Roaming Network / IP Issue

It would be much better if you could convince your ISP to allocate more IP addresses to your network. There is likely a setting on your ISP provided modem/router that will do this.

Otherwise, you will have to try to run one of your Apple routers with a setting that "breaks the rules" as far as basic networking is concerned.

As such, there are no guarantees that this will work.

Do you want to try to do this?

If yes, we are going to need to ask more questions to understand how you have your network set up at the present time. You will need to be very patient with this, as some experimentation will likely be required.

Which device....the Time Capsule or the AirPort Extreme....is connected to the Ethernet wall jack?

If you open Macintosh HD > Applications > Utilities > AirPort Utility, can you "see" both the Time Capsule and AirPort Extreme?

Which device is connected to the Internet in the graphic?

TC is connected to the ethernet wall jack and is being treated as the the 'primary' router.

Thanks. It is not acting as a router at the present time.....it is acting as a "bridge".

AE is also connected to a wall jack in another room but I THINK i have created a roaming network by first setting up the AE next to the TC before moving it through to the other room.

We're not to the AirPort Extreme yet, but if you want to configure it as a roaming device....connected by Ethernet....you will need to plan to run an Ethernet cable from one of the LAN <-> ports on the Time Capsule to the WAN port on the AirPort Extreme. You will not be able to use the Ethernet port in the other room if your ISP service is delivered to that Ethernet port.

If the distance is not too great or there are not a lot of obstructions in the signal path, it might be possible to configure the AirPort Extreme to extend the signal of the Time Capsule using wireless only.

If that is not possible, then you might be able to send an Ethernet signal from the Time Capsule to the AirPort Extreme using a pair of Ethernet powerline adapters.

You really have two issues here.....one is whether or not the Time Capsule can be configured (with errors) to be the main router. Assuming that this works....as I said there are no guarantees.....then the AirPort Extreme connection will need to be thought out.

If you want to proceed with the Time Capsule, then you should set the AirPort Extreme aside and power it off until you know whether the Time Capsule will work correctly when it is set to share IP addresses.

Do you want to proceed with only the Time Capsule at this time?

OK, thanks for the info. Let's tackle the TC first and see if that will work. In case we need to start over and re-configure the TC or the AirPort Exreme, I assume that you know, or have written down the name of the wireless network, passwords, etc.

Use your Mac that shows that the TC is connected to the Internet. I assume that it still displays this way. If not, power off the TC and wait a minute, then power it back up to make sure that the Mac can "see" the TC and that the TC is connected to the Internet.

We are going to try a "shortcut" first to try to avoid completely resetting the TC back to factory default settings and then setting it up all over again.

Open AirPort Utility on the Mac

Click on the TC icon, then click Edit in the next small box that appears

Click on the Network tab at the top of the window

Change the setting for Network Mode to read DHCP and NAT

Click Update at the lower right of the window

Wait a minute for the TC to restart. The amber light will be flashing slowly at this point

When you look at or click on the TC in AirPort Utility, there will be one or more amber dots with an "error" next to the dot. Post back with the "error" that you see.

The TC should supply IP addresses for up to 50 wireless devices and another 150 wired devices in that setting. I assumed that the TC was set for Bridge Mode.

Check the following setting in AirPort Utility:

Click the Network Tab again and then click Network Options at the bottom of the window.

Check the setting for iPv4 DHCP Range. It should read 10.0.1.2 to 200.

If that is the setting, the TC is providing IP addresses for almost 200 devices. You do not have an IP issue here as far as the number of device.

Instead, your Internet Service Provider has almost certainly placed a strict limit on the bandwidth of your Internet connection.

What is happening is that the extra devices you are trying to connect are requiring more bandwidth than the service allows for your connection. Ask them if they can provide you with more bandwidth.

Otherwise, I am afraid that you have done all that you can do from your side of the Internet connection.
