Cisco Wireless :: Aironet 3502i Adapters Not Allowing Hosts To Connect
Oct 21, 2012
We recently had the Aironet 3502i APs installed in our infrastructure and are having a bad time with hosts connecting to them. The controller sees them, they have an IP, they are showing a solid green light, but you cannot get devices to connect. If you reboot the device you get about 5 seconds of connection and then it disconnects. The only cure seems to be rebooting the APs, but I am baffled why this keeps happening. The installer is blaming our devices, but it is happening to laptops, thin clients, and even cell phones. From what I've seen, everything works fine until, i believe, the device tries to refresh it's lease and is unable to do so.

I'm new to this site, fully Microsoft certified but only just getting in cisco and looking to pass my CCNA later this year. Actual commands and general use on Cisco's im quite good at but general networking knowledge on networking (subnetting and network layers) I kinda suck at so will be studying a lot on this side of things[CODE]

I just configured Aironet 3502i and it works ok but no lights. I could see the AP in switch, in WLC, and in WCS and ping ok but when you see it mounted it has no light. I tried to shutdown the port in the switch and I saw it turns green (booting), once it was registered in WLC the light will be off.

EA4500 Linksys router stopped allowing vizio Internet apps to connect from two different TV's. Problem, Just got brand new EA4500 router and Motorola SURFboard DOCSIS 3.0 High-Speed Cable Modem Model: 575319-019. I have 2 new vizio big screen tv's with internet apps. All was working fine and had no problems but occasional drops or limited access.
One day BOTH TV's could no longer connect. However, The tv's will connect to another access point. therefore the problem does not exist in the TV/s and has to be a problem in my access point (I.E. Router allowing access). Additionally, all other devices connect and work fine. I have already unplugged everything for an extended period of time. Checked for updates on firmware and verified no software needed to be updated. Rebooted router... Am using wpa-psk and feel i shouldn't have to go weep as it was working fine...

I've got an 1841 router acting as the firewall for a LAN. It also does NAT and acts as the dialer for a PPPoE DSL line to the internet.
All is working fine, except now I need to allow a Tivo device to connect to certain ports on the Tivo servers on the internet. I want only the Tivo to be able to do this. The problem is that NAT is happening before my outbound ACL is checked, so even though I've got rules to allow the Tivo's LAN address out on all ports, it never works. I've verified this using a syslog server, and can see my external DSL IP trying to connect to the Tivo servers and being denied.
I've done things like this at work by NATting the appropriate internal host to its own external static IP address, which allows me to write rules allowing only that external address to do stuff. But I don't have multiple external addresses to work with here.
I tried applying my outbound ACL to the LAN interface of the router in the "in" direction (and removing the same ACL from the Dialer interface in the "out" direction), but that broke other things like the router's own ability to ping out to the LAN or to see a TFTP server on the LAN. I could maybe fix all of that with rule changes and inspect statements on traffic going out toward the LAN (not sure of this, think so), but I'm wondering:
Is there a better way to let just the Tivo makes outgoing connections to certain ports?

There is a problem with my WLC, it is not allowing an specific client to connect. It gives an 802.1x failure log but I am not using it, anyways the WLC puts this client in the excluded clients list and I didn't add it manually, in fact is a new laptop.
I attached a couple of screens from my WLC.
IOS is 7.0.98.0

I am able to connect to my Cisco ISR 891 via VPN with the Cisco VPN Client 5.0.07.0440, but once connected I cannot access hosts on the inside. If I ping a host on the inside by name, nothing resolves. If I ping by IP, I get a reply from the public IP of the router. [code]

I have recently bought two 1800 cisco routers and have tried to connect them over wan serial link, but I am having problems when trying to access resources on the other side. I am a newbie to cisco and I wonder if the problem is with the configuration or the new routers or the serial link between the sites. Below is the show-running config results I have done on both routers; I can ping the serial interfaces from both sides and remotely, but I can't ping hosts or FE from other side.

I have a nac guest server 3315 appliance with 4 NICs. I want to connect each NIC to 4 different networks without allowing traffic between them. So RADIUS interface will be different from sponsor/admin interface to the NGS. how to achieve this. I have created and assigned a static IP address using system-config-network, but when i do ifconfig i dont see the remaining 3 NICs and the web interface doesnt seem to have provision to create this interfaces.

I have created a RA VPN with a 5505 using Anyconnect client. My VPN functions perfectly, but now I am trying to limit access so that only one single host on my network can connect. To do this I tried creating an ACL permiting the host and denying all other traffic, but it does not work it seems every one can connect. how I can limit the outside access to a single host?

My internet speeds are 45 Mbps DL and 1 Mbps UL and my various wireless connections (3 laptops in my household) were achieving speeds anywhere from 25-40 Mbps DL. My router started acting up and wasn't letting anyone connect via wifi so I did a factory reset and set it up the same way I did before (as best as I could), it started working fine again but now the speeds on all the devices that are connecting to at are capped at 18 Mbps. A simple speed test shows that no matter what they won't pass 18 Mbps, I am almost 100% certain this is the router and I was wondering what I might have done wrong or what is causing this.

Where I live there is no DLS or cable to probide me with Interent access so I use my Verizon 3G/4G smart phone (Android) as a hotspot. Right now I am using an old Vista PC and ICS (Internet Connection Sharing) to provide Interent connectivity to my home network and Cisco lab. This works fine but I must have my smart phone near the PC for it to work. When I go to other rooms, I end up missing calls and texts since I have t oleave the phone if it is providing Inerent access at that time. If I can get the Airnet's to connect to the hot spot AND provide Internet access, that will provide me additional mobility. This would also be good for small businesses as a backup Internet Connection.
Is there any way that I could elimanate the Vista PC and have my Aironet 1231G Wireless router(s) automatically connect to my phone's 3G hotspot to provide Internet access to my lan?
I have 2 Airnoet 1231G's running the c1200-k9w7-mx.123-7.ja IOS and a C3550XL layer 3 switch.

I have configure my AP with to SSID (11 & 12), but I cannot connect to 12. It authenticates, and while trying to acquire IP address from 12, it fails and connects me to 11 (if I have already saved the SSID connection).
The following is my AP status:Product/Model Number:AIR-AP1231G-A-K9 System Software Filename:c1200-k9w7-tar.123-8.JEE System Software Version:12.3(8)JEE Bootloader Version:12.3(2)JA4
The SSID 12 already have 4 clients connected, And I am tring to connect a 5th one (smart phone), but cannot connect to 12, instead coneected to 11. Also tried with a laptop, but cant get the IP address, and give Limited Connectivity error.

I have a BEFSR41 (wired) router. On the LAN side, I'm using all static IPs, and have the local DHCP server turned off. On the WAN side, I'm using DHCP. When I plug my laptop (which runs Windows 7, and has a static IP set up) into the router, sometimes I can't connect to any hosts on the WAN side, even though other machines on the LAN side can connect to hosts outside. If I run Wireshark, I see the following happening over and over. [code] When this occurs, the laptop can nevertheless connect to the embedded web server running on the router, and, there, I can tell the router to release and renew its WAN-side DHCP lease.

I recently changed the configuration of my Aironet 1140 from WEP to WAP2-Enterprise to make it more secure. I am using the WAP as the radius server. After making the change I connected my Blackberry to the wap as well as a Samsung Chromebook. However when I tried to connect my HP laptop it is unable to connect. Watching from the Aironet's console I see that it is processing the association and windows ask me to enter my uid and password. When I do this I get an authentication error. I have tried several times adjusting parameters on windows but it always fails. Here is the configuration of the WAP:
!
version 12.4
no service pad
service timestamps debug datetime msec
service timestamps log datetime msec
service password-encryption

I am in the process of deploying 3502i APs. This site has 2 - 5508 WLCs both running Software version 7.0.220.0 and 2 - 4402 WLCs both running the same version of software as the 5508s. All of the APs that I have installed so far have joined the controller and I can associate to them and access the network. When the APs first are connected to the switch they go through the 'normal' boot up with the LED changing colors - white, red, green, blue (not necessarily in that order). Once the AP has completed its boot sequence the LED goes out and remains NOT lit.
This is happening to most but not all of the APs. This is the first time I have deployed 3502s - previous experience is with 1142s and 1242s and the LED does not do this with them.
I can, through the CLI, turn the LED on but it is then ALWAYS blue, even if a device is NOT associated to it.
I do not want to leave them off because the account will believe they have a 'dead' AP and with them always blue they cannot properly troubleshoot using the LED.

I have a customer with several older Aironet 1121G WAP's. In one area of the plant the noise levels from several large motors is preventing reliable connection to the WAP, even though it is located in the same conference room as the users. I am suggesting upgrading the 1121G to the 3502I to take advantage of the Clean Air technology. This raises two questions:
1) Will a single 3502I be able to effectively handle the RF noise, or does it require a network of WAPs to function properly?
2) Does the 3502I require the CT2504 controller for the Clean Air to work, or will it function in a stand alone mode?

how to convert a 3502 access point from Autonomous to Lightweight ? 3502 has a new IOS released back in Dec 2012 to work as staandalone mode. I need to convert this back to Lightweight mode.
I have been searching on web but have had no luck so far with anything. Tried converting it to lightweight in the same way as putting it on Autonomous IOS but errored out.

When we were installing some new APs, were plugged in to ports that were not configured on the WLC management VLAN.
This is the illustration
WLC management VLAN is VLAN 80 Management VLAN of infrastructure (Switches routers) is VLAN 10
The APs were plugged in to VLAN 10 and they were not able to associate themselves with the controllers.
Through research, those APs were getting a wrong IP address,
I did the Mode button, pressed for 30 secs, but this did not fix the problem, i thought it was going to clean the flash and bring the AP back to factory default I do not believe this happened.
We also added the cisco-capwap-controller.localdomain to our DNS servers, and then I rebotted the APs and still no luck.
What fixed the issue is we had to go to the DHCP server, release the IP addresses and we found those based on the macs of the APs. What is we do not have the mac addresses?
Now that I have the DNS entry created, if I plug in an AP on the wrong VLAN port will I be able to see it?

I have a 3502i(AP_1) that will not join a 5508 WLC(WLC_1)(code 7.2.103). The 3502i(AP_1) will join 4402 WLC(WLC_2)(Code 7.0.230). I have another 3502i(AP_2) that will join the WLC_1 & WLC_2. I am using capwap discover through DNS and hard coding the primiary WLC to AP_1 & AP_2. When I debug capwap events and errors, I see the static capwap messages and replies. Both of the WLC are on the same subnet. I have defauted the AP_1 and it joins the CISCO-CAPWAP-CONTROLLER as expected. When I change the Primiary WLC to WLC_1 it goes back to the CISCO-CAPWAP-CONTROLLER. If i change the primiary WLC to WLC_2 it joins. If I change the primiary back to WLC_1 it joins WLC_2 even though it is not a secondary. I know the previous joined WLC are stored in NVRAM, so that might be why it is doing that. I can join other ap to WLC_1 just not this one.
