Hello,
I realise that there are a lots of problems with Lion and WiFi, but unfortunately I haven't been able to locate a resolution to my particular problem.
I am on an iMac (2009, i5). Until a couple of days ago I have been running 10.7.3, upgraded from a 10.6 installation. Everything was working fine.
Due to a couple of issues I decided that it is best to erase the disk and make a clean install, this time from a 10.7 boot disk.
The installation went fine but ever since I cannot connect to my router using WiFI. I can connect to the router and internet via Ethernet and cable without any issues.
As far as the WiFi goes, the iMac can connect to the router, that's fine, but there is an exclamation mark in the wireless icon and the "alert: no internet" message.
I can only get self-assigned Ip addresses, and no connection. Entering internet settings (IP, subnet, router...) as they should be manually does not work. Renewing DHCP lease does not work.
I have upgraded to 10.7.3 from the clean install and also installed the WiFi upgrade - without success. I have tried deleting preferences (airport...) without success.
I do have a macbook pro sitting next to the iMac, running 10.7.3 (upgraded from 10.6) connecting to the very same router without problem. A router problem is thus improbable.
Is there any known fix to handle the issue? What are my options? Do a clean install of 10.6 and then install 10.7 over it?
thanks in advance
