windows 8 lenovo desktop interfering with other devices wifi

March 18, 2014 at 18:41:19
Specs: Windows 8, core i7, 8GB
I have a strange networking problem.

I have a newer Windows 8 PC - Lenovo IdeaCentre a730 desktop. When the PC is powered on other wireless devices on the network have trouble keeping a good connection to the internet. The wifi signal is strong, but connection issues persist.

The windows PC has the wireless disabled and I only use the gigabit hardwired NIC.

How could this PC interfere with other wireless devices when the device's wireless is off?

I have AVG free scanner and all is fine there. Rootkit scan is negative.

How is the wireless disabled? If possible disable it in bios setup. Otherwise page 11 of the manual:

http://www.lenovo.com/shop/americas...

describes how to access the network settings in windows 8.

Of course it might be some other interference. How close is the PC to the other devices being interferred with? You may need to isolate the PC through another circuit or use an AC interference filter.

It is disabled in windows. I could try doing in the bios.

The wireless devices are all over The house. It affects another network that it is not even joined.

Let me try bios.

Looks like the BIOS wont allow disabling just wifi. You have to disable the whole controller.

I have unplugged the wireless keyboard and mouse to see.

I ahve in the past re-flashed the OS and the problem goes away for some time. Then comes back. this leads me to believe it is somehow virus related.

You're getting a lot of things mixed up here. First off, most desktop systems do not come with a wireless network card. I doubt your system has one, and I doubt it's somehow interfering with the wireless signal to your other devices.

"I have unplugged the wireless keyboard and mouse to see."
Wireless keyboards and mice use a bluetooth connection with has absolutely nothing to do with your wireless Internet connection.

"When the PC is powered on other wireless devices on the network have trouble keeping a good connection to the internet. The wifi signal is strong, but connection issues persist."
How could this PC interfere with other wireless devices when the device's wireless is off?
Your PC is not interfering with the wireless signal, my guess is that your PC is sucking up all the bandwidth on your Internet connection. I think your assumption of having a virus or malware is most likely the cause.

I agree but none of the tools have detected a virus. Any other suggestions of tools?

I did a reset of the OS. Back to normal.

I tried tvn network monitor. It could not get it to work on x64.

I would like to see what it is doing. My data is not on the PC anyway so a falsh or reinstall of OS is easy.

'Back to normal' meaning it's not interferring with your other wireless connections?

Keep track of any changes you make with the PC--hardware additions, driver updates and setting changes--and see if they match up with the problem starting again.

I will keep track.

Back to normal as in wireless devices are all OK.

I have now installed McAfee from att uverse.

Any other good preventative measures?

Can't think of anything offhand. We'll have to wait and see if any change can be linked to the problem starting again.
