How to change WiFi adapter driver

during installation I was offer two drivers I went with the default one but now I’m having problems, so I can see why I was offer the other one, so I would like to switch with out having to reinstall; would this be possible. here is what I have now
Device-1: Qualcomm Atheros AR93xx Wireless Network Adapter driver: ath9k
IF: wlan0 state: up mac: e8:de:27:08:d1:c1
Device-2: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet
driver: r8169

You can run again the “Welcome” script, but the options are for your wired driver (realtek), not your wifi (atheros).
