Q: Macmini suddenly lost Internet but connected to router

My Mac mini v10.7.5 stopped working on the Internet over night? Safari doesn't work, AppStore or anything. Downloaded Firefox from separate computer and installed it, says no Internet connection although my computer was connected to my router, all connection setting said connected fine, I could log into my router and see my mac connected. I removed all locations from network connections, made new ones, still no luck. This is through Ethernet . Tried my wifi and that does same. I tried deleting some other files from the library folder which I saw on Internet. Something like preferences plaits or something. I then tried replacing my com.apple.mDNSResponder.plist and ....helper.plist files with working apple ones with no prevail. Now I'm struggling to connect to my router it's giving me a incorrect ip, so I've manually set it but its now failing on Internet and server on the network diagnostics. Which is wasn't before. Hellllllllllp please

 

Ps my iPad, iPhones, windows laptop all work on the router, so it's not a router problem. I've also took it to another persons network which is working fine and have the same problem.

Mac mini, Mac OS X (10.7.5)

    Hello,

     

    In a browser's URL bar, put this & hit enter, does that get you to Apple?

    Have you done a PRAM reset, CMD+Option+p+r...

    In fact, do 3 in a row, takes a bit of time.

     

    How many devices are connected to your Router?

     

    Though all of these steps may or may not be needed, I'm including them all.

     

    Make a New Location, Using network locations in Mac OS X ...

     

    http://support.apple.com/kb/HT2712

     

    10.5, 10.6, 10.7 & 10.8…

     

    System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

     

     

    10.5.x/10.6.x/10.7.x instructions...

     

    System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

     

    The interface that connects to the Internet should be dragged to the top of the list.

     

    If using Wifi/Airport...

     

    Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

     

    For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

     

    208.67.222.222

    208.67.220.220

     

    (There may be better or faster DNS numbers in your area, but these should be a good test).

    Click OK.

    Please read this whole message before doing anything.

    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.

     

    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
       
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.

    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

     

    Test while in safe mode. Same problem?

     

    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

    hi thanks to both of you i solved my problem. booted in safe mode, then added the dns from the first poster. it connected up. rebooted in normal mode and it wouldn't work. I deleted peerguardian, from preferences, users and groups, login in items, then deleyted the program and any instance i could find of it. Restarted and it worked a treat, not sure whats gone on there, i have had that on and used it for over a year.

     

    anyway, thanks guys, really appreciate your help

    DNS has nothing to do with the problem. I suggest you revert your DNS settings to what they were unless you have a reason to use OpenDNS, which you almost certainly don't.
