Can I play online with hard-modded Wii?

I have a friend with a hard-modded Wii, and he wants to buy a wireless router to play online. But can you play online with a hard-modded Wii? – he wants to buy the router ONLY for this, so it would be useless if it won’t work.

I know that others asked similar questions, but no one specifically about hard-modded (mod chip) Wiis.
I think you can update the console with a chip, my question was more like:
“If you connect to the internet, do they detect the chip?”
