Hi! I have a problem I need help with:

Basically, the internet on my MacBook Pro drops out randomly throughout the day while I'm using it (usually in the evenings). Sometimes (if I'm lucky), a simple restart of the laptop fixes the problem, or sometimes just waiting a couple of minutes is enough and the internet reconnects itself, though often I'm just left frustrated and internet-less until I get my boyfriend to take a look at things, and occasionally he's fiddled with our router's settings and that fixes it temporarily (like for a couple of hours).

Sometimes I'll turn the laptop on, and there'll be no bars on my WiFi signal symbol. Sometimes I'll turn it on, and there'll be full bars but no internet (no pages load even though it says I'm connected, or sometimes I'll turn it on and everything will be running smoothly (before it cuts out eventually as I'm using it). Sometimes I'll turn it on and our Wireless internet network won't even be there as an option to join!

Now! An important note: this only happens when we're at home, at the uni dorm my internet runs the same way (wireless with a router) and my internet is perfectly fine!

So, many of you may say that it's not my laptop that's the problem, but rather it's the internet/modem/router here at home. Only thing is, that my boyfriend's laptop (a Toshiba)'s internet (also Wireless) runs perfectly smoothly and never cuts out.

So I was wondering if any of you had any ideas as to why my WiFi has problems only here at home? Do you really think it's a problem with the modem/internet itself? Because we've replaced the router with a brand new (Belkin) one and it still has problems! And why is it, then, that my bf's laptop's wireless has no problems?

Sorry if the explanation of my problem's unclear, I find it hard to explain things, but if any of you have any questions about it please ask and I'll answer to the best of my ability!

I'm having the same problem, so if anybody knows the issue here, I'd appreciate some feedback.
Some elaboration on my situation-- I'm having all the same issues, including that my roommates' PC computers are connecting without any trouble. We installed a new router, which seemed to work for a day or two before getting patchy again. Then we tried signing into the router and manually adding my laptop's MAC address, but I'm still having the same patchy wireless, even though my airport icon shows full reception. Any ideas? Thanks!

I am thinking it may have to do with your wireless settings. Double check them under system preferences<network. It should show your server then check out the details and report them back here.
If you guys could also please post your specs it may be very helpful.

I don't know if that's what you meant but I'd say everything is there!
