IS and Win8

Hi all.
I have two computers running win8 a desktop and laptop, the desktop both with IS installed.
The desktop throw’s constant bsod, I know this is in the works for a fix.

Both computers have this same problem however, upon waking (I use sleep mode instead of shutdown) both have no internet connection, this stays like this for approx a min and then is restored, unfortunately its not always restored properly, and I find myself unable to access anything other than email, no browsing or other programs that connect work at all, it got so bad today that I had to uninstall avast from my laptop just to restore the connection, not even a shutdown and restart helped.

My desktop avast was uninstalled due to the BSOD as well as above.

Weirdly enough both worked fine whilst I was testing Avast, and the issues started after paying the sub.
Now I am left with a antivirus paid for and not able to be used on two different computers.

Thanks in advance for any insight’s you can offer.

although I do not have windows 8, out problems, incompatibilities with applications and are very vulnerable.

I think it might help
