would be thinking one of two things,
1-malicious code (spyware, adware, worm,etc)
2-wireless interference.

for problem 1, please DL and run HiJackThis, and post a log int he proper forums.
for problem 2, please read the following,
on another note, why dont you try to plug in your computer directly to the router to see if your connection speeds up a bit. here is the wireless interference bit.....

Going wireless is an exciting milestone. Whether you're in the process of setting up your network or you've already been working happily without wires, you're probably familiar with Public Enemy Number One in the wireless world: interference.
If you've experienced interference, you know how annoying it can be: now you have a signal; now you don't. It's like hide-and-seek.without the fun. But wait! Don't throw your hands (or your laptop) in the air. We'll tell you how to determine what might be affecting your signal, and how to get back to being your old productive self.
What is it?
Think of a time when your favorite radio or television station wouldn't come in due to bad weather. When the storm passed, the signal became clear again. Similarly, because your wireless network relies on radio waves traveling through your home, your signal may waver for a variety of reasons. How will you know if you're experiencing interference in the first place? We'll help you identify and solve potential problems.
Check your signal
Thankfully, the client software that comes with almost all wireless network adapters can help you monitor your network's performance. With most systems, there will be a signal-strength meter in the Windows system tray (usually found in the bottom right corner of your screen).
In addition, the client software itself probably has a more in-depth system for testing signal strength. This feature is commonly called a link test function, although it may be called something else (depending on the manufacturer). Check your manual or the online help system, which usually measures:
Signal strength: Measured in decibels compared to one milliwatt (or dBm), the signal strength is sometimes referred to as signal level. The higher this number is, the better chance you have for a full-speed connection between your access point and your PC.
Noise level: Ideally, you want the noise level (also measured in dBm) to be as low as possible. Cordless phones and microwaves are common culprits for increasing the noise level.
Signal-to-noise ratio (SNR): This is the most telling of the numbers because it compares the strength of the signal with the noise that is interfering. SNR is measured in decibels (dB), and a higher number is good news.
Placing your access point
The location of your access point (AP) is key. With a little planning, you can avoid potential interference and save yourself time, money, and frustration.

Here are some pointers:
Pick a place near the center of your home.
Avoid mounting your AP on the wall. The best place is six or more inches from the wall.
Keep the AP out of the line of sight of microwaves, cordless phones, refrigerators, and other appliances that contain metal.
Your computer can cause interference, so try keeping the AP separate.
Avoid putting the AP low to the ground. Instead, keep it on a table or a shelf.
If your house is large, you may need two access points.
Troubleshooting tips
If your wireless network is all set up and you're experiencing interference, here are some ideas for improving the signal:
Move the access point. See the above section for pointers, and if all else fails, walk around with the AP while someone else monitors your signal strength.
Change channels. If you've got a neighbor with a wireless network, you may be operating on the same channel. You can change the channel in the software that came with your wireless access point.
Move the antenna. Not all antennas have the same range of coverage, so finding the best position is a matter of trial-and-error. Try moving yours around and changing the angle.
Change phones. If you have an 802.11b or g network, consider one of the newer 5GHz cordless phones. If you have an 802.11a, try a 2.4GHz phone. Better yet, an older 900MHz phone won't interfere with either type of network.
Check other network obstructions. Other network obstructions include ceramic tile, concrete, and even stacks of newspapers, as well as Bluetooth-enabled devices such as laptops and PDAs.
Consider an upgrade. If you're using 802.11b, you might have better luck with the newer 802.11g devices that have more non-overlapping channels and less interference. Plus, they're almost five times as fast!

Hey, I tried most of what you suggested and my internet is working better now. I think moving the router is what made the difference. Although my computer is still a little slow it runs much faster than before. But I cant figure out why when I do a full system scan with trojan hunter it says Error: Directory not found: C:Documents and SettingsAll UsersStart MenuProgramsGateway USB-G Wireles????? And the little TV that is usually at the bottom right of my monitor that shows the strength of my signal isn't always there. should I reinstall the usb adapter. And if so how do I do it. The instructional booklet only shows how to do it from unidentified device found, so obviously when I hook up the device it recognizes it even if I uninstall. I'm confused :thumbsup: I dont know, I just might connect directly to the router so I can stop dealing with all this bs. Anyways, thanks for your help I appreciate it.

right click on "my computer">properties>hardware>device manager, right click on the networking device/usb 802.11 adapter, uninstall it, reboot, then reinstall the device, and it's utility. have you updated your windows os to service pack 2 yet? and checked for othewr updates? have you run more spyware tests, and found a lot of results? let me know
