MacBook Pro :: Does Not Recognize Ethernet Cable Or Connect To Wireless
May 4, 2012
Today when I turned on my computer, it suddenly would not recognize any kind of Internet connection. The Ethernet cable that I use every day now shows up as 'unplugged' even though it is plugged in. I have tried using a different cable, and it still shows up as unplugged. When I try to connect to the Internet wirelessly, there is always a connection timeout and I can't connect. I use a self-assigned IP address and I've never had this problem before. I've also reset my PRAM, but it hasn't worked.
Info:
MacBook Pro (13-inch Mid 2010), Mac OS X (10.7.3)

Okay, so I'm using a late 2013 27-inch iMac, Intel Core i5, running OS X 10.10 Yosemite Beta 2. I've usually just used wifi, but decided to make the switch to a wired ethernet connection. Now the Network settings shows no option for ethernet, so I added a new ethernet connection in the settings. I was then met with a "Cable Unplugged" notice. And I have tried everything to fix it. First of all, I've tested 3 different ethernet cables, and none worked, but all three worked on my 2 Macbook Pros, both running 10.10, and there was no problem. I've cleared my PRAM, reset my power, checked that my ethernet pins weren't damaged, and every other suggestion I could find.

iMac, OS X Mavericks (10.9.2)

I'm here at university and the wifi here sucks! it is so slow, it is working.However there is an ethernet port and I did connect to it this morning. But, this evening I tried connecting again and it wouldnt let me!At my university they require you to put in your student ID and pw in order for you to use the internet for both wi-fi and ethernet. But when i tried this evening it dint ask for my student ID or password. I went to settings and it did say that there was a connection and that "Ethernet has a self-assigned IP address and will not be able to connect to the Internet"
i dont understand how come now it isnt working. I aksed my classmate nextdoor if his internet port was working through the ethernet port he said it was.... i am not that tech savy so keep vocabulary to something simple lmaooo.

I have two G5s, one next to my ethernet/DSL line which plugs in directly for internet, and a second out in the living room where there is no DSL line. However, the house has wireless via an Extreme and two Xpress socket-plug-ins. My mac guy told me that I should be able to hook the G5 in the living room directly into the Xpress next to it via an ethernet cable (the living room G5 does not have a wireless card in it) and the wireless internet should link up via the Xpress to ethernet cable to living room G5. ? He said to make sure I had the ethernet configure box set to "using DHCP" which it is and it should automatically find the right IP address. When I try it, I get nothing though, just a message that there doesn't seem to be a network connection.

I just got a new MacBook Pro, but my wife uses my old 1.25GHz Alum. PowerBook. My MB pro flies, but unfortunately, the wireless ethernet on my old PB is slow as hell. I've got 11+GB of free space left on my hard drive and Safari or Firefox are the only applications I have open. I also have a cable internet connection with wireless through my 1st Gen Airport Express, yet it's still slow.

My father in law had a power failure at the house, and since then, he cannot connect to the internet via DSL Modem connected via ethernet cable. Being that he is 1000 miles away, I am trying to diagnose via phone. System Info: Imac 17", purchased new around 2006- Intel chip, running Tiger OS
Symptoms:
- Cannot connect via ethernet
- When searching system profiler, "Built-in Ethernet" shows up, but no MAC address
- In Network settings, he can see the various connection ports, but cannot check the box on "Built-in Ethernet" to turn the port on... won't let him.
- Wireless is not an option, I don't want to be 24/7 tech support
Diagnosis? I am thinking that the power surge may have fried the ethernet port on the motherboard.
Repair Solution: Planning on picking up the Apple USB Ethernet adapter. I know it doesn't have the correct drivers to run on Tiger, but found a driver online that claims it allows use of the usb adapter on Panther on up.
Questions - Does this sound like a fried ethernet port? Any other easy diagnostic tests I can do? Does the USB adapter sounds like a decent solution?

I have an Xbox 360 set up in my bedroom which is at the opposite end of the house. I have an airport extreme base station (new model) connected to my modem and PC (PC is not wireless, thus why i have it connected).... I have the wireless adapter connected to my xbox 360. I can play online with no lag (game: modern warfare 2) when nobody is on the pc but when someone is on the pc I get very noticeable lag. I guess I am fighting to split the connection with the pc. What is my best solution? 1) Have my ISP boost the speed of my modem. I didn't know if this would help by giving us more speed to fight over. 2) Get an Airport express and set it up closer to my bedroom/xbox 360. Will the express still fight for the connection with my pc like my wireless adapter on the 360? 3) Get the airport express and connect it directly to my 360 with an ethernet cable. Will i still be fighting for connection with the pc?

i can't connect to the internet via my ethernet cable, but this is a weird case. What's weird about it is that all my settings are O.K. (appletalk on and set to ethernet, tcp/ip set to ethernet, dhcp) and my iMac is recieving a 192 address, but it still can't connect to the internet. The dhcp settings are correct, because they are the same settings used on all my other devices (at least those that use internet anyway), and they all connect to the internet just fine. Whether via an ethernet cable, or Wi-Fi.
Info:
iMac, Mac OS 9.2.x

I have a Canon Vixia camcorder that I use, alot. I use the mini dv cassette instead of the memory card. I would like to transfer the mini dv cassette to my macbook.
What kind of equipment do I need? I know a need a firewall cable. There is a Hd/DV outlet. But, is there anything else?
If I connect the firewall cable should iMovie recognize it immediately? If not what other software do I need?

I live in a shared house and connect both my iMac and PC laptop to the internet via Wifi.
This is fine for the internet, but I'm constantly transferring large volumes of files between my laptop and iMac and it's unbearably slow. I can't connect to the router via ethernet because it's in the living room.
Can I connect my laptop and iMac up with an ethernet or USB cable for fast file transfer?

I'm having a problem using my Built -in Ethernet. I have iMac running Macosx 10.4.11. Everytime I connect a cable it doesn't register it in the Network Panel, It tells me that, 'The cable for Built - in Ethernet is not plugged in.' I have tried a couple of different cables, neither work, but they do work with my Macbook running Macosx 10.5.6. So I don't think there's a problem with the cables. Do I need to configure anything or should they work automatically as they do on the Macbook?

I'm brand new to Mac. I just got a MacBook Pro, and I've been having some troubles connecting to the internet at home. I have a LinkSys WRT54GS router with Firmware Version: v1.50.9. I'm unable to access the internet through both ethernet and wireless. Concerning wireless, I have tried connecting using WEP, and have tried entering passcodes both with and without an "$" and "0x" preceding the 10 digit WEP passcode. I have also tried switching the encryption over to WPA2, and still nothing. I have even disabled the security to see if it's able to connect -- it's not. I had some error regarding not being able to find it's IP or something along those lines.

I was wondering how I could file share, or make the whole Hard Drive (HDD) accessible to another computer. The two other computers I have are a Toshiba Laptop with Ethernet and USB, and a iMac Intel with Firewire, USB, and Ethernet. Putting these to use along with:Three Ethernet Cables Now how do I get the whole HDD visible to the others computers (either/both) and be able to write to it? Also, I do not want to use CDs and have no CDs that came with the computers. I want to put Xubuntu on the eMac and Debian on the iMacs and erase the rest of the Hard Drives. The computers getting this are the iMac G3s and the eMac G4 in my Signature.

I was just wondering if any other macrumorsmembers have been in the situation where there's no wifi, no decent 3G, but ethernet ports available to use, but you don't have a computer handy? Would it be possible that you could create an ethernet cable one end, dock the other, and literally connect e.g. an iPhone into the ethernet? At my place of work, there's no signal (dodgy GPRS/flakey Edge), some wifi, but in halls of residence, you get 1 ethernet port, and you can't put a wireless router onto it. It would seem that it would be an interesting solution, if it was possible.

2010 i7 15'' MBP. I've been connected to the internet wireless with my Airport Extreme from day 1, but today I wanted to give the ethernet port a try and it just didn't work. The ethernet cable is recognized, but it says there is no IP. I do not know my IP settings or any of that. What do I do?

I have tried searching for a similar question but have not been able to find an exact match. I have a new MacBook, a PS3, a Virgin Mobile USB and an Ethernet cable and I thought putting them all together so I could use the PS3 online would be easy! Could someone please give me a step by step process of what I am meant to be doing.

When you get home at your desk, put your MBP on the table plugging it to an external monitor or not, do you keep it running on WiFi or do you plug in an ethernet cable for your notebook? I am on a 25mbps line in my home and i find that when i plug in the cable my internet connection is more stable, faster and doesn't drop out sometimes. Because, sometimes on Wifi, websites take a little longer to load or it seems to not load at all. While on the ethernet cable everything is just speed of light instant.
I have also noticed that using vmware when i go away from the computer and puts windows to sleep, when i get back, it takes a while for windows to recognize the airport vmware driver and connect back to internet, while with the ethernet cable it is just instant (again). Noticed this while running windows live messenger and the time it takes to connect back. I also noticed that transferring files from my windows vista desktop computer to my macbook was alot faster on ethernet cable than on the wifi connection, even though my router supports 54mbps wifi. So are you guys satisfied with your wifi? Or do you use an ethernet cable for stability? Or am i the only one with minor wifi problems?

I was wondering if anyone knows if its possible to share my LAN internet to an XBOX 360 using the Apple USB ethernet cable (for the Macbook Air) on my Macbook Pro 13"? I've tried several routers, and all have them have failed me giving me massive timeouts and sudden disconnects. I think this should be a good solution.

All of the 15in cases I have seen in my time shopping online force the power cord to run towards the keyboard vs run to the back and in doing so, blocks the ethernet port. Are there any that do not exhibit this attribute?
