If i were you i would stay away from wireless internet...
With wireless you need a excellent antenna to get a average / worth while performance. *With wireless technology u need very good signal strength and signal quality and also have a nice tower that don't give alot of problems*
Ur currently on wireless, from my experience you want to change to something else. Causeyur wireless is doing the following :
You keep disconnecting from Irc servers, or online gaming, or your internet just laggs for long times, or get huge ping spikes.
Your download speeds fluctuates all the time, then giving you 10kb per second, then 3kb per second, then like 1kb etc..etc *rollercoaster ride from hell*
Also your maybe getting alot of downtime / disconnections frequently??
How's my guess going thusfar ??

Get ADSL bro. Its pricy and its telkom ye, but at least u can expect better speeds *rather the devil u know....*
