    I am using a modem at bridge mode and WDR3600 as openwrt router. .I have a cable from modems LAN to WDRs WAN and a cable from WDR to pc. I have connection via cable. From 192.168.1.1 when I select to enable wireless ,it highlightes the Generic MAC80211 802.11bgn (radio0) but I have no connection (signal is 0% and bitrate nothing). (I am not sure what to do with radio1 device though)

    /etc/config/wireless

    config wifi-device 'radio0'

    (I am not sure what mode to select also,'ap' or 'sta' )?

    Ok! I had to check 'lan' network from wireless (rasdio0) settings and it works!

    router - Routed AP using OpenWRT
  • Oz123

    Background

    I want to use OpenWRT in to enhance a relatively week signal in one part of the house. The FritzBox router is located far away, and must stay at the top floor. I can't use cables.

    Partial Solution

    I am following the Routed AP Guide in the OpenWRT wiki, but I can't get my clients from the lan I am setting to ping WWW. So here is what I have:

    1. Fritz!box which I am only allowed to have the WPA key to it. The box issues IP's in the range: 192.168.178.0/255 (ESSID: "FRITZ!Box")
    2. My OpenWRT router (with Atheros Chip) with Backfire (10.03.1, r29592). My router is giving DHCP with the range: 192.168.1.127.

    Observations

    Before, I followed the guide, I entered the GUI and connected the Router via Wifi->Join to the LAN network of the FRITZ!Box. The client connect to OpenWRT has the address 192.168.1.128, and can access WWW. From the OpenWrt shell I can also ping WWW.

    After Issuing the instructions in the guide, replacing the correct IP addresses where needed. I restart everything as said, and I can connect to the new WLAN established with the name TEST.
    From my single client in that WLAN with the new IP 192.168.178.229 I can now ping the Fritz!Box at 192.168.178.1 and my OpenWRT at 192.168.178.40.

    However, I can't access WWW from client (192.168.178.229) or the OpenWRT router.

    One, more observation, which might help solving my problem: I have a bridge defined (by the automatic tools, i didn't add it...).

    Extras

    ### ip route default via 192.168.178.1 dev wlan0

192.168.178.0/24 dev wlan0  proto kernel  scope link  src 192.168.178.34

    Can't find ip route on the OpenWrt router.

    Question

    What prevents my packets from going from my new WLAN "TEST" to the old WLAN "FRITZ!Box" ?

    Thanks in advance, Oz

    Packets reaching the internet router is a good first step so far. Maybe the default route is not set up either on the repeater/wifi relay or on the client or on both. Can you check what "ip route" says on the relay and on the client?
