Ethernet connection repair on G3 B&W

After lightning struckour driveway, I have lost the ability to connect to the internet. Other applications are working. My other mac connects fine. What do I need to repair the ethernet connection?

Hi, Jimbo -
Welcome to Apple's Discussions.
How is the machine connected to the net? Dialup, or broadband? If broadband, is it through a hub, switch, or router?
Start by checking the hardware items not shared by the other machine - for example, if a common router is used, and the other machine connects, the router is probably okay. Just to be sure, though, try using the port on it that the other Mac uses - sometimes a voltage surge can blow out just one port on a device such as a router.
In particular, check all cables - swapping out with known-good ones is often the easiest way.

Help with PC- Time Capsule direct ethernet connection

First let me say that PCs are a total mystery to me - I am a Mac person all the way. That being said, I do own a PC for the occasional situation where I can't do what I need to do on a Mac (something that is happening less and less these days).
I just got a TIme Capsule that I configured through my MacBook and which is working fine. I am trying to hook up my PC (which does not have wireless capability) via a direct ethernet connection. The PC seems to recognize that it's on a local network, but cannot connect to the Internet. I have tried going through the various network configuration wizards on the PC and nothing seems to be what I need. Help has been useless. Can anyone help give me some hints about what I need to do to get the PC to recognize that there is an Internet on the other side of the Time Capsule connection?

I am still interested, thanks! Just couldn't get to things during the week. I am running WIndows XP Home Edition. I have to ask you to spell out things a little bit more. To start with setting DHCP - I am not sure how to do that. I tried using Help and it gives me nothing useful.
When I run Network Connections I see a Local Area Connection listed. Type: LAN or High-Speed Internet. Status: Connected: Device Name: Broadcom 440x 10/100 Integrated Controller. Phone # or Host Address: <blank> Owner: System.
Double click it, get Status: Connected, Duration: <counting up> Speed: 100.0 Mbps.
Under Support, Connection Status, everything is blank (Address Type, IP Address, Subnet Mask, Default Gateway). This does not seem good. But I am not allowed to enter anything on this screen. If I click Repair, it says "Window could not finish repairing the problem because the following action cannot be completed: Failed to query TCP/IP settings of the connection. Cannot proceed. For assistance, contact the person who manages your network. (LOL - that would be me)"
There's a control panel for the Broadcom Advanced Control Suite. The IP Address is 192.168.0.101. I don't see anything there about DHCP or TCP/IP.
There's an "Internet Options" controller, where I found an Internet Connections Wizard, but that doesn't seem to do it. I say I want to connect to the internet using an ethernet connection, and then it says "Your broadband connectiion should already be configured and ready to use. If your connection is not working properly, click the following link. (Which is "Learn more about broadband connections"). This is a help page that sends me back to Network Connections (where I started).
Nowhere have a found a place to set DHCP or addresses.
Please, if you can, tell me where to look to adjust these settings. Thanks very much for your help.

Fix for temperamental ethernet connection?

Wireless is working fine but I've developed a problem with my ethernet connection. It connects some of the time but very rarely when I launch Safari. It will work for a few minutes and then stop. I get a series of red lights in network diagnostics. I think the problem preceded the infamous security update which affected my machine but which I was able to resolve.
I have repaired permissions, deleted the plist files in system configuration, created a new location and manually entered the settings. But to no avail.
My G4 is six years old and I suspect that I should not have upgraded to Tiger because there seem to be some compatibility issues (for example, I can no longer reliably use an external monitor because my machine is often forced into sleep mode when the monitor is connected).
Does anyone have any ideas?

Hi JBKL, and a warm welcome to the forums!
For the Ethernet Location... Is that Interface dragged to the top of Network>Show:>Network Port Configurations?
It may be that the Router needs a Firmware update to keep up with the OS Updates... check online, don't trust any automatic checking feature in the Router.
Where are we now?

Ethernet connection pismo- G4 to read disk warrior

I have a pismo G3, OS 10.3.9 that is not reading the correct date and time. I ran the disk utility and corrected the disk permissions. But when I went to start up from the OS disk to correct the disk, my pb would not read the disk. Nor start up from it. Same thing for my DiskWarrior disk.
I would like to connect my pismo to my G4 desktop and have the desktop read my disks and repair the pismo. I know I can do this with a firewire connection, but I left that cable at work, and it's not possible for me to buy another here at home. I have an ethernet crossover cable that I can use, but nothing in the documents I read here at apple explain how I can get the G4 to help repair my pismo disk via ethernet. Can anyone advise me?
Thanks,
Sheila

Sorry, but I do not know of any way to use the Ethernet connection to get the Pismo in "Target Disk Mode" (which is what the Firewire connection does). Older Macs used to be able to go into Target Disk Mode using the SCSI port, but never heard of Ethernet. If the Pismo is not working well enough to boot up and configure as a file server then the Ethernet connection is pretty much useless. However, while I've never done it, I think it might be possible to do a boot from a networked computer that is acting as a file server. Sorry I don't know exactly how it must be configured (e.g., OS X server or just OS X with the boot volume shared), but I suspect it needs some sort of special software to act as a remote boot device.
What you can try doing is a reset of your parameter RAM, though. It sounds like the PRAM battery has finally failed in the Pismo (date and time loss is one symptom). It could be that the PRAM content is so badly muddled that it cannot find the startup disk. Hold down the Cmd-Option-P-R keys (yes, it does take 2 hands) as soon as you can after pressing the Pismo power button - it must be within a couple seconds - and continue holding them down until you hear the computer reboot at least 2 times (some people do it for 4 or 5 chime sequences). That will put PRAM back to factory defaults and (hopefully) allow you to boot from your normal startup volume.
Note that as long as you leave the Pismo plugged into an AC power supply, it should hopefully hold the new configuration. So you could also then try booting up into single-user mode (hold down Command and letter "S" as soon as you power on) and doing a /sbin/fsck -yf to repair your startup disk (which works if only you have OS 10 installed on it). Another thing to try is to hold down the Option key right after powering on to bring up the screen that will select your bootup volume. If you have your G4 set to target disk mode with a Firewire cable, you can actually boot from its hard drive. But you do need the Firewire cable, which you say you cannot get. Hmmm - if you have configured your G4 to share your startup volume via Ethernet, this MIGHT be a way to get to its hard disk to boot up, but I can't say for sure.

High CPU load kills ethernet connection

Short spikes in CPU load (MenuMeters installed) are constantly killing my internet connection.
I use an ethernet connection with a cable modem (Motorola SB 4200 E) and have a MB 2 CD, 2 GB of RAM and OS X 10.4.9.
After the ethernet connection is killed, only a complete re-start can fix the problem (and today alone I had to do something like 15 of them already).
These sudden spikes in CPU load can be caused by all different kinds of activity, e.g.
1.) playing back video files which my machine has problems dealing with (like .mkv files),
2.) playing back 'regular' .avi files,
3.) browsing the net (Camino, Safari, Opera, Firefox) and displaying flash content (just watching something on youtube creates a CPU load which kills the connection regularly),
4.) any kind of activity which asks a high CPU load in general.
It seems that the problem is caused by the CPU load in general, not by any particular application which causes the high workload.
What I have tried:
1.) PRAM reset
2.) Apple Hardware Test (extended, loop)
3.) de-installed Flash player
4.) created a new user (admin)
5.) made a clean 10.4.11 install on an external USB drive and booted from there
6.) used Airport instead of the ethernet/cable modem
7.) checked system temperatures (which are ok)
8.) changed/exchanged/checked the RAM
9.) made enough free disk space on my HD (15 GB)
10.) repaired disk permissions
but to no avail.
Any help would be very much appreciated (since I'm ready to get a MS machine and wave my Mac good bye).
Kind regards
FC

Never mind, problem solved. When I retunred to the Network tab the message had changed to "connected, no IP address" so I got that from the WiFi tab and configured the Ethernet manually. Have a nice day @:-)#

How do I use my iBook with a hotel's ethernet connection?

When a hotel just has an ethernet connection, I can never come up with the right configuration to access it. Does anyone have the procedure?

Plug in the ethernet.
(Turn on/log in your iBook)
Open browser
Go to a website.
It should now load.
If for some reason the obvious is not working, do this.
Open System preferences.
Click Network
Now at the top pull down the menu and select network status.
There should now be a line that says ethernet.
In that line it should say "connected, your IP address is x." If it does not say that it is connected, what does the error say?

We have an airport extreme wifi in house, but also want to set up a hardwired ethernet connection for gaming and streaming of netflix. The computer only sees one or the other not both at same time.

We have a new iMac 2.9ghz and are running an airport extreme set up in house with several express entenders. The problem is that our son is streaming netflix and doing on line gaming and hogging all the band width. Time Warner tech suggested a hard wired ethernet connection to computer base sattion next to computer so that it can have direct conenction to internet. After much fishing of wire the connection worked great, but the wifi connection for the house is gone. I unplugged the ethernet connection and everything is fine. I read the articles about adjusting network preferences, but the issue seems to be in the extreme not in the computer. the connection goes from cable modem to extreme, from extreme to house and to hard wired conenction to other computer. Do we need a splitter before the extreme?

No. Something else is going on.
Your son may be hogging all the bandwidth but your wireless network should never simply disappear. Moreover, if your son isn't doing anything the available bandwidth for other devices should remain unaffected.
I suspect that something is miswired, and from what you describe I suspect that link is between the Extreme and the "other computer".
The way to accomplish what you propose is
Modem > Ethernet cable to Extreme's WAN port
Extreme's LAN ports > wired Ethernet devices.
There should be nothing but an Ethernet cable linking an Extreme LAN port and any other wired device. If you run out of available LAN ports on the Extreme, you need to by an "Ethernet switch" - they are not expensive, but don't call it a "splitter" or you will only confuse yourself. The switch would be connected to one of the Extreme's LAN ports, and you would connect additional devices to it. You can also use one of your Expresses for that purpose, assuming it is the current generation model with two Ethernet ports.

Multiple ethernet connections on a WDS with AirPort Express?

Going through the AirPort Admin Utility and Airport Setup Assistant, and the various pdf manuals, the only way I can seem to create a WDS is for each device to be a wireless bridge.
Even setting it up initially as a WDS that connects using AirPort (default config from the setup assistant), then changing it to connect via Ethernet completely broke the bridging and caused much mayhem.
I'd prefer to set up the new Express device as a wired bridge, as I have a spare ethernet connection on the same subnet. I presume this would lessen the overhead needed by the WDS in general and would speed up the overall performance slightly.
Does anybody have any clue how to go about this, if it is possible? I bet it's something small and stupid I've overlooked.
Going back about ten pages in this forum didn't seem to cover this subject, so I apologize if I'm bringing up this subject AGAIN. Oh yeah, and all Airport Express devices involved are on firmware v6.3
Mac OS X (10.4.8)

Disable the distribution of IP Address on the Express setup.
You don't mention if you are using Airport Express or Extreme for your Main Base. If so then here is the link.
http://docs.info.apple.com/article.html?artnum=107454
If you are using a 3rd party Router as your Main Base then you will need to check out one of these 2 links and remember not all 3rd party routers are capable of WDS setup.

How do I use my ethernet connection for printing on my LAN and use my Wifi on a different router and ISP to connect to the internet?

I'm in a small office, and I have to use my ethernet connection to connect to the networked copier to be able to print, but connection to which I hooked my Time Capsule is literally 20x faster when connecting to the internet.
How can I tell the computer to use the ethernet connection to print, while everything else should go through wifi?
I have been manually going back and forth changing the order in Network Preferences between ethernet and Wifi, but I'm know there must be an easier way. Thanks for your help!

A packet going to Apple is not local. It is going to 17.149.160.49 -- So it is sent to the topmost working connection to be Routed and sent to the Internet.
A packet going to a local computer or other device that is on the same subnet (has an IP address very close to the topmost IP Address of your computer) gets sent out that port as well, but is sent directly to that computer on the local subnet, since no Routing [changing of Addresses} is needed.
A packet going to a local computer or Printer or Network Attached Storage device that is not on the topmost subnet, but is on a secondary subnet such as the second network connection would be sent directly to that computer, since no Routing is needed.
I do not understand why two Routers have the same IP Address if they are not cross-connected. That makes everything very difficult when it should be simple.

How do I reduce the MTU on my Airport Extreme Ethernet connection?

Hi there,
Is it possible to reduce the MTU on the Ethernet connection inside the Airport Extreme Base station. I was having trouble accessing some websites, but was able to fix it on a direct ethernet connection by reducting the MTU setting to below 1500. However, when I connect wirelessly ( I have a DSL modem connected to the WAN port of an Airport Extreme Base station), I still have the same problem, but there seems to be nowhere in the Admin utility where I can reduce the MTU for the connection.
Anyone know a work around for this?
Thanks

Don't know if this will help, but if you use cocktail there is a place under "Network" where you can change the mtu setting for the machine you are using. I also remember seeing some info on this in the unix support group here in the forums.

How do I extend an existing wireless network with a 2nd time capsule? I want to tether them with a gigabit ethernet connection.

I am having trouble with extending a wireless network using 2 timecapsules (1 is 1 terrbyte hdd, the other has a 2TB HDD.) The first one is connected to the WAN (cable modem) and our LAN. I would like to connect the 2nd one to the ethernet LAN and have it 'rebroadcast' the 1st ones wireless n network in order to expand the overall range of the network. Your help is very much appreciated.

Suggest that you download and install the much more useful AirPort Utility 5.6 for Mac OS X Lion.
I assume that Time Capsule 1 is operating correctly at this time.
Open Macintosh HD > Applications > Utilities > AirPort Utility 5.6
Select Time Capsule 1 and click Manual Setup
Click the Wireless tab below the row of icons and make a note of each of the setttings on this Wireless page.
Make sure that the Ethernet cable is connected to the WAN "O" port on Time Capsule 2.
Open up AirPort Utility and select Time Capsule 2 and click Manual Setup
Click the Wireless tab below the icons and enter the exact same settings that you wrote down for Time Capsule 1
Click the Internet icon, then click the Internet Connection tab
Make sure that the settings look like this:
Connect Using = Ethernet
Connection Sharing = Off (Bridge Mode)
Click Update and allow 25-30 seconds for Time Capsule 2 to restart to a green light
Very important......perform a power cycle of the entire network as follows:
Power off every device in any order that you wish
Wait a minute
Power up the modem and let it run for minute by itself
Power up Time Capsule 1 the same way
Power up Time Capsule 2 the same way
Continue starting devices one at a time the same way until the entire network is back up

Is there a way to turn the wireless capabilities off on an AirPort Express? I have an AirPort Extreme as my main router and use the express to just extend it. I only really want to you use the express for hard ethernet connections

Is there a way to turn the wireless capabilities off on an AirPort Express? I have an AirPort Extreme as my main router and use the express to just extend it. I only really want to you use the express for hard ethernet connections. For whatever reason when I have my express extend my wifi at home the download speed from just the express is absolutely terrible, drops to about 1.5 mb compared to when it's on the extremes part of the network the speed goes up to 50-75mb. These terrible download speed really only affects the iPhones as my MacBook Pro usually gets the good speed no matter where it is. I don't believe there is anything wrong with my phone because if I am in the part of the house that uses just the extreme the download speeds on the iphone goes up to 50-75mb. As a note I have an AirPort Extreme on the top floor of my house (second floor) that's where my modem is located. On the first floor that's where one airport express is located. I also have another airport express in the basement that is accessed by my landlord. Any thoughts on how to fix this would be helpful.

It appears that your networking goals with the AirPort Express is to use it as a wireless Ethernet bridge instead of using it to extend the wireless range of your AirPort Extreme. The latter requires that the Express Wi-Fi radios be enabled.
If you intended to use the Express as a wireless bridge, you just need to reconfigure it to "Join a wireless" network instead of "Extend a wireless network."
For whatever reason when I have my express extend my wifi at home the download speed from just the express is absolutely terrible, drops to about 1.5 mb compared to when it's on the extremes part of the network the speed goes up to 50-75mb.
In an extended network, the placement of the extending base station is critical as it can only extend the wireless network at the bandwidth at which it receives it.
Please check out the following AirPort User Tip for details on optimal base station placement.

How can I use my ipad in a hotel that only has ethernet connections. The apple store clerk told me that I can't use airport express unless I also have a computer with me in the hotel.

How can I use my Ipad in a hotel that only has ethernet connections? The Apple store clerk told me that travel express won't work in my hotel unless I also have a computer.

The issue with the Airport Express (or any of the Apple routers) is that you need the Airport Utility to configure it. Airport Utility works on OSX and Windows, but not on the iPad (or iPhone or iPod Touch.) It will work, if you can preconfigure the Airport correctly ahead of time, but you'd be stuck if you did need to reconfigure while at the hotel.
You can use most any other router that is configured with a web page, which means you have a chance of configuring with Safari on the iPad. If you want something somewhat portable, I use a "travel router" made by D-Link. The current model is the DAP-1350. Other companies make similar travel routers, but I have no experience with the others.
