Cable modem and WRT54G

I had to change my cable modem.  After replacing the modem, the WRT54G seems to connect but
fails to obtain an IP address.  When I connect a computer directly to the modem I have no problem
connecting to DHCP.  What am I doing wrong?

Never mind.  Went back and read the very helpful general instructions.
I think this MAC cloning issue is new, previously I had everything
working with MAC cloning disabled. 
Be that as it may, following instructions fixed it, thanks for having those
up there and sorry for cluttering up the forum.  If there were a way to delete
a post I would..

  • 150ft Cat5e between Cable modem and WRT54g...Shouldn't it work?

    I have a WRT54g that I am trying to connect to my cable modem with an approx.150ft Cat 5e cable. I can connect my laptop to the modem with this cable and it works. (It does take a few extra seconds to get a link). When I try to connect the router to the modem, it does not ever successfully link. Any suggestions?

    well....reducing the cable length to 100 fts and check whether this makes any difference..

  • How do I set up Airport Extreme with cable modem and router?

    Hi--
    I'm having a house built and all of the wiring for TV, phone, and internet will be centralized in a closet. The cable modem can be placed there as well. In one room in the basement I want to use my Airport Extreme for my iMac and USB external hard drives. In another location of the basement, I'd like to set up a Time Capsule for another desktop and USB printer. If the cat5e comes out of the wall at each location, I "think" I need a router at the closet location. I also thought I might need an Airport Express upstairs on first or second floor to boost signal for my laptop. The house isn't that big so maybe that's overkill. So beyond the router question, do I want to set up a roaming network and have the Airport Express connected via ethernet or just wireless if the thought is that I need this? Finally, if I should connect cable modem to router to Airport Extreme, Time Capsule, etc., in what order and ports does the equipment get connected? Many thanks!!

    Welcome to the discussions, Forum Girl!
    It would be best to position the cable modem and main router in the central location like the closet if possible. The other devices would connect via ethernet to the wall jacks in each room.
    If you could setup a "roaming" wireless network as you mention, this will give you better wireless performance and coverage. This is the way commercial establishments like airports, businesses, etc. are configured for wireless.
    The order of connection would go something like this: ethernet connection > cable modem >main router>devices. Devices could be computers, routers, a backup device, etc. Since the Extreme has only 3 LAN ports for ethernet connections, you will also need to plan to install an "ethernet switch" near the location of the main router to provide enough ethernet jacks. If you are planning to use DirectTV, etc or your audio/video devices require ethernet connections (most new products do for updates and extra features), be sure to plan for that as well.
    Make sure that CAT5e or CAT6 wiring is run so you will be able to take advantage of faster gigabit speeds.
    Finally, it would be a good idea to work with an IT specialist to go over your plans to make sure all the bases are covered. This would be money well spent.

  • My airport is not connecting to the internet. I have a cable modem. and i'm on the internet now connected directly to the modem. what can i do?

    my airport is not connecting to the internet. I have a cable modem. and i'm on the internet now connected directly to the modem. what can i do?

    I would recommend that you do the following as a minimum:
    Power-down the modem, AirPort base station, and computer(s).
    Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
    Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
    Power-up your computer(s).
    If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
    Disconnect the AirPort base station from the Internet broadband modem.
    While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
    After the base station resets, go ahead and power it back down.
    Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
    Continue with step 2 in the first set of steps.
    In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

  • I had to replace my cable modem and now my Time Capsule only talks to just the one Mac Air.  My other wifi devices (another Mac Air, iPad, and iPhone) can't get on the wifi.  Any suggestions?

    I recently replaced my cable modem and now my Time Capsule only works with the one Mac Air and not my other devices (another Mac Air, iPad, and iPhone).  Any suggestions?

    It sounds like you have gone from a cable router with the TC bridged to a cable modem with no router.. so the first device to connect pick up the IP address. Did the cable company give you the same model?? Check if it is a pure modem or a modem router.. and what the last one was.
    Anyway.. you should redo the setup.. do you have any computer with ethernet?? Did you buy a USB to ethernet adapter for one of your airs.. very hard to do setup without ethernet.
    Also download the new utility.. with the old style.

    If you happen to be on Lion.
    Redo the setup and make sure you setup correctly to router mode if the cable modem has no router or bridge mode if it is a router.

  • Should Iplace my ethernet switch between cable modem and airport extreme?

    I'm looking for the best placement of an ethernet switch in my home network.
    Should I place it "between" my cable modem and my AEBS or connect it to the output from my AEBS?
    The current placement is connected to one of the AEBS outputs.
    I'm attempting to set up an old AE (802.11 a/g from 2004) with a different network name than my home network, that I'm trying to set up for a college dorm network and each time I plug the AE to the switch to confirm its functionality, my network gets a little confused.
    Help appreciated.
    Regards,
    jim P.

    Should I place it "between" my cable modem and my AEBS or connect it to the output from my AEBS?
    This all depends on whether you have a simple modem.....or.....a modem/router or gateway combination device.
    If  you have a simple modem, you cannot place the switch between the modem and the AEBS. The reason for this is that the modem can only deliver one valid IP address and it will be a matter of chance as to which of the devices connected to the switch receives it. The other device connected to the switch will not be able to access the Internet.
    If you have a modem/router or gateway type of device, you can place the switch after the modem/router and before the AEBS if you wish, although there is really no advantage to doing so unless this makes things easier for you in terms of hook up.
    If none of this makes much sense at all to you, leave the switch in its current location connected to one of the LAN <-> ports on the AEBS since that setup will work correctly no matter what type of "modem" that you might have.

  • Connecting AX and ethernet wire to cable modem (and ARD).

    Hi all,
    This has to be easy, but after 10 minutes of searching, I can't readily find the answer.
    I have a cable modem (with one port) which works with my Macbook just fine. I plugged in an Airport Express (and used wireless only) and it works fine also, EXCEPT:
    When using Apple Remote Desktop (the latest version) to control the Macs at my office, the status of all remote Macs is: Screen Sharing. When I connect to a remote system, I can see and control that Mac, but I can't copy anything either way (from remote to local or visa-versa).
    When connected to the cable modem with an ethernet cable, everything works fine.
    SO, I would like to connect maybe a 3 port hub to the cable modem and use both the ethernet cable and the AX (for other computers & iPhone) at the same time. Will this work? Can someone suggest a good hub/switch for this if it does?
    Secondly, is there a way to use ARD on a wireless computer? It would be nice to go to a hot-spot and control my remote Macs.
    Thanks.

    SO, I would like to connect maybe a 3 port hub to the cable modem and use both the ethernet cable and the AX (for other computers & iPhone) at the same time. Will this work?
    No. You need a router not an Ethernet hub (or switch). The AX can't do the job because it only has a single Ethernet port.
    Secondly, is there a way to use ARD on a wireless computer?
    Sure. It works just like any other computer behind a router. You must configure the computer to be at a fixed IP address and then forward/map the appropriate ports through the router to the computer.

  • Cable modem and AX seem not to talk... Help?

    I used to own a set up with an ax and cable modem and ibook. I sold all of it after my ibook crashed and burned. My gf and I recently moved in together and she has a Dell laptop running xp. We just got cable service and they gave us a new modem and I went and picked up another ax. When I plug her laptop directly to the modem, it picks up the internet just fine. When I have it search for the wireless connection, it will pick up the AX and connect... BUT, for some reason the modem and the AX do not want to communicate and I can't get internet sent through the AX. Is this a common problem? I've tried power cycling, switchin out ethernet cables, changing some of the preferences. Maybe I missed a step? I just remember my last set up was Step one, plug in. Step two, connect. Suggestions?

    Was on the phone with apple. Turns out it was a faulty ax. The ethernet jack didnt work. I took it back to CompUSA and got a new one. It set up in less than 5 minutes.

  • What is the proper config for the Airport Extreme when a Voice over IP device is between the cable modem and the router.

    What is the proper config for the Airport Extreme when a Voice over IP device is between the cable modem and the router.  Its a VoIPo device. The cable modem is connected to the VoIP WAN port and the LAN port on the device feeds the Airport Extreme.  The VOIP is working fine, and my Mac are getting 10. addresses from the Airport Extreme.  But I do get confict messages and lose my connection periodicaly.  Looking for help.

    Its a VoIPo device.
    Per chance, is this device the Grandstream HT502?

  • The connection between your access point, router, or cable modem and the Internet is broken.

    At random points throughout my laptop usage, I randomly disconnect from the internet and receive these 2 messages:
    1. The connection between your access point, router, or cable modem and the Internet is broken.
    2. The default gateway is not available.
    It fixes the issue for a short period of time, but constantly happens. This is really starting to annoy me. I have no problems on any other internet, and other people i live with are connected with no issues to the internet. I have tried a number of solutions
    online that has "worked" for others to no success such as resetting the router, fooling around with command prompt, and changing the performance settings to not drop internet when low on power. Does anyone have a solution for my technical problems?
    I am running Windows 8.1 on a Lenovo ideapad that is less than a year old. I will be honest I am not a very knowledgeable person when it comes to computers, so please use simplified explanations.

  • SurfBoard Cable Modems and OS X

    I just wanted to post a message about my findings and my solution to the Mototrola SurfBoard 5101 Cable modem. I use comcast as my ISP. I was using an old COM21 modem. I was getting around 4300 KBPS on a broadband test from Speakeasy. Since Comcast was starting this PowerBoost, I needed a DOCSIS 1.1 compliant modem and the COM21 modem wasn't. I went to my localComcast office to switch it out since I was leasing one. They gave me a SurfBoard 5101. I already saw the postings and the articles on Macfixit.com. I tried the modem and was getting 2700 Kbps. I tried everything to get the speed better. Connecting my iMac directly to the modem. Tweaking TCP settings.
    I called Comcast and they said they never heard of the issue. I explained of all the postings I saw and the artiles also. She said she believed me but didn't know of the problem. I found one article talking about using other modems. The newer Surfboard 5120 modem said was better but had issues with Comcast's network and would disconnect. They said the linksys cable modem wasn't any better. The one they said was the best was the DLINK DCM-202. It was 49.95 on sale at Best Buy. I thought, what the ****, I'll try it. If it didn't work I can return it. I got it home. Installed it. Provisioned it and ran the Speakeasy tests. I was blown away. I got a speed of 9049 Kbps. Just ran the test while typing this.
    So if anyone else having this issue, I would return the cable modem back to Comcast and ask for a non Motorola modem. That's the advice the Comcast rep told me. Or just buy the DLINK modem. I can now return the 5101 modem and stop leasing it and finally I get my full speed.
    Thanks!!!

    I used telewest's 10 megabit cable service here in the London UK for about a year. they issued me with a motorola surboard SB 5100i and this worked perfectly. I could get the max download speed of 1.2 megabytes per second and an upload speed of 400k.
    I used the cable modem with a linksys wrt54gs router and has not bandwidth issues at all.
    I did not have to tweak any network settings on my Macs.

  • Can i use one router connected to my cable modem and another....

    can i use one router to connect to my cable modem them have another (not connected to a modem) and a wireless reciver so i can plug my xbox 360 into it?

     Yes you can do that ... but you need to configure the computer connect to the Router using Cable ....
    Afterwards ... you can work on mutiple computers ...

  • Vonage between cable modem and Airport Express is a problem

    I have my Comcast cable modem connected via Ethernet to the Vonage box which is connected via Ethernet cable to my Airport Express. When I try to connect wirelessly via my Powerbook it's a crapshoot whether or not I can connect to the internet. Mostly the quality is very poor if you can connect at all. If I cut the Vonage out of the equation hooking the cable modem to the Airport Express it works perfect. So Vonage is my problem and I need to change some settings either with my computer or my Airport Express, but which ones? I've been given several different ideas from the information I've sifted through (i.e. change the DNS, change the sharing prefs, get a hard wired router). Oddly enough an old HP computer I have in the basement connected to the internet via another Airport Express has no problems with connection at all. If someone could let me know which of these fixes I am preparing to try would work the best I would appreciate it.

    Interesting. So you have two Airport Express devices configured into a WDS, with the one upstairs functioning as the main base station and the one downstairs functioning as a remote base station. And your PC downstairs connected to the remote base station has no problems connecting to the internet. Is that PC cabled to the Airport Express, or does it connect wirelessly to the remote Airport Express?
    What happens if you bring the Powerbook downstairs to where the PC now resides. Does the Powerbook then get the same great internet connection as the PC?
