We have a home network & connect our various devices wirelessly to a modem.
This includes a PC (running windows 7) that connects using a PCI-wifi card (and antennae). This PC seems to seems to be causing a high ping + slow/unreachable internet connection. We confirmed this by enabling / disabling the wireless adaptor while running a speedtest. The speedtest is unresponsive / shows a high ping while the adaptor is enabled and as soon as it's disabled, the speed-test needle / indicator jumps into action & we get a reasonable internet speed.
Other computers connected to the network don't cause any issues and only experience slow or no internet once the PC in question is connected (PC is on & wireless adaptor is enabled).
We've installed & run Avast! + Microsoft Security Essentials on the PC which haven't turned up any issues. I've also tried disabling any suspicious looking tasks, which also didn't solve the problem.
This leads me to think that the problem might be hardware / configuration related.
Is it possible that from the symptoms described above that this could be a hardware issue on the PC, or possibly the way that the internet settings are configured?
If so, is there any way to troubleshoot this and try get to the source of the problem?
Thanks
Tracey
