W-LAN probably makes the most sense. Aside from Wi-Fi being what the Wi-Fi alliance came up with, and definitely more catchy than its prior name of "IEEE 802.11b Direct Sequence," at least "W-LAN" has a meaning. English speakers are familar with Hi Fi, and Sci Fi, but not Wireless Fidelity or Wireless Fiction. So we have something that seems like it should be short for something, but isn't anything more than a marketing tool, unlike most high tech terms.
"We fee" could be the slogan of a check cashing company, trying to be honest about their charges.
