How to Setup Linksys router as access point
If you have an existing wired / wireless network, then you can use Linksys E1000 router as access point. You can not use the Linksys E1000 router as a wireless bridge or wireless repeater.
Connecting any router as an access point is just like connecting a router to another router (LAN to LAN connection type)
Suppose you have a wired router and you want to convert the existing wired network into wireless network, then you can use the wireless router as access point. It is just like connecting 2 routers to each other also called as cascading of routers.
You can also connect 2 wireless routers to each other to extend the range of the wireless network. If you are connecting 2 Linksys wireless routers to expand the range then there should be a cable connected between these 2 routers. You can not connect 2 routers to each other wirelessly. That is called as wireless bridge.
Suppose you have a wireless router WRT54G connected to the modem and you are able to go on line using this router. Now you want to connect the E1000 router to the existing network. First check the IP address of the WRT54G router. Let’s consider the IP address of the WRT54G router is 192.168.1.1. Then you can change the IP address of the E1000 to 192.168.2.1 and connect the cable between the WRT54G router ( LAN port 1,2,3,4) to the Internet port of E1000 router. See Video ==>
Make sure that the SSID of both the networks will be different so that there will not be any confusion. You can keep the same password.
If you want to use the E1000 router as a wireless switch then you can change the IP address of E1000 router to 192.168.1.2, disable the DHCP server , and connect the WRT54G router ( LAN 1,2,3,4) to Ethernet 1,2,3,4 port of the E1000 router. In this case the WRT54G router will provide the IP addresses to all the devices in the network and E1000 will just act like a switch.
