So I've been having a lot of problems connecting to the internet on my MacBook. I have the base model, OSX 10.4.10. I got in in July 2006, so just over a year old. So, the first problem I had was last year, I had no problems connecting through the ethernet cable in my dorm room, but it wouldn't work in other people's rooms. Everything else was fine though. Wireless was perfect. This summer, I went home and I used the wireless in my room with no problems for the first few weeks. Then all of a sudden it stopped working in there. I had to be sitting 10 feet from the router for it to work at all. It only had 3/4 bars of signal strength at that distance. I tried connecting with the ethernet cable, and the computer didn't recognize it. I called up my ISP and they walked me through a bunch of stuff that didn't fix it. They said that there seems to be a problem between Mac and 2wire routers. Weird because it worked perfectly before. Now, I'm back at school and it's still not working. I took it to the Mac store, and it had trouble with one of their wireless networks, but the other was perfectly fine. It still didn't recognize the ethernet cable at the store. I got my computer to connect wired once to the school network, but it dropped it pretty quickly. I took it to resnet (the school's network/computer thing), they adjusted some settings. Wireless, still not working. Ethernet worked there, but not in my apartment. So, I'm really starting to think it's a hardware problem, but I don't know. Every one I talk to says the ethernet and wireless shouldn't both be affected if it is. I really need to fix this since I need internet for my schoolwork. I'd consider opening it up if maybe something's loose or needs to be replaced. I've never opened up a Mac though, so I'm a bit nervous to totally screw it up. Any help would be greatly appreciated. Obviously, with my lack of internet, I may not be able to respond right away, but I'll be checking back as often as I can.
