This is driving me crazy, so any help would be greatly appreciated.

I am using an IBOOK G4, running OS 10.3.9. Never had any major problems with the computer itself....

I am currently living in Korea, and thus have very highspeed internet. However, on my Mac, it is running quite slow.

There is no modem that I can reset, because the apartment building is already wired so my ethernet cable connects directly into the wall.

A friend came over to test the connection (speedtest.net) with his PC and he was downloading 60,000 KBPS, when I plugged in my MAC I was downloading at 15,000 KBPS. He downloads various things at around 2mb/s and I sometimes only get 50 kb/s.

I've tried creating a new network location, resetting firmware, unplugging the cable, and changing to full duplex.

Any ideas? :confused:

yes, I changed them to the OPEN DNS servers. Did not help though.

speedtest.net is flash based and does not show your actual speed if your cpu is being consumed with the flash portion. Your computer is very old thus flash might be taking 100% of your CPU, leaving little room to process your downloads.

Download a trailer from apple.com/trailers
and see what download speed you get from that

I assume you are using the same ethernet cable for both the PC and the Mac. You could try a different user account. I don't know why that would help but it is worth a try. If you have your OS CD's an archive and install is the shotgun approach to software issues. Ideally you would boot your computer from another drive to see if it is software or hardware.

Since you have access to a high performance network (60 Megabit), its work checking some sysctl parameters that govern TCP windowing and socket buffers.

Open a Terminal window, and type the following:

sysctl net.inet

Paste those results here.

Also, check the socket buffer settings with the following command:

sysctl kern.ipc.maxsockbuf

Paste those results here as well.

Thanks for all the advice so far.

I did try to download a trailer off of apple, but none of links I clicked on would actually begin a download. x_X

I do understand that the flash based speed test can be completely inaccurate, but all the files I have been downloading have been quite slow as well. 400 kb/s MAX. :/

Also, I just finished formatting - just to be sure there weren't any leftover setting causing bugs...but internet speed remains the same.

Lastly, I opened terminal and typed in those commands. This is what returned:
