2012 iMac OS 10.8.3 Wifi dropping
Hey all,
I've been having this problem for a few days now and it's becoming more and more frequent so now I'm really struggling to find help anywhere.
Basically after a while for no apparent reason my WiFi will stop working with the error message "DNS Server not responding" or something like that, and all my internet activity ceases. Turning off and turning back on the WiFi solves the problem temporarily but doesn't fix it completly. I'm using a Belkin N+ Wireless Router and a Virgin Superhub in Modem mode.
When my internet connection drops I cannot ping my router and I cannot ping google.com.
Here's what I have tried so far:
Renew DHCP Lease
Rebooting Router
SMC Reset
Rebooting computer
Virus Scan (Don't ask why)
Uninstall Hamachi
Replace Mackeeper with Avast
Software Updates
Jigging the network settings (proper service list order, adding a new location all that stuff)
A couple of ideas I'd like to try but I'm not sure about:
Changing the DNS on my iMac
Changing the DNS on my router
Seeing if the connection works on my Bootcamp partition.
That's really everything I know, I know that when this happens no-one else on the network experiences any problem at all. Up until this started happening this had never happened before, I hadn't installed any new software and I didn't do any updates when this started happening everything installed and uninstalled happened after this started happening
This is really frustrating and it's making my work alot harder any help would be appreciated
Thanks,
- Mr G
