I'm on a G4 Sawtooth with processor upgraded to 1.4 GHz running 10.4.11, 1.75 GB RAM, stock 10/100 ethernet card, wired connection to modem (no Wifi). My ISP just upgraded my DSL to 25 mpbs (from 5 mbps), but the highest speed I can get is around 8-9 mbps down (a year ago I had the 15 mbps service and then too the most I got was 9 mbps, but I never questioned it at the time). The ISP technician was in yesterday to upgrade the wiring in the wall, and while I was only getting a maximum of 9 or so on the speedtest at speakeasy.net, his computer, also wired to my modem, was getting 26, so the slowdown would appear to be originating not in the connection itself or the modem, but in my G4. (I am getting 4-5 mbps up, btw.) The fellow at a local used Mac store (which no longer sells or supports PowerPC-era hardware or software) basically said, when I described my problem, "What do you expect? Your hardware and software are years out of date..." and that they basically can't keep up with current speeds, but he obviously had no patience for anyone still happily and productively using their G4 (not to mention a vested interest in guiding anyone he speaks to towards a newer system...). Is there any truth whatsoever to the claim that a G4 running Tiger cannot get speeds greater than 8-9 mbps down on a faster DSL line? Interestingly, the poster in this question: http://forums.macrumors.com/showthread.php?t=1621146 also mentions a much faster DSL line capping out mysteriously at 8 Mbps (though he does not come back to say if he ever solved the mystery of what was causing it). Anyone have any idea what might be causing this, and how I can fix it? I've looked through a number of posts here, and subsequently checked various Network settings in my System Prefs which people mentioned as being possible contributors to internet speed issues, but they were all set appropriately. Any particular reason why different people would find their internet capping out at 8-9 Mbps? Thanks in advance for any clues, suggestions, and/or solutions!
