Wired slow only when Wireless active

[GenericSetup]

I've had this issue with 2 different Linksys routers and now on a Netgear WNR854T wireless router.

Once the router has been up and running for a while with a wireless user attached the speed for both upload and download drop to very slow speeds.

If I disable the wireless radio on the router the wired speeds pick right back up to where they belong. All wired clients slow down, not just one workstation.

Normal speeds with wireless disabled:
10,717 kb/s download
992kb/s upload

Abnormal speeds where wireless client is attached and speed has dropped:
802 kb/s download
150 kb/s upload

This does not appear to be a workstation issue as all wired clients slow down once the wireless client attaches (takes a couple minutes or more before speeds drop).
If you do one of these then speeds pick right back up to where they belong
1. Disable the wireless radio on the router
2. Or shut down the wireless laptop

As said I've changed and used 3 different routers and all (even different brands) have this issue. The wireless client is an HP 800x series laptop with Vista Home.

Looking for a setting or something to resolve this wireless client issue.

The problem seemed to go away for a couple months, so wondering if Microsoft has modified some file on Vista that is causing the issue? Though very odd behavior and hard to believe that software on a laptop could make a difference to the hardware of a router, but frustrating as I can't find a fix for it for long time now.

Is your wireless secured? Or wide open? If wide open...curious if a neighbor is using your connection.

Nope it's AES secured. Have done with WPA-PSK and TKIP on the older router and WPA2 as well.

Have never seen anyone else on the system in the router logs or connection status pages. Even so, I would doubt that a single connection from a wireless (that would have a poor connection anyways if one at all) could drop the entire router down to 1/10 the normal speed.

I had this similar problem a few years ago with an old Linksys PCMCIA II card that was plastic, changed it out with a metal body Cisco version and the problem went away. The HP laptops though are built-in and I certainly don't want to buy and use another card because of this issue.

I just can't see how an external device like that could have an impact on the router but it does. Shut down just the wireless portion or the router and speed is right back to 10mb downloads for the wired connections.

Some kid running that peer to peer downloading stuff like torrents..yes a single PC can easily bog down most home and even mid-range routers with all those concurrent connections.

But if WPA or higher security..yeah doubt it's an unwanted wireless client.

I've never ever seen just enabling wireless slow down a router like that. Wonder what oddball things might be causing that. Done a wireless survey? Tried changing channels?

[GenericSetup]

Yeah, done all those things already. Weird as heck.

Just piss of the wife and kids and turn off the wireless :D

still searching for a fix...
