BEFSR41 to WRT54GC networking problems

    Greetings all,

    I searched the forums and came up with some posts that went over networking a WRT54GC but not to a BEFSR41.

    Here's my set up:

    cable modem----->BEFSR41(>3 computers

    BEFSR41----->WRT54GC(>1 computer

    My problem is I can't get the computer hooked up to the WRT54GC on the web. I hooked it up to one of the LAN ports on the back of the GC and I get nothing. I can't even ping

    I have the DHCP enabled on the BEFSR41. It's also set up as a gateway with tx and rx disabled. (I have no idea what tx and rx stand for. My guess would be Texas and prescription...that's how much of a newbie I am.)

    On the WRT54GC I've tried setting it up as a router with DHCP disabled, router with DHCP enabled, gateway with DHCP enabled. I might've missed a few things I've tried.

    What I want to end up doing is hook a computer up to the GC and surf the web and look at shared folders on the computers that re hooked up to the 41. I also would like to do this wirelessly.

    Any suggestions would be greatly appreciated. Thank you

    Thank you. That was fast. I just started looking at that Easy Answer when you posted.

    My next question would be, "Should I connect the cat5 cable from the 41 to the internet port on the GC or just connect it to one of the LAN ports on the GC?" If I do connect it to a LAN port then would I still be able to access the setup for the GC?

    Again, thank you for the quick reply.

    The GC also requires me to pick whether I want to use it as a gateway or router. I'm going to assume that I should pick router or did my assumption make an a** out of me? hehe

    Got it fixed for now. I can at least access the internet if the laptop is connected directly to the 54GC router. Going to try the wi-fi now.

    What I ended up doing was disabling the DHCP on the 54GC. Set the 54GC to router and then plugging the cat5 from the 41 into a LAN port on the 54GC....not the Internet(WAN) port.

    Just thought I'd post that solution in case anyone else has the same problems.

    Thanks again for the help.

    I've been trying to get something similar working over on the WRTxxx forum.

    WRT54G to WRT54GC Routing through WAN Interface

    I tried the Linksys procedure in this thread, and I think it did work at first but then it stopped working. Ater trying several times to recreate it, I finally gave up. I had thought the magic was the IP, but I guess not.

    Originally I was trying to create a netowrk with 2 different subnets. I eventually gave up and used the method you described, plugging the first router into the LAN port of the second. I'd still like to free up one of the LAN ports and use the WAN port, but I'm getting the feeling that this is impossible with the GC.

    I tried that but it didn't work. One thing not mentioned is that you need to add sa tatic route on the first router to tell it how to get to router 2's subnet. Even after doing this, inbound requests to the second router never made it. The best I could do was to have outbound only from router 2.

    How about putting assigning router 2 a static IP from router 1 and putting router 2 in the DMZ?

    I don't think you can put the router in the DMZ, only a single IP on that router. It seems simple enough to do, basically tell the 54GC to act as a router only, but I can't seem to set this up. Setting operating mode to either router or gateway does not seem to make a difference.

    One question I have is do you need a cross over cable if connecting from a LAN port on a 54G to the WAN port on the 54GC? I've tried both cables and neither work, but I'm just wondering which one is right.

    I'm a network newbie so everything I say is just me talking out loud.

    Can't you give the router (54GC) it's own IP addy and put that IP addy in the DMZ? It seems like you should be able to since you're plugging the 54GC into a LAN port on the other router.

    I couldn't get my GC to work using its WAN/Internet port and I used a straight through cable. Not sure if a cross over would have worked. I'd have to defer that to the other people that know what they're talking about.

    Sorry I couldn't be of more help. Maybe some day before I die I'd be able to actually answer questions instead of ask them hehe.
