Hi, same issue and I have installed the chip set but it hasn't resolved the issue.
System:
Windows 7 Home Premium 64bit
Acer Aspire 5820T
Hard drive blew so had to replace it and reinstall windows, however these two devices Network Controller and PCI Simple Communications Controller issues are not installed correctly with error message in Device Manager of (Code 28) for both.
I have installed all appropriate drivers from Download
these being:
Chipset Intel Chipset Driver 9.1.1.1024 2.3 MB 2010/04/08
Lan Atheros LAN Driver 1.0.0.33 4.6 MB 2010/06/23
Modem LSI Modem Driver 2.1.94 1.4 MB 2010/04/08
Wireless LAN Atheros Wireless LAN Driver 8.0.0.259 21.1 MB 2010/04/08
However the only device that was activated correctly after installing these was the Network Adaptor.
I therefore have no internet on this machine due to these two devices not being activated.
Please help.
I have phoned Acer but unless I go to there Premium support number at 50p/min, they can't help me.
