ATTENTION!
If you don't have the CIOS, but have the Homebrew Channel, you can STILL downgrade. If not, stop reading this.
Follow these instruction to downgrade 4.0. I recommend 3.2 because the Twilight Hack will still not work, but if you ever lose the HBC, you can copy it back to your Wii from the SD card. Only works with 3.2.

Follow the guide over at GBAtemp carefully.
EDIT: If you do want to update to 4.0, but not lose any features, use Waninkoko's 4.0 updater. This updater updates you to 4.0 without replacing the old IOSes with new ones, and updates the Wiishop channel with the all new SD Menu.

I still do not take any responsibilty for whatever happens to your Wii. Use at your own risk.
This downgrading process does NOT work with System menu 4.0. Don't bother asking for help if you updated, it's your fault, I will not be helping you with 4.0 until a new process has been established.

FAQ
Q: How come I get keep getting Error!Ret-(number) when trying to install (name).wad?
A: Try using the cIOS_249-rev6_rr.wad. It's the same as cIOS, and it worked for me. I was on 3.3 when I used this, so it might be required fr you to have it.
Q: How come cIOS_fix.wad won't install?
A: You're probably using the Wad Manager, and not the Custom one that was meant to run on IOS16 or, your Wii is not on 3.4. If it's not, use the cIOS_249-rev6_rr.wad.
Q: If there's cIOS_249-rev6_rr.wad for 3.3, and cIOS_fix.wad for 3.4, what's for 3.1?
A: I have no clue on that, but I assure you that both those .wads should work on that firmware.
Q: I am getting errors on everything.
A: You probably didn't install both .wads.
Q: How come IOS Downgrader stopped?
A: The program crashed if it's a block of text; an error occured while the installtion was taking place. Just run it again. If it still keeps doing this, fix your internet settings.
Q: Why downgrade to 3.2?
A: Because Starfall only works on 3.2. If you don't want to do the Starfall step, you don't need to. It comes in handy to skip disc updates.
Q: I'm still getting errors!
A: If you Installed the cIOS for the Backup Launcher, uninstall it. That should fix your problem(s).
Q: Can this brick your Wii
A: Yes. That's if you missuse these applications. This is at your own risk.
Q: You owe me a new Wii.
A: No, you didn't read the description. I even stated that I DO NOT take any responsibility to whatever happens to your Wii. It's your problem.
Q: Is there a way to unbrick my Wii?
A: Plug an open Gamecube controller into the Player 4 socket of your Wii console. Press Up + Down + Left + Right on the D-pad while your Wii is booting up.
Q: I have a question not answered here.
A: Explain your problem on this video.

Sigh. Your Wii's bar code is probably LU64+. LU64+ Wiis cannot be downgraded, as it is impossible as of now.
