OS X V10.7 Lion :: Force System To Use Second Connection Of Network Connection List For Internet Access?

Jul 5, 2012

I have a MacPro Early 2009, 2 ethernet ports.Ethernet 1 is connected to the LAN and Ethernet 2 is connected directly to a SSL Matrix console (an audio mixer), whom driver needs the used ethernet port to be first of the list in the Network connections list in System Preferences.So when I browse internet I can't use the Matrix's software, and vice versa.I had to create 2 different network positions to browse internet and to work with SSL Matrix, one with Eth 1 first place, another one with Eth 2 first place, and I always have to swap positions.Is there a way to force OSX to use by default the 2nd connection of the list for internet access?

OS X :: No Access For Network Connection For Guest Account

Mar 1, 2010

After creating a guest account I noticed that anyone uses that account can use my (remembered) secured network connection. Normally, in my network settings, remembering used networks option is checked. When I look into the keychain, I see two entries for my network name. One is in my logins section and the other is in the system section. I suppose, the guest uses the entry which is in the system section. If I delete the entry which is in system section, it is been created again on next connection.

If I do not want any guest to use my network connection, I am having to cancel the remembering used network option and select disconnect on logging out option in airport advanced settings. But; if do this, I am having to select my network and type its password every time I login. I simply want if a guest uses the Guest Account, he wouldn't able to use my network connection without entering the correct password. Is it possible?

OS X :: Network At Home For Internet Connection

Sep 10, 2010

I am going to move into a new house soon. I am looking to network the house, so I can use the internet anywhere, share movies,etc. This is my current setup at my apartment.
1 x Mac Mini connected to my TV in the lounge
1 x Apple TV connected to the TV in the bedroom
1 x Main PC in the study room (which all my movies/tv series/music/etc... is stored)
2 x Laptops
1 x Apple 20" Cinema Display

The mac mini is connected via ethernet to the router & the apple tv is connected via WiFi. Its currently a small place so the apple tv can access the router's wireless signal. This is what I have in mind for our new house which kinda big in size. Trash the PC and buy a mac mini server and external NAS storage. The NAS storage will store all the movies/tv series/mp3's/etc. I currently have a ubiquity nanostation2 which I can setup to boost the wireless signal throughout the house so we can use wireless anywhere in the house & tv mac mini, laptops & apple tv can access the wireless (so i do not have to install ethernet cables throughout the house). Also in the future, I would want to install security cameras outside the house (still trying to find a good mac OS X security camera software). Before I buy the mac mini server & NAS, am i missing anything or is there another better solution?

Software :: Network Internet Connection - XP Box?

May 16, 2009

Firstly here is my configuration I need help with. My friends windows xp machine has a broadband connection in another part of the house. My iMac connects to this wirelessly via a WiFi dongle. I also have a windows xp machine networked to my iMac via a crossover cable. I would like to be able to have my xp box connect to the internet by perhaps accessing the wifi dongle on my Mac. I know I could just purchase another dongle and do it that way, easier but would defeat the purpose.

MacBook Pro :: "Network Connection The Communication Device Selected For Your Connection Does Not Exist?

Mar 16, 2012

The internal modem in my PowerBook Pro (mid 2010) shows up as "not connected" in the Network pane of system preferences, but I can't figure out how to get it to connect. When I enter my phone number and click the connect button, I get an error message: "Network Connection The communication device selected for your connection does not exist. Verify your settings and try reconnecting." Say what? It says it exists in the System Preferences, shows it in the list on the left. How can it not exist?

OS X :: Leopard Internet Sharing Network But No Connection

Nov 5, 2007

I recently did a clean install of leopard and then migrated my account back on to my MBP non-santa rosa 2.33. Now, when I attempt to internet share from my ethernet to computers using airport, they are able to see the network, connect to it, and put in the password, but internet fails to connect. I'm on a college network, but this shouldn't really matter since I currently have a network of this type working perfectly on an iMac running Tiger. The signal reads at full strength and behaves just like it should, just it doesn't allow an internet connection. No firewall is on.

OS X :: Internet Connection Working Properly But No Access To Websites?

Nov 14, 2010

My Macbook Pro is connecting perfectly to my apartment's internet, but for some reason no websites seem to load. I've tried using Safari, Firefox and Chrome and none of them have worked for me. When I clicked "assist me" it said that my internet seems to be working properly, but when I tried pinging google.com the response was "4 packets transmitted, 0 packets received, 100% packet loss". Ethernet is working perfectly however and WiFi is working on my iPhone and on my roommate's computer. WiFi is working perfectly at the library as well, so I'm not sure if it's a problem with my computer or with the network.

Software :: Internet Connection Hangs Disconnecting Using Mobile Connection (GPRS, EDGE, UMTS)

Aug 21, 2006

I'm on holiday using my mobile phone (Nokia N80) to connect to the Internet over GPRS / EDGE / UMTS. Everything works like a charm, but often the Internet Connect applet drops the connection and just hangs disconnecting.

I'm running OS X 10.4.7 on a 17" Macbook pro, but I have the same result on a iBook G4, same OS X version, and even trying with a different mobile phone (Nokia 6600) and different network service provider.

OS X :: Connect To Home Network From Remote Internet Connection?

Mar 19, 2007

I have a non-fixed IP with BT for my home network and am curious if I can set things up to access my home machines and volumes when I am abroad. A step-by-step guide to this process would, no doubt, be useful to a number of MR members. If there is a kind soul who could post an idiot-proof set of instructions that would be great, and would perhaps be put up as a user guide here at MR.

Mac Pro :: Internet/Ethernet Network Connection Slows To A Crawl?

Apr 1, 2012

The last few days I've had a problem where the Internet network connection speed on my Power Mac slows to a crawl (about 1Mbps) and can only be fixed by re-starting the Mac which restores normal connexction performance for a while. The Internet connection runs at around 35-37Mbps and is routed via a BT HomeHub 3. The laptops which connect via WiFi don't show any slowdown in speed tests, only the Mac Pro, which is connected to the Hub via Ethernet. I've tried swapping between the two Ethernet ports on the Mac but it doesn't make any difference. The HomeHub has been in for about 5 months but this problem has only just started in the last week or so and the period for which the restart restores the network performance seems to be decreasing. Is there any way to reset network software, or some prefs I could delete? It's an early 2008 eight-core Xeon MacPro running 10.6.8, 8GB RAM.

Mac Mini :: Network Connection Fails (Internet And Server)

May 7, 2012

I have a Mac Mini running OS 10.6.8.   

Suddenly the networking functionality has stopped working and the diagnostics fails to fix it.  It shows all green lights apart from Internet and Server which both show as FAILED. 

My router is operational and does assign the Mac Mini the correct IP address (confirmed by the Mac Mini and the Router).  All other devices on the network work and can access the internet as usual.   

I have tried everything that I can think of but just can't get it working again.  

The same symptoms occur for both the wired ethernet and the wireless connection with the build-in airport.

OS X :: Airport Shows Connection (Full Bars) - Can't Access Internet

Mar 4, 2009

This problem has been going on for a couple of months now. I use my macbook at 2 places: school and home. At school, when I click the school network under airport, it connects and shows the full bars. But when I open safari/firefox, the page won't load and I get the error message when you're not connected. However, sometimes after like an hour of persisting and retrying, it will be able to access the internet for a little bit for like an hour or so maybe, and then it'll stop working. At home, it's the same thing. It will connect to my home network (got wireless at home set up through my desktop PC), and show the full connection on airport, but it won't access the internet for the life of me. The difference is I can never gt it to connect unlike at school where it sometimes works, except that it worked for like one day out of the last 2 months (and I didn't change any settings then so it's not like I can attribute it to that). Also, I am absolutely positive that the networks of my home/school computer and the router settings etc. aren't to blame. Reason is that my friends with macbooks can access the internet both using my home network and the school network (the school one is obvious). What could possibly be going wrong? Any settings on my macbook that I can change / completely reset? Is the network card or something messed up? I'm contemplating just completely formatting my laptop to see if it fixes the issue. I have leopard installed btw.

Applications :: Network Monitoring Software For Wireless Internet Connection?

Apr 29, 2005

At home I have about four laptops and one desktop computers. All of them use a wireless connection to connect to the internet. Sometimes, one of my siblings is downloading something huge or is downloading torrents or what not and it cripples the speed for the rest of us.

I also can't see if someone has managed to crack my WEP password and is using my connection (a neighbor or someone). Is there freeware that tells me who is connected to my network and how much traffic or data they are using?

OS X :: Slow Internet On Wired Connection - Fast Wireless On Same Network

Jul 15, 2009

My Internet has just been upgraded from 2MB/s to 10MB/s. To confirm the upgrade I have used [URL:...] to test my upload/download speeds with Firefox and Safari. I have 2 computers on my network which consists of a cable modem connected to a white airport base station with 128 bit WEP encryption in 802.11 b/g compatible mode. The 2 computers are a dual 2.8 ghz MacPro which is wired directly into the Airport base station by Ethernet and an iMac 1.83 Intel core 2 duo. The much faster MacPro only achieves a download speed of 5.5MB/s over its wired connection while the slower iMac achieves 9.8MB/s - very close to the advertised speed over its wireless connection. These are consistent speeds not one offs so I am wondering why the difference? The MacPro is my main machine so I'd like to have the best speed possible on that. What can I try?

I connect with my MacBook Pro via ethernet to the internet. So far, I've never had a problem until a couple of days, I keep on loosing the internet connect. When clicking through diagnostics, ISP, Internet and Server show first organge then turn red. If clicking through the diagnostics, sometimes I am lucky and it shows a message saying "Network configurations have chnaged", when I click ok, I'm online again. But very often nothing helps and I have to re-start the router again.

OS X :: Internet Connection Keeps Dropping Connection?

Aug 12, 2009

I know there are a lot of similar threads all around different forums, but nothing really helped and I was hoping some of you smart ladies/guys can help solve this issue once and for all.

Here's the deal:

My main desktop computer (Compaq windows XP computer) is set-up upstairs where the cable router and linksys wireless router are placed (which is right next to the desktop on the desk). My Macbook (running Tiger and is 3 years old) and iMac (running Leopard and is not even 1 year old yet) are set-up downstairs in my new office. This room is in the basement, however the room is almost directly above the main office where the wired desktop computer resides.

Prior to setting up my office downstairs, my sister lived with my family in the basement and had her windows Vista laptop set-up without any internet connection issues. Her internet never dropped on her laptop, and neither did the connection on her wireless all-in-one printer/scanner/copier. Cell phone reception/internet connection in the basement is also great.

When I set up my iMac and Macbook however a few weeks ago, the internet keeps dropping connection! I do not understand this when my sister had no problems at all with her laptop getting internet connection, when she was living with us. The internet connection will stay good for either 10-30 minutes and then drop, or it could be good for up to an hour and then drop.

OS X V10.7 Lion :: 21.5 (2.7 I5) 8GB 10.7.3 Keeps Dropping Its Internet Connection?

Feb 14, 2012

I have an iMac 2.7 i5, 8GB, OS X Lion 10.7.3.  I purchased this iMac just about 3 weeks ago and from the beginning experienced regular dropping of the internet connection. I have cleared all other networks that appeared in the Preferred Network window other than my own. I have also unchecked the "Remember what other networks this computer has joined" box just in case I needed to. No luck. I am using an ATT 2Wire wireless router that's just over a year old but I haven't experienced the connection drop problem with an older Macbook (about 4 years old) that I also own.

OS X V10.7 Lion :: Keeps Dropping Ethernet Internet Connection?

Mar 5, 2012

I know this has been a wifi issue for many, but this is occurring with ethernet as well on our iMac 2.93. Only began with Lion update. All other 5 Macs (Snow Lep/Lep/Tiger) and several PC's on network have no problem. Have set iMac's internet connections to static/manual ip. Worked for a few days, then back to dropping. This is obviously an OS issue.

OS X V10.7 Lion :: How To Optimize It For Use On A Slow Internet Connection

Apr 2, 2012

I recently upgraded to Lion OS X v 10.7.3, and i like iMail 5.2 when I work from my office or home.BUT, when I am working in the field I often have access to only glacially slow internet via an internet modem, and iMail takes FOREVER to download my messages. Way longer than my pre Lion version of iMail.Is there a way to optimize iMail 5.2 in order to optimize for slow internet connections? For instance, to partially retrieve large messages? Or to somehow deactivate all the synchronizing and other Activity that goes on in the background?

On three occasions now my PC has lost it's B'B network connection during the file transfer process.

I log into an email account, and I click compose message; the internet then disconnects for a few seconds. If I am streaming radio that resets.
