Default Linksys WRT54GS - which version?

I am looking to buy a Linksys WRT54GS router. I am wondering which
version (1-5) should I get? I always thought I should get the lastest
version but from what I read v5 has some sort of issues. Is that true?

I have two desktops and two laptops. All XPs. Besides browsing, I do
bittorrent, file sharing between computers, and VPN to my company
network through my laptop(wireless).

Thanks in advance.

Be aware that there is a WRT54G <-- note no S (for Speedbooster), that has
version concerns and goes up to version 5, but the WRT54GS model (note is
HAS the "S") is only up to version 1.50.8.

IE If you are looking to buy a WRT54GS, then you can ONLY get them with
firmware up to 1.50.8.... Never higher and no problem with the firware from
OTHER models (like the WRT54G is a totally different model)

That said, the S (speedbooster) only appears to work between manufacturer
specific devices... (chances are most laptops don't have linksys stuff in em
and can't use the speedbooster anyway)..

Personally, I suggest people get the older models of WRT54G (walmart has em
for under $48, but make sure it is less than version 5), rather the GS model
for about $79, and probably won't work with what you have, any faster than
the one that's cheaper....

Interesting that you seem to confuse hardware versions with firmware
version between the two lines. There are indeed hardware versions of the GS
line which run through version 5 just as with the non GS WRT54 series. What
I find interesting though is that you talk about the plain G and use the
hardware numbers but when you discuss the GS series you only refer to the
firmware numbers without mentioning that you have changed from 'apples' to
'oranges'. Is this because you don't know about the GS line or that you
wanted to be confusing?

Just to assist you in knowing your subject better in the future consider
reading this wiki:

http://en.wikipedia.org/wiki/WRT54G

fundamentalism, fundamentally wrong.

Nah, I know it VERY VERY well, I sell them, have 8, and the manufacturer
website (www.linksys.com) says exactly the same thing..... Your stuff is way
wrong.... Maybe you should consider changing your tagline to "Rico,
Fundamentally wrong"... :)

According to:

http://wiki.openwrt.org/OpenWrtDocs/...inksys/WRT54GS

The WRT54GS versions seem to parallel the WRT54G. That may be related to
the fact that the WRT54GL, which is equivalent to WRT54G v4, appears to
have the speed booster hardware. So maybe Linksys is just selling the
same hardware with different firmware settings to disable (WRT54G) or
enable (WRT54GS) the speed booster. Such practice is common.

Anything off-standards is unlikely to work between manufacturers unless
they share (e.g. sell) the technology. This Speed Booster stuff is very
much non-standard. The other end has to also have it to use it, and that's
just not really worth it IMHO.

You may want to look at the manufacturer's site and get the correct info,
rather than an incorrect wiki (seems like they have the same info for g as
the gs), at the manufacturer site, they have different info and different
firmware (different dates and file sizes)...
WRT54G
http://www.linksys.com/servlet/Satel...VisitorWrapper
and The WRT54GS

Thanks for the replies. I think I am going with the WRT54G instead.
Back to the question, should I get v4 then since v5 and above has less
memory and not compatible with 3rd party firmware?

If possible yes.. FYI, you can usually find the older ones at walmart
(walmart?!?! Yup.. they sell pallets of the older ones to walmart, and then
they sell em cheap (about $47-$48 bucks) look for any of the v1 thru v4's
(like I said, sometimes they get older ones, and older versions are by
definition older)

Go to the linksys download area and lookup WRT54GS ver3 and WRT54GS ver5.
Different firmware.

If you can find a version4, yes. Try shopping ebay as the version 4 and
lower have been out of production now for about a year (more for the older
versions).
It isn't so much the reduced memory as version 5s were allowed to ship with
'defective/buggy' firmware. There are fixes now, but it is hard to know
looking at the box if you have the 'fixed' firmware.

Also another option is to look for a wrt54GL (note the "L"). This is
basically a version 4 with a higher price.

But take a look at on ebay.

What serial number range would that be since hardware version is not
written on the outside of the box, but you knew that since you sell them?

Does the Linksys Speed Boost interfere with other routers ?
I remember one reference on Tech TV at the time that the Speed Boost
worked by interfering with neighbour's routers.
I only remembet the one reference and do not know if it is correct or
not
As well I do not see how the one router could interfere with the others
in the area but not itself .

You may want to take a look at the seattle wireless website page, has much
more accurate info...
<http://www.seattlewireless.net/index.cgi/LinksysWrt54g
Or toms networking at http://www.tomsnetworking.com/ (you'll have to follow
the pages)

Oh, And this note on V5 units..Version 5 WRT54G units have serial numbers
beginning with CDFB, Avoid them like the plague!

Some speed boost technology works by using more channels, which creates
more interference, and isn't neighbor friendly.

Not much higher. Plenty of good pricing around.

No. Linksys uses Broadcom's Afterburner system which uses only the
usual 22MHz of bandwidth. It's Atheros Super-G and Super-AG that
clobbers that adjacent systems. It combines two 22MHz channels to get
the advertised speed.

I think both "no" and "clobbers" are a bit strong. See
<http://www.tomsnetworking.com/2003/11/30/atheros_super>
<http://www.tomsnetworking.com/2003/12/07/atheros_super>
<http://www.tomsnetworking.com/2004/04/01/linksys_wrt54gs_wireless_wrt54gs/>

The criticism of Super G is largely based on a Broadcom PR campaign
against the initial (arguably premature) release of Super G, tainted by
apparent envy and sour grapes, since Broadcom had nothing comparable,
and since Broadcom products were the ones most affected by Super G.
Tests showed that interference even from initial Super G was only a
problem when (a) Super G was running at full tilt and (b) the other
network was within 50 feet, conditions that won't normally be met.
Current Super-G products are designed not to interfere with non-Super-G
products.

While 125 High Speed Mode (125HSM, originally called Afterburner),
Broadcom's belated response to Super G after the relative flop of
Xpress, is probably more neighbor-friendly than _initial_ Super G, I've
seen no real evidence that it's significantly more neighbor-friendly
than _current_ Super G, and it's less effective than Super G. (From the
last article above: "On the other hand, as Figure 7 shows, Afterburner's
speed drops pretty quickly with distance and / or obstacles - enough so
to question whether Afterburner provides any significant benefit under
real-world conditions.")

I'll confess to not staying up to date on Super-G versus Afterburner.
Let's see what I find:


http://www.tomsnetworking.com/2004/0...gs/page11.html
Netgear and DLink use Super-G (Atheros), Linksys uses Afterburner
(Broadcom), and SMC uses something from TI.

At an average throughput of around 50 Mbps, the NETGEAR products
using Super-G clearly beat Linksys' Afterburner-based offerings,
but only when Super-G is running in its controversial
channel-bonding mode. As the plot shows, Super-G drops out of
channel bonding on a periodic basis to ensure that non Super-G
products get a chance to communicate, which lowers its average
best-case throughput to about 45Mbps.

What this means is that the improved Super-G uses channel bonding only
when it has exclusive use of the channels involved. A bit of personal
testing showed this to be the case only on Ch 6 (the center channel).
It doesn't listen on the adjacent two channels.

The Tom's Networking URL's are from 2003 and 2004. This is slightly
later and still shows a problem:
http://www.54g.org/pdf/TollyWP204120...-printresA.pdf
See Page 7 for where the thruput on a Belkin F5D7230-4 droped 94% when
operating near a Netgear WGT624 in Super-G mode. The Belkin was
setup to hunt for usable channels during the test. It didn't find
any.

Change apparent to obvious. Broadcom was more than a little obnoxious
with their smear campaign. However, they were initially correct about
channel bonding problems.

Digging a bit deeper into Super-G at:
http://www.tomsnetworking.com/2003/1...er/page13.html
Updated December 6, 2003 A Super-G WLAN running at full speed
will seriously interfere with an 11g WLAN running 2Mbps streaming
video even at 30 feet. The interference is essentially gone at 50
feet.
I'll assume they're talking about interference on the adjacent
non-overlapping channels. Yeah, I'll buy that. It's only a problem
in close proximity. Add 6dB of antenna gain, and the 50ft becomes
25ft. Add 6dB of antenna gain on both ends, and the 50ft becomes
12.5ft. In other words, with the stock rubber ducky antennas, 50ft is
safe. With better antennas, it's not.

>Current Super-G products are designed not to interfere with non-Super-G
>products.


No. They're designed to disable Super-G channel bonding if there's
anything on the channel. The problem is that they don't seem to be
listening (my guess) on the adjacent channels. Only on Ch 6. This is
not exactly my idea of non-interference. Locked in channel bonding
mode, they generate quite a bit of RF on the adjacent channels.

I only have some spotty experience with both Super-G and Afterburner.
In both cases, I turn them off. The problem is the same as with
802.11b compatibility in an 802.11g router. The receivers can only
decode the mode if it "scans" for it. If it's listening for 802.11g,
it won't hear an Afterburner or Super-G (channel bonded) signal. So,
it time slices the receive listening for 802.11b, 802.11g, and enhance
modes respectively. I spent a few minutes trying to deduce the
algorithm used and just gave up. My current policy is to disable the
enhanced modes and run in 802.11g mode only (if possible). For public
access systems, I'm stuck with 802.11b mode only, or possibly
802.11b/g compatibility mode. Anyway, it's for this reason that I
don't have much experience with the enhanced modes. I always disable
them.

Here is a detailed listing of all WRT54G and GS router versions and how
to identify them both inside and out. (And contrary to at least one
poster, there are 7 versions of the GS ranging from 1 to 5, just like
the Gs)

I've got a fair amount of experience with Super-G (more than with
Afterburner/125HSM), and I've just not seen the kind of problems you're
suggesting in the real world. For example, not too long ago I did a
SOHO setup with Super-G, was able to test the results carefully at a
number of nearby Wi-Fi-equipped neighbors; and found no measurable
interference with Super-G enabled, even when running at full tilt, which
was quite a bit faster for my client than with it disabled.

While it's certainly possible to demonstrate problems with artificial
tests, that's true of many things that work well in the real world.
