Trying to set up linksys and medialink routers so that they have same ssid and same security credentials.

From my cable modem, I am connecting to my linksys [primary router].

linksys set up on

ip range from > .102

medialink[secondary] set up, dhcp disabled

I also have trendnet print server set up on

I set up the routers 1 by 1, then connected linksys to meidalink and powered it up.

I can see my AP on both routers, I made my secondary router to have no security, however when I try connecting on my open ssis [on medialink] I get no connection and somehow it kills the network in the sense that I cannot connect to my linksys without powering down both routers.

Not doing this via DD-WRT.

I am unsure where the flaw is in the set up.

  • Is the cable modem also a router or is it bridging? Are the two wifi routers connected LAN-to-LAN? What's connected to their WAN/Internet ports, if anything? – David Schwartz Oct 23 '13 at 20:52
  • The cable modem is not bridging. THink comcast do not brdige their modems by default – user266356 Oct 23 '13 at 20:55
  • The security on both routers is identical, right? Same SSID, same security type, same password? They're connected LAN-to-LAN, not WAN-to-LAN? – Josh Oct 23 '13 at 20:57
  • @user266356 If the cable modem is not bridging, why do you have DHCP set up on either router? Are you intentionally trying to set up double NAT? – David Schwartz Oct 23 '13 at 20:58

    What's your IP set-up on the MediaLink? Gateway, etc? – Josh Oct 23 '13 at 21:02

You can't have both routers numbered inside the same network but connected WAN-to-LAN. Either they're in the same network or they're not, you can't have half and half.

Change the router-to-router link to LAN-to-LAN instead of LAN-to-WAN. This will still give you a poor setup with double NAT, but at least it will mostly work instead of mostly not working.

Ideally, you'd switch either the cable modem or the other wifi router to just bridging. That way, you have no ugly double NAT.


Having a router behind another router is Bad News, for normally routers also provide other services such as DHCP. Make sure to bridge the second router so it just acts as a WAP and a switch. Me, I'd just get a wifi repeater which would require no extra management at all.

    Using a WiFi repeater would provide about 1/3 the bandwidth of two APs wired to each other. That would be the last choice if you had no other way to increase range. – David Schwartz Oct 23 '13 at 22:32
  • David's absolutely correct, if you can run an Ethernet cable from one to the other, that's superior to using a repeater. – K7AAY Oct 31 '13 at 18:34
