MacBook can't connect Via Aiprport OR Ethernet.

Hi, I;m currently using ethernet though my PC. But the problem is:
1. When my Airport is connect to my X-Modem router. It has all green. But everyday it will stop with the internet but the light stays green. I have to Hard Reset it just to give it a chance to work.
2. When i plug the x-modem into my macbook via Ethernet, and try to access its HTML admin page. It never connects, but on my pc it does it instantly.
What can i do to fix it both?
Thanks. Mycael

You don't need to bump topics that are only an hour old. :P
What are the settings on your MB? Go in Sys Prefs -> Network and from the second drop down menu, select either Built-in Ethernet or AirPort. Have you selected DHCP in both the ethernet and AirPort settings?

Macbook can't connect via L2TP but can via PPTP. iPhone can connect to both

So I've been banging my head up against the wall for the better part of this morning trying to figure this out. Just as a note, I'm 3000 miles from my house and server, but I do have access to it for the time being via PPTP.
Before I left, I verified that I could connect with L2TP on my iphone's 3G network. I was also able to connect at the airport on my Macbook using L2TP. Sometime overnight something changed, and I can't figure out what. I noticed that my phone dropped it's VPN connection saying something like "the connection to the server dropped unexpectedly" or such. After that, I was unable to connect over L2TP on my macbook or iphone. On a whim I tried connecting over PPTP which worked! But only on my macbook. Again on a whim I tried to connect via L2TP on my iphone, and it worked?! I rinsed, lathered and repeated that process over and over again and confirmed that I could only connect over L2TP on my iPhone after connecting on my macbook over PPTP. Also, on my iphone, if I stored the password it wouldn't authenticate (probably not related).
As of this moment I am connected using L2TP on my iphone for the last hour, using it to successfully stream Pandora across US borders, but can't sustain a PPTP connection on my macbook for longer than 10 mins. And I still can't connect over L2TP. So that said here are the client and server logs (ips, domains and usernames masked....) Server and clients are in different timezones:

I'm having similar issues but not much luck getting any answers. I made a similar post here - maybe something in there will help you.
One thing I have been able to pinpoint is that the MobileMe Back To My Mac service was causing quite a few issues with being able to connect to the VPN. Once I turn off the service, connection seems to work fine. Although, once I'm connected, I cannot access file sharing. Still waiting for some answers on that.

Can't connect via Built-in ethernet

Can connect to internet via AirPort, but not by Built-in Ethernet. Network status says "The cable for the Built-in Ethernet is not plugged in". BUT it is and it is live because I have plugged it into another computer and it works fine. How do I check out the MAC hardware. Modem light for LAN Ethernet is on and blinks when cable is connected to the MAC. When I do the network diagnostics, there is a red light for the Built-in Ethernet.

Can't Connect Via Wired Ethernet Broadband Connection

Replaced a Westell 7500 with a DSL-N10 because of constant disconnects. The Westell had no problem connecting via the wired ethernet broadband connection which I switch to when I need to improve buffering for videos. The DSL-N10 won't connect and reports "Error 651 Modem reported a problem". I reconnected the Westell to determine if there was a problem but it connected to the wired connection immediately. Question is do I need to change or add a setting in the DSL-N10 to get a wired connection or is this something I need to conract Verizon support about?

D-Link wireless + Cable Internet:: can't connect via AirPort

Just got my service changed from DSL to Cable and can't connect via wireless (but can with an Ethernet cable). Have tried the Wi Router settings to no avail. Any ideas? I think I might not be doing some setting in the comp correctly. Please help. Router is D-Link DIR-625.

Did you open Airport and see if you see the wireless router? If you can see it, you can select it and then make sure it is set up properly in networks in the system prefs.

Can't connect via PPPoE in menu bar

Hello,
After not touching my Network Configuration settings for like three years, a glitch in my Unison 1.8.1 newsreader prompted me to go in to check, but I then encountered the prompt that has been afflicting lots of people: "Network settings have been changed by another application."
So after some research here and via Google, I deleted /Library/Preferences/com.apple.networkConfig.plist and restarted the computer with the file still in the trash.
I then manually reentered my ISP Network Configuration info (TCP/IP and PPPoE, as I use ADSL), but since then, I have only been able to connect via the Internet Connect program, rather than my preferred method that I've always used of connecting by using the PPPoE drop-down menu "Connect" command in the menu bar in the upper-right-hand corner of the screen.
Going back to System Preferences' Network Configuration, showing the Built-in Ethernet's PPPoE panel, the "Show PPPoE status in menu bar" box remains checked, and indeed does display in the menu bar, however, only with a functioning "Disconnect" command -- NOT the "Connect" command, whose functionality I am seeking to restore.
I realize this is more of a cosmetic problem, as I can still connect via the Internet Connect program, but would appreciate any tips for restoring the functionality of the PPPoE drop-down menu "Connect" command in the menu bar. Thanks in advance!

Can you connect via thunderbolt a mac book air 13" (2013) and a imac 21" (2013) together, using the iMac 21" as a 2nd screen

Can you connect via thunderbolt a mac book air 13" (2013) and a imac 21" (2013) together, using the iMac 21" as a 2nd screen

Welcome to Apple Support Communities
Of course. As both have Thunderbolt, it's as simple as buying a Thunderbolt cable, connect them and press Command and F2 keys on the iMac, so the iMac will be used as an external display for the MacBook Air. If you want more information, see > http://support.apple.com/kb/PH11302

I have an iMac running OS X 10.8.3 and have connected an Epson Workforce 2540 printed that is allegedly Airprint enabled. I can connect and print with a USB cable but can't connect via Airprint. My colleague running 10.7 can. Is this a feature of 10.8?

iOS devices use AirPrint to connect to a supported printer. OS X will use Bonjour to locate and connect to the same printer.
With the Epson connected to your wireless router, when you open Print & Scan and click the plus button to add, does the Epson appear in a small box with a heading of Nearby Printers?
If not and a window appears showing Default, Fax, IP and Windows in the toolbar, do you see the Epson with the Default view selected?

Can't connect via webdav to server 4

Since upgrading to Server.app 4, I can't connect via WebDav. I keep getting one of two connection errors:
1., "Unable to connect to the server. Check your internet connection and server name."
2., "Authorization error: Please check your login and password for this server."
I am using the same login and pwd as sftp, which works just fine. Also, I am on the same network as the server.
Any help would be greatly appreciated.

I've had similar issues. I haven't completely resolved them, so I went back to Mavericks/Server 3 and I'll wait for an update. For what it's worth:
1. I was able to sign in as a different user. Both users (successful and failed) have the same permissions on the WebDave share, according to Server 4.
2. I never was able to sign in from a Windows 7 machine. The discussion linked below explains why:

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.

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:

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.
