I have never experienced this problem before. I know that the problem is not the internet, because the internet works fine on all my other devices, both Windows and Mac. I brought my MacBook in to the Apple Store this morning and they renewed the DHCP and deleted the internet plist files from my system preferences library folder. They ran a hardware diagnostic and my hardware is fine. At the Apple Store, the problem was duplicated also when connected via ethernet cable to the network - so it's not an airport problem.
It's very strange because sometimes the internet works and sometimes it doesn't, so it's very hard to know if a fix works or not. Renewing the DCHP seemed to work at the Apple Store, so I brought it home, and now can't get back on the internet here. I re-renewed the DHCP, re-added my network, manually entered the DNS, rebooted, and still not working. AirPort shows it is connected to the internet, but when I attempt to load a website, it "thinks" for a long time without loading anything and then eventually gives me a "can't establish connection" error message.
My network settings are as follows:
In the main Network window: Status: Connected Network Name: ibahn AirPort is connected to ibahn and has the IP address 10.58.207.44. 802.1X: WPA: Awarenet
On the "Advanced" window:
AirPort tab: Network Name: ibahn Security: None "Remember networks this computer has joined" is selected, all other options not selected. AirPort ID: 10:9a:dd:bb:25:7b
TCP/IP tab: Configure IPv4: "Using DHCP" IPv4 Address: 10.58.207.44 Subnet Mask: 255.255.252.0 Router: 10.58.204.1 Configure IPv6: "Automatically"
DNS tab: DNS Servers: only one in the list - 10.58.207.44 nothing in "Search Domains" field
WINS tab: NetBIOS Name: MACBOOK-5BF526 and next to it it says "MACBOOK5BF526 is currently being used." Workgroup and WINS Servers fields are empty
802.1X tab: User Profiles: WPA: Awarenet Awarenet Profile (both of those are boxes that are checked) "WPA: Awarenet" : User Name - egoodwin; Password - ? (seems to be a password but I have no idea what it is); Authentication - PEAP, TTLS, and EAP-FAST are all enabled, TLS, LEAP and MD5 are disabled; Wireless Network: Awarenet; Security Type: WPA2 Enterprise "Awarenet Profile" User Name - egoodwin; Password - ? (seems to be a password but I have no idea what it is); Authentication - PEAP is enabled, TTLS, TLS, EAP-FAST, LEAP and MD5 are disabled; Wireless Network: Awarenet; Security Type: WPA Enterprise
Proxies tab: under "Select a protocol to configure" no options are selected/enabled
Ethernet tab: Ethernet ID: 10:9a:dd:bb:25:7b Configure: "Automatically" MTU: "Standard (1500)
Anyone have ANY idea what could be wrong? The Awarenet thing seems off, but I'm not sure what that's all about and what the default would be - so if anyone has suggestions or knows what's going wrong, please do tell me!
