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.

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 .

WAN port inop and PM ethernet port inop - options to connect to AEBS?

Hi. We had a thunderestorm last week at home and we shut everything down and unplugged the power cords, but I think the cable to the cable modem fried some of my ports. I have a cable modem hooked to the WAN AEBS port and a cable from the LAN AEBS port to the ethernet port of my PM G4 867 (Quicksilver). After lots of troubleshooting with a different cable modem and my PB 15, it seems that the AEBS WAN port is dead and the ethernet port of the cable modem AND PM G4 are toast!!:( I guess all three got fried thru the cable.
I have a different cable modem that runs my digital phone so I connect thru it's ethernet port (after provisioning it). It works with my PBs directly and my airport express. I went to the Apple store and they confirmed the WAN was inop. Got a new AEBS. Now, here's my question:
I connect my PBs thru airport, but used the LAN to directly connect to the PM G4. The ethernet port is dead too. What should I do to get the PM connected?
I think the PM G4 quicksilver can accept an airport card (older kind). I can get one for around $100.
Is it easy to replace the ethernet card/port on this model? How much?
What's the best solution? What would you do? Thanks for your help.

I think the PM G4 quicksilver can accept an airport card (older kind). I can get one for around $100.
Yes the QuickSilver has an internal slot for the original 802.11b AirPort card. That slot is NOT compatible with the AirPort Extreme card.
Is it easy to replace the ethernet card/port on this model? How much?
There is no separate Ethernet card. The Ethernet port is built into the motherboard.
If you want Ethernet, the least expensive solution is a compatible PCI Ethernet card.

How can I check or set the Airport Express WAN port settings

I have a Netgear DG834G for ADSL connection with an Ethernet connection from the Netgear to a new (couple of months old) Airport Express. Performance for streaming and downloads has fallen significantly. On doing some problem diagnosis, I found that the Airport connection to the Netgear was showing as 10Mbps (an amber light), rather than 100Mbps. It should be 100Mbps (both devices support 10/100 Ethernet). I think the problem is with the Airport; I have tried different Ethernet cables and different Netgear ports. Other devices connect successfully at 100Mbps to the same port on the Netgear using the same cables.
Using the Airport utility I see no way to see any data about the Ethernet speed/duplex setting, nor any about how to configure manually.
Is there any way to do this?
Thanks for any advice here!

Unfortunately, there are no port settings available when the Express is configured in Bridge Mode, so no way to "test" things that way.
The Express should act just like a 10/100 Ethernet switch in Bridge Mode, so you may want to take the Express to an Apple Store or service shop to let them have a look if there is no other way for you to test the Express with the products that you have there.
If you want to experiment to test, you could temporarily configure the Express in router mode to see if the port behaves the same way. There are port adjustments in router mode, but I doubt that they will have any bearing on things when the Express is switched back to Bridge Mode.
The default mode is Automatic, which should work, but apparently does not. Try the 100 Mbps Full Duplex setting to see what happens.

Time Machine's WAN port doesn't light up, but Ethernet port does

Hi there,
We have a guest sleeping in the spare room where our Time Machine is also located and because of they are a light sleeper we've had to turn off the power at night. I've then noticed that it has become more and more difficult to setup my internet again.
Firstly, when I powered it back up, it began to flash amber and wouldn't recognise the modem plugged into the WAN. My first approach was to turn everything off and then turn them on again. This had worked the first few mornings after having the issue. But this method doesnt seem to fix the problem anymore.
Regardless, I now continue to receive the flashing amber light. For troubleshooting, I tested the internet connection direct to my Laptop and it worked fine, so I know the internet modem isnt the problem. I then plugged the internet into the Time Machine ethernet port and the green light began to work. I can also access the internet by airport through the TC with this connection.
My question is, why is the Time Machine able to detect the internet through the Ethernet Port, but not through the WAP port?
Also, by using this setup going forward, am I be putting myself at risk of any damage to my TC device, or exposing my personal data to the internet?
thanks for any and all suggestions.
Regards,
Elise

Is the TIme Capsule in Router mode or Bridge mode.. ??
It makes all the difference in the world.
How old is this TC?
It might be worth just doing a reset and set it up again.. make sure you use bridge not router if the modem already is running router function, otherwise TC will pop up an error due to the double NAT.

[SRP527w] Use Ethernet Port 4 as a WAN Port ???

English:
Hi everybody,
I just can't figure out how to use the ethernet port 4 as a WAN port.
I think it's possible since it's labelled LAN/WAN on the back of the device... If someone succeed, please let me know how!
Thank you for your help,
Gaultier.
Français:
Bonjour à tous,
Je n'arrive pas à configurer le port ethernet 4 en monde WAN.
Il me semble que c'est possible puisque le port s'appelle LAN/WAN sur l'appareil... Si quelqu'un a réussi, merci de m'expliquer comment!
Merci d'avance de votre aide,
Gaultier.

Hi Gauliter,
Please use the Administration > Switch Setting menu. Set the DSL Interface option to Disable to use LAN Port 4 instead of the ADSL interface.
Note, this setting will factory reset the router and completely disable that ADSL interface.
I hope this helps,

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.

Airport Express ethernet port for printing?

I've recently purchased an Extreme (802.11n) for my wireless internet service which is working just fine on its own. In the other room I've set up my older Airport Express for only networking my printers. I don't want to hook up the printer to the ethernet ports on the Extreme as it is near my TV and entertainment center. I understand I cannot use a USB hub to connect two printers to the Express, but is it possible to use the Ethernet port on the Express for my Lexmark E240 or any other ethernet ready laser printer?
Thanks
Al Powerbook, MacBook Mac OS X (10.4.10)

Hello Jeff Crowell...Welcome to the Apple Discussions!
I understand I cannot use a USB hub to connect two printers to the Express, but is it possible to use the Ethernet port on the Express for my Lexmark E240 or any other ethernet ready laser printer?
To activate the Ethernet port on the AirPort Express Base Station (AX), you need to configure it as a Remote Base Station in a Wireless Distribution System (WDS)...
Wireless Distribution System (WDS) - Remote Base Station Setup
(Note: To facilitate setting up the Base Station(s), place them in near proximity of each other during the set up phase.)
Either connect to the AX's wireless network or temporarily connect directly, using an Ethernet cable, to the Ethernet port of the AX, and then using the AirPort Utility (in Manual Mode) to make the following settings:
AirPort - Wireless tab
- Wireless Mode: Participate in a WDS network
- Network Name: <existing AirPort Network Name>
- Radio Mode: 802.11b/g compatible
- Channel: 1
- Wireless Security: None
AirPort - WDS tab
- WDS Mode: WDS remote
- Allow wireless clients (enabled)
- WDS Main: <MAC address of the Main Base Station>
Internet - Internet Connection tab
- Connect Using: AirPort (WDS)
- Configure IPv4: Using DHCP
- Ethernet WAN Port: Automatic (Default)
- Connection Sharing: Off (Bridge Mode)

Win 7 desktop on ethernet port of Airport keeps dropping internet.

While it may sound similar to many others, this exact question hasn't been asked before, or 2 weeks of sleuthing hasn't found it.
Thinking I was doing him a favor, I convinced my boss to upgrade his old Linksys wireless router with a new Airport Extreme base station.
I have a Dell UnInspiring 850 running Windows 7 that is connected to the ethernet port of the Airport Extreme base station (the desktop doesn't have a WiFi card)
The WAN port of the Airport Extreme base station is connected to the DSL modem (which only has one in and one out port, so I cannot connect the desktop directly to it)
The Dell desktop keeps losing its internet connectivity (even though Network and Sharing says that it is connected and not one Windows 7 troubleshooter seems capable of troubleshooting anything), when left idle for more than an hour. For a while, refreshing the browser fixed it, but doesn't anymore. It now requires unplugging the Airport and the DSL Modem, which is justifiably trying my boss's patience. The 3 Mac laptops, the 1 Mac desktop, and the 1 Windows XP laptop are all perfectly happy and don't drop their internet connections, so it's not a problem with the Airport, it's a problem with Windows 7.
I have upgraded the BIOS on the Dell Desktop
I have upgraded the BIOS of the NIC card of the Dell Desktop
I have changed the Networking Group from "Home" (which I found out REALLY means a pure Windows 7 network, which has nothing whatsoever to do with the physical location of whether this PC is in a house or an office building), to "Work" (which I found out REALLY means a network of mixed operating systems).
I have done the command line ipconfig /all stuff.
I've called the ISP, who says there aren't any special settings necessary.
I've tried changing the Airport Extreme from its recommended Bridge Mode (which works for everyone), to all manner of other configurations, none of which work.
I've pulled half of my hair out.
My boss now wants to send back the Airport Extreme and buy a new Linksys. I can't say that I blame him, even though it's not the Airport's fault. Any ideas on how to fix this? I am now going to try and downgrade the firmware of the Airport in order to dumb it down for Windows 7 and am even going to resort to going into the registry (which is yet another suggestion by yet another frustrated user, since every user is valiantly attempting to solve this widespread problem). Simply buying him a Mac Mini would make this so much easier of course.
If someone who works at Microsoft sees this post, could you please get this problem patched and fixed once and for all instead of continuing to ignore it? This is why you're losing market share and customers...to Apple.
Thanks and apologies for the tone, but can you blame me?

I finally have time to read this forum to see if I can find a solution to what appears to be the same problem BrooklynBlueEyes has. In my case, I brought home an extra PC we had from work for my wife to use (to keep her off my mac). It had been upgraded to Windows 7. I just had bought an Airport Extreme, which works wireless and also through the wires we have running to all of the rooms. I have tried to get the PC to work (wired) through the Airport Extreme, but nothing I tried seems to work. I called the IPS (Comcast), which said it was an Apple problem. short of uninstalling Windows 7, is there anything I can do? I am not very techno-literate, so if you could keep any explanation on the simple side, it sure would help.
Thanks.

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.

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...

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.

*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

Google provides free dns lookup too. There numbers are:
8.8.8.8
8.8.4.4

I suggest that you try pinging Google.com.
Macintosh-HD -> Applications -> Utilities -> Terminal
mac $ ping -c4 google.com

Analysis: If you cannot ping Goolge.com but you can ping 64.233.187.99, then you need to enter you dns address. For some reason Mac OS X sometimes doesn't set the dns. You can set it manually.
apple > system preferences > network
tcp/ip tab and enter address of dns servers
example 162.33.160.100
You will need to use a different number.
PS.
You are a little short on stating results. You state what you did, but I have to guess the result.
Did: X
Result: Y
Did:
1) Power Book's ethernet cable plugged into router port 5. Working to yahoo.com.
2) Unplugged power book's ethernet cable from router
3) Plugged eMac's ethernet cable into port 5.
Result: eMac using Firefox was not able to access yahoo.com

How do I add an airport extreme to existing time capsule network and be able to use the router ethernet ports?

Good day everyone. I recently upgraded my airport extreme network by replacing the base station with a time capsule router. Since I now have an "extra" airport extreme router, I've set it up on the other side of the house to both extend the wireless range as well as use it's LAN ports for a home theater system in that location. Connecting the two routers was done via ethernet. It now appears that I need to do something "else" as the LAN ports on the now relocated airport extreme are nonfunctional. All devices are operating well for wireless and as a review, the modem is connected to the time capsule WAN which is connected to the airport extreme via ethernet cable via LAN to it's WAN port. What do I need to change on configurations to get the LAN ports functioning on the airport extreme? Thank you for any help.

With both base stations interconnected by Ethernet you have the basis for a "roaming" type network. If properly configured, both base stations' Ethernet ports would be enabled for wired clients.
The key configuration items for a roaming network are as follows:
All base stations used must be interconnected by Ethernet.
The "main" base station; the one connected to the Internet modem, must be configured to provide both NAT & DHCP services; all other base stations used must be configured as bridges (NAT & DHCP disabled.)
Each base station must have a unique base station name.
Each base station must use the same wireless security type and password.

WAN Ethernet Port Settings?
