Airport express and comcast telephony modem

I just had Comcast setup cable modem/telephony in my new home.
Technician set up and was only able to get the internet to work if plugged directly from modem into network card on the PC notebook.
I replaced that cable with the airport express, got a green light. both the PC and the mac found the wireless connection and I had internet access from both.
About 2 days later I lost my internet connection. Both machines still find the wireless and report strong connection. but no browser connections.
Interestingly enough, the PC wanted to download some MS updates and was able to do that, but still no connection via IE, Safari, Firefox.
Talked with several techs from Comcast, finally last night I just go the one direct connection with cable working again.
Any other experiences like this??? I want to use wireless and just need to know what the best way to proceed may be.
Thanks,
Bill

Alexkywalker, Welcome to the discussion area!
Whenever you switch the Ethernet connection from a cable modem from one device to another you need to power down the modem. This will force the cable modem to forget the device it was talking with. The cable modem will then discover the new device and communicate with that.
BTW, the AirPort Express (AX) has an auto-sensing Ethernet port and therefore will work with any type of Ethernet cable.

Can u run Airport Express and a wireless modem together?

Can u run Airport Express and a wireless modem together at the same time?
I'm using AE purely for music distribution and have just bought a wireless modem for the internet (not a AE). However I can now only select either the AE network, OR the wireless internet network (it's BT HomeHub). Hence I can either play music or use the internet, but not together!
Any ideas anyone..??
Thanx
David

You should configure your AirPort Express (AX) to join the wireless network provided by the modem. The instructions are in KB 302153, AirPort Express: How to join an existing wireless network in client mode.

@ Airport Express and BEWAN DSL MODEM : no internet ..why ?

Hello,
I connect a BEWAN ADSL Modem to my Airport Express and create a Airport network to have internet access for my Ibook.
I have choose "Ethernet" for Internet access with DHCP parameter.
Here's what i see : the Bewan ADSL modem give to the airport a public IP for the ip address (that comes from my Internet Provider), a netmask and a router ip that is 192.168.1.1.
On my Ibook, i could connect to the airport (printing is ok) but I couldn't have internet access : blank page under Safari...
My Airport Express has the last Firmware....
I think is a trouble between the BEwan ADSL modem and the Airport because I have Internet access when i directly connect the Bewan Modem to the Ibook.. a routing trouble ?
Do i have to manually enter IP parameter of my Airport ?
Have you the same configuration ?
Thanks for helping me fast.

ouba john,
I'd recomend trying a reset and reconfigure. Your setup sounds pretty simple. Hold in the reset button on your AE until the light blinks, let it restart, and choose your unmodified Airport express from the drop down menu. Run Airport Setup assistant from the Utilitiies menu and try to let that program do all the tweaking for you. Once it's up and running, you can go into the wireless settings with Airport admin and reconfigure security if you wish.
This is "just give this a try" advice. It seems I've heard odd things about ADSL modems, so good luck

Airport express and comcast

Hi:
I have a i book G4 and recently got connected to comcast cable internet and although the internet works if connected directly to my computer, it does not work with airport express.
the light on the airport express is yellow?
Dont know why, it was working fine with bellsouth broadband.
would appreciate some help
Thanks

First, make sure to perform a complete power recycle of your network components.
Modem/Router Power ReCycling
- Power-off the Cable modem & AirPort Express Base Station (AX). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
- Power-on the Cable modem; Wait at least 30 minutes.
- Power-on the AX; Wait at least 5 minutes.
Setup the AX
Connect your computer directly (using an Ethernet cable) to the Ethernet port of the AX, and then, using the AirPort Admin Utility, try these settings:
AirPort tab
- Base Station Name: <whatever you wish or use the default>
- AirPort Network Name: <whatever you wish or use the default>
- Create a closed network (unchecked)
- Wireless Security: Not enabled
- Channel: Automatic
- Mode: 802.11b/g Compatible
Internet tab
- Connect Using: Ethernet
- Configure: Using DHCP
- WAN Ethernet Port: Automatic
Network tab
- Distribute IP addresses (checked)
- Share a single IP address (using DHCP & NAT) (enabled)

Airport Express and Comcast Revisited

Ok, I just can't figure this out. I have a Dell XPS PC wired using a USB 2.0 cable to a Motorola Modem on Comcast. I have plugged my AX in using the ethernet port. My laptop is a brand new Macbook Pro. I have tried most, if not all of the suggestions here and called Apple Support (which couldn't figure it out and then disconnected me) all to no avail. I'm really frustrated and have no idea what to do now. The PC doesn't recognize my AX at all and the laptop recognizes it, but I can't access the Internet (the familar complaint). Any suggestions anyone has would be greatly, greatly appreciated.

Is it possible that this is something as simple as a bad Ethernet cable?
It would certainly be worth switching the existing one with one you know works. While we're at it, let's double-check your AX's settings...
AirPort Express Base Station Setup (AX) w/High-Speed Cable Modem
Modem/Router Power ReCycling (optional)
- Power-off the Cable modem, AX, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
- Power-on the Cable modem; Wait at least 30 minutes.
- Power-on the AX; Wait at least 5 minutes.
- Power-on the computer(s)
Perform a "hard" reset of the AX (optional)
- (ref: http://docs.info.apple.com/article.html?artnum=108044)
Setup the AX
Either connect to the AX's wireless network or connect your computer directly (using an Ethernet cable) to the Ethernet port of the AX, and then, using the AirPort Admin Utility check these settings:
AirPort tab
- Base Station Name: <whatever you wish or use the default>
- AirPort Network Name: <whatever you wish or use the default>

Configuring my Airport Express and Cisco DCP3008 modem

Hi,
I have an airport express version 7.6.1
and a cisco modem dcp3008 and having issues trying to connect the two. I have called cisco and they told me they would have to reconfigure it for 60 dollars. Is there anyone that has any suggestions for how I could manually figure this out?
My cable/internet service is Charter.... and they can't do anything ha ha.

You can effectively extend the Cisco's wireless network by creating a roaming network with both routers. Note that this would require that both routers be interconnected by Ethernet. Since the Express will perform a new role, be sure to perform a "factory default" reset on it so that it will be in its "out-of-the-box" configuration.

Using Airport Express with Comcast Digital Broadband/Telepony Modem

I recently converted from Comcast's broadband modem to their combined modem for digital phone and internet. I can't connect both my G5 and the airport express to the modem simultaneously. Airport express set-up configuration shows a broadband modem with 2 ethernet ports. My modem only has 1. The modem is Touchstone Telephony modem by Arris. Has anyone made this type of connection work with this modem?
Here is my set-up:
iMac G5 connected via ethernet to telephony/broadband modem (basement)
Airport Express (basement)
iBook G4 (1st floor)
I plan to purchase an airport express base and move the airport express to the 1st floor so I can use the iBook on the 3rd floor. Before I spend the money, I want to make sure this will work.
Thanks!

Hi Soraya,
I assume your iMac G5 does NOT have a Airport Card?
It seems you will need a Router in order to get all your computers and the Airport Express to connect to the internet.

Need help with Airport Express and so on.

Ok so my main problem before getting into what I need help with here is that our MacBooks and now my iPhone 6 plus isn't staying online. Keep getting booted off and then I either have to select the network again or it will eventually go back on. If anyone has a solution or so please feel free to answer that as well. I'm running on Roadrunner with a Netgear 600 wireless router and a motorola modem. Both of which I'll leave the link to below for a better look.
My Main Question: So I'm looking at a new wireless router mainly and possibly a new modem. I know Apple products are trustworthy but how good is the Airport Express and other Airport products. Also what is the Maximum speed and Maximum data speed for the cheapest express station and if anyone knows the speeds of the other devices it would be greatly appreciated.

DSL Router to Netgear 5-port Switch and I used the switch to connect to Airport Extreme, TV, Blue-Ray DVD player and DirecTV Receiver.
The AirPort Extreme base station (AEBS) is a router so it will do what you need.
You need to reconfigure your setup. Connect the WAN port of the AEBS to the DSL router. Then connect the Netgear switch to one of the LAN ports on the AEBS. The AEBS will properly share the connection.

A Time Capsule, Airport Express and AT&T 2Wire walk into a bar...

Alas, I'm sure this question has been asked before, but my reserach keeps turning up separate answers. So I thought I'd turn to this forum for some advice. Ultimately I'm seeks suggestions on various ways to configure my network to allow easy backups, connection two rooms, and wirelessly print from anywhere.
I have a:
Time Capsule (dual band) - used for Time Machine backups
Airport Express (older)
and new 2Wire 3800HGV-B wireless modem/router from AT&T (for U-verse internet/TV)
My room configuration is:
Living room with TV, internet connected DVD player, and new AT&T 2Wire Wireless U-verse modem
Home office with 2 desktop comptuers (no wireless cards) and a USB printer.
Two roaming laptops which move around the rest of the house
The livingroom and the office can't be connected with a physical wire.
What I was hoping to do was setup my office with the Time Capsule in the office as a wired hub, and then use it as a wirelessly bridge to the 2Wire network. But as I understand it, a Time Capsule can't be used as a bridge to a non-Apple product. Please correct me if I'm wrong.
Alternately I could always get wireless cards for the desktop computers, but this leaves the printer.
I've read suggesitons of people who have used their TC as the primary router, disabling wireless on their AT&T 2Wire, and hooking the two together with ethernet. Others who just join the TC to the 2Wireness network. But really what I'm seeking is a way to join the two rooms.
Any thoughts? Am I asking the right questions or providing the right information?
Much thanks,
dana.

So I figured I'd go with an initial suggestion and attached my TC via ethernet to the 2Wire modem/router in my living room, and make the TC my primary wireless router.
Good plan
since both will be in the same room, I assume I need to disable wireless on the 2Wire
Correct
What kind of configuration do I need to do on the TC, or do I just following the wizard and select 'Extend existing network'?
You can follow the guided setup or I can give you a step by step manual setup. In either case, you will configure the TC to "Create a wireless network".
("Extend" is only used if the TC connects using wireless only....you will be using Ethernet from one of the LAN <-> ports on the 2-Wire to the WAN port (world icon) on the TC.
The guided setup will normally sense that the TC is connected to another router and suggest that the TC be configured in Bridge Mode, which is the correct setting. Otherwise, select the Bridge Mode option when it is presented.
Note....If you have a newer dual band TC, the Guest Network option cannot be enabled when the TC is configured in Bridge Mode. So, if you want a "Guest" network, maybe the 2-Wire could provide that service.
Should I attach this (via ethernet) to the TC or the 2Wire?
Pick a LAN <-> port on either one, your choice, whichever is easier
What should the AT&T DVR be connected to?
I'm not familiar with an AT&T DVR, but if it connects via Ethernet, you can connect to a LAN <-> port on either the 2-Wire or the TC
For printing, my plan is to attach the printer through USB to the Airport Express and then connect that wirelessly to the TC network (though my first attempt at this failed to connect).
Suggest that you get the TC up and working smoothly. Then tackle the Express.

How do I set up my Airport Express to my Viasat modem, which requires a DHCP connection, without getting a double NAT connection error?

I have an Airport Express connected to a Viasat 4100 satellite modem. This requires a DHCP connection and is connected to my Airport Express by Ethernet. I then have three computers (two running Mavericks and one running Lion) and two IPhone 5s and an Apple Tv on the network. If the Airport Express is set to DHCP and NAT then the network works and I have internet, but the amber light flashes and I have a double NAT error. If I use it in Bridge mode the airport express goes green but I have no internet. How can I set it up so it works properly? If anyone knows could they please give all the settings I shoud use on the Airport Express as I may have left incorrect setting on it whilst trying to fix the problem. I have checked and it has been confirmed that I cannot change any settings on the satellite modem.

Go into AirPort Utility, click on the AirPort Express, and click on the "Double-NAT" error. Click Ignore. There's nothing that can be done about the Double-Nat unless you ignore it (no harm) or contact your ISP and get them to change your Modem/Router into Bridge Mode, and even then can't guarantee that you won't get that error.
Again, best thing to do: Ignore the Double-Nat Error.

How do I install a new airport express and link a second airport express to extend the network of the first airport express?

I currently have a linksys wireless router attached to the Internet. I have an A1264 Airport Express connected by Ethernet to the linksys router. I have two network names, one for each wireless network.
I purchased a new A1392 Airport Express to replace the linksys router and join to the A1264 Airport Express, and I want to have one network name as a result.
How do I do this? I realize that I have to reconfigure the A1264 device so that it is an extension of the A1392 device.

You have a fairly complicated set up, so I suggest that it would make sense to tackle things in stages, testing each stage as you go, before proceding to the next stage.
Stage 1 would be setting up the A1392 first to the cable modem, and then making sure that everything is working correctly on the A1392 Express
Stage 2 would be adding the Netgear switch and testing each port with a laptop connected via Ethernet to make sure that everything is operational on the switch
Stage 3 would be connecting the A1264 Express and testing to make sure that it is extending the network correctly
Stage 4 would be adding other Ethernet devices to the Netgear switch and testing each one at a time before adding the next device. There is some question about whether an iOS device can print to an Ethernet connected printer....even if the printer is AirPrint compatible. You may need to connect the HP using wireless...not Ethernet....to gain full AirPrint functionality, or use another application that will allow printing like Printopia or Print Central using the Ethernet connection on the HP.
Stage 5 would be adding the printer to the A1264 AirPort Express.
You do not mention how the printer will connect to the A1264 Express, but I assume that it will be USB from your description. Most printers will work, but you really will not know if your printer will work until you try.
Remember that only printing will be supported at the USB port of the Express. If you have an all-in-one type device, scan, maintenance, and other advanced features will not be operational whent the device is connected to the AirPort Express.
If you want to print from an iOS device like an iPad or iPhone, plan to add additonal software like Printopia or Print Central to possibly allow this function. There are no guarantees here as far as the iOS devices.

Airport Express and Flashing Yellow - Please Help!

I just purchased an Airport Express and cannot get anything the status indicator to flash anything other than a yellow. I am working on a Win 7 64 bit platform and my router is Netgear N600 (model WNDR3700). The only changes I made to the router is via its utility to enter the Airport ID MAC address into the Netgears "Wireless Acces List". I deperately need input on what I might be doing wrong or need to do to my router's setup. Below are what I have tried and status info:
What I have tried:
1) Entered the AIrport's MAC address into my Netgear Router's "Wireless Access List", as well as the Ether ID (out of desperation).
2) Installed on my PC the latest version of the Airport Utility (5.5.3).
3) Plugged the Airport directly in port 4 of my Netgeat Router.
4) Changed ethernet cables.
5) Reset the Airport.
6) Rebooted the Netgear and my PC.
7) Plugged the ethernet cable from the modem directly into the Airport.
Info:
1) When the Airport is first turned on (ethernet is already plugged in), the status light turns solid greem, then goes to solid yellow for a bit, and then immediately goes to flashing yellow (approx 2 seconds between flashes) and stays that way.
2) then If I run my Advanced IP Scanner if shows the Airport, an IP of 192.168.1.20, the Airport's ethernet MAC address. The status shows "Ok".
3) If I unplug the Airport and click rescan on the IP Scanner the device remains present but the status is changed to "Dead".
Despite what I tried I get only get the yellow flashing light? Do I have a bad Airport Express or is this a failure on my part to properly set up the Netgear? Thanks in advance for any help offered.

The AirPort Express flashing yellow means it it not receiving a valid IP address. This is issued by your router.
I recommend disabling your Netgear's "Wireless Access List" until you get it resolved.
One thing that you did not mention is using AirPort Utility. You need to configure the Express using AirPort Utility for Windows. If you don't have that click here: http://support.apple.com/kb/DL1391
Read about designing AirPort Networks here: http://manuals.info.apple.com/en/designing_airport_networks_10.5-windows.pdf
A new Express creates an unprotected wireless network named "Apple Network xxxxx". You need to disconnect from your existing network and connect to that network in order for AirPort Utility to communicate with the Express. Most likely you will have to temporarily disable any and all anti-virus / firewall / security software running on your Windows to do this. If you don't see that network you will not get anywhere.
When you are finished configuring the Express in AirPort Utility, including addressing any unresolved conflicts it may report, click the button to restart it. AirPort Utility will say "the Express is now restarting" but the temporary network that it created for you to configure it will cease to exist, so just close the window. Reconnect to your usual wireless network which will now welcome the Express as a member.
After it restarts the Express should show a happy green light.
When you are finished re-enable all your Windows firewalls and AV software.

Can I use the Airport Express as a cable modem?

I am trying to set up wireless internet in my home, and I am planning to purchase an Airport Express. Can I use the Airport Express as a cable modem, or do I have to purchase a modem from the ISP and then connect the AE to the output of the cable modem?
Thanks,
Adrian

No, the AirPort base stations do not perform the functions of a DSL or cable modem, so you will still need to acquire one.
