Starting about a week ago, the wireless connection on my Macbook slowed down considerably. With an ethernet connection the internet works fine, but when I'm using the wireless network everything slows to a standstill. It's definitely not the wireless network--I'm using my school's wifi, and I tried a friend's identical macbook to confirm that it's just my computer and not the network. I ran an online speed test and got the following results:

(wireless) 1.23 Mb/s outbound, 75.48 kb (kb, not mb) per second inbound
(ethernet) 2.41 Mb/s outbound, 1.70 Mb/s inbound

I've tried doing some research online to figure out the problem, but there are so many things that can cause wireless problems I've been having a hard time sorting through all the information. Does anyone have any suggestions as to steps I should take to determine the source of the problem? If it helps, here's the information for my computer:

I'm not sure what kind of router it is--it's my univeristy's wireless network, so I don't have access to the router or any hardware. However, I've tried it on multiple wireless networks that worked fine for me up until a week ago, and now they're all going slowly.
