(Sorry, I just edited this because I realized the title said Wireless Router, it's actually a gateway. Can't fix it.)

I have a Netgear CGD24G Wireless Gateway and a Gateway MA8 laptop with after-market Windows 7 (Vista got a virus, went ahead and upgraded.)

Now, when I download 100 MB files on my Xbox 360 (Which is wired to the modem) it will be downloaded in a couple minutes, or less. The other computers in my house (There are plenty, and even more that come and go.) get a blazing internet connection, and most of them are wireless. Now this computer, which had an extremely quick connection as well all of a sudden dropped off, while the rest of the computers remain fast.

I've gone to Speedtest.net before and after this occurred and my speed before was around 12 mb/s, and one time around 4 AM was even upward of 25 mb/s, all of these tests were performed multiple times on different server locations.

I JUST did the speedtest, and it came back with .4 mb/s, and the UL speed was 2.0. I honestly can't remember what I averaged with it prior to the problem, but it was definitely higher as well.

This started happening a little less than a week ago, and I've downloaded/changed nothing major with the computer, and have mainly used it for light browsing, and an occasional download.

Also, this is mainly just a hobby fix. I have a long enough cable to wire the computer straight to the gateway, so I really don't want to buy new hardware or anything of that sort. I just wanted to see what could be done about this.

Thank you

(Another edit: I just tried this in IE, because I realized I hadn't tried it with another browser, but the result is the same.)

No need to bump more often than after ~24 hours.

Have you checked with an ethernet connection to determine if this is a wireless issue or more general?

Make sure you have the latest wireless driver--from the PC manufacturer's web site if an integrated adapter or adapter manufacturer's site for an external card.

Please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector. And please show ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

Okay, first thing, I apologize for bumping so soon, this seems to be a popular site so I was under the impression my post would have likely traveled to the back pages of the forum this quickly. I'll keep it in mind though, because I definitely plan on using this site again.

Also, I tried it wired and I got 16.83 Mb/s DL, 2.03 Mb/s UL. Considerably faster download, pretty much exact same upload.

I'm going to download the latest driver right after I make this post. Also, I just checked on one of the other computers in the house, I definitely should have before I posted, but it seems to be going the same speed. It may just be a problem with the gateway.

Another question, would you like me to post the ipconfig while it's wired or no?

Also, drivers are up to date.

No need for another ipconfig /all. I mostly wanted it to see your OS and wireless adapter and if anything unusual showed up.

You got the Xirrus monitor (which I like to use all the time just for a quick check). Usually we want to look at the Networks page of the Inspector so that we can see all the networks, their encryption and channel and strength. However, from what you've showed it looks like you have a decent signal strength and no other network strong enough to cause interference.

Given all this information you've supplied, including that last bit about another wireless computer also getting the slow speeds, I'm suspecting a router (gateway) problem. Assuming that it's not under the control of your ISP you can make sure you have the latest firmware and then reset it to factory default settings and reconfigure it. Make sure you know how the router's WAN section is configured before you reset it.
