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.

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.

2702-UX-K9 Access Point will not associate with controller.

Hi,
I recently purchased nine new 2702 APs. Two of them will not associate with the controller. I realized they they had a different part number. They ended with UX-K9 instead of -K9 like the others. It turns out that these are new AP that are universal for any country. They APs find the controller but need some sort of password to pull the config down. I"m not sure what this could be?

Rasika,
I have the same issue on my home 2504 with these 2700 UX, I have tried code 8.0.100.0, 8.0.110.0 (Docs say this is the min version supported), and even 8.0.115.0 (latest available) still no dice. The AP won't register, and gives the error stated above. I am seeing 2 images available for the AP, the AP shipped with the later image but I AP recovery isn't working because it say's unable to find image with XX in the name? I see the TFTP logs, and name the file accordingly no dice, then the unable to find file name -XX pops up too. As you know I am busy during the day this week, but let's jump on a skype and take a look later maybe you have seen something I haven't?
For good measure, also attempted to join a 3650 here at the house IOS-XE 3.6 no dice, going to try 3.7 too tomorrow, It worked for the 3700 UX AP's we had??

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.

Access points will act as dhcp

Hi,
I am using static ip for all the systems.And installed 1131 acees point in automouns mode with the switch.I don't have dhcp server,can access point itself will act as dhcp server.To lease ip addres to client's

Yes i have a router
But i don't want to use.So i have a doubt whether access point will support r not.
Thank for reply..

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

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.
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.

Your AP-manager and management interfaces is mapped to port 1:
ap-manager                       1    80       10.41.80.2      Static Yes    No
only APs connected to port 1 will work.
You need to either use a switch and keep port 1 connected to it while APs join through the switch or you need to create a new ap-manager interface. not even sure if you can map it to the same port or different port! not even sure about the management interface!! it is mapped to port 1 and should be reachable anyway. it is a mess!!! have you read the best practice document that I put the link for earlier?
So you need eventually a switch to fix your issue. direclty connected APs are not recommended.
I am still not knowing how Cisco provided such swtich that is supposed to handle direclty connected Aps while it does not provide a smooth way to do so.
Use a switch and everything supposed to be fine.

Reset the TC to factory and start again.
Use all SMB type names for wireless and base station.. Not apple type names.. this is more important since Mavericks.
I also recommend different names for the different bands.
So for example.
TC name.. TCgenx (I use whatever the generation number is for the x.. eg TCgen4 or latest one TCgen5)
WIreless name.. TC24ghz for 2.4ghz
TC5ghz for 5ghz
You can also set the channel manually.
If you still have issues.. start with no security and then if it fails to connect there is something seriously wrong with the laptop. Did you upgrade install Mavericks?? That can lead to driver issues.. I would recommend a clean install.

Both my iphone 4s and my ipad3 will not connect to the server when trying to access my email account. Why, and how do I fix it.

Since 29/10/2012 my iphone 4s and more recently my ipad 3 will not connect to the server when trying to access my email account. All I get is an error message saying that 'cannot get mail, connection to the server failed' I hadnt changed any settings it just happened. I have since done a complete re-boot on the ipad but to no avail. Anybody got any suggestions?

No. Everything was working fine and then it wasn't. I hadn't changed any settings or switched either one off. When the phone stopped working properly I ignored it because I always have my ipad with me but that just sopped working properly and now I am stuffed. I have tried most solutions suggested on here even wiping the ipad clean and re-booting. I did this exactly the same way as when I first got it but still no joy. The same with the phone.

Firefox will not connect to certain major `websites" Why? I can go to Google and access

In the last 4 days Firefox will not connect/find certain major websites. Basically says that server not found.
What's the deal here? I use windows 7 and have the most current
firefox update.

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

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.
