Fast internet connection, SLOW page load

PeroMHC · #1 October 21st, 2008, 07:50 PM

HELP

I recently bought a 1TB TC, and since then have experienced very slow internet page load times. The connection is fine: Upload=11.3Mbps, Download 7.55Mbps, but page load times are very slow.. In fact, my iPHONE is loading pages faster than the MacBook Pro.

Slow load times are experienced in both FireFox and Safari, which makes me think that it is not a browser problem, but rather a problem with the TC itself.

I'm using the 802.11n (b/g compatible), 100% transmit power..

Any suggestions?

Fast internet connection, clean install, Leopard MacBook intel, and it does not matter whether I use Firefox or Safari, there is a long delay of at least 4 to 10 seconds before the page (any page) begins to load. I, too, would appreciate any help.

First thing to do is run this Trojan Horse removal tool:

Next possibility is poor DNS response. Add an OpenDNS server to your Network Prefs TCP/IP setup from here (bottom right of page, 208.xx.xx.xx):

But why would poor DNS response be limited to wireless connection? I have a computer in the house hooked up via ethernet cable, which works fine.

If I understand DNS correctly, this has to do with the link between my internet service provider and "the internet". In other words, if it were a DNS problem, then both wired and wireless connections would suffer similarly slow page loads.

Maybe I am misunderstanding?

I'm glad you have questions....
Have you tried the troubleshooting steps I suggested? You can't solve any problem without troubleshooting.

Yes. Sounds perfectly like the trojan is behaving. Basically messes up your DNS queries. Get rid of it.

yep, just tried the trojan horse scan- not detected. I tried openDNS a few nights ago with no improvement. Sorry I didn't mention that in the OP.

OK, thanks for the info.
Because of firmware, wireless can definitely act differently than ethernet. But let's take a first guess that it is still an OS X software problem - most likely a corrupted file.
Do the usual troubleshooting steps:
1. Read various online services to see if others are having this issue. They are.

2. Think about what else you might have changed recently that could be related, and figure out how to reverse or re-do it (Security update that may have gone bad, etc).
3. Start from the Install DVD and repair the hard drive (and permissions while you're at it:

(down where it says try disk utility)
4. Download the latest Combo Updater and re-Update with that.

Good luck.
