OS X :: Self-Assigned IP - No Internet Connection?
Mar 5, 2010
I've been having some wireless connectivity issues on my MBP (OSX 10.6.2) for the past half hour. I came back from a jog and all of a sudden I don't have any internet connection...wireless is giving me "Alert: No Internet Connection" and when I go into the network preferences it gives me "Airport has the self-assigned IP address xxx.xxx.xx.xxx and will not be able to connect to the internet. Prior to this, I've had virtually no problems with my internet and I've made no changes to my laptop or gateway (2wire 3800HGV-B, using AT&T U-Verse).
The weird thing is that the two wireless items in my house are my laptop and iPhone, which both lost wireless connection at the same time. While a reboot of my iPhone worked (it can connect to the wireless network fine now), my laptop still can't connect.
I've tried creating a new location in network preferences, no luck. I've changed wireless channels to see if that would work, nope. I've turned my airport wireless on my laptop on and off, as well as restart my laptop, nothing. I'm not sure where else to start...but I'll try to give as much info here as possible, to paint a picture.

One fine day, my iMac running Mavericks 10.9.2 has stopped connecting to internet over WiFi. it is self assigning an IP to itself and refuses to do a DHCP handshake with my router. My other wifi devices can connect to this network without any issues. So us the same iMac when it runs Windows 8.1 on the boot camp partition. I have tried the following fixes, but to no avail:
1. Delete the location
2. Delete networks
3. Reset DHCP
4. Restore Mac to a previous restore point where it used to connect to internet without any issues.
Info:
iMac (27-inch Mid 2011), OS X Mavericks (10.9.2)

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?
Info:
MacPro 4,1 8-Core 2.26 GHz, Mac OS X (10.6.8), 12Gb Ram

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.

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.

I have a VPN service that I can connect to with other computers in my home network with no problem, But my leopard MBP, After connection to VPN server (pptp), the connection to internet dies. I still can ping by IP but cannot with domain names. I tried changing the DNS server of my connection but no luck.
I have to say that this happens after I select the "Send All traffic over VPN connection" option in advanced menu.

My macpro for some reason doesnt have the signal catching strength of my macbook. I want to temporarily use my macbooks internet on my mac pro. I went to sharing and clicked share internet and plugged them into eachother via ethernet, but it didnt work...or i just did it wrong. Is there an easy way to do this?
One weird thing, I clicked on the wireless icon nd clicked create network. i created a network and enabled data sharing...i was able to access all the file on each computer respectively without plugging them into each other....how does this work? If they can share data without being plugged in why cant they share internet!?

I have been using Qwest DSL internet for the past year. But, for the past month I've had a problem with the internet going 100% out (for just 1 minute each time) when I'm surfing the internet or using Skype/MSN. It can happen 10x per hour or just 1x per hour. It happens most often when I'm demanding a lot from my internet connection, such as visiting graphic intensive sites (360 degree tours, etc.) OR when I'm using Skype with video/audio. It's sometimes predictable, but not always. Even if I try to recreate the 1 minute "outages" there isn't a guarantee I can recreate one of them.
Tech support has replaced my 2wire modem 2x. They have also checked my internal and external wiring. They've also changed ports and all sorts of things in the main office. They say I'm getting perfect speeds and a clean signal. They say they've done everything they can. And, honestly, it seems like they really have tried. And, the speeds ARE good, except for when the internet light goes completely Off and I lose my internet for just 1 minute. It then turns back on and the connection returns. (The DSL light and other lights remain on or just flicker).
My computer: I'm using a 3 month old 2.4 MB with Leopard and the basic Mac programs. I also have Skype and Adium, but not much else. No extra firewalls or anything.
My DSL modem: I have a 2wire 2701HG-D. Built in firewall.
Changes: I've not made any changes to my hardware or software. This problem seemed to come from nowhere. Everything was great and then these 1 minute outages started occurring.
Mac/Modem settings: Standard settings using WEP.
Other users: Just my MB (wireless connection) and very occasional use of a neighbor (wireless connection) who checks her email. But, she's often gone. And, these outages DO seem to occur when it's ME online and when I'm using the internet heavily.

I've just got a Samsung BD-P1500, which is enabled for "BD Live" Discs.
It has an ethernet port on the back which I would like to use to get online. Why not :-)
The router I have is too far away to have a direct ethernet connection, so I was wondering if I could use the ICS feature in OSX.
I've had it working for my Xbox previously and it worked fine. Only lag experienced was when I was surfing on the MacBook at the same time.

I am sure this may have been asked before , but I am having a problem finding an answer. I have an iMac (2008) and my wife has a ACER E500 PC (No WiFi connection), running Windows XP Media Edition. The only internet connection we have is to my iMac, so as both my iMac and my wifes PC both have Ethernet connections , I am trying to share my iMac internet connection to my wifes PC via an Ethernet cable, I am having no luck in getting it working.

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?

Since it's possible to use a Mac as a wireless access point. I want to share my Ethernet connection through WiFi (not vice-versa), can I connect my Xbox 360 easily with that network or I have to painfully change the settings?

a few days ago I noticed that my Late 2009 Macbook seemed to lose its internet connection every few minutes just for a couple of seconds only to reconnect. I have no idea why this problem suddenly started occurring, I had not not modified any hardware or software. Strangely enough, this happens whether I use Wifi (at work) or Mobile Broadband via USB ( at home) so I don't think it can be blamed on the internet connection. Stranger still, I should probably not be talking of losing my internet connection but of not being able to access the internet: While again being in a few seconds of slump, I checked my Mobile Broadband Manager and it was not disconnected, upstream traffic was occurring! Just the downstream was at zero. I run windows with bootcamp on the same Mac and there the internet works without trouble. I have all the newest updates installed.

I'm trying to setup my MacBook to allow internet connections to devices via Bluetooth PAN. In other words, getting a Palm Centro/Motorola Q9h to access the internet via the mac's internet connection over Bluetooth PAN.
I've enabled Internet sharing correctly, checked all the relevant boxes.
When the device connects to the Macbook, the Bluetooth PAN connection shows 'active', but it seems that the Macbook is not assigning an IP address, nor routing the packets.
Has anyone had any success with this?

I want to share my internet connection from Airport to computers connected to another network created by a USB wireless device attached to my system.
The network created by the USB wireless is working fine, and computers can connect to it, but they can't access the internet.

Two days ago we changed our internet provider to Bell. The problem is that I have 2 PC computers at my home, both which are connecting perfectly to the internet. However my macbook will not. It appears as though it is connected (full bars) but when you open a page it instantly doesn't work.

I want to share my connection over ethernet, but it is critical that it is passworded as its a large semi-public network and I dont want anyone else using my internet.
System preferences makes it easy to do this over wireless but it gives no password options for over ethernet.

Setting up the bluetooth so that I can use my mobile phone to access the internet on my mac. I have an LG phone but there isn't an LG option in the dropdown bar, does LG perhaps have another name that's in the list. Also what do I put in the username, password and phone number sections? I have tried to do it but it has failed.

I brought my router from the city to my cottage and I wanted to get wireless, however, when I hooked it up to my modem, it didn't work. Is it possible to hook up any old router to a non-wireless internet connection?

I've had my MBP 13 inch (base model) for less than 4 months and I've been experiencing crazy dropped internet connection, both at my house and at my dorm. At my home, I have a 2WIRE portal modem and it drops at least 10-12 times a day and the only way I can reconnect is if I turn Airport Off and On. Same situation at my dorm , only thing is that I connect via wirelessly. Anyone have a solution to make this annoying dropping go away? My roommate has a Windows Vista Laptop (Gateway) and He has perfect connection and can play WoW and COD4 without lag or disconnection. My Windows XP Desktop (eMachine) and My Windows Vista PC (Dell Inspirion) are running on the same portal at home and they both are connected perfectly.

Here is my setup, and I have it all configured correctly, and everything works great. I am able to stream stuff off of the iMac with Connect360, and internet works great. I am not having any trouble configuring the ethernet port to share the airport connection. What I am trying to do now is have the 360 connect to the Media Center PC located downstairs hidden out of sight.
Because the 360 is getting it's connection from my iMac, would it still be able to connect to this MCE PC? (the only PC in the house, whose sole purpose is to be a DVR and eventually, serve the 360 up with cool MCE hacks such as a web browser for the 360, and Hulu). I am not about to buy a WiFi adapter from MS for $100, as that is overpriced and the iMac connection works fine.
