Strange wireless connection Issues

Specs: Windows 7 and Vista
Sorry if this gets a little long but I'm at a total loss as to what is happening.

I had the same setup for years without a problem, then my router went bad so I got a new one. Everything was fine for about 3 months and then all of the sudden last week my download speed on my desktop computer got really slow. No issues with upload speed only download.

Usually my download speed is between 15-20Mbps but now it's under 1Mbps. I have 2 laptops, one of which is in the same room, and neither of them has a problem. I've gone through all of the channels on the router and changed other settings and nothing worked. I moved the router with no success. I've tried different cables and I bought a new router and new adapter for the desktop and I still have slow speed. Now I'm back to what I had to begin with and of course I still have very slow speed. I even called the ISP just cover all the bases and make sure there weren't any problems on their end.

There is no problem with signal strength and the network speed usually stays at 54Mbps but never drops below 36Mbps when I'm connected.

On the problem computer I have Windows 7 and Vista both installed and the problem is the same no matter what OS I'm in. The laptops I use have Vista and XP, and like I said before there is no issue with them.

My router is a Linksys WRT54GS2 and the adapter I'm using now is a Linksys WUSB54GS v.2. I also tried a WUSB54GC adapter which didn't help.

Another thing that blows my mind is that I can connect to my neighbor's unsecured network and get faster speed than on my own network. Not as fast as I used to have but somewhere in the 3-5Mbps range. Another oddity is that once I connect to another network my network disappears. Sometimes it will reappear with full signal strength but then disappear again like it suddenly went out of range. All while I have 5 or 6 of my neighbor's networks in range.

There have not been any changes to my system at all so I'm completely frustrated right now. If anyone has any ideas what could be going on suggestions would be greatly appreciated.

connect direct cable to modem -run web speed test
connect wired to router - run web speed test
connect wireless to router -run web speed test
turn on all devices and from the best wireless signal -run web speed test

Make sure all units are malware/virus/ free. They are the precurors to hacker control of your network

I've hooked it up every different way. It's fine unless I go wireless and the computer is not right next to the router. Definitely no virus issues.

The thing about wireless is, you pay for the convenience. Wireless has inherent issues with insecurity, latency, lag and well, things like what are happening to you presently.

If it works just fine plugged in with a cable then the obvious answer is to leave it plugged in. The fact that it works fine plugged in and won't with wireless should tell you what it tells me, the wireless aspect is the issue.

Since the issue only arises on the one PC then that means it is either the wireless interface you're using or there's some kind of software issue like drivers for the wireless NIC.

If it were me, I'd try another wireless interface in the computer.......well no, actually, I wouldn't use wireless unless I had no other choice, I prefer a fast and stable network connection.......but you may want to try another wireless NIC. Just because the one you are using is new doesn't mean it isn't bad out of the box.

I've tried different NICs and routers and had the same issue. Like I mentioned before, the wireless connection worked flawlessly for months until last week. All drivers and firmware have been updated since the issue started. Before that I had made no changes to my system.

I'd love to just go wired but it would be way too much of a hassle to run the cables where I'd need them to go.
