MacBook Pro :: Ethernet Port Doesn't Work
Jun 26, 2012Brand new 2012 MBP 15":
Network system prefs recognizes that the Ethernet cable is plugged in but flips between unknown state an cable unplugged. Never gets a DHCP address. When the cable is unplugged, it stays on the unplugged status.
As a note, I am having trouble getting Parallels to recognize any network connection at all, butmy immediate concern is the ethernet port.

MacBook Pro :: Ethernet Port Doesn't Work In OSX But Does In Boot Camp
Nov 30, 2007Been troubleshooting this one awhile...I even did an Archive and Reinstall....my Ethernet port on my 2.16Ghz MBP won't connect to anything. I get an IPv6 address when plugging into a router, but DHCP never works and a manually assigned IP doesn't work either. Reboot into Windows and it works fine...I've tried removing the Ethernet port, and have futzed with all the settings trying to reset it, but no dice. Problem started somewhere around 10.4.9, I think...I'm on 10.4.11...I reinstalled to .8 and worked my way back up...never works.

Dec 11, 2009Can my AirPort Extreme work via a Cat5 ethernet port within my network? I ask because we've had no luck doing this where as our older Airport Express works just fine this way. Thoughts? We upgraded to the Extreme to extend the signal (and have 2 antennas) and trying to avoid hooking it up to the cable modem box which is even further away than where the Airport Express was located.

View 6 Replies View RelatedIntel Mac :: Firewire 400 Camera Doesn't Work With 800 Port?
Jun 26, 2012I have a firewire 400 camera that i'm using for a project and one firewire 800 slot on my iMac (Late 2009). When I plug the camera in, nothing responds no matter what I do - tried resetting the PRAM and SMC. Compare this to my older iMac (Late 2007) which has both firewire 800 and 400 ports. I plug it in and it pops up using the underlying Quicktime controller api on either the 800 or 400 port no problem. So I figured after trying to install a firewire camera library (libdc1394) which I need for my project which didn't work, that it must be a hardware issue, so I took it to the Apple store. The genius at the store booted the OS (Lion) from a firewire drive via 400 to 800 cable (no external power to the f/w drive was used) and then using the spare 400 slot on the hard drive, he plugged (daisy chaining) in my camera and it loaded! So this suggested 2 things - my OS is corrupt or my card can't read straight from my device but why a hard drive in between would change this is beyond me. I came home and installed OS X on to an external USB hard drive and loaded up from it - so this is a fresh version of Lion, there should be no software issues. Plug the camera in to the I/O board of the iMac but load the OS from the external USB hard drive - nothing happens, the profiler doesn't detect anything at all. On a side note, I installed XP and Ubuntu Linux and they also can't detect it, which further suggests its the device or I/O board when interfacing directly with this camera. I've tried providing the devices with external power, daisy chaining 2 cameras, using a usb hub....nothing works. Just for good measure, I tried to boot Lion off the external USB on my older iMac and again, it worked no problem, which to me really narrows it down to the hardware.
I feel like perhaps the port is a bit dodgy and when the genius daisy chained it, it worked better, but no idea why. Someone said I should get a firewire 400 to usb adaptor
Mac Mini :: 27inch Display Port To Dvi Adapter To Pro Doesn't Work
Oct 30, 2009I just bought the 27in iMac to hook up to my Mac Pro till apple refreshes their ACD.

Apr 14, 2010There was another thread on this that I found via Google, but now I can't seem to find it again. I have to occasionally hook up my Macbook (not a Pro) to various digital projectors at different companies. I bought the $20 attachment thing. I brought it in and have not been able to get any projector to recognize it at all. This is on several different projectors. I try hooking it up both before and after turning the computer on and it doesn't work. I went to "Display" in System Preferences but there is nothing there about changing the display (to "dual" or "mirror" or anything), it just says "Color LCD" and some preferences about size, bits and stretching. There are no tabs. The worst part is that I teach at a lot of tech companies, so the people there should all know how to fix it, but...1.) can't read English that well, and my Chinese is OK but not *that* good, and 2.) they all use PCs. Macs are like aliens to them. So they can't fix it either. The manual is worse than useless.

May 20, 2009I 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.

View 5 Replies View RelatedOS X :: Using Ethernet Port Connection
Jun 14, 2009 I used the MacRumors Buyer's Guide for several months to find the best time to buy a MacBook. I'd never had a Mac before and found it to be so valuable. I hope someone in the forum can be as helpful as the site has been.
Yesterday I bought a new MacBook Pro 13" and as a store option the RAM was doubled to 4GB. Everything has worked well so far, in both OS X and Windows XP through Boot Camp, except for either OS accessing the LAN cable on my home ADSL. Both my portable modem (EMobile network in Japan) and the wireless seem to work with no issue, and both OS will recognize the ethernet port. I'm concerned that perhaps the ethernet adapter was modified when the store installed the memory.
I can remove the ethernet cable from one computer (where it works without any settings changes on my Windows notebook) and plug the same cable into the MacBook and it will not be recognized. The Mac OS error is that no cable is inserted.
However, as it's my first Mac, I didn't know if perhaps some new settings are required to make things work smoothly. Is there any DNS settings etc. that must be set for it to connect? Also is there some kind of connection diagnostic that will specify the location of the error in the machine? I'd like to exhaust any option before shipping this back to the store to be repaired or replaced.

View 3 Replies View RelatedMacBook Pro :: Adding Second Ethernet Port
Nov 11, 2010I'm looking to add a second ethernet port to my MacBook Pro using this product designed for the MacBook Air: [URL:...] Comments on the Apple site indicate that the device can be used with other computers, but I want to make completely sure it's going to do what I want it to do before I make the purchase. The reason I'm looking to do this is that I want to link my MB (via ethernet) to another laptop running Windows 7 Ultimate and use the Microsoft Remote Desktop Client to operate programs installed on the WIndows machine. The catch is that the internet at my current location (a university accommodation building) is also supplied by ethernet LAN and has some kind of detection system that prevents unauthorised routers from accessing the internet. So basically what I want to do is have the university LAN/internet running into the existing ethernet port on my Mac and then connect the ethernet port on the windows machine to the USB/Ethernet adapter plugged into one of the Mac's USB ports. The Windows machine does not have to have internet access. Is this possible? Will I be able to configure the two ethernet ports separately to operate two network connections? I understand the connections would require a different subnet mask and possibly a static IP for the computer-computer connection. That was a bit long-winded in the end.

Feb 12, 2007Recently got a Mac pro. However my room only has one network socket going into my router, this goes to ethernet port 1. Internet works fine, no issues. However my old desktop (that the MP replaced) can't get online now - no second network port from the router into the room the computers are in. I have a crossover cable that I've used to connect the 2nd MP ethernet port to the PC ethernet port. However I can't get internet access on the PC. If the PC and port 2 are on their own subnet (not the router/port 1 subnet) I can get file sharing going between the MP & PC, but cannot figure out how to get the router/MP/PC on the same subnet together using both ethernet ports of the MP. I have already tried enabling internet sharing under system prefs etwork, but it doesnt work. Network: Router (connected to internet) at 192.168.1.1 - connected to mac MP port 1 - 192.168.1.2 - works fine in connecting to the net MP port 2 - 192.168.255.1 - works in networking to PC for filesharing PC - 192.168.255.2 - works in networking to Mac for filesharing Any combination of 192.168.1.xxx for the MP port 2 and PC, they can't fileshare anymore and there is still no internet for the PC. Anyone know how to do this?

However, it is not working. The router is broadcasting, but the internet isn't working (and the light indicating internet connection on the router is yellow, not green). Is this something that isn't possible? Or do I need to change settings (not just plug and go)?

View 3 Replies View RelatedMac Pro :: Directing Traffic To Second Ethernet Port?
Mar 23, 2012What is the process used to direct certain IP addresses or a range of IP addresses to the second ethernet connection on a Mac Pro? I have a set of Mac Pros that use the first connection for internet access and corporate server connections using Samba. But the second ethernet connection is used for a lan between the Mac Pros and printers. It currently works but it take a bit for the "connect to servers" dialog to connect to a Mac Pro on the lan because I think it is searching Connection 1 first which has hundreds of Windows servers attached to it. And it takes several minutes to connect if our service has an interruption on Connection 1. All of the Mac Pros and printers are set up to use a manual IP address (192.168...) The Mac Pro workstations use Snow Leopard and we have a Mac Pro Server running Lion Server that we use to conntrol a network RAID.

Power Mac G5 :: Ethernet Port Connected To BT Home Hub?
Nov 29, 2007I have a G5 DP 2.0 and have been using it's built in ethernet port connected straight to my BT home hub (adsl/router) for years. Any way I add into the mix a netgear 1000Base layer 2 switch and the G5's ethernet doesn't work, reconnect straight to the router and all is fine. Now tested with new cables and tested on every port on the switch. By the way the port light on the switch don't light up when G5 attached. Now have tried the switch with a g4 and all is fine on every port and supprisingly I've stuck a PCI card in the G5 and that works as well. Just can't work out why the built in won't work through the switch but will direct.
