Fix for Mac not connecting to local network

Hi,
I'm a uni student and I've had trouble connecting my Macbook Pro to the local Uni network so I can access computers connected to the network from my computer in my dorm. It worked perfectly fine the first day and then it stopped working. I contacted Apple today to fix the problem and was told to the following procedure:
OS X Mavericks: Reset your computer’s PRAM
It solved the issue perfectly and I also found the reason for why my Mac was not connecting. Well since I've got a few more devices at home I've setup 'Internet Sharing' on the Mac so my ethernet connection is shared wireless through the computer's built in router. Turning this function on for some reason blocks you out from accessing your network. So yea, I thought this might help anyone else who've had the same problem, since I couldn't seem to find it anywhere on the internet!

Not on this forum. Classic Mac OS 9 is not the same as Mac OS X 10.9 Mavericks.

Not connecting to local network?

Hi
I just got back to uni and went to plug my laptop into the local network so I could get online. But it does not connect for some reason, whereas it was fine a few weeks ago. I looked at the Network settings under system preferences and they were exactly as they should be. Has anyone got any ideas? It can connect to wireless networks fine, are there a bunch of settings elsewhere that I could fiddle with?
Thanks

Try cutting the power to it, otherwise there should be a little reset button which you would need a paperclip to activate (you would hold it until you see the lights flash or do something unordinary). Weather or not you have this button depends on carrier, dsl or cable, combo box etc. If it's working on other computers, then that probably indicates that your computer is not getting the correct IP address (possibly the same from before you left for your trip). The box may have changed it automatically (as most do). After shutting down your computer, i would try the things listed above, then reboot. If you are still having problems it may not be a bad idea to call your cable/dsl company. I know when i have had these problems in the past they have been able to fix them when all else has failed.

Lync 2011 for MAC not connecting externally to On-Premise Lync 2013

Hello,
Hopefully someone has some idea on this or a better direction for me to follow. So currently I have an issue where Lync 2011 for MAC clients will not connect when external to my On-Premise Lync 2013 servers. Everything to do with my Windows based clients
and even cell phone based client’s works just fine. It is currently only Lync 2011 for MAC which will not correct externally.
I did initially have the logon problem internally as noted by other posts online when using an internal CA certificate with Lync. But with the internal certificate imported onto the MAC when internally connected Lync 2011 will login just fine. Now in my
setup I do have a TMG server that clients are connecting to that forwards the connections onto my Lync servers when connecting externally. When I review live real time logs to see what’s connecting to the external URL for Windows based clients I can see them
connect in on port 443 no problem.
But with the MAC I don’t see any attempt from it to connect to the URL like I see with the Windows clients. Now below is what shows up in the Microsoft-Lync.log generated by the MAC. Now initially looking at the log I thought my problem was the fact when
Lync 2011 tires to connect when external that it was doing so on port 5061 which we don’t have open. So I tired entering external.mydomain.com:443 in for my external server in the setup.
And while rechecking the log after doing so shows like it is now trying to connect on port 443. When reviewing TMG I again see no connection attempt by the MAC to connect to the Lync external url or on port 443. Further research so far into the problem has
come up empty on the subject. And most other cases where people report problems connecting externally they are using some form of online service like Office 365. So at this point I am not even sure if Lync 2011 for MAC is supposed to work externally with On-Premise
Lync 2013 deployments or not. If anyone has an thought’s or idea’s please share them as at this point I am stuck on this issue.

Hi Nicholas Sayewich,
I tested in my lab and without any problem.
I also use TMG as Reverse Proxy and without configuring SRV records (My ISP don’t support SRV), after importing the root certificate onto MacBook, I can sign into Lync everywhere(internal
and external).
Please make sure that the certificate is set up to
Always Trust .

Mac not connecting with PC network

I'm attempting to connect my Mac to a wireless internet network through a PC. The PC is connected through Qwest with a D-link router. The PC connection is working fine.
The Mac sees the network and requests a password. I type the password, but nothing happens.
I don't know what other information to provide here.
Thanks!

Welcome to the forums Lewis!
Try putting a dollar sign in front of the Password, and make sure its 5 or 13 digits if WEP.

Fix for iPod not connecting

I was having trouble with my iPod, it would show up in windows, and say 'iPod Service Error ' in the iPod updater, and iTunes wouldn't aknowledge it at all. I tried many things including restore (in disk mode updater worked), changing the drive letter, and the 5 r's. The fix for this problem was simply turning off my anti virus software. Appearantly PC's like to see ipod software as foreign and even though your ipod might work fine for a few days, the anti virus software will eventually mess it up. So all you have to do is disable that and it should work.

hey, i am having the exact same problem but i dont know which anti virus software is doing it. i have a dell with xp what did you disable? thanks!

Fix for Yosemite not connecting to internet or apps

I can't take credit for this I saw another poster from a few days ago but I was having trouble where I could connect to some websites but not all and any app that required internet was not working. I made all of my login accounts admins and that helped. I am now able to use my laptop the way it's supposed to be.
If you want to know how to do this go to system preferences>users & groups>click lock to make changes> allow user to administer this computer> apply then restart computer. I hope this helps everyone like it has helped me

I had the same issue but only fixed doing that:

Downgrade firmware for MAC not connecting

Help still, I have read through all the old posts regarding this downgrade, but really I have maxed myself out doing this and can't even find where to get the downgrade, i went to the FTP directory link in the post but sincerely can't even find it. I have been at this for days, and really know nothing about any of this including the mac stuff my daughters were the ones to convince me this was the way to go.
Anyway please a link to what i have do to downgrade and get my life back.
THANKS!

When using Parallels for Windows 7, I cannot connect to Wi-Fi. I get drop down menu "Real Network Adapter Thunderbolt Bridge used by Virtual Adapter 1 is not connected to the network". How do I fix?

When I try to connect to internet wirelessly (Parallels/Windows 7 on my Mac Pro) I get a drop down that says "Real Network adapter thunderbolt bridge used by virtual adapter 1 is not connected to the network". I can not figure out how to connect - any help is appreciated!

Since you are having trouble with Parallels or Windows, did you ask in their respective support forums? If not, you might want to consider doing so.

Bought my girlfriend the newest Macbook Pro 13" and began experiencing problems with my wifi the moment we got home. Her Macbook would not connect to our home Wi-Fi while my old Macbook Late 2008 running Snow Leopard connected without a problem. Airport would say that it had a Self-Assigned IP address (168.x.x.x). Did not realize it was a Lion problem until after using her Macbook Pro and becoming jealous of the new OSX, I upgraded. Soon after I was unable to go online. Luckily I had my iPad 2 and I began to scoure the net for help. Ran into allot of suggestions but it was not until I tried the following all together was I able to share the good new, from my Macbook. Hope this works:
First go to Preferences > Network and click on the cog next to the + and - on the sidebar and click Set Service Order
     - Move Wi-Fi to the top and click ok.
     - Set location to Automatic
     - Click Apply
     - Click Advanced
     - Click the "-" on the selected Wi-Fi router you wish to connect to
     - Click Apply
     - Click Lock to Prevent Further Changes
Go to your Mac's harddrive, (Macintosh)
     - Go to Library > Preferences > SystemConfiguration >
     - Delete "com.apple.airport.preferences.plist" file
Turn off your computer
     - push and hold Option+Command+R+P
     - turn on computer
     - when the grey screen turns on you will hear the OS X "ON" sound (for lack of a proper term) and it will momentarily restart.
     - you will once again hear the "ON" sound, let go of all keys.
     - this resets your PRAM
Go to Preferences > Network > Advanced > + sign
     - click Choose a Network
     - Select your network and enter password
Viola!!! I tried this on my Macbook Late 2008 and my girlfriends new Macbook Pro 2010

     No you are clearly mistaken. The Self-Assigned IP address problem exists on many Macbook Pro models, including the current model, which I mentioned as being the original computer with the problem. While my 2008 Macbook is older it was working perfectly on Snow Leopard and didn't suffer issues until switching to Lion. So clearly the problem exists on the operating system and not so much the hardware.
     I called Apple Support and they had no fix for the problem and told me that this would hopefully be addressed in a subsequent update. It wasn't until I came accross the answer after trying many different methods that I got both of the Macbooks to connect to my router. Otherwise I wouldn't or could not have been surfing the internet for the last 4 months.
Cheers.

I have an AT&T contracted iphone 5. Cannot send mms to anyone but other iPhone users. If you search the Internet, you'll see that the problem is everywhere...both the carriers and Apple are actling like the problem belongs to the other, or feigning any knowledge (which is kind of funny since the no MMS thing was in an ios6 beta that was released awhile ago, so I KNOW apple knows about it). No, I'm not running a beta (obviously, I just got my iphone 5). Awesome. Have a great camera on this thing, but cannot send OR receive MMS from anyone other than other iphone users. Gotta love it.

Suddenly my imessage and facetime stop working both for iphone4 and ipad, i tried possible online solutions but it didn't work. Message such as "could not connect, check your network connection" etc... Help please am getting frustrated here....

Have you tried re-booting your WiFi router ? It may seem OK on your PC, but a re-boot may help.

looks like this is your network connection settings problem, you'd better only keep one network adaptor online and linked, if you do not understand how to setup windows routing, this is completely not firefox problem. buddy. wish you goodluck.

Hi, Kozou. Welcome to the forums!
Connect your computer to the Express's Ethernet port and open AirPort Utility. Does this allow AirPort Utility to find your Express?
If so, go through the setup process. After the Express restarts, disconnect it from the computer and connect it to your DSL, cable modem, or whatever provides your internet connection. Wait a minute or so. The light on the Express should turn green.
Now tell your MBP to join the wireless network created by the Express. You can do this using the AirPort menu or the Network pane of System Preferences.
Does this work?
