Re: How to fix Wi-fi Connection Timeout Error on iMac OS X Lion
I have found that there are many people who are having such issue after upgrading to Mac OS X Lion. Many say that Mac OS X Lion is more sensitive as compared to Snow Leopard when wireless networking is concerned but I dint think its that. The cause of this issue is mostly wireless cards, wireless cards, routers or the combination of these two but you can try out the below workaround to find out the same.
- You can start with Basic WiFi Troubleshooting like Turn wireless on & off, rebooting the Mac or Resetting the Router but if they are not making any difference in your case then you can proceed with the Advanced WiFi Troubleshooting methods.
- The Advanced WiFi Troubleshooting includes setting up a manual IP address with DHCP, moving Wi-Fi to the top of the Service Order list, moving the router to the top of “Preferred Networks” list, deleting the existing WiFi connections and adding them again, adding an extra DNS entry, adding a New Network Location and so. You can go through the same in detail.
- Setting up a manual IP address with DHCP- Go in to Network > Advanced > TCP/IP settings and use “DHCP with manual IP address”. Here you should Pick an IP which is in close range of the router.
- Moving Wi-Fi to the top of the Service Order list- Here one has to prioritize WiFi as the primary method so that the system connects to the internet maintaining the connection.
- Moving the router to the top of “Preferred Networks” list- You can access the “Preferred Networks” list by going in to “Advanced” menu in Network settings, you just have to Drag your primary router to the top.
- Deleting the existing WiFi connections and adding them again- You have to click on the ‘minus’ icon for removing the existing WiFi connections and then click on the “+” for adding it back to the WI-Fi connection.
- Adding an extra DNS entry- I am not sure about this but I have found a number of users mentioning that adding an extra DNS entry adding 184.108.40.206 which is Google’s public DNS to the list has helped them out.
- Adding a New Network Location- Go in to the Network control pane and check out the ‘Location’ menu and move down to ‘Edit Locations’ and click on + sign for adding a new network Location, after renaming the same click on ok and select that “Network Name” and click on apply.
Hope that helps.
