Good day sir,i have a new safecom router adsl swam 45108. I connected al components orderly,but when I open fire fox and typed the router's ip address 192.168.1.1 , or 192.168.10.1 , and this is the router ip 192.168.123.245 from producer, still ,it will not display the router interfaces for setting . When I ping the router ip in command line , it will say time out . And I type ipconfig it will say media discontented. to me every things are fine,because the router has the full light, wlan light ,and it was ful network connection on the monitor . Pls , tell me how do I get the router picture on browsers for settings . I use hp compaq, win xp professional ,service pack two ,no driver problem . Pls help thanks. Ibramus94@yahoo.com

You must use a wired connection between your computer and your router during the initial set-up.
