EA2700 not recognized by Cable Modem

I have an EA2700 (fimware "classic" 1.0.14.129982) that used to work perfectly fine with a Comcast cable modem.  I just recently switched to Charter with an Arris TM902 modem and that's where the problems started.  The cable modem will not recognize my router.  I have to plug in a computer into the cable model when it starts up.  Then I need to clone the MAC address and restart the router (after disconnecting the computer).  Why isn't the cable modem recognizing the router when I restart it?  I guess this could work if it would be a one time thing but I had to power-cycle the modem and it stopped recognizing the router even with the cloned MAC address.  So I had to do the whole spiel again.
Is there any way to make this work easier?  Should I update my router's firmware to the "smart" one?
Any suggestions are welcome ...
Thanks,
Joe

Since you are changing ISP’s and using a new modem, best to reset your router back to factory settings. Press and hold its reset button down for 15 seconds and wait for the lights to stabilize. It is okay to enable the MAC Address Clone since most Cable Internet Service Providers for a router like you have would require it in order for the internet to work. Upgrading to the Cloud firmware is fine, too, that you will be able to take advantage as well of accessing your router from a remote location.

  • Why does my airport extreme not recognize my cable modem anymore?

    Why does my airport extreme not recognize my cable modem anymore?

    Have you tried resetting the modem? Power it down and let it rest a moment, then power it back up again.
    Also, some ISPs require physically detaching their cable from the modem for it to be fully reset. Literally unscrew it from the modem. Try that, in conjunction with powering it down.
    Don't do anything with your Extreme, other than powering it down too, in the event the modem reset does not help. Reconfiguring it may be necessary but this is not justified quite yet.

  • Time Capsule not working with cable modem

    I have a WebStar modem using Cox cable internet. When I plug the ethernet cable into my Macbook directly out of the modem, I have internet. When I plug the Ethernet cable into my Time Capsule - I have no internet and the lights on the modem do not flash. The modem is not recognizing the TC or the TC is not recognizing the modem. Any solutions??? Please help.....

    It's the former.
    Power everything down, including the modem. While it's powered down connect the TC's WAN port to the modem. After a few moments of peaceful contemplation, power up the modem and then the TC.
    You should then be able to configure the TC with Airport Utility, if you haven't already done so. If you can't, and you need to reach the outside world again, resist the temptation to connect your computer directly to the cable modem. Connect a computer to the TC's LAN port instead.
    Here's the applicable explanation from Apple:
    *You've done everything right, but still can't connect to the Internet. Why?*
    It's because the modem locked onto your iMac, and it will ignore anything else you plug into it until it's been reset. If you were to plug the iMac back into the modem, it would still connect to the Internet.
    Fortunately, resetting a broadband modem is usually very easy -- just unplug its power supply, wait a moment, and plug it back in. After its indicator lights have gone through their startup routine, you should do the same to the AirPort base station.
    Odds are that you can connect to the Internet now.

  • Airport Extreme Base Station not cooperating with Cable Modem

    The non-specific issues are by far the most frustrating and I can't make any sense of this. To be fair, this might not be a AEBS issue as much as a ISP issue, but any suggestions are much appreciated.
    History: My setup has worked great for about 6 months, but recently I've been having intermittent problems (described below) that have been getting progressively worse and more frequent. The issues have not changed in relationship to firmware/software updates for the AEBS and airport utility.
    Setup: Cable Modem (Time Warner Kansas City is ISP) --> AEBS (A1143 on the latest firmware) --> periodic wireless connection to imac, macbook pro and 2 iphones. A Time Machine (hard drive) is also connected to the AEBS via USB.
    Symptoms:
    -Intermittent disconnects and slowdowns over wireless
    -Wired connections are completely unaffected.
    -Loss of wireless internet connectivity is consistent through all devices.
    -Time machine is unavailable when the internet is not accessible.
    -During disconnects sometimes the router doesn't even appear, sometimes I can connect but can't reach my time machine or the internet, sometimes it won't accept my password and sometimes it times-out.
    Sounds like the wireless transmitter is going out on the AEBS or something, right? Well, Apple was kind enough to replace my AEBS under warranty to try to solve this problem, but it hasn't gone away.
    Could this be an issue with my ISP not distributing IP address properly or something? I'm not really very savvy with the way all that works.
    Thanks for your help with this mess.

    Its gotta be the surrounding interference issue. I found a macworld article that refers to testing the different channels in the 2.4gHz range and finding some completely unusable (as you mention). If I didn't have a couple iPhones that can't run 5gHz, I'd certainly bump up to that because apparently that's where the performance is!
    Here's a link to the article, although it's mostly a review, though information within is pertinent to our issue.

  • Router not communicating with cable modem

    I have a befw11s4 ver 3 router that has functioned well for over 5 years and the other day we had a lightning strike that wiped out our cable modem.  The modem was replaced but the router seems to have a problem.  First, the power led does not lite up but the WLAN Act and WLAN link led's are ok.(green)  When I try to setup the router with the CD the I get a message that the router will not communicate with the internet and stops.  If you connect the computer directly to a access point the led's (link/act & full/col) and you can ping and talk to it.
    So, is there a way to determine if the router was destroyed by the lighgtning strike or if the router just needs to be reloaded?  Thanks in advance for your replies.

    Press and hold the reset button for 60 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now check if the Power Light is ON on the router or not...? If there is solid power light the, you can reconfigure your router....If there is still no power light then check if you are getting any ip address from the router....
    Click Start >> All Programs >> Accessories >> Command Prompt...A black box will appear(Command Prompt)...In the Command Prompt window type ipconfig and press 'Enter'...Look for Ethernet Adapter Local Area Connection IP Address , Subnet Mask and Default Gateway...
    IP Address should be 192.168.1.x, Subnet Mask : 255.255.255.0, Default Gateway : 192.168.1.1 (assuming your router is 192.168.1.1)...
    If you get the above mentioned IP Address, Subnet and Gateway Address then you should ping the Gateway, type ping 192.168.1.1 and press Enter..If you are getting 4 replies then...you can manually setupyour router...Ifyou are not getting the replies then, you router must have gone bad.

  • Airport Express not working with cable modem

    I have an airport express that has been working perfectly.  I changed my internet provider and it suddently won't work -- no dns, no internet--even though other devices (including apple tv) are connecting with no problem.  [the cable modem (motorola) runs through a router to apple tv and the airport express.]  I have reviewed everything here and nothing is helping (powered down, disconnected everything, etc)  I am at a complete loss.  Please HELP. 

    Configuration is simple if you start from a factory default condition.  Connect the main Airport to AC power and to the Internet modem (or modem/router).  Open Airport Express on your Mac or other computer and accept all of the recommendations.  After confirming that it works, insert your desired administrative and WiFi passwords.

  • My airport Express is not recognizing Ethernet cables, therefore not allowing my cable modem to connect to it. This is resulting in no Internet connection. I upgraded the firmware to 7.5.2 and it attempts to connect but just keeps flashing. Any thoughts?

    I've tried other routers in place of the airport and they work fine, but I really want to use the airport instead due to the wireless speaker addition.

    I assumed that you have already tried using different "known good" Ethernet cables, just in case the one you have now is faulty ... correct?
    Assuming the answer is "yes," the other option would be to perform a complete power recycle of your networking gear. This is something that should be performed whenever making network equipment changes.
    Please try the following:
    I would recommend that you do the following as a minimum:
    Power-down the modem, AirPort base station, and computer(s).
    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.
    Power-up the modem; wait at least 10-15 minutes.
    Power-up the base station; wait at least 5-10 minutes.
    Power-up your computer(s).
    In this basic configuration, computers connected to the base station, either by wire or wireless (as appropriate for the base station type), 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.

  • Archlinux not cooperating with cable modem?

    I dual-boot Windows 7 Pro and Archlinux, both in 64-bit versions. For whatever reason, my Archlinux install does not cooperate very well with my cable internet connection.
    I have a basic 3/4 M connection through Time Warner, and the Motorola Surfboard SB5101 modem is connected to my laptop via an ethernet cable only. The odd thing is, I have been able to successfully connect to the Internet while in Arch, but I have only done so twice. Every other time, "netcfg ethernet" says DONE, but when I try to go online, do sudo pacman -Syu, ping www.google.com, etc., it becomes clear that I am not actually online at all. If I try to do a "dhcpcd eth0," the output--which I do not have, sorry--seems to suggest that I have connected, but I notice that the time to renew is very low, only about 3125 seconds, for example.
    I never had this problem while I was still at Georgia Tech and using their dorm internet. I could always connect via ethernet without a hitch, so it used to work. I have since graduated and have moved, thus requiring me to go with an ISP. I have no problems connecting while in Windows 7, and as mentioned, I have connected before while in Arch. It's just that I can't seem to connect on a regular basis, and I haven't had any success in the last few boot ups.

  • EA2700 not getting IP from modem

    Just received this new EA2700 router  the other day, have noticed this problem has been reported a few times in other forums.
    Went from a WRT54G connected to a DLINK 202 modem, actually they had no problem, I was just upgrading, when swapping out the router, I noticed it took a very long time with many reboots of modem and router to get an IP, which is set for DHCP from Comcast. The old combo would get an IP within a minute of a reboot.  So, just to complete my upgrade, I bought a Motorola 6141 modem, had it set with new MAC at Comcast, same problem with router trying to get an IP.  
    I did find if you reboot the modem by itself, last, while router is up, the router will get an IP within a few minutes. But, if they are both rebooted together or if the router is rebooted by itself, it will not grab an IP. I have not seen a solution for this "known" problem in all the forums I have read, I have seen quite a few people become very frustrated and just give up on their EA2700 or buy something else.....firmware is latest, I've tried MTU at 1365, IPV6 off/on, resetting, running install app, same problem. So unless someone has the real answer for this, I could be one of those swapping this for another model or brand, I'm afraid.

    Khan,
    The problem of users not getting IP from the DHCP usually happens when 'spanning-tree portfast' is not enabled on access ports. PCs don't wait long enough for DHCP responses and time out.
    Can you make sure all the access ports, to which the users are connected to, have spanning tree portfast enabled.
    HTH,
    Sundar

  • My Imac late 2012 running Yosemite does not recognise my Huawei 3g usb modem. itried to install Java bt still it does not although the same modem works with my MacBook pro . any help please

    My Imac late 2012 running Yosemite does not recognise my Huawei 3g usb modem. itried to install Java bt still it does not although the same modem works with my MacBook pro . any help please

    Hey there mbarikiwa,
    If your iMac still has not recognized the usb modem, I would use the troubleshooting for Yosemite USB issues in the following article:
    OS X Yosemite: If a USB device isn’t working
    If the device is connected to a USB hub: 
    Make sure the device and the hub are the same speed. Connect USB 3.0 SuperSpeed devices to a USB 3.0 SuperSpeed HUB, USB 2.0 Hi-Speed devices to a USB 2.0 Hi-Speed hub, and so on. 
    If the device doesn’t have a power cord and is plugged into another USB device that doesn’t have a power cord: 
    Try plugging the device directly into your computer’s USB port  or into a USB device that does have a power cord. You might need to disconnect and reconnect the other device as well, if it has stopped responding. 
    If you have many devices connected to your Mac: 
    Disconnect all USB devices except the device you’re testing, an Apple keyboard, and an Apple mouse. Make sure that the device is connected directly to the computer, and that any hubs or extension cables are disconnected. If you can use the device now, the problem may be with one of the other USB devices or hubs you had connected to your computer. Try reconnecting them, one by one, to your computer. When you find the device causing the problem, review its documentation for further troubleshooting steps. 
    Verify that the device appears in System Information: 
    Choose Apple menu > About This Mac. In the window that appears, click Overview, then click the System Report button to open System Information. 
    In the window that appears, see if the USB device is listed below Hardware in the Contents list. If the device appears but does not work, review the device’s documentation for further troubleshooting steps. 
    Restart apps: 
    Quit and restart any apps that use the device. 
    Restart your Mac: 
    Choose Apple menu > Restart.
    Check your device’s USB connection
    Thank you for using Apple Support Communities.
    All the very best,
    Sterling

  • Back to my mac and cable modem

    I can't find a definitive answer to this question. Is there a cable modem that is compatible with Comcast that supports Back to My Mac?
    Right now we have Comcast for business with fixed IPs, so I have just been using afp:// and vnc:// to access my home mac while on the road. But in the interest of saving $$$, I want to switch to Comcast for home, which doesn't offer fixed IPs.
    The last time I tried (with Mavericks), I could not connect to any computer at home through Back to my Mac because the Comcast-supplied modem didn't support Upnp (Universal Plug and Play). A brief search could not find any cable modems that do support Upnp. Am I missing something, or should I give up on the idea?

    Is there anyone out there who uses Back to My Mac (for sharing files and screens) and a cable modem? If so, how well does it work? Did you get a special modem or just the cheapest one that you could find?

  • WRT54GS with Mac OS 10.6.8 and RCN cable modem not working

    Hello,
    I have a Linksys WRT54GS, version 6 with Mac OS X (version 10.6.8) hooked up to a Scientific Atlantic cable modem, with RCN as the ISP.
    Recently, RCN had some network issues, and so I had to power down and reset my modem. The modem is working fine now -- no problems at all when the Mac is connected direclty to the modem.
    The router's network is OK in that I can connect the Mac wirelessly to the network, but I can't connect to the internet through the router (through neither the wireless or wired connection).
    I have downloaded the latest firmware update for the router, following the Linksys site instructions, but this has not helped me solve the problem.
    Does anyone have any advice as to what I should do? I did call Linksys tech support on the advice of RCN, and they said that the router does appear to be working (power, WLAN, and Internet lights are on), but they would be charging me nearly the cost of a new router to fix the problem.
    Any advice would be appreciated!

    Since you upgraded the Router WRT54GS with the latest firmware so once reset the Router and power cycle the whole network… Then connect the Modem with Linksys Router on the Internet Port and then connect any one computer to any one of the Ethernet port on the Router [Numbered – 1, 2, 3 and 4]… Let me know the RCN connection is a DSL connection or cable connection…
    So if you have a DSL connection you can refer to this link:
    http://www6.nohold.net/Cisco2/ukp.aspx?pid=93&login=1&vw=1&app=search&articleid=4020&userrole=Linksy...
    So if you have a Cable Internet Connection you can refer to this link:
    http://www6.nohold.net/Cisco2/ukp.aspx?pid=93&vw=1&articleid=3686
    As far as the wireless is concern:
    # Open up the browser and on the address bar type 192.168.1.1 that will open up the Router setup page…
    # Then Click on wireless Tab create the Wireless Network Name SSID and select the channel to 6, 9, and 11… Click Save Settings...
    # Then Click on Wireless Security sub tab and select the security mode and provide the password as per the requirement… Click Save Settings...
    After doing the settings try to connect the preferred network on the wireless devices and check the connectivity….

    You need to power off the modem for 15-30 seconds, then power back up and then connect. The modem is remembering the last connection (your friend).

  • My new HDD for Macbook pro 13" unibody is not recognized and I am using a new SATA cable

    Hey everyone,
    I have a particular problem that I cannot seem to find an answer to.  My new 500gb internal drive for my Macbook Pro 13" unibody is not recognized.  The old HDD broke on me so I bought a new one but my macbook pro would not recognize it.  To troubleshoot that issue I purchased the SATA cable and replaced the old with the new.  The new HDD still will not show up in disk utility. 
    Please let me know what you think I may have missed or should do.
    Thank you

    jc1388,
    Bring it to an Apple store Genius bar (make an appointment, so you don,t have to wait around forever) they will diagnose it for free and tell you your options/pricing. They have more extensive testing tools, maybe your logic board is failing/failed.
    best of luck
