Internet/Network Erratic When Wireless PC Connected

July 19, 2013 at 13:55:42
Specs: Windows 7 Untimate, 2GB
I have another strange issue. I have DSL, an AT&T DSL Modem/Wireless N router, 2 Desktops with Wired connection, 2 Desktops, 1 Laptop and 3 phones with Wireless connection.

I have absolutely no issues until I connect one of the wireless desktops into the mix. As soon as I connect it to the network the computer itself gains network access and internet use. All computers including that one, now have erratic network and internet, speed slowing or no speed at all (speed test shows the speeds all over the place with an increase in latency). Another strange issue is when I go to speed test instead of being located in Nevada it shows that I am located in California. Without that PC connected it correctly shows me in Nevada.

Please and thank you for any help. Is the adapter bad? Could something on the PC be causing this?

The computer/adapter causing the issues:

Emachine W3644
OS: Windows 7 64bit
RAM: 4GB
PSU: 550W
WNA - TP-Link N150

So what happens if you hardwire those desktops into the network instead of connecting wirelessly?

Since you have both wired and wireless devices this is happening to I would suspect that wireless device is hacked/malwared and is calling home which by doing so is using up all the bandwidth.

Respond accordingly.

@Curt R
It is just one of the 2 wireless desktops doing this (there is also 2 additional desktops wired) and I will try and hard wire to see if there is a difference.

@wanderer
My PCs stay fairly clean unless I allow outsiders (guests) to muddle through them. This PC doesn't really see any action, it is mainly for Netflix. I have avast and malwarebytes but I suppose I will run them both just to see what they say.

Will let you know thank you.

Try connecting the desktop with a network cable and see if the issue doesn't go away and report back.

Ok, I ran Avast and found nothing, I ran MalwareBytes and found nothing.

I connected the computer to the network with a wire and no interference, speedtest doesn't show me to be in California, everything is normal just like the other computers.

So am I to assume that some how the usb wireless adapter is causing the whole network to slow down and speedtest to think I am in California? How does this happen?

That would be my assumption. You could confirm by connecting that USB wireless adapter to another computer and testing. If the same thing happens on a different PC then it's definitely the adapter

How does this happen?

Good question. From the sounds of it, and should the same thing occur on another computer in your LAN when you attach that same USB adapter to it and try to use it, I would suspect the device is flooding your network with packets. This can happen when an adapter goes bad. (Any network interface, not just a wireless one).

If you're really curious, download Wireshark and install it on the computer with the USB adapter and then enable the adapter and let Wireshark collect data from that. Then, disable the USB wireless adapter and enable the wired adapter and do another packet capture with Wireshark. Afterwards, compare the output of the two.

Awesome thank you. This will be the second USB wireless adapter to go bad connected to this computer then. What would cause wireless adapters to keep going out like that? Failing USB ports?

Location is based on the ISPs wan ip address. Nothing in the adapter can set location.

This location issue smacks of vpn like OpenVPN or similar service. Way this works is you connect via vpn to their vpn server and go to the internet from the services server. This results in showing a different wan ip and hence location.

Since this has happened twice on this device... good idea to test the adapter in a different pc to see if there are different results.

That's hard to say without more troubleshooting. The first thing you should do is what both wanderer and I suggested and try that device on another computer. This would prove conclusively that it is the device (ie: the same thing happens on a different computer) or it isn't (ie: issue is not reproduced when USB adapter is used on another PC).

The only thing I can think of besides a poorly manufactured device would be a bad USB port that's somehow causing issues with any device plugged in to it.

Well now my pin pointing was blown out of the water. After running the speedtest several times resulting in a high ping, low down/up speed and being located in California, I decided to shut down the network and leave one computer out of the mix each time I brought it up. When I left that Wireless Desktop out of the mix all my problems went away.

Now, though, one of my wired desktops is causing the same issue and when I disconnect it and restart the system everything is fine but with one issue. This time I will be back in Nevada but now my Ping is stuck at 42 instead of dropping back down to ten like when I would remove the wireless desktop. This is driving me crazy.
