Mac OS X Lion Server :: No Connection To The Internet With Ethernet, Only Over Wifi?
May 28, 2012
After switching to a new provider and getting a new dsl modem (a fritz!box fon 7390) I tried to setup my homenetwork again. Now the weird thing is: my Mac Mini running OSX Lion Server doesn't seem to be able to connect to the internet over its ethernet port, only when using a WiFi connection...When it's connected with ethernet it can reach the dsl modem without any problems, but it can't ping/telnet or anything else through, only over WiFi... As long as I use the mini servers WiFi connection everything works fine, but that doesn't make any sense to me.I've checked the servers setting and the Fritz!box settings and I can't seem to find anything obvious. Of course I could just go on and use the WiFi connection...
ps: all the other computers can connect fine using either wifi or regular lan connection... I even tried the exact same cable with another laptop just to make sure...

I am on a Mac Mini connected to the Net via a FON wireless router and Ethernet directly to my broadband modem. I have had problems with both the modem and an Airport Extreme, which eventually died, but I am back up again with the modem via the FON router.The odd thing is that I can't get Ethernet to work over a direct connection to the modem. Diagnostics tells me that the ISP and Internet fails. I can connect to the modem over Ethernet, however, change its settings etc. in my browser. There are solutions mentioned here involving changing the etc/authorization file, but wouldn't that also affect the WiFi if that was the problem?
In short, Ethernet connection to modem works. WiFi connection to FON router and then to the ISP and Internet works. But the Ethernet configuration does't go that last bit, it only works locally. Using that route, I can't connect to the outside world. I have restarted the modem, the computer etc., but that should not be the problem as both works over WiFi, using the same settings for the modem. How do I best troubleshoot this? I am getting an AirPort Express, perhaps it will work better with the modem that the computer itself, but I doubt it.

I know this has been a wifi issue for many, but this is occurring with ethernet as well on our iMac 2.93. Only began with Lion update. All other 5 Macs (Snow Lep/Lep/Tiger) and several PC's on network have no problem. Have set iMac's internet connections to static/manual ip. Worked for a few days, then back to dropping. This is obviously an OS issue.

Now, the internet connection to my macbook pro stops working. The MBP is 4GB memory with intel core i7, with OS X Lion 10.7.4.
It shows that the ethernet is active. But it can not connect to the internet.
I tried to unplug/plug the ethernet cable; and renewed DHCP lease;use the same ethernet cable for another computer and it works for the other pc.
But for my MBP, it still does not work.

I am having internet connection issues with my MacBook Pro 2011 - running the latest version of Lion OSX. My connection cuts out regularly (every 10 - 15 minutes) despite having a full wifi signal. It is happening on two different routers, in two different locations with two different ISP's.
When I run Network Diagnostics ISP is the test that fails, but after a couple of seconds diagnostics fixes it until the next 10 - 15 minutes. The only other alternative is turning wifi off and on. Both of these only last for the 10 - 15 minutes before it cuts out again.
It is very frustrating and research online seems to indicate it is a Lion issue. I have made an appointment with a genius, but browsing online it appears there is no solution. It is not acceptable.

Configuration: I have the latest iMac running Mountian Lion. I connect via WiFi to a Linksys modem that is connected to my ISP's WiFI modem which connects to a tower a few miles away which, in turn, connects to the ISP's processors somewhere nearby.
On the network diagnostics Network status there are indicators for WiFi, WiFi settings, Network Settings, ISP, Internet and server.
Occasionally the internet and server indicators go to yellow and then red resulting in no connection. I have reset the Linksys, the ISP WiFi modem, both and it does not seem to make any difference. Eventually the Internet and Server indicators return to green and the connection is restored. When they are yellow or red, it affects all processors in the house (iMac, Macbook Pro, iPad, iPod, etc).

I have a really crappy connection at home, about 50 ~ 60 kpbs. LOL. Cheapest AT&T DSL, $19.95. I have a wireless router hooked up right now. Is it possible to utilize my WIFI and ETHERNET all at the same time to double my connection speed? If so how? I'm running 10.5.

I am sure this may have been asked before , but I am having a problem finding an answer. I have an iMac (2008) and my wife has a ACER E500 PC (No WiFi connection), running Windows XP Media Edition. The only internet connection we have is to my iMac, so as both my iMac and my wifes PC both have Ethernet connections , I am trying to share my iMac internet connection to my wifes PC via an Ethernet cable, I am having no luck in getting it working.

Ive got a pretty fast internet connection at home and I have just realised that when I plug my iBook and desktop pcs into my wireless router ethernet (LAN) ports I get a much faster internet connection speed compared to the wifi.I.e. 12-17mbps when through ethernet and when I connect to the wifi I get 2-4mbps. My computers are all located in the same room no more than 5 metres away from the router.

I've been trying to connect over internet sharing from my Macbook pro to my i-pad 2 and am having some issues I hope someone can adress. I go to Settings>Sharing from ethernet then to wifi. I name the network choose a channel then add a password from there I get this error message.
Are you sure you want to turn on Internet sharing?
If your computer is connected to a network, turning on Internet sharing may affect the network settings of other computers and disrupt the network. Contact your system administrator before turning on Internet sharing.

How to connect my powermac g4 to the internet. I was told that it has the "built-in ethernet" and that all I need to do is config it so it will pick up the wireless signal from the router on the main family computer. But whenever I go to config the network connection, and check the status, it tells me that the built-in Ethernet is not plugged in. Do I not have the built in ethernet? I just want to connect to the internet, but I don't want to spend over $120 to have geeksquad come and do it if I can just do it myself.

I currently have MacBook 13" and iMac both running on Snow Leopard. I have no problem connecting to the internet via Airport Express wifi but if I have to connect directly to internet from Ethernet port using Ethernet connection I can't connect to it. The Internet and Server lights are showing "amber" in the network diagnostic tool.
The modem is the DLink DSL 302G. I have used http://10.1.1.1/ to ensure the username and password of the ISP are correct. What I don't get is if it works via Apple's Airport Express router why wouldn't it work with straight Ethernet connection from the modem?

I have a Late 2013 MBP Retnia. I have WiFi access via a captured portal. I have other WiFi and Wired (Ethernet) devices that can not authenticate to a captured portal.
Question:
1) On the single MBP mentioned can I connect to the captured portal WiFi via one band (say 2.4) and then become a WiFI hotspot with the other band (say 5)?
2) On the single MBP mentioned can I connect to the captured portal WiFi via one band (say 2.4) and then share the Internet connection to the Thunderbolt Ethernet connector?
Info:
MacBook Pro with Retina display, OS X Mavericks (10.9.3)

I connect to the internet mainly through an ethernet cable, connected to my own base for ethernet connections (Might be a router, but doesn't connect directly to the internet) which is connected to the main Linksys router on the other side of my house, which even has a wireless connection.
Regardless, this setup has worked without issue for a long time now, but all of a sudden now, I cannot connect to the internet (On my Mac).
I have tried unplugging the routers, for extended periods of time, plugging them back in, but I cannot connect to the internet. Whats awkward, is that when I check the Network settings in the System Preferences, it says clearly is that the Ethernet Cable is connected (Which it is), and as a backup, I have even connected to my Wireless Network through AirPort (Which says it is connected), but I cannot connect to the internet through Firefox, or any instant messaging service.
On the main computer, with the main router, the internet works fine. When I try to load Firefox on my Mac, it sometimes takes a long time loading (On a blank screen), and never loads usually (With occasional loads, but usually does not connect).

The last few days I've had a problem where the Internet network connection speed on my Power Mac slows to a crawl (about 1Mbps) and can only be fixed by re-starting the Mac which restores normal connexction performance for a while. The Internet connection runs at around 35-37Mbps and is routed via a BT HomeHub 3. The laptops which connect via WiFi don't show any slowdown in speed tests, only the Mac Pro, which is connected to the Hub via Ethernet. I've tried swapping between the two Ethernet ports on the Mac but it doesn't make any difference. The HomeHub has been in for about 5 months but this problem has only just started in the last week or so and the period for which the restart restores the network performance seems to be decreasing. Is there any way to reset network software, or some prefs I could delete? It's an early 2008 eight-core Xeon MacPro running 10.6.8, 8GB RAM.

I've got an ethernet cable and i thought i'd share my internet connection through 'sharing' under network preferences, to allow the windows 7 computer to get online as well.
the windows laptop cannot connect to the internet. I've managed to do this before with no problems when i was sharing a USB 3G dongle's connection over wifi.

I just got a new MacBook and have been copying files via Ethernet from my pc. One thing I noticed is that whenever an Ethernet cable is plugged in nad hooked up to the router, the Internet stops working on both mac and pc. However, my torrent client on my pc continues downloading so it's not actually stopping, the browser is just failing to connect as is the official network status. Why is this?

I just got a new MacBook Pro, but my wife uses my old 1.25GHz Alum. PowerBook. My MB pro flies, but unfortunately, the wireless ethernet on my old PB is slow as hell. I've got 11+GB of free space left on my hard drive and Safari or Firefox are the only applications I have open. I also have a cable internet connection with wireless through my 1st Gen Airport Express, yet it's still slow.

I was wondering if it is possible to connect a desktop and laptop computer using apple share or bluetooth to share an internet connection that is connected through an ethernet port on the desktop. My internet company is crap so I need to find a way to cut out the router, which I have to reset all the time to get a normal internet speed.
Desktop is a Mac Pro bought last April, and the laptop is a 12" Powerbook G4. Both have bluetooth, airport, and the newest operating system.

i share a house with my brother, lucky me He got a PC with Vista in his room. I got a lovely imac in my room. He gets the broadband cable direct into his room. It averages 40 mbps download , 1.67 upload. We use a wireless Netgear router one thats suppose to handle N wireless and i pick the wireless up on the airport extreme in my imac. Unfortunately i only get about 12 mbps download , 1.20 upload, even though i'm only in the next room. We both play WOW online. It works so much better on his PC cos of the internet speed. Could I use a gigabit ethernet connection between the PC and imac, to share the internet and still play WOW independently?

At the moment, I have an ADSL modem/router (1 port) connected to my switch (ethernet port 1 on the server and all my clients are also connected into this same switch). ADSL router has IP address 192.168.2.222 (assigned manually - outside my DHCP range). X Serve operates as DHCP for everything else and I put the default gateway as 192.168.2.222. Internet works fine on all computers (including server). But I want the ADSL modem/router to be connected to ethernet port 2 on X-Serve (not straight into the switch). If I just unplug the ADSL router from the switch and plug it into port 2 of the X-Serve, the server can access the internet, but all clients can no longer. Anyone have *any* clue how to fix this?! It doesn't seem that complicated, I feel I have done everything right.

I have recently had to stop using my wireless router and connect directly from my modem to the WAN port on my computer. However, I can only achieve an internet connection when I direct connect into my PowerBook G4. When I try to connect into my iMac, I get nothing.

I had no trouble getting on line until last week when a message came on that
IP address 192.168.0.139
was in use by
04:0c:ce:54:c1:e5
DHCP Server 192.168.0.1
Since that time, no matter if I plug it into one router or the other (I use a router in my office to share the one ethernet cable that comes down the hall) it claims that the ethernet is working and it knows that it is connected to the Internet,but it cannot access the Internet. IT seems to be stuck in a cycle of navel-gazing, constantly focused on its own ethernet IP address.
All I know how to do is operate the thing; we have no IT person here. A visitor set up our network for us a few years ago. Only the iMac has this problem; my PC laptops go online just fine. But all my work is on the iMac.
