Internet connection through router

By Hodsocks
Feb 1, 2005
  1. I seem to be having what I consider to be a strange problem, I have 2 ways to connect to the net, through a USB broadband modem or through a ADSL router.
    I connect through AOL and have Norton Anti-virus and Firewall installed.
    If I connect through the modem I have no problems at all, I can access all sites and can check mail, surf with IE6.
    If I connect through the router I have problems with some sites not opening and problems with mail. However if I go to the same sites using the AOL explorer they open without a problem.
    I have connnected another machine through my router and have had the same problems and this machine has no firewall or anti-virus in place so I am assuming that it is a problem with the router itself.
    The router in question is a Linksys BEFDSR41W, I have checked all the settings and they seem OK,
    Has anyone any suggestions as to what the cause of the problem may be?

    are you using the router between the comp and the modem
    you might want to change the MAC of the router to the MAC of the comp and see if that works

    No. the router has its own built in ADSL modem, so the computer is connected to the router with cat5 cable and then straight to the phone line.

    what does AOL tell you to do your settings
    I think AOL uses a co. called SBC for dsl service you may try there web site to config modem

    What software are you using to surf the Web with when using the router, IE6?

    Yes, IE6. some of the sites I can't get into are Microsoft, MSN, banking yet others open without a problem.

    In my setup at home, I’ve got a DSL Modem/Router which is set to bridge mode, so it just functions as a modem. Next in line is a router/switch unit (Dlink 707-P), which works as a DHCP “server”, with SPI/NAT firewall and IP-filter .

    So, potential problems with the router are, in my case, often related to the (router’s) firewall (likely the SPI portion) or the IP-filter, where specific IP addresses, including ranges, can be eliminated or re-routed, or you can exclude sites based on key words, etc.

    The other problem I’ve seen arise is where a router (DHCP enabled) is installed on a system with a computer that has the ISP’s client access software (or some remnant of it) still running on the machine.

    My apologies if this just covers old ground. I’ve asked a colleague in tech support to check out AOL vs. IE6 on the AOL network. If he comes up with something, I’ll post it directly.

    Under Internet Settings, have you reviewed Privacy rules and the Advanced Settings for enabled filters?

    go to your firewall settings you may need to add the routers default address
    I use 192.168.1.1
    good luck

    Norton Firewall is on my pc but even if I disable it I still cannot access the sites.
    The other pc I tried to connect did not have any firewall on it.
    The firewall on the router only seems to give me the option of disabling it completely, no settings to alter.
    Storm...I will try some of the recommendations in that article, happy to try anything right now.

    I have tried the resetting of the dll file and it made no improvement I am afraid but there are some other articles in the site that I want to try, eg resetting TCP/IP and DNS.
    I am not convinced this is the answer because I have no problems accessing all pages using the USB modem, but I am happy to give it a try.

    can you get to the router's web interface? If so, go to the status page and see if the router has been given an IP by the modem.

    Storm....The router and modem are one unit so there is no interface.

    There has to be some way to get into the router to configure options such as wireless security, SSID, DHCP server settings and other router functions.

    I tried to look up your router/modem combo at Linksys and don't see it, I see a BEFSR41 but not a BEFDSR41W(I did a search at Linksys and did find a press release about it from 2002, but no user guide or other useful info).

    I found this ;look on left your box is listed
    http://linksys.custhelp.com/cgi-bin...XJjaF90ZXh0PUJFRkRTUjQxVw**&p_li=&p_topview=1
    seems you should download the software utility file maybe thats why you can not get access.How did you access the modem to config for internet logon?
    problem could be in there.
    once you do that you should be able to type in the url address in browser
    192.168.1.1 this is the default address for the router side of your box
    have you contacted your provider and do they support the linksys modem
