Q: Rejecting Correct Network password

recently upgraded my wifi router, and since then have noticed that the laptop is struggling to connect to the network.

 

It sees the router (as well as several others in the neighbourhood), yet when i try to access Internet, it get error messages telling me my password is wrong. It is not wrong!  I have several other devices all of which can access using the exact same password.

 

Eventually after many attempts it will finally recognise the password, and will work fine for the rest of the day.

 

Next day, the problems start over.

 

I have tried to erase the previous log-in settings from the Network Prefs, and have created new location and settings. Same result.

Also noticed that the Battery icon is showing "Service Battery" - i'm not sure if this would have an effect on the macs ability to remember its network settings - however, the mac is always connected to the mains anyway.

 

 

The macbook pro is a 2.8ghz Corei7, with 8gb ram and running 10.9.4.

 

any suggestions what might be wrong?

 

thanks

MacBook Pro, OS X Mavericks (10.9.4)

    Hi Lightningad,

     

    My understanding is that you are having issues with signing in to your Wi-Fi network, with a password that you know is correct because it works with other devices. Further, you have an issue with your MacBook Pro's battery, which is showing you a "Service Battery" error, and you are concerned that this may be contributing to the difficulty signing in to the Wi-Fi network. Is that correct?

     

    Let's start with the second question, concerning the battery. Since the computer seems to function the same using AC power, the battery issue is not affecting your Wi-Fi. The battery should, however, be replaced. As this will require opening up the MacBook Pro, it will need to be done by Apple or an Apple authorized service provider. this page has information about service for the computer and battery replacement - Apple - Support - Service Answer Center. Note that if you are not in the United States, you will need to change the country once you get to the page.

     

    One resource I would suggest to you for making sure your router will work well with your MacBook Pro is this - Recommended settings for Wi-Fi routers and access points.

     

    This page will also help you with your issues connecting to the network - Use Wireless Diagnostics to help you resolve Wi-Fi issues on your Mac.

     

    If these do not resolve the issue, continue.

     

    I am not certain what you mean by having "upgraded your wifi router." This could mean the purchase of a new router, changing the settings on the same router, or installng new firmware on it. For the first two, we can test for where the issue lies by putting the original router, or returning the original settings to the router and testing whether this issue still occurs.

     

    Since it is typically impossible to downgrade firmware on a router, if this is what you upgraded you can't go back to test. A different strategy would be to test your MacBook Pro on a different Wi-Fi network. Perhaps one of those neighbors whose networks you can see will allow you to connect and test, or a local coffee shop or library. Even better would be to test this with the Wi-Fi network at an Apple Store, if such is available.

     

    If the same issue occurs with the old router/settings or on a different network, we will have isolated the issue to the computer, and can work with that. If, on the other hand, the situation changes when working with a differnt network, you will need to consult with the maker of your router for guidance.

     

    Thanks for using Apple Support Communities.

     

    Sincerely.
