Using Macbook as an Ethernet Port

I have a Blu-Ray player that is able to stream Netflix, etc., but it did not come with wifi (and it costs an extra $100 to get the wireless card). It does have an ethernet port, however, so I was wondering if there is a way to configure my MacBook to provide internet access to my Blu-Ray player through the ethernet port. Anyone else try to do this? Thanks.

if the ethernet settings (such as ip adress, subnet mask,) are changeable in the blueray players menu then this will help. it will be the same if you had an xbox to share you connection to.

Using both Dual Gigabit Ethernet Ports

Using both Dual Gigabit Ethernet Ports
If I plugged both of my ethernet ports into my LAN switch, that would double the bandwidth to and from my machine. A switch does not used shared bandwidth like a hub does. I realize that it won't speed up any of the other devices that are plugged into the switch. Regardless, I would have the capacity for double the bandwidth to my machine.
All LAN cables are CAT6 and the switch is 10/100/1000.
The question is, would Mac OS X 10.4.7 utilize both ports (soft of the way it uses multiple processors)?

It's easy to try... it's call "Link Aggregation"...
http://docs.info.apple.com/article.html?artnum=304120
You get to it by Network>Show>Network Port Configurations>New then Port in the popup, then you schould see Port Aggregation. Selt the two ports you wish to combine.

RT: How do I use two independent Ethernet ports?

I have looked around at the forums and seems like no one has had a real solid answer or example on how to use 2 Ethernet ports with RT.
Right now I have two connections configured on the RT:
Primary Connection:
IP:192.168.2.181
Subnet mask: 255.255.255.0
Gateway: 192.168.1.1
DNS Server: 192.168.1.1
Secondary Connection:
IP:192.168.1.180
Subnet mask: 255.255.255.0
Gateway: 192.168.1.1
DNS Server: 192.168.1.1
After using this initial setup, I made a RT project where I used 'UDP Open' for both 192.168.2.181 and 192.168.1.180, and had them both read and write in a sequence (Read and Write for the 2.181 connection, then Read/Write for 1.180).
The computer I'm using to send the data is connected to a switch, which in turn is connected to the RT. Both the RT and my host computer have 2 ports, one of them with ports configured to be 192.168.2.x and 192.168.1.x
Using this configuration I get some weird results:
If I send a packet to 192.168.2.181, I receive it from the UDP Receive vi that has an input connection from my UDP Open assigned to 1.180. I also receive the data the same way when sending packets to 1.180 (as expected). Basicly, no matter what IP I'm sending it to on the RT, the data from either packet will arrive from the same location/vi.
Why is this? Is there anyway to fix this? Did I not configure something correctly?
Does anyone have an example of dual Ethernet ports actually working with LabView RT?
I tried checking out "KnowledgeBase 3VQ6278T: Can I Use Multiple Network Adapters in a PXI or Desktop Real-Time System?", but after following the link to the page, I get:
"Error You are not authorized to view this document". Can any NI people look into this?
Having to make two IPs with different subnet masks obviously just makes things unnecessarily complicated. Can anyone tell me why LabView/NI did this? I know for a fact this isn't a limitation in hardware.
Any help would be greatly appreciated, thanks!

Hey Weizbox.
Sorry to hear you're having such a difficult time using multiple ethernet devices with RT.
Let me go ahead and get the easy stuff out of the way, the link you
have is dead because it's archived (and thus removed forever) though
unfortunately the link on ni.com wasn't corrected to point to the
following resource, which the KB was a word-for-word duplication of
(which is supposedly why it was removed):
http://zone.ni.com/reference/en-XX/help/370622C-01/lvrthelp/configuringdual/
Unfortunately, though, it's much less useful than it sounds.
Before you start feeling like a woodpecker in a petrified forest, lemme
fill you in on why the requirement is there for the two ethernet NICs
to be on seperate subnets. Simple enough, it has to do with the
network stack on both of the operating systems used for LabVIEW
Real-Time - however, the same falls true for even Windows (without
using fancy vendor-specific drivers), so let's not be too hasty.
Neither PharLap ETS nor VxWorks, the two OS's used under the hood,
support redundant network ports. Because of this, if you give two (or
more in the case of PXI and RT Desktop) ethernet devices IP addresses
on the same subnet the routing tables in the network stack get horribly
confused and literally cannot resolve the proper adapter, which either
brings down the ethernet on the entire system or makes it such that one
or more network adapters becomes useless and one adapter takes over all
network traffic (there's no way to predict which adapter that will be,
nor can you control it based on what's plugged in and what's not). On
Windows this is handled by bridging the adapters, but RT does not yet
support bridging (that opens a whole nother can of worms). Long story
short, you still wouldn't be able to give both NICs individual IP
addresses on the same subnet.
Let's take that even one more step. You cannot simply just assign both
ethernet NICs different IP addresses on "virtual" subnets, you actually
need to put both NICs on literally different subnets for the network
routing to actually work. Multiple ethernet devices for LabVIEW RT
were designed with the following mantra in mind - "The FIRST ethernet
device is designed for a TCP/IP network, the SECOND and SUBSEQUENT
ethernet device is designed for OTHER protocol uses." By "OTHER
protocol uses" I mean the second NIC should be used for RT
Deterministic Ethernet (PXI, RT Desktop, et. al.), direct connections
with other targets, and 3rd party or custom ethernet protocols.
Now, realistically, we can't expect users to not use the second NIC for
TCP/IP use, nor should we. However, if you ARE going to use TCP/IP on
the second NIC, you should only use the second NIC for connecting to an
unroutable network in the eyes of the first NIC. So, for instance, the
FIRST NIC can have an IP address of 10.0.62.128, but the SECOND NIC
would need to have an IP address on 192.168.100.23 - and the
10.0.62.128 should not be able to route a TCP packet to the 192.168.x.x
network, and vice versa. In your example I noticed that both networks
used the same Gateway - unless your Gateway is configured to identify
and seperate the two networks, it's not going to end well, and you
shouldn't expect to be able to send data from one NIC to the other NIC
(at least with what you know now). To reiterate, using multiple NICs
using TCP/IP should only be done in cases where you've got (n-1)
isolated subnets, where n is the number of NICs you have using TCP/IP.
A classic example of this is a command-based measurement environment;
the RT system uses the FIRST NIC to talk to a TCP/IP network, in order
to transfer data or provide status to a network, and the second NIC is
connected to a TCP/IP network designed specifically for measurement or
control, where one node sends commands to a single or multiple nodes on
the network at once to perform tasks (like "Take a Measurement", "Stop
a motor", "Bake me a Pie", etc...). The isolated TCP/IP subnet is free
from "random" TCP/IP traffic (especially system announcement
broadcasts) and can have whatever topology/configuration it wants. The
dual networking allows the RT system to work/communicate/perform on
both networks.
I hope this helps shed some light on your situation.
Cheers!

How do you make use of the 2nd Ethernet port on the Mac Pro?

My Mac Pro's ethernet port connects it to the local network and the internet.
Under what circumstances would I make use of the 2nd port?
Are there any settings I'd have to set up in system preferences to make sure one is used for some things while the other is used for different things?
I'm asking because we might be making some changes to our network. We have a printer with a Fiery RIP and I'm pretty much the only one who prints to it. I was wondering if we could/should set up a direct, dedicated connection so that network traffic won't bog down print jobs.

The main use for that port today is to create a subnetwork for Internet Sharing. Software inside the Mac can act as a Router and provides new DHCP Addresses for the subnetwork. In general, the devices on the subnetwork would be inaccessible from anywhere else, due to Network Address Translation.
If you are concerned about heavy network traffic, consider upgrading your Switches (not Routers) to Gigabit Ethernet speeds and using Jumbo frames. (Routers are not involved in peer-to-peer transfers such as Printing when no Address Translation is involved.)
If you have an Industrial Router, you can combine the two Ethernet ports into one composite link for faster-than-Gigabit effective speeds, but it requires a special Router not generally available.

Using more than one Ethernet port

So I just brought myself another pair of TP link wifi adapters as I already had some, but the ones I had only had 1 port and these have 3. So I set it all up and try to use 2 ethernet ports as I want to use my xbox one and Laptop through these adapters. So when i set it up and pluged the ethernet cables into the router the broadband light on the hub goes orange and the broadband is lost unitl i take out one of the ethernet cables and reset the hub it works fine with just one.
I just really want to know why i cant have more than one ethernet cable plugged into the hub.
Solved!
Go to Solution.

You can only connect one broadband extender to the home hub. This must be designated as the Access Point. All the rest need to be slaved to that Access Point. These need to be individually "paired" to the AP one connected to the home hub.
You can still use the other ports on the home hub for direct Ethernet connections.
If you try and connect more than one extender to a home hub Ethernet port, you will create a loopback, which will crash the home hub.

Using 2nd Built-In Ethernet port for internet access?

Hello,
I have a Quad-G5 running 10.4.8. In its current configuration, all its network communications, including web access, go over the active ethernet port (Built-in 1).
Does anyone know how I could use the second built-in port for internet access only? I'd like to route local traffic over the first port, but go "out" over the second.
The machine is on a corporate network, and proxy access is slowwww. I have the ability to use a direct connect to the internet, but still need to be connected locally. Any thoughts? Many thanks . . . JD

Easy. Go to System Preferences > Network > Network Port Configurations and drag the port connected to the internet to the top, so that it has priority over the port connected to your LAN. This prevents DNS time-out when loading a website, but still allows LAN traffic over the other port because that traffic is most likely going to use ARP rather than DNS. For good measure, you can add your company's domain (such as "my_company.lan") to System Preferences > Network > Internal_Ethernet > TCP/IP > Search Domains.

Macbook Pro 13' ethernet port is missing

Hello, I just noticed this today... and I'm not sure when it happened but my ethernet port is missing, I will provide a picture.
What I see is a black rubber, a triangle with a circle in the middle. The ethernet cable won't connect into it.
What should I do? Thank you.

That port on the far left is your Ethernet port - followed, from left to right, a FireWire port and a Thunderbolt port.
The Ethernet port does look a little beat up, however, so I'm not surprised that you can't connect a cable to it.
It almost looks as if there's a broken Ethernet plug in the port (hard to tell from the photo).

Is it possible to use the built-in Ethernet port in the RE1000 to Minimize Decreasing throughput

Kindly
Is it possible to use the built-in Fast Ethernet (10/100 Mbps) port to extend the network with an Ethernet cable without placing the extender in an area where you still have at signal ?
because i dont want to decrease the wireless through-put by 50 % .
I would like to Expand the network network by running an Ethernet cable from an RE4200(Basement floor ) router to the end of the RE1000 built-in Fast Ethernet (10/100 Mbps) port in the second floor..

The Linksys RE1000 Wireless-N Range Extender includes a built-in Fast Ethernet (10/100 Mbps) port, which works as a wireless bridge to instantly connect any wired Ethernet device to your network. To ensure the proper configuration of the range extender, you need to know the wireless settings of your router or access point. These settings are:
• SSID
• Wireless Channel
• Wireless Security and Network Key
Here is the link for manually configuring a range extender: http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=206954591ff54e36884bb4636fcfd3d9_Manually_configur...
Once your range extender gets sync with your router you can make the RE1000 as a Bridge...

How to connect to TC, new MacBooks have no Ethernet ports

How to setup Time Capsule to use wifi and 2 ethernet ports

Hi, I hope someone can help with this issue as I've been searching for an answer without success. Basically, can a Time Capsule (1st gen) connected to a modem create a wireless network, as well as connect to an ethernet powerline adapter, as well as connect to an iMac by ethernet?
My original setup was as follows:
modem > time capsule (which creates a wireless network) > iMac
I bought an AirPort Express to use in another room. It was extending the TC wifi network, but the speeds weren't great so I've got a pair of powerline ethernet adapters. I wanted to add those into my current setup so that the Express can create a wireless network.
Anyway, before I can get to that stage, I'm having issues with the TC. I want to achieve the setup as follows:
modem > time capsule (which creates a wireless network) > powerline adapter 1 * > powerline adapter 2 > airport express
* But as well as connecting an ethernet cable to powerline adapter 1, also connect one from TC to my iMac.
When I tried connecting an ethernet cable to the TC in my original setup, the iMac lost connection to the internet. I've managed to get the following setup to work:
modem > time capsule (which creates a wireless network) > powerline adapter 1 > powerline adapter 2 > imac
But to achieve the setup I want, would require me to buy another powerline adapter (for the Express), and it seems silly to have to use a powerline adapter for my iMac when it is right next to the TC.
Any help would be appreciated.

When I tried connecting an ethernet cable to the TC in my original setup, the iMac lost connection to the internet. I've managed to get the following setup to work:
What you are attempting should work fine. The TC should be able to manage multiple ethernet connections as well as the wireless.
Investigate what is happening when you plug ethernet into the TC from the imac.
Please try it.. turn off wireless in the imac to ensure ethernet is the only connection.
But I would recommend you shut off the whole network at that point. Restart everything in order.. modem .. TC.. EOPs.. Express.. clients.. with 2min gap between them.
Now look at the imac and check the network preferences.. did it pick up the correct IP from the TC? It should have router (gateway) and DNS all correct using dhcp.. if not check the connectivity light on the TC.. does it come on when you plug in the ethernet cord?
Open a terminal on the mac and ping the TC address. does it respond?
Give a few screen shots of how the TC is setup.. bridge, router and what IP it is running. Even just the summary page.

How easy is it to plug a windows laptop into the ethernet port of a Time Capsule and for it to get an internet connection?

I use Time Capsule to distrubute wifi thoughout my home. I have an office laptop (windows) that my company's IT dept won't install a wireless card in (for security reasons????). Can I get an intenet connection to the laptop if I connect it to an ethernet port on the back of the TC?

Can I get an intenet connection to the laptop if I connect it to an ethernet port on the back of the TC?
If you can get an Internet connection when you test using your iMac's Ethernet port, then you know that the Ethernet port is working on the TC and the Ethernet cable is also working.
You should be able to get a connection on any other computer in the same way.
If you cannot get an Internet connection on the PC with the same hook up, then you will need to do some troubleshooting on the PC....or call the IT guys at the company to find out what type of block they may have on the PC.

Poor network performance on wired ethernet port and airport

I'm using Leopard 10.5.1 on a home network comprised of a new, fully up-to-date (firmware wise) D-link wireless router and a couple ethernet hubs. I initially had problems because of old router firmware, but buying the new router and making sure firmware was up-to-date seems to have solved the connection problems. What I now experience is that whichever network cennection I am using, wireless or wired ethernet port, will slow down so slow that it's impossible to get any web content, upload files to my local server, or sent emails with any kind of attachment. Turning off the connection I am using, either wired ethernet or airport, and switching to the other solves the problem for a short time, usually a couple days or so. Then that connection with slow down and I have to switch back - again solving the problem. So to keep my network connection alive, I have to keep switching back and forth between the wired ethernet and the airport connection.
The rest of my network consists of several Windows machines including a Windows 2000 server. None of these devices ever have any problems with network access.
I've tried playing with the advanced settings with no luck. Does anyone know of a specific setting that might be the culprit?

Hi ,
Maybe you can try to disable checksum offloading and jumbo frames on the Physical NIC (ESX platform) to check result .

HH3 ethernet ports.?

I use 1Gb ethernet [cat6] on my network and am having Infinity installed in a couple of weeks.
Does the HH3 have Gigabit ethernet ports.?
I also have a gigabit belkin router that uses gigabit ports,is it allowed if I send all data to it from the HH3 intergrated router if I need to.?
Solved!
Go to Solution.

At this time I use a VM modem with an ethernet cable plugged into the WAN port of my belkin.
And my network is using the 4 LAN ethernet ports.
The HH3 is a modem and router and has 1 Gigabit LAN port as you state,but does it also have a WAN port that I could use to plug into my belkin,like I am doing now with the VM modem.?
If not then I would have to plug the HH3s gigabit LAN into the WAN port of my belkin and then config the router in the HH3 to send all data to the belkin,bypassing the HH3s router.?
Hope this makes sence as its hard to explain in text.

Ethernet port on MacBook Pro only works under certain conditions

Since I've purchased my MacBook Pro over two years ago now with an initial installment of OSX 10.5.x, I've had a small annoyance if while the OS was up and running and my physical network interface was disconnected and reconnected, a connection could not be reestablished until I shutdown, restart or put my Mac to sleep and woke it back up with the cable connected to the ethernet port. It would randomly work as it should if I connected and disconnected it over and over again until the machine decided I've stimulated it enough to allow me to use it. But it's recently become a real annoyance for me since the tab on my longest ethernet cable broke and it no longer locks it in place and now the slightest budge displaces the cable and I have to put the laptop to sleep often to reestablish a connection.
I would opt to Wi-Fi, but my Mac (surprise, surprise) out of 4 other laptops is the only one whose signal is too weak to use where I use them most. I've reinstalled the OS once to no avail months ago and the problem persisted after downgrading to Slowleopard a day after it's release.
Anyone have any ideas what may be going on? Any help would be appreciated. Thanks.

Hello DavidJoyce
Best thing to do is to buy a new Cat 6 Ethernet cable.
