AE Issues & Wireless Clients listing in AEBS goes blank?

Strange behaviour:
I have a network with 1 AEBS and 2 AE acting in a WDS.
With both AEs turned off, Airport Utility's Wireless Client listing (under Advanced/Logs & Statistics/Wireless Clients) shows a list of all the clients that the AEBS is hosting on the network. Yay!
Issue #1:
When I turn on one of my AEs, that list goes blank. Not a biggie, but I'm curious as to what is happenening there.
Issue #2:
I am not able to configure the AE! Airport utility lists it, but returns the message "An error occurred while reading the configuration"
(I recently updated the AE firmware to 6.3...)
What to do? I tried linking my mini to the AE with ethernet, but it didn't show up in the Airport Utility listing of base stations.
Any searching tips or advice welcome!

Hi joedornan,
I have the same problem with wireless client list. since some software update came out (i don't remember which it was) my AirPort Utility (ver. 7.2.1) is not showing the Client list, and when i want to click on "Wireless Clients" i am transferred strait to "Log's List" without any option to check Wireless Clients.
I have no idea what that such thing are happening.

E1200 Wireless Client List will not display and causes web UI to temporarily stop responding

I picked up an E1200 and set it up successfully. I am using wireless MAC filtering, and decided to pull up the list of connected wireless clients (Wireless >> Wireless MAC Filter >> push "Wireless Client List" button).
When I do so, it immediately throws this back:
Immediately after this the Web UI of the E1200 becomes inaccessible. It still routes traffic, and the router remains pingable, but it will not allow access to the Web UI for several minutes. The error that appears upon attempt to access the Web UI during this time window is similar to the above, but reads "Error 102 (net::ERR_CONNECTION_REFUSED): The server refused the connection."
I have tried this in Google Chrome, Firefox 4, and MSIE on two separate computers. Each browser displays the error a bit differently (MSIE, for example, just says it can't display the page and gives no further detail) but the net results are always the same. I have tried resetting the device to factory defaults in addition to re-downloading the firmware from the Cisco/Linksys website and installing it. No improvement.
I have also noted that the Log (Administration >> Log; and yes, I have it enabled) doesn't appear to be picking up anything at all. In fact, the Security log, which supposedly (according to the Help) "displays the login information for the Router’s browser-based utility," is also blank.
Is this a bug, or should I head back to the retailer and swap this device?

Ok - I nailed this down, I think, and it looks like a firmware bug.
Short version is that a factory reset cleared the issue, but during stepwise reconfiguration the problem came back. Through a bunch of iteration I figured out that if I have the E1200's DHCP server disabled *and* have wireless clients connected to it, the problem I described appears.
Turn the DHCP server back on and the problem goes away. Turn it off and the problem comes back. Turn it back on and it goes away. You get the idea.
If I had to pose a theory here, it's that the initial display of the Wireless Client List, which uses "IP Address" as the default sort, somehow implodes if the E1200 isn't actually assigning those IP addresses to the clients.
When this happens it appears to crash the Web UI wholesale. Just for grins, while the Web UI was unresponsive, I pinged the router it as before - still pingable - then ran nmap against it - no open ports found on the router. When the Web UI is functional, though, nmap detects port 80 quite easily. I have not timed how long it takes for the Web UI to come back up, but it is longer than 5 minutes, and I presume some sort of watchdog process has to detect that it has gone kaput and start it up again.
Final test was to restore my saved configuration from before the factory reset (note that the saved config was done under the same firmware version, and in this config, the DHCP server is disabled). Boom, problem. Wait for the Web UI to come back, turn on the DHCP server. Problem goes away. Turn the DHCP server off. Boom, problem comes back.
So, there you go.
Would be interesting if someone could verify this via a test against another E1200. It may be worth noting that in my baseline test I was also using Manual wireless setup (vs. Wi-Fi Protected Setup), and WPA2. Didn't make any other setting changes from the factory defaults. I did not actually have to turn the Wireless MAC Filter on to do the test. All one needs to do is click Enable on the Wireless MAC Filter tab, and then do *not* click Save Settings - just clicking Enable will light up the Wireless Client List button, which you can then push to get the list. That is how I handled testing to ensure that neither specific entries, nor the Prevent/Permit setting, nor having the filter enabled in saved configuration were involved in the problem.
Separately, no explanation for the lack of entries in the security log, but that pretty much looks like a firmware bug to me as well.

Wireless Client List keeps getting strange addresses

I am having some issues with the wireless client list in my Linksys E3000 wireless router. I want to use the wireless client list and enter the MAC addresses of the devices that I want to have access. Any where from 5 minutes to a couple days, more MAC's have been added to the list, from devices that don't off hand belong there (not mine). Sometimes, some of the devices that I have put there, will be removed and replaced with the others. Those that are replaced then do not have access. There are about 18 common MAC's that show up.
As an experiment, after many times of replacing these stray MAC's, I tried putting all of the stray MAC's in and restricting them from access. That was good for about 24 hours and the list was misteriously deleted from the restricted list. There is no common thread between time or devices connected.
The following is a list of devices as they appear. Most will reappear after being deleted from the list:
0A:60:76 Unknown
00:FF:30 Unknown
00:25:F0 Suga Electronics Limited
00:1F:16 Wistron Corporation
70:1A:04 Liteon Tech Corp.

00:26:9E Quanta Computer Inc
08:00:27 cadmus computer systems
00:10:75 Maxtor Corp. (was: creative design solutions,inc.)
I have assigned IP's to the devices that I want connected.
I have reset to factory settings.
I have the current firmware. I even reinstalled the current firmware.
I have scanned for viruses and malware.
I am using WPA2 security.
The only hardwired computer that I am on now is running Windows 7. All other computers are running W7. All computers are up to date. All antivirus and malware soft is up to date. All other devices, (cameras, drives, printers, etc.) have firmware up to date.
Any suggestions?

Here is the issue:
If I use Permit, MAC's are added to the list which eventually fills up and starts knocking off the one's that I want there.
If I use Prevent, the MAC's that have appeared in the Permit list will start disappearing from the Prevent list.
I have WPA2 Personal encryption on. Remote access turned off.
If I have the Prevent list on with Remote access off, how are these stray MAC's being removed.
If I have the Permit list on with Remote access off, how are these MAC's being added and removing the correct one's.

WRT120N: Wireless Client List - Refresh button useless

WRT120N:
Wireless --> Wireless MAC Filter --> Enabled --> Wireless client list...
Opening Wireless Client List on WRT120N shows the list of wireless clients connected.
Add button is working.
Close button is working
But Refresh button is useless. Even if clients on the lists are already not connected to the router, pressing the Refresh button does nothing. It may add new clients connected but can't determine whether the client disconnects or not. The only way to determine if the client is still connected or not is to Reboot the router (Administration --> Start Reboot).
Refresh doesn't update/remove disconnected clients from the list.
I'm hoping that on future firmware updates for WRT120N, this can be fixed.

Did you try to upgrade/re-flash the firmware on your router?
Connect the computer to the router with the Ethernet cable. Download the latest firmware from Linksys website and save it on your computer. Upgrade/re-flash the firmware on your router. After upgrading the firmware on your router, reset the router and reconfigure it.

WRT160Nv3 - Clicking "wireless client list" button kills WRT160Nv3 web interface.

Clicking the "Wireless Client List" button on the "Wireless MAC Filter" page causes a new Internet Explorer instance pop-up containing the the error: "Internet Exploer cannot display the webpage".
After the error appears, I can no longer access the WRT160Nv3 via it's web page interface. I just keep getting the above error message. But I can bring up a command prompt and sucessfully PING the WRT160Nv3. I just can't get back to the WRT160Nv3 router's web interface.
If I wait about 24 hours (or so) the WRT160Nv3 web interface is accessable again.
Why is this happening, how do I correct it and how do I get a list of all the wireless devices connected to my WRT16Nv3 router?
Thank you.

Okay, I'll assume the solution of resetting (and then recofiguring) the WRT160Nv3 router gets the router's web interface working again.
But how do I see which of my client devices are actually connected to the WRT160Nv3?
Clicking the "wireless client list" button appears to causes a problem for the router's web interface and then requires resetting and reconfiguring the router.
It seems like I still don't have a solution that shows me which devices are connected to the router. And I have to reset and reconfigure the router if I attempt to invistigate which devices are connected to the router.
Any additional insight would be appreciated.
Thank you;

WRT600N Doesn't show any entries in the Wireless Client List

Hi, my WRT600N is on firmware 1.01.35 build 3. When I check the wireless client list from the Wireless MAC Filter page, it is empty, even though I know I have 3 clients connected. They are all using 802.11g, as I don't have any N devices yet. When I go to the Status page and check the DHCP Client Table, both of my wired clients are there, but only 1 wireless client appears. The DHCP Client Log file is useless, as it only appears to log the ip address it receives from my isp. There are no entries of the ip addresses it has given out. Is my WRT600N defective, or is there firmware in the works to correct this?

Another thing I've notice, is that the DHCP client table is showing the 2.4 wireless devices as LAN interfaces. Shouldn't it show the frequency, like it does my one 5GHz device? Things have changed, because the Wii is now showing in both the Wireless Client List, as well as the DHCP Client table. It shows as a LAN interface though, which is wrong, it should be 2.4GHz. My one pc that is a 5GHz N device, is also showing in both the Wireless Client List, & the DHCP Client table. Neither the wireless 2.4 gaming adapter, or the HR20 connected to it show up in either list. Neither does a laptop which is 2.4GHz. This is really a concern, because I've caught 2 neighbors stealing my bandwidth in the past, and I can't stop them if I can't see them.

Getting Wireless client list in WRT54G?

On one of the other sites Isaw a post showing a URL you could use to get a WRT54G to lsit the currently connected wireless clients. unfortunately this URL did not work on my v5. The DHCP client list is useless because I host my DHCP server elsewhere and don't use the internal server.
Does anyone know how to tickle a WRT54Gv5 into giving up the wireless client list?
Thanks In Advance,
Mark

The wireless client list is available in the WRT54G v5+. The URL is http://192.168.1.1/WClient.htm
The button to display the table is hidden until Wireless MAC Filter is ENABLED on the /Wireless/Wireless MAC Filter page.
http://192.168.1.1/WFilter.htm

My bookmark tab will briefly show my bookmark list but then goes blank. Retry and get same issue.

i see the outline of the bookmark dropdown but it is blank inside. when the dropdown worked yesterday it left the listing of bookmarks at the bottom of the browser page and i could not get rid of them unless I closed the browser

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Appearance/Themes).

This can also be a problem with the file places.sqlite that stores the bookmarks and the history.

Client List for DHCP is blank

I'm running DHCP off of a XServe and it is
dishing out the addresses and is working, but the list of
Clients is blank and Number is Client is 0.
The client pc's and mac's show that they are
getting their IP addresses from the correct dhcp server
and the dhcp logs show which addresses went to which
clients but nothing in the Clients tab on Server Admin.
Any ideas?
Thanks,
Tadashi

I am having the same problem. We're running 10.4.6 on an XServe G5 as an opendirectory replica. Did you find a work around?

Airport Extreme and Dlink dwl-2000AP+ as wireless client

Hi,
i'm trying to let an old iMac G3 without any airport card, join an existing lan using an Airport Extreme as router, connecting an old D-Link access point configured as wireless client and connected via ethernet to the iMac G3. All my setup works fine if the wireless connection is open without encryption, but it won't work using any protection like WPA or WEP.
When the airport express wireless connection is protected via WPA, the dlink won't be present in wireless clients list panel. When i use WEP (with a password of 13 characters) i can see in the wireless clients list both the MAC address of the iMac's ethernet and of the dwl-2000AP+ etherenet. But the connection won't work.
I'm sure i'm not configuring right the DWL-2000AP+ wireless protection:
i can't understand if i can change the airport express WEP encryption to a 64 bits or to a 128 bit, if the WEP method used is with a shared key or not.
The only info i get from it to let the clients connect are the WEP ASCII plain-text 13 characters password and its conversion in HEX base.
I'm assuming, since the password is a 13 character, that in WEP encryption the Airport Extreme uses a 128 bits key, but, again, how i can understand if it is used in shared way or in open way?
And why the dlink AP that is WPA capable cannot connect as wireless client to the airport express when is using WPA/WPA2 Personal encryption?
I upgraded the DWL-2000AP+ to its latest firmware that (they sayd)fixes any issue with the wireless client mode on WPA or WEP protected connections.
Thanks in advance for any help given.
P.S.: sorry for my "broken" english
Message was edited by: Rayced

Resolved by myself. It works only setting the Dlink dwl-2000AP+ wireless client connection (wireless pane in the admin control of it) as open with WEP 128bits and using as key an ascii password of 13 charcaters. The Airport Extreme's wireless encryption should be set as WEP, using the same password of 13 charcaters. I still can't uderstand why the WPA/WPA2 encryption wouldn't work since the Dlink dwl-2000AP is WPA capable.
Maybe it could be so because the Airport Extreme is WPA2 and at the first negotiation between it and the dwl-2000AP+, the Airport Extreme won't downgrade to WPA encryption? Does anybody else tried to connect a WPA wireless client to the Airport Extreme setup as WPA2/WPA Personal?
@wallstreet 04: try to setup your Airport Extreme's wireless encryption to WEP and use a 13 chars password, then do the same on the Dlink wireless client you are trying to connect to the base, i don't know how is its control panel but the wireless should be setup as open with WEP 128, as key use that 13 chars password you put in the Extreme's as WEP password. If in the Dlink WEP 128 bits key field you have to put an HEX value instead of the ASCII, you can get that from the Airport Utility from the menu BASE AIRPOT select PASSWORD NETWORK... (the one before the last choice that should be ADD WIRELESS CLIENT).
I hope it will help.

"Wirless Client List" button on WRT160NV3

Has anyone had any joy getting the Wireless -> Wireless Mac Filter -> Wireless Client List button to work?
I've tried several browsers, and several versions of the firmware (v3.0.02 and v3.0.03) but no joy.
In each case my browser pops open a new empty window and then it appears the webserver running on the WRT160N crashes. It no longer accepts any more connections on port 80, although continues to operate fine as a wifi router. I need to powercycle it to get the management web interface working again.
And yes, I did the full "reset-to-factory defaults + reload my configuration" dance after the firmware upgrade.

Whenever you upgrade the firmware on your Router, you don't need to load the configuration on your Router, you need to configure all the settings on your Router from scratch.

All devices listed as wireless clients not showing up.

I have an airport extreme (newest version) I have my apple tv, computer and ipad showing up listed as wireless clients, however my iphone does not show up. It is connected to my network. I have tested with another iphone (same version 4S and same iOS) it shows up but not Mine.
Do u know why it is not showing up?

remove power cord from the PSU and >>Clear CMOS Guide<<
if the wifi card is removable, try to reseat it
also install latest killer drivers from:

[try older version as well if needs]

AEBS(n) Add Wireless Client Help?

Using the Airport Utility for my AEBS(n), it has a menu item in the Base Station Menu (on the menu bar) labeled "Add Wireless Clients..." It apparently allows you to have a temporary pin number to allow short access to the network without the WPA key.
The textbox only allows 8 numbers, and won't allow letters/characters. I've tried to get this to work, but after entering an arbitrary Pin in the textbox, the Continue button at the bottom of the screen never becomes enabled.
I have WPA/WPA2 enabled. Is there something in my setup that is preventing this from working? The help files are no help...

That is only an option if you are using MAC address filtering. Since you are not, you don't have to worry about that.
Is your AirPort Express (AX) set to 802.11n operation only? If so, is this Windows laptop capable of 802.11n? If not you will need to configure the AX to a 802.11b/g compatible mode.
What type of wireless encryption are you using? Is this Windows laptop compatible with that?
If you are outside the US, try configuring the AX to use a channel between 1 and 11.

Routing issues roaming wireless clients?

Hello,
I have a site with wireless roaming printers that have static ip addresses and can roam throughout the building. Several times an hour the print server (in another building / subnet) cannot ping the printer therefore cannot send its print job. Whats odd is that they can ping the printer from the associated AP and can ping from a laptop associated to the same AP. Communication can go down from the server to the printer(s) for several minutes and then just reconnect. I see syn packets leaving the printer but not getting any syn/ack back. I also cannot ping the printer from a different subnet / my vpn connection. Is there any issues with roaming wireless clients and routing protocols / spanning tree that could cause a problem? I can only imagine with mac addresses moving from one AP to another that something could break. The AP's are 1210's with b radios running 12.3(2)JA2.
Thanks in advance.

Hi
Thanks for ur reply the problem has been taken care of by configuring the smartports as others and getting the arp inspection disabled

DHCP client list

Hello,
I recently set up my Mac Pro to act as a gateway and the setup has a AEBS acting as a bridge to all the other clients (dont want to buy a extra switch). I just wanted to check to see if the AEBS is the reason why my DHCP client list on the server only shows the AEBS and not other clients, wireless or wired. Is there a way to fix this issue without going to a switch? All connections on the AEBS is on the LAN side and the WAN side not plugged into anything.
Thanks!

Greg,
Not that I know of.
I made a cheat sheet with a list of my computers and wifi gear using the last 2 digits only.
1. My Mac = 09
2. Wifes Mac = D3
3. Printer = 37
etc., etc.....
