Nintendo WFC issues?

[phoenixlemon]

I've set up Dolphin 4.0.1 to play Super Smash Bros. Brawl nearly perfectly on my computer, but for some reason I can't connect to wifi. It doesn't *usually* give me an error thanks to this guide: https://dolphin-emu.org/docs/guides/wii-network-guide/ but i still can't connect, sometimes it will give me a different error or just freeze altogether.

Thanks for the help!

Enable Skip EFB Access from RAM under Graphics>Hacks.
Also, try one of the latest dev builds.

For reference, the above "Skip EFB Access from CPU" recommendation isn't nearly as random as it sounds – for some reason Brawl decides to use that feature somewhere in the WFC menus and it causes a ludicrous slowdown to <5 FPS.
