I was having Widows 7 OS on my laptop. Both LAN adapter and Wireless adapters were working great! However, only one used to work at a time. I used to disable the other when a need one. I also installed widows 8 as dual boot. Windows 8 also works perfect on the two adapters. I installed VMware server 2.0.2 on the Windows 7 instance. I could not get RedHat VM working and hence uninstalled VMware server and installed VMware Player on Widows 7. Then I found another problem with RedHat VM and removed all VMware stuff.
Strangely, I realized that my Ethernet adapter encounter a problem - "undefined and no network access" (I see two Xs in Network and Sharing Center , one between "computer" and "undefined network" & the another between "undefined network" and "internet"). I tried all the tricks that are available on google search. None of them worked. I booted with Windows 8. It works perfect and I confirmed that there is no problem with ethernet adapter and cable to hub (no physical connection problems).
Any idea?
Thanks in advance,
