I can connect only two devices (maximum) to the internet simultaneously via my home network. This limit first started happening two months ago, in August. Internet Service Provider: Time-Warner. Cable Modem: Motorola SB5101 SURFboard cable modem (not wireless). Wireless Router: Apple AirPort Extreme Base Station Model A1034 (2003). Devices: (1) iMac 2GHz Intel Core 2 Duo w 3Gb memory; (2) MacBook 2.16GHz Intel Core 2 Duo w 2Gb memory; (3) iPod Touch 3rd generation; (4) iPod Touch 4th generation. It seems like the problem started around the time (perhaps not exactly) I upgraded both computers to Mac OS 10.7 Lion. (Before that, all four devices worked on internet simultaneously.) Possible solutions?
