Internet very slow

Hi all,

Something weird and very annoying is happening to my new iMac,

For some reason Safari is incredibly slow , most of the time is doesnt work at all , tried using Google Chrome which is also stuck most of the time.

An old iMac G5 which sits next to my new iMac and uses the same wifi connection does however work fine , I´ve checked and they use the same DNS servers.

Same with iPhone 5 and iPad , they all work fine on my wifi network.

Anybody out there with suggestions?

iMac, Mac OS X (10.7.5)

How are you connected - wifi or ethernet? If wifi, is it an option to temporarily connect via ethernet to assist troubleshooting?

Ok , I just went out and bought a cable to temporarily connect and now all seems to be working well!

Thanks for that Paul ,

I might just drill a hole through my office wall and leave the ethernet cable in place.

Still puzzled why my old iMac works fine with safari on the wifi and why the new iMac´s Safari suddenly refused to work!

Cheers,

Yves

If you want to want to try to resolve the wifi issue you may want to try the following. No guarantee that it'll fix things, but the suggestions have helped some users with connection issues.

Add these OpenDNS settings in Network preferences (make a note of the number that is currently in your settings in case you want to revert):

http://use.opendns.com/#mac and then test.

Some on here don't advocate using OpenDNS, many others do. I use them myself. More info on OpenDNS:

Add a new Network Location (following instructions under 'Making New Locations':

This second suggestion has worked for me in the past.

Have an appointment at the Genius Bar tomorrow. It just seems like more and more things going on. I was burning a disc last night and what usually takes 20 minutes instead after 2 hours received an error message that The Drive reported an error then tried again and another Mac OS error popped up.

Was on the phone with support last night and in going over everything I have done up to this point. First having cable company check the service which was ok. Buying a new wireless router(didnt help). Talking with support.

Support said it could be both Optical Drive and Processor. Also not happy about the dust particles behind the screen. Computer is about 60 days old and first Apple/Mac product I have ever had issues with.
