Airport Express with linksys Router EA7500

I am trying to extend my WiFi Signal using my two airport Express connected to Linksys router via Wifi.

Unfortunately, that won't work, since Apple has designed their "extend a wireless network" feature to only work with other Apple routers. The Express cannot wirelessly extend the signal from a third party wireless router.

I used Airport utility selected add new existing network and it said successful and shows green light but my wifi signal is the same. Very low.

The AirPort Express been set up to "Join a wireless network". It can be used for AirPlay or to connect a remote USB printer, but the AirPort Express cannot "extend" or "repeat" the wireless signal in any way when it joins a third party wireless network. That's why you see no signal improvement over the wireless.

Can I connect the linksys router EA7500 with Airport Express?

Yes, but the AirPort Express must connect to the Linksys router using a permanent, wired Ethernet cable connection. If you cannot run the Ethernet cabling, you might want to take a look at Ethernet over Powerline adapters to try to send an Ethernet signal over the existing AC wiring in your home.

Already answered this for you above. Here it is again:

the AirPort Express(es) must connect to the Linksys router using a permanent, wired Ethernet cable connection. If you cannot run the Ethernet cabling, you might want to take a look at Ethernet over Powerline adapters to try to send an Ethernet signal over the existing AC wiring in your home.

Post back when you have the Ethernet cabling installed that will run from each AirPort Express location back to the Linksys router and we'll go over the setup. You can run Ethernet cabling up to 300+ feet, so you should not have any problems with signal loss.

Now last couple of months the Airport Extreme restarts when I start playing a video or download some heavy files. hence I bought a Linksys EA7500.

Sorry, I am confused. This information sounds as if you are using the Linksys as your wireless router, not the AirPort Extreme.

The AirPort Extreme must be the device that is providing your wireless signal on the network if you want the AirPort Express(es) to wirelessly extend that signal.

If you power off both AirPort Express devices, can all of your devices connect to the wireless signal from the AirPort Extreme and get a good Internet connection that way?

If they can, then I'm not sure why you need the Linksys router, since you now have two devices both providing a wireless network signal. You will have to reset the AirPort Expresses and set them up again to extend the AirPort Extreme wireless network. The Expresses cannot extend the signal from the Linksys router.

If you want the second express connecting by wireless to the first.. then the automatic setup should do it without any intervention on your part.

However it is much better to use ethernet.. or use none more wireless AP than absolutely necessary.. simply adding another express because you have one is pointless.. and will actually cause things to slow down not speed up.

In the end if the wireless still has penetration issues.. more ethernet is needed.. and higher power AP with AC wireless.. not the Express tiddlers.

Let me see if I can help.

I guess first thing I would do is warranty return if your Time Capsule (TC) is less than 3 years old.. normal warranty for one year.. and applecare on computer or ipad or appleTV for another 2 years.. is that a possible??

If out of warranty.. plug the time capsule into EA7500 by ethernet and set it in bridge mode.. wireless off if you think it is a problem.. but I would test with wireless on as well.. but it is better if the TC is located at the other end of your house where you need better wireless. The Express can also plug into the TC and simple setup as wireless access.

The auto setup on the Mac or ipad airport utility should handle it. Give it a go and post screenshots.. I cannot help much without screenshots if you run into trouble.

1. Should I connect the cable from linksys to WAN port or ETHERNET port on Airport Express?

WAN for setup.. later on it makes no difference.

2. On Airport Utility - Do I need to setup a new connection?

Yes. exactly as follows.

1. Click on Other Wi-Fi Devices (1) then click on your Express.. I am using an extreme.. but same thing.

2. On the first screen that comes up choose other options in the lower left corner..

3. Create a new network.

4. Fill in the names..

Same wireless name as your Linksys if you want it roaming.. up to you though if you want the airports on a different name. Give same password if you use the same name.

5. Hopefully it will complete successfully.

6. You can then open it in the airport utility and click the icon.. it will give you a summary page.

Voila.. done.

Suggest that you get the first Express up and running correctly. If you followed the steps that LaPastenague provided, the AirPort Express will be automatically set up in Bridge Mode, meaning that DHCP and NAT are turned off.

When you are ready to configure the second Express, temporarily move it close to the first Express

Power up the second Express for a minute or two, then hold in the reset button on the back of the device for 7-8 seconds

Release the reset button and allow a full minute for the Express to restart to a slow, blinking amber light status

On the iPad....

Go to the Home Screen

Tap on Settings

Tap on WiFi

Tap on AirPort Express under the listing of Setup New AirPort Base Station

The setup 'wizard" will open up and suggest that the second Express will extend the network of the first Express

Enter a device name for the Express

Tap Next

The "wizard" will set up everything for you automatically and correctly.

When you see the message of Setup Complete, tap Done

Now move the second Express to the area where it is needed. The more that is has line-of-sight with the first Express, the better the network will operate

Before we get started, I need to clarify some things.

1) I understand you have the current versions of the AirPort Express.....the one with 2 Ethernet ports, correct?

2) I understand that you will be permanently connecting the first AirPort Express back to the Linksys router using an Ethernet cable, correct?

3) I understand that you want the second AirPort Express to connect to the first AirPort Express using wireless, correct?

4) What device will you be using to set up the AirPort Express? A Mac? PC? iPhone / iPad? If you have a Mac, I assume that it is running a current or recent version of the Mac operating system, correct?

5) You are asking about the AirPort Extreme. If you have turned off the WiFi on the AirPort Extreme, how do you plan to use the AirPort Extreme on the network? What will it do? Frankly, if you have turned off the WiFi on the AirPort Extreme, and you are using the Linksys as your router, I do not understand why you even need the AirPort Extreme at all.

my Airport Extreme (Wired - with WiFi Off)

This confirms that the AirPort Extreme is not producing any wireless signal at all.

Since the AirPort Extreme is not producing a wireless signal, there is no signal for the AirPort Expresses to pick up to extend. They cannot extend a wireless signal that does not exist.

5. Airport Extreme has 2TB drive. I want to access those files. I have connected that to linksys through LAN ports.

Is your airport extreme 2TB hard disk plugged into USB? Or is it internal.. in which case it is not an airport extreme.. it is a Time Capsule.. which confuses lots of people. Apple made two similar products.. current model tall AC wireless Extreme and TC are externally identical.. just the TC has internal hard disk.

Airport Extreme 2TB - I have this - Please check the link: https://goo.gl/4XDoaz

Not an AirPort Extreme. The link says AirPort Time Capsule.

You are going to have to stop providing incorrect information.
