Left alone, wireless card goes slow

[Pete.]

I got a wireless network card in my pc, TP-Link something or other in a Dell PC running Vista.

If I use the PC fairly constantly I get 10-15MBPS. If I let the PC idle for a while I get 0.5MBPS if I'm lucky but still a really good ping. Re-start the PC I'm back up to full speed.
Plug in a Cat5 I get 60MBPS , but then I have a cable dragged across the carpet.
I've set the power profile to full power, turned off all power savings yet still if I get up in the morning or come home from work I have to re-start the pc before checking my emails or going online or I get dialup speeds.

No smart comments about Vista if you please, I know it's council-house windows but I needed a PC in a hurry and it came fresh-installed from a factory Dell disk. Ain't got time to switch to 7.

boot into a linux live distro, see if the same thing happens.

what a/v and firewall is on there?

got the latest drivers for the device, and all windows updates?

[Pete.]

Windows firewall and Avast Free. All windows updates done, driver off supplied disc.

Ain't got a linux distro to try, never used anything but windows.

When the speed drop, leave the laptop alone and reboot your router.

Let me know what happens.

Dell went through a phase of installing hideously bugged chipset and SATA drivers with their intel machines around the late vista/early 7 period (e.g. a pretty large percentage of Inspiron 1545s couldn't smoothly play a youtube clip out of the box). Go to the intel website and get the latest chipset inf installer and rapid storage driver for your mainboard chipset as a precaution.

Go with me on this.

When it gets slow, open up task manager and click the processes tab.
click the "show processes from all users" button or check box.

Take screenshots, upload to imgur.com and show me what is running.

Dont restart anything, i need to see what is running at that exact moment.

Cheers.

[Pete.]

Ok, I'll do that.

Strange that it affects wireless but not wired internet.

go to here Control Panel\Network and Internet\Network Connections then right click your adapter and select properties and the configure.

Do you have a option for sleep/power saving mode, post options if you can.

Gotta be the wireless driver that what my money is on

[Seb]

You updated the intel chipset and rapid storage as well as the wireless drivers?

Any more info on the wireless card would be helpful. If it's a PCI-E card, try setting the PC power profile to high performance and see if that makes a difference.
