    Change your router channel.  Sometimes this is all you will have to do.

     

    Power cycling the router.  Read the router's user manual or contact their tech support for instructions.

    Okay Guys,

     

    I might have a solution to this issue.

     

    I would be browsing the net or downloading a file and then my internet seems to stop working. I check my WiFi connection and it is fine, but no internet!!! Its as if my WiFi still works but the internet part doesn't connect. My other machines seem fine, except my Mac.

     

    My MacBook Pro is a few months old and I haven't changed much. After looking around I found some YouTube clips that say you must change the DNS settings to 4.2.2.1 and 4.2.2.2. This also speeds up the YouTube clips quite a bit.

     

    Go to System Preferences -> Network. Make sure your Location is set to "Automatic". Choose the network name, then click on the Advanced button at the bottom. Select DNS and remove any settings there may be. Then add the two setttings I mentioned above. When you are done choose APPLY.

     

    After I did this the network seemed faster but the stability issues came back. That got me thinking, and I realised my MAC worked perfectly until about two or three weeks ago. So what could have changed in the meanwhile? Then I realised that the only changes on the machine I made was with the "Time Machine" settings.

    I never used Time Machine until about two weeks ago. After I switched on the Time Machine that is when my internet troubles started. This sounds funny, I know!!!!! I switched off my Time Machine and the internet connection has been perfect. No connection loss at all.!!!!!

     

    I'm not a MAC guru but i have many years in systems development and I understand the concept of bugs in a system. I think that there might just be a setting in Time Machine that is causing trouble with the WiFi internet connection. Try switching off your time machine and only switching it on when you want to do a back-up. So far it is working for me. Wierd but true :-) This might end up on Ripley's Believe it or not.

     

    I hope this helps.

     

    Cheers,

    Julian
