Default LinkSys WRT54G as repeater/Extender?

Hi,

I have a LinkSys WRT54G in my home but it doesn't cover all areas. I
want to extend the signal and am wondering if another LinkSys WRT54G
would work.

TIA,
Dan

Yes. Two ways to connect it:

1. Configure the 2nd WRT54G as an access point. Details and
instructions on request or just search this group. Run an ethernet
cable between the two WRT54G boxes between LAN ports. The WAN port on
the 2nd WRT54G goes nowhere. You can mix and match SSID and channel
assignments, but if you wanna try seamless roaming, they should both
have the same SSID and be on the same channel.

2. Use WDS (wireless distribution service). This works the same way
as the wired solution previous described, but without the ethernet
cable. However, there is 50% reduction in maximum thruput going
through the 2nd router via wireless. This should not be a problem if
your backhaul (Cable or DSL) is much slower than your wireless
connection. For WDS, both boxes will use the same SSID and channel.

I would be using the wireless option and would like to keep the G speed.
Would going with the LinkSys G Extender be a better option then?

No. Range extenders or store and forward repeaters are a crap shoot
and often don't work. Search for "range extender" or "repeater" in
this newsgroups for all the "it doesn't work" horror stories.
Even if they did work, they have the same speed reduction issue as the
WDS bridge protocol, which is also simplex store and forward.

Be advised that the speed reduction is not as horrible as it sounds.
Let's say you get a 24Mbit/sec connection between the two WRT54G
routers. That will yield about 12Mbits/sec thruput to a wired
computah plugged into the 2nd WRT54G. If your wireless client now
connects to the 2nd WRT54G and gets the same 24Mbit/sec connection,
you will see half again or 6Mbits/sec thruput. However, if your DSL
connection is only 1.5Mbits/sec, the 12Mbits/sec is kinda wasted as
your 1.5Mbits/sec maximum speed will be limited by the DSL and not by
the wireless. As long as your wireless connections are faster than
approximately:
1.5Mbits/sec x 2 for overhead and x 2 for WDS = 6 Mbits/sec
then your wireless will not slow you down.

You can use WDS to infinitely extend the range, but each hop again
cuts the speed in half. Eventually, you run out of speed. That's
roughly why I thing mesh networks, with routinely do multiple store
and forward wireless hops, are a bad idea.

This 10 page series of articles:
http://www.tomsnetworking.com/Sectio...le78-page1.php
is worth reading so you know what you're getting into with WDS.

I ended up getting the LinkSys WRE54G Range Extender and it works
wonderfully. I like that I can plug it into a wall outlet flush and it
does support WPA (ver 2 fw). I did manual set up and had no problems.

Default Help with Repeater

I know this post is quite old, and I'm a total newbie to this group - so I beg your patience and indulgence with this question! :)

I have a Verizon FIOS router as my main router in my 3-story home. I'm getting a TERRIBLE signal in the basement of the home. So, after reading this post, I dug out my old WRT54GS and hooked it up this way:

Power outlet (of course)
Ethernet cable from LAN on Verizon router to LAN on the WRT54GS
Cable from Xbox 360 (which used to go straight into the verizon router) into another LAN port on the Linksys.

Make sense so far?

I set the SSID and WEP codes the same on both routers (although I THINK each is using a different broadcast channel). I gave the Verizon router the standard 192.168.1.1 IP address and gave the Linksys 192.168.1.2

So... here's what happens when I fire it all up - I get a solid strong signal in the basement from the Linksys and the wireless computer down there connects to the internet well. But it seems that the Verizon router stops putting out a signal, becuase the wireless devices in the upstairs now get a really weak signal! Ugh!

Any suggestions?!?

Thanks for helping out!
