I bought a brand new laptop, HP17 G053US from Office Depot. It came with OEM installed Win8.
It was working fine, no problem with using the wireless card. I can not quantify the signal strength received, other than to say it was 3 of 5 bars, same as an adjacent laptop.
I have since reinstalled Win8.1 Pro x64. The WLAN now no longer detects any signals from any wireless routers/modems. Zero of five bars (while adjacent laptop still shows 3 of 5).
I loaded the drivers in sequence BIOS, chipset, then WLAN. To no avail.
Is there some way to adjust the sensitivity of the WLAN?
(had some trouble posting the image)
I suspect there may be some way through Device Manager Advanced Properties of the WLAN?
Also noticed that there are a few unrecognized devices - perhaps one of those may be related...
