ETHERNET NOT WORKING!!! HELP!!!

Hi,
I just reinstall my snow leopard yesterday. But, the ethernet is not working. When I plug in the cable, it says that there is no IP adress.
I had already:
-reset PRAM
-Create a new location
-MANY Restarts
-try the Ethernet on my bootcamp partition and it works
-Restart my router
-Permission repair
-Change cables
-Change ports
-Renew DHCP Lease
I'm pretty much lost now, AirPort works fine btw. Just the Ethernet. It self assign an IP every time I connect.
It's not a router issue because the windows partition and other computers that are connected to the router seems to work fine. Please help me!!!
Thank you.

Try connecting the Mac to a different router (e.g. directly into a cable or DSL modem or a friend's router). Even if the other computers connected to your router are maintaining their connection to it, there could still be a problem with a setting in the router that could prevent it from sending DHCP information to your Mac (which could explain why manually setting the IP addresses would still work).
If the Mac does the same thing connected to a different router (or plugged directly into a cable/DSL modem), and it's happening in two completely different OSes on the same machine (Windows & OS X), and with ethernet cables that definitely work with other computers, that would be a very strong indication that it is a hardware problem.
If connecting the Mac to another router or modem does work, then you know that it's an issue with the router. You would then need to check its settings to see if anything there could be preventing it from talking to your Mac. You may also need to try resetting it to factory defaults.

New Problem, Old Issue. Ethernet not Working

You may recall this thread: http://forums.verizon.com/t5/FiOS-Internet/FIOS-Ethernet-not-working-Wireless-works-fine/td-p/203838
If you do, well, I have the same issue once more. It's driving me a bit nuts, to be perfectly honest.
About 10 days ago I finally had a stable ethernet connection on my Desktop machine to the internet. 8 days ago I marked the other thread as solved as it was still working and thought that my problems had been solved. Unfortunately, here I am 10 days later and suddenly, without warning, the ethernet connection on my Desktop loses internet connectivity.
I tried turning the router off and then turning it back on, but none of that worked.
Right now it switches between two different states without little indication as to why it switches between them except that it tends to only do it as a I unplug the cable and then plug it back in. The two states are simply connecting to an "Unidentified Network" which is much the same as the problem I had before, and connecting to an "Unidentified Network" with "Internet Access", except, none of the applications that use internet on the computer actually have Internet access even in this state. The Unidentified Network is the key to knowing I still don't truly have internet access.
Windows Firewall is off. It's actually been off for awhile now because I forgot to turn it back on after I initially shut it off trying to get it to connect before. Windows 7 (64-bit) is up-to-date, so that's not the issue either. But something is at issue here and I'm not sure what it is. Since the Wireless works, and the Desktop downstairs works on the ethernet, I can only assume it's something with this Desktop. But I'm not sure what it is or why it's doing this.
Any help with isolating the problem so I can actually fix it and not wait almost two weeks for it to magically work again would be immensely appreciated. Thank you.

Hello there Viafax and Spacedebris!
Apologies for not responding sooner. I decided to take a look at a Windows 7 support forum to see if the issue was something specific to that. After explaining in detail, I got this post and I followed the steps. I posted the information I got and then tried the duplex thing.
The default setting it seems is "Auto Negotiation" which obviously wasnt working.
I tried 100 Mbps Half Duplex and suddenly I had a connection. I can connect to the internet on my Desktop! So I tried 100 Mbps Full Duplex and.... no connection.
So, right now it's set to Half Duplex. But I don't even understand why it would need to be Half instead of Full, or the benefits or disadvantages to either. Right now it's working, but I wish I understood more.
The 192.168.1.25 may have been a typo, since I set the device to run off a static IP of 192.168.1.125, to my knowledge no device on the network has 192.168.1.25
But other than that brief typo, I do believe the rest of the information is as accurate as I could make it. I typed it as I looked for it, so even if it seems odd, that's what it was.

Hi,
the settings are gone, i guess. But even worse, I cannot get the iPad2 to play Full HD thru the Apple digital AV adaptor using apps that support (and advertise this), like AVPlayer HD. This definiteley used to work before one of the last iOS upgrades. (I am now at 5.1.1).

Panasonic .MOV files only play audio no video in Premiere Elements 11??? Not Working Help

Panasonic .MOV files only play audio no video in Premiere Elements 11??? Not Working Help

It all depends on the codec the file uses, Karli.
What model of camcorder is this video coming from?
Are you working on a Mac or a PC? Have you got the latest version of Quicktime, per the program requirements? When you started your project, did you select the settings for a DSLR at 720p? This is a vital step since it will activate the components your computer will need to work with many of these types of files.
BY THE WAY, KARLI--
PLEASE do not post the same question more than once on this forum! You've already got a thread going with this same question and several responses posted. It's very confusing when you post the same question a second time and start a whole new discussion.

Ethernet not working on brand new portable

Ethernet not working. This is a new portable.
Troubleshooting message: The realtek PCIe GBE family controller adapter is experiencing driver or hardware related problems.
Reinstalled the driver multiple times .
Reinstalled the portable to factory default.
Only one ethernet controller driver available for this portable on the HP site so i used that one.

Hi:
The only suggestion I can offer would be to try the driver directly from Realtek. Fourth file on the list.

If that fails to do the job, I recommend you either return the PC if you can, or contact HP technical support and submit a support case under the warranty.

Thunderbolt ethernet not working when computer wake up from sleep.

thunderbolt ethernet not working when computer wake up from sleep.
it will not happen in Mountain loin.

I had this problem on SL and on Lion as well, and it occures for WiFi and Ethernet connections.
In fact the internet connection was not broken as I could ping the destination usin the IP (not DNS name).
In this case the problem was related to mDNSResponder task which handles all dns queries.
It was the most frequent problem in my day to day work with SL and now Lion. It was never fixed by any patch from Apple. I tried almost all voodoo including fresh install, all possible config changes - no solution.
The only version with no problems related to network was 10.5.8. All the other versions had issues of different kind (WiFi instability (lost signal), DNS problems (for wireless and wired connection) sometimes associated with machine sleep and wake up and sometimes with no reason.
QUESTION: Is your problem independent of the access point / router you connect to.
I must say networking was (and still is) the weakest part, besides the other OS X weaknesses I experienced during 4 years of OS X usage.
No problems in the same network with Linux or Windows beeing ran natively on my iMac So hardware is OK.
Software is of poor quality. Not much more to say in this matter.
I found a very interesting article dated 1996 about programming which I think is still valid.
Link to the article: http://www.fastcompany.com/magazine/06/writestuff.html

Software is everything. It also s***s.

If you only restored from backup, restore to factory defaults/new iPod. If you then still have the problem it is likely a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
