Trouble connecting via Ethernet

At home I use Airport with a Time Capsule and a DSL connection. Recently I've tried to plug into the modems at friends' houses via Ethernet and haven't been able to get online. At one location it's a cable modem, the other DSL. I go to Network Preferences and try using "Automatic" as my location ... but no luck. I've tried using "Assist Me" but it always winds up telling me I need to check with the ISP and/or enter login info. However, my friends have told me other have just simply plugged their laptops in and immediately were connected. What could be wrong on my end?
Thanks in advance!

You don't say what ISP it is but typically ISPs like Comcast capture the mac address of the first device to connect to the modem. Any change in the device, such as you connecting your computer to the modem in place of your friend's will not result in a successful issuance of an ip address to your computer. You must power cycle the modem when you change the device connected to it.
The way around this is to connect a router to the modem. You can then connect your and your friend's computer to the router at the same time. Each will get onto the Internet without any need to power cycle the modem.

Trouble connecting via ethernet cable (again)

Please excuse that I already posted exactly this problem a few months ago. Now that I need the solution again my posts have unfortunately been deleted due to the 30-day expiration period.
I try to connect a XP notebbok to the AirPort Extreme by ethernet. The cable is correct, now I need the right numbers for the XP network settings.
IP-address: 10.0.1.2 (AirPort being 10.0.1.1
subnet: 255.255.255.0
DNS: ???
Someone posted a solution but I can't remeber. Your help would be once again very appreciated. Thank you.

IP address 10.0.1.201
subnet mask 255.255.255.0
router/gateway 10.0.1.1
DNS - try 10.0.1.1, or enter the actual IP addresses of your internet service providers domain name servers

Powerbook G4 can't connect via ethernet but connects via airport

We have a small office network connected to an Efficient Networks DSL router that's managed by our isp. The router has 4 ports and a linksys 8 port switch is connected to one of those ports. Another D-Link wireless router/switch is connected to another port.
2 i-macs connect without problem via ethernet cable. They are set to DHCP and get 192.xx private addresses. Both run 10.4.5. Another older imac running 9.2.2. also has no problems.
I recently purchased a powerbook G4 and it will not connect via ethernet to the Efficient networks router. At first it was connected to the linksys, so decided to connect it direct to the Efficient Networks router. With DHCP, it acquires a 169. internet address which is self generated (i.e. no real connection). I tried to give it a static private address (talking to the isp provider). They could see the powerbook but saw all zero's (presumable mac address). By the way the Powerbook works perfectly at home connected via ethernet cable to a D-Link router connected to a cable modem so it's not a physical problem. I even checked the ethernet cable I used in the office with another computer - no problem.
When I switch to airport in the office, the powerbook connects to the network and the internet. I get some strange warning messages showing the server's and the router's private ip addresses. I click ok, and the powerbook finds an unassigned private ip address. It's the only way it will work, but it causes problems, because I can't connect to one of the network printers. Speed also isn't great.
Can anyone give me advise how to proceed. I am no expert on this stuff so keep it as simple as possible.
Tks

Tim,
Thanks for your help. Here's what I've done before reading your e-mail. The D-Link DI-524 wireless router is connected to the Effiicent Neworks DSL router as you mentioned. One ethernet port of the EFF.Net. router is connected to the WAN port of the DI-514.
Because I have a D-Link router at home which works flawlessly with my powerbook, I decided to connect the ethernet cable of the powerbook to the D-Link which has 4 ethernet ports. Lo and behold, the powerbook acquired a private ip address and connected to the LAN and internet!
When I connected the powerbook direct to the Efficient Networks router, it could not communicate. I believe that there must be some software incompatibility between the powerbook and the Efficient Networks router. By connecting to the D-Link, the D-Link assigned an ip address to the powerbook, and it could connect to the server, lan, etc..
Only problem is that I have a Brother network printer that cannot connect to the powerbook. My powerbook cannot find it on the network. Because there is a linksys switch connected to the efficient networks router's third ethernet port, maybe as you said, going through the D-Link via DHCP (when the Linksys is also acting as a DHCP server, might cause this type of problem. What do you think?
As a final note, other imac G5's connected to the linksys switch (which then connects to the Efficient Network's router) have no problem connecting to the lan or internet and have no problem connecting to any of the printers. When I put the powerbook on that switch, I could not connect to the internet - i.e. whether connecting via the lynksys switch or direct with the efficient networks router - same results: no internet connection whether manually or via DHCP.
So the imac G5 has no problem with the efficient networks router but the powerbook G4 hits a brick wall. The G4 likes the D-Link router. I am concerned (and I will have to check this) that if I turn off the dhcp server feature from the D-Link, that whatever software issue crops up between the powerbook and the Efficient Networks router, will rise up again, because the D-Link will act like a simple switch (just like my linksys switch), and we'll be back to square zero. In any case, no harm in trying. This may be the cause of the Powerbook not seeing that Brother printer (even though it sees another printer and other macs).
Having spent hours reading about network problems, I think it's safe to say that macs have problems with certain routers. Why a G5 works and a powerbook G4 doesn't is beyond me, but clearly software must play a role.

I have a Airport network at home with a Time capsule connected via ethernet cable to modem. Also the network is extended wirelessley with an Airport Extreme. I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme. Can my network operate properly to extend the network with both a wireless and wired extend functionallity?

I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme.
Excellent plan.
Can my network operate properly to extend the network with both a wireless and wired extend functionallity?
Yes, but don't get confused about the second AirPort Extreme, as it would not be configured to "extend" a wireless network.....it would be configured to "create a wireless network" using the same wireless network name, security settings and password as the Time Capsule network. Configure the second Extreme in Bridge Mode.
This Apple support document will show you how to hookup and configure the second AirPort Extreme:

I just purchased the 2TB TC and set it up on bridge mode to my att verse which is connected via ethernet cable. The TC is continually blinking amber and an error message states that a wireless network cannot be found but the uverse is functioning great. The network name I assigned to the TC is also not appearing among available networks. How do I remedy this, please?

What OS on the computer you are using to setup the TC?
Did you turn on ipv6 for wireless to link-local... this is essential for network access now??
Try power cycling the network.. start up in correct order.. uverse.. 2min wait.. TC.. 2min wait.. computer.
No luck factory reset and start over. Use ethernet cable as well to the computer to help it.
No luck I can show you manual method.

I have an HP LaserJet 8150N that I am trying to get connected via ethernet cable directly to my iMac. I always had this printer connected via a network so I don't know if I am able to connect directly with a cable since it is a network printer.

I have an HP LaserJet 8150N that I use for my work and I have had this printer for ever and it is one heck of a work horse! I am trying to get it connected via ethernet cable directly to my iMac. I always had this printer connected via a network so I don't know if I am able to connect directly with a cable since it is a network printer. I have tried to reconfigure the printer using the JetDirect menu giving it a new IP address but still no luck. If anyone could help me through this issue I would appreciate it.

Second, seeing "connecting" and connection failed is normal. You must click on "Connect As" in the Finder window and then enter the username and password for the admin account on the other computer. That should fix things.
Thanks for responding.
When does clicking on "Connect As" happen in the process above?
After step six? Seven?
After the connection has failed?
Is this the FInder window that shows the icon of the computer you want to copy the file from?
You should see "Connect As" in the Finder near the top right of the window as shown below:

IBook G4 Can't connect via Ethernet?

While we were away lightning took out several devices. Among them was the Airport Extreme Base Station and the cable modem. The modem has been replaced. I have an iMacG5 and an iBookG4 both running 10.4.11. The iMac can establish a connection via Ethernet (all this happened yesterday so I have yet to replace the Airport). The laptop apparently won't accept an IP address from the router/modem and won't connect to the internet.
I did see a message saying that my network settings had been changed by another application but don't know if this figures in the mix.
Anyone have any ideas how I ought to approach getting the iBook back online?

I think you ran across the security update bug in 10.4.11 the deals with an ethernet connection. Here is the workaround:

Can't connect via ethernet after iBook wakes up from sleep

I'm running 10.4.0 on a 1.33 GHz G4 iBook. Since buying the computer in 2005, I've been connecting to the internet in various locations via AirPort, though I have hooked my iBook up to ethernet connections in the past and had no problems.
Recently I moved to a university where I must connect via ethernet, as the wireless network doesn't extend to the areas where I do most of my work. I bought a new cable. Much of the time, my connection is fine. But frequently I am unable to connect to the internet at all via ethernet, and I've noticed that it's always after I've woken the computer up from sleep. I've tried various ridiculous "kick the car and maybe it will start" techniques like unplugging the cable at both ends and waiting, restarting five or six times in a row, etc., and it starts connecting eventually, but I have NO idea why or why not. When I check my network preferences, I get the message "Built-in Ethernet is currently active and has the IP address [xxx.xxx.x.xxx]. You are connected to the Internet via Built-In Ethernet." But I'm not. What's going on here?

Sorry, meant to indicate an IP address without giving the exact numbers, and it came up as an HTTP address. My network connections system preference panel indicates a normal IP address. (And it's not self-assigned.)

Airport extreme won't connect via Ethernet to BT homeHub v2.0

Hi
here's what I want to do:
1. Homehub is connected to the phoneline and will provide a b/g network for my iphone/xbox/laptop1
2. I want to connect my airport extreme to this (from what I can tell this must be done through an ethernet cable) so that I can have a separate N network which only 1 laptop will connect to.
So the problem I have is that no matter what options I select in the airport extreme when it's connected via ethernet it tells me that nothing is connected to the Ethernet WAN port. I've tried two different cables different ports on the back of the hub etc. nothing works. Every time I search google or forums for an answer people just write "connected it via ethernet and it works great" but there's no guide to what settings to use that I can see.
Can someone please help me with some sort of noob guide to get this setup how I've stated?
Many thanks in advance

Hey Bob
thanks fro the quick response. I have actually tried exactly that but it still flashes orange at me I'm suspicious that the AE may have a fault because during the setup (i can't remember the exact steps) but I got the AE updated and it complained that it could read from the AE (error code was 10057). Googling this does thow up a couple of solutions which I haven't tried.
so my steps should be:
Factory Reset the AE
setup as join existing network
join via ethernet to create a 2nd network
connect up the cable to the WAN port and the Lan of the Hub
change to bridge mode.
One thing I did notice (which may or may not be related) is the subnet mask on the AE says 255.255.0.0 when I set it up like this. However when I make it just join the network without trying to create a new one (which works) it sets it to 255.255.255.0 . the IP address also begins 192.168.1.* whereas in the other setup mode it is something different. Does that matter at all?
Thanks

Self-assigned IP !!! Can't connect via Ethernet

Hi all,
This is my problem:
- Now every time I connect my MBP (running 10.6.4) to my hall's network (staying on campus, in uni) it appears as "Self-assigned IP" and cannot connect to the internet for the Ethernet. It suddenly happened a few days ago and I have no clue what caused that
- Airport's working well
- Using Windows on Parallels and can still connect to the Internet despite that the Mac OS X does not at the same time, my friends' laptops have no problems as well
- Tried taking the IP, subnet mask, router( I suppose in Windows it is called Gateway ) details and typing in manually for the Ethernet settings on OSX but still cannot connect to the Internet. The status is Connected and "Ethernet is currently active and has the IP address 137.xxx.xx.xx."
- When I bring my laptop to a different place and connect via Ethernet, it works well, too, I just leave the setting to be "Using DHCP"
I've seen that lots of people have met this issue, also loads of advices have been given:
- reset the router ... --> I'm connecting to the hall's network, so that's impossible for me to do
- sudo ipfw list , sudo ipfw flush .. --> nothing changed afterwards
- someone suggested uninstalling any VMware --> tried uninstalling parallels desktop and the problem's still there
- untick the "Use Passive FTP Mode" for ethernet --> no difference
- Security settings ,Firewall --> firewall was even off when the issue 1st appeared
So ANY SUGGESTIONS PLEAAASSSSSSSSSEE !!!! I'm sick of having to turn to Windows just to access the internet
Thanks in advance

Apart from this one "*4) In the folder /Library/Preferences (not <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.* " , I've tried all the other ways suggested but didn't work.
I'm wondering what it means by "move" here :? Is that "copying and then delete the original" :??
A "move" operation is normally considered equivalent to (although more efficient) than "copying and delete the original". Just drag the folder out of its original folder and onto the Desktop, which will make it be no longer in its original folder.
I've seen others post advice about moving out specific files in that folder. That probably works just as well if not better (as it leaves in place other files not involved in networking), but I haven't spent the time to determine just which files should be moved.

Can't Connect Via Ethernet on new MacBook Pro

Hello,
I'm running into a frustrating problem and hoping someone can help.
I have a new MacBook Pro that won't connect via Ethernet. My old computer (Powerbook G4) with the same settings works flawlessly.
Details: under Network Settings I have Automatic/Using DHCP. When I click on Assist Me>Diagnostics, I get green lights all the way down (Built-In Ethernet, Network Settings, ISP, Internet, Server). The Diagnostics tool therefore proudly announces that my Internet connection is working correctly.
When I open Safari, however, it won't open any page. Using Ping I also get no responses.
When I plug the exact same ethernet cable into my Powerbook G4, everything works flawlessly. The only difference is that the IP address ends in .25 instead of .30 (I assume that's from the router assigning different IP addresses to the two computers.)
On another forum i read about someone having a problem with a long/lossy ethernet cable, but I just took my computer to the router and tried with a 2-foot ethernet cable. Same situation.
Help!
Thanks

Apple Tv (3rd generation) says it is connected (via ethernet), but none of the app, or channels, will work. They all say they are unvailable, try again later. The only thing that seems to work is iTunes. (I live in a dorm if that helps)

Its not properly connected to the network. Most school networks require login via webpage, which isn't possible as ATV has no browser. You will need to contact the IT dept or the network provider.

Connecting via Ethernet - backing up wirelessly

Hi
I have placed an order for Time Capsule but I have been wandering....
Is it possible to connect to the Time Capsule via Ethernet for the Internet Connection, whilst the back up takes place over wireless? Or does it mean if I connect via Ethernet, the back up and Internet connection will be via Ethernet? What I am concerned with it Lag on the network (same applies too for Wireless) and would like wireless back up whilst connecting via Ethernet to the Net.
Glenn

Or does it mean if I connect via Ethernet, the back up and Internet connection will be via Ethernet?
Yes

Out of the blue, my ITouch is unable to access my wireless network ONLY when my PC has been turned on (PC is connected via Ethernet cable, and has no wireless capability as far as I know). What gives? It works fine when the PC is off.

Does the iOS device connect to other networks?
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
I suspect a problem with your router. Try changing the security. First use no security as a test.
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
