Connecting Help using Cable Modem

I am trying to connect to the internet using a cable modem. It works fine on my PC but when I try to plug it in to my Macbook, I can't connect. First off I figured I could just plug it in and hit connect, or it would connect automatically. Because the whole reason I got a mac was because of the "easy-ness" surrounding them. So can anyone guide me to somehow connect.

The problem likely is not your Mac but your cable modem.
Most cable modems, for some unknown reason, lock themselves to the first device they see. This means that if your PC is the first device to use it, then only the PC can use it - it won't talk to the Mac at all.
The first solution is simple - power cycle the modem. This resets the lock so the Mac can use it (as long a the Mac is the first device), but then you have the same situation with the PC.
The better solution is to get a NAT router that can take the connection from the cable modem and share it between both Mac and PC simultaneously. As far as the cable modem is concerned, it only sees the router and the lock does not matter. Numerous vendors make numerous products that will fill this requirement.

Help Please: How to connect to a cable modem?

Here's the deal: I'm getting a new iBook tomorrow I'd like to get an advance sense of what I'll have to do to get it connected to the cable modem that I'm using with my current Digital Audio G4.
Will the iBook self-configure if I have have it connected to the cable modem when it first starts up, or do I need to record the TCP/IP stuff from the G4 for use with the iBook?
Thanks for your help.

Hi Paul,
If you have a firewire cable, that will work. Just start your G4 up in target disk mode. If you don't have one just connect the two with an ethernet patch cable. Unplug it from the modem and plug it into the iBook then turn on file sharing on both machines. On the iBook select Go>Connect to Server and click on Browse. Double click on the G4 and enter your user name and password (if needed).

Getting an older iMac to use cable modem

I have a PowerBook G4 and a MacBook that are both using the AirPort Express wireless network that I have set up in my home. I have a cable modem and that modem has a ethernet cable that goes from the back of the modem and plugs into my AirPort Express. The back of the cable modem also has a USB port on it as well. Now, I also have a iMac G3 (with a translucent green and clear plastic case) that I am wanting to get online with the cable modem. The iMac G3 is running Mac OS X 10.1.4 with 64MB of RAM. I have a USB cable that can connect from the cable modem and then to that iMac G3. I am trying to find a way to connect the iMac to the cable modem WITHOUT having to buy anything and WITHOUT having to mess up my already setup wireless network. If someone can offer up some tips on how to accomplish this, I would appreciate it. If I need to change how my wireless network is set up a bit, that is fine. Just want to find a way to get all 3 computers on my network while still allowing the 2 laptops to remain on a wireless network. Thanks for any help in advance.

Hey again, Roger. So, here's the scoop. I got my Linksys router back. I unplugged my cable modem for starters. Then, I unplugged the ethernet cable from the modem that was coming from my Airport Express. I then plugged in a separate ethernet cable into the back of the modem and the other end into the WAN port on my Linksys router. I then took another ethernet cable and plugged one end into the iMac and the other end into an open LAN port on the router. I then plugged my cable modem back in. (It has no "on" or "off" switch) I then plugged the routers power cord into the back of it and the other end into a power strip. I checked the Network settings on the iMac to make sure they were all correct. I opened Internet Explorer (the only browser on the iMac) and I got an error of "The specified server cannot be found.". I found this a bit odd since I had everything connected correctly and the settings correct. Then, I tried restarting the iMac thinking that may do it. It didn't do anything. Then, just for kicks to see what would happen, I pushed the "reset" button on the back of the Linksys router and held that for a couple seconds. After releasing it, the router restarted and the lights were flashing on it again. Then I went and checked the settings again for the iMac and they were still correct. Then I typed in that IP address http://192.168.1.1/ and it asked for a password. I typed in that password and it brought up the settings for the router. I made sure they were all correct according to what you told me. I then tried going to http://www.apple.com/ to see if it would work yet. And this time it did. It connected just fine. I read in the manual for the router and it tells you to hit that reset button on the back after setting everything up. So, I got the iMac online just fine and dandy now. And everything should be working great, right?? Well, its not. Here's my problem. The iMac goes online just fine. I set the Airport Express to Bridge Mode just like you said. I checked the settings on both the MacBook and the PowerBook G4 to make sure they were right. I tried opening a website on both of the laptops and neither one of them wanted to connect. They could not find the Airport Express. Now, I am NOT saying what you told me is wrong. But what I am saying is this. I must have missed another setting or something somewhere that makes this work the way its supposed to. What else do I need to do in order for the laptops to find the Airport Express? I DID connect the ethernet cable coming from the Airport Express into an open LAN port on the router. So, I know that isn't the issue. Ha ha. There must be just 1 small thing I am missing and I need to know what it is. What are your thoughts?? Thanks.

WRV54G connection to WCG200 Cable Modem ?

Has anyone tried setting up their WCG200 with a WRV54G?
I'm having trouble and I was hoping someone out there has done it successfully.
Here's what I've done/learned:
1. I've only had success connecting the vpn router with a straight-thru cable from the ethernet ports. (like hooking up 2 routers)
2. I've needed to keep the DHCP service on the cable modem in order for it to hit the gateway.
3. The VPN is set to router (not gateway).
What I've tried that DIDN'T work:
a) Used the WAN port on the VPN router to connect to the Cable Modem
b) Used static addresses instead of DHCP and configuring the VPN router to use the default gateway IP of the cable modem address.
c) Used separated networks like 192.168.0.x for cable modem and 192.168.1.x for VPN and change the subnet mask to 254.
d) Firewalls turned off; DMZ set to IP for VPN router
So, my network is like this:
10.0.0.1 - Cable Modem
10.0.0.2 - VPN Router
10.0.0.3~6 - PCs
Subnet: 255.255.255.0
All clients hooked through the VPN router which connects to cable modem uplink port.
DHCP on Cable Modem
VPN pass-through enabled
I'm able to get out from my internal network with this setup, but unable to QuickLink into it yet. It's functioning just like an ethernet multi-router system all on the same network, basically.
I've tried to use the Linksys default setup disk to setup the VPN in various conditions, but no go, and there's precious little help from the manuals for this case. Any ideas would be appreciated.

HI , what you have done here is that by putting the WRV on the DMZ , you have opened all ports for the WRV.However , on the WCG itself all ports may possibly be blocked. Even though the VPN passthrough is enabled.
Try and forward the VPN ports on the WCG as well (1723,500,50,43-47,445)

For the new airport extreme what type of cable do I need to connect to my cable modem. Is Cat5 OK or will that bottle neck things?

For the new airport extreme what type of cable do I need to connect to my cable modem. Is Cat5 OK or will that bottle neck things?

Assuming that your cable modem has Gigabit Ethernet ports (possible, but it probably does not) Cat 5e or Cct 6 would do the job that you need.
If the cable modem is using a 10/100 Mbps port, then Cat5 will be OK.

Can I connect a Vonage / Basic Talk pjone to the USB port on Airport Express that is connected to a cable modem?

Airport Extreme won't connect with my cable modem (Time Warner)

OK, I'm tired of staring at a blinking amber light. I'm reaching out to anyone out there who's had this problem. I've got everything connected right, the software loaded, the connections set on my laptop (Macbok Pro). But still my Airport Extreme won't connect to the Internet. I've tried different cables, rebooting both my modem and my Airport. For the record, I've had a Mac IT guy from my advertising agency come by my house and make sure that everything's installed and hooked up right. But it still keeps saying that my IP address is invalid, even though I can connect (wired) using the modem.
I suspect I'll just have to take it to the Genius Bar or something. But anybody got any ideas? I really want to join the 'n' generation....

atotheb, Welcome to the discussion area!
Did you power off the cable modem when switching the Ethernet connection from laptop to AirPort Extreme base station (AEBS)? This is usually required.

i have a Linksys Wrt54gs connected to a Cable modem.
it worked for about 8 months.
My kid pressed a button by accident and now it won't work.
the router just keeps resetting.
i unplugged everything.
conencted 1 computer, and everything is fine.
Received DHCP address.
Once i plug in a second computer it starts rebooting.
Both computers are set to DHCP.
NO internet connection is connected at this time for troubleshooting purposes.
Nothing is connected to the ethernet port on the Linksys router (port for internet access), only 1 and 2 are connected.
i reset the router and still nothing.
i can connect 1 computer via wireless and 1 computer via direct connection and all is good. Once 2 devices are connected via direct connections it starts resetting.
i can even connect the modem to the router (for internet access), and connect to the linksys router via wireless from my computer and get internet access.
But once i direct connect 2 connections, the router starts resetting.
i have reset and reboot it with every combination i can think of.

Its good that its working now.
If it happens again, try this :
Press the reset button on the router for 30 seconds. The Power light will start flashing. Turn the Router and the Modem OFF. Turn the modem ON first, wait for 10 seconds, turn the router ON, wait for 10 seconds, you should be ONLINE !!!
Do this when the computer os connected to the router with a cable.
than on the computer open Internet Explorer and in the Address Bar type : 192.168.1.1 and hit enter.
It'll ask for the password. The default password is admin.
Once in the setup page. Click on the Wireless tab.
In there Change the Network Mode to mixed. And change the SSID to your name.
Change the Channel to 11. And Enable the SSID Broadcast.
Save the settings here. After that Click on Wireless Security and configure it accordingly and Save the settrings.
Than click on Advanced Wireless Settings. In there Disable the SES function.

No Connection to the cable modem/Internet with APX

Hi!
My Apple Airport Express BaseStation worked properly for some weeks - but from one day to the other, the ethernet connection to the cable modem doesn't work anymore. The cable modem is working properly, there is NO problem. I can connec to the internet vial LAN card of the computer without problems. But my APX has no connection to the cable modem. The flashlight is blinking orange.
I tried everything - hard reset, soft reset,..... but no change, there is no connectin to the cable modem.
Does anybody know what to do? Can the APX be defect?
regards,
flo

I found the solution: somehow an old and inactive dhcp-server and dns-server setting messed around with the settings. Once I deleted these settings everything started working normally again

Hi, I have a MacBook Pro and a PC both connected to a TC who in turn is connected to a cable modem. I have no wifi accessfrom my MacBook pro (self assigned IP - no internet connection msg) while I do on PC through ethernet? can anyone help?

I was working yesterday afternoon when the wifi suddenly went cold. Initially on the MacBookPro and on the ethernet connected PC. I reinitialized modem and TC through the mac and then the ethernet on the PC worked again and has since.
I've reinitialized both the modem and TC many times, as well as checked the cables. Moreover, I've tried to renew the DHCP lease, provide the DNS servers manually, erased all networks in Network preferences and in KeyChain etc. but nothing seems to work.
One strange thing also happened. I had two networks created, one for me and one I created for guests. The latter one just vanished, dissapeared without a trace.
I've tried from the café down the street and the Wifi worked perfectly well though a little slow, but that could be their connection not the Airport. Therefore, my I deduct that there is either something wrong in the TC or something went wrong in the network settings in the Mac. But that doesn't help to move forward and fix the darn thing.
The only thing I haven't done is completely reset the TC, but after reading a couple of help threads on different forums I'm confused as to how to proceed to get it back to worrk? Has anyone had the same or similar issue and found a solution?
Thanks

Eh la Pastenague! Je savais que tu était léthale pour l'homme mais ce sont pluôt les machines à pommes qui devraient te craindre. Merci! Solved.
For future reference.
My TC is a 3rd gen.
I actually had to reset to standard defaults not only once but twice. The first time I simply returned to my old profile but that only led to the same message error on the network settings (i.e. IP by default, cannot connect to the internet). Therefore the second time around I kept my profile as backup and re-created a new one plus a guest one.
The airport utility then signaled to issues remaining:
1) Internet access was cut - this I solved by simply reseting the cable modem
2) There were no DNS Servers - I simply copied the ones I had from the previous setup and it worked
I did have AppleCare....
I'm online again and I hope for good.
Thanks a lot
PS. a small tip - I made captures of all my settings in Network settings, Airport Utility and Network utility using Grab in case of ... if anything it is just handy to get back settings that your are missing when setting up a new configuration

I have an older Airport Base Snow that I gave to my brother to use for his apartment. It's connected to a cable modem and I have a network but it is not protected. How do I set a password? There is no computer in this setup, just an iPad

I Have an older Snow Airport Base that I gave to my brother to use in his apartment. It is connected to a cable router. I have a network established but it is not secure. How do I password protect this network? There is no computer in this setup, only an iPad. Thanks!

If this base station is actually the "snow" then you will need a Mac or PC that can run a version of the AirPort Utility that can administer this "very old" 802.11b base station. You won't be able to do so with an iOS device or Mac running Lion or newer OS.

Lost connection to my cable modem

Ok people I am hoping that you can help me out here. Yesterday my Time Capsule stop connecting to the internet through the cable modem. Called Comcast assuming it was there service. After an extensive check process we determined that service and the cable modem were working correctly. So then i proceeded to call Apple Support. Again through the check process of all the peices that are connected to finally determine that the TC was the culprit. I took the TC back to the Apple Store and they graciously exchanged it out. I took it back home hooked it up and it we are back to where I started, the new TC is responding exactly like the old unit. So my cable modem is a Motorala SB6141 and I have sevice through Comcast. The cable modem and TC have been working together for 6 months before this happened, with no new hardware added in the last three months. The cable modem when connected to the computer (Mac or Windows) directly can connect to the internet. I even tried connecting the cable modem to a AirPort Express and it had the same effect as the TC. So does anybody have any suggestions?

The SB6141 is problematic with the Airport routers.
There is some issue of compatibility.. it is hard to figure out.
If you replace the cable modem with a different one it will be more likely to work. I am not in the US so just look at posts about the more compatible models. Or simply use another brand router, and set the TC in bridge and use it as wireless and backup target.
I do think you can get some improvement in some cases using a crossover cable. I have made that recommendation and it has worked for people.
Or a small 10/100 switch between the two .. cable modem and TC.
https://discussions.apple.com/message/23236139?ac_cid=tw123456#23236139
You need to power cycle the modem whenever you change router.. I am guessing you are doing that.. but just to be sure.. at least 15-30min is required with some ISP.. 5min for others.. some are much longer..
The ISP must drop your previously connected equipment to pick up the new one.

Want to connect wrt54g to cable modem

Internet connection lost using hughesnet modem and Airport in Time Capsule

I recently got Hughesnet which is the only available high speed internet at my home.
The problem I'm having is that my wireless connectivity is lost to all devices requiring me to unplug and plug back in my Airport...at which time I have internet again until it goes out again.
The problem does not appear to be an actual lost internet connection through my Hughesnet modem.
Any thoughts on how to fix this problem? I have reset my Airport to factory settings and named it TCwireless for simplicity.
