I have a Linksys modem around 3 years old. I found last week that its version to so old and so I should upgrade it. I went through the process of firmware upgradation and everything went proper except this that I am unable to access my modem now. It was previously configured by some product supplier's guy. So after upgradation I am not able to configure my modem in order to connect it to internet. Before this the IP was 192.168.240.50 but this IP is unrecognized by any of my web browsers. How can I find out what is the new IP address of my Linksys modem?
