I'm having awful problems with lack of speed on my wireless broadband. I'm wondering if it might conceivably be a setting on my computer that's the problem. Here's my system: I have a G4 15" PowerBook running Panther. I'm using mostly Safari and Eudora. The broadband comes from an antenna on the roof pointed at the Guinness tower in Dublin. I downloaded Speed Download to try to measure the kind of speeds I'm getting, and it's showing my download speeds as an average of about 5k/s for a game demo I downloaded, and then after my broadband provider tweaked my settings, about 27k/s from the Apple site for...something, not sure what it was. iCal maybe. The support guy in my provider found that he could push 220k/s through my system - but meanwhile from this end my system is as slow as ever. He's calling in the big guns - but on the other hand, I don't want to waste their time if it's possible that the problem is with my computer's settings or system. Is there anything I should do to speed the system's connection to the internet?
