Wifi problems seem to crop up a lot on here and unfortunately there's never a 'one fix' solution.
However, I have seen that sometimes any one of the following can help some users although, unfortunately, not always. A bit hit and miss I'm afraid - and in no particular order:
- Check wifi security - if it's WEP change it to WPA or WPA2 (preferably, as it's more secure)
- Add OpenDNS numbers to your network settings as described here: http://use.opendns.com/#mac
- Change the wifi channel on the router
- Create a new Network Location: http://support.apple.com/kb/HT5289
- Reboot the router
I have tried differnt channels, the security is wpa/wpa2 etc, etc but the same problem still happens. The only thing I have not done is the DNS numbers because I don't understand what they are.
Thanks for your help.
Some don't advocate using either OpenDNS or Google DNS numbers, but many others do.
I happily use OpenDNS.
What kind of router is it? Some of them are dual band but not simultaneous. This along with other wifi things in the home can recreate weird situation where it looks like your connected but you're not. If you can go into your router setup and lock the band to 2.4Ghz and your weirdness go away, this could be your problem.
Since using the open DNS everything seems to be fine, I have had no boxes come up telling me 'server not found"
I think the problem has been solved - thanks very much guys really appreciate your help.
