Sudden slow wifi connection with Airport Express 802.11n

Recently, all of a sudden I noticed the speed of my internet droped dramaticlly from ~27Mbps to ~4Mbps (Speedtest.com) Comcast's blast. When I connect my laptop directly to the modem there is no problem with the speed. I tried restarting the modem, changing the channel/radio mode on the airport express, hard reset the airport epress, change the location of the airport express but nothing has changed. I notice that the speed fluctuate on speedtest.com meaning it ranges from 1-3 to 5-7Mbps. I test the speed on three other laptops but still got the same result. The only change I can think of that could effect this is the addetion of two computers to the network but I would still get the same speed when they are powered off.
Thanks

Do I have to change anything on my computers?
you use +airport utility+ (AU) (in your applications > utilities folder). launch AU, double-click on the icon of your extreme to enter manual setup, and go to the wireless tab. see this screen shot
however, before you do, i recommend you download iStumbler (does not work with Snow Leopard) or AirRadar (it has a trial period) and note the channels other networks in your vicinity are broadcasting on. change the channel of your network as far away as possible from those.
good luck !

Does airport extreme 802.11a/c work with airport express 802.11n

does airport extreme 802.11a/c work with airport express 802.11n

"You can use the AirPort Express to extend the signal provided by the new AirPort, but the Express will not extend "ac" wireless since it does not have that capability. The Express will extend an "n" wireless signal if that helps."
This is what I am trying to understand.
So AXTRM w/ sep SSID for 2.4 (b/g/n) - call it SSID1 - and 5GHz (ac) call it SSID2 - WiFi Explorer confirms AC mode on 5G.
Using an AXPRESS to extend - I have the option of SSID1 b/g/n *and* the 5GHz ac SSID2 in the pulldown (it sees both?) --> if I select SSID1, it also extends this same SSID in 5GHz (both showing b/g/n) >> so I now have 3 signals on SSID1 (XTRM 2.4G, XPRS 2.4G and XPRS 5G) b/g/n and one signal on SSID2 (XTRM 5G AC) ac
If I select the 5Ghz ac SSID2 to extend - it prompts me "do you also want to extend (the 2.4GHz SSID1)?" --> select yes and I now have 2 signals for SSID (XTRM 2.4G & XPRS 2.4G) b/g/n and 2 signals on SSID2 (XTRM 5G 802.11ac & XPRS 5G 802.11 a//n)
Is the 5G SSID2 actually being extended from the Airport Extreme to the Express?
The reason I bring this up is I am having a lot of issues since iOS8 came out (especially on iPhone 6). Everything I am reading is pointing to when people have 2 AP's set to use the same SSID. When you walk to a part of the house where 5G 802.11 ac signal marginalizes, the phone does not immediately hand over to the 5G 802.11 a/n Airport Express.
My thought was separate the SSID's but to me, if the Express can't extend 5Ghz from the Extreme, it's taking a step backwards. I am better off getting a more powerful router like an ASUS and going with one AP, drop the WiFi roaming altogether
Any thoughts?

Extending range of Linksys WRT310N router with Airport Express 802.11n

I am trying to extend the range of an existing wireless network set up with a WRT310N router with an Airport Express 802.11n - I've tried choosing both "Participate in a WDS network" and "Extend a wireless network" and both have run into problems.
Any advice would be greatly appreciated!
Thanks, Amy

amysinsh, Welcome to the discussion area!
Sorry but this is not possible.
It would be possible if the wireless network was created by another AirPort Express (AX), anAirPort Extreme base station (AEBS), or a Time Capsule.

Extend Airport Extreme 802.11g with Airport Express 802.11n

I bought a new AE 802.11n and I want to extend my network from my old Airport Extreme 802.11g. I can't figure out how to do this.

Unfortunately, the newer "n" AirPorts and older "g" AirPorts are not compatible if you are trying to configure the AirPort Express to "extend a wireless network" using wireless only.
The "extend a wireless network" function and feature is only found on newer "n" AirPorts.
If you can connect the AirPort Express to the older AirPort Extreme using a permanent wired Ethernet connection, it is possible to configure the Express to provide more wireless coverage that way.
Using an older, very difficult setup called WDS, it might be possible to configure the Express using wireless only, but the end result would be a network that provides only half the speed of your older "g" AirPort Extreme, so this is definitely not recommended due to the severe performance drop that will occur on the network.

Airport Extreme 802.11g with Airport Express 802.11n Aiport Express

I have An Airport Extreme Base Station 11g and an airport express 11g and I needed to buy another Airport Express but this one is 11n and my Airport Utility does not see it. Are these new Airport Express backward compatible? The reason is the kids X-box needs the ethernet jack that the color printer uses.
Can anyone help?
Thanks!

Thank you!
I followed your advice but so far I have been able to make some progress. I went out and bought the Airport Extreme 802.11n as I needed a router too so I like the features on the new one. So I think I have made a complex situation worse, LOL.
So far, the new airport utility can only see the new & old Airport Extreme but cant see the Express-g or express-n airports as they continue to blink amber.
What do I am I doing wrong?
thx

Need help getting LG TV wifi connection with Airport Express?

I can successfully hook the tv up to the network using the dongle PIN method on the Airport Express. It works fine until I turn the tv off. Then I have to go through the whole setup procedure again. Very frustrating. How can I get the Airport to allow the tv access when I turn the tv back on without having to do the setup again? I did not limit access to 24 hours. Not sure what I am missing. Thanks in advance for any and all help.

The dongle is the little usb device that makes the tv wifi capable, it is assigned a unique PIN that I input into the airport express utility so my wireless network will allow it access. All that works fine, but I have to redo the whole setup everytime I turn the tv off. Have you any experience with this and can offer a hint on how to allow the tv access each time I turn it on?

Lose wifi connection with airport express

Everytime I turn on the computer, there is no wifi connection. The symbol is still at the top of the screen, but is gray rather than black. I can click on it and it gives me the choice of my network or a neighbor's. All I have to do is click on mine and it connects. This is a real pain. Anything I can do

In System Preferences > Network and create a new network location.
Test by restarting the iMac.
In System Preferences > Network > Wifi > Advanced remove your network from preferred networks.
Open Keychain Access under System remove your network.
Copy /Library/Preferences/SystemConfiguration folder to your desktop as a backup. Then trash the main SystemConfiguration folder and restart the mac.
The above steps basically make the iMac's network settings default.
Join your network and remember in keychain, if prompted.
Do a restart and hopefully the iMac will automatically join your network.

Numerous problems with Airport Express 802.11n with DSL and extending WLAN

Hi all,
I have the following hardware:
802.11b/g Airport Express with firmware 6.3
802.11n Airport Express with firmware 7.3.2
MacBook Pro
iBook G4
Mac Pro PowerMac 2x450 G4
Up until now I had been using the old Airport Express as the base station connecting to my PPPoE DSL line, and it worked fine. I wanted to extend the range of this network, and got another newer Airport Express, the 802.11n model.
First I tried to use the 802.11n to connect to the Internet and the old one to extend the network. Turns out the old one can't be used to extend a network, which is bad enough, but the 802.11n one refuses to connect via DSL for more than a couple minutes, then drops the Internet connection.
So I tried downgrading the firmware to 7.3.0 and 7.3.1, but it didn't help. Did a hard reset, factory default reset, soft reset, nothing worked.
Next I tried swapping the two, putting the old Express back on the DSL line and the new one as the bridge to extend the network (using WPA2). But the 802.11n complains that it can't access the network and flashes amber.
Again, tried upgrading to 7.3.2, downgrading to 7.3.1 and 7.3.0, hard reset, soft reset. Nothing works.
Any ideas?
Cheers,
Fairfax71

I don't see any option in the Airport Admin Utility for the old Express for creating a WDS network, only to participate in one...?
That is the option you want to choose.
You could use the newer AirPort Utility to configure the older AX.
Sorry, forgot to ask something else: The 802.11n Express is able to join the WLAN created by the 802.11b/g Express as a client, but not extend it, is that what you're saying?
No. If you join the network the AX is simply acting as another wireless client and is not extending the network. The "extend" option is not available since the older AX is not 802.11n capable. You must use WDS.
Use AirPort Utiity and follow these steps for both AX's. To set up the main AX:
Click the AirPort status menu in the menu bar and choose the wireless network created by the base station you want to set up as the main base station.
Open AirPort Utility (located in the Utilities folder in the Applications folder on a Mac, or in Start > All Programs > AirPort on a Windows computer). Select the main base station, and choose Manual Setup from the Base Station menu, or double-click the base station to open the configuration in a separate window. Enter the base station password if necessary. If the base station is using the default password of public, you will not be prompted for a password.
Click the Wireless button, and then choose “Participate in a WDS network” from the Wireless Mode pop-up menu.
Click WDS and then choose “WDS main” from the WDS Mode pop-up menu.
Select the “Allow wireless clients” checkbox if you want client computers to connect to this base station.
Click the Add button and enter the MAC address of the base stations you want to connect to this base station. If there is a base station listed that you’d like to remove from the list, select the base station and click the Delete (–) button.
Click Update to send the new settings to the base stations in the WDS. By default, the “Allow wireless clients” checkbox is selected. If you deselect the checkbox, and later want to change the settings on the base station, you must connect to the base station’s LAN port with an Ethernet cable. You will not be able to connect to the base station wirelessly.
To set up the second AX to connect to the main AX:
Open AirPort Utility. Select the AX, and choose Manual Setup from the Base Station menu. Enter the base station password, if necessary. If the base station is using the default password of public, you will not be prompted for a password.
Enter the same network password as the main base station, if necessary.
Click the AirPort button, and then click Wireless. Choose “Participate in a WDS network” from the Wireless Mode pop-up menu, and choose the same channel as the main base station from the Channel pop-up menu.
Click WDS and choose “WDS remote” from the pop-up menu.
Enter the MAC address of the main base station in the WDS Main field. The MAC address is also referred to as the AirPort ID and is printed on the label on the bottom of the base station.
Click Update to transfer the settings to the base station.

Extending a network with Airport Express 802.11n-2.4 or 5.0GHz?

I've just ordered an AirPort Express N to extend the network of my AirPort Extreme (Gigabit) and run AirTunes. It'll be connected to the router by Ethernet.
My question is this: can I run the Express at 2.4GHz (802.11b/g/n) while I run the Extreme at 5.0GHz (802.11n only), even though they're on the same network? I've got a couple of 802.11g machines (my old iBook and my iPhone, for two), so I need to keep backward-compatibility, but I'd love for the 802.11n machines (my iMac, and my wife's Mac Book) to connect at the higher speed. Can you extend a network on different frequencies?

No, not while they are in a WDS. If you want to operate wireless networks in both radio bands, you would need to configure the base stations in a "dual band" network.
Setting up a "dual band" network is described in the Designing AirPort Networks document, starting on page 48.

Advised to get an "extender" to be able to stream netflix, etc. through new digital tv. Apple store told me to buy Airport Express and set up WDS. Upon reading about WDS it stated cannot set up WDS with Airport Express 802.11n,

I was advised I needed an "extender" to stream Netflix, etc. through my newly purchased digital TV. Apple store advised me to buy Airport Express and choose WDS setting. When reading instructions on how to set up WDS it states cannot set up WDS with an 802.11n airport express, which is what they told me to purchase. How do I set up this Airport Express to extend my internet signal from my modem & airport to be able to stream internet capability to my TV?

Port Forwarding with Airport Express 802.11n Utility version 6.1

Hi all,
Quick question, hoping it can be solved with a quick answer
Not sure what I'm doing wrong: I'd like to set up port forwarding for Skype and Transmission, however in the airport utility even when I assign the public/private ports to the ones specified in the respective programs (with the IP address for the machine I am using), if I go into Transmission or onto a port checker website the connections are shown as closed for the ports I have selected (on the public side).
I've made a DHCP reservation for this machine to tie it to a given IP address, and I've enabled NAT port forwarding protocol in the Network options (no default host so far).
Also, in case it makes a big difference, right now I'm connecting to the internet via a Cisco DCP3825 cable modem running in bridge mode, with the AEBS in DHCP and NAT router modes.
Any tips?
Thanks!

Sadly I never got it to work. I called up Apple and they claimed that all the ports are open for the Airport Express, but if I run port scanner in Network Utilities none of the ports I specify show up as open unless I select one of the "Default" port categories like "Windows File Sharing". I told this to the person I spoke to on the phone, and they replied several times in a row that they are not allowed to help set up port forwarding, that they can only provide info on how to open the ports, and that even if the ports are subsequently not opened or forwarded they can't provide any assistance. It wasn't a very good conversation. Unfortunately, based on some of the other disucssions I've looked at in this forum, it doesn't seem possible to do conventional custom port forwarding using this version of the Airport Utility. Hopefully someone will correct me though. Sorry I can't be more help.

PC causing interference with Airport Express 802.11n

Hi there,
My airport extreme base station is operating in WDS mode, with an Airport Express as a remote wds.
When i power on a Dell laptop in the house where the AEBS is, the wireless connectivity for any Macs or Pc's connected to the AEBS grinds to a halt. After a few seconds, the AEBS provides zero connectivity. When I turn the Dell's power off, the AEBS signal builds to where it was prior to the Dell being turned on, which is very strong.
The wireless antenna for the dell is not even powered on, and it is not connected to the AEBS via wire either.
Has anyone experienced this kind of interference with the AEBS? I would like to use this Dell on the AEBS network via wireless. Unfortunately, tossing the Dell out the window is not an option for me. Thanks!

Seems the Dell's docking station was interfering with the ABS. Strange.

Connecting with AirPort Extreme 802.11n

Could someone please provide instructions in plain english, no computer jargon or techie stuff, exactly how to connect to the internet with my Airport Extreme? Apple support is no help, I cannot understand the terminology they use and my brand new MacBook doesn't seem to have all the same features that they're telling me are on it, so I don't know what to click.
What a mistake buying this overly complex Apple product! This is my third MacBook, I hope somehow I can get this thing running!

It's a good thing that you didn't try this with a Windows based computer!
I suggest that you call the "Geek squad" or something similar close to your geographical location. There is absolutely no way to explain this to you without using "computer jargon or techie stuff". To configure a computer and a network you must use those terms.

Cannot Connect Airport Express 802.11n to WEP 64 Bit Wireless Network

I am currently use a Netgear MR814 who's only built in security is WEP 64bit.
I am attempting to connect my Airport Express 802.11n to it and I see the WEP 40 bit option and use that and it puts in my password for the wireless as 0xPASSWORD.
However it is unable to connect to the network. I scoured these forums and attempted the "$" escape character and the "" option by none of these work.
Is there a way for me to configure my AE to be able to connect to my (older) wiresless router?

I found information indicating that this airport express must be set up by airport utility 5.6.1, but that version is not supported by Lion.
AirPort Utility 5.6.1 is not supported by Lion....it was designed for Snow Leopard.
You need the correct version of AirPort Utility 5.6 for Mac OS X Lion
Give the correct version a try and then please report on your results.
