I had this problem recently and managed to work around it by using a different wireless adapter. There are actually some wifi USB dongles that work with android out of the box.
The wifi dongle that didin't work for me was a TP-LinkIf brand one. The one that did work, was a DLink brand one. If someone's still interested, I can provide you with the dongle's model so you can buy it online. However, you can provably find other wifi dongles that work with android, you just need to check if it has a realtek chipset I believe.
