If you're using the Linksys BFSR41 you'll only be able to connect the WRT54GS to the LAN port on this router.
ABOVE NOT TRUE!
I have a BEFSR41 "wired"
and a WRK54G "wireless" router
I have 2 wired Desktops, VOIP adaptor, a TIVO & XBOX thats 5 wired devices Plus my note book but thats what I need the wireless for.
I was having to un hook my TIVO if I wanted to use the Xbox on line, so I thought why can't I use my older BEFSR41 for more ports?
I went to linksys and I did what the knology Base said to hook them together but it did not work?
They stated to hook 1 pc up to the wired router and the cable modem, and then go into the set up turn off DHCP change the last number of the LAN IP Address to 2 in place of 1 and save your settings then hook your PC and Cable modem back up to your wireless router.
Have 1 of the 4 ports free on your wireless router "Note that the wireless router should be Router #1" hook a network cable in to one of the ports on the wireless router and then into the uplink on the wired router..
Well that did not work, so I called Linksys they informed me that the problem was That I used the uplink ...I was NOT to use the uplink but 1 of the 4 numberd ports on the back of my BEFSR41.
That worked !
the wired router has my cable modem in the wan port.
port 1 has PC 1
port 2 has PC 2
port 3 has my VOIP adaptor
Port 4 has a network cable in it that hooks to port 1 of the BESFR41
port 2 of the BEFSR41 has my XBOX
Port 3 has my TIVO
Port 4 is free for when I work on some ones PC I kan hook it right up.
All is working well...
I hope this helps some of you, and I must say I was shocked that there i s still a company that has free tech support and people that know what they are doing.
a Big Thumbs up for Linksys!
