How to setup a network with airport cards

I have an unusual lapse in figuring out how to set up a network with an iMac and iBook both with 10.4.7. I have an Airport card in both machines after my Airport base stopped working properly. I have Comast DSL.
The iMac is working fine and connects to the 'net but the iBook does not and also does not connect to the network. I cannot seem to grasp the many variations of the network options; I'm not a novice user but the network aspects fly over my head.
Is there any resource available that can explain thoroughly how to set up the network, or perhaps give me a "recipe" for setting up the Network and Sharing options? I've tried to find this info to no avail. Right now I cannot join the iBook and I know there must be an easy way to do this.
Thanks in advance.

How to setup a network with a time capsule, airport extreme and an airport express?

Hello.
First I want to make it clear all my knowledge off wireless networks is going on forums on the internet, before a couple of months ago I didn't realize wireless networking was so intricate so forgive my lack of experience.
I just bought a time capsule (today, 4th generation), I have an airport extreme bought in January 2011 (they just got refreshed so mine is now one generation old) and the same with my airport express (bought in January).
I originally bought the airport extreme and setup a wireless network using the dual band setup. I have no issues with the 5ghz network and most of my devices run on wireless n so I had no issues with them. my only two wireless devices that can not use the 5ghz network is my iPhone 4's which use wireless n but it has to use the 2.4ghz signal. Problem is in my apartment I am bombarded with other peoples 2.4ghz networks so my signal is terrible 10-15 feet from the airport extreme. Near my extreme I am getting signal ranges around 15mb to 20 mb. When Im about 15 minutes away in my bedroom (so one wall in between) my signal plummets to 1-2 mb. sometimes as low as 0.17mb which is not good. I got the airport express to extend my range and placed it in my bedroom. . After setting up the airport express the signal still was terrible. I researched and realized that if the signal strength ***** then the airport express cant boost the signal as much which makes sense in hind sight. I then researched setting up a roaming network or a WDS network. Per research a WDS network was not recommended b/c I was not using a wireless g network. I attempted to create a roaming network and then realized that you can not use an airport express in a roaming network. This has led me to now buy a time capsule.
First, in my setup do I or should I have the time capsule as the primary? I believe its more powerful than the airport extreme but Im not sure if that matters in a network that is distributing wifi from ethernet (thats how I am connected the extreme and the time capsule)
so can I do
cable modem ETHERNET Airport extreme(in the living room where its always been and works great in that immediate area) (3rd generation) ETHERNET Time Capsule(in the bedroom where I usually get poor signal) (4th gen) and then an airport express connecting to the 2.4ghz signal in the bedroom where the time capsule also is EXTENDING the wireless range?
or should it be the time capsule first bc its more powerful?
I tried setting up this setup and everything is green but I don't know if what I am doing is actually working on full cylinders b/c I am confused on some aspects. mainly on the airport extreme which is the primary device I have under the wireless tab selected create a wireless network and on the time capsule it also is on create a wireless network with the network name being exactly the same. Should it be changed to extend a wireless network? and then bridge mode? Should I have different channels for the different devices that are on 2.4ghz?
I am open to hear ANY suggestions, or ideas to improve my setup. PLEASE PLEASE HELP!!!!!!!, lol its been 5 long months of poor internet in my bedroom where my wife has her setup with a roku box and wifi tv (I have those hardwired for now) but mainly for her iPad and iPhone b/c its so bad sometimes she has to turn wifi off and use 3G. I have same issue in my bathroom, sometimes Im getting decent signal and sometimes its so bad I can't open the link on an RSS feed in safari which I have to assume doesn't require that much bandwith?
I have no wireless g devices. The only device I need 2.4ghz for is my iPhone 4's but they both use n also. All my other deivices connect on 5ghz and my 5ghz network is decent, a lot better than the 2.4ghz network atleast.

You wrote so much that I find it hard to address all your concerns. However, here are some thoughts:
1) I'd configure the Time Capsule as the "main" router, connected directly to your cable modem. Configure it to "create a wireless network" and to "Allow this network to be extended". Configure the other devices to "Extend a wireless network".
2) Put any device that's extending the network half way between the main router and the wireless clients. If the signal from the main router is weak at the cllient's location, then the extending device will also receive a weak signal.

How to setup wired network with G4, MBP and PC

Sorry to ask a bit of a stupid question here, but I've never had to network machines together so I'm starting from a knowledge level close to zero.
Situation. Old G4 (733) and new (intel) Mac Book Pro in one room. New PC (Dell) in another room with a wired router connected to internet. PC is also connected to a laserprinter. Hard wire ethernet cable running between the rooms to connect either the G4 or the MBP to the internet. Both the G4 and the MBP have only one ethernet connection. MBP is wireless, as is the PC. The G4 is not.
First off, I'd like to network the MBP and the G4. I believe ethernet is the best way to do this, but if I do that, how would I then connect to the internet? Would I just have a second router in the Mac room with the 2 Mac's hooked up to it and the other end going back to the router that's connected to the internet? I'd rather stay hard-wired than go wireless if at all possible. I do most of my internet work through the MBP, but some must be done through the G4, ie software updates, as the G4 has a lot more programs on it.
Second question, how would I then network to the PC in the other room? It would be nice to move files, photographs for instance, between the Macs and the PC. I'd also like to access the lazerprinter which is in that room, connected to the PC.
Hoping this is a simple question with a simple answer.
Thanks!

Hi-
Welcome to Discussions!
What you are describing is all possible, but, I am going to assign you some reading. This way, you'll be able to deal with your own particular needs, like a Pro.
The following will get you up to speed on networks, and various hardware needed:
http://www.atpm.com/network/setup/index.html
http://compnetworking.about.com/od/homenetworking/HomeNetworking_Setting_Up_a_HomeNetwork.htm
http://www.apple.com/support/tiger/network/
Adding the PC into the network has some special considerations. the following sites have good info for setting up such a network:
http://www.mac-connect.com/
http://www.apple.com/business/mac_pc/tutorials.html
For my needs, I have a switched ethernet network. All computers are connected to the switch, as is the modem, by ethernet cable. This allows computer to computer networking using AppleTalk. With the same cabling and switch, the computers are all able to connect to the internet using DHCP, or, one at a time using PPPoE.
These are all Mac's, but, with some setting adjustments, a PC can also be placed in a similar network.
As well, adding a wireless connection for one computer is possible. This would require a wireless base station to be connected to the switch. The wireless capable computer would then be able to enter the network, and vice-versa. Of course, the settings for all the hardware and software are the key. The settings can have variables, depending on what is connected, and how the connections are made. Another variable is your router/modem, and your internet service providers policies on multiple connections.
Adding the printer depends on the capabilities of the printer. Often, it is only possible to share a printer through a computer. A network capable printer can be connected to the switch, directly, or to a wireless base station, and then shared by all on the network.

How to setup wireless printing with AirPort Express?

Hey, I just bought a AirPort Express today and I can't figure out how to setup the usb wireless printing. Could someone explain in detail on how to do this? Thanks-Michael
I have a Windows 7 64-bit PC and a Hp Deskjet F380 USB printer.

Download the install Bonjour Print Services for Windows v2.0.2
Run the program. Hopefully, your printer will be recognized.
If it is, "install" the printer and try to print.
Keep in mind that if you have an All-in-One type of device, that only the print function will be supported.
Advanced features like copy, scan, maintenance, etc are not supported. You will need to connect the All-in-One directly to your PC if you need those services.

How to setup a printer with Airport Extreme + Express Network

Ok so here's how things are setup. I have an Extreme connected to my cable modem creating the wireless network. I have a PC that doesn't have a wireless card, so I setup an Express next to it. The Express takes in the wireless signal, and the PC is connected to the Express through ethernet and has a successful connection. Next I want to connect my printer to the USB port of the Express and share it over the network. It doesn't work plug and play. From the Airport utility, the express recognizes the printer, however, the computers on the network do not see it. Can this be set up to work? If so, what am I missing?
Thanks

If you are on PC's, you will need to download the bonjour for windows.
just google it.

How to configure home network with Airport Extreme + D-Link DIR-665

*hello everyone,*
*I had these two working fine together until the D-Link took a dump the other day. No explanation. Just stopped working until I reconfigured everything.*
*Which then led to my Airport Extreme being unable to connect to the network at all, much less the internet...*
*My home network is set up like this:*
*Optimum Cable*
*Motorola Surfboard modem --> D-Link DIR-655 (via ethernet)*
*- Provides wifi and ethernet connections on one side of my house*
*DIR-655 --> Airport Extreme (via ethernet run to other side of house)*
*- Provides wifi and ethernet connections on the other side of my house*
*My MBP won't connect to anything other than my AE running N, so I have that set up primarily for my MBP over wifi, while feeding an ethernet connection to a Netgear router running B/G, for my iPhone and other devices.*
**So here are the relative details:**
*I decided to start fresh and do a factory default configuration with my Airport Extreme. My working system from earlier was essentially it's own wifi network, but the airport utility 'insists' that I need to run my AE in bridge mode. I've tried that, but I can't get online. I can see my shared connections, so something's getting through, but I cannot connect to them, in addition to being unable to get online.*
*I'm not really sure how to best illustrate this problem, so I've ran through the process again and jotted down a few notes. Excuse the rambling nature of my narrative, this is a 'blow by blow' account of the Airport Utility setup process:*
Airport version 7.4.2
IP address 192.168.0.192
router address: 192.168.0.2
Configuring over Airport connection.
- I want AE to join my current network
-.. connect AE to my network using ethernet to extend or create second network
- select device AE will connect to using ethernet - DIR-655 network (displayed w/ airport icon?)
- create an additional network (through ethernet)
AE updates..
- problem 1 of 1 : unsecured wireless network
wpa wpa2
Bridge mode or share a single IP address using DHCP
selected bridge mode
results: AE has green light, airport utility is satisfied but no connection to network is possible. Shared connections are visible, but unable to access
next try:
manual setup
Wireless mode: create wireless network
radio mode: 802.11n only (5 GHz)
channel: auto
wireless security: WPA2 personal
(bridge mode still active)
(this is the exact setup that worked for years before..)
updated…
AE light is green, but no connection to internet or shared connections (though visible)
back to airport utility
manual setup:
internet menu:
connection sharing: share a public IP address
update
--> 2 problems
DHCP Beginning address: 192.168.0.2
DHCP Ending Address: 192.168.0.2
chose 'assist me'
(now one shared connection to Mac Mini becomes active? Had selected it earlier. Able to browse folders, but not share screen)
AE refreshed now with amber light, with reported problems
Problem 1 of 2: Internet Connection
Your Apple Wireless device does not have a valid IP address. Make sure your Apple wireless device is connected to your broadband modem or local network… etc
- changed IP address to match router IP address (?) Utility goes on to next problem
Problem 2 of 2: Conflicting DHCP Range
This Apple wireless device rejected a DHCP address in the same subnet as its internal DHCP server. You should probably switch your Apple wireless device to be in bridge mode. If you still want to be using DHCP and NAT to share a single IP address, you should change your DHCP range.
- maintain selection: share a single IP address using DHCP and NAT (utility forces you to: ignore; skip; or select bridge mode - which doesn't work..)
- chose 'skip' for problem 2
- updated AE..
New problem:
Problem 1 of 1: Double NAT
This Apple wireless device has a private IP address on its Ethernet WAN port. It is connected to a device or network that is using Network Address Translation (NAT) to provide private IP addresses. you should change you Apple wireless device from using DHCP and NAT to bridge mode.
- selected Bridge Mode
updated AE…
"Setup Complete!"
Unable to connect.
** At this point, I am still able to see my shared connections, and while iTunes is open, I can play my shared library that is on my Mac Pro, which connected to the DIR-665 via ethernet, through yet another D-Link router (DIR-615)! I am still connected to the Airport Extreme via wireless, so the system is working, to an extent.*
*So I'm not sure what to do. How can I remedy my IP address issue? Bridge mode doesn't work (as far as I've experienced), so I'm struggling with my DHCP settings..*
*Thanks to anyone who has any suggestions!*

Hi Preston,
I would recommend not starting the numbering scheme for the IP addresses using a '0'. Yes the range is 0-255, but some numbers are reserved, and not generally good practice.
Also, assuming you have reset all factory defaults, start anew and have the modem --> router using NAT for dynamic IP addresses --> (other side of the house) Airport Extreme --> not a NAT configuration, but you need a simple switch. Do not use the NAT capabilities on this one. Maybe, just maybe the computer will work now. This will eliminate your double NAT and also help (hopefully) with the D-Link.
Sorry I cannot help more, I do not own any of the products you talk about, however I have networking experience. Hope it helps.

How do i use my time capsule and extend the network with airport express

I have a new iMac and Time Capsule, how do i extend the network with airport express. My time capsule does have a guest net work, and logins and passwords? I am no computer person. So for me it would have to be spelled out.

Use the search as this has been done to death ..
Bob Timmons is the expert on this.. look at his answers here.
https://discussions.apple.com/thread/4274187?start=0&tstart=0
https://discussions.apple.com/message/21856077#21856077
This has been automated in the v6 utility. I am used to doing it manually in v5 utility which is also fairly easy.
Apple doco is also good to read.
http://support.apple.com/kb/HT4145
http://support.apple.com/kb/HT4259
Note.
You cannot extend the guest network unless everything is up to date 7.6.3 firmware. And that is only with the TC as the main router in the network.
All apple routers can be configured as the main wireless or as the extend wireless.. so don't worry if a post uses express or extreme or TC.. they are for wireless, the same thing.

Is this type of set-up possible - private and public network with Airport

We have an office network with Airport. We have internet with a cable modem with routers plugged to it. The network is not now shared with anyone outside the business.
But would it be possible to add a public component to our setup that would give others access to the internet but never, never, never allow them to enter/see/ mess with the private side?
Tim

Sorry to intrude, I came across this thread while I was looking for some other information and thought that there needed to be a point of clearification to identify some major security vulnerabilities.
With the current config, Cable Modem->Wan port of Router A->Router B plugged into LAN port on Router A
1. Traffic from Router A would see all traffic sent from router B out to the internet, if I was able to sniff the traffic on router A then I would see everything that router B was passing to the internet...not good idea if Router A is public, (traffic would not be encrypted since this is a hard line pass to the cable modem).
2. Router A will always be able to see the interface of router B (have to have it this way to perform the passing of IP traffic from one router to the other.) This means that router B will be open for brute force login attempts and any other vulnerabilities that the router might carry, again since this is being accessed from a publicly accessible network it would be hard to stop from happening in todays world.
3. Router B subnet - If you NAT all the IP's behind router A on it's on subnet (which would include Router B). Uunless router B truly has two interfaces (internal and external) you would not be able to use different subnets and expect to pass traffic all the way to the cable modem because it would not know how to get there.
Again, this post is not meant to cause annomosity, it is to help educate.
I personally think that the safer bet is to get a second hi-speed connection, physical seperation in this case is the best way to go, saves you the worry of getting attacked or snooped on, and keeps your private information safe from the public...unless that is something that you are willing to risk sharing.

How to setup private network in oracle rac

Hi all,
Iam trying to setup oracle 2-NODE RAC ,
now i stuck in setup private network..
how to setup private network, what i have to do for that.
please help us provide step by step process

The loop is nothing but a network cable connecting two nodes on same port with a private IP address (something like 10.0.01 and 10.0.0.2) which is not accessible by any other machine in the network (except 2 nodes obviously ).
Note that cross over cables are not supported for the Cluster Interconnect. And cross over cables limit the cluster to only 2 nodes, which may not be enough for many RAC deployments.
Cheers,
Brian

How can I change my internal airport card from G to N ???

I just want to know how can I change my internal airport card from G to N and how much that cost ?

The description of your machine (2 ghz MacBook) can describe maybe three different generations of the original polycarbonate MacBook.
If your machine is a Core 2 Duo MacBook that came out before the late 2007 models - $2.49 Canadian. It's all done in software, and won't work on the Core Duo models. The equivalent enabling software also comes on a disc if you get the latest 802.11n Apple AirPort Extreme or AirPort Express base stations.

Before you buy, you can check to see if your machine already has it.

How do I create an imac base station wireless network with Airport?

I just got the Macbook Pro and have a G4 imac with an airport card installed. I'm trying to create a network using my imac as the base station - any suggestions on how to do this?

Thanks for your response!
Unfortunately, it doesn't seem to be working. I was following the excellent directions in the attached PDF, when, on page 11 (or was it 10?) the directions just stopped at number 3. It seems there need to be more steps...
http://manuals.info.apple.com/en/DesigningAirPortNetworks.pdf
I've followed the step-by-step given on the link you shared - which matches what is found in the PDF. I've done all of that for my imac. However, I'm not sure exactly what settings need to be set on my macbook pro to get it to connect to the internet. I'm close - so close! - as the airport in the menu on my macbook shows 4 bars - but when I try to connect, nothing.
So frustrating! Any help would be golden...
