Q: When is Apple going to provide an update to Mt. Lion which fixes the glitches relating to the fact it drops the internet connections every time I put my computer to sleep?  I've taken the machine to the "Genius" bar and no fix was provided.

What did they tell you then?

Not everyone is experiencing these glitches.  Me included.

Please detail ALL you have done so far in the way of troubleshooting prior to taking your comp to the repair shop?   Need this info to avoid the been there done that scenarios.

Do you have the latest update for Mountain Lion 10.8.3 (Build 12D78)?  Run the Software Update option to check.

Then you can check the wifi to see for signal strength and competing neighbours using the same channel etc by holding the Opt key and selecting the wifi icon. Select Wifi Diagnostics.

Then select View in the menu bar and Wifi Scan

Some you may have already tried:

Try the basics first:

   Change your router channel number.  Most times this works & is all you have to do.

Disconnect & reconnect your modem.  unplug it for about 10 seconds.  Plug it back in.  Do the same for Apple’s routers.  Wait for everything to reboot.

System Preferences>Network

Click the Assist Me button.

In the next window that pops up, click the Diagnostic button & do the necessary.

If using Apple's Airport, please re-post over in one of the AirPort Forums.

I told the apple employees exactly what is going on. That is every time I put my desktop to sleep and reopen it, I must go through the Network Diagnostics routine in order to access my wireless connection to the internet.

 

I have read of a number of people who upgraded from Snow Leopard to Mt. Lion experiencing the same problem. I followed a suggested fix in one of the user forums.  This consisted of: entering system preferences, choosing the network icon, pulling down "edit locations", adding a new location and giving it a name and clicking done. The machine responds by returning to the Network screen. I then clicked Network Name menu and "join wireless network".  According to the instructions  that should have fixed the problem.

 

They suggested that, if it did not, I should renew the DHCP lease via the Sys Pref, Network, Advanced, TCP/IP Tab and verifying that the IPv4 was set to "Using DHCP". Then I was told to click on "Renew DHCP Lease" and to click apply when prompted. It was also suggested that I reset the MTU size to 1453.

 

I did all of that twice before taking my desktop to the Genius bar.  The Apple employee rushed through various menus and pull-downs, etc. and announced that the problem was resolved. I tried to get him to explain what he had done but could understand about half of what he said. I took the machine home and turned it on and the exact same problem occurred.

 

I have even read on line that some users who upgraded from Snow Leopard are so dissatisfied that they are looking for ways to "deinstall" Mt. Lion.  I don't want to do that. I just want this "glitch" fixed.

 

Any suggestions would be welcome. Thanks.

You should have taken the comp right back to the repair shop.  Matter of fact, suggest that you do so.

When it’s time to pick up your computer from the repair shop:

*** Before you leave the repair shop, make sure you have the repair tech(s) power the comp up and demonstrate that it is indeed working & repaired properly to your satisfaction.***
