Hi,

(apologies for this newyear post)

My linksys WRT54GL router flashed all the latest firmware installs: dd-wrt v24 sp2 sp1, openwrt backfire/10.03.1-rc6, (again) linksys 4.x, tomato v1.28.1816. Configured them all. Did not mangle with the bridge setup (ip route, iptables et al), nor with numeric WiFi params.

Ok. did everything from wired ethernet; then enabled remote (https) access. Now am in a ssh tunnel to VNC/job via WRT. Linux OS on laptop client. Router WAN with DHCP from cable TV modem; gave up dhcp on clients, static assingments now. WRT is setup as "gateway".

Ok, host-woods works from client via WRT dnsmasq, ping the WRT IP works; i.e., local subnet "waves" around, but no outside network connection at all, except from ssh'd WRT itself and wired ethernet (+ WRT ssh tunnels half speed).

Found many forums saying: restart modem, restart WRT, no solution, bad IP, reset conf, reinstall firmware, renew DHCP... when suddenly out of luck my android smartphone goes browsing and youtubing on the same ssid. So WRT is not the issue. Kernel 2.6.29 on android and 3.1.5 on laptop.

WPA2 is setup, the local wireless subnet too, but no outside (no ping, no google, no ssh) connection from linux 3.1.5 laptop with wpa_supplicant invoked with args:

-Dwext -c /etc/wpa_supplicant/wpa_supplicant.conf 

This used to work on previous 802.11n router which I switched for the WRT54GL linksys 802.11b/g.

So, android has internet via WRT, laptop not; same WPA2 and SSID. Where is the difference? It would seem instead of routing to an internet address via WRT, the client takes the address be on the same subnet, because it keeps ARPing for global IPs.

Appreciate any help, thank s.

I inserted the output of `nvram show' (tomato) and of `tcdump -vi wlan0` while attempting to browse "mail.google.com" on client. Conf is simple, just for net, all extra opts are disabled. The IPs 192.168.1.111 for WRT and 192.168.1.222 for client are general.
