BT HomeHub Ethernet port settings

What is the recommended setting for devices connected to the Ethernet ports of the BTHH 2.0 ?
I don't trust Auto-negotiation, should I fix to 100mbps and Full duplex?
Are all 4 Ethernet ports configured identically?

Leave everything at Auto and it will be fine.

  • WAN Ethernet Port Settings?

    Under the Apple Airport Admin Utility/Internet tab there is a button marked WAN Ethernet Port. This button gives you several options, including "Automatic", and then four other options referring to what I guess are port speeds, and the terms "Half Duplex" and "Full Duplex". Any one have a clue to what these are/mean? What should I choose to maximize my Base Station?
    I'm running a LinkSys Cable Modem into my Base Station. Right now I'm supposed to be getting 8 MBps service thru Comcast. But I'm only maxing out at about 768 kbps.
    eMac 1.25   Mac OS X (10.4.6)  

    Those all have to do with ethernet port speed and transmission of data. Automatic means the ethernet port will try and sense what it is connected to and set the correct port speed and duplexing level. The duplexing means transmission of data. Half duplex will transmit data in just one direction at a time and full means that it will transmit and recieve at the same time. A walkie talkie is an example of half duplex and a telephone is an example of full.
    Usally setting it to automatic is the way to go but you want to make sure each side is the same. Make sure whatever your cable modem is set to (Automatic, 100/Full, 100/Half, etc.) is the same on the WAN port of the AE.
    If not you will receive CRC errors etc causing slowdowns and retransmission of data.
    I hope this helps.

  • Set-VMNetworkAdapterVlan throws Failed while applying switch port settings 'Ethernet Switch Port VLAN Settings' error

    Hi,
    I'm following this

    Hi TomG101,
    It seems that there is a configuration conflict on the virtual switch port .
    Also I tested the command on my lab , it works .
    For troubleshooting please  create a new virtual switch then try to configure again .
    Any further information please feel free to let us know .

  • I had a failure of a dsl modem which inturn destroyed my ethernet port of non isight imac G5.  In attempt to solve the problem I did a clean install of leopard 10.5.4. I am unable to upate to 10.6,.7  or .8 without freezing system network preferences

    Dsl modem failure caused malfunction of ethernet port.  In attempt to solve problem I did a clean instillation of  Leopard 10.5.4 and then update to 10.5.5 with access to internet through apple usb to ethernet adapter.  If I attempt to update software to 10.5.6, .7 or .8 it freezes my network system preferences and computer will no longer shut down.  The network connection assistant also no longer sees a connection to the internet throught the usb/ethernet adapter.  I have checked they systerm Tech tool deluxe which shows no problems and also used hard drive utility on instillation disk which found no problems.  Permissions were also checked as well and no problems noted.  Any thoughts as I really like my imac G5.

    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
    If all the above fails, then it appears to be time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

  • Airport Extreme - creating a wired local network from a cellular hotspot without ethernet ports?

    Forgive the book I've written below, please. I generally think too much info is better than not enough... I'm looking for assistance and/or suggestions since I have been unable to locate solutions on my own so far. Searching this forum has found a great number of "sort-of" related things, but all of them so far appear to involve apple-only hardware or upstream network devices which have ethernet ports. Nothing that seems to match my situation enough to extrapolate out. Maybe I'm just using the wrong keywords. Anyway....
    I've recently moved to a particularly rural area with no wired internet access to speak of (well, I suppose there is dial-up, but... yeah). I've tried several different wireless varieties including satellite, the AT&T Elevate 4G hotspot and a service that used an EVDO-cellular solution(a sprint-based reseller).  The former had serious latency issues which I had predicted and so was right-out. The last had signal coverage problems which their maps did not accurately reveal. Their potential mitigation was to have me invest even more money into a super-mega antenna to be roof-mounted. And even that was an uncertain fix. The AT&T solution with the 4G hotspot has been AMAZING so far and I love it. Coverage is great, latency and bandwidth fantastic.
    I love it but for one exception, that is. Connectivity options.
    There is a particularly limited number of WiFi connections available and only a USB network adapter for a single computer. None of my wired-only network devices can connect directly and I have significantly more WiFi connected devices in general use than the device supports.
    I have an Airport Extreme that I was using as my primary connection point through a FiOS router at my previous home(and both the satellite and EVDO modems at the new place). Never had any problems with it when feeding its WAN port with one of the various routers' LAN ports. However, as has been evident by reading all sorts of posts here and elsewhere, having it connect via WiFi to the Elevate means that the ethernet ports are disabled. Not terribly useful.
    The Elevate has no ethernet ports. Only WiFi and USB network connectivity.
    The Elevate does not appear to have settings available to create a WDS network-- so it cannot be "Extended" via those methods, either, as far as I am able to tell.
    So these are some thoughts I've had. Before I invest the time and money into them(both of which are in extremely short supply lately), I'd like to know if anyone else has already solved the issue or can tell me definitively whether these ideas, or some I haven't thought of, will or won't work. Any helpful feedback or thoughts would be sincerely appreciated.
    Options I've considered, but are uncertain:
    -A Wifi/Ethernet or even ethernet-only router which has a USB WAN uplink(I've had a few bites on searching, but nobody seems 100% clear on the capability for the models I've located). I could plug the Elevate into that USB port and then from there I'm golden. If this is the best option, then can someone recommend a brand/model that they know will work in this way?
    -WiFi Access Point (Airport Express, maybe?) that will connect to the elevate via WiFi, and then use its single Ethernet port to serve as the APExtreme's WAN uplink. (I don't know if this will work at all, actually...)
    -Connect to the computer via USB, run some kind of network bridging software (which I don't know what the heck that would be) to bridge between the USB Network and the Ethernet port, then run a hard wire from there to the APExtreme's standard ethernet WAN uplink. This is going to be a "last resort" option since it involves software I'm unfamiliar with, even unsure of availability for Mac, and requires the computer to be running and configured properly at all times. Given the way my kids abuse a computer, I can't be certain of anything involving this option.
    -Some secret method of turning on WDS capabilities in the Elevate which would then allow my existing base station to become a second node in the chain. I really wish someone could tell me this is possible if only I'd push the right buttons. I see this is as the absolute best option, if it can be done. Cheapest, anyway.
    Current set-up:
    AT&T Elevate 4G hotspot
    WiFi connected devices(rotating since Wifi connection count is limited): Mac PC, 2 iPads, 3 iPhones, Apple TV, a Nokia mini-tablet, a Kindle fire, Wii, XBox 360, an old dell laptop issued by my office.
    Apple Aiport Extreme base station
    Wired connections: blueray player, television, satellite TV pay-per-view uplinky device thing.
    Please, tell me your thoughts?

    Had the same issue here.  Here is the best solution I have found so far:
    Hotspot + Pepwave Max On-The-Go (w/ Load Balancing) + Airport Extreme
    I have a VZW MiFi, but I believe this set-up will work with other hotspot devices.  I actually have 2 MiFi Hotspots with a monthly allowance of 20G each.  They are plugged directly into the Pepwave router (aka, tethered).  (Note:  you have to have the right cable to do this.  The one that came with my Hotspot was only for charging.)  If, for some reason, you cannot tether with your Hotspot device, you want a router that offers WiFi as WAN.  The Pepwave will do this.  The Pepwave is connected to my Airport Extreme via ethernet cable.  I have the WiFi on the MiFis and the Pepwave turned off.  So the only visible network is my Airport Extreme.  The Pepwave is essentially just functioning as a modem.
    I used to have a Cradlepoint, but I did not find it very user friendly--too complex for home use.  The Pepwave Max OTG is awesome.  I got the one with Load Balancing so it allows you to connect up to 4 cellular devices.  If you only need the one Hotspot, you can just get the cheaper Pepwave Max OTG.  The Pepwave allows me to run off one of the MiFis until I hit my 20G/month allowance, then it automatically switches to the other one.  That way I never max-out on my monthly data allowance.  Additionally, it gives you a real-time, hourly, daily and monthly running tally on data usage.
    The guys at the 3Gstore are excellent and can help you figure out the best solution for your situation.

  • No internet access via ethernet port

    Hi, have been using my emac via ethernet cable to router, for many months with NO problem accessing internet and others cabled to same router also having no problem and I have used my Pwr Mac wtih no problem and have never had to make any specific settings to either to access the net via the router which gets its wifi signal from elsewhere. With system preferences > network > ethernet open I can see the the router is being recognized cause it appears or dissappears as soon as I plug or unlug the ethernet cable. I open "Activity Monitor" and occasionally, very briefly, there will be data incoming( green spikes ) or outgoing( red spikes ). HD verified OK, ran disk permnissions and scripts. Have not yet run Apple or other( Micro-mat ) hardware testing programs tho I will later. Does anyone know if there is a PLIST file that can get corrupted that would affect ethernet port functioning properly? My guess it is hardware but since I can see the router is recognized makes me wonder about corrupt file ergo a system error or possibly inloaded some file that caused conflict. I also booted from my external drive and tried accessing from the cloned OS system and still did not work. The cloned system is the original has never been updated, nor has any of the applications in clone, so, if it was "system" problem the clone should have worked. However, I had cloned user ergo newest documents, library etc, so that would be the only possible source of conflicts when booted from clone system....Thx Ran

    Ping test should be interesting.
    Start by pinging router address. Should be able to ping building router if you can figure out it's address.
    Could you go wireless to building net? You might buy a usb dongle.

    *MAC Address*
    Every ethernet port has a unique MAC Address. A router can block on a MAC Address. That is why I suggest you check out your router.
    Note MAC is not Mac. MAC is all upper case.
    definition: http://en.wikipedia.org/wiki/Mac_address
    *Ethernet port hardware*
    I'd say this was some kind of strange hardware problem.
    *Dns problem?*
    It has symptoms of a DNS problem. The little traffic is a symptom of the problem. You said all the numbers were the same, however.
    Verify DNS
    apple > system preferences > network
    Double click on network connection you are using.
    Pick the TCP/IP tab.
    Verify that you have a DNS Server. If you do not, look on your windows machine and see what the net address is. You can also pick using DHCF and still enter you DNS server address.
    You can use
    harddrive > applications > utilities > network utility
    to diagnose the situation.

  • How can I make the 10/100BASE-T Ethernet port on my Airport Express work as a LAN-port? The AE is currently extending my network (generated by a Time Capsule)

    Dear all.
    I currently have a WIFI-network established by a Time Capsule. I want to use my Airport Express as WIFI-receiver for my Samsung TV. How do I pair them up so that the 10/100BASE-T ethernet port works as a LAN-port? I used to do it by setting it up as WDS but I understand this is not suitable for a "n" network.
    Thx.

    Under the wireless settings for the TIme Capsule, make sure that there is a check mark next to "Allow this network to be extended"
    Then configure the AirPort Express to "Extend a wireless network". The Ethernet port on the Express is automatically enabled in this type of configuration and the AirPort Express will also provide more wireless coverage in the area where it is located.
    See Apple's instructions in the link below. The iilustration shown in the support document shows an AirPort Extreme as the extending device, but the setup for the AirPort Express would be exactly the same

  • My Apple TV is a useless brick now.  Ethernet port no longer works.

    Not sure, but it seems after an update, my ethernet port does not work.  I can plug it into the PS3 and works fine.  I HAVE TO use WiFi now or my Apple TV is a useless piece of plastic that looks "oh so Apple Cool."  Yea, whatever Apple.  I have been using this same port for almost 2 years with no issue.
    thoughts?

    It may well be a hardware failure but a few things to try:
    Unplug from main for 5-10 mins and restart it.
    Reset settings in the Settings menus.
    Last resort - try to factory restore to current software using a microUSB cable to hook it up to a computer running iTunes.
    Assume you don't have Apple care (even if you did I think it's only 2 years on AppleTVs anyway).

  • 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.

  • HP 7210 All-In-One Ethernet Port not working

    The green Ethernet port light is not lighting and the computer can no longer find the printer.  I believe it may have been damaged by a power surge during a lightning storm.  I have checked the Ethernet cable that connects it and it is working fine with my laptop so it is not the cable coming into the printer.  The printer works fine with the USB cable and all other printing, faxing and copying functions are working fine.  Is it possible to repair or replace the Ethernet port?
    I have also tried setting the IP address back to default and manually setting the IP address.  The port is just not recognizing the cable.

    Jim B - First, thank you so much for helping me.
    I was able to get the green port light to light-up by performing the steps 1 - 5 you recommended.  Also the amber data light is on but not blinking.  In fact now they both stay lit even when the cable is removed.  When I use the same cable with my laptop the green light comes on and the amber light blinks.
    Unforntunately, the printer is still not finding the IP address.  I tried the function to "Restore the Network Defaults" and I also tried to manually set the IP Address.  When I print the network settings it indicates the status is "Offline" and I have the following changes:

    Hi
    I am planning to use my raspberry pi to do a few projects, but it is not near the router (needs connection thought  Ethernet - and before anyone asks im not able to use a wifi dongle to connect due to project requirements size wise ) but near my officejet 6700, can i use the Ethernet port on the printer to connect my raspberry pi to the network the printer is connected to. Do i need to fiddle with settings?
    Can anyone help
    Thanks in advance

    No you can not use the Ethernet port on the printer.  This is only to connect the printer to a wired network.

  • Cluster via Mac Pro second ethernet port?

    I'm on an enterprise 10/100 LAN and want to link two Mac Pros together for a cluster. I don't want to use the Internet Ethernet-1 port because it's slow and IT will probably throw a fit if they figure out I'm transferring massive amounts of data over the network. Consequently, I'll try to get a 1000Mb router and make my own gigabit LAN linked into the building network, however, IT will throw a fit if someone is operating behind a firewall inside their precious network.
    Anyway, until I get this router situation worked out, I would like to link the two machines via a single Ethernet cable, while still retaining my Internet connection on the other port. In my trials, this doesn't work. I appear only able to use the active Ethernet port w/ the LAN.
    Any ideas here?
    Also, any suggestions on a reasonable quality router would be bonus help.
    Thanks

    I've tried this before a while ago. I had the LAN/cloud setup on port 1, and directly connected to another Mac on port 2 and no dice w/ manual network settings. IIRC, I couldn't even select it in Qmaster.
    I guess, first, has anyone got this to work? I'll give it another shot, but it would be nice to know someone has got this working before I start banging my head again.

  • 1 Ethernet port

    Greetings,
    I just bought an iMac (had a dual processor PowerPC G4) and now find that it has only 1 Ethernet port. I have an Ethernet hub, but my Internet cable connection (comcast) doesn't work when it's connected via hub. Therefore, I have to use the iMac Ethernet port for cable, but also need it for the printer. Is there something like a 2-port Ethernet jack, like a double phone jack, available? I've Googled it, but may be using wrong terminology. Any help would be appreciated.

    I use Comcast cable for Internet broadband, and you can definitely use a router. No self-respecting ISP would deny the use of a router. It is possible that you need to upgrade your cable modem, if you have had it for a few years. Comcast should be willing to swap it out at no cost.
    A router acts like a single-purpose computer. It handles the connection to the cable modem and the ISP's network, taking the place of your computer (which often needs to run special software or have special settings if directly connected). With the router in place and handling the connection for you, your computer does not need to run any special software or have special settings; it is just part of the local network. You just need to set up the router with those special settings, as specified by Comcast for your area.
    I use an AirPort Extreme as my router. Previously, I used a cheap Linksys wired router (until it broke after a few years of good use).

  • Ethernet port is erratic

    When I try plugging in an ethernet cable to my ethernet port, it generally doesn't work. Sometimes I can move it around a little while simultaneously pressing refresh on my browser, and it will work... but this isn't very often. This was the case a few months ago, but lately I can't get it to work at all.
    Is this something AppleCare will cover?

    The way you describe the problem, pressing the browser refresh would have nothing to do with fixing it or not, and yes, AppleCare would cover a faulty port.
    Resetting your PMU will return your hardware settings to default values, including NVRAM.

  • Is there a fix for a dead ethernet port besides a new logic board?

    My ethernet port went dead on my IMac.  I unplugged the ethernet cable and plugged it into my laptop and it worked instantly.  I am still able to connect wirelessly.  I bought an apple USB to Ethernet converter and plugged it in.  It worked for about 3 days and then it went dead.  Once again I was able to unplug the ethernet cable, plug it into my laptop and instantly had a connection.  Is there a fix for a dead ethernet port besides a new logic board and if not how do I figure out which logic board I need?
    Thanks

    This problem baffled me. I kept getting the "ethernet cable unplugged" error after testing my cables good. Was abut to write it off as port gone bad when I found this thread.
    The YouTube video reference above fixed my problem. (http://www.youtube.com/watch?v=u1P6X87qArs)
    Basically go to SETTINGS/NETWORK. Then highlight your ETHERNET port and click the ADVANCED button. From there click the HARDWARE tab.
    Set
    CONFIGURE to MANUALLY
    SPEED to whatever your ethernet speed is, in my case 1000baseT
    DUPLEX - FULL DUPLEX, FLOW CONTROL
    Leave MTU at Standard
    Hit OK.
    Then don't forget to hit APPLY. I didn't do this the first couple of times assuming hitting OK applied these settings. You gotta hit APPLY.
    In about two seconds, my Ethernet connected again.
    I went back and reset it to AUTOMATIC just to test and after doing so got the cable unplugged error again. So I am leaving it on manual and it's working.
