After reading the thread I'm somewhat under the impression that some of them simply don't know what they're talking about while some of them are willing to help you. Looks like they're just complaining about the 40 vs 20 setting, which they can easily fix in the server.cfg - they still talking to you?
Sometimes shareware packages come with annoying bundled packages such as Conduit, which while excessively annoying, are not actually malware or harmful. These usually have to be removed by hand via editing browser config files and registry values.
Sometimes issues like this can also be solved (if it isn't on the ISP or router end of things), by "uninstalling" the computer's wifi driver and the reinstalling from device manager.
