Lets give clint the benefit of the doubt here and i would suppose that there be some happy people on wireless.
Wireless does have a place, however only if ADSL is not available. DSL is better and anybody that has ever had wireless will tell you this. ("wireless" means making use of technologies OTHER than WBS, sentech, HSDPA or GSM based technologies.)
Lets do the math. DSL192 + 3GB of SAIX on Cybersmart will be R370. okay for this you get reasonably stable pings and a reliable connection.
I have had DSL for months and have never had to make a single call, with the service being down or slow. With wireless on the other hand, calls were a daily occurance.
Even if DSL costs R100 more a month, in the long run, its not worth the stress and doubt.
These wireless operators seem to be greedy and instead of servicing 50 clients properly, they attempt to service 100 clients 50% of the time. they often don't have proper call centers or expertise. I'm not saying telkom is much better.
But I cannot push the point enough. If you are considering getting wireless, ask for a 14 trial. do this before you pay a cent because ultimately you'll be sorry and then you could have spent your money better.
Some of these folks are out there to take your money and please just watch out, rather share a DSL line with your neighbour using CAT5. then you split the bill and bandwidth.
Internet should make life easier not, more problematic. There are no bodies to regulate these people. Get them to sign a money back guarantee, if they are that confident of there service, they should put it on paper. I'll help you sue them!
