Q: router disconnecting when imac shuts down

I am on Mac OS  10.10.4   I have been using a Netgear router for about three years with no problems and have three devices attached, iPhone, iPad, And iMac.  A few days ago when starting up the iMac in the morning there is no connection to the network. To connect I have to unplug the electrical line to the router and then reconnect it.  the disconnect  also happen when I put the iMac to sleep.  I have not changed any of the setting in the network configuration.  Is this a bad router or am I overlooking something.

I am using a Netgear 300 wireless router model WNR2000v3

Netgear is no help at all involving this

Thanks

Dan

    Please test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.

    1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved. Make sure the box marked

              Remember networks this computer has joined

    is checked.

    2. Follow the instructions in this support article under the heading

              Symptom: After restarting or waking from sleep, my computer might not connect to the Internet

    3. Reset the PRAM.

    4. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.

    5. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.

    6. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.

    7. Repair permissions on the startup volume.

    8. Turn off Bluetooth and test.

    9. Reset the System Management Controller.

    10. This step shouldn't be necessary, but has been advised by Apple Support in some cases, apparently as a workaround for a bug. Open the Energy Saver pane in System Preferences. If applicable, click the padlock icon in the lower left corner to unlock the settings. Enter your administrator login password when prompted.

    Select the Power Adapter tab and uncheck the boxes marked

              Wake for Wi-Fi network access

    and

              Enable Power Nap...

    if present. Then, if the computer is a MacBook, select the Battery tab and uncheck

              Enable Power Nap...

    11. Reinstall OS X.

    Thank You.  I believe the problem has been solved by following your instruction.  I now have several networks in the drop down window  Where you create networks.  How do I delete the unused ones?

    You can't delete them. They are other networks in your vicinity. Just ignore them.

    I don't understand what you mean. How did you create these networks?

    Several years ago I tried several times to create a network for my airport express.  I used to to play iTunes thru a couple of stereos.  I also have 4 Netgear networks .  On;y one of them is operational.  the other three were created trying to get  the wireless hub to work when I originally bought it.  I created them using the create networks option

    Netgear29 is the operational network for my iPad and iPhone.  Dan's wi-Fi network was setup for  the airport music network, I don't use this at all anymore.   e  Charter is my internet provider but I do not know what these 4 charter networks are for.

    None of those is an ad-hoc network. They are all external to the computer and some may belong to your neighbors.
