Switching From DSL to Cable Modem

I am about to switch from a DSL service to a faster Cable Modem service using my local provider's (Time Warner Roadrunner) self install kit. I was hoping that you experts could give me some advice before I begin the conversion.
Currently, my DSL modem connects to Airport Extreme, then Airport Extreme to my iMAC.
My question is whether to first plug in the ethernet cable from the new cable modem directly into the iMAC and make sure that the internet is accessible. Then power off all devices, hook up Airport Extreme back into the chain and try again.
Or right from the start, should I just plug the new cable modem into Airport Extreme and see if the iMAC sees the internet automatically?
Any step by step advise would be appreciated.

My question is whether to first plug in the ethernet cable from the new cable modem directly into the iMAC and make sure that the internet is accessible. Then power off all devices, hook up Airport Extreme back into the chain and try again.
You pretty much summed it up.
I would do the following in order:
o Power down the DSL modem, AirPort Extreme Base Station (AEBS), and iMac. Order is not critical.
o Install the new cable modem and connect the iMac directly to it using an Ethernet cable.
o Power-on the cable modem; wait at least 10-15 minutes.
o Power-on the iMac, and then, check for Internet connectivity.
o Power down the iMac, and then, the cable modem.
o Disconnect the iMac from the modem; connect an Ethernet cable between the modem and the WAN port of the AEBS; connect another Ethernet cable between the LAN port of the AEBS and the iMac.
o Power-on the cable modem; wait at least 10-15 minutes.
o Power-on the AEBS; wait at least 5 minutes.
o Power-on the iMac, and then, check for Internet connectivity.

Switched from DSL to cable modem. My Airport light won't turn green. Keeps blinking orange. No wireless now and can't connect to more than one computer! ?????

Hmmmm.
If you reset the AirPort Extreme by holding in the reset button for 9-10 seconds and then releasing, the AirPort should be back in default settings which would allow mutliple computers to connect to the LAN ports on the AirPort.
Power off the cable modem for now and leave it off at least 15 minutes.
With the AirPort Extreme still powered on, hold in the rest button on the back for 9-10 seconds and release. Allow a full minute for the AirPort Extreme to restart to a slow, blinking abmer light.
Then, power off the AirPort Extreme.
Check to make sure that the Ethernet cable from the modem is connected to the WAN "O" port on the AirPort Extreme.
After the modem has been powered off for at least 15 minutes, power it up and let it run for 5 minutes by itself.
Now, power up the AirPort Exteme and let it run for 2-3 minutes
Open Macintosh HD > Applications > Utilities > AirPort Utility
Connect an Ethernet cable from your Mac to one of the LAN <-> ports on the AirPort Express
Click on the AirPort Exteme, then click Continue to follow the guided setup tp configure the AirPort Extreme. You can use the same wireless network name, password, etc that you used before, or set up a new name and password, etc.

Switched from DSL to CABLE. WRT54G Wireless Router stopped working.

When I switched from DSL to CABLE, my WRT54G Wireless Router stopped working. I am not able to access the router page (192.168.1.1) Also, when I use the set up CD for re-installation, the wizard aborts in the middle saying it can not connect.
I appreciate any help to resolve this problem.
P.S. The router acts like a one-port wired router.

Here is my favorite method for resetting a router to factory defaults, and trying to get it working again.
To reset your router to factory defaults, use the following procedure:
1) Power down all computers, the router, and the modem, and unplug them from the wall.
2) Disconnect all wires from the router.
3) Power up the router and allow it to fully boot (1-2 minutes).
4) Press and hold the reset button for 30 seconds, then release it, then let the router reset and reboot (2-3 minutes).
5) Power down the router.
6) Connect one computer by wire to port 1 on the router (NOT to the internet port).
7) Power up the router and allow it to fully boot (1-2 minutes).
8) Power up the computer (if the computer has a wireless card, make sure it is off).
9) Try to ping the router. To do this, click the "Start" button > All Programs > Accessories > Command Prompt. A black DOS box will appear. Enter the following: "ping 192.168.1.1" (no quotes), and hit the Enter key. You will see 3 or 4 lines that start either with "Reply from ... " or "Request timed out." If you see "Reply from ...", your computer has found your router.
10) Open your browser and point it to 192.168.1.1. This will take you to your router's login page. Leave the user name blank, and in the password field, enter "admin" (with no quotes). This will take you to your router setup page. Note the version number of your firmware (usually listed near upper right corner of screen). Exit your browser.
If you get this far without problems, try the setup disk (or setup the router manually, if you prefer), and see if you can get your router setup and working.
If you cannot get "Reply from ..." in step 9 above, your router is dead.
If you get a reply in step 9, but cannot complete step 10, then either your router is dead or the firmware is corrupt. In this case, use the Linksys tftp.exe program to try to reload your router with the latest firmware. After reloading the firmware, repeat the above procedure starting with step 1.
If you need additional help, please state your ISP, the make and model of your modem, your router's firmware version, and the results of steps 9 and 10. Also, if you get any error messages, copy them exactly and report back.
Please let me know how things turn out for you.

Can't access PIX 501 after switch from dsl to cable

Hi--
I have two small offices and recently switched from dsl to cable internet. the two pix501 f/w units worked fine on dsl, but for the life of me I cannot even access the units now from the inside as I was able to do before when on dsl signal. I know I need to change the configuration from PPPoe to DHCP, but I can't get access to do it.
Any suggestions?
I believe I have 6.2 software, but I'm not sure. The Inside address is 10.8.6.1 now.
thanks--jb

Jorge--
I did have the Pix connected to router, 192 168.1.1 for convenience, so I could still get internet wirelessly without having to do lots of wire unplugging and plugging.
I have since changed to topology of comcast modem connected directly to pix which in turn connects directly to laptop.
In this configuration, laptop pings 10.8.6.1 ok, but pix has no connectivity to comcast.
When laptop connected directly to comcast modem,(ie pix removed) the ipconfig /all from laptop reads the following from comcast:

Switched from DSL to cable and now can't find apple tv in itunesdevice list

I just switched from DSL to Cable and now for whatever reason I cannot find my apple tv in the itunes device list on my desktop computer. If I use another laptop through the same wireless router I can see the apple tv no problem. My apple tv can see my wireless router and connect to the internet and watch youtube/trailers/etc.
I have tried restoring the apple tv, and have also tried uninstalling and reinstalling the itunes on the desktop. I also reset the wireless router...none of the above seem to work. any suggestions would be greatly appreciated as this has been crazy frustrating...thanks in advance.

If you have an AirPort Extreme or a Time Capsule, you need to use the AirPort utility to access it. Otherwise, your router has a control panel that you can access by entering the router's IP address into your web browser. You'll have to check your router's documentation for the default login name and password, but it's often admin admin or root root (which is why you should at least change the password as soon as possible).

Switched from DSL to cable, need help getting TC back on line.

I just switched from dsl to a cable modem to access the internet and my service provider doesn't offer support for my TC. Where can I find out how to change my settings (I guess from PPPOE to DHCP) to allow internet access from my wireless network? It seems like a matter of plugging the right numbers into the right place but I don't know where to find the numbers or where to put them exactly. Any help is appreciated.

Hello Sivad72. Welcome to the Apple Discussions!
I suggest that you first perform a "hard" reset on your Time Capsule (TC). Then, perform a complete power recycle of your network components to get them "talking" again.
Power Recycling Steps
1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
3. Perform a complete power recycle of your network components as follows:
o Power-off the modem, TC, & computer(s); Wait at least 5 minutes.
o Power-on the modem; Wait at least 5 minutes.
o Power-on the TC; Wait at least 5 minutes.
o Power-on the computer(s)
4. Contact your ISP to have them perform a "modem reset."

Can't get router working after switching from DSL to Cable broadband???

I have a WRT54G v.5
I just switched from dsl service to cable broadband. I can't get my router to work. I hooked it back up just as the dsl modem used to be. there is an ethernet cable that goes from the cable modem to the router. then an eithernet cable that goes from the router to the computer. this does not work. If I just take the router out of the loop and run an eithernet cable straight from the cable modem to the computer it works fine. so the cable internet service is working fine up to the modem. The router is the problem. I have restarted both the computer and the router. so that rules that out. can you help me?

Open the setup page of the router by launching an Internet Explorer Browser and type the address bar, 192.168.1.1 and press enter. When it prompts for the username and password, leave the username field empty and provide password as admin and click on ok.On the main setup page the ""Internet Connection Type"" should be on ""Obtain IP Automatically - DHCP “. Click on the Save Settings button.Now click on the sub tab ""MAC address clone"".- Click on enable.Click Clone & click save settings
Check WAN Ip on Status page of router .... If getting Valid Ip .... try going online...If not ... power cycle for 4-5 minutes & then, try going online.

Switched from DSL to cable, can't connect through Airport Extreme.

Network help required!! I switched from my spotty, poor DSL hookup this afternoon, to a new faster cable hookup. I have 5 devices to attach through an airport extreme. All 5, ( 2 iMacs 1 iPhone 1 iPad all wireless 1 XBox wired ) on dsl, hooked up this morning, now on cable, only 1 at a time. And only after restarting the cable modem. The only part of my network that changed is the isp...thoughts?
I have the cable to the modem, ethernet to AE, wireless signal to iDevices, ethernet to XBox.

Switched from DSL to Cable, Can't connect to the internet

After switching to cable modem (Motorola SB5120 SURFboard) from DSL, I can't connect to the internet using my airport express. Everything is green - modem and airport, and the signal on my computer looks like I have full access, but there is a scrolling message... looking for PPPoe host. I have unplugged everything and restarted per the instructions on this site, but get the same result every time. My computer connects just fine using direct connection to the modem. I saw a download for a firm ware update for the express, but don't know how to apply that, either. Any help out there?
Thanks!

Hello mom2gr82. Welcome to the Apple Discussions!
Let's double-check your AirPort Express Base Station's (AX) settings...
AirPort Express Base Station Setup (AX) w/High-Speed Cable Modem
Perform a "factory default" reset of the AX
o (ref: http://docs.info.apple.com/article.html?artnum=108044)
Modem/Router Power ReCycling
o Power-off the Cable modem, AX, & computer(s); Wait at least 30 minutes.
o Power-on the Cable modem; Wait at least 15 minutes.
o Power-on the AX; Wait at least 5 minutes.
o Power-on the computer(s)
Setup the AX
Connect to the AX's wireless network, and then, using the AirPort Admin Utility, try these settings:
AirPort tab
o Base Station Name: <whatever you wish or use the default>
o AirPort Network Name: <whatever you wish or use the default>
o Create a closed network (unchecked)
o Wireless Security: Not enabled
o Channel: Automatic
o Mode: 802.11b/g Compatible
Internet tab
o Connect Using: Ethernet
o Configure: Using DHCP
o WAN Ethernet Port: Automatic
Network tab
o Distribute IP addresses (checked)
o Share a single IP address (using DHCP & NAT) (enabled)
Once you verified that you can get Internet access for all of your computers, you should secure your wireless network. To do so, I suggest that you make these changes:
Change Wireless Security
o Wireless Security: WPA Personal or WPA2 Personal
o Encryption Type: WPA and WPA2
Base Station Options - WAN Ethernet Port
o Enable Ethernet Port (checked)
o Enable SNMP Access (unchecked)
o Enable Remote Configuration (unchecked)
o Enable Remote Printer Access (unchecked)

Have airport snow (duel) and have switched from DSL to Cable , problems .

Hi all my problem is that since the switch I now use a Moto surfboard 5101 and the activity light just stays blinking both on the snow and on the modem . If I turn the airport off the activity light on the modem stops , plug in the airport and it starts blinking . I can get on the net but this bothers me as it didn't do this when I had DSL with a westell modem . I have uploaded the default software to the airport and that did nothing . There are no other computers using or even turned on . The laptop is turned off and still the activity lights on both are blinking like crazy . Also there is no one leaching my wifi , this all started when I installed the cable modem . Has anyone had this experience ?

It's always a good idea to do a complete power-recycle of all of your network components when making changes.
Try the following, in order, checking for Internet access after each step, or until resolved:
1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
3. Perform a complete power recycle of your network components as follows:
Modem/Router Power Recycling - Quick
o Power-off the modem, AirPort Base Station (ABS), & computer(s); Wait at least 5 minutes.
o Power-on the modem; Wait at least 5 minutes.
o Power-on the ABS; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the modem, ABS, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the modem; Wait at least 15 minutes.
o Power-on the ABS; Wait at least 5 minutes.
o Power-on the computer(s)
4. Contact your ISP to have them perform a "modem reset."

Switch DSL to cable modem causes Time Capsule "Flash on Activity" nonstop?

I recently switched from DSL to Cable internet. After I switched, the green light on the Time Capsule CONSTANTLY flashes -- as if there's constant activity. The Time Capsule was set to "Flash on Activity" when it was attached to the previous DSL modem and it only flashed when there was obvious activity. Now it flashes constantly green -- even when all devices are turned off.
I have ruled out anyone lurking on my wifi. Even after resetting the wireless password, the green light again immediately starts flashing constantly.
I've searched and searched the Internets for anyone with a similar issue, but have yet to find one.
Should I be concerned? Should I just let it flash? I like to see when there's activity on the Time Capsule, but now watching it flash all the time just makes me paranoid.
P.S. It also does the same thing when hooked up to an 802.11n AirPort.
Thoughts?

It's distressing to think that there are constant break-in attempts. I assume that's what the firewall is for, so I guess I'm ok.
You should be OK. Not all of it is break-in attempts. A lot of it is just your neighbors' computers sending packets to advertise that they have a file share open. Or a printer. Before I got a router/firewall, I was really surprised at how many people had wide open file shares or shared printers. And some traffic will be from Comcast, too.
I'm not sure if I'm port forwarding. I just have a typical Time Capsule wifi setup.
You probably aren't if you're not sure. It's definitely not set up that way out of the box. Port forwarding would be if you wanted to allow a server on a computer inside your home network. I forward a port so I can log into the UNIX shell on my computer from my work.
The main two things you want to look at are to open the AirPort Utility and look at the "AirPort" section's "Time Capsule" page. There's a checkbox for "Allow setup over WAN." You want that to be unchecked (blank). And if you go to the "Advanced" page, under "Logging & Statstics" there's a setting for "Allow SNMP" and a sub-setting for "Allow SNMP over WAN." It's most critical that "Allow SNMP over WAN" also be unchecked (blank). Those two settings could allow someone from outside your home network to mess with the Time Capsule. The other thing is to make sure you have a good password both to join the network and to actually administer your Time Capsule.
The thing that confuses me the most about the flashing on activity issue is that millions of people have comcast cable internet and I assume many thousands use a Time Capsule or an Airport for wifi and yet I have been completely unable to find any mention of anyone having this same problem.
I've seen it mentioned in cable-modem specific forums, like the Comcast forums or DSL Reports. I've had a cable modem for close to 15 years. For the first couple of years, I didn't see the activity light blink like it does now. But that changed not long after I got the cable modem, maybe when they replaced an old one with a different brand.
I remember seeing quite a few posts about it then, but I suppose people just got used to it after a while. And it's not limited to the Time Capsule: I've had three or four other firewall/router devices from other manufacturers, and they all had the blinking activity lights, too.

Welcome to the discussion area!
+Now it flashes constantly green -- even when all devices are turned off.+
If you are including the modem here, then you have an internal issue within the Time Capsule.
If not, now you know that the cable company is always sending stuff down the line. You might want to consider setting the light back to Always On, knowing that it will be flashing constantly anyway.

DSL to Cable Modem switch - now Airport express doesn't work

I just switched from DSL to Cable and now connecting to the internet via my Airport express doesn't work. It's fine direct connecting via ethernet.
Is there a known issue? I've tried various things but no dice.
Are my Airport expresses now married to the older modem?
Any help would be appreciated.

Okay I got a new Airport extreme since there was a chance that the new modem and the expresses weren't 100% compatible and the Extreme worked almost out of the box.
Truth is, I might have just had to hold down the reset buttons on the expresses longer so that they would revert to the manufacturer's default and they might have become functional since I did that later and my old expresses are now connected to the home network.
For anyone else with this issue, before giving up or if you don't need an excuse to buy an extreme, hold that airport reset button in a good two minutes before and then another two during the plug-in and you might get lucky.
Thanks.

I don't have a DSL or cable modem to access the Internet ... just a mobile WiFi (there is no cable available at our house). How do I connect my Time Capsule to the Internet via the mobile WiFi?

I don't have a DSL or cable modem to access the Internet ... just a mobile WiFi (there is no cable available at our house and the mobile WiFi is our only option). How do I connect my Time Capsule to the Internet via the mobile WiFi?

LOL!!
I am in Australia and the ISP... I think both the main ones would fit your description to a T.. big T in particular.
Your router is really unsuitable.. if it is only wireless and no ethernet.. just buy an ethernet one.
Do a search on ebay.. 3g router.
But you can get the TC to join a wireless network.
It is a non-standard setup that Apple will not support.. the option is hidden.
If you are on Lion download the 5.6 utility. Go to the wireless set up page and hold down the option key whilst selecting wireless mode.. a new option, join will appear. You can then put in the ssid and passkey of the 3g router.
But please note the end result of this setup..
very slow speed. The TC is now a second wireless hop from your clients.. this will halve the speed.
In this mode the ethernet are deactived.. for reasons only Apple know, they decided you should not use ethernet when doing this.

Swapped from DSL to Cable using befw11s4

I recently swapped from DSL to Cable and now I am running into not being able to connect to the internet though the router. I have run all the advisor answers from cloning the MAC address to all the power-off procedures. I can connect to the router through 192.168.1.1 and that is it. I cannot connect through the router. Help please!Message Edited by jb4wc on 03-19-200702:04 PM

Yeah... just reconfigure the router from scratch... to make it is back to it's default settings just press the reset button at the back of the router for like 20-30 seconds. Then unplug the power of the router for 10 seconds and plug it back in.
Then so that you wouldn't have to do much to reconfigure the router... connect a PC to the modem and download a software called EasyLink Connect from www.linksys.com/easy Run this software... just follow the instructions and you should be good to go.
