Can't connect via Ethernet

I have an iMac G5 iSight and have been using Airport successfully to connect to the Internet via a DW6000 satellite modem. Since I have now retired and will no longer be using a Powerbook, I decided to stop using Airport and attempted to connect via a hardwired cable from the iMac to the Modem. It refuses to work. The settings show that it has acquired the correct address from my provider and is properly connected to Direcway via DHCP. I have rebooted the modem and the computer, renewed the DHCP licence all to no avail. The information says that although the Ethernet port is active, it has an internal address and cannot be connected to the Internet.
By the way, I was able to connect to the Internet via Airport or Ethernet with my G4 Powerbook. But I can't do it via Ethernet with the iMac.
What can I do to get this working?
Griff

Problem resolved!
I don't know what the problem was. I just tried again. This time I did not reboot the computer. I shut down the modem, attached the Ethernet cable and fired it up again and this time I was connected!
So I really don't have an answer except that it just decided to start working.

Officejet 6500A Plus w/ Windows XP on Desktop, Windows7 on Laptop. Can I connect Via Ethernet & WIFI SIMULTEANOUSLY?

No. You can have one or the other. How the printer connects does not have to match how the computers connect.

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.

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:

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

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

i rebooted the firewall and it worked.

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.)

Arg! Airport Extreme to Extreme- Can't Connect via ethernet

Hello- Arg! Frustrated and can't figure out what's going on.
Goal: Wirelessly connect an airport extreme to another airport extreme and use the 2nd Extreme as a local wired hub.
Problem: Everything works fine, but any machine that is hooked up to the 2nd extreme isn't getting a DHCP assigned and can't see it. But wireless can see it and works great.
Setup: (here goes)
- Airport extreme 1 (AE1) is hooked up to a comcast cable modem. Works great
- Airport extreme 2 (AE2) has been configured to wirelessly join AE1- This also works great.
- 2 Mac pros are connected to AE2 via ethernet cable
visual example:
(comcast) - (AE1) ~~ (AE2) - Mac pros "~" = wireless, "-" = wired
I've tried different machines and cables... no luck. If I reset AE2, they can all connect.
What am I doing wrong here... seems like ethernet is being disabled.
All AE have been updated and along with computer software. All wireless works fine.
Thanks!
Message was edited by: mr.bill

Got it... Instead of joining, I had to select extend and ensure that AE1 had extend network enabled. Seems to be working now. Sweet!

Can't connect via Ethernet to Express. Airtunes works, no ethernet though

Hi,
I'm having trouble connecting an old iMac g4 without an Airport Card to an Express over Ethernet. My Extreme is running great, the Express says it is connected to it with WPA/WPA2 (green light and all) but can't connect it over Ethernet to the iMac for whatever reason.
I'm connecting to the main base station on a MacBook just fine.
Thanks in advance to whoever can help with this

Hi,
Thanks for your response. I've found a very odd, counterituitive, shouldn't work, kind of fix. I HOPE it stays fixed...
When working in the Airport Utility, devices will not always show up. If you click in the upper right corner of your screen where the Airport signal is and select the network, you can force the utility to see it. (Think of this as the doctor saying "Nope, can't find your kidney to do surgery" and you pointing out "Hey doc it's right there!")
After a long wait, you can do the same for your Express, if it pops up in that same menu (typically with an odd number attached to it perhaps the MAC address.)
So essentially, the Airport Utility has to be kicked around a bit by the select a network menu. Odd I know. Hope this helps someone who's had similar problems.

Can't connect via ethernet cable to Fios on my iMac

Well, went from cable because I was only getting an upload and download speed of 19 Mbps and was promised close to 50/50 if I went to Fios. Decided to go for it and installation took a full day.
During set up we found I could only connect my iMac 27" Silver desktop via Airport or wireless. For some reason even though my preferences on the mac was showing that I was connected both wireless and ethernet, if I select the ethernet option it doesn't work at all. Bad part is that wireless connection is about the same I was getting on cable or 19-20 Mbps up and down.
The service tech came out and told me he wasn't a mac guy, but plugged his PC laptop into the router and he was getting 49 mbps. I have a PC also on my network and it is working fine and much faster then the mac.
I have spent many hours trying to understand why I am having this issue. Tech guys told me he isn't a Mac guy and it has to be a Mac problem not a router or Fios problem. This is always the excuse when companies have no clue what to do.
So now that Verizon is on strike I can't get any support at all. I have a 30 day guarantee and may want to cancel and uninstall Fios and go back to cable where the tech support is excellent and the only issue I had was the internet speed.
There is no reason to have Fios if I am getting less service for the same money. Frankly, I have taken videos showing how slow it is. On many sites or times of the day, it won't connect to a URL at all and it will begin, then hang up and I have to keep trying to reload the url until I can get it to go. This is totally unacceptable and frustrating.
Does anyone have any real answers to this problem? I see others on a Mac also have this same problem. Some blame the router, others blame the settings...I am lost and use my computer for business and need reliable service.
I can't even get anyone on the phone at Verizon to either extend the 30 day guarantee until we resolve this problem or cancel the service and reinstall cable.

The Mac should be plug and play with the Ethernet connection, and you shouldn't need to play with anything at all. Does the ActionTec's Ethernet lights indicate a link when you connect your Mac to the router? Does the Mac's NIC (if it has lights on it) indicate a connection? Does the Mac indicate that it has a valid IP address while it is connected to the router using only Ethernet? What version of OS X are you running?

Can multiple Airport Expresses be connected via ethernet to an Airport Extreme to extend a single WiFi Network?

I am a big fan of both the Airport Extreme and Airport Express. In my work environment, I need to create a good quality single wireless network around 2 large aircraft hangars and some offices at the perimeters. We have a good quality wired Cat5e ethernet network extended between the buildings and offices now. Is this possible and does it seem like a good practical solution? I think that 4 or 5 Airport expresses would easily provide good wireless coverage in the needed areas.

Can multiple AirPort Expresses be connected via ethernet to an AirPort Extreme to extend a single WiFi Network?
Yes, this will work just fine as long as any individual Ethernet cable run will not exceed much over 330 feet or about 100 meters.

HT4356 Can I use a 'pc' network printer connected via ethernet to the home wifi network ?

Can I use a 'pc' network printer connected via ethernet to the home wifi network ?
or must the printer I want to use also have a wifi connection ?
I have a home network using ethernet connected devices to a router, also attached to th erouter is a WiFi unit. We are using the WiFi unit to connect to the network and hence to the big wide WWW. We now want to print from our IPads pereferable to our netowk connected HP Officejet Pro 8500 A909a series. (not the wireless model).
I was using the HP ePrint app to print from the Ipad, but I do not fully understand how this works. It seems that you must use the app to do the printing which is fine for basic email and photos, but I can not access the drawing package I have, and want to print from it. Please what is it that I do not understand.

You must use an airprint printer directly connected to wifi through it's own wifi card.

Can you use Time Capsule as a print server for printers connected via Ethernet or wirelessly?

Can you use Time Capsule as a print server for printers connected via Ethernet or wirelessly?
I know that it works marvelous for printers connected via USB, but I'd like to know if you can use it as a more general print server.

No, you can't, but what do you expect to gain by doing so?
The main advantage of the print server is to provide multi-user network access to a printer that typically only supports a single connection. Since, by definition, your printer already has a network connection and can be used by multiple users.

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.
