Gigabit Network

Threaded View
Dear All,

I'm deciding to take the plung of upgrading my network to gigabit (or is it
gigabyte)... anyways...I've come to the conclusion that there arn't very
many ADSL/Routers that have gigabit support just yet, we'll not in the home
users resonably price range (and in the UK)..

I was wondering if it is just me and my searches or are they not really
taken of the ground yet....I've search various places, Dabs, Amazon, Ebuyer,
RLSupplies and google itself.....I'm able to obtain Cat6 Cables, Gigabits
(or bytes) NIC Cards, Switchers and plain ole routers, but not with a ADSL
modem built in? (Seen some with DSL and Cable modems, but not ADSL)

Does anybody else know of any that are floating around, ideally I would like
NetGear as I've heard good things about them, the 3 routers/adsl I've had
keep failing and need a reset (on/off) as I download a lot of stuff and I
think they can't handle the transmissions...

Just wondering if anybody has any advice for me, before I take the plunge...

It's very unlikely that your ADSL will deliver anything near gigabit data
rates, so just buy a gigabit switch and nics and patch the switch into your
router/modem.  You will have faster data transfer between computers on your
network, same performance as now to/from the internet.  Your gigabit net
will likely run considerably slower than 1 gigabit/sec due to throttling
by the weak link (probably hard drive performance).  Even so, it will be
significantly faster than 100 mb/s.

If you buy NetGear stuff, be warned that Parago handles their rebates and
your chances of ever getting your check are extremely low.

   Don't know about in the UK, but in the US; 24Mbps for
a DSL modem would be exceptional performance for a DSL
service provider.  ( You will always see the words "up to" in
front of the 24Mbps claim.)

    I've been running a Gigabit LAN for some time now and
have had no problems.   I kept my Linksys BEFSR41 router
connected to my ADSL Modem, but connect everything
through an 8 port gigabit switch. That includes a Buffalo
TeraStation NAS.  Three PCs and the NAS all function
at gigabit network speeds.  One of the PCs functions as
a HTPC (Home Theater PC) and plays HD AVC/H.264
.mp4 files directly off the NAS.

  I'm using an SMC Networks SMC8508T that provides
for Jumbo packets and full duplex operation.  It is Auto
MDI/MDIX on all ports so it's super easy to setup.
Don't know what they go for now, but they were a real
good buy when I got mine.

AFAIK, no ADSL can approach 100Mb, so there is no real
reason to spend a lot on a all-in-one router with gigabit
WAN port.  Get the router you find most cost effective with
the features you need, including at least 100Mb WAN port
(some very old models only have 10Mb, which is too slow for
some brandband, though perhaps fast enough for many
entry-level ADSL services, but regardless of this, the newer
models with 100Mb WAN port are not any more expensive so
there's no reason to not have at least 100Mb WAN port).

As for the gigabit ethernet on your LAN, buy a gigabit
switch with the number of ports you need, or if it makes
wiring your residence easier, buy two or more gigabit
switches.  They are now affordable enough that it is cheaper
and less hassle to just buy another switch or two than to
try to find the perfect all-in-one device or to take
exceptional measure to string more ethernet cables than
needed in odd places in a pre-existing, finished home.

Keep in mind that a brand means very little.  Netgear might
be fine, but hearing about certain models tells you little
to nothing about a different model.  For example their
switches are fairly cheap and run hot because they couldn't
even spend the 50 cents to put a heatsink on some of them
(GS60(n)) version for example.

IMO, the first decision to make is whether you want the
router to include wifi functionality.  It is little to no
extra cost these days, at least in the US there are ample
sales and rebates to make the cost no higher, often even
lower if a router has wifi functionality.  The next step is
deciding whether to invest in newer 802.11n or stick with
the legacy 802.11g.  Google searching can find the
differences, but also an "n" device will be a newer
generation which might be better or worse for other
differences... since as mentioned above you can't take one
or several models from a particula brand as an assumption
their next product will be the same, better, or worse
quality.  Best is to seek reviews of the particular model
you are considering, without regard to manufacturer.

When a router works again after a reset, it is hardware or
firmware so you would attack both angles.  If you find your
router needs reset often, odds are high one of two things
might help:

1)  Update the firmware.  Some bugs significant to your use
might be fixed.

2)  Do more to keep it running cooler.  There are
substantial numbers of people running these newer consumer
grade passively cooled routers who find the tiny slits in
the cases and the heatsinkless network processors just don't
stay cool enough.  One user may have it work fine, but given
a different location, different ambient temp, higher network
load, instability can surface.   Over a period of time
running hot, a router may also degrade the capacitors onto
the point where they are not sufficient anymore.  This would
typically be seen with a router which ran ok when new but
given same ambient environment and same use, later failed to
remain as stable as it once did.  Routers are like all
consumer computing equipment but perhaps even moreso,
subject to capacitor failures over time due to their passive
cooling and more recent plunge in construction costs to
remain competitive in an market where routers sometimes sell
for under $10 after a rebate.

Re: Gigabit Network

Thank you all for the advice...

I'll stick with my exsisting Router, and upgrade everything else....I also
look into moving my router from its hidden place behind my monitor up to the
top of my pc cabinet to aid with the cooling....

At the moment, I'm using a LinkSys router (with ADSL built in) connected to
a 4 port switch, with a Wireless Access Point connected to that, along with
my 3 other machines....

(I think I was maybe leading people up the wrong way, I was only expecting
the WAN ports on the required new router to be gigabit, not expecting it to
make my internet to be any faster)

So, I'll be upgrading my NIC's on 2 machines, new CAT cables and a gigabit

I'm guessing it is worth investing in a 8 port switch now, rather than
buying one 4 port, and another if needed later, because I'm losing a
connection point connecting it to the next switch? two 4 ports only have 6
free ports, as 2 connect between themselves, am I right?

Yes, two 4 port switches would only have 6 ports remaining,
but the real question is whether you want to string all the
cables to this one central location or if it would be easier
to run one cable to the 2nd switch and then cable routing
would be more convenient to this 2nd location from the
PCs... and of course if you only had 6 systems or other
ethernet devices, though it is only a matter of adding
another switch later.

On the other hand, an 8 port switch can also be upgraded
with a 2nd switch later... depends on how many systems you
forsee and their locations.
