I have seen several other post with similar, but not the same issue, and none of which had resolutions. I have a clean install of Windows 8.1, all updates applied, latest BIOS, and all drivers from Acer site installed - including the latest wireless Atheros v10.0.0.276.
With a constant ping going you will see ping times from 20ms to 1500ms and a lot of drops (packet loss). Three other machines on the same wifi without issue. It is basically unusable it is so poor. I am not sure what else to try at this point. I have taken some suggestions from other forum discussions, but nothing works or really seems to be the exact same issue.
Out of options here, so hoping someone has further suggestions.
Thanks in advance
