E6420 research thread

Go to open network preference -> turn wifi off -> turn wifi on

and then try to connect again. May have to try a few times or reboot again to work successfully.

I have tried it many times with no rersult.

 

First I get:Wi-Fi does not have an IP address and cannot connect to the Internet.

 

And then>

 

Wi-Fi has the self-assigned IP address 169.254.140.11 and will not be able to connect to the Internet.

 

Anyu ideas?

That's really the last thing I neen to solve.

 

Thanks

have you tried just deleting all networks, apply settings, then add them back?

Thanks,

 

"apply settings"

 

What do you mean by that?

 

Thanks

[Bronxteck]

well when you delete the network settings there is a button that says apply. do that before re adding the network

I tried many times with no result, it's not getting IP from common APs (tried on Apple Airport too).

The only AP that works is tethering AP on my Android phone (Desize Z or G2, CM7, a 2.3.7).

Hello,

 

For the owners of a Dell E6420 with the intel HD 3000 only. I've just managed to get the LCD display to work at native resolution in 10.7.2 by adding the DualLink patch. The driver still hangs every now and then but at least it's a start. HDMI out also seems to be working fine.

 

I have attached the patched DSDT file just in case someone wishes to test it .

 

Display override for the internal LCD display also attached with my EDID.

 

Br,

[*]Have fun.

 

First of all thank you for documenting the E6420 OS X installation.

 

I have a near clone of your E6420 which I followed the general outline of your guide and installed OS X 10.7.4 ; I changed out the stock Wi-Fi card for a AR5B95 card a chased around to find a kext that would get me on line with WPA2.

 

My main problems are "Restart" hangs with the power mostly off and never cycles back; I have to hold the power button down to get the machine to power down. Shutdown does work.

 

And then sleep does not work.

 

Of special interest is that VMWare Fusion 4.n runs and I have XP Pro and Windows 7 virtual machines running concurrently. And the VMs can get to the internet through the Wi-Fi connection.

I have the Intel HD 3000 in my e6520! Can you please post in the e6520 section a tutorial for what you did at least regarding that displaygetting full resolution. I've been trying nearly a year now. Thank you so much

Seriously! Finally someone with Intel HD 3000 has got it fully working! now how'd you do it and can you post under the e6520 thread. I seem to be the only one with that GPU but I'm sure others will soon show up. Thank you so much and I'm looking forward to your help.
