Router is not connecting to the new cable modem

Time Warner has replaced my cable modem with a Motorola SBV1521 and my Linksys BEFSR81 router cannot connect to it.  No lights for the WAN port when the modem is connected. I have tried everything what Linksys said in their "set up a Linksys router with cable Internet Service" including the upgrade of the firmware and pwer cycling. (I can connect to the modem when it is plugged into a LAN port, but not when it is plugged into the WAN port as it should). Any ideas?

As a last resort, I swapped the two cables (one of the modem router and the other between the router and the main computer). It worked!

Do not know why. The two are category 5 cables and the original path was working with the previous modem.

I would be interested if anyone can explain this to me.

  • WRT54GL does not connect the new cable Modem

    Hello, I hope someone can help me. I just changed internet providers and my router does not work with the new modem they proived. I had been with ATT and has configured the modem/router ATT to act as a pass through my WRT54GL. Now, when I connect my new modem (which is also a wireless router) to the WRT54GL, I get no connection on the Linksys. However, if I plug in my modem att, resume service (I've not turned my old Internet again until I get this resolved). I tell myself that some setting prevents the WRT54GL to connect but not sure how to determine who it is: I'm not very well informed in this area and only followed a guide online when I configured the router to worek with ATT modem. I'm hoping to avoid resetting the WRT54GL to the deault factory because my old model Roku connects and I cannot change the network, it connects to due to losing the physical remote control. If anyone has any suggestions or can help me trouble shoot, I would really appreciate it!

    HI idkidd,

    You can disable the Wi - Fi modem to avoid any conflict on your Linksys router. And for the WRT54GL work with the new modem, you must reconfigure. The router might still be trying to remember the previous modem settings.

    Try these steps:

    * Connect the computer directly to the modem and check the IP address (Windows) (MAC OSX )

    Note the IP address

    * Now, unplug the modem from the computer

    * Connect the computer to the Ethernet/LAN router (leave the disconnected modem) ports

    * Determine the IP address of the computer, get the router. Then, compare it to the IP address, you have the modem

    * If you get the modem 192.168.1.x and is also the router 192.168.1.x, which means that there is a conflict of IP address

    You can use this link on how to set up the router again with the new set up a router with DSL Internet service Linksys modem

    I hope that these AIDS!

  • Router is not connecting to the modem so I can't get internet

    All right-_ - I tried a lot of things with this so I get irritated sorry. Here is my info I have a Linksys Wireless Router with SpeedBoost Firmware Version 7.2 WRT54GS (latest version). I'm trying to use it with a Sprint 645 series Modem. My IP address when you are connected to the router and the router connected to the Modem is 192.168.1.100 who my ISP said was ok to make it work. While it is just connected to my modem, it's the same thing except replace the 100 by 1. My ISP uses a measure of security where The Thing DHCP is 192.168.1.1 and so is the DNS server and default gateway and im not sure if this has something to do with it. I used the ping at a command prompt to make sure that I am connected to the router when its plugged up and it is. This is a new router. I have internet with Modem just perfectly. I tried to reset the router and that does not work-_-. I don't think it is important more because I tried to fix the many way people have told me and it didn't work, but I'll tell u in any case. When I put up the first router time I hung and lit everything at the beginning. Then I noticed that it says Run CD before to connect the cables... those who were not in the instructions but wtv... anyway resetting should have fixed or so I was told by other people on this forum. I use a laptop with Windows Vista, and I don't have access to a desktop computer in case I need a XD. I can connect to the router fine because I can access the Setup page... and I can connect wireless... The ONLY problem seems to be that the router will not connect to the Modem... for some reason of wtv-_ - I think that its because the entire security measure on the way to the DHCP and the DSN and the bridge are all 192.168.1.1, but that's just me. I'm sorry this is very long but I really want this problem-_ - I had this router for a month and becomes really annoying so please help . My ISP is Embarq. I ran the installation CD and I had all through the last step (standby router) after having connected the power supply to the wall for the router. Just, it is there forever and then says "error: 322 cannot find router or something like that." There are 3 steps to try to fix it. It says to make sure that the router is connected (it is), it is said also to make sure that u does not actually connect your old router, (I don't have a-_-) and then re-run Setup. and by the installer, I mean where u plug in all the cables in the right way. * sigh *.

    If you need anything else please ask.

    Your second post says "" ignore this "so I guess everyone thought that you set..."

    When you connect through your router that you have two instances of DHCP past... one is your DSL modem with router IP address on its WAN interface. The other is the router that gives your computer an IP address via the DHCP server on the router. The IP address of the modem gives your router is in the 192.168.1.0 network. Unfortunately, by default, the reange of Linksys routers LAN IP address is also in this range. For that to work, you must set your router 192.168.2.1 LAN ip, so that the LAN and WAN router interfaces are in different networks.

    To do this, unplug the DSL modem router, power it and your computer, and then connect the computer to the router by an ethernet cable. Turn on the router and the computer, and then go to 192.168.1.1. Change the LAN IP on router 192.168.2.1, save the configuration, and then restart the computer. Once the computer returns to the top, navigate to 192.168.2.1... you should be able to get to the router GUI configuration.

    Turn off the router and the DSL modem, connect the router to the modem via the Internet port using an ethernet cable, and then turn on the modem, then the router... you should be good to go...

  • WRT54G v.5 will remain not connected to the new laptop / Windows 7 Premium

    WRT54G v.5 will remain not connected to the new laptop / Windows 7 Premium. It works continuously with a cycle detection, connection, loss of connection; detection, connection, loss of connection, etc... The router works through this cycle, basically acting as if I disconnected and then reconnected to the power to reset, it disrupts my Internet connection to my Wired iMac and wireless, another office to the floor. Paid for Linksys support today and through remote access, he put up a new network on my desktop (iMac). After finishing, the problem still exists. When I told him that the problem had not been corrected, he said just wait an hour or two and it should work itself. She, of course, did not himself. Any ideas out there?

    Nevermind - I seem to have solved the problem with a simple firmware. Funny how the Linksys technician support don't think to ask what version of the router I have or suggest that I should try to upgrade firmware first. However, he is quite good at trying to upsell me for a new router instead of trying to help me solve the problem I had. It makes me want to go buy Netgear next time, thanks a lot!

  • Router is not connecting to the internet.

    I can connect to my router both wired and wireless, but the router is not the internet. I use a cable modem with Comcast as my ISP.  When I plug the cable modem directly into my PC (as I do to post this message) I access the internet without problem. When I plug the cable on my router, I can't connect to the internet.  With my Wired internet router and my PC wire3lessly connected to my router, here is the result of my diagnosis:

    Can you tell me what I've misconfigured?

    Thank you!

    Well problem solved! Poster on this forum, and after receiving no help, I went to my local Best Buy and asked them to recommend a router that wasn't a Linksys.  I came home, plugged in my new Netgear Wireless-N-300 router, ran the installer and poof!  -I'm on the internet.  Linksys thanks for forcing me to buy a better router.

  • HP printer will not connect with the new modem

    I just installed a new modem which has replaced a router and a modem.   But now my Printer (Deskjet j310a) HP does not work.  The window of the poster printer 'Wireless is not connected' shows you settings button choice: Disable wireless. WPS; Default values.  I don't know what to do and would like to return printer.  And before I changed modem, there was a small symbol of bluetooth on the bottom of the screen and it is gone now.  Any ideas?

    Thank you.  I'll try that and I'll let you know if it works for me.

  • Router is not connecting to the computer

    I just replaced a bad on my computer's ethernet jack.  Now when I plug the router in there I don't get everything internet.  The router has internet and my laptop wireless connects fine via the wireless signal...  I replaced the power cord from the router to the computer with a brand new, only one I know works.  Still no internet.  When I look at the network settings, the computer says that it is connected to the router.  But no internet signal.  I also plugged the network directly into the computer and it works fine.  The ethernet jack is working.  Any suggestions?  I don't have the book and cd for the router...

    Perform the following steps:

    # Open the browser and in the address bar type 192.168.1.1 which will open the router configuration page.

    # Bring back the MTU (Maximum Transmission Unit) of 1500 to 1400 or less (usually found on the main page / basic configuration of your router).

    # Click on wireless tab select width of the channel to 20 MHz only and channel 6, 9 and 11.

  • Application manager a few laps/does not - could not connect with the new installation

    Bought a perpetual license for Adobe Acrobat Professional DC and the installer downloaded from licensing.adobe.com

    No creative Cloud applications exist on Mac.

    Some versions of Adobe Reader or Acrobat Professional have never existed on this Macbook Air.

    10.10.5 running

    Installed without error.

    Launch Acrobat and Adobe Application Manager launches rather telling me that I have to sign.

    I click on the Connect button and a new "Adobe Acrobat" window appears with rotating boxes - that never cease.

    I have to force quit the Application Manager, because it becomes completely insensitive although Force Quit does not (do not) then for the name of the program.

    I uninstalled Acrobat and reinstalled but I got the same error.

    I have an internet connection then it should be able to reach the sign to the server.

    Checked the Console logs - is the thing in Adobe Acrobat Update Helper DC.log which shows that he met "errorCode 1001: received an exception when checking for product updates Acrobat update for assistance." Jump to the update of this product". Which occurred once. I force quit the Application Manager at least four times now. No crash log is written to the Console.

    Grateful for any suggestion.

    I have a problem with connecting to wifi networks. My laptop only connect to wifi networks that I have already connected to in the past but does not connect to all nine. The computer will recognize the but won't give me the possibility to type in any password. For example, I can connect correctly to the House and my moms place as wifi passwords are already saved on my computer.

  • SRP526W router is not connecting to the ADSL.

    Help please,

    I bought a Cisco Small business Pro SRP 526W modem/router for use in the United Kingdom on ADSL.

    Connection and set-up, the unit does not recognize all adsl service. I checked that the LAN interface is enabled.

    The ADSL status shows DSL and DSL Status Idle mode of modulation NO FORMS, and unlike any other ADSL device I used, does not retry the connection. All other routers ADSL modem connected to this work of line ok.

    I presume that the unit was defective, but thought I check the firmware version and update it because it is a model of new (ish).

    The device status screen is fixed and the firmware version 1.01.01 (006) January 22, 2010

    A newer version is available and I downloaded it. After combing through the extensive documentation, check the Cisco website and each screen of the device to the search I can't find how to upgrade the firmware.

    I know that this is aid refers to it.

    Can someone tell me;

    1. is this good normal UK ADSL device.

    2. where is the option to upgrade the firmware.

    3. in the event that I RMA because it clearly is in brick.

    4 why Cisco would put their name to such a poorly documented system

    Any response would be appreciated.

    Hello

    SRP526 takes support ADSL2 + on carriers of ISDN.  In the United Kingdom, ISDN on POTS lines (telephone analog) is used exclusively.  To do this, need you the SRP527W.

    Documentation for the SRP500 is published on Cisco.com at http://www.cisco.com/en/US/products/ps10500/tsd_products_support_series_home.html.  The Administrator's Guide should provide you with the information you need.

    For your information, upgrade code on this unit, you must log in as "admin" default password "admin" (like you), rather than using the "cisco" basic user login, then select Administration > Firmware Upgrade.

    Hope this helps,

    Andy

  • LR 4 files are not connected in the new library facility

    Have just downloaded LR4 on C drive on windows 7 Home Edition premium, all photos and files are there but, library folders are displayed as by's car that was on a computer, I recently replaced, so when I put them in develop it said "missing folder path does not exist" the images are on the external F drive " , any ideas on how I can remedy this. Also I thought that LR4 would merge with existing LR2 so now I have two programs of LR on my C drive, it's how it should be?

    Right-click on the missing files to the library and select "Search for the folder missing" to move the folders.

  • Linksys Router WRT160N - Wireless does not connect to the cable modem

    I installed the Linksys WRT160n router to replace an existing G router. When installed the new wireless router works, but the router does not receive a connection (IP address - look under status) of the cable modem (so no internet). When I reconnect the old router and then connect the new router, I get any internet connection through two routers (so the old dishes router the IP address that accepts the new router).

    I have configured the router N new for

    "Automatic configuration - DHCP", no need for connection, IP address dynamic, etc (as required by ISP - Timewarner)

    I tried to renewal and release IP address by the router N when it is connected directly to the main switch (the switch to connect to the cable modem). In so doing, shouldn't that assign a new IP address to the router?

    I am allowed 3 IPs from the cable company (because of the switch) and I use all three with three different internet IP cameras to each address for home security system.

    Any suggestions on why the router is not connecting to the internet? Do I need to reboot physically everything on the network, including the cable modem?

    If I understand your post, you said that your ISP gives you 3 Internet IP addresses and you have 3 cameras that use one of these Internet IP addresses.  If this is correct, then that leaves no IP Internet address for your WRT160N use - so that would explain why your WRT160N cannot get an Internet connection.

    If I misread your post, and you have an Internet IP address available for the WRT160N, you might have a problem with your modem and two WRT160N tries to use the same 192.168.1.x subnet.  To check this, follow these steps:

    (1) Please indicate addresses that use your cameras (IE before you take the test below).  If the addresses do not begin with 192.168, then erase the last half of each address.

    (2) Please indicate your ISP

    (3) Please indicate the make and exact model of your modem (not the WRT160N) number.

    (4) Please do the following test:

    Put your entire network.  Disconnect the switch (including cameras) to the modem.  Using an ethernet cable, connect your modem directly to your computer.  (Do not use the WRT160N for this test).  Turn on the modem and the computer.  Make sure you have an active Internet connection, then go ahead with what follows: (even if your Internet connection does not work, include this and move forward.)

    Go to 'Start' > all programs > Accessories > command prompt.
    A black DOS window will appear. Type "ipconfig/all" (with no quotes), and press the Enter key.   Copy all results in your next post.  To make the copy, highlight the results, and then use the keys copy (Ctrl-c) and paste (Ctrl-v) keys.  If your "IP address" does not begin with 192.168, then for security reasons, delete the latter half of your IP address.

  • I just installed a new router and now my desktop running Windows XP computer does not connect to the internet.

    Hello

    I just installed a new router and now my desktop running xp computer does not connect to the internet. I know that it is not the router because I plugged the cable into my laptop running 7 and it works fine. When I try to dhcp I get 169..., when I put manually the IP just get no access to the internet and can not ping to the router address. I tried to run the net work Assistant, emptied my dns, disabled all firewals, still nothing.
    Any suggestions?
    original title: connectivity Limeted

    The zero configuration utility works very well. But it is a desktop computer and on cable. All other wired and wireless PC in the office is working well, then it's definitely this PC. He came out of nowhere, I install a network printer on the PC but that's all.

    Your messages are a bit terse, but if I understand correctly

    • You have a router connected to the Internet and multiple computers connected to the router, some Ethernet cable and others by wireless.
    • All but one of these computers can reach successfully from the Internet via the router.
    • A computer that can't browse the Internet is connected to the router via an Ethernet cable.
    • You disconnected the cable between the router and the desktop problem and connected it to a Windows 7 laptop and the laptop connected to the Internet via the router.
    • You haven't seen any error message (except, perhaps, a message on "Limited or no connectivity").
    • You have installed Windows XP Service Pack 3 (or at least Service Pack 2)

    Assuming that all the foregoing is an accurate summary of the situation, I suggest that you do the following:

    Open a command prompt window (start > run > cmd > OK)
    Type the following lines and press ENTER after each line

    Netsh reset winsock catalog
    netsh int ip reset c:\resetlog.txt

    Close the command prompt window and restart the computer.
