I just joined this forum to see if anyone has experienced this problem with MacBooks or any other Macs?
My wife and I purchased a new Macbook 2 weeks ago from apple. My wireless network I use at home is a airport extreme base station 802.11a/b/g/n, and has been in use for 5 months. I use two older PowerBook G4's with this wireless system. I have not experienced any connection problems using the PowerBook's with safari as the browser.
When we received the new MacBook immediately we noticed it having a difficulty connecting to the internet even with full reception on either safari or fire fox as the browsers. I called Apple Support for there help. During the first call we tried creating a new user, going into libraries and taking out the apple.safari.plist, and running disk utility. After that the problem seemed to be fixed, safari was up and running....only for about an hour though.
On my second call, Apple support suggested doing a complete power cycle with the base station, router, and Mackbook. Then we reset safari, and the PRAM. This seemed to solve the problem, and safari was up and running.... only another hour or so.
On the third call we emptied the airport card cache by holding down the shift key on power up. This didn't work so I was transfered to a wireless specialist. The first thing the wireless specialist asked me was, what type of wireless phone I was using. I told him 2.4ghz cordless, and he said that was the problem. I asked him why I wasn't having problems with my PowerBooks, and he said I was lucky. I gave him my cell number, he called me back on my cell and we unplugged the cordless phone base. The problem was still there. He told me that by protocol he had to transfer me to a product specialist.
The product specialist asked me to go to my airport signal bar in the top right of my screen. When I opened this it showed eight different wireless networks, but they were dropping off and adding on new ones every 10 seconds. The product specialist asked me to try and join one of the open networks, but my computer couldn't join. When I tried to join one of the secure networks it wouldn't even prompt me for a password. The product specialist said "we have been looking for these computers". Just like that, and then said we will send you a new macbook with a extra gig of ram for your troubles! WOW! That was easy!
The reason I am posting with so much info is because maybe some of you out there are experiencing the same issues, and just haven't talked to the right person to solve the problem.
Has anyone else heard of this issue, or what it could be?
