Hardware :: No WAN Ethernet Detected - TC Cannot See Cable Modem
Dec 29, 2009
I've got an issue with my TC setup, I cannot for the life of me get it to see the cable modem and setup the WAN access. If you will pardon me I will cut n paste the lengthy description I left on the apple support list as I feel it is pretty thorough. I think I know my way around networks and dhcp but this setup doesn't yield any logs so I can't troubleshoot! I'm on Virgin Media 20megs and I can't connect using my brand new TC.
Modem: Ambit 256
Time capsule : 1 tB, firmware 7.5
Test router : Netgear WGR614V9
MBP alubook 15 inch late 2008
I tried connecting with the test router and the MBP alubook to the modem and both can pickup the ethernet connection and get a DHCP lease after some coaxing (cold-start the modem first, then cold-start the router/mbp). But I'm having no luck with the airport extreme base station. Hard reset / factory reset / soft reset, any startup order, nothing works. I even left the devices offline for an hour before doing another round of testing. I tried several cables (including a crossover cable) and all configurations work apart from the ones involving the time capsule. Both the modem AND the TC ethernet ports light-up with a green light... but somehow the TC doesn't negociate its DHCP or even basic ethernet connectivity. I see there's a firmware 7.4.2 on the support site for the TC but I'd rather not downgrade the unit.
Here are the console logs from the MBP when it connects to the modem (yes, my MBP is named awesome, because frankly it is):

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 was wondering how I could file share, or make the whole Hard Drive (HDD) accessible to another computer. The two other computers I have are a Toshiba Laptop with Ethernet and USB, and a iMac Intel with Firewire, USB, and Ethernet. Putting these to use along with:Three Ethernet Cables Now how do I get the whole HDD visible to the others computers (either/both) and be able to write to it? Also, I do not want to use CDs and have no CDs that came with the computers. I want to put Xubuntu on the eMac and Debian on the iMacs and erase the rest of the Hard Drives. The computers getting this are the iMac G3s and the eMac G4 in my Signature.
I was just wondering if any other macrumorsmembers have been in the situation where there's no wifi, no decent 3G, but ethernet ports available to use, but you don't have a computer handy? Would it be possible that you could create an ethernet cable one end, dock the other, and literally connect e.g. an iPhone into the ethernet? At my place of work, there's no signal (dodgy GPRS/flakey Edge), some wifi, but in halls of residence, you get 1 ethernet port, and you can't put a wireless router onto it. It would seem that it would be an interesting solution, if it was possible.
I've been using cable broadband for years and had no trouble at all connecting the supplied ethernet modem to my airport extreme base station. Unfortunately recently I have moved into an area not covered by Cable and am now having to use good old ADSL2+ phone line broadband.
This has caused me more headaches than i care to mention, drop outs, bad port forwarding/triggering, failed upnp... You name it, it can't do it!
The supplied modem/router is basically a pile of poo and the ISP won't supply me with an ethernet modem. Also, the router won't going into anything even remotely resembling a "modem only mode". It seems to want to do all the networking itself and gets into a huff if it can't.
So, my solution is to buy an ethernet modem and hook that up to my ever faithful airport extreme base station. But I have no idea which ones are reliable or efficient or work best in this setup environment.
Can anyone please recommend an ethernet modem that they either use or have seen in action, I really want the headaches to stop!
I just brought a brand new IMac today but could not connect the internet with the cable though the cable does work with other computers. Do I have to change the settings or .....? Or its the problem of the jack?
I recently purchased a SBG900 Motorola cable modem/router to use with my IMAC. For a beginner, I found the setup instructions woefully lacking. I have managed to set up an "unsecure" wireless connection with the 900. It works fine for websurfing. I cannot however send email. When I do, I get a pop up box saying that my email connection to the Apple server on port 25 has timed out. I am able to receive email just fine. I wanted to sort this problem out before attempting to "secure" the network. I'm guessing its somewhere in the Motorola setup but I'm not sure where to start.
I have a Power Mac G4 MDD that I am trying to connect to the Internet using a USB Cable Modem from Broadstripe Cable in Maryland.
So far I have tried a straight connection using the supplied USB cable, then via an Ethernet adapter from the USB cable to the MDD. Went through the software setup several times and still have had no success. does anyone have a solution for this type of problem?
I've scanned Google for my problem but when I tried setting an IP address, I got no connection, I don't know if it because I dont have a LAN or what... I need to set a static IP address so I can port map on my airport to open port 6112 for hosting wc3 games. I have a motorola surfboard cable modem and an airport extreme base station. I connect using DHCP via ethernet. Any feedback would be wonderful!
Upon getting my iPad and being unable to stream much without huge wait times, I've decided to take the plunge and get an Airport Extreme. Well, it arrived today, but alas it seems that I need a modem and Ethernet cord! Now, in my defense, I've been using a router that is both a modem and a router for years -- and it connected straight to the cable jack, so I didn't know that most routers needed a separate modem unit and Ethernet cord! Any way, it's too late to head out now so I'm going to have to wait till tomorrow to stream my precious netflix -- but I want to get it right this time; so...
I need an ethernet cord to connect the router and modem, right? The Modem/Router I've been using is called the SBG900 Wireless Surfboard Gateway. In my experience, the speeds have been dismal, but I should be able to use this as my modem -- right? Will it be slower than if I bought a separate modem? Does the modem even effect the speed of your internet or is that just the router?
I currently have a wireless network set-up through Comcast. I have a Netgear modem/router from Comcast. I just purchased Time Capsule and I would prefer to use TC as my wireless network router instead of the Netgear modem/router. Do I need to have Comcast supply a new modem without the router or is there a way to connect TC and the Netgear modem without using the built-in router?
I'm using an airport extreme (latest firmware) with 10.6.3 on a mac pro and a macbook pro. The mac pro is wired the macbook pro is connected via wireless.
I constantly have signal drops. While the airport extreme seems to stay online (green light is sold) the cable modem always resets itself.
I can't figure out if this is because of my Optonline service or due to my router (airport extreme). Cablevision states nothing is wrong with my cable internet connection and the issue may be with the router. I've tried three different modems from them and they've supposedly checked everything (wires, signal, etc). I still think it has something to do with them. I'm hesitant to try DSL as it is slower (no fios here yet).
I don't get how it can be the router if both my desktop and laptop lose connection to the internet at the same time if they happen to be connected online at the same time.
Is there anything I'm overlooking in regards to the airport extreme? Should I trash a particular preference or try a different setting?
I'm kind of desperate at this point since it is highly annoying to constantly get knocked offline more than 5 times a day.
I currently have a DSL internet connection (static IP if that matters), and my iMac is connected to the network via an Airport Extreme, but am switching to Comcast Cable for better speed/price.
I picked up the self-install kit from Comcast yesterday and find the included instructions pretty much worthless.
Due to where cable outlets are located, I hope to install the new cable modem in a different room than my computer. However, will I first need to have the computer hard-wired to the Airport to configure the connection? Or should I be able to configure it wirelessly?
If wirelessly, should it be as easy as turning off the computer and Airport, connecting coax from the wall to cable modem, ethernet cable to the Airport, and then powering everything on? Will the iMac instantly recognize the new connection and walk me through configuration?
I am going from a static IP w/ the DSL to, I assume, a dynamic IP with the Cable. Does this further complicate the install?
2010 i7 15'' MBP. I've been connected to the internet wireless with my Airport Extreme from day 1, but today I wanted to give the ethernet port a try and it just didn't work. The ethernet cable is recognized, but it says there is no IP. I do not know my IP settings or any of that. What do I do?
I have a crossover cable and I need to connect my imac to my macbook so I can download some of my files on my macbook to my new imac. I know I have to go to Preferences > Networks > and change the ethernet settings but I'm not sure what to do.
I have tried searching for a similar question but have not been able to find an exact match. I have a new MacBook, a PS3, a Virgin Mobile USB and an Ethernet cable and I thought putting them all together so I could use the PS3 online would be easy! Could someone please give me a step by step process of what I am meant to be doing.
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 have a MacBook Pro with OS X 10.5.6 I connect to the internet with an ethernet cable direct into the wall. When I open the network connection box, it says the ethernet is connected, but it will not load any web pages. Friday I was using it fine and then got off. Came back a bit later and could no longer connect to any pages. I have spoken to my internet provider and they say my settings are fine. I am online on my desktop that connects using the same ethernet cable. I am not having any trouble connecting on it. I went and bought a new ethernet cable, just in case it was the problem
plan to transfer from my Windows PC with the migration tool.I would like to know if it's possible to connect directly my PC to the Mac with an Ethernet cable. Is this considered as the same domestic network?
Info: iMac (21.5-inch Mid 2011), Mac OS X (10.7.3)
