You got sound advice on how to go about getting help to solve your problem. You haven't provided much relevant information, and certainly didn't in your first post.
That's great. Re-read this paragraph- what are we supposed to do with the information you provided? You've described the symptoms, any of which could be due to any number of different causes.
Then provide some useful information, if that is not too much trouble. MisterMe's response wasn't supposed to be condescending, it was meant to inform you that your original request for help cannot be acted upon further without some necessary information.
You could start by posting the exact specs of your Macbook as found in Apple Menu -> System Profiler (processor, amount of RAM would probably be most helpful).
Then, you could briefly describe what you use your network for. Is your roommate viewing text webpages while you're trying to view Youtube videos, for example? Are you downloading torrents? What kind of internet connection is it?
...these are just starting points.
I purchased my MacBook in May 2009 - my OS 10.5.8
HD = 148.73GB with 66.76GB available
Model Name:MacBook
Model Identifier:MacBook5,1
Processor Name:Intel Core 2 Duo
Processor Speed:2 GHz
Number Of Processors:1
Total Number Of Cores:2
L2 Cache:3 MB
Memory:2 GB
Bus Speed:1.07 GHz
Boot ROM Version:MB51.007D.B03
SMC Version (system):1.40f2
My room mate and I use the network for the same eg Video, text, live streaming of news, sport, movies etc etc. Not downloading torrents. The connection is through Comcast Business
As well as the information requested already....
Do you tend to add "extensions" and what-not to the OS and to Safari? i.e. little programs to make Finder and Safari do more things? If you do, some of them can really bog down the system.
Look at activity monitor, and check the CPU - sort by CPU when the system is bogging down. Is there a process hogging the CPU? Also check the Memory tab when the system is bogging down. For what you need to check, Wired and Active are the same thing - are they using up virtually all RAM? Free and Inactive, again just for the moment are the same thing, should be showing more than a sliver. You can sort the monitor by Real Memory to see what is hogging memory, if you think something is.
Start with these, and report back.
Incidentally, when starting a thread you might get more responses if the thread title was more specific. "Multiple Mac problems" can be interpreted several different ways, and people who respond to calls for help are usually looking for problems that they know something about. So - "Mac Book slows down surfing the internet" will attract the interest of people who are interested in Safari and Network problems. As opposed to people who think you have a problem with too many Macs.
See my response re my system specifications. I no longer use Safari as it is impossibly slow even with the latest update - I have deleted all extensions including Growl already. I use Chrome. I use QuickSilver
Point taken about thread title.
I dont know what you mean by CPU hogger but Chrome and Chrome Flash plugin is taking up quite a bit of memory 130 - 288 Mb respectively.
Free is green 189MB and Wired is 266MB Used is 1.56GB
The above figures are during a relative optimum period. I will check these again when the system becomes impossible. For example yesterday I was trying to download an album from Itunes and it repeatedly stopped the downloads. This now happens all the time whereas previously I did not have this problem.
Thank you
