  1. So,currently I have a modem in the living room (Cisco EPC3208) and then it goes all the way to my room to a Cisco WRTG54V1 router. Yesterday out of the blue it stopped working, This is because I previously had 2 routers in the network (Asus and Cisco) anyways I decided to disconnect my asus and use only the cisco,but the router just won't work,I reseted it to it's fabric settings. But when I log into it it says the router's IP adress is 0.0.0.0 ? And hands out IP adresses to my pc such as 192.168.1.103,I have no idea what to do!

    Have you tried pressing the reset button on the router? (long press)
    I have seen this 'reset button' on several router brands/models like tp-link (tl-wr941n, tl-wr740n old version, tl-wr740n newer version), buffalo draft-N routers, cdrking routers (made in china router brand sold in the Philippines).

    if the reset process I described is the same as what you typed in your first post, try to manually change the router ip address.

    my wimax modem ip address = 192.168.1.1
    so for the tp-link wr-740 router, I use ip address - 192.168.0.1

    login to your router and change it. if there's any save button, click it. my router prompts me to reboot the router. after a few seconds, the preferred ip address I have chosen is good for use.
    (I have hidden my MAC address)

    Afaik, the second pic 'ScreenHunter_04 Jun. 25 11.16.png' is good. if not done, click 'save settings'.
    the ip address is set to start at 192.168.100 so the 192.168.103 assigned to one connected device is good.

    the first pic 'ScreenHunter_04 Jun. 25 11.02.png' however shows incorrect date.

    questions:
    1. is one of your two routers configured as 'router' and the other configured as 'repeater'?
    if yes, read some info here and here. you may need to skip ads.

    2. did you access the router using a cat5e/cat6e LAN cable connected to one of the LAN ports or the WAN port?
    I have seen the date error only in only one cdrking router in which the WAN port is dead. other than that, I have no more idea.

    The first display
    and the second
    ARE BOTH PERFECTLY GOOD :) (y)

    your test should be (using the command prompt)
    1) ping a site by address eg: ping 8.8.8.8 and you should get timing values and no errors
    2) ping by name eg ping google.com and that should work too but also proves you have DNS name resolution.

    SO, What makes you think there's something wrong with these values?

    At jobeard, take a look at the OP's attachments. the first screenshot picture shows an incorrect date, not available current time, no ip address/gateway values.

    Hmm; that looks like a WAN side page.
    From the inital display, the LAN side is just fine.

    use the browser to access 192.168.1.1 and it will be clear that the Lans side settings are fine. Access the WAN side and you'll see what the ISP handed out - - much more likely that the WAN is fouled. Power cycle the router and it should get good ISP configuration.

    this is what I suspected: the WAN port is dead.

    I read somewhere that some router brands/models can be 'flashed/reprogrammed' such that when the WAN port is dead, one of the LAN ports can be configured as the new WAN port. I have not done this port reprogramming.

    Make sure that the wire from the modem goes directly into the WAN slot of this router. As there were two previously, it might be connected to a LAN slot instead.

    hmm - - don't think so UNLESS you're speaking of the dd-wrt firmware replacement. The LAN side of a router acts just like a switch, ie: does not implement DHCP but only sends packets to their destination. Only the WAN side implements NAT, SPI and DHCP.
