Wi-fi self assigned IP

Go to System Preferences > Network > the WiFi symbol > make sure lock is open > Advanced > TCP/IP and have it go to DHCP instead of fixed.

reset your wifi router and try again, most issues with wifi really require a reset at both ends not just at the device end.

How is your modem/router setup? Does it broadcast the name of the network and does it assign IP addresses? If so, then you should be setup to Configure IPv4 using DHCP. Using a fixed IP address will cause a conflict with the router.

The self assigned means it is not picking up the IP address from the router.

In that Network, WiFi, Advnaced, TCP/IP window you should see an IP address for the router, and an IPv4 address, the router address usually ends in a 1, and the IPv4 address matches except for the fnal number.

What sequence are you seeing but don't give the exact number sequence use x's excecpt for the last number if all the other numbers are the same.

When you restart the computer that will then get a new IP address or renew the lease on the address it has been using...that may be enough to keep the router happy.

Enjoy and Happy New Year.

If you have a problem with the WiFi conenction telling about the self assigned IP, then go to your router's setting and turn off the 802.11 n-mode.

That helped me after several hours of trying around with all possible static IPs and such.

I don't know if it is relevant in your situation, but maybe somebody else will read it

hello i have the same issue of self assigned ip but i have probably tried everything possible. is the problem with my mac? or is it with my internet provider?

btw forgot to mention i am able to connect everywhere at wrok etc.. but my house

I posted already something that actually solved the problem on all macs connecting to routers with the same problem. Just change the Encryption Algorithm from TKIP to AES. Well there are differences and Apple computers seem not to be a big fan of TKIP. It works for some people but it creates more conflicts. The other thing I changed was the Group Key Interval from 900 to 3200.

All changes were made on the router.

It's working on every computer with this problem.

Hi Orpheusmyth just read your response to self assigned ip address, could you explain how you change the encryption algorithm and group key interval as i don't know how to do this

I have a simlar problem.

I have 2 mac minis for my kids and 2 x imac, 1 x macbook air.

My network uses airport extreme's gen 3 I think.

The network has been in place for over a year with no problems, and the minis have been functioning well for 6 months or more.

In the past 6 weeks both of the mac minis have been self assigning the ip address. I've deleted the network settings and started again from scratch several times. and once or twice powercycling everything (cable modem, minis, airports) has reconnected. but eventually the ip is self assigned. I'm installing Lion to see if it makes any difference. I can drop and reconnect iphones and ipads sitting next to the minis and cannot reproduce the problem on anything but the 2 minis.

Hey Keith, still having problems?

What router do you have? Sorry for the really really late response but well only got it now, not sure why.
