Just purchased an Asus RT-N66R, that came with these utilities. After install, I noticed RawEther NDIS 6.x protocol was now installed on my Network Cards. I configured router w/o using ASUS utilities. Just did it with a browser, so decided to remove the Asus Router Utils. All went fine, but I noticed later that the RawEther NDIS 6.x was still there. The uninstall did not remove it. I don't like sloppy uninstalls, so I decided to clean it up myself. ( The RawEther NDIS 6.x appears to have been installed as part of the printer support for the Asus? ) assumption. It was just a question of removing that protocol from from any network interface, and it removed it from all of them. Comp is Win 7 64bit SP1. About an hour later, I enabled my wireless interface to check router signal, etc etc. Surprise!!! No good! Once that RawEther NDIS 6.x was uninstalled, my wireless ( RaLink PCI-E ) card would not enable. It said it was enabling, but never did. Properties on the card showed a speed of 412.3Gb in the windows status window. I wish!! I googled that, and came up with a few situations where people had the same speed listed in their status as well. Their card types were wireless as well, but their manufacturers were different, and their OS was different in many cases. But their symptoms were very similar. Luck for them they were not running Win 7 64 bit, so there were options for them to get a working NDIS stack reinstalled. Win 64 requires signed drivers, no exceptions, unless you go through the F8 startup & turn off driver signing for that particular boot. This did not work for me. I'm angry @ Asus for not having a clean uninstall program & at myself for ever installing the utilities in the first place. So for now, until I reload my O/S, no wireless. Wired works fine. Good luck!
