plug on plug off

hey,

when i have my macbook plugged in, the internet works super fast. then when i go portable, he internet works sooo slow and often don't even load the pages. this is on the wireless network, sitting in the same place. this happens on both safari 3 beta and firefox 2. what is wrong here?

My internet works same with or without the ac adapter plugged in. My airport (wireless) connection is the same strength.

it remains the same signal strength

but it certainly does not act that way

please help

Are you referring to having he power cord plugged in vs on battery, or when using an ethernet cable vs wifi?

i am talking about when the power cord is or isn't plugged in. I am always on wifi. its extremely fast when i have the power plugged in. it slugs or doesn't even load pages on battery.

and i am talking about when i am sitting the same spot, same signal, same internet connection.

I think you might have a problem that would be best handled by taking it into an apple store, if possible. It was easy enough for me to test this with my own Macbook by unplugging, being on wifi, and it not being any different regardless of whether being plugged into power or not. I had the thought that one of the cores of your CPU would perhaps be disabled when you unplugged the power, but that wouldn't really cause a noticible network slowdown under normal circumstances.

Since this is something that you could probably reliably duplicate on, say an Apple store's wifi network that might be your best bet.

i am 200 miles away from the apple store.

this problem started occuring on 6/24 when i got the recent os x 10.4.10 (intel) update

You may want to give them a call. I presume your MacBook is still under warranty.
