I was hoping someone with expeience might help with a question.

I am going to have to add wireless capability to an existing network
for a friend. So, I know that I could buy something like a linksys
access point for about $80. I am also looking at the cisco which
seems to go for about $350. My question is this

What ist the real difference between the cisco and the cheaper ones ?

Thanks

- More MAC addresses handled on the Cisco

- Possibly higher transmit power on the Cisco [I have seen this written
but have not cross-checked for myself]

- The Cisco supports 802.1x authentication with LEAP, not just
the insecure WEP or WEP128

- The Cisco devices are still having features added to them through
software upgrades: you won't just get tune-ups and bug fixes, you
will get new features

- The Cisco devices are more likely to officially be able to change
antenna; for any given Linksys, you might be able to hack it, but the
result is probably not going to be FCC compliant [the FCC certifies
the pair together, not the AP and antenna separately.]

- The Cisco devices are extensively documented, and there is a
real support apparatus behind them. A non-trivial part of what you are
paying extra for is carrying part of the cost of the support team.
Especially if you pay for a support contract, then the Cisco site is
amazingly extensive, including tutorials, example configurations,
user guides, command references, and so on. The Linksys documentation,
on the other hand, is relatively basic, and doesn't even -mention-
how to use some of the boxes that are clearly there in the screen
snapshots.

- Did I mention the support?? If you're putting this into a business
network where it is important that it be up, then if you get a
24x7 support contract and you open an online case at 02:00 in the morning,
you *will* get a call back within a short time. Cisco's Technical
Assistance Centre works in shifts from all over the world; I've
received callbacks from Australia, UK, eastern US, and western US.
Now, the cost of that support contract might be more than the cost
of buying the Linksys outright, but if you are installing into a
business, an hour downtime costs the company a lot more than the
support contract.

- If you start to get serious about putting APs into businesses,
Cisco has a device (which is expensive) that makes controlling security
and interference a lot easier. I haven't tried that yet, as I don't
have the budget for it.

You forgot a big difference.

One of the features found in Cisco 350 hardware, that's rarely found
in cheaper boxes is SNMP (simple network management protocol). This
allows me to use standard management software to both remotely
configure and monitor performance, connections, traffic, and errors.
There's nothing like a pretty graph showing traffic and usage
patterns. When something goes wrong, it always shows up as a change
in the graphs. Real SNMP (with supplied MIB's) is, in my never humble
opinion, what separates the quality hardware from the toys.

Does the LinkSys alternative firmware (Sveasoft, HyperWRT, etc.) have
SNMP support?

I think they should, since the firmware is Linux based ...

Thanks.

I have no idea and no experience. There are too many variations for
me to track. Google returns some interesting URL's for "wrt54g snmp"
but I don't wanna track them. Wifi-box lists SNMP support so I guess
it has been done.

One of the problems to watch out for is access to vendor specific
registers at the MAC level. ANS.1 statistics are fairly easy to
impliment in a Linux based system. Digging out statistics from the
vendor specific (radio) hardware registers can be done by digging
though the proc filesystem. However, without a MIB file to organize
the results, it's fairly useless to the management software. Google
didn't find much with "wrt54g MIB" so the level of support may be
lacking.

Please note that some of the (relatively) cheaper access points do
support SNMP.

Best reason to buy Cisco is the quality. I manage a netowrk with around
100 access points and bridges. Have had three failures in the last year
and all happened at the same time due to a power surge on a circuit
that was supposed to be protected.

Other features not mentioned include support for VLANS, using multiple
SSID's on the same access point (up to 16), If using the above two
settings then each SSID can use different WEP keys.

Too many features to list. BTW the power ouput for the 350 series is up
to 100 mwatts and is adjustable down to 1 mwatt. The receivers on the
Cisco are also better than most and this increases the range and
performance.

You can get most of that in a D-link WAP... and you don't need the support
'cos they just work. They have LEAP as well as WAP and the other security
stuff (802.1x). No doubt they are more limiting in MAC's... but if thats an
issue you can buy 4, get 4 times the throughput and 4 times the MAC
handling. If you are talking US$ then they should be <= $80.

:'cos they just work.

D-Link might "just work" for the few situations -you- have tried, but I
have gone through hundreds of postings and web sites about people's
experiences, and the conclusion I came to was that "If D-Link works for
you, it will perform acceptably well, but if it doesn't, you will
probably *never* be able to figure out what's wrong with it and the
support will likely be somewhere between clueless and actively harmful
to your system and networks."

D-Link is, as best I can tell, a consumer class device: you
can buy it and try it out, but if it doesn't work for you in short
order, then *get rid of it* because it'll just end up wasting your time.
It's not a device to put into a business where an hour's downtime might
cost the company several thousand dollars. Cisco might be expensive,
especially their 1200 dual-radio series, but if you call in with
a "network down" problem, then within a matter of hours, you will have
someone digging through the code to solve your problem.

It's a business decision: if your network is such that you can
risk spending days or weeks off and on trying to figure out what's
wrong with your wireless connections, and can afford to try out a few
different low-end models and vendors, then and you have a lot of
patience with trouble-ticket takers who don't have much clue about
how the product works, then you can afford to work with D-Link and
other such consumer devices. But if time is money to you, and you need
the kind of support that drags a manufacturer's technician on-site
until midnight one evening, then you have to play in the big leagues.

:stuff (802.1x). No doubt they are more limiting in MAC's... but if thats an
:issue you can buy 4, get 4 times the throughput and 4 times the MAC

If you are briding between two networks and the MAC table
fills up on one of the devices, it is going to fill up on the other
devices too, except now because you are working with multiple devices
you have to worry about spanning tree hastles and about the different
channels interfering with each other and the different AP's interfering
with the AP's you've installed for the floor below and the wing
across from you.


Anecdote: a few years ago, when we were making the transition to
100BaseT from 10BaseT, a 24 port 10/100 switch from Nortel cost about
$5000, and a 24 port switch from SMC cost about $1000. We did the
math, said "The SMC can't possibly be 5 times as bad", and so went
with the SMC, trying one at first, with visions of saving literally
tens of thousands of dollars when we went to upgrade all our switches.

And everything was fine with the SMC at first, until one day we
realized that some of the devices couldn't reach each other, and by
experimentation realized that all the 10 Mb devices could see each
other, and all the 100 Mb devices could see each other, but the 10 and
100 couldn't talk. "Oh," SMC said after we'd already spent several days
trying to figure out what was going on, "You have to buy a $1200
software license to enable that feature. You missed the fine print in
the advertisements." Well, $2200 was still a lot less expensive than
$5000, so we paid up, and kept going, and everything seemed to be
going fine.

But I noticed little problems here and there whose only common element
was the SMC, and although there was never anything as gauche as
complete port failures, over the next several months, I underwent "The
Death of 1000 Cuts", trying to track down why people sometimes could
not get to the mail server, and having no joy. Eventually I tired of
the unproductive late nights, convinced my boss that paying me overtime
to track the issues was not a good use of my salary or my mental
energies, and we got in the $5000 Nortel switch. And Bingo! the
problems disappeared, and the error rates I could measure fell by a
factor of 100 and I was able to do remote remote management instead of
having to drop in our network probe inline and hope for the best.

It would have been better if the SMC device had been widely faulty:
then it would have been obvious that it needed to be torn out. But
because it mostly worked, I lost a lot of nights trying to figure
out where on our network the problems were and what could be done
to fix them. What did other users have to say? "The SMC works
great for me!"

In our production network, the SMC proved to be a false economy -- and
there wasn't anything in the technical specs that would have allowed
us to know that. We had to live it and get burned for ourselves.


Now these days I'm about to have to fight that fight all over again:
unmanaged 5-port gigabit switches are ~$100 and quality 24 port
gigabit switches are ~$3000. ~$3000 is enough to pay a postdoc for
a couple of months, whereas it does't cost the researchers anything
if -I- have to suffer through long nights trying to figure out what's
going on. It doesn't cost -them- anything if I barely get to see my
spouse during the week, and it doesn't cost -them- anything if I
start burning out again. Sometimes a buck is just a buck, and
sometimes it isn't. When it comes to networking equipment in a
production environment, the -real- cost difference between
consumer equipment and professional equipment is huge, and it's the
consumer equipment that is the poorer value by far.

I have heard some reports/grumbling/warnings that the radios
on the Ciscos tend to fail "early" or "earlier than expected"
(whatever that means). I am not sure what the failure modes are,
or what times-to-failure people have observed, but I get the
impression that the radios tend to fail after their
one-year warranty has expired but not significantly longer
(presumably to satisfy Murphy's Law).
That is, they do not last as long as what you would expect
given their cost and supposed quality.

Is this true? Is their lower-than-expected lifetime due to their
higher-than-usual transmit power? Would running them at lower
than 100 mW, or switching them off after work or on weekends
(where possible) instead of keeping them running 24/7,
prolong their lifetime?

As far as the receivers being "better", in my limited experience
with a handful of Cisco 350 APs and workgroup bridges,
they were unusable in the middle channels (3-4 to 8-9).
Their built-in "spectrum analyzer" should almost 100%
utilization in the middle channels even if the particular
AP under test was the only unit powered on (residential
environment with widely spaced houses) and an Avcom
spectrum analyzer did not show anything happening on
the entire 2.4 GHz band.

Other non-Cisco APs had no problem using all eleven channels.
I could not understand why the Ciscos thought the
middle channels were almost 100% busy, and could only work on
channels 1-2 or 10-11.

slightly off topic - but the 350 is either obsolete, or scheduled to go out
of manufacture.

here is note giving dates for end of life in 2003 - not sure if it is for
the entire 350 range, and you didnt give the model no#
http://www.cisco.com/en/US/products/hw/wireless/ps458/p...

the notes mention s/w support until oct 2004, unless you have a support
contract, when they support until 2008 - but the contract needs to start at
latest in oct 2004 - which may be why they have started to appear as 2nd
hand boxes.

if you want the equivalent current product, then look at the aironet 1100s -
list starts at $600 / box....
