I have a PC that is connected to ADSL Modem router (linksys WAG54g2) directly via Ethernet cable And a laptop and also other devices such as another laptops and smarth phones. However when I turn On the PC or turn it off, some strange problem happens. My wireless network seems connected on laptop but there is no internet activity and can't open a webpage until I turn router off and on again manually. (other devices including the PC itself can't use the internet either) My router configured this way: Encapsulation: RFC 2516 PPPoE Multiplexing: LLC DHCP Server: Enabled and network sharing center IPv4 configuration is obtain IP address automatically How Can I fix this issue?
