Wrong driver on the cd provided, the driver was for intel wifi adapter.
Acer usually manufactures their notebooks with either Intel, Broadcom or Atheros wifi adapters, and in my case it was Broadcom.
Acer Aspire 5610z Broadcom Wireless Driver XP - 73.3Mb
Acer Aspire 5610z Atheros Wireless Driver XP - 1.6Mb
(If you are unsure of your wifi model, turn around the laptop and look around if somewhere reads atheros. The models with atheros adapters usually have a small text where the model of the atheros adapter is printed.)
