System prefs says I am connected via ethernet but applications say I'm not.

I suddenly lost the connection to the internet on my G3 333 MHz imac.
The network prefs. say I am connected to the internet via my ethernet but when I open an application like software update of safari they say I have no connection to the internet.
I tried restarting my cable modem and restarting my airport that I am running my ethernet cable out of and I restarted the computer and it still shows the same thing.
I plugged the ethernet cable into my laptop and I connect no problem.
I repaired the permissions and tried creating a new location with no luck.
imac 333 MHz G3 160MB memory Mac OS X (10.3.9)

I have the EXACT same problem. I can't figure it out to save my life!!

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.

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just cancelling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.

Try it and good luck. You have nothing more to lose if it doesn't work for you.

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.

Connect via ethernet but wireless for internet

I don't know why, but my apple tv seems to have forgotten how to connect to the internet and I can't make it remember, lol. Now I will stress, this used to work, and I don't know why it suddenly doesn't work anymore...
Basically I have wireless set up at home for the internet. However, I connect to my apple tv via direct ethernet cable between my imac and the apple tv itself. I have set up internet sharing in preferences to share my airport connection over ethernet, which my apple tv used to be able to use ok to connect to the itunes store/you tube, etc. However, it now can't. I had some trouble with it this morning where it wouldn't connect to the ethernet network at all, although it now does. However, it no longer uses the iMac as it's router and I can't seem to figure out why. Can anyone help?
Thanks!

Can connect via Ethernet but not via AirPort

I'm having some problems using my AirPort in Germany. I can connect just fine using an Ethernet cable direct from the modem (NETGEAR DG632B) but when I have plug the Ethernet cable into the AirPort I can't connect. I beleive it has to do with PPoE settings, which I am not really familiar with.
There are three spots I can enter my account info. 1, on the modem itself via Safari; 2, on the AirPort via AirPort Admin Utility; 3, on the Mac via Network Preferences. I have input my PPoE username/password into the modem while directly connected. I would tend to think that this shoudl be it and that everywhere on the LAN side of the modem would be able to utilize that account. The NETGEAR settings page shows the ADSL port Network Type as PPPOE and the LAN port as DHCP, so I have attempted to set up my AirPort and Network prefs using DHCP. That leads to "You are not connected to the Internet. Safari can’t open the page “http://www.google.com/” because your computer isn’t connected to the Internet." Network Diagnostics shows green at AirPort, AirPort Settings, Network Settings and ISP. It initially shows yellow at Internet and Server which lead to "Failed" on both. Network Diagnostics then asks me to choose my network port configuration (Built-in Ethernet, Internal Modem, Airport,Other). I select AirPort and select my AirPort network. Then all the Status lights except for AirPort turn red and asks if I use a DSL or cable model. I select yes, it asks me to restart the device, I do, it asks if I can restart any other devices, I select no. At that point Network Diagnostics says it is unable to connect to the Internet.
I have down-graded to Airport Firmware v5.5.1 as some have advised. No change. I'm running MacOS 10.4.6
My AirPort is just fine as I can use it to set up a LAN with no problem. I even pulled out my old Graphite base station and tried it. Same thing.
I have tried putting my PPPoE account info into my AirPort, my Network prefs both individually and both at the same time. Nothing. Is there something that I'm missing?

You'll need to connect your modem to your AEBS WAN port, configure your AEBS with the Airport Admin Utility, setting up the PPOE to properly log into your modem connection.
You should set up your mac to us DHCP (not PPOE).
THis should allow you to use either the ethernet port or wireless from your AEBS.
I hope this helps!

Mac Pro Can't See MS-DOS Fat32 HD on PowerPC G4 Connected Via Ethernet, But Can See Its Mac HDs

I have a Mac Pro (aluminum Late 2010) running 10.9.5 connected to a PowerPC G4 running 10.4.11 via a ethernet cable running from the 2nd ethernet jack on the Mac Pro to the ethernet jack on the PowerPC G4.
I've connected to the PowerPC G4 via the Power Mac's network connection and I am able to see and interact with two of the G4's HDs, which have 10.4 and 10.5 installed. The G4 also has a third blank HD which is formatted in MS-DOS Fat32 format which I can see on the G4's desktop. I can't however, see the Fat32 drive on my Mac Pro's Network window, just the two Mac formatted drives.
Is there anyway to see the G4's Fat32 drive on the Mac Pro?

That did the trick! Thank You!
Under 10.4.11 System Preferences:
Check "Windows Sharing".
Choose account to share.
Enter your account password.
Refresh window on the Mac Pro and it shows up

IMac connected via ethernet, but no internet

I'm running Snow Leopard on an iMac (model identifier iMac 4,1)
Two days ago it was working fine. Then yesterday, suddenly the internet wasn't working.
I run an ethernet cable onto a switch and from there connect various devices that are not usually on simultaneously. I have tried the cable going to the iMac on my laptop and the internet works. I also tried the cable that I'm currently using on my laptop on the iMac and that didn't work either.
Yesterday, I restarted it several times, tried resetting the PRAM, fixing permissions.... Eventually a 6th or so restart did the trick, but then when I turned it on today it went back to not working.
When I open the Network option from the System Preferences pane, it says the Ethernet is connected. Also, IPv4 is using DHCP and the DNS server is the same as the router number. No idea what that means, but if it helps...
It does say "Ethernet is currently active and has the IP address xxxxxxxxxxxx2.10" whereas the router number is xxxxxxxxxxxx2.1 Don't know if that has anything to do with it.
Anyone have any ideas?

Can connect via Ethernet but not on Airport

I am able to connect fine with Ethernet. Initially when I brought up Safari it launched the modem and I had to enter my ISP username and password. Then I was able to connect fine with Ethernet. My problem is that I cannot connect with Airport. I disconnect the Ethernet from my MacBook, then I turn on Airport. It detects the wireless modem. I select it. It connects fine, but no internet. I go to the System Preferences, Network. But find nothing wrong. Am I missing something ??? Please advise.

Hi,
You also might want to check that the AirPort doesnt have it selected to have the IP set manually. Always have this detected by DHCP. There should'nt be any problems there, if you are using the Ethernet cable.

Time capsule USB printer works when I connect via ethernet but not over wifi

I have a USB printer hooked up to my new Time Capsule. If I turn off my wifi and connect to the Time Capsule with an ethernet cable it works fine. When I try to do the same thing over wifi (even when I'm sitting next to it) it cant seem to make a solid connection. Most of the time it just says Printer Paused, but sometimes it will work, other times the printer just clicks, or starts but then stops. Other than that my wifi connection seeems pretty good.
Is there something with the settings with my older "08 MacBook and the newer Time Capsule?
Any help is very much appreciated,
Thanks

Very interesting one..
Did you upgrade install ML into the MB??
It sounds to me like it has corrupted the wireless drivers.. and I think you will need to do a clean install.
If you have internet working over wireless I see no reason for this to happen though.

My iPad 1 says it's connected to wifi but safari says can't open page cause not connected to the internet

Does anyone know why this is I've tried resetting but doesn't help?

Are you on a home or open network? Sometimes when you're in a hotel, for example, you may be 'on' the net but not allowed to access it until you agree to their terms.

APE only works when connected via ethernet

I have a new AirPort Extreme that I am trying to add to my existing network (an older APE base station and 2 Express) and no matter how I try to configure it, I can't get it to work without being connected with an ethernet cable (either to my MacBook Pro or to the other APE base station).
I also tried setting it up on its own with a new network and that wouldn't work either.
If it isn't plugged in, and I try to change the configuration, i get this error:
"AIRPORT UTILITY WAS UNABLE TO FIND YOUR BASE STATION AFTER RESTARTING.
The settings for this base station have been successfully updated, but there was a problem re-joining the wireless network or finding the base station. You may need to select your network from the AirPort menu and try again."
The amber light flashes, and it never shows up again. It doesn't matter if i unplug the APE, turn AirPort off and on, restart the utility, restart my mac... it won't ever show up unless I connect via ethernet, but as soon as i connect the ethernet cable, everything works fine.
Does this mean that there is something wrong with the APE, or is there something I'm doing wrong with my setup (I've tried the assisted setup and manual setup following the instructions in the "Designing Air Port Extreme 802.11n Networks" pdf)?

Yes. It's just the one APE that is a problem. The rest of the network is fine.
If I connect the new APE to the older APE with an ethernet cable, I can see it in AirPort utility and use AirPort Disks connected to it, too; but as soon as I unplug the ethernet cable, it can't get back on to the network and it no longer shows up in AirPort utility.

Apple TV (1G) doesn't appear in devices list when connected via ethernet

After upgrading to OS X Lion and iTunes 10.4 my Apple TV (1G) doesn't appear in the devices list when connected via ethernet. When I switch to wireless lan the device is shown and the sync process starts but can't copy the new films. The copy operation stops every time and sometines the device disappears from the list.
Despite of the upgrading of OS X and iTunes all the settings are unchanged.
Anyone an idea?

Since my last update, I've gathered more information. I'm almost certain this is not entirely a 10.7.1 issue, if an issue in 10.7.1 at all. 10.7.1 may have changed something that caused this issue to appear,but where I was having this problem weekly if not daily, I no longer have the problem. I changed routers. I was using a new D-Link Xtreme N Gigabit RouterDIR-655. This router was causing me pain with lock ups. I replaced it with a Cisco Linksys E4200. I have not had a lockup in over 2 months now and not one sync issue with Apple TV nor my new iPhones, which sync wireless to iTunes on my Mac Pro.
Thinking about how my network is wired leads me to believe the issue was in the router, or maybe a network communication change in 10.7.1 that the DIR-655 was not supporting correctly. My MacPro and a few other hardwired access points in my house go directly to the router. My AppleTV and Airport Extreme are connected to a Gigabit switch and the Gigabit switch is then connected to the router. I also turn off the wireless capabilities in my routers, as I prefer to let my Airport Extreme handle those duties. This all means my normal hardwired communication path from my Mac Pro to Apple TV was going through the router, to the switch, to the Airport Extreme and then to my AppleTV. My Apple TV is connected to the LAN port on the Airport extreme. By going wireless on the MacPro, I was bypassing the router altogether.
As I started out saying, since I replaced my router, my sync issues have also gone away. If your having Apple TV sync issues, you might want to look at the router as well. Also, while I can’t remember the exact settings, I had opened up or enabled UPnP and other router settings in the DIR-655 to see if that would resolve the sync issues and it did not. In the end, I just spent the money and bought a new router and life is good now.
