Linksys Wireless Routers and RoadRunner Internet ISP

I have been using a Linksys wireless router for over 2 years now without any problem and then last night I lost total connectivity.
via the Router, I can connect to the modem directly (HardWire) and I am able to get to the internet, but if I try to connect the Wireless router to the Modem and wither wireless or hardwired to the router I can't get any connectivity.
I am at a loss, I even went out and purchased a new Linksys router thinking that the old one went bad.
I get the run around from ISP they said that it's a 3rd party router so they can't tell me anything.  And suggest that I just leave the router out.
I am at the end of my rope, any suggestions that would assist.
I am not able to ping anything through the router on the PC, but I can pink from the router to the internet.  using the diagnosis option on the router.  When I try to fix connection using Windows Vista I get a message that says it can't connect to the DNS Server.
Thank you for your Help

  • Problems with my LinkSys wireless routers since getting AT&T u-verse

    I recently installed AT&T u-verse. Every since it's hit or miss on whether I can connect to my two linksys wireless routers. Sometimes it connects fine but other times I can try for hours and never obtain an IP address. I never have a problem connecting to the 2wire wireless router which was installed when u-verse was installed but it doesn't have coverage for my whole house.
    The AT@T tech says the 2Wire has problems with routers being configured behind their router??? He said that I need to set my Linksys wireless routers up as access points???
    Anyone have any suggestions on what to try? Anyone else have issues like this after u-verse was installed?
    Thanks

    I've had AT&T U-verse since March, and I wish it wasn't the best option in my area. I have been through 3 of those 2-Wire Gateways and as best I can track down it's that DHCP Server. I have a BEFSR41v3 (and yes, I am NOT using the WAN port, just the switch at IP 192.168.1.10) and a WAP54G (IP 192.168.1.11) using WPA2-PSK and have been using for years now. AT&T tried telling me it was my wireless devices, which strangely enough worked PERFECTLY fine on my Linksys hardware with the same SSID/Key when I was with TWC. My wireless devices would work fine for a while, then gradually start having problems until by 2 weeks they are completely unable to negotiate an IP from the DHCP. Called AT&T, they reset the gateway, and everything works for 2 more weeks. Most my computers (wired or WiFi) are manually IP configured. Only my laptop (also used on a college WiFi) and visitors use the DHCP server (and the AT&T Boxes).  THUS far I've been reasonably successful by limiting the AT&T Gateway to 3 addresses for my Boxes, letting it issue them to the TV's, then adding my linksys router (ignoring the WAN port and using DHCP on with an allocation of 15 addresses) and setting the Linksys WAP to the #4 port. This weird setup now gets short lasting fits in the form of "Limited Connectivity" for my WiFi devices using Dyamic IP.  It can still access the LAN perfect, only that device has no Internet Access, and Windows says i'm being blocked by a Firewall. It self resolves in a few minutes without me doing anything and it MIGHT come once or so a month, or until they run another update which seems to ALWAYS reset that gateway (I've given up changing the password and now keep a txt on every system since it seems to reset at least monthly). A few days ago it's started giving me IP conflicts that disappeared within 1-2 minutes, which is odd since it is my manual IP's getting the conflicts... It did that for 2 days then hasn't since.
    Currently I'm wired as...
    AT&T Gateway 192.1681.254 w/ 3 DHCP range 1.160-163, WiFi disabled, and 3 LAN ports to 2 TV's and my BEFSR41
    BEFSR41 192.168.1.10 w/ 15 DHCP range 1.60-74, WAN port unused, 4 LAN ports to 1 Desktop, 2 unmanaged Netgear 1000 switches, and 1 to the WAP
    WAP54G 192.168.1.11 with it's gateway set to 192.168.1.10 
    1 Netgear switch provides wired access for the entertainment center (PS3, DVD player, DVR, etc) and open ports for visitors
    Other Netgear switch is upstairs and runs to 2 additional desktops and one more cable box...
    All my wired NICs are set to a 1.2x address and all configured WiFi devices (Wii and a pair of Android phones) i have on a 1.3x.
    Manual IP with a 255.255.255.0 mask and gateway 192.168.1.254, manually entering the DNS from the gateway's Broadband Details page 
    As far as I've been able to test and observe, that gateway is tempermental (and intermittent so tech support can't EVER find a problem conveniently) with anything using the DHCP other than the cable boxes. My manual set devices have had no problems other than that strange IP conflict that popped up on 3 computers, bugged me 2 days, then just never came back (also ironically the monday i was going to call a tech support about it)
    I've attempted to disable the DHCP entirely from the gateway and only use my Linksys DHCP. That seemed to work for a few hours untill, i'm guessing, the leases expired. Then all 3 TV's stopped. Everything getting it's IP manually or from the Linksys continued just fine, internet and all. The cable boxes only returned when i re-activated the 2-Wire's DHCP Server.
    I would like to try using the Linksys router to isolate my LAN (and everything else i can) from that 2-Wire with a cascade, just link across on a single static IP to dodge that DHCP, but i havn't been able to get the cablebox upstairs to work off the Linksys DHCP. Even then, I'm not sure how i can get a network split to work. If i only isolated the DHCP over my WiFi, they would still at least loose file-sharing with the my File/Media/Backup PC downstairs. Move that to the other side, then the PC's upstairs loose access. As is it's MOSTLY stable though, i just have to pull apart the gateway and cut down it's DHCP range so my devices will actually get an IP from my linksys. If i don't take away the 2-wires, i still get a high IP fail rate. It would be great if i'm overlooking some way to force all DHCP IP requests -OTHER- than the cable boxes to get their IP from the Linksys and not the 2-Wire
    Far as jdaley, I havn't tried to set a cascade since I'm having problems figuring out a means to isolate the boxes (and 2-wire) away from the LAN since one box is upstairs sharing a single cable with the computers there. Someone else seemed to report a success that way. If not that, then only other thing I can think of might be to just manually set all your WiFi IP addresses by hand
    Thanks for any other ideas on dodging this 2-Wire's DHCP I'd really appreciate it. I'm really hoping i'm just overlooking something SIMPLE.

  • Will Linksys wireless routers be updated to the final 802.11n spec when its finished?

    Will Linksys wireless routers be updated to the final 802.11n spec when its finished? I read that most can be updated to the final spec with a firmware update.

    I can't see why they wouldn't be. There'd be a whole lot of people upset if they didn't...

  • Can I use the Airport Express to connect to a Linksys Wireless Network and then use the Ethernet port on the Airport for a wired connection to a device for internet access?  Would I be able to then also use that Ethernet pt to a Ntwk Hub for more wired c

    Thanks for the help.  Looked but not clear on what I am trying to do as being possible.  Can I use an Airport Express to connect wireless to a Linksys Wireless Router, such that I can then use the Ethernet ports on the Airport to either connected to a PC wired, or even use a hub off the Airport Express to allow multiple wired connections to it? 
    I am not looking to have the Airport Express extend my wireless network, just connect to it and provide me wired connections in a different location from where my Linksys Route is located.  Would prefer to replace Linksys with all Apple, but just not possible financially yet.  Thanks for the help.

    If the AirPort Express Base Station (AX) is an 802.11n model, then yes, you can reconfigure it as a wireless Ethernet bridge. In this configuration, the AX would join the wireless network provided by the Linksys router and its Ethernet port would be enabled for either a single wired device or for an Ethernet hub or switch for multiple devices.

  • I need help setting this up. 2 wireless routers off one internet connection

    I have a cable internet connection.  I want to connect a netgear wireless router and then plug in a 80ft ethernet cable attached to a Linksys wireless router.  Can the Linksys router be used as an access point?  Or basically I want to use both wireless routers.  I need help putting this together.

    Yes you can do that, here are the steps on hot to do it.The router A or your netgear must be configured like router A on the illustration on this link ^_^

  • How can I use a wireless printer and the internet at the same time?

    Hi there, I just installed a wireless printer but to use it I have to click on the Airport icon and select the printer in the 'devices' list. This deselects my connection to my wireless modem. Is there any way I can print and look at the internet at the same time? This does not seem right to me, I print a lot of info from the net and don't want to spend time selecting and waiting for connection back and forth all the time.
    Bo

    I have a Linksys WAG54G2 wireless G router. This router has a Wireless Protected Setup button which I understood would initiate a search for wireless devices and aid setup but it seems to do nothing. I made the mistake of tryig to use the linksys installation disk to access a setup wizard and that just reset my entire network back to factory settings and it took me 4 hours to reconfig my system. Won't be touching that again. It all seems odd, the printer is compatible with the router as far as I can see but I don't know how to get the router to recognise the printer.

  • Connecting a cable modem, a linksys wireless router and my MacBook?????

    So... My cable modem and MacBook work great when connected with an ethernet cable. How the heck do I hook up and configure my Linksys wireless router with my macbook and the cable modem? This seems like a simple setup, but when I hook it up it doesn't connect me to the internet.
    Any help would be awesome!!!!

    Darren,
    The best advice I can give is to suggest you post in the right discussion group. This is the group for Apple Pages. You want the MacBook group.

  • One Printer - two wireless routers, and one Airport Express

    Hi all,
    I'll do my best to describe this convoluted situation in detail, please feel free to ask questions—I need all the help I can get.
    I am in an office with 5 Macs (some with wireless capabilities: my Intel iMac, a Mac mini, an eMac with a wireless card, and a new iMac running OSx 10.5) and one eMac with no wireless capabilities.
    We're all connected to an Actiontec router. The one eMac is hard-wired via ethernet to the router and the rest of us receive the signal wirelessly through an 2' thick concrete wall that makes for a slow connection. Our printer, an OKIdata C3200N, is also hard-wired via Ethernet to the router, which allows us wireless Macs to print on a crappy, slow connection.
    I got fed up with the slowness and brought in an Airport Express, which is now also hard-wired to the ethernet port and seamlessly and easily connects all the wireless-capable Macs to the internet. It's a joy. However, whenever we wanted to print, we had to switch to the slower Actiontec network b/c the printer was not connected to the Aiport Express.
    I figured I could remedy this by plugging a USB printer cable from the printer to the AX and all the wireless Macs would automatically find the printer through Bonjour. It seemed like a good plan; though I was worried that the printer would be confused by having both the Ethernet connection AND the AX connection (this could be the case).
    Now, I have been able to be on the AX network, find the printer via Bonjour (with Printer Sharing turned on). However, when I print to it (or any of the other Macs in the office try to print to it) a variety of errors happens:
    ...the printer jobs are paused and will not resume (this happens on the iMac running OSX 10.5)
    ...the print queue spools and says "waiting to complete job"
    Do I need to configure something through the Airport Admin Utility? Is this a lost cause because the printer is connected two ways to our computers? Is there any hope for printing on the AX connection?
    Thanks in advance for your input.

    Thank you so much Duane. Can you clarify what you mean by:
    I would recommend returning the printer connection to the original configuration.
    Thanks! I'll look up the other stuff about AX as a bridge (now to remember that AX admin password....)
    Thanks!

  • Wireless routers and Lifedrive

    Is there anywhere that I can check which wireless routers work best with the Lifedrive or are compatible?
    Sincereley,
    Post relates to: LifeDrive

    Mary, it all depends on where you will be using the service the most.  Wifi is a one-time cost.  Buy the router, and you're done!  You now can gain net access from anywhere in your home.  (Of course, there will be a slight learning curve involved with the router - you become your own "Network Administrator"! 
    If there is no Wifi access at work/school/nearby, then others feel the extra fees are reasonable for "anywhere" net/email access.  Just depends on your needs.
    As you may have discovered, these fees can range from $10/month for limited downloads to $40+/month for "unlimited*" access.

  • Linksys Wireless Router Slowing Down Internet

    Hi, I currently have Optimum Online boost through cablevision. I noticed I wasn't getting speeds anywhere near what Optimum stated my plan includes so I called them up. After troubleshooting they asked me to connect the cable modem directly into my laptop(bypassing the router) and run a speed test and then do the same speed test when accessing internet over the wireless router. The results of this showed that the wireless router was significantly slowing down my internet connection. I currently have a Linksys WRT54G V6 with firmware: v1.00.7, Feb. 16, 2006. Anyone have any ideas what in the router is slowing me down. FYI I am very close to the wireless router(excellent connection) with no interference around(my laptop and a dekstop are the only thing connected to the router) and I have tested this on multiple laptops wirelessly and it all shows that something in the router is slowing this down. MAC Filtering is disabled and the encryption is WPA - Personal AES-CCMP. Thanks! Hope someone can help. ppc

  • Conflict with 2 Linksys Wireless Routers in the same building

    At our business, we have a wireless router in our main office section and down the hall a ways we have one in a boardroom where groups come to meet. We have always had an issue with the 2 conflicting. If we get the one in the boardroom connected, our wireless router in the main office goes down. We currently have a group in the boardroom right now and they wanted internet access - so I set up the router, however now it says the router is connected and the network has been found, but no one can access the internet or email. I've even taken a laptop back there and have the same problems. I've called our wireless cable company, but they said it's an issue with the routers/network. I'm not the IT person - he's on vacation so I'm looking for ideas on what to try. Anyone know why our routers would conflict like this and now why the one in the boardroom will not actually allow anyone to access the internet? I don't know if there is a network issue rather than a router issue or what. Just not sure what to do at this point.

    On that same note make sure no one is using a 2.4 Ghz Cordless Phone near either of the routers as this will also interfere with the routers signal being broadcast.

  • 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.

  • Secured wireless network and open internet...

    I own a camp ground and  have people using my internet and I found out last week that could see in my laptops because I have a network and share files with all my computers. I am using a Wireless G router. Can I secure my network and leave the internet open to the people????   Thanks for your help....

    Another possible solution to you problem is to replace your current router with a router that supports multiple wireless networks, like the WRV200.
    The WRV200 allows you to setup 1 to 4 wireless networks.  These networks exist on separate secure VLANs (virtual LANs).  All of the networks can share the same Internet connection, but otherwise, their files are kept separated.
    The router sounds expensive, but I found it at CDW for $80.
