Sadly not (At least the site says so, W2K SP4 and XP only) KernelEx maybe worth a shot, although KernelEx does not work well (If at all) with drivers...
Be prepared to manually uninstall and delete in case.
WPA2 has been always problematic in Windows 98, there are ways of obtaining WPA2 like Odyessy Client 3.1 to 4.52 (Discontinued Wireless Utility), Wireless Cards (Requires installation), Card buses (Be very careful which one you buy, some do not work with Windows 9x despite being adv'd doing so), Wireless USB adapters (But like mentioned, maybe cause issues, these same issues maybe present in card buses as well), or changing your router's settings if possible. I'm somewhat confident there must be some sort of Wireless Utility released back in 2001-2008 that contained WPA2 with 9x support. We just need to look for it...
Biongo Wireless Utility (Archive.org version doesn't support wpa2)
