Using a WRT54GL with PolarCloud's Tomato 1.28. Have experienced the following issues: -Two separate machine running Ubuntu server 12 LTS do not show up as devices (do not pull an IP via DHCP) when connected via ethernet ports. Multiple Windows 7 machines pull an IP via DHCP when connected via ethernet and work as desired. I am no computer expert. But basics such as a bad ethernet cable or machine specific issues have been eliminated as possibilities. -Samsung tablet connects via Wifi (shows up as a device) but has no internet or LAN connectivity. Even going to 192.168.1.0 (router address) does nothing. Tried setting a static IP from the tablet, did not resolve issue. Have not tried connecting via any other wireless devices. Does anyone know what is going on? Specifically does anyone know if these issues are router specific (bad hardware), firmware specific (old firmware), setting specific, or something else?
