Intel Mac :: When Sharing Internet Through Ethernet Wireless Internet Dies
May 22, 2012
For specific reasons, I needed to connect my Synology DS211 NAS to my iMac directly via its ethernet port. I discovered that if I share my wireless internet connection (coming from my cable modem/wireless router) from wireless to ethernet, then the NAS would get the IP stuff it needed to show up. did that, voila, NAS is acting like a glorified external hard drive. BUT, when I did that, I lost all internet connectivity on my iMac. Still have full wireless signal. preferences pane says I'm fully connected to my network with an IP address, but safari always fails to pull up any webpages, saying I'm not connected to the internet.As soon as turn off the ethernet PORT, it all starts working again. And to make it even crazier, I discovered that if I leave sharing my wireless internet via my ethernet port ON, but turn off the ethernet port (in pref pane), I can STILL access the NAS just like before. That makes no sense - I'm sharing my internet via a port I have turned off, but it works? Anyway, why would Iose my airport wireless internet connection when the ethernet port is on - configured manually?

So far I haven't been able to get an airport connected computer to share its connection via ethernet with another. Am I doing something wrong or is this not possible?

Recently got a Mac pro. However my room only has one network socket going into my router, this goes to ethernet port 1. Internet works fine, no issues. However my old desktop (that the MP replaced) can't get online now - no second network port from the router into the room the computers are in. I have a crossover cable that I've used to connect the 2nd MP ethernet port to the PC ethernet port. However I can't get internet access on the PC. If the PC and port 2 are on their own subnet (not the router/port 1 subnet) I can get file sharing going between the MP & PC, but cannot figure out how to get the router/MP/PC on the same subnet together using both ethernet ports of the MP. I have already tried enabling internet sharing under system prefs etwork, but it doesnt work. Network: Router (connected to internet) at 192.168.1.1 - connected to mac MP port 1 - 192.168.1.2 - works fine in connecting to the net MP port 2 - 192.168.255.1 - works in networking to PC for filesharing PC - 192.168.255.2 - works in networking to Mac for filesharing Any combination of 192.168.1.xxx for the MP port 2 and PC, they can't fileshare anymore and there is still no internet for the PC. Anyone know how to do this?

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.Â
Are you sure you want to turn on Internet sharing? Â
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.Â

I'm renting a house for the week with several friends, and there's only one ethernet port. I figured I could plug one friend's Powerbook G4 into the ethernet, go into Sharing, turn on Internet Sharing, and then nearby computers could borrow the connection - this isn't working. The network doesn't even display on my other friend's powerbook. The little upwards arrow does not display ontop of the airport icon in the menubar, which I think it's supposed to, what's going wrong? I have "Personal Web Sharing" turned on under "Services," still no go...

I was wondering if anyone knows if its possible to share my LAN internet to an XBOX 360 using the Apple USB ethernet cable (for the Macbook Air) on my Macbook Pro 13"? I've tried several routers, and all have them have failed me giving me massive timeouts and sudden disconnects. I think this should be a good solution.

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.Â
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?

MacBook Pro with Retina display, OS X Mavericks (10.9.3)

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?

I'm brand new to Mac. I just got a MacBook Pro, and I've been having some troubles connecting to the internet at home. I have a LinkSys WRT54GS router with Firmware Version: v1.50.9. I'm unable to access the internet through both ethernet and wireless. Concerning wireless, I have tried connecting using WEP, and have tried entering passcodes both with and without an "$" and "0x" preceding the 10 digit WEP passcode. I have also tried switching the encryption over to WPA2, and still nothing. I have even disabled the security to see if it's able to connect -- it's not. I had some error regarding not being able to find it's IP or something along those lines.

My BT Router is about, say 150M away, could I get a 100M Ethernet cable, plugged into the Router, going along the walls and then into another Router.
Then, from that Router have another 50M Ethernet cable going directly into my MacBook Pro?
So, like: ROUTER --100M-- 2nd ROUTER --50M-- MacBook Pro
Is this possible, or is 100M the end point? Can't go any further than that?

My macbook wont load any web pages. It is connected to my wifi network and it says my Internet connection is good under my network settings. All my other devices on the network have no issues (ipad2, 2-iPhone 4's and 2-PS3s). Also when I connect my MacBook to my router with an Ethernet cable it loads any and all web pages instantly. I also tried installing Firefox thinking it may have been an issue with safari. No luck there. The issue was intermittent at first and would require I restart my computer/router and then issue would be corrected. Now the internet wont load any pages at all. I also tried zapping the PRAM, flushing the DNS cache, removing files from the system config folder under Library/Preferences/system configuration and a few other things I can't exactly remember. My MacBook is up to date, my routers firmware is up to date. I even tried tethering my MacBook to my iPhone via wireless Internet and still could not load any websites.

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 recently completely a wire pull from the network hub (Dell Power Connect?) in the office of a church, to a computer in a different room of the church. I plugged in the cat5e cable to the computer, it connects to the network, computers on the network can access it's public folders and remote access it, but the computer cannot browse the internet using the built-in ethernet plug. The wireless-internet on the computer allows me to navigate the internet just fine.
With the Airport turned off, and the ethernet plugged in, I can ping [URL] with 0% packet loss, but when I try to connect to google on Safari or Firefox it says that Safari/Firefox cannot connect to the server.

I'm running OSX 10.5.8 on a Macbook Pro, and today I've been unable to connect to the internet via ethernet or wi-fi, unless I'm in safe mode. Then everything seems to work as it should, which makes me believe that this is a software issue rather than a hardware problem. I've tried making a new account with administrator priveleges, but that doesn't solve my issue. Does anyone have any advice on how I can connect to the internet under my normal user account, rather than in safe mode? I should note that I won't be able to get my hands on my repair CD or perform a clean install of OSX because that stuff is at home, and I'm in college. Also, I'm at a university and don't have a router. I just use the campus-wide wi-fi. Finally, my roommate has no problem accessing the internet in our room via ethernet or wi-fi, but I do. Thanks for the help everyone.

I have been using my airport card in my iMac to share internet wirelessly with my iBook. However, I am unable to share the internet wirelessly with a friend's windows laptop. Her computer sees the network but does not ask for a password and fails to connect.

After applying the recent software update version 10.7.4 to OSX Lion, the internet sharing gets disconnected periodically. But when I look at the internet sharing icon on iMac, it states that it is still on and according to iPhone, it is still connected to the wifi, however, there is no internet connection. I have to turn off the internet sharing and wifi from the iMac and turn it back on and switch channels in the internet sharing and it works again. But this is getting to be frustrating as I have never encountered this issue since the update. I think the recent updates is bugged.

this is a major problem for me. I just installed ubuntu on my mac via boot camp, and I can't find how to set up wireless internet! Once, after installing windows, the same problem occurred. I'm not sure whether this version doesn't support airport (ubuntu v10.04.1) or I need the snow leopard drivers (but I can't because it's a .exe file).

My iMac's Internet Sharing since one week still be very slow. I have a realy fast Internet on my computer, so, that's not a problem. I use IS for my iPad and it opens only 1-3 pages, then it just stills loading. One week earlier I could watch films etc, so it worked. The same problems are also with catching it on my iPhone, so the problems is by iMac. It writes "connection timeout" or something like this.

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:e5Â
DHCP Server 192.168.0.1Â
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.

My wireless network is connected to my iMac but the internet goes down a lot and I have to reset the wifi up in the menu bar. It doesn't lose bars at all or say its disconnected. My wireless printer always works just fine. None of the other computers in my house have this problem.

I currently have my mac connecting to a wireless network and have since plugged in a ethernet cable to use because I can get a better connection, but even with it plugged in I still seem to be connected to the wireless network How can I make it so its only using the ethernet connection?
