If you have one of those 2wire modem/wireless routers, and your signal is not strong enough for you. You can connect a wireless router like the Linksys WRT54G to it, and then have a wireless access point like the Linksys WAP54G be set up as a repeater to repeat the wireless signal of the WRT54G. This will make your wireless signal a fair amount stronger, and it will reach farther.
The way to do that is by setting the 2wire modem/wireless router to “Bridge Mode.” It’s a pretty simple process to do this. It’s just one setting that needs to be changed. Call your ISP and have them walk you through it. Then, simply hook up the Linksys WRT54G to the 2wire unit, enter the PPPOE info if you have DSL into the Linksys router, and then set up the Linksys access point to repeat the Linksys router’s signal.
