I have an apple airport express, that is plugged into a modem provided by comcast. I've just been unplugging the ethernet cable from the airport and plugging it into my macbook. The cable works fine when it's used with the airport, so I don't think that's the problem.
My modem doesn't have a light labeled "link", but there is one for "PC". The PC light blinks when it is plugged into the airport, is off when it's unplugged, and blinks again when plugged into my macbook.
So you think this is a problem with my modem? With every other laptop I've owned, I just plugged the ethernet cable in, waited a few seconds, then started browsing. Are there no settings on the laptop to get an IP assigned?
Thanks for you help,and sorry if these seems like a dumb issue.
Doubtful that it is the modem.
Have you tried to "Renew DHCP Lease"?
Open Sys prefs/Network select eh Ethernet the advanced once in the advanced menu make sure you are under the TCP/IP tab and press the "Renew DHCP Lease" button.
If this doesn't work then still under advanced select eh Ethernet tab then make sure that configure is set to Automatically.
If still a no go try resetting the modem by unplugging it for about 10-seconds then perform the Release again.
I will have to ask though what are the problems that you're experiencing with your ISP or network in the first place?
Thanks. I'm not home right now, but I'll give that a shot later.
About 3 weeks ago, my internet connection slowed down dramatically. Normally I get about 10mbps, but it dropped to under 1mbps. And it dropped the connection entirely every now and then. A tech looked at it today and replaced the modem, which seems to have fixed that problem. But even with the new modem, I still can't connect using ethernet, only through wifi.
ahhh ok... if the release and renew suggestions above don't work try powering the cable modem down and then backup after you plug it into the macbook. cable modems tend to lock to the MAC address of whatever device is connected to them at powerup. if that works don't forget to power the cable modem down and backup when you reconnect it to the airport express.
i don't think its a problem with your modem persay... i think its differences in the way macos asks for an ip from the modem... are the other laptops you are refering to running another operating system?
if you really want to use wired consider getting an airport extreme base station (or even a cheapo linksys etc) ... they have the wifi and LAN ethernet ports... that way you can connect wired and wireless through the same device (and at the same time)!
