Where it happpens: Right-side USB port (MicroSD slot that side) with PEN-DRIVE plugged in
How it happens:
- My Rapoo BT mouse connection is disturbed result in unstable cursor movment, and WIFI not able to connect to my wireless access point(TP LINK 50A75B portable multipurpose access point)
- Only Acer BT mouse able to work so far
- When I turned off PEN-DRIVE by Safely remove device(not even pulled out the pendrive), WIFI can be connected again to my wireless network.
Summary of the issue: USB port active, WIFI and BT fail; USB device safely removed, WIFI and BT back to normal.
Attempted solution for failed:
1. remove existing BT and WIFI drivers and installl the latest downloaded from Acer Support
2. This is not my first S7-191 having this problem, I asked one-to-one exchange from the Technical dept, but this new one is giving me same problem, so its either mainboard defects in massive no. or simply the driver issues.
Other things to take note:
1. The included Acer BT mouse with my first S7, is faulty physically(not able to do left-click consistently), but the 2nd S7 Acer BT mouse is working normally.
2. Not sure whether other acer software are conflicting with Win8, but I am prepare to wipe the ultrabook clean with Win7 64 bit with downloaded driver.
