MacBook Pro :: WiFi Internet Connection - Network Configuration Changed
Apr 2, 2012
I'm looking for a solution to my WiFi internet connection. I haven't used my MacBook Pro laptop in the last week or so - which means there is no way I have done any changes to the network configuration. However when I now try to connect to the internet via a Hub - which is previously set up on the macbook and worked no problem - is now not working at all.
Info:
MacBook Pro (13-inch Early 2011), Mac OS X (10.7.3)

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.

I have a mixed Mac/PC environment - Macbook Pro (snow leopard); iMac 21 (leopard); 2 x Dell laptops (XP) - and an existing wifi network from a Belkin 8233-4 N modem/router. Also connected to the wifi network is a WHS for backing up the laptops; an HP printer; 2 iphones; an xbox 360; and a Wii.
I've just bought a 1TB Time Capsule to use to back up the Macs as my previous external time machine hard drive just died (which was connected via USB to the iMac).
At the moment, I've got the TC set up to join my existing wifi network (it's connected via an Ethernet cable from the Belkin wireless router), however I'm getting issues with the wifi network not working properly and being unable to connect to the internet. Every time you wake the Mac, you have to manually reconnect to the wifi (and sometimes even re-enter the password), and things work OK until the Mac goes back to sleep. When I go into the Airport utility, the settings say that the TC is set to create a new network, so I reset it back to join an existing network via ethernet, but then if I go back to these settings a little later (after having problems with the wifi connectivity), they have reverted back to create a new network !
What am I doing wrong ?

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?Â

For the past few months I've been using my mid-2007 MacBook (running Snow Leopard) with a Samsung external TV/monitor (with the MacBook's lid closed). I had no problems whatsoever in terms of internet connection to my D-Link DIR-655 router. Yesterday for the first time since creating this setup, I took the MacBook with me somewhere. When I returned the MacBook to my network (closed lid, plugged my monitor back in), I started having WiFi trouble. The WiFi was initially running very slowly and then not at all. The WiFi icon on the menu bar was showing regular strength, however.
The complicating factor here is that when my MacBook is on, all other computers on the network show getting WiFi signals but the connection isn't working for them either. When I turned off my MacBook and powered down/up the modem and router, other computers could connect successfully. (But when I turned my MacBook on, the computers lost connectivity to the internet. I've already played with the router's channels without success. I also made sure there weren't any unnecessary items in my Mac's DNS listing.

All day, I am able to use the internet (via WiFi connection) at the library. But when I get home, I can't connect to my home WiFi connection. This was never an issue before. I have done all of the obvious things (resetting my router, clearing saved connections from my computer and joining a 'new' network, check and installed all updates, etc etc), but nothing seems to work. All the other devices in our house are connected to the WiFi just fine.
I run the diagnostic and I'm only green on WiFi and WiFi settings, with network settings and ISP fluctuating between yellow and red, and internet and server is always red. I have tried DHCP Lease renewel (which usually does the trick when I am getting an invalid IP address (169.xxx.x.x) until I get a valid one (192.xxx.x.x). But now sometimes I'm not even getting an IP at all! All I wanna do is unwind, check/reply to emails just surf the web to decompress after my long days.

So my 6 month old Unibody has had an issue for a while that it drops the internet connection, though keeping the network/WiFi connection. It started out just on campus where there is a campus wide SSID that is unencrypted, though requires a login to start browsing. A restart of the computer fixes this issue, though it always repeats itself (usually after 30-45 minutes of browsing, no downloading). Lately, the issue has been getting worse. It is now dropping the connection on other APs, and even stops the Airport card altogether (KisMac can't even scan). I had a backlight bleeding issue fixed by Apple. Is this connected? I know the airport card is in the screen, so maybe they didn't fix it well.

There's something wrong with the Wifi connectivity on my Macbook Pro. Every few minutes, I lose connection to the internet even though it says I'm still connected to my network. I have to turn Wi-Fi off and then on for it to start working again. It only works for a few minutes and sometimes hours, but then I have to turn Wi-Fi off and then on agian. It only happens on my MacBook.

I use a 4G Galaxy Nexus to broadcast a private WPA2 network. The 4G signal is always strong, and I've verified that the internet is active on the broadcasting device, and that other non-Apple devices maintain a solid connection. However my macbook pro does not lose the network connection, the internet stops working only on the macbook pro and I must "turn Wifi Off" and back on using the top right menu icon in order for the internet connection to resume working on the laptop. It will stop working every 5-10 minutes.

After switching to a new provider and getting a new dsl modem (a fritz!box fon 7390) I tried to setup my homenetwork again. Now the weird thing is: my Mac Mini running OSX Lion Server doesn't seem to be able to connect to the internet over its ethernet port, only when using a WiFi connection...When it's connected with ethernet it can reach the dsl modem without any problems, but it can't ping/telnet or anything else through, only over WiFi... As long as I use the mini servers WiFi connection everything works fine, but that doesn't make any sense to me.I've checked the servers setting and the Fritz!box settings and I can't seem to find anything obvious. Of course I could just go on and use the WiFi connection...
ps: all the other computers can connect fine using either wifi or regular lan connection... I even tried the exact same cable with another laptop just to make sure...

I am on a Mac Mini connected to the Net via a FON wireless router and Ethernet directly to my broadband modem. I have had problems with both the modem and an Airport Extreme, which eventually died, but I am back up again with the modem via the FON router.The odd thing is that I can't get Ethernet to work over a direct connection to the modem. Diagnostics tells me that the ISP and Internet fails. I can connect to the modem over Ethernet, however, change its settings etc. in my browser. There are solutions mentioned here involving changing the etc/authorization file, but wouldn't that also affect the WiFi if that was the problem?Â
In short, Ethernet connection to modem works. WiFi connection to FON router and then to the ISP and Internet works. But the Ethernet configuration does't go that last bit, it only works locally. Using that route, I can't connect to the outside world. I have restarted the modem, the computer etc., but that should not be the problem as both works over WiFi, using the same settings for the modem. How do I best troubleshoot this? I am getting an AirPort Express, perhaps it will work better with the modem that the computer itself, but I doubt it.

I recently switched cable providers to Time Warner. They set up a Ubee cable modem and all devices (IPhone, IPad, AppleTV, etc) are all connecting to the wireless network except my IMac.  I tried renewing my DHCP lease, updating to OS X Maverick but every time I try and connect I get an error message that says "Connection Time Out".Â

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?

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.

I have: Power PC G5 dual 2.3 w 10.4.11 os, Lost Internet connection. (ethernet cable direct to router), No known cause. Checked router,cable etc. All work fine w other computers etc. router does not "see/read" when cable connected to G5. I figured Ethernet card is dead. Can't afford new card figured I'd try: Net gear G54 wireless USB adapter, just to get back online. Downloaded driver for Mac etc. Went to System Prefernces to set up. Opened System Preferences then Network, Automatically this message drops down: "Your network settings have been changed by another application" When I click "ok" same message automatically drops back down. Cannot access "Network settings" at all.

I have had my MacBook for 6 months and it has worked just great with my WiFi network and any other WiFi I have happened to connect it to. This morning, while I was downloading some files, my internet connection died on me. At 1st I thought it was my provider and I usually fix that by restarting my Router. I did that, but nothing happened. I could detect and connect to my WiFi but I had no internet access! My wife's PC and mobile phone connect perfectly well to my WiFi and so does my iPhone!!! My MacBook now only works with Ethernet. Let me add that I have the 13.3" MacBook unibody running the latest Leopard 10.5.8. software upgrades.

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.

I have an older G5. Running Ethernet cables across the hallway is not going to work. Is there a Wi-Fi card, chip, usb solution? Or can I share an internet connection with my MacPro in the same room?

I am having internet connection issues with my MacBook Pro 2011 - running the latest version of Lion OSX. My connection cuts out regularly (every 10 - 15 minutes) despite having a full wifi signal. It is happening on two different routers, in two different locations with two different ISP's.Â
When I run Network Diagnostics ISP is the test that fails, but after a couple of seconds diagnostics fixes it until the next 10 - 15 minutes. The only other alternative is turning wifi off and on. Both of these only last for the 10 - 15 minutes before it cuts out again.Â
It is very frustrating and research online seems to indicate it is a Lion issue. I have made an appointment with a genius, but browsing online it appears there is no solution. It is not acceptable.

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.

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.Â

I have a Mac Mini running OS 10.6.8. Â
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.Â
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. Â
I have tried everything that I can think of but just can't get it working again. Â
The same symptoms occur for both the wired ethernet and the wireless connection with the build-in airport.Â
