I'm a Mac, and I can't get on the internets.

Wireless internet conundrums. After internet signal problems being repaired by the internet provider and plugging into the modem directly showing that the connection itself is fine, the wireless goes out every few minutes for the Macs in the house, but works fine for the PC.

My roommate and I have cable internet that we run through a Belkin N wireless router (WPA2 Personal encryption or whatever it's called). The router is a couple of years old and has worked fine during all that time. Last week, we started having issues where the internet would work occasionally, but as soon as we tried doing anything bandwidth-heavy, like streaming video or uploading files, the internet would stop working entirely. Resetting the router didn't help. It would start working again randomly minutes or hours later. ISP sent out techs to fix the lines going to the house, said there had been an upstream signal problem, but it was fixed. However, we were still having problems. They came back out and found that there was damage to the lines at the pole itself, but that it was now fixed. It still wasn't working on my laptop, so they had me plug directly into the modem and run a speed test and try to max out the connection by opening tons of YT videos and running several speed tests at once, but everything still worked fine.
However, my roommate and I are still having problems with the wireless. We thought it was the router, but out of curiosity, I tried using the wireless on my old PC laptop and it works perfectly fine. It just doesn't work on our Macs (both MBPs, mine is a couple months old, hers a couple years). I'm able to use wireless anywhere else with no problem, so this is specific to our house.
Our connections go out every five to ten minutes. Turning Airport off and on again gets it working again, but only for a few minutes. Our outages are not always at the same time, like I'll be online and she won't then mine will go out and hers is fine. Another problem is that while it used to be that as soon as I opened my laptop from being asleep/opened a browser window, I was immediately online. Now, however, it takes longer to connect.
I went ahead and opened Network Preferences and timed what was going on when I connect and have a timeline: Turned airport on, it does the flash-type thing on the icon in the toolbar and says in Network Preferences "Not Connected: AirPort does not have an IP address and cannot connect to the Internet." It still says this after the icon is solid. Then, 30 seconds after turning Airport on, it says, "AirPort has the self-assigned IP address XXX.XXX.XXX.XXX [except with the actual numbers] and will not be able to connect to the Internet." About 1 minute later, it says "AirPort is connected to The Internet and has the IP address XXX.XXX.X.X [except with the actual numbers]." Then the internet works.
Then, when it stops working, usually after 3-10 minutes, it still shows the message that it's connected.
We can't figure out the mystery as to why our Macs won't connect properly to the internet while the PC is just fine. Everything worked fine before our internet outage last week. Does anyone have any suggestions as to what might be going on or what we can do to fix it?
Things I've tried: restarting the computer, deleting the network and re-adding it, renewing the DHCP lease. I'm not a total techie, but I'm pretty good at following directions and figuring out computer stuff when necessary. This is my first Mac, so I don't know if there is some special Mac thing I'm not realizing I need to do (my roommate can't think of anything, either).
