Creating a subnet via ethernet

Very technical question here:
I have a MBP and a NAS server which runs Windows xp pro (for certain reasons)...
anyways, I have both computers using their respective wireless cards for the internet... both have gigabit connections so I looked into connecting the both of them at home to back up the mac apps / music etc to my desktop via Ethernet..
Is possible to have the apple maintain it's wireless connection and connect to the server via a subnet or something using the Ethernet?
This would be a life saver.. think of it as 2 internet solutions working at the same time using different protocols.

You will need to run a DHCP server on either the MBP or server. Alternatively you can use static IP addresses. From the question it looks like the MBP and server are both still able to access the external network via the wireless router, as opposed to, say, the MBP's packets being routed through the server then to the router. In this case, you need to ensure that the default gateway is via the wireless interface. You can use the route command, via Terminal, to get the right routing / forwarding table.

I'd like to alter my Airport Extreme/Airport Express wireless network so that the 3 Expresses connect to the Extreme via Ethernet. I've been told this will create a more stable wifi signal. How do I configure this using Airport Utility? Thanks.

I currently have an Airport Extreme Base Station connected to my DSL router by Ethernet. Because I have a long, sprawling home, I have 3 Airport Expresses configured to "Extend the Wireless Network" I've established. Because of my home environment--thick walls encompassaing wire mesh, sprawling rooms, etc., it is hard to maintain a continuously-strong, stable WiFi signal. I've been told that I can create a much more stable network by connecting the Express units to the AEBS via Ethernet cable. Since my home is already wired for Ethernet, I'm considering making this change. If I proceed to establish the Ethernet connections, how do I then set up Airport Utility to accomodate this switch from a Wireless-based WiFi network to an Ethernet-based WiFi network?
Thanks in advance for any help.
Phyllis

I don't see anyplace in the Utility to designate HOW the Express units are connected, only how they relate on the network to the Extreme,
As I mentioned in the previous post, when you click the Internet icon in AirPort Utility:
Connect Using = Ethernet (This tells each Express to connect to the Extreme using the ethernet connection)
Connection Sharing = Off (Bridge Mode) (This setting allows your AirPort Extreme to function as the "main" router on the network, as it must for the setup to work correctly.
You do not need to configure anything differently on the AirPort Extreme (as long as it is working correctly now) to connect the AirPort Express devices.
The only other question I have is the following: I'm currently already using one of the Ethernet ports on the back of the Extreme-- for my husband's iMac. I really don't think he gains much in performance over how the iMac would run through wifi, so I could disconnect the iMac. If you think the iMac would do better to stay on the Ethernet connection, should I use a switch/splitter to add an extra connection?
Since each AirPort Express must connect using ethernet, you will need to use the 3 LAN <-> ports on the AirPort Extreme for the AirPort Express devices.
I would suggest that you try connecting the iMac using wireless to see if that will work. If the wireless connection is not satisfactory, then you can add a 5 port ethernet switch to one of the LAN ports on the Extreme and then plug all the devices connecting using ethernet....the iMac and the 3 AirPort Express devices...into the remaining 4 ports on the switch. That will leave you with 2 open ports on the AirPort Extreme for any future devices that may need to connect.
When you test out the system, here is a trick to find out which device your computer is actually connecting to at any given time as it "roams" around the house.
When you have AirPort Utility open to configure each AirPort Express, jot down the AirPort ID for each Express. You can do the same for the AirPort Extreme.
As you move around with your laptop, hold down the option key on your Mac keyboard while you click on the fan shaped AirPort icon at the top of the screen. Look for the BSSID. That is the AirPort ID of the device that the laptop is connected to at that time. it should also be the ID of the closest AirPort Express (or AirPort Extreme if the laptop is close to the Extreme at the time).
Let us know how things are working when everything is up and running.

I transferred files and photos from MacBook to iMac via ethernet cable and using migration assistant. However every time I transferred, it created a separate user and it transferred all files and photos again and again. So now I have 3 users accounts ?

I transferred files and photos from MacBook to iMac via ethernet cable and using migration assistant. However every time I transferred, it created a separate user and it transferred all files and photos again and again. So now I have 3 users accounts with all files and photos saved 3 times on same iMac !! Any idea how to avoid this ?

Yes, you ran into a very understandable problem.
When you use Migration Assistant, it cannot over-write the account that you happen to be using at the time. Upon migrating accounts, it will tell you that it is going to create a new one, but that message is easy to miss.
If you have three identical accounts, log in to the account you want to keep, and delete the redundant ones in System Preferences > Users & Groups.
Now that you know, the easiest way to migrate accounts is to use Setup Assistant when you first get a new Mac. That eliminates any possibility for this to occur, but most people are so eager to use their new Mac that they elect to migrate later.
That's OK too, but in that case you would want to create a temporary account whose sole purpose is to run Migration Assistant so that you may migrate your old one with an identical name. Be sure to give the new account Administrator privileges. When that finishes you would log in to the newly migrated account, and delete the temporary account.

Network mode: Create a wireless network vs. Extend wireless network via ethernet

Can some one tell me the difference between configuring AirPort Utility : Network mode: Create a wireless network vs. Extend wireless network via ethernet? I connect my cable modem to my Airport Time Capsule to a network switch via ethernet. The switch contacts to three Airport Express (AE connects to two Apple TVs via Ethernet) and another TC. Which is the best mode to configure my network?
Thanks

Create a wireless network is used only when the Airports have an Ethernet connection. If you are using the setup wizard.....the setting will read Extend using Ethernet during the setup. If you go back in using AirPort Utility to check the Network Mode setting.....you will see that it is really Create a wireless network.
Extend a wireless network is used only if an AirPort is connecting to another AirPort using wireless.......not Ethernet.
Every one of the Airports on your network must be configured to Create a wireless network.
If you do connect an Ethernet cable to an AirPort that is already set up to Extend a wireless network......that will create a massive feedback loop that will crash the network until you remove the Ethernet connection to the device.
The bottom line here might be if you are using the setup wizard, it will make the correct choice for you.

Airport extreme won't connect via Ethernet to BT homeHub v2.0

Hi
here's what I want to do:
1. Homehub is connected to the phoneline and will provide a b/g network for my iphone/xbox/laptop1
2. I want to connect my airport extreme to this (from what I can tell this must be done through an ethernet cable) so that I can have a separate N network which only 1 laptop will connect to.
So the problem I have is that no matter what options I select in the airport extreme when it's connected via ethernet it tells me that nothing is connected to the Ethernet WAN port. I've tried two different cables different ports on the back of the hub etc. nothing works. Every time I search google or forums for an answer people just write "connected it via ethernet and it works great" but there's no guide to what settings to use that I can see.
Can someone please help me with some sort of noob guide to get this setup how I've stated?
Many thanks in advance

Hey Bob
thanks fro the quick response. I have actually tried exactly that but it still flashes orange at me I'm suspicious that the AE may have a fault because during the setup (i can't remember the exact steps) but I got the AE updated and it complained that it could read from the AE (error code was 10057). Googling this does thow up a couple of solutions which I haven't tried.
so my steps should be:
Factory Reset the AE
setup as join existing network
join via ethernet to create a 2nd network
connect up the cable to the WAN port and the Lan of the Hub
change to bridge mode.
One thing I did notice (which may or may not be related) is the subnet mask on the AE says 255.255.0.0 when I set it up like this. However when I make it just join the network without trying to create a new one (which works) it sets it to 255.255.255.0 . the IP address also begins 192.168.1.* whereas in the other setup mode it is something different. Does that matter at all?
Thanks

IMac G5 won't connect to internet via Ethernet

So i have an iMac G5 that isn't connecting to the internet via ethernet.
I have already taken a look through all the Network Preferences, tried going through the network port configurations and setting all of that up again, created a new location for it.
I tried turning off the modem, and letting it restart - restarted the iMac - tried to set up all of these settings again.
I also created a test user account to see if it would work there - still nothing.
I hooked my own 17" MacBook Pro to it and it works perfectly. I never had to go through any settings on mine - it just worked as soon as i plugged the Ethernet cable in.
So the modem itself works - because my computer works. What else could be the problem?
I went through the Network Diagnostics on hers - all green dots and it says that the internet connection is working perfectly. It gives me an IP address - but it still won't load a webpage, and it tells me there that i am not connected to the internet. I am all out of ideas.
If anyone can help me with this it would be greatly appreciated. Thank you so much!

What OS you using? 10.5?
My memory of 10.5 is fading so you may need to figure out the vague instructions.
To make this easier to type Macbook Pro = MBP
When testing disable wifi & use ethernet on both machines.
Are both set to use DHCP? Or are you using manual settings?
Compare the IP addresses of the MBP & the iMac when they both use ethernet.
Compare the subnet masks too just to be sure nothing is different.
Does the iMac do any local networking at all? (e.g. is iTunes or File sharing visible on it). see *
Does it see the MBP in the sharing sidebar or can it connect to anything on the local network?
Have you connected the MBP to the iMac using the exact same cable that the iMac connects to the router?
Does the MBP work if connected to the router using the iMacs ethernet cable?
* You will need to enable file sharing to see the shared Mac in the sidebar (or have mother service shared). Enable it in System Preferences > Sharing whilst you test.
If you are have local networking in a functional state it could be…
DNS - what is the iMac DNS set to on each Mac?
Are either of them showing a grey DNS entry in System Preferences > Network? That means the router is supplying that info.

Cannot connect to iMac (OS9) via ethernet while connected to internet

I readily connect my eMac (OS X) to my iMac (OS 9) via ethernet using TCP/IP except when my internal modem is connected to the internet. In Network Port Configurations, I have ethernet at the top of the list, followed by fire wire and then the modem. It appears to search the internet.
Any suggestions?

On the iMac, the AppleTalk Control Panel (CP) is set to connect via ethernet. The TCP/IP CP is set to connect via Ethernet, Configure manually with an IP and Router address of 192.168.168.1 and a Subnet mask of 255.255.255.0 The IP address shows up in the File Sharing CP which is set to use TCP/IP.
On the eMac, PPPoE is disabled and Appletalk is active. Connecting from eMac to iMac works fine when the eMac's internal modem is idle but not when it is connected to the internet.
When I try to connect from iMac to eMac while eMac is connected to internet, I see the eMac in the Chooser and can attempt to connect as either registered user or guest but then immediately get "The connection to this server has been unexpectedly broken". If the eMac is not connected to the internet, I can connect as a guest and see items in my Public folder.
I tried creating a new Location and immediately lost my internet connection.
The IP address of the iMac never changes. I do enter the IP address of the eMac's ethernet into the chooser dialogue on the iMac when attempting to connect from iMac.

How do I connect a PC via ethernet to my new Airport Extreme router?

I just replaced an old Actiontec router with a new Apple Airport Extreme router to work with my Verizon FIOS service. Connection to all Apple products via ethernet or wireless works OK, however I cannot get the PC up and running via its ethernet connection to the Airport Extreme. Any help would be much appreciated.

If your other devices are working then it is probably the PC's IP configuration.
First, make sure that the PC is actually connected to the Extreme by verifying the lights are on at the Ethernet ports on the PC and the Extreme.
If you are using DHCP to manage the IP addresses then make sure that the PC is configured to "Obtain IP Address Automatically" for both IP versions 4 and 6.
When I replaced my Linksys w/ an Extreme I forgot that I had a couple devices configured with static (manual) IPs. My old one used the "192.168.1.nn" and my Extreme defaulted to "10.0.1.nn". Once i converted all the static IPs to the correct subnet then all was good.

I have a Airport network at home with a Time capsule connected via ethernet cable to modem. Also the network is extended wirelessley with an Airport Extreme. I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme. Can my network operate properly to extend the network with both a wireless and wired extend functionallity?

I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme.
Excellent plan.
Can my network operate properly to extend the network with both a wireless and wired extend functionallity?
Yes, but don't get confused about the second AirPort Extreme, as it would not be configured to "extend" a wireless network.....it would be configured to "create a wireless network" using the same wireless network name, security settings and password as the Time Capsule network. Configure the second Extreme in Bridge Mode.
This Apple support document will show you how to hookup and configure the second AirPort Extreme:

Connecting Airport Express (n) to WRT54G via ethernet

I am using Airport Express (n) currently and would like to connect to Blu-ray player with ethernet for netflix streaming. But as we all know, the AX has only one ethernet port. I have an old linksys' WRT54G. Is it possible to use this as a part of network without loosing the advantage of Wireless N network? My idea is to go from Cable modem to WRT54G, and WRT54G's LAN PORT out to AX. WRT54G and AX will be connected via ethernet so that it doesn't lose the advantage of the N network.
And Blu-Ray player will be connected to WRT54G via ethernet.
Can someone tell me if this works and if so, how do you configure each device so that you don't have ip address conflict or any other problem. Thank you.
Message was edited by: Kozo Okumura

Certainly that will work. Since they are connected via Ethernet, the wireless clients of the WRT54G will have no effect on the wireless clients of the AX.
The WRT54G will provide a 802.11b/g network while the AX can provide an 802.11n network.
The AX should be configured to create a wireless 802.11n network and it should be configured to act as a bridge (not sharing a single IP address).

Airport Time Capsule 3TB can't connect to modem via ethernet

Hi all,
Thanks in advance for any assistance on this issue ...
I am having extreme difficulty in connecting my Airport TC to my modem via ethernet. Ideally, I want to use it to extend the range of my wifi, as well as back up my machines.
I can't get the AP TC to add on to an existing network in initial set up as , even though the option is available, the Airport Utility (6.3.2) doesn't seem to keep it selected, and wants to create a new network.
When I create the new network, my internet connection drops out, even though the modem indicates that it is connected. I then edit the internet connection in AU by telling it to extend the existing network (add in the SSID etc) which picks up the internet connection again, but then the Airport TC drops out, and all I get is a blinking amber light and a message saying no configured Airport Base Stations detected, continuing to search.
I have no doubt that it is something I am or am not doing. I have soft, hard and Factory reset the TC, reset the modem, changed cables, pretty much everything my tiny brain can think of.
I have looked through the support pages and follwed thier advice, with no luck.
Help please.

I can't get the AP TC to add on to an existing network in initial set up as , even though the option is available, the Airport Utility (6.3.2) doesn't seem to keep it selected, and wants to create a new network.
"Add" would be used for a wireless connection....and you indicate that you are using Ethernet to connect the existing modem/router and Time Capsule together....so the correct setup would be to create a new network using the exact same wireless network name and password as your existing network.
Connect an Ethernet cable from one of the LAN <--> ports on the current modem/router to the WAN "O" port on the Time Capsule.
Here, I am assuming that the TC will be located at least a room or two away from your main wireless router. If it is located any closer, there will likely be wireless interference issues between the two routers. The wired connection between the modem/router and Time Capsule must be maintained.
AirPort Utility will suggest a setup that looks somewhat like this.....except you will see a Time Capsule instead of an AirPort Express as illustrated below:
Network Name would be the name of your existing wireless networik
Base Station Name is a device name that you want to call your Time Capsule
Password is the wireless password of your existing wireless network
Verify confirms that password
Click Next and the setup utility will auto configure things for you in a minute or two
When you see the message indicating Setup Complete, click Done and you should have a green light on the TC.

Can I connect my Airport Extreme Time Capsule via ethernet to another router (non-Apple)?

I've been trying to figure this out for a few hours and have gotten nowhere. I have an Archer C7 AC1750 router set up in my office, connected to my Zoom 5341 DOCSIS 3.0 Modem; this has been my main router and has worked fine. I have moved some things around and now have my PS3 and PS4 in my master bedroom but can no longer hook them up via ethernet to the Archer C7. I have run ethernet through the attic into the master bedroom and want to use my Airport Extreme Time Capsule as a way to hook up the consoles via ethernet. If I can use the Airport Extreme to extend my wireless network back to the bedrooms that is even better, although that is an afterthought.
I am not sure what the settings need to be to make this happen. I have searched and tried a number of things but have not found a working solution.
Any help would be greatly appreciated.

Please start over with a default reset on the Time Capsule. This will not affect any of the stored data that you might have on the drive. You can use the same device name and password that you used before if you wish.
Power up the Time Capsule for a few minutes. Then hold in the reset button firmly for 10 seconds and release. Allow a full minute for the Time Capsule to restart to a slow, blinking amber light.
Make sure that the Ethernet cable connection from the Archer router connects to the WAN "O" port on the Time Capsule
Open up AirPort Utility
Click on Other WiFi Devices
Click on Time Capsule xxxxxx
AirPort Utility will suggest a setup, which you want to ignore
Instead, click the Other Options button
Select the Create a new wireless network setting and click Next
In the Network Name box, enter the exact name of your Archer wireless network
In the Base Station name box, enter a name that you want to use for the Time Capsule device
Uncheck the box to use a single password
In the Network Password box, enter the password for the Archer wireless network
Verify on the next line
In the Base Staion box, enter a password that you want to use as a device password for the Time Capsule
Verify on the next line
Click Next and wait while the AirPort Utility creates a network
Ignore the step about unplugging the modem and click Next
Do not enable the Guest Network option and click Next
Wait while the network is being set up. When you see the message that the wireless network is available, click Done
The Time Capsule will now appear in AirPort Utility with a blinking amber light
Click on the Time Capsule icon, and then click on Edit in the next small box that appears
Click the Network tab at the top of the window
Change the setting for Router Mode from DHCP and NAT to "Off (Bridge Mode)"
Click Update at the lower right and click Continue
Wait a full minute for the Time Capsule to restart and you should have a green light
It would be an excellent idea to power off both the Time Capsule and Archer router now, wait a minute, then start the Archer router and let it run a minute. Then, start the Time Capsule up and give it a minute
You should be all set. The Ethernet ports on the Time Capsule are now operable and the wireless network has been extended using AES encryption.

Using time capsule to share internet connection with a pc via ethernet

Hi,
I've recently acquired a time capsule and was wondering if i could use it to share a wireless internet connection via ethernet to my non-wireless (windows 7) pc?
My current situation is that i have a wireless modem/router that shares my internet connection wirelessly with my mac mini.
I have a pc without a wireless card that i want to connect to the wireless network so i was wondering if it was possible to attach the pc and the time capsule with an ethernet cable, then connect the time capsule to the wireless network and share the internet connection with the pc.
Can anyone tell me if this is possible, and if so how?
Thanks

Welcome to the discussion area!
IF...your wireless network is now being created by another Apple "n" router like an AirPort Extreme, AirPort Express or Time Capsule, it would be possible to do what you want to do.
But the Time Capsule would not be compatible for what you want if your wireless is created by another manufacturer's router. The Time Capsule could "join" this wireless network so that backups would occur over wireless. However, when the Time Capsule is configured this way, the ethernet ports on the device are not active, so this would not help with the ethernet connection that your computer needs.
A new AirPort Express 802.11n would do what you want. It has the capability of joining virtually any wireless network and the ethernet port can be enabled using the ProxySTA feature, so it would work for your purpose.

Self-assigned IP !!! Can't connect via Ethernet

Hi all,
This is my problem:
- Now every time I connect my MBP (running 10.6.4) to my hall's network (staying on campus, in uni) it appears as "Self-assigned IP" and cannot connect to the internet for the Ethernet. It suddenly happened a few days ago and I have no clue what caused that
- Airport's working well
- Using Windows on Parallels and can still connect to the Internet despite that the Mac OS X does not at the same time, my friends' laptops have no problems as well
- Tried taking the IP, subnet mask, router( I suppose in Windows it is called Gateway ) details and typing in manually for the Ethernet settings on OSX but still cannot connect to the Internet. The status is Connected and "Ethernet is currently active and has the IP address 137.xxx.xx.xx."
- When I bring my laptop to a different place and connect via Ethernet, it works well, too, I just leave the setting to be "Using DHCP"
I've seen that lots of people have met this issue, also loads of advices have been given:
- reset the router ... --> I'm connecting to the hall's network, so that's impossible for me to do
- sudo ipfw list , sudo ipfw flush .. --> nothing changed afterwards
- someone suggested uninstalling any VMware --> tried uninstalling parallels desktop and the problem's still there
- untick the "Use Passive FTP Mode" for ethernet --> no difference
- Security settings ,Firewall --> firewall was even off when the issue 1st appeared
So ANY SUGGESTIONS PLEAAASSSSSSSSSEE !!!! I'm sick of having to turn to Windows just to access the internet
Thanks in advance

I'm wondering what it means by "move" here :? Is that "copying and then delete the original" :??
A "move" operation is normally considered equivalent to (although more efficient) than "copying and delete the original". Just drag the folder out of its original folder and onto the Desktop, which will make it be no longer in its original folder.
I've seen others post advice about moving out specific files in that folder. That probably works just as well if not better (as it leaves in place other files not involved in networking), but I haven't spent the time to determine just which files should be moved.

Connecting Airport Extreme N to Time Capsule via ethernet to extend wireles

Hi, I currently have 2 Airport Extreme N and a Time capsule and would like to connect all three together. I am planning to use the time Capsule as the router and then use the other airport extreme to extend the wireless network. I am planning to have ethernet connection between the three devices ie Airport extreme N (A) is connected to time capsule via ethernet and airport extreme N (B) is connected to time capsule via another ethernet.
I have tried the Extend Wireless network option to connect them, but that seems to generate so much traffic between the airport extreme N and the time capsule that the network is not usable. I have also tried using WDS but that didn't seem to work.
The three wireless networks have some areas of overlap but the signal is weak which is why i prefer to link them up with ethernet.
What is the best wall to configure them? should I set them up so that they're each creating a wireless network but with the same name? Or is there a better solution? Thanks!

It seems to me the easiest way is to have the Airport Extreme connect to internet using Ethernet, using DHCP and the Connection sharing in off (bridge mode) and then create a new wireless network with the same name... Is that correct? I have previously ran the apple wizard and it did something weird with the network and then both the time capsule and the airport extreme are serving out IP address and both of them have the same IP address 10.0.1.1. which then messes up everything...
Any ideas? thanks!
