My computer keeps telling me I do not have an internet connection when I connect my router. I can unplugg the router and plug it back into my dsl modem and the internet again works. why won't my router...
More info would be helpful, but I am assuming that you have a router device that is not the DSL Modem, maybe a linksys, or something? Most likely what is happening is that the DSL modem is assigning private IP addresses, like 192.168.1.x, and the router is obtaining that IP address on its WAN interface, but is also configured for the LAN at 192.168.1.x, which is the same subnet, so it cannot route packets to the internet properly, as both interfaces have the same network range. Can you give me more info? I can try to walk you thru step by step.
Step 1. Verify current IP address when internet connection is working. (Go to a command prompt and type ipconfig, press enter, and document what your IP address is, also document the gateway address and subnet mask)
Step 2. Connect to the router instead of the DSL modem, do the same thing, document your IP address, gateway, and subnet mask
Step 3. Compare the two, your IP may be different, and the gateway may even be different, but see if both are trying to use the same IP range.
If they are the same, or close (the first 3 octets(set of numbers) are the same) then you will need to configure the lan side of either your DSL modem, or the router to be on a different IP address.
To do this will vary depending on the model of your router, so if you respond in the next few hours, I will still be online, and will try to assist.
