WRT54G router with cable internet problems

I have a WRT54G wireless router and comcast internet.  The internet works as long as the modem is plugged directly into the computer, but whenever I connect everything through the router I lose the internet.  I'm pretty sure that the router isn't broken or anything because up until a few days ago it was working fine with verizon DSL.  I didn't encounter any problems until the cable modem.  I've tried as many solutions as I could find within the support area and nothing seems to work.  Please help!  Thanks in advance.

Try this connection first:
Connect Modem to the back of router using Ethernet cable at the internet port of router.
Connect another cable from either 1-4 ports from back of router to back of your computer.
Open routers set up page using http://192.168.1.1 …you will see username & password …leave username blank & in password use admin.
Under set up look for “mac address clone” sub tab …. Enable it & click “clone my pcs mac”…click save settings.
Do power cycle & check whether it’s working or not.

  • Having trouble setting up a linksys WRT54GS router with v...

    Having trouble setting up a linksys WRT54GS router with verizon DSL using a westell 6100F modem. the modem works fine by its self  but the router will not connect  to the internet when installed like the cd tells you to.
    online help and phone help has been less than helpful,  anyone have any Ideas?

    Ok I found " Installing the liksys wireless router with a westell 6100 modem" in the verizon troubleshooting guides. printed the instructions so I would'nt forget. step 1 open your web browser and enter http://192.168.1.1 in the address field.  PROBLEM it comes up with a login screen that I don't know how to sign into. tried the obvious stuff. cannot get past the login screen. I knew this sounded to easy to be true. anyone have any ideas? 

  • Setup 1941 router with cable modem and 2 vlan?

    hello everyone,
    i need a little help setting up my new 1941 router with cable modem using 2 vlns.
    this is what i have:
    1- 1941 router configured as g0/0 wan port facing isp configured as (dhcp). g0/1 is lan facing the switch (192.168.1.1)
    dhcp pool (192.168.1.x)
    2- sg300-28pp switch.
    3- wap371 AP/ 11pcs..
    now everything is working perfect except sometimes we have more than 250 to 300 people trying to connect to the wifi, the router will have no enough ip addresses.
    i heard that i can setup 2 vlans to solve this problem? and is there any setup that i have to do on switch and Access points? 
    please i will appreciate any little help 
    Regards 

    hello Andre Neethling  i added network 192.168.0.0 255.255.254.0 to dhcp pool config and it seems that it is working but i am concern that i am going to have problem in the future so please take a look at the running config and let me know if i have everything done right. also we want to order static ip address from the provider for our security camera system and we will not longer receive dhcp ip from them and my router setup is to receive it as dhcp on g0/0 so what i should do about changing the settings on g0/0?
    i appreciate your help

  • WRT54G not working with cable internet access - request for help

    Good evening!
    At least that's the time when I write this.
    I have a PC running Vista 64-bit version. 
    Until yesterday, I was connected to the internet using my WRT54G and a cable modem. There was a power outage (or blackout) and I lost my internet connection. I was not home when this happened. I got home and found the circuit breaker off. Since then, I can not access the internet anymore when I use the router. 
    If I connect the computer to the cable model directly, I can access the internet without a problem (hence I'm able to post this). 
    If I connect the computer to port 1 in the router, and connect the cable modem to the internet port in the router, I am not able to connect to the internet. 
    I have already:
     - updated the firmware to the latest version (it was already installed)
     - reset the router pressing the "reset" button for 30 seconds, unplugging it, and reconnecting power still pressing the "reset" button for 30 seconds. 
     - power cycled the devices
     - tested 3 differnet patch cables that I know are good and they work
     - reset the modem via a soft-reset remote request sent from the cable operator
    None of these options have helped me restore my router's connection to the internet.
    I know the router is working because I can print using my wireless printer and I can see my shared drives in the other PC I have connected to it,  but none of them are able to connect to the internet!
    Does anyone have any additional ideas on how I can fix this, before I go out and buy a new router?
    Thanks in advance!
    Pablo

    As you have mentioned in your previous post, that you have resetted your router and you are still able to Print from your Wireless Printer, I Feel that your Router is not getting Resetted properly, whenever you reset your router your router goes to Factory default mode, and it will change the wireless network name to "linksys" and your Network will be unsecured. Press and hold the reset button for 60 seconds...Release the reset button...Unplug the power cable from your router, wait for 60 seconds and re-connect the power cable.
    Once you reconnect the power to the Linksys router, On your computer Open IE and in the address bar type (http://192.168.1.1) and hit enter, when prompted for username and password, Leave the username blank and in password type "admin" and click Ok. Below the Setup tab you will find MTU, So change it to "Manual" and change the size from 1500 to 1365 and Click on Save Settings. Then Below the Setup Tab you will find the Sub tab "MAC address Clone" click on it and "Enable" and click on "Clone your PC's MAC" and click on Save Settings. Now you can Unplug the Power from Router and Unplug the Power for Modem. Wait for 30 seconds, and 1st connect the Power to your Modem and wait till all the lights goes Stable then you can connect the power to Linksys router and once all the lights are sold. On your computer Open IE and check if you are Online.

  • How do I set up WRT54G router with 4 computers and WVC54GC Wireless Camera

    Can anyone please tell me how to set up my Home Network with full security turned on?
    I have at least 4 neighbors that show up on my wireless connections list. I have a daughter that loves music and is constantly downloading viruses but only on one wireless connection. The rest of us want to be protected from that computer. My system consists of the following:
    One Linksys WRT54G Router
    Two Linksys WMP54G Wireless PCI adapters,
    Two Linksys WVC54GC Wireless Cameras  (Possibility four if the 1st two ever work OK.)
    Two Linksys LNE100TX PCI Ethernet Cards,
    One HP Ethernet Printer
    Three computers were connected by Ethernet cable and one was wireless. I did not change the admin password and I thought everything was working fine for a couple of years until I found that the wireless computer was acting as a “drone” and slowing everything down to a snails pace.  It could even turn itself on.
    I changed one of the Ethernet computers to wireless and decided that it might be time to also change the password and increase security.  Setting up security completely shutdown the wireless drone computer. I was OK with that, at least until I can reformat that harddrive.
    I then decided while I was at it, I would add a wireless camera (WVC54GC). I set it up using the software and Ethernet cable that came with it. After 6 tries I finally got the camera to work with the cable attached, but it does not work wireless and now none of the other computers connect any more. Is there a limit on how many connections? Should I reset the router and if so, do I disconnect the DSL modem? I’m afraid of the “drone” computer because I found some very bad malware on it. One in particular caused me to replace a hard drive.
    I’ve read page after page of network stuff on the Internet and I guess I just don’t know how to ask the right questions. I’m tired of fooling with this.

    hi , when u talk about security , are u referring to the "viruses" your daughters PC may be propogating to the rest of the network , or are u referring to external attacks on the router or your wireless PC"s ???
    In case u are referring to the "virus" attacks , the best you can do is install a good antivirus software on all PC"s and keep the virus definations updated....
    In case u are referring to the wireless security , i'd suggest that your use WPA2 personal. you can select WPA2 by going to the "wireless security" option.
    let me know if u need anything more.

  • Not able to connect my Iphone to my WRT54GS router with security enabled

    As the subject line states, I'm not able to connect my Iphone to my WRT54GS router when the security is enabled. When ever I attempt to connect to my network with my phone it always tells me the password is incorrect. I have double checked the password in the easylink advisor and it matches up. I have also tried both WPA and WEP with the same result, I know that the wireless is working on the router as I turned the security off and was able to connect to it. I updated the firmware this evening also with no changes. If anyone could help me with this issue it would be much appreciated.

    First of all, in the router, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also, in the router, set "SSID Broadcast" to "enabled". This will help your iPhone find and lock on to your router's signal.
    To connect using WEP, enter WEP "key 1"  (found in the router)  into the iPhone, not the WEP password or passphrase.
    To connect using WPA, make sure that there is not an encryption nomenclature problem.  For example, WPA is not the same as WPA with AES.  Please note the following:
    WPA    =   PSK    =   WPA with TKIP  =  WPA   personal
    WPA2  =   PSK2  =   WPA with AES   =  WPA2 personal
    I am not certain, but your iPhone probably does just ordinary WPA  (not WPA with AES).  Assuming that this is correct, then the router should be set to:
    "WPA personal"  with  "TKIP"
    Also, in the iPhone, be sure to delete the entry for your unsecured connection to your router, before you try to input info regarding the secured connection to the router.
    Hope this helps.

  • WRT54G router Ver 6 internet drop

    This one connect to a DSL modem from comcast was working fine after a few days the connection is gone. Cannot go on the internet, when I click on router status everything is on zero (IP, subnet mask, and Gateway). However when I just installed it, it pick up everything (IP, subnet, and Gateway) I set it up on  automatic configuration (DHCP) I gave a name to the router, I put it on channel 6, and I click save. Then for security I choose WEP, and I click save. So, could you please help me find the reason why everything is on zero. I did reset it, it still doing the same thing. Open my laptop it sees the router, but no internet. Router lights are blinking like there is some activity however nothing. Any help please   
    Best regards,
    dody127     

    Who is your ISP...DSL or Cable...?
    Have you checked the connection from the Modem when you loose the internet from the router...?

  • Trouble connecting Cisco router with cable modem for Internet purposes

    So I am requesting help from the Cisco community on this issue as the cable company states there equipment is working fine.  At all my facilities I have a guest Internet service setup through a local Internet provide to provide Internet services to the residents and guests.  I have the cable modem usually a Motorola SBG6580 or a SMC 8014 (both provided by cable company) connected to my router on a FE or GE interface.  I am using static IPs and using the cable modem just as a modem (bridge mode).  Over the past several months these connections have just stopped working.  I have not made any drastic changes to my router configs; however, the cable company has updated the firmware on these modems.  I am wondering if that could affected how the modem and router talk.  I was told by the cable company that the modem sees the Cisco router but that the port is inactive.  My router shows the port is active and traffic passing.  Does anyone have any ideas that could point where the problem lies?  I will post a basic config to one that currently does not work.  I am using a VRF to route a certain group out, using NAT.  Please let me know if I need to post additional info.  Any help would be greatly appreciated.

  • Problems setting up a WRT54G router with Vista

    My husband upgraded to Windows Vista Home Basic over the weekend (we don't have the newest version! omg!angst!woe!). Today, I got a call that our DSL was turned on, I set up the modem, got the internet working, and attempted to set up the wireless router.
    I have used the setup cd, the EasyLink program, and the directions to manually set up the router. I can get the router linked up properly, I can even log into the DSL modem through the router. The problem is that I can't get any of these setup programs to recognize the router. Even putting in http://192.168.1.1 brings up a "page cannot be loaded" error in both Firefox 2.0 and IE (however, when I remove the router, I can see the DSL modem fine with it). Is there some other way to get the wireless router set up, or do I need to wait for one of the two computers with XP to arrive (yay for moving with the military) to set up the router?

    Hi,
    I too am having problems connecting the WRT54GS to my vista enabled pc. I have installed the software but since connecting everything my internet access is now diabolically slow. This is on the main wired machine, not wirelessly. The router is obvioulsy doing something inbetween (possibly the firewall) but this has made the speeds almost unbearable, negating the object of the new pc !!
    Is there some settings I should eb checking ?
    Many Thanks

  • Using Catalyst 3550 Switch with Linksys Home Router and Cable Internet

    I've about pulled what little hair I have out of my head on this one, and need some configuration help.
    I have a Cisco Catalyst 3550 switch with five Windows 7 desktops, an Avaya PBX and five Avaya IP phones attached.  All of these devices are on a 192.168.0.0/24 subnet, and are communicating properly.  I will refer to this as network # 1. I also have SEPARATE network, we'll call network # 2, using AT&T ADSL service and a Netgear 4-port/wireless router/ADSL modem combo device, which is functioning properly with a couple of other Windows 7 desktops over its own wired Ethernet network, using DHCP, and also on a 192.168.0.0/24 subnet.  I thought it would be a simple integration, just plugging one of the 3550's ports to one of the DSL router's ports, in order to give the five Windows 7 desktop computers on network # 1 internet access via the DSL modem. Guess I was wrong.  When I connect the two switches together, although I get a good connectivity (green lights on both ports) and am able to ping the DSL router's gateway address (192.168.0.252) from network # 1's computers, the computers on network # 1 cannot access the internet. Also, the working computers on network # 2 lose their internet access as long as the two switches are connected together. I am not a Cisco guru, but there's got to be a way to make this scenario work.  Can someone provide me with a 3550 configuration that will allow me to extend my internet service from network # 2 on the DSL router to my 3550 switch and their computers?  Here's what I am looking for:
    INTERNET ---> ADSL MODEM ---> NETGEAR ROUTER ---> CISCO 3550 SWITCH ---> NETWORK DEVICES WITH INTERNET ACCESS

    The Netgear router is probably what's doing the natting. Is the 3550 configured for routing or is it straight L2? If you have the 3550 configured as L3, then it's going to be easy to do what you want. Just add a static route on the Netgear to point the subnet that it doesn't know about to the 3550. For example, if the Netgear is addressed at 192.168.1.1 and the Cisco 3550 is addressed at 192.168.1.2, but it also knows about the 192.168.0.0/24 (separate vlan), then you would put a static route on your Netgear for 192.168.0.0/24 to go to 192.168.1.2.
    The way that I would do it is to create a separate vlan on the 3550 and assign an address to it. Once you do that, make the port that the other switch connects to an access port of that vlan. (It would need to be on the same subnet as the existing equipment.) All of your devices would use it as a default gateway and then you would do the rest as above. You could also use RIP between the Netgear and Cisco if you can't do static routing.
    HTH,

  • UK User with Cable Modem Problem

    Hi all
    I have just signed up with VirginMedia for TV and Broadband. Access to the internet is offered rebranded Ambit U10C018 Data Cable Modem. I have a Mac BookPro 2.33GHz and a Airport Extreme 802.11n base station (firmware v7.2.1) providing my wireless network.
    Wired access to the internet (i.e. connecting my MBP to the cable modem via an ethernet cable) is fine.
    The problem I have is when I surf the web wirelessly. Requested web pages are taking a long time (15-30 seconds to load); pages which load instantly via a wired connection. I have used the AirPort Utility to try various different settings but they have not made any difference. The VirginMedia engineer who came to my house has suggested that there is an incompatibility between the AEBS and the cable modem.
    The Ping and Traceroute output below look normal. NsLookup returns quickly, so I don't think there is a DNS problem.
    My question is whether anyone else has had any similar experiences? What advice can you give me here? Should I look at getting another wireless base station?
    many thanks
    Nigel

    I wonder if my problem was solved which seems similar to yours. I have just brought a preused G3 , 400, running Panther. I want to use this as an backup to my DLS G4. It all seems oka and does everything it should do, but it seems unable to make a connection with any ISP. You can hear the modem dial out, but it fails to trigger a response from any ISP and the ISP numbers have been checked and rechecked, and I have checked permissions and done an erase and reinstall
    I have a feeling that this computer came from off a LAN and the modem has been in some way inhibited to prevent staff accessing the WWW. Has anybody come across this and is there anything I can do to get internet access.
    Any help much appreciated

  • How do you set up TC with cable internet?

    I know this may sound ******** but if I have a coaxial cable coming out of my wall and the is no coaxial cable input on the TC, how do you set it up without using the crappy router I got from TW cable?  Is there a coaxial cable to ethernet adapter?

    but if I have a coaxial cable coming out of my wall and the is no coaxial cable input on the TC, how do you set it up without using the crappy router I got from TW cable?
    Suggest that you ask TW to provide you with a simple modem.....not a router. The TC is also a router. You don't need two routers and it just makes things more complicated.
    Is there a coaxial cable to ethernet adapter?
    No. You need to connect the coax cable to a modem. The modem provides an Ethernet signal to the TC.

  • Wrt54g wired to desktop, internet problem

    i have the said router, my laptops work fine, one laptop has a wi fi and the second one has a linksys wirless usb, althouth i attach a SMC one also to a third laptop. all laptops work good. but the desktop is the problem, the desktop is connected to the router via a lan cable, for half an hour the connections works ok, but then the desktop loses connection from the router and then i have to restart only to make it work again. help!!

    Try few settings on the router setup page...
    Under setup tab....look for MTU size ....it is under "Auto" ....change it to manual & change the size from 1500 to 1300..... click save settings ....
    Click security tab ....uncheck "Block WAN request" & save settings .....
    Also check the firmware version on status tab of router ....

  • What is best modem for time capsule with cable internet?

    We're subscribing to Comcast

    Welcome to the Apple Support Communities
    Any modem will work. Note that you will only use your modem to connect your Time Capsule to it using an Ethernet cable, and it will bring the Internet connection to the Time Capsule, so all modems do the same
