Hi. I am a completely new Mac user (just bought a new MBP today-- OSX is 10.6) and I have absolutely no idea how to get the wifi going.

I chose the network I'm trying to connect to and put in the password. The signal is full (as it should be, I'm right next to the router!) but I can't connect to the internet. I looked through the network preferences and Airport says "No IP Address". No clue what's that about. Can anyone please lend a hand?

Some more info:

- Using DHCP and did try renewing the DHCP lease to no avail
- Router is a WRT54G

I'm not sure what else needs to be said, but if there's anymore info necessary let me know! I'm just getting extremely frustrated as it's been a few hours now that I've been trying to solve the problem.

Also, this isn't going to be a problem when I bring this to the uni campus will it?

So you can get online with the WRT54G connected to the MBP with an ethernet lead.
Has anyone else been able to connect to the wireless network - have you been into the Admin page to set it up?

Have you been into Sys Prefs > Network > Airport > Advanced > TCP/IP to make sure Configure IPv4 is set to 'Using DHCP' and if you select header alongside TCP/IP namely; Airport - does that show the name of the wireless Network?

You know I thought I had figured this out but it's f'd all over again.

My internet is fine. The other Windows computers in the house are connected (such as the one I'm using right now), it's just my Mac. Also, yes-- Airport is recognizing the wifi and the signal is full like in the picture, but it just doesn't connect to the internet. Thus the "No IP Address".

And yep, I've checked and double checked the settings on the Sys Prefs. Also restarted my router twice! I just don't understand what's causing this.

If you connect to the router using a windows machine, can you see on the router that your Mac has a wireless connection with the router.
If you connect your Mac to the router using an Ethernet cable, does it work that way ?

I tried connecting the Ethernet directly to the Mac, but it comes out the same. It's either "No IP Address" or "Self-Assigned IP". Which drives me nuts because when I put the ethernet cable back into one of my Windows pc's it works fine.

Also, no my Mac isn't showing up on the active client list.

I was going to ask what encryption you are using on your WRT54G Wireless but since even Wired does not get you an IP, it's probably something else. With some (especially newer) WRT54G's I have had issues with WPA encryption using AES. If I switched the router to TKIP, all worked fine.

If the Linksys is set to DHCP, the Mac plugged in should get an IP address almost instantly.

Collin_Bl: Yep, I made sure that was checked.

dtravis7: I did end up eventually getting an IP when I connected the ethernet directly, however then the problem became about "Network Settings".



I am at back at uni now and I have no problem connecting to the internet. So it looks like it's only in my parents' home that is having trouble. I just don't understand it.

Who did the initial set up of the Linksys - you? If it was someone else they may have enabled Access Control;

I did set up Linksys-- I hope that's not not why I'm having trouble connecting, haha!

I'm not sure where to get the Access Control... is that the same as MAC Filter? Because I have disabled that.

I'm also back at my parents' now, have reset the router again and still no luck.

My AG310 has UPnP under Admin>Management - have a hunt for yours and make sure it is enabled. If that makes not difference then with both Wireless and Ethernet giving you trouble time to go thru all the settings in Sys Prefs > Network > Airport and/or Ethernet to try and find the common factor.
