Vinatec, thanks so much for the help. I didn't even bother with any of the wanin or hermes as wads. All I did was download the new cios 249 rev.17 and installed it by using WAD manager, and it worked like a charm! Just doing this simple fix drastically increased the performance of my Wii. Many thanks to all of you who helped me out on this!
Oops sorry, let me correct myself. I think I did install cios 249 rev.17 as a wad thru WAD manager. I am not sure whose cios 249 rev.17 I installed as a wad, whether it was Wanin or Hermes. Oh well, all of that doesn't matter much now because at least I got the Wii to perform a lot better with this update....
