    Folks,
    I have a 2 computers connected to a Linksys BEFSR41 router which is connected to a Verizon Westell DSL/Cable modem. From time to time the Ethernet link between the modem and the router spontaneously disconnects. I can reconnect the link by going to the setup menu on the router with a browser @ 192.168.1.1
    Sometimes I have to do an ipconfig/release and renew to fix the link. Sometimes I have to power cycle the PC and the modem and the router.
    Currently this disconnect problem has gotten much worse. It occurs about every 15-20 minutes while I'm connected to the net. It also occurs when either computer is booted or turned off (I see the link light on both the modem and the router flash red for a moment).
    The problem never happens if only one PC is connected to the router. Do you think I need a new router?

    Does it matter which one - or do they both work on their own OK
    interesting that the Modem Lights also flash - ..

    you may want to try updating the router firmware

    Either PC works OK by itself! By the way the OpSys on both PCs is WinXP Pro, my ISP is Verizon and the connection is DSL. After either PC is booted and connected to the Net I can plug the second PCs Enet cable into the router and it works too.
    Router Model is Linksys BEFSR41 firmware is v1.36 dated Oct.5,2000. Linksys says this is the latest for this model.
    I used to have a company phone line at my house and used an identical Westell modem to connect to work via a VPN. I swapped the modems but it did not fix my problem. I also tried to replace the router with a never used Linksys BEFW11S4 but could not connect to it using Firefox or Explorer and URL 192.168.11 to get a set up page. That's when I contacted this forum.

    lets see a ipconfig /all from both PCs connected to router and when working

    ------------------------------------------------------------------------
    {ipconfig /all}
    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here
    We would like to see the results from ipconfig /all post back the results here
    -> Start
    -> (XP - enter the following in the RUN box)
    cmd /k ipconfig /all
    -> (Vista or Windows 7 - enter the following in the Search box)
    cmd /k ipconfig /all

    A black box will appear on the screen -
    rightclick in the box
    select all
    enter
    control key + C key - to copy

    then reply here and
    control key + V to paste
    ------------------------------------------------------------------------

    I thought you would ask for this. I did the HP ipconfig/all when I first read your first reply. Later I plugged Enet cable from the alan3 machine into another router port. Both are working. Apparently when alan3 was connected to the router it got a new lease. I can tell by the time stamp.
    By the way, alan3 is an Asus M2N motherboard machine I built from parts.

    well they look OK and have a seperate IP - and on DHCP

    it may be worth loging into the router and making a note of all the settings and then reset the router back to factory reset and reconfigure the settings - see if that helps

    Will do. This will take a while especially since my wife is having a Quicken problem.
    Thanks, talk to you later.

    Yesterday I reset the router and restored the settings. The problem did not change. I also tried to swap modem and router but was not successful.
    A friend of mine, Jim, was a Verizon DSL customer. He switched to FIOS and gave me his Westell 7500 modem/router. I tried to use it in my network. I hooked it up, reset it and worked through the setup pages.
    The lights on the 7500 and its menus told me I was connected to Verizon’s DSLAM. I was a bit surprised to see that Jim’s name was still listed as the subscriber. When I tried to connect to the net I got a page, that I think came from Verizon, telling me that I needed to restore my account. I entered my account # and password and then got a message saying that I had a valid account but had to call Verizon. I tried but you must know that it’s almost impossible to get a Verizon IT rep on a weekend
    I restored my old equipment. Now when I boot my PC (both connected to the router) I still get a red flash of the WAN light on the router but not the Link light on the modem and the router did not disconnect. Go figure.
    I’m going to try to install the 7500 again, but I’ll wait until late some weeknight when I have a chance of talking to someone at Verizon IT.
    I’ll let you know how that works out.

    I'm not sure about the 2nd router - as verizon may use MAC address to validate the modem so that maybe the issue as you have now connected with a device with a different mac address

    is there any reset on the modem at all?

    etaf,
    I got a new Westell 7500 modem/router from Verizon today. Installed it and the disconnect on boot problem seems to be solved. Thanks for your help.

    alan
    ps. I want to correct an error I made in describing the state of the Link light on the old Westell modem. It doesn't turn from green to red it just goes out.
