Airport Extreme Dropping Connections

Hi, I have an AEBS, connected to a comcast "Teralyn" cable modem. I have a PowerMac Quad Core, connected to the AEBS by an ethernet cord, and we have an IBM ThinkPad and a PB15 G4 that we connect to the AEBS wirelessly.
Up until a day or so ago, everything worked great. But starting yesterday the connection to the AEBS and to the Internet from the Cable Modem drop intermittently. Seemingly no rhyme or predictability.
When I disconnect the AEBS from the cable modem, there is stability in the network. When I reset the AEBS and restart the cable modem, the problem persists. Random disconnects.
Im running the following setup:
- V5.7 on the AEBS
- OSX 10.4.4
- Airport Firmware V404.2 (3.90.34.0.p16)
Any help is greatly appreciated. Any ideas... I've tried a bunch and am ready to throw my AEBS out the window.
Thanks.

Hello, I'm having kind of the same problem.
I have an airport extreme set up to connect to an adsl modem. There are 1 IMac, 3 PC running XP SP1/2. Everything works fine (Good signal strength, excellent speed, etc.) except for one pc (xp sp1 all updates with USR5416).
It randomly disconnects from the base station without apparent reason. Often, it reconnects within the 5 following secondes.
The annoying thing is when the connection application in my task bar starts flashing : connected/disconnected/connected/disconnected... it can last from 10 seconds to several minutes while it's impossible to do anything networked.
Any idea?
The airport extreme is updated to the latest firmware, so is my USR wireless card, windows xp, etc...

Airport Extreme drops connection for a few seconds at a time

My airport extreme seems to drop its connection for about 5 seconds at a time and then is back up. It does it every 10-15 minutes or so. I am not really sure why it is doing this because it has just started happening recently and worked fine for months and months. I need help because I dont know much about networking.

When you inserted your AirPort Extreme (It was an AirPort Extreme card, right?) card in your G5, did you attach the antenna cable AND the external "T" antenna?

Linksys WRT54GL and Airport Extreme dropping connections

In looking through these forums, I realize that people have had problems with their Linksys WRT54G routers and their Airport cards. There seem to be a lot of suggested fixes, but no definitive answer as to what's wrong. I don't know either, and after changing channels, changing Linksys firmware, changing encryption, creating background pings, and all of the recommended solutions, the problem persists. I wanted to document it here in the hopes that someone can figure out what's wrong. Here's a tail of /var/log/system.log during a period when the Mac was having trouble connecting to the Linksys. I don't believe that this is due to Wifi interference or the Linksys, since other machines in the house (a Mac running 10.4.8, but using a Cisco card), for example, don't have these same problems at this time.
Basically, this kind of behavior repeats for a half-hour or so, then settles down for "a while," where a while could be an hour or could be 6 hours, and then it repeats. I have no idea what the problem is, and I suspect it's a problem with the Airport Extreme, rather than with the Linksys. Ideas?

I thought I understood your Airport network would disconnect, but I don't understand what you mean by "drops ethernet". Clearly, if your wired connection stops working, so will your Airport network. Explain?
What I am saying is that I have wireless connections to the Ae and I have wired connections to it as well. Both are getting dhcp from the Ae. Both are getting dropped. In the log I am getting these entries, about once per hour...

The 10.0.97.190 is the recently-added OS X Server. Not sure what the port is. But it seems to be doing something untoward.

Airport Extreme dropping connection with a Cisco 5 port Giga switch

I've connected a Cisco 5 port Giga switch SG100D-05 to one of the LAN ports of the Airport Extreme and for some reason the connection is being dropped or it fails to connect. Any idea of why this is happening and how can it be fixed?

If you have not already done so, you might want to do some basic troubleshooting to try to isolate the cause of the issue.
To do that, temporarily disconnect the switch and power it off. Connect a computer with an Ethernet port on it to the LAN port on AirPort Extreme and turn off the wireless on the computer.
Test to see you can get a good Internet connection this way.
If you can, then you know that the LAN port on the AirPort Extreme is functioning correctly and your troubleshooting efforts will need to focus on testing each port on the Cisco switch.
If you cannot get a good connection with the computer connected directly to the AirPort Extreme, try another Ethernet cable that you know is working to eliminate the possibility of a bad Ethernet cable, which is the culprit more often than you might think.
Please post back on the results of your testing.

AirPort Extreme dropping connection to printer

Help. AirPort Extreme disassociates/disconects from AirPrint printer(HP 7525) after ten minutes. Only way to reconnect printer is to constantly reboot AE. After ten minutes or so it disassociates/disconnects again.

It's an RCA Digital Broadband router. All activity on it seems to be just fine, and I like I said, my internet connection never goes down...it just stops sending things to the printer.

Airport Extreme - Dropping connection

I have an issue with my wireless network continually dropping out and then re-connecting.
I use an Aiport Extreme 802.11g and have an airport express connected to the same wireless network. I use WEP 128 bit security (occasionally a PC makes its way into the house and wants to connect) and I use MAC Address access control. The signal strength is fine.
The log shows repeated entries of the following message (the MAC address belongs to my computer).
Jun 10 21:46:15 Severity:3 Administrative access denied to fe80::21b:63ff:feca:b682%mirror0/53771.
Anyone have any suggestions as to why this is occurring ? Thanks....

Welcome to the Forums!
Hmm, strange Logb entry... pondering/searching.
There've been many with this problem, and dozens of assorted cures, none that work for all, but to start...
Change the Channel.
Shut off IPv6.
Shut off any 802.11n possibility.
Switch to WPA/WPA2, (btw, WEP 128 takes about 3 seconds to break now, and somebody spoofing your MAC addy would boot you off toot sweet).

Hi..I have an AirPort Extreme base connected to my DSL Modem and has been working fine. But I recently bought another DSL modem along with the latest Airport Express. With this one however I can't get it to connect to the Internet. Any suggestions?

Hi..I have an AirPort Extreme base connected to my DSL Modem and has been working fine. But I recently bought another DSL modem along with the latest Airport Express. With this one however I can't get it to connect to the Internet. The light on the Express is flashing green though. Does it mean I have to re-set the settings on Airport Utility? I.e. the old settings haven't been cleared yet. Any suggestions?

Let's see if I can get this straight.
You have an Airport Extreme base station that is set to "Create a wireless network" and you have the box checked for "allow this network to be extended"....
Then you have an Airport Express that is set to "Extend a wireless network" which you selected the name of your network in the box...
Correct?

No, not unless it is simply a network connection.
How is your IPTV being provided.. if it is using a separate vlan or separate vpi/vci in the adsl connection. Who is your ISP?
Is the TP-Link ADSL?
Is the IPTV using a separate voice channel on adsl?
Or a different vlan.
Sorry but it is something where a definite answer is not possible unless you provide all the details.
The setups are unique to each ISP around the world..
Here is one for our local ISP.

He has a section on getting this working with apple router over wireless.. look
http://www.avenard.org/iptv/IPTV_and_Wireless.html
Google around and see if other people have had success.. the whole setup is tricky.. and it is hard if nobody has used it who actually understands networking.

Derek-
Since I could not find an answer on the support site. I contacted Apple Support. Once I explained the symptoms the tech seemed to know exactly how to address my issue. I will explain what happened in hopes that it will assist you. It seems that the issue has to do with the type of wireless network security set up in the Airport Extreme that conflicted with the Vista notebook's wireless adapter.
The tech had me launch Airport Utility, log into the Airport and Click on the Wireless. First he had me change the Radio Channel Selection from Automatic to Manual and changed the 2.4 GHz channel to 9 (from default 11) and the 5 Ghz channel to 157. The wireless security was set to WPA/WPA2 and he had me change it to WEP (Transitional Security Network) and I entered a 13 character key.
This resolved the internet connection issue with the Vista laptop immediately, but now I cannot print to my wireless Lexmark printer. I have a support email to Lexmark. It seems that the Lexmark driver/software only lists WPA in the install dialog and does not include WEP. My guess is that this is the source of the problem.
I hope this helps.

Should I disable the wireless capabilities of my Bigpond modem/router when Airport Extreme is connected?

Should I disable the wireless capabilities of my Bigpond modem/router when Airport Extreme is connected? I'm told that it's better to only use the WiFi capabilities of the Extreme and leave the Bigpond to feed to the extreme.

No, bridge mode would not be the correct setting for this.
Instead, look for a "wireless settings" tab or page that will provide the option to turn off or disable the wireless radio of the BigPond router.
If you are still having difficulty, it would be a good idea to post your question on a BigPond support forum or contact your Internet Service Provider.

Devices not connecting through Airport extreme wired connection

Hi
I just got an Airport extreme to use as an extention of my existing network, and to plug some devices in so that they can connect to the internet for updates (Sony Blu-ray player, dish network receiver, slingbox)...
my wireless is from a linksys/cisco wireless router (4-port) wrt310n, that is connected to my cable modem. The airport is set and has the green light showing. The blu-ray player and dishnetwork receiver are plugged into two of the ports. The blu-ray player says it can't connect to the internet. The dish network receiver says it is connected, giving ip address/submask, etc.
If I take my macbook pro and turn off wireless and plug into the airport it will not connect to the internet.
What have I not done to allow wired connection to the airport extreme to connect to the net?
thanks
David

Thanks for the clarification of your setup.
Unfortunately, the bottom line here is that this is not going to work.
The ethernet ports on the Extreme will only be active if you configure the AirPort Extreme to "extend a wireless network". But, it can only "extend" a wireless network from another Apple router. It's not compatible for this purpose with your Cisco router or any other manufacturer's router.
If you are unable to connect the AirPort Extreme to your router using an ethernet cable, you might want to take a look at a pair of ethernet powerline adapters to accomplish the same task by using the wiring in your home to transmit the ethernet signal.
I should clarify that if you connect the Cisco and AirPort Extreme using ethernet, you would not use the "extend" setting on the AirPort Extreme. This is only used if the device is connecting to another Apple router.

Will a WD hard drive work with AirPort Extreme to connect with an iPad Air

Will a WD hard drive work with Airport Extreme to connect by a iPad Air

If you already have an AE and a WD drive .. the best idea is plug it in and see on a mac in airport utility is the drive recognised.
If not you have problems.. if it is formatted correctly (Not NTFS mainly) then it can be a drive that is not compatible.
assuming it works get your ipad and pay for filebrowser or at least download a test copy and see how it goes.
Always the best way to find out.. try it.
