Ethernet Port Connection Speed Test

I'm an LV newbie and want to verify that the connection speed between a PC running LV and a listening system is 100Mbps. Can this be done with LV or do I need an Ethernet test (e.g., BERT or similar) to do this. Pinging the other port can't tell me the connection speed to my (little) knowledge.
Solved!
Go to Solution.

Not sure if this is useful or not but you can open the Task Manager and look at the bus utilization on the network devices and their theoretical maximum speed.

E3500 - Cloud Connect Speed test not correct

I’m doing a comparison on my internet speed using various methods and the Cloud Connect Speed Test app.
First thing I noticed is the App gauge only goes to 20Mbps
I have tested various online speed tests and I get a consistent 70 – 90 Mbps.
(I work from home using multiple VoIP lines and have extreme bandwidth requirements so I’ve opted for the higher package)
Why is the Cisco Cloud App showing only 7 – 16 Mps?. The upload is inline.

Two things that I can think of. First is to go into the bios, hit the F9 key to set Setup Defaults, then hit the F10 key to save and exit. This has been known to make a difference on some systems.
Also check to see if you ahve the latest bios version. On that one the latest is 1.40. IF it isn't you might want to try updating it to the latest.
Go to the Product Support Link at the top of this page, enter in your model, then clik on the Download Tab to find the available bios files for that model. The latest is 1.40. DO NOT update the bios from within Windows. Don't do it, don't even think about doing it if you want to use your computer again. When you double click on the download you will be presented with the choice of creating a CD to flash the bios from. USE THIS METHOD. You can use a CD-RW so you don't waste a blank, but even the cost of a regular blank CD is cheap compared to the $100 that most places will charge you to fix a botched bios flash. Make sure that your battery is fully charged, installed, and the AC Adapter is plugged in just in case.
And don't forget to go into the bios and hit the F9 key to set Bios/Setup Defaults then F10 to exit and save just prior to and immediately after updating the bios.

EA2700 download speed - local port connection speed

Hi,
I've recently upgraded my ISP connection to 200Mbs dl and 20Mbs upload.
Using a test (speedtest.net) to determine my connection speed i discovered that the downloadspeed only reached about 75 Mbs , but with the modem directly attached to the computer it reaches almost 190 Mbs , so the problem must be with the EA2700 router.
I've tried everything , upgrading firmware , downgrading firmware , changing the MTU , dissabling IPv6 etc.
I have narrowed the problem down to this: After starting my computer (from the off power) the downloadspeed is 75Mbs (although the status within the routers webinterface says i have both on WLAN and localport 1Gb).
After restarting the router (by the routers webinterface) the speed is 180Mbs.
Seems like i have to start the computer first and then switch on the router (ridiculous i know) , seems like although the portspeed indicates 1Gb i only have a 100 Mb port speed....
Any ideas? or is this just a crappy router?

I suspect that this is a basic internal issue in the router.
I'm a retired networking system administrator and am not unfamiliar with devices that don't work the way the sales force claims -- especially at the upper limits of those claims.
I have only been playing with the EA2700 now for a few days, but am absolutely astounded at how "un-professional" all of the documentation and support information for the device is.
I say "un-professional" meaning -- seriously consumer oriented. No technical specifics. Granted I'm familiar with the "classic interface" on Linksys products and am not particularly enamored of this new web based environment. But that's just my history.
At any rate. I'm fairly certain that you need to try to reach "tier 2" (or maybe higher) tech support on the phone to find out what the actual throughput capabilities of the hardware and software are.
200Mbs is a "new" speed common to FIOS, but not to Cable. The end result being that the probability that new-product testing at that speed is at best, incomplete. And, I suspect it has not been done at all.
While the "chips" may be capable of running at Gig-a-bit speeds, a router's speed is controlled by the internal "routing speed" of the software.
Before I retired, I used to confont this kind of issue routinely in working with Internet2 -- the hardware available "claimed" to be able to do the job, but the on-the-job evaluations proved that it was not capable. But we had to spend a lot of time developing tests to refute manufacturer's (marketing) claims.
It may be the simple fact that the EA2700 (as best I can tell) is now very long in the tooth -- apparently introduced back in April of 2012 -- 3 years ago - an eternity in Networking. That coupled with the fact that the EA2700 is the "entry level" device in Linksys' EA product line.
An interesting review (Review Date April 30, 2012) in PC Magazine: http://www.pcmag.com/article2/0,2817,2403745,00.asp primarily discusses the WiFi side of the router. It hedges its bets on the hardware by saying "We will revisit this router when that software becomes available. Perhaps then the true value of the EA2700 will shine though." (I haven't found that review yet.)

TC ethernet port question

Hello. My apologies if this has been covered before, but I'm having difficulties connecting one of my computers via ethernet to a new 2TB TC. Yesterday I replaced my old TC by copying its configuration file and importing it while setting up the new unit. This seems to work out fine for all the wireless and wired clients except for one, my Mac Pro, which is connected to an ethernet port on the new TC. I can't seem to find a way to diagnose what's gone wrong. Network Preferences recognizes that the ethernet cable is plugged into the Mac, but it has a very different IP address than the other clients and can't connect to the network or the Internet. I suspected either a port on the new TC wasn't working right or something was wrong with the cable itself (though everything was fine before the TC replacement) but after reordering the ethernet port connections and successfully connecting my laptop to the network through the same ethernet cable my Mac Pro was on, I realized all the connections appear to be fine and the problem is likely the Mac Pro.
I eventually connected an old Airport Express to the same cable and was able to bridge the network to the Mac Pro wirelessly, but I'd love to figure this out if there's something I'm doing wrong on the Mac Pro (I'm definitely no networking expert). If it's potentially the built-in ethernet that's the problem I'd like to know that too, before my warranty runs out.
If anyone's got any ideas I'd really be grateful.
thanks,
Paul
I should add I've tried Network Diagnostics and Network Assistant to try a new location, without any luck.

Yesterday I replaced my old TC by copying its configuration file and importing it while setting up the new unit. This seems to work out fine for all the wireless and wired clients except for one, my Mac Pro, which is connected to an ethernet port on the new TC.
Check the connectivity leds come on.. both on the TC and the Mac Pro. although I am not sure if it has connectivity led.
Try forcing the network card to a specific speed.. slower being better.. to test at least. Set to 100mbit full duplex. You do this via the system preferences for that network card.
If you still have the old TC plug the Mac into it.. if it works set it to bridge and plug the new TC into the old one. What happens?
Network Preferences recognizes that the ethernet cable is plugged into the Mac, but it has a very different IP address than the other clients and can't connect to the network or the Internet. I suspected either a port on the new TC wasn't working right or something was wrong with the cable itself (though everything was fine before the TC replacement) but after reordering the ethernet port connections and successfully connecting my laptop to the network through the same ethernet cable my Mac Pro was on, I realized all the connections appear to be fine and the problem is likely the Mac Pro.
Is the address you are getting 169.254.x.x which is a self assigned address and means the ethernet card cannot connect to the TC?? Try using a manual setup as well as the manually assigned speed. If the TC is at default, assign 10.0.1.100 say to the ethernet and 255.255.255.0 with router and dns set to 10.0.1.1 and see if it works.

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.

Ethernet Port Not Working After 10.6.6 Upgrade

Hello! Since upgrading to 10.6.6, I have lost my Ethernet port connectivity. AirPort is working fine.
I have done the following:
-checked ethernet cable
-used System Preferences/Network to check connection and try to create a new one
-used Diagnostic button
-zapped PRAM
-reset SMC
-repaired my disk permissions
-installed the 10.6.6 combo update
-booted in Safe Mode and then restarting
Is anyone aware of an incompatibility with 10.6.6 and the Yukon adapter?
Any suggestions greatly appreciated!

let me reiterate. 27 ' iMac 3.06 GHz Intel Core 2 Duo just updated to 10.6.6 uses AirPort to access the internet. Set up to share it's internet connection via ethernet with PPC Dual 2.3 G5 running 10.5.8. Up until the 10.6.6 update things were fine. After updating the iMac's OS, the PPC lost it's internet connection. On the PPC's network System Prefs, the built in ethernet is connected and green. The iMac is in the finder under Shared. On the iMac, the PPC is in the finder under Shared and in Network settings the ethernet connection has a self-assigned IP with a yellow light. I have reset and rebooted all settings and devises on the network with no resolve.

Conflict with ethernet Internet connection

Since the last firmware update, a weird conflict has emerged. When a Thunderbolt cable is plugged in so that my MacBook Pro is connected to a display, the Internet connection goes down. I obtain the Internet through an ethernet cable connected to the mains electricity circuit.
When I start up in the morning, the Internet and the display work for about five minutes, and then the Internet fails. It comes back every time I pull the thunderbolt cable out. It disappears when I put it back in. Network Diagnostics says I get as far as the network, but not to the ISP.
This is very frustrating. Any ideas anyone? I have just updated to version 10.8.3, but this has not fixed the problem.

I'm not sure what you mean by...
I obtain the Internet through an ethernet cable connected to the mains electricity circuit.
NORMALLY, you'd have the Ethernet cable plugged into a router... and you'd use the Display Ethernet under System Preferences>Network when your ATD was connected via Thunderbolt port:
Like so...
Can you be a little clearer on where you have your ATD>Ethernet port connected?

Cisco RE1000 WiFi extender ethernet port question

Good morning - I have a RE1000 WiFi range extender which is unable to reach the far end of my house, an old barn with a thick stone wall in the middle (& the ADSL line enters at the other end of the building). I have tried various extender locations on both sides of this internal stone wall without consistent success.
A simple solution - IF the ethernet port is two-way - would be to run a 100ft long exterior Cat5 ethernet cable from my existing router to the far end of the house, into the RE1000 as its feed (as opposed to the RE1000 trying to pick up the WiFi signal from the router) & then any WiFi device at that far end of the house could connect via the WiFi signal from the ethernet-powered RE-1000.
Will this work, ie. will the RE1000 accept the ethernet signal as its source and transmit it onwards via its WiFi capabilities (or is the RE1000 ethernet port's only purpose to transmit wirelessly-received signals to a wired, non-WiFi-capable device ?) ?

The use of Ethernet port in RE1000:
"> Ethernet (green) Using Ethernet cables (also called network
cables), this Ethernet port connects Ethernet network devices
to your wireless network.
The green light turns on when an Ethernet device is connected
and active on this port. The light flashes when the extender is
sending or receiving data over the Ethernet port.

Selecting USB-ethernet or Ethernet Port

Hello,
I am running a Labview .vi suite on a laptop which has
1. Ethernet port connected to instrumentation via a DSL router
2. USB-ethernet converter connected to our work network (for accessing internet and sending data).
For reasons regarding our work network I cannot simply connect the work network to the DSL router so require a second port on the laptop.
The labview program communicates with the instrumentation via the ethernet port of the laptop. The labview .vi then spurts out data which needs to be broadcast via the USB-ethernet connection of the laptop to our work ethernet network.
So the communication of ethernet port to instrumentation is isolated from the network.
The problem I am having is that when the .vi runs it cannot connect to the instrumentation via the ethernet port because the USB-ethernet port is connected. When I remove the USB-ethernet port it can connect to the instrumentation via the ethernet port but data cannot be broadcast on the network via the USB-ethernet port.
Is there any way selecting the ethernet port in the .vi as it is impractical to keep removing and replacing the USB-ethernet port at just the right time.
Daniel

Hi Daniel,
The first step is to get both ethernet devices recognised correctly, at the same time, in NI MAX. Once you can identify them seperately in MAX you should be able to call them from LabVIEW.
Try adding your USB ethernet device as a seperate device in MAX and see if this helps.
Best Regards,
Chris

Ethernet Port Speeds on PowerMac G5

I just recently upgraded my cable modem and have it connected via a new ethernet cable to my Time Capsule.
My Mac Book Pro (2.4 GHz) and my 2004 PowerMac G5 (2.0 Ghz) are both connected to my Time Capsule via new ethernet cables.
I have been running SpeedTest.net on both computers and on my MBP I can achieve 32MB/s Down and 5 MB/s up. When I try the same test on my PowerMac G5 the speeds are 5-15 MB/s Down and 1 - 3 MB/s Up.
Since the Modem and Cables are new, both machines have Giga Ethernet Ports, and are connected to the the same Apple Router the I would think the problem is with my PowerMac. I am tempted to buy another ethernet card to fix this but I have a couple of questions before I do.
1) Any suggestions on really fast/dependable ethernet cards?'
2) I downgraded the Ethernet ports speeds to 100MB/s, saw some improvement, but not enough, is there anything else that can be adjusted with software (already have the latest firmware)
3) Any software to measure or test the port speeds other then Network Utility ?
Thanks,
Kevin

UPDATE -
I readjusted the Ethernet Port Speeds to 100mbs and rebooted the PMG5 and now I am getting much higher download and upload speeds from the net/router
Its seems the reboot made the difference - When in Doubt - REBOOT !

Ethernet port on 2010 iMac won't operate at Gigabit speed, but requires router to be set at 100 Base-T.

For almost a month I have been experiencing internet connection dropouts with my vDSL line, which had previously been stable for about six weeks since I changed ISP. I have an initially wired setup, from the router to my Time Capsule WAN port and from there to my 27" iMac Ethernet port. I bought new Cat 6 cables on setup.
During the router setup I was advised to set the active port at the Gigabit setting. Finally having discounted all other possibilities, the router manufacturer support engineer suggested I reset this back to the default 100 Base-T setting: and this has resulted in a stable connection once more.
Surely my iMac should offer functionality at Gigabit Ethernet transfer speeds? Otherwise the Airport home network is dependent on what my computer's Ethernet port can manage.

If you Google for non Flash speed test site you will find at least two, I have no idea how good they are hence not putting any links in the post.
As for pin pointing the problem, the only way I know short of having access to the internals of the router and TC including firmware source and test equipment is by producing the fault and swopping the various pieces of equipment out. Having access to the internals is way beyond anything I can do and swopping the parts out seems expensive.
From past experoence of Gigabit issuses I had it was usually down to cabling or faulty connections in the RJ45 sockets, this was quite common. As for the incompatibilty, one way to test is to put a 1Gb switch between the router and the TC.
I would not presume either the router or cable are good until proved.
There is always the possiblity that more than one piece of equipment is faulty, rare but I I have had it happen before.
Not a lot else I can say, perhaps someone else as more thoughts and can help.

How do I add an airport extreme to a cable modem with only one ethernet port, while keeping that port connected to my Mac?

I have a mac pro connected by ethernet to a cable modem via ethernet. There is only one ethernet port on the modem.
I want to keep the Mac connected via ethernet for speed. Is there a way that I can add an airport extreme to this set up - for my ipad and roku, and for guests to use - or do I need to buy a router to put between the modem and the mac?
If I need a router, what kind?
Thanks.

The modem connects to the WAN "O" port on an AirPort Extreme router.
The Mac Pro connects to one of the three LAN <-> ports on the AirPort Extreme router.
Or if you do not need the ability to connect a hard drive to the USB port on the router, you can save a bit by using an AirPort Express.
The modem connects to the WAN "O" port, the Mac Pro connects to the LAN <-> port
Either the AirPort Extreme router or AirPort Express router will allow up to 50 wireless device to connect.
There are many other wireless modems offered by other manufacturers as well.

Slow Internet Connection Speeds caused by Ethernet Controller Driver

Problem: Internet connection speeds are 1/10 of available connection speed.
1. Problem statement is based on running speed tests at cnet, speedtest.net, and AT&T.
2. I am paying for 12 MBps down load speed but I only get about 1.5 MBps.
3. Other computers in household get 11+ MBps connected to the same ethernet cable and also different ethernet cables.
4. I traced the problem to the network controller driver.
5. I updated to the latest driver with no change in performance.
6. After some experimenting I found that if I re-install the driver after the computer is booted up, the internet connection down load speeds increase to 11+ MBpS (typically around 11.4 with maximum capability of 12)
I have assumed that the driver does not load properly the first time, but why? Or is there some other cause or setting that I have overlooked?

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.

I have a MacBook Pro and all of a sudden I cannot get wireless internet connectivity to my router or any other router, I get connectivity through the ethernet port but not wireless. This was working well till this morning

What do you mean it did not work! What were the results of the diagnostic tests?
Have you contacted your ISP to determine if the problem is on their end?
Have you changed your router channel? Sometimes this resolves wireless problems.
