I've seen that after owners update drivers. I don't have a good cure but to head back to the stock drivers.
I have had and continue to have intermittent internet connection problems, which began after I reformatted my hard drive on the Acer 6930g laptop. When my computer goes into sleep mode, the internet will almost always be out and then come back on.
The internet connection may also go out intermittently when the computer is not in sleep mode.
