So this is a problem I've been having for about a month now and it's only exclusive to the macs in my house. (two of my sisters and myself have macbooks while everyone else uses PCs) It's quite a peculiar problem that we have. For some weird reason the internet does not work with the macbooks. All the macbooks can connect to the router and when I ping the individual IPs of each macbook there are 0 packets lost. It's quite frustrating because usually when this happens at the wireless network at school, I can just turn off the airport and wait 30 seconds and it will work. Now here's the part that really gets me: the problem is exclusive to the day. For some reason at night time, the internet works for the macbooks. It has caused me to excessively use my macbook at night due to the lost internet usage during the day. It's been bothering my sisters and me for a while. I've gone to the apple store and they say it's because the fios router has a WEP security system and need to be updated to WPA2. I've done that and I still have the same problem. If someone has had the same problem please help me out. I searched the forums first before I posted this and found nothing like the problem I've been having. Please help...I need some ideas to approach this issue.
