How do i connect a wireless router to a switch which is connected to a wired router?

My existing connection is a wired router (Router No.1) connected to the DSL. I added a switch to the wired router for the other PCs. I recently added a wireless router (Router No.2) to the switch I succeeded in getting connected WIFI to the internet and the other wireless PC. My problem now is that I cannot connect to other PCs on the network that are wired to the switch and vice versa.How do i connect a wireless router to a switch which is connected to a wired router?
Wire Router to Switch to Wireless Router make a more traffic of your wireless client.



Why u dont remove wired Router and replace your Wireless Router?



Or



How many Ethernet Port of your wireless Router? If ever have

an vacant Ethernet Port then remove your switch connection to Wire Router and

connect it to wireless Router?



Or, try to check your wireless router and disable DHCP.
