need help configuring wrt54g2 ( while connected to 3com as my main router )

I need help configuring my linksys router wrt54g2 , some details , my main router that is connected directly to the internet is 3com , i took a Ethernet cable from the ports of the 3com and connected it to the linksys internet port , i need my link sys to work as a switch / wireless using the connection at the 3com's router , my 3com router IP is 192.168.1.1 , link that may help u here , but i don't know why did he configure the main router as 192.168.2.1 Cascading (Connecting) a Linksys ADSL Gateway to a Linksys Router
thanks in advance

 

In order to make it work as a switch you need to disable DHCP on it. Assign a Static IP to the router, outside of the DHCP range of the 3com, this allows you to log into it for admin. Then connect lan to lan.

You will need to connect via lan to the wrt54g to make the changes.

 

thanks i made it work by connecting the 3com port to the internet port at the linksys ,then using the CD to configure automatically , and after that everything worked , until linksys after 30 min started freezing (and won't work without a hard reset ) , this happened like 4 or 5 times in 2 hours , it appears that i got a faulty unit , and i ll be sending it for replacement :S

 

You do not want to use the Internet port unless there is a setting to change every thing over to an AP/switch.

Your freezing may be do to IP Conflict if you did not follow my directions.

 

there was no ip conflict cause my pc was the only one connected when testing , and i know how to avoid IP conflict , anyway i got it replaced and got a netgear , netgear is alot better than the linksys model i got , better wireless range / more options , cheaper
