Access Points do not show in CDP neighbor

Hi All,
Last night I was performing mainteance on access points throughout the network. I was converting them from Local to H-REAP to allow for vlan support. The maintenance went well however afterwards I've noticed access points are not showing up in CDP neighbor and with a "show power inline" the access points shows as a IEEE PD. This is causing some weird issues where a client can connect but then will lose it's DHCP address. The problem happened on 9 of the 12 floors that I did this on and there is no configuration differences and bouncing the access points did not resolve the issue. The access points do show a blue light.
Has anyone ever experienced this before? If so what did you do to fix it?
I have a mix of 1131 and 1142N access points on a 4402 WLC running version 6.0.188.0.
Thank you,
Chris Pratt

I see all the time.
"sh cdp neigh" shows nothing and "sh power inline" shows the port connected to the WAP as "IEEE". This is mostly caused by faulty cabling. If you have the right Cisco switch, you can test the cable using the in-built TDR feature.
Here's how you do it:
1. Command: test cable tdr interface
2. Wait for about 5 to 7 seconds;
3. Command: sh cable tdr interface
4. Please post the complete output.

Access Points report half duplex in CDP Neighbors

Hi
We are currently converting our AP's to light AP's - using a 5508 controller. I just noticed that when I check an AP, under Access Point Details, CDP Neighbors, it correctly reports the switch it's connected to, with the right port. But under "Duplex" it says Half Duplex?
It seems to do this for all AP's. I have checked both an 1121, 1131 and 1141. When I check the connected port on the switch it says Full Duplex.
Is this a display issue or something I should examine further?
Regards,
Kaj

Leo is correct. There is a bug that causes this. It will also eventually cause the controller to lock up. On a 2106 this happens much more often due to the lower amount of memory and processor power. TAC suggests that you hard code the switch to 100 meg full but I have seen that his has no real effect.

Access point are not coming up after upgrade image of WLC

Hi,
I have AIR-WLC4402-50-K9 WLC i that current IOS is 7.0.98.218 and i upgraded with 7.0.116.0 IOS but after upgrading and reboot the WLC from 15 access point 3 access point are not coming up and 12 are coing up and working fine (4 1142 and 11 1131 series access point) 3 which are not coimg is 1131 series access point. when i login with console to 3 access point its rebooting 2 times and coming on ap: prompt.
In between that i reloaded the WLC one more time because from 15 acess point only 4 aceess point are came up and i also cleck the show boot on wlc its output is
7.0.116.0 (default)
7.0.98.218 (active)
so i reload the wlc and checked out of 15 acess point now 12 acess point are up and still 3 are not. And i also checked the output of show boot command its
7.0.116.0 (default)(active)
7.0.98.218
So i things its because of when 2nd time i reload the wlc the remaining 3 access point are getting image from wlc but because of reload its connection should be loss and error loading flash error are coming on acess point.
After that i recover the IOS for access point and convert into autonomus and from autonomus convert into Leightweight Access point. I also attached the procedure for recover the ios of access poing
But my question is why this 3 access point are not coming up is this happen's after upgrading wlc can any one please send me Step by Step WLC S/W Upgrade' process and if this this happens some time please send me any doccument related to this.

Sunil,
When you rebooted the controller did you do it from the Web GUI, the CLI, or did you physically reboot the controller? I believe and maybe incorrect but if your getting the ap: < prompt > that means that there is no firmware on the unit. If you have restored these to functioning autonomous unit and then re-converted them to Lightweight and it's still happening then we need to look at a debug output of what is happening when those AP's attempt to join the controller.
The capture you attached shows that it appears to join the controller and get a config, but are you saying that when it reboots again it stops working?? the other thing I would reccomend is clear out the flash memory since your capture shows the possibility that there are several copies stored there.
Hope this helps.

I am trying to softproof an image using a CMYK .icc file. I sent an image from LR 5 to PS CC 2014, opened the Camera Raw FIlter, but the hyperlink to access workflow is not showing up in the CR dialogue box... Any ideas why this might be?

WRT160N Useable as a switch/access point but not as an internet gateway?

Greetings,
Can anyone tell me if it is possible to use a
WRT160N wireless N router as just a switch and wireless LAN access point and NOT as an internet Gateway? I have a LAN that is not connected to the internet that uses a Linksys switch and I need to get a wireless access point setup so that I can attach a computer wirelessly to this LAN. Occassionally I connect the swich to another router that does have internet access, but in general the LAN is not connected to the internet router.
Thanks!

You can use WRT160N as a switch...Connect the LAN to the Ethernet port of the router and change the ip address of the linksys router in the range of the LAN ip.

Cisco Access Point is not Broadcasting

Hello ,
one of my Access Point is showing up in WLC but not broadcasting .
any Idea Please advice.

Hi Islam,
In WLC GUI ( go to Wireless tab) & select the AP
1. Check the "Admin Status" of the AP. It should be enable
2. Advanced setting page of AP, "AP Group name" set to be correct ap group. If you haven't create any additional ap groups it should be in "default-group"
3. Also check in the interface tab of the AP configuration both radio 0 & radio 1 interface Operation Status is UP

E1000 works behind E3500 as access point but not behind Airlink AR675W and ideas?

In my own home just testing my E1000 works fine as an access point with an E3500 as primary router using Linksys
method 1 (lan-lan connection) with E1000 IP reset to 192.168.1.2 and DHCP off and with
method 2 (lan-wan) with E1000 IP reset to 192.168.2.1 and DHCP On and different wireless SSID.
In my daughters building where I need it, I cannot get the E1000 to work as an access point. The primary router is an Airlink AR675W with ip 192.168.0.1 (255.255.255.0) delivering addresses 100 to 150.
When i try the E1000 in either method I get no internet connection on devices connected hardwired or wirelessly to the E1000. Before each setup I used the reset button and the factory defaults tab
method1 (lan-lan) I set the E1000 to IP 192.168.0.2 to be different than the Airlink and DHCP off.
method2 (lan-wan) with E1000 IP reset to 192.168.2.1 and DHCP On and different wireless SSID.
Are there any ideas why I cannot connect to the internet in this way behind the Airlink primary router

ok - i will read up on the airlink - it is a landlord situation but he will probably let me do a few things to it.
Also I see the Airlink admin IP default is 192.168.2.1 and not 192.168.0.1 like I thought so that might make a difference.
I don't know what flash DD-WRT means. Its a 10 minute drive to the other house. The internet provider is SHAW cable and I do not know the modem but it is probably Motorola SB5100 or SB5102 wired modem. The problem is it is a large house with concrete walls & floors & double pane windows so the wireless signal downstairs is weak. ethernet cables are probably ok but I'll take some more with me. The ethernet jack downstairs definately works as I can connect a single PC to it.

3502 access point will not connect to 4400 Series WLAN controller

I recently upgraded our controllers to the latest version 7 software, as I read this was one of the requirements to get them to connect. But I am not having any luck getting into a controller. Normally I plug them in to the network, they pop into the controller listed as something like AP5057.a844.xxxx and then I can finish configuring them, but a static IP on them, etc...
This is the first of this model AP I have tried to deploy, so I am wondering what is different with these. or what I might be missing in the default config in the WLAN controllers.
Niether of which are set to "Master" either.
Thanks in advance, Tandrist

Hi,
The 3500 as you mention are supported on code 7.0
To get the access point to join the WLC we have different options.
If the access points will be on the same subnet as the WLC then you just need to get the APs to get a valid IP address from the DHCP server and once they have an IP address they will join the WLC because they are on the same subnet as the WLC.
If the access points are on a different subnet then the WLC you will need to have a DHCP server configured to give the unit an IP address and use option 43 or DNS so that the APs can send the join request to the correct WLC on a different subnet.
Or if not configure the AP via the console port with the static IP address and WLC IP address.
Also make sure that you have the correct country code enable on the WLC, and that the APs you purchased are the ones to work in this country, because if not the AP will not join the WLC.

E2500 as an additional access point will not connect

Hello,
I have AT&T Uverse which provides Internet for my home. The wireless capability of this router is pretty bad, I don't get good/reliable wireless reception upstairs in my office. The solution was to buy a Cisco E2500 and add it as an access point upstairs.
I have the E2500 LAN port connected to the LAN port of my uverse router downstairs. DHCP is turned off on the E2500. I have my office PC wired into the E2500. The home PC works fine, its getting DHCP from the uverse router downstairs and connects and good speeds. The problem comes with my wireless devices trying to connect to the E2500.
I should mention that yesterday when i bought this, all worked fine. This morning when I came into my office none of the wireless devices would connect to the E2500 at all. But as soon as I remove the cable that connects the E2500 to the uverse router downstairs they will connect via wireless but of course not get an IP address since that is disabled. No idea what is going on here.
I have factory reset the E2500 and uverse router several times and am getting no where. Any ideas what could be causing the wireless devices to not connect at all?

I think you are having problems because you didn't give the E2500 an appropriate static IP address outside of your Uverse gateway's DHCP range.
A better option would be to reset the E2500 to factory defaults and then follow these bridge mode intructions:
http://www6.nohold.net/Cisco2/GetArticle.aspx?docid=28cee6a2fb0d4176a2210942d1d5836c_Setting_up_the_...
You should give the E2500 seperate (different names) SSID's and make sure your wireless channels are different on AT&T gateway and E2500. Use 1, 6, or 11
The best option, however, would be to reset the E2500 to factory defaults and use the IP passthrough feature on your AT&T gateway. If you use the IP passthrough feature on the AT&T gateway, you would use internet connection type DHCP on the E2500 and it would be functioning as a NAT router. The IP passthrough feature on you AT&T gateway allows your E2500 to receive a public IP address and you will be able to avoid the AT&T gateway's NAT. So you will just be using the E2500's NAT. You will need to change the MTU to manual and you can ask AT&T what the appropriate mtu is for Uverse.

Setting up Time Capsule as "Access Point" and not using router feature

I would like to use my Time Capsule as a wireless access point for a laptop. What settings in Airport Utility do I need to make?
Here's my setup:
Internet -> DSL Modem -> Linksys (wired) router -> Ethernet Switch -> Time Capsule.
Connect Using: Ethernet
Configure IPv4: Manually
IP address: 192.168.1.20
Subnet: 255.255.255.0
Router: 192.168.8.1
Connection Sharing: Off - Bridge Mode

Follow up to my question.
Got my laptop to access the internet via the Time Capsule. How? By having my ethernet switch connected to the WAN port of the Time Capsule - not the LAN port.
Internet ->DSL Modem -> Ethernet Switch -> Time Capsule (WAN port)
I noticed that makes it so computers on my wired LAN can't use 'Airport Utility' to access the Time Capsule. I have to move the ethernet cable from the ethernet switch to a Time Capsule LAN port, in order for my wired LAN computers to see my Time Capsule.
Is there a way, so I don't have to unplug from the Time Capsule WAN - to LAN port?

WRT 54G conected to access point but not internet

Hi There
The wireless router is working an can get to the internet on PC
My other PC see's the access point but
will not connect to the internet
Signal strengh andLink quality are good, looking at the
PCI Linksys adapter box
any thoughts?
Thanks

Whats the OS installed on your computer. In the system tray you will find the linksys monitor...right click on it and select "Use windiws XP configuration" ... once its done ... next to that you will find "Wireless Network Connection" icon ... Right click on it and select "View Available Wireless Network".... select your network... when prompted for "Network key" type in your security key and click on 'Connect' ... After this see if you are able to go online or not.

I have an airport express, which I want to use with my broadband providers router to create a second wireless access point but not with the same network name etc.

In effect, I want to have my providers router working upstairs and the aiport express downstairs connected via wi fi. The airport would have a different network name, then allowing me to connect the children to the access point. This would allow me to turn their network off at times of day etc.
any ideas ?

Sorry, but the AirPort Express....or any other Apple router......cannot do this.
In order to do what you want, you will need to establish an Ethernet connection from one of the LAN <-> ports on your "main" router to the WAN "O" port on the AirPort Express.
Configure the AirPort Express to "create a wireless network" using a wireless network name, and password that you select. As far as controlling connections, you can use the settings in Timed Access to establish rules about when the kids and cannot connect.

Power point slides not showing

I have a rather odd problem. I've got a lengthy pdf which I converted to jpg's. I pasted those jpg's into power point into and then imported the pptx into Captivate 6. All the slides import but only the first 2 jpg's are visible. All of the other slides are blank. I know there's an easier way to do it, by converting the pdf to a pptx, and then import to captivate, but the pdf is mostly text and the text gets jumbled during the conversion. I'm just curious as to why the jpg's are not coming into captivate. And btw, I've also tried it using png's.

If you already have JPG images, why not simply use Captivate's ability to create a Slide Show and just create a project and point at the images?
Cheers... Rick
