OT DEL and modern computers

I've heard/read that many modern computers don't have ethernet connections.
Anyone know if this is true? If so, how does one use DSL to get on-line?

If a combo ADSL modem/router also has Wifi, then a Wifi
equipped PC would work with it.

You can always add a Wifi card to a full-sized PC, using
an expansion slot. You can add Ethernet cards too, but
the choices available aren't what they used to be. At
one time, you could go into Best Buy and they'd have
three or four SKUs to choose from. Today, you might
not find any GbE Ethernet cards worth buying.

Some of the smaller motherboards use built-in WIfi. This one has both
Wifi and GbE Ethernet.

Max LAN Speed
10/100/1000Mbps

Wifi
Intel 802.11ac WiFi Module (Free Bundle)
Supports IEEE 802.11a/b/g/n/ac
Supports Dual-Band (2.4/5 GHz)
Supports high speed wireless connections up to 867Mbps
2 antennas to support 2 (Transmit) x 2 (Receive) diversity technology

The Ethernet has a "goodput" of 112MB/sec. The Wifi delivers 108MB/sec
thruput, and the goodput might be in the 90's or so. But that's under
some sort of ideal conditions. Real-world Wifi seldom gets to even
half the supposed rate. The GbE Ethernet is simply better.

The fun comes in, when you look for a combo ADSL modem/router,
and expect to see dual-band 802.11ac Wifi on it. Especially the
ISP rentals, they don't always have the most current networking
standards. In some cases, they're shockingly bad. Not all ISPs
are clueless, but some of the larger ones certainly are.

*******

The best Wifi available, runs in the 60GHz band, and has a thruput
of around 700MB/sec (as long as you stay in line of sight,
and are in the same room). The best Ethernet is 10GbE with
a thruput of 1250MB/sec, and costs around $100 a unit today.
They used to be $500 for a card, somewhere between say
$350 and $500, but new entrants to the market are shaking
things up.

On older systems, the problem is finding a slot for it.
(Some systems might only have a good video card slot,
and not a lot of x4 or larger slots for other devices.)

I haven't seen any benchmarks that say the CPU has an
easy time pumping stuff at that rate.

Or a wifi adapter to a USB slot: new mobos may not have an ethernet
socket (though I've not seen one yet), but they have USB sockets coming
out of their ears. In UK, a single-band USB wifi adapter costs from
about 2 or 3 quid, a dual 8 to 10. (That's ones with a removable aerial;
ones without are cheaper.)

Also look at what speed you're getting from your ISP to the outside
world; the only reason for worrying about a connection (ethernet _or_
wifi) to your _router_ that's _much_ faster than your connection to the
outside world, is if you do a lot of large file transfers between
computers on your own network. (As may be the case, if you route HD
video round your house via your router.) But unless you do this, there's
no need to be sold mega-speed internal routing - it won't speed your
downloads!

The reason for wanting whizzy Wifi standards, is so
LAN to LAN transfers in your computer room, happen at
a decent speed.

If I'm transferring a 40GB VM image from 192.168.0.1 to
192.168.0.2, I want wire speed from that. As much as the
tech can manage (at a reasonable price).

If I'm doing backup from my SSD-only computer, to the
4TB backup HDD inside computer #2, I want the
wire speed to match the destination disk speed. (As the
destination rotating hard drive might be the limiting
factor.)

It wouldn't surprise me to find an ISP selling a
GbE fiber internet connection, with a router running
802.11N as an example. Some people in the group, do have
actual decent Internet speeds, and are paying $100+ a month
to get them. And they wouldn't want to be throttled by an
inadvertent choice of that sort.

Note that, even if the router was 802.11ac, and the computer
had an old 802.11n 1x1 (Edimax $10 dongle) in it, then the
802.11n determines the rate, and the ac end "falls back"
to match.

My experience is, lots and lots of people don't realize
just how many hurdles they have to jump, to get the
actual potential from Wifi. Ethernet is a lot easier
to get right. The way Wifi is done, it's mostly false
advertising - for example, an apartment dweller will
*never* see the rates listed on the tin, as there will
be a ton of 802.11g to cause the channel width to stay
at 20MHz.

That's my reason too, but with a different emphasis: there's little
point in buying ultrafast home routing (wifi or otherwise) if you're a
sole user (and one who backs up to something directly connected),
_unless_ you have a very fast internet connection. It isn't _false_
advertising as such that bugs me (well, it does, but): it's deception by
omission. In that, ad.s for fast wifi (or ethernet hardware, but the
wifi is pushed more) usually _don't_ mention the fact that it won't
(much) improve your online speed. (I think those who _do_ have a high
online speed - especially if they're paying a lot for it - would be less
affected; it's the ordinary ADSL-over-'phone-line users I'm thinking of,
whose download speed won't be that much affected by having a wifi three
to ten times the speed their ISP is giving them.)

The CenturyLink C1100Z DSL modem (owned by them) evidently has Wi-Fi. An
indicator LED on the front is lit and says Wireless. There is a female
connector on the back that says LAN/WAN. That's all I see that I don't
recognize. Looks like a DSL connector. I thought there'd be an antenna
BNC or whatever connector.

Guesses?

Not as to what the solution to your problems are, but: a lot of routers
that provide wifi don't have an external aerial (much like, I suppose,
most laptops/netbooks, and a lot of USB wifi dongles).

[If it _did_ have an aerial connector, it'd not be BNC - it'd probably
be "F type", little gold-coloured screw one. I don't think the BNC
connector was designed to go as high as 2.4 GHz.]

The WAN connector is in essence, a "convenience" connector.

The documentation says, if you aren't using it as a WAN
function, the Ethernet switch functions as a *five* port
LAN switch. The WAN port is the same as a LAN port, except
the wiring is "rolled" for cases where 100BT equipment
(like a separate broadband modem) might be connected
to the WAN port. The WAN port is a different color, to indicate
that a different cable might be required. For example, if
you wanted to connect a 10/100BT computer to the fifth ("WAN")
port, you might need a rolled cable, with red hood on one end
and blue hood on the other end. If connecting the WAN port
to a 10/100BT broadband modem, a "straight" cable would be
used (because the modem output would have different pinout
than the computer would). When using MDIX capable (mostly
GbE computers), this stuff doesn't matter.

In your case, you would be using the Standalone Operation mode,
where the combo modem/router, does both modem and router function.
You plug in the phone wire, for the first mode of operation.
You can simply use LAN ports and just ignore the WAN port.
If you really needed to connect a fifth computer, you
could play with that port.

Standalone Operation Wifi
/
Phone --- RJ11 --- modem ---- router ---- WAN --- (The arrows used here
---- LAN --- are in the logical sense
---- LAN --- of a direction, as in
---- LAN --- connecting up to five
---- LAN --- of your computers.)

Router Only Wifi
/
//--- RJ11 --- modem ---- router ---- WAN --- Broadband source into here
---- LAN ---
---- LAN ---
---- LAN ---
---- LAN ---

With the router operation, you might take a DOCSIS modem,
and connect it to the WAN port. Then use the box just
as a router, with the modem part disabled by virtue of
not being connected.

That's my best guess. Maybe Char can say more about it.

If you put a Wifi card into a PCI slot on an old PC,
this could take the place of Ethernet and the wired
NIC concept.

This is an example of a universal (3.3V or 5V) PCI card
with Wifi antennas on it and everything :-) This one
is $30. Check the reviews before you buy one, as not
every Wifi design is a "winner". Designs that use separate
bipolar radio chips last longer, but those sorts of
details are "hidden" under that metal hat on the thing.

Some review sites, take the lid off the design, to show
the parts underneath.

https://www.smallnetbuilder.com/wire...dapter-roundup

In this example, the sixteen pin chip on the end, could be
a separate radio chip. We have to rely on the description provided
by the reviewer, as I can't keep up with these things. Notice that
Asus "OEMed" this design, from another (famous) supplier. Edimax
is mainly famous for their $10 Raspberry PI dongle.

https://www.smallnetbuilder.com/imag...ac51_board.jpg

"The ASUS USB-AC51 board marking reveals it's an
Edimax EW-7711AUC in disguise.

The chip to the right of the MediaTek MT7610U is a
Skyworks SKY85702-11 5 GHz front end, which includes a
5 GHz power amplifier.

Note the use of bent-metal antenna vs. printed circuit."

The bent metal antenna, is along the lower edge of that PCB
layout picture. You can see a couple inverted U-shapes in
sheet metal of some sort.

Whether a design is a winner, can be seen in the positive reviews
on Newegg. Or, if you can obtain a picture such as the one
above, you can see whether it separates the MAC portion from
the radio portion, and uses a separate radio chip.

The little sixteen pin chip on that one, is less likely
to "burn out" and get tired after running for three months.

Finding good review ratings on Newegg, is your best summary
of whether a thing is a "winner" or not. As it's not always
possible to get pictures with the lid off.

Also look at what speed you're getting from your ISP to the
outside world
The reason for wanting whizzy Wifi standards, is so
LAN to LAN transfers in your computer room, happen at
a decent speed.

If I'm transferring a 40GB VM image from 192.168.0.1 to
192.168.0.2, I want wire speed from that. As much as the
tech can manage (at a reasonable price).

If I'm doing backup from my SSD-only computer, to the
4TB backup HDD inside computer #2, I want the
wire speed to match the destination disk speed. (As the
destination rotating hard drive might be the limiting
factor.)

It wouldn't surprise me to find an ISP selling a
GbE fiber internet connection, with a router running
802.11N as an example. Some people in the group, do have
actual decent Internet speeds, and are paying $100+ a month
to get them. And they wouldn't want to be throttled by an
inadvertent choice of that sort.

Note that, even if the router was 802.11ac, and the computer
had an old 802.11n 1x1 (Edimax $10 dongle) in it, then the
802.11n determines the rate, and the ac end "falls back"
to match.

My experience is, lots and lots of people don't realize
just how many hurdles they have to jump, to get the
actual potential from Wifi. Ethernet is a lot easier
to get right. The way Wifi is done, it's mostly false
advertising - for example, an apartment dweller will
*never* see the rates listed on the tin, as there will
be a ton of 802.11g to cause the channel width to stay
at 20MHz.

The CenturyLink C1100Z DSL modem (owned by them) evidently has
Wi-Fi. An indicator LED on the front is lit and says Wireless.
There is a female connector on the back that says LAN/WAN. That's
all I see that I don't recognize. Looks like a DSL connector. I
thought there'd be an antenna BNC or whatever connector.

Guesses?

VDSL2 (rj11 phone connector)

300 Mbps 802.11n access point [2.4GHz] 2T x 2R
(must be two internal antennas)

GbE WAN and 4 port GbE Switch (RJ45 connectors)

Looks like wired connections would be the fastest,
when doing computer-to-computer file sharing on the
thing.

To get back to the original question, what about modern computers
without ethernet connectors? I thought to Wi-Fi eliminated this
problem by transmitting the DSL signal to the PC wirelessly. If
there's no ethernet connection, how do you connect this modem's WAN
signal to it?

Perhaps the answer is in your links - haven't had a chance to read
them yet.

WiFi is your LAN connection.
Do you actually have a new PC without the RJ45 connector? I have never
seen one.


I was told this by the salesman in the electronics area at my Walmart.
I'm not serious enough about a new one to look any up on Google.

Good news that it's not a problem.
