I connected my bsnl broadband to my computer with lan cable. My Computer OS is Windows Ultimate. I can connect to WLAN to my android phone but I can't open 192.168.1.1. I can't open 192.168.1.1 in my computer also. Then when I type ipconfig/release it came with no problem but when I type ipconfig/renew it takes more time and tells me that "An error occurred while renewing interface Local Area Connection :Unable to connect to your DHCP server."
