Mac Mini :: Ethernet Port Seems To Have Stopped Working?
Apr 16, 2010
I've been having an annoying problem lately. The ethernet port on my Mac Mini seems to have stopped working. It happened when I was switching routers. Most likely I just unplugged it from the old router, and into the new one. After that, no more connection, nothing changes when I plug something in.
As far as troubleshooting goes, I've plugged it into other ports, and into my MacBook Air (Just to get a Self assigned IP) and nothing works. I know these ports work with my other computers. I've reset the SMC and PRAM.It works in bootcamp so this makes me think it's not hardware. Any other suggestions?

I often watch movies streaming on the internet by connecting my Macbook to my television via my Mini DVI to S-video adaptor cable. Last week, however, it suddenly stopped working. The television can still detect the display, but the image is super distorted and moving in a static-ey way. I can only vaguely make out the icons on my desktop on the TV screen. I thought that perhaps my adaptor cable was at fault, so I bought a new one - but the problem remains. I have also tried resetting the PRAM, repairing the disc and permissions with Disc Utility, and cleaning the Mini DVI port. I am pretty certain that it is a hardware problem with the port itself. One of the pins on my Mini DVI port looks like it could be out of place. It is kind of squished at the bottom of the port instead of laying flat like the others. I’m thinking that this might be the culprit. Is there a way to repair the port without having to replace the whole logic board? The Macbook in question is a 2008 Core 2 Duo running Lion.

I have a 15" unibody MBP bought in Nov '08.
Had been using the Mini Displayport > DVI adapter just fine with both HDTV and Dell monitor, BUT then all output has stopped completely!
No monitor is detected by the laptop (although the display does blink blue, as if it had detected it), tried different cables, different displays, using the Displayport firmware update, speaking to Apple, deleting the com.apple..plist files, etc
Edit: it also doesn't work in XP on Bootcamp

How many of you would like to see a HDMI Port? Why the miniDisplay port? Why not remove ethernet jack and miniDisplay port and replace it with a HDMI port. That way one HDMI cable feeds digital video AND audio. Am I the only one thinking of this?

My ethernet port is not working when cable is plugged in. Wireless works fine. Ethernet was working up until end of Feb. Then I turned it on and it wouldn't connect. Plugged into a friend's house still not working. Tried at work, still no luck. (I'm on a MacBook Pro late 2008)

I have had my 24" 2.8GHz iMac from November 2007 flawless until today, 1 of 3 usb ports on the back simply decided to stop working. my keyboard, when plugged in, does not work, however, I usually use this one port with my iPod, when I plug my iPod in, it turns on, says its connected, then ejects automatically, though in the other ports...it works fine in the other ports.

The ethernet connection has stopped working on my MacBook. It has worked previously but now says no cable is installed. I have looked at the port and no damage is noted. I tried a known good cable from another system to no avail

2009 iMac running Snow Leopard.
NO issues until this morning. Put computer to sleep and it would not boot back up properly (stuck on Apple boot screen and it FINALLY came on after many tries). Now my wifi or ethernet won't actually "connect" to the internet. It says connected under network preferences and it's green, but I have no internet connection...

I'm renting a house for the week with several friends, and there's only one ethernet port. I figured I could plug one friend's Powerbook G4 into the ethernet, go into Sharing, turn on Internet Sharing, and then nearby computers could borrow the connection - this isn't working. The network doesn't even display on my other friend's powerbook. The little upwards arrow does not display ontop of the airport icon in the menubar, which I think it's supposed to, what's going wrong? I have "Personal Web Sharing" turned on under "Services," still no go...

When I plug a set of headphones on my macbook pro, it no longer recognizes that headphones are plugged in. I have tried three different sets of headphones just to make sure that they are not the problem. In Sound/Output section of system preferences, it still says internal speakers even when the headphones are plugged in all the way.
Is there a fix for this I can do myself or do I need to take it in to an Apple Store?

I hooked my Macbook mini-display port up to my new Sony 32" TV and it worked fine for a month or so, but then it stopped working. Now when I plug it in the TV says there is "no signal" and the laptop doesn't detect the display. Nothing happens when I plug it in. I have tried two different HDMI chords, but only one mini display chord.

The Firewire port on my MacBook has stopped working. Nothing responds and when you look in System Profiler with anything connected the Firewire section shows the spinning indicator for a few minutes before claiming it is unable to list devices. I have also tried all the usual troubleshooting steps including resetting the SMC. But, if I put my thumb under the connected Firewire plug and gently press upwards the port works. It shows in System Profiler and drives mount. I have, of course, tried with different cables to rule that out too.
It clearly seems to be a physical problem with the port somehow. Does anyone have any ideas of exactly what the problem might be, and how easy it is to fix? Maybe a pin just needs bending outwards, or the port loose and can a clip needs pushing back in. If it is likely to be something relatively simple I am comfortable with fixing it myself, but the laptop is a few years old and not covered by AppleCare so I am wearing of an expensive repair bill.

I have used ssh port forwarding in the past,I have recently upgraded to Mavericks, but it does appear that my ssh port forwarding stopped some time before this. The last time I know it worked was 5/14/14, and feel it has worked more recently as well.
from my Mac I ssh to my work jump server (port 22, let's say its IP is 11.22.33.44), and my jump server has access to work PC (lets say IP of 10.1.2.3). My work PC has RDP running on it on the common port 3389. I have verified that I can set up a working RDP session at work from another box. Also, I know that my jump server can get to my PC at work as I can ping my work IP if I just ssh straight to my jump server. And I know that there is no firewall stopping me from the jump server as I can also open a telnet session to my work PC on port 3389, without errors.
how I have done it in the past and it has worked, but now recently stopped working in Terminal app:
ssh -f me@11.22.33.44 -L 3388:10.1.2.3:3389 -Nnv
The verbose logging shows that it sets up connectivity. If I then look to see if my local port is listening I can type:
netstat -an | grep 127.0
I will note that port 3387 is in fact LISTENing and waiting for connection
I then start my RDP client app, and start a session to "localhost:3387" (I could also use "127.0.0.1:3387", and have, but it does not work either). My RDP client eventually times out. I have turned my firewall off and on, neither way works.
The verbose log shows the following is setup appropriately (with noted modifications to server names and actual IPs): debug1: Authentication succeeded (keyboard-interactive).Authenticated to somewhere.net ([11.22.33.44]:22).debug1: Local connections to localhost:3387 forwarded to remote address 10.1.2.3:3389debug1: Local forwarding listening on 127.0.0.1 port 3387.

I usually use an ethernet cable to connect to the internet. I recently bought a time capsule and in trying to set it up i plugged the capsule into the ethernet jack and my ethernet cable stopped working. I connected my computer into the capsule and its not the cable thats broken. I'm currently lost on what to try next, when i connect my computer to the jack, it says "nothing is plugged in" or something like that.

I just got to college and discovered that wifi didnt work (now I've learned that it only works with Firefox for whatever reason) so I just plugged into the ethernet port at my desk and it worked for a week or so and then it wouldn't work and I checked Network settings and it couldn't detect an ethernet cable. So I reset the PRAM and it worked... for a few hours, and now it doesn't. I don't want to have to do that every time I come back to my desk. What should I do about this? (and any suggestions on safari/chrome not working? I posted it in another subforum on here but I got nowhere)

I seem to have a problem with my ethernet port not working after a specific location change...I have three locations I used frequently. Let's call them:
1) HomeWireless
2) WorkWireless (used when I'm in meetings)
3) WorkEthernet (used when I'm at my desk)
My general practice is to change locations just before putting my MacBook Pro to sleep, and then it is happily ready for the desired network when it is awoken.I'm not sure what this change in behavior coincided with, but as of ~1 month ago, I am finding that going from WorkWireless to WorkEthernet, my ethernet port appears to be completely dead and I have to reboot the computer to reactivate it (yes, I've checked the cable itself and the wall port at they're OK). I've tried a couple ways of disabling & re-enabling it in software, but I don't get the impression anything actually resets this interface - suggestions are welcome as perhaps I just didn't try the right thing. I couldn't find anything quite the same as "networksetup -setairportpower" for the ethernet port.Oddly, this is not an issue with going from HomeWireless to WorkEthernet. Both HomeWirelss and WorkWireless have the ethernet interface deactivated in the Network pref pane, and perhaps the only notable difference between HomeWirelss and WorkWireless is that I use a static IP on the former and dynamic on the latter.

I started to have a perplexing problem that I narrowed down to the audio in-put port on my Mac Pro (MacPro3 ,1). It was working fine then the sound level increased and the quality became distorted (like a "fuzz base" but affecting all sounds)I was in the process of digitizing records, and believed the record played broke. So I got a new record player (audio-technica AT-LP120-USB). The same thing occurred with the audio in-put port, so I switched to the USB port and the audio was fine. I also checked with music already on my HD and it played fine. Consequently it has to be the in-put line port and/or a software issue.

I have a Mac/Windows home network with two airport extreme base stations. One is connected to my dsl modem. The other is used wirelessly to extend the network, and I have a Xerox Phaser 5500 connected to one of its lan ports. Until recently, all computers, connected wirelessly could share the internet connection and print to the Phaser. Due to a power failure, I had to reset both the Airport base stations. I can still connect to the internet, however I can not print from any of the computers.

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.

Just a piece of info for those considering driving a 30 inch Monitor with the Mini: The mini-display port to Dual Link DVI adapter Apple is offering is not working. There are some other forums discussing this problem with the unibody Macbook pro. I've been using mine since Dec. At irregular intervals the screen becomes blurry (weird double lines all over), and the only thing that works is plugging back in or (more harmless if you have multiple projects up and don't want them to be scattered all over the screen) Control-Shift-Eject to put the display to sleep, then wake it back up after a few seconds with mouse or keyboard. This can be very annoying as sometimes one has to repeat it multiple times. Apple is aware of the problem, but has not come forward with a solution. I just don't want you guys to be disappointed in your new Mini with a capable graphics card...

as the title suggests, I purchased a Mini Display port to DVI adapter for my Aluminium Macbook but when I plug it in and connect it to my Dell 24inch monitor, it doesn't detect it.
I remember reading about 2 different types of DVI but i was assured that the Macbook supports both types.
Anyone have any ideas?

have been using Mail (to my Yahoo account) for a few weeks. A few days ago it just stopped working. Checked the Connection Doctor, no issues, able to connect with the Yahoo server. I am able to send email, just not receive. After a bit of reading I tried to do the Rebuild but it is greyed out. Also not able to delete email messages that are in the mailbox, I delete them but they are not actually deleted, they re-appear. Now I get a message box 'The file 10217.emlx' cannot be opened because there is no such file'.

today i found that Mail has stopped working for no obvious reason.It wont send or receive emails, but when i check by signing into .mac itself, the messages have arrived and everything appears normal.Mail won't quit either... then every so often a box with the following text appears:'Some actions taken while the account 'enter.mac address here' was offline could not be completed online.Mail has undone actions on some messages so that you can redo the actions while online. Mail has saved other messages in mailbox "on my mac" in "on my mac" so that you can complete the actions while online.Additional information: The connection to the server "mail.mac.com" on port 143 timed out.

Problem:
Apple Mini Display Port does NOT work at resolutions over 1600X1200 on NON Apple Cinema Displays.
That means if you own any other brand of monitor such as NEC, Lacie, etc. you will NOT get native resolution on your 24 inch monitor as it is stuck at a maximum resolution of 1600X1200.
This story was mentioned on "Macbreak Weekly" show 4-14-2009. I have since checked with a few people and it would indeed seem to be true at this point.
I REALLY hope a solution from Apple comes soon and this is not some new policy of theirs. If so, it may be the last Mac Pro I will or can ever own. The reason is I do a lot of 3D work with C4D, Vue, Modo and Photoshop CS4 so I MUST have a monitor like the high-end ones from Lacie that have 100% color gamut and Adobe RGB. I can NOT be tied down to an Apple Cinema display due to that work. At this time, it seems this means I would only get 1600X1200 resolution on that 24 inch monitor.
I am HIGHLY concerned by this. Has anyone else confirmed this too and if so what the heck is Apple thinking or better still going to do about it? I LOVE my Mac Pro but if they start forcing Apple displays on us then I won't be buying another Mac, it's just that simple.

None have worked even a bit!.. Also read lots of forum posts of similar problems, but I can't find a solution that works!
