OS X :: Cannot Connect To Internet Via Ethernet Or Wireless
Oct 1, 2009
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.

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?

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 an iMac 10,1 and am unable to connect it to the internet using an ethernet cable.
I have a more recent Mac Book and I just plugged in the ethernet cable to it, clicked the setting in Network settings, and I was connected.
On the iMac it keeps saying, diagnostics can't fix it etc..?
On the left panel in Diagnostics, Ethernet has a green light, Network Settings an orange light, and ISP a green light (internet and Server are Red).
I'm using Comcast cable, and they just say the settings should appear automatically on a Mac (which they apparently did on my Mac Book!) ...

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'm here at university and the wifi here sucks! it is so slow, it is working.However there is an ethernet port and I did connect to it this morning. But, this evening I tried connecting again and it wouldnt let me!At my university they require you to put in your student ID and pw in order for you to use the internet for both wi-fi and ethernet. But when i tried this evening it dint ask for my student ID or password. I went to settings and it did say that there was a connection and that "Ethernet has a self-assigned IP address and will not be able to connect to the Internet"
i dont understand how come now it isnt working. I aksed my classmate nextdoor if his internet port was working through the ethernet port he said it was.... i am not that tech savy so keep vocabulary to something simple lmaooo.

I can't seem to connect to the internet using my ethernet cable. I messed around with some of the ethernet settings but now forgot what was the default one. The strange thing is, when I go into windows mode, the ethernet cable works. its just in Mac OS mode it doesn't.

I just installed the Home Edition of Windows XP (from 2002) via Boot Camp. I'm having trouble getting online in Windows. Most of the Internet options seem to revolve around modems, which I don't have. I use a router connected to my computer via Ethernet. There's also a wireless function, which I can use in a pinch.How would I get the Windows side to connect to the Internet via Ethernet? I don't intend to spend much time online on the Windows side (due to viruses), but I'd like to be able to go online if necessary.

I don't know what happened, but a connection that I use frequently has suddenly stopped working on my 4-year-old MacBook (10.5.8). I have tried some of the fixes suggested for wireless connection problems, but none have worked. I live in a place where wireless is not always a viable option, so I need my Ethernet connection...

I have a blackbook (intel core 2 duo) and I can connect to my landlord's wireless network (they have a netgear wgt624) but I can't actually use the web (Safari or Firefox will just "think"). I've tested the diagnostics and it confirms that my mac can connect to the network, but it cannot connect to the internet. The network uses WPA personal and it has a 19-aphanumeric passphrase.
*Also - would it be possible for me to extend the wireless range (and make it possible to browse the web) if I used my own 2wire wireless modem to connect to the netgear wgt624?

Today when I turned on my computer, it suddenly would not recognize any kind of Internet connection. The Ethernet cable that I use every day now shows up as 'unplugged' even though it is plugged in. I have tried using a different cable, and it still shows up as unplugged. When I try to connect to the Internet wirelessly, there is always a connection timeout and I can't connect. I use a self-assigned IP address and I've never had this problem before. I've also reset my PRAM, but it hasn't worked.

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.

My father in law had a power failure at the house, and since then, he cannot connect to the internet via DSL Modem connected via ethernet cable. Being that he is 1000 miles away, I am trying to diagnose via phone. System Info: Imac 17", purchased new around 2006- Intel chip, running Tiger OS
Symptoms:
- Cannot connect via ethernet
- When searching system profiler, "Built-in Ethernet" shows up, but no MAC address
- In Network settings, he can see the various connection ports, but cannot check the box on "Built-in Ethernet" to turn the port on... won't let him.
- Wireless is not an option, I don't want to be 24/7 tech support
Diagnosis? I am thinking that the power surge may have fried the ethernet port on the motherboard.
Repair Solution: Planning on picking up the Apple USB Ethernet adapter. I know it doesn't have the correct drivers to run on Tiger, but found a driver online that claims it allows use of the usb adapter on Panther on up.
Questions - Does this sound like a fried ethernet port? Any other easy diagnostic tests I can do? Does the USB adapter sounds like a decent solution?

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 can't connect to the internet via my ethernet cable, but this is a weird case. What's weird about it is that all my settings are O.K. (appletalk on and set to ethernet, tcp/ip set to ethernet, dhcp) and my iMac is recieving a 192 address, but it still can't connect to the internet. The dhcp settings are correct, because they are the same settings used on all my other devices (at least those that use internet anyway), and they all connect to the internet just fine. Whether via an ethernet cable, or Wi-Fi.

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 recently got wireless internet. Before, the Mini worked fine connected by cable. It has never been connected to a wireless before. The wireless router works correctly, my $250 PC connected to it instantly. There is a yellow light on Airport and it automatically populates an IP address, whatever that means. I haven't installed any new software since it worked with a cable, no funky setup or third party anything- it's just a mac mini plugged into a TV I watch Netflix on and that's all.
My ISP said it's a problem with the computer, the Mac free support could not fix it. I really don't want to pay for an extended warranty or phone support on something basic that this computer should just automatically do. I haven't tried typing in a manual IP address- I don't know what that address would be. If all else fails, I will just run a cable to it again.

I have a MacBook Pro that I have had from about 3 years now. It's been great but earlier this week, it wasn't able to connect to the internet here at my school (college). I didn't think too much of it because my schools internet is always spotty and goes down from time to time. Yet when I go on to my computer tonight nothing I do with my airport or computer will get my webpages to say anything other than "Server not found". I tried turning off my airport then back on and reselecting my network because usually that helps. It would say it connected and I would have full bars but still the same error message. I tried again, and when I did it this time, I did it from within the system/network preferences. When I did this, I watched the connection of my airport go red, then I would connect and it would go to yellow saying I had no IP address.
I would then sit and wait and eventually it would fully connect giving me the green go-a-head. But, again when I would open up my internet, I would get the "Sever not found" message. I would then quit my firefox all together and tried again that way and still same massage. I restarted my computer and tried again...nothing. I became more concerned because my roommate could get on the internet just fine and I could use the wireless in my room through my phone. I was consered that now this was a matter with my computer and not just the internet, so to make sure I got out my ethernet cable and hooked it up with my connection in my room.

I was happy to get my mac pro yesterday, but upon setting it up, I couldn't get it to connect to my network. When I clicked I the airport logo and the top right, it said airport was on and I was connected to the network. However, when I opened up Safari I got nothing...just a screen that said something like "you are not connected to the internet." The last time I had a macbook, I turned it on and bam, I was connected to the internet right out of the box.
After trying to fix it for 30 minutes, I decided to reset my modem/router. After doing this, the macbook connected to the internet for a few hours and I went to bed. Now I come home today and it works for about 30 minutes and then stops working. Keep in mind, my PC is working flawlessly so I know my network is up and running. After about 30 minutes, it connects again...and then stops working again. Very frustrating. As I type this message, it still wont connect to the internet even though the computer says I'm connected to the network.
Another thing that makes me think there is a hardware problem is that the macbook wont connect to my wireless printer. I've installed the software 2x and right after going through the install procedure, it will print for about one minute and then it does nothing - I get a message that says something like "your printer is not on or not connected to the network." So then I went through the steps of connecting it again and again. Every time it would ask for the password to the network so I put it in and it says I'm connected....but nothing will print. After the 3rd time, I was finally able to make it to spit something out wirelessly from my macbook...but 5 minutes later it's back to saying my printer is not on or connected to the network. This is weird because initially it works and then it stops. During this whole procedure, my PC recognizes it just fine and prints within 5 seconds. For some reason the mac just wont do it.
I thought macs were supposed to just work, but this laptop has been more frustrating than any PC I've owned. Here I am with a new macbook that can't connect to the internet OR my printer. Granted, I know very little about computers so maybe I'm overlooking something simple.
If it's a hardware problem, do you think Apple will refund my money?

I have been a mac user since 2006. Yesterday, I purchased an iBook G4 for my father, who I have converted from Windows to Macintosh. We are 99% satisfied. Everything works great except the wireless internet. Whenever the computer shuts off or goes to sleep, we have a difficult time re-connecting to the wireless internet. After five minutes of clicking on the wireless signal (at the top of the screen) and turning it on and off, we are able to get on. Once we connect, it does not seem to disconnect.

Have 2011 13" MacBook Air. I erased my hard drive using cmd-r at startup to enter disk utility. When I restarted, Internet Recovery automatically started to try and connect to my wireless. It never asked for a password. It never connected. Error "-2002F". Tried it again, this time selecting a new network, entering my network name and password. Still will not connect. Have repeated many times. Looked at my access logs on router, it is not connecting.

So here is the issue.. when i first got my macbook, it connected to the wireless internet at my house perfectly and stayed connected. (I had an open wifi account) Then, we got a new router and we wanted to put a password on it so that no one could use our wireless connection without us knowing.
Now my macbook will not connect to the wifi.. It just keeps telling me that the password is invalid. I have a TRENDnet router (TWE-632BRP) but my iphone connects to the wifi fine using the password.

I'm sure this has been posted, but my search pulled up hundreds of threads. After I scanned the first 50, I decided to just post my question.
I have to wait a few days (at most) for my job to register my MAC address so that the new Mac Pro has access to the network/internet via ethernet. It does not have an Airport card or Bluetooth. While I am waiting, is there a way to connect the Mac Pro to my Powerbook (which has Wifi internet access) such that it can piggyback on the internet connection as a temporary solution?
