Cisco Wireless :: CAP3502I Not Responding For Traceroute_tracert
Oct 18, 2012
I have 1 cisco AP (CAP3502I) which is not able to associate with WLC (version 7.0.235.0), using CAPWAP. Simply from debug I can see that AP is trying to contact WLC on port udp/5246 but can't see any response from WLC.
*Oct 19 07:06:50.055: UDP: sent src=x.x.x.x(4271), dst=wlc.wlc.wlc.wcl(5246), length=47
AP is getting config about WLC from DHCP option 43 and have own reservation to get same IP address (+default GW). AP is NOT associated but as it has IP address from DHCP then it is pingable. But don't know why, but I'm not able to tracert/traceroute to this AP, as I can see it is getting packets but it is not responding.
But on different locations, where are same APs model (associated with WLC) I have no problem with traceroute it, as APs are responding.
My question: It is not related that AP is not able to associate with WLC (still working on it) BUT should I be able to traceroute/tracert to unassociated AP (to his IP) and get response???
NOTE:
==> WLC is in DC and AP on one location, so diagram could be: WLC ---- L3 device ---- Provider MPLS router..........Provider MPLS router ---- L3 device -- L2 switch --- AP (CAPWAP)
@It means that there is NO FW on tha way :-)
I check many other APs with same model and non of them has problem to respond for traceroute, but this particular unassociated one has :-

This summer the IT department at my location rolled out a little more than 100 AIR-CAP3502I-A-K9's to much success. We have had an issue with only one AP. This paticular AP must have gotten unplugged during the updating process after the initial conneciton to the controller was made as the LED currently blinks red-blue-red, indicating an error in the flash memory according to the manual.

We've just replaced some 1240 LAPs with 20 x 3502i.
Seem to have a problem, most of the 14 * 3502i have regersted on the network and working, 6 arent connecting and log below. I've replaced one of the AP with a differnt one, same model and batch and this works.
WISMs on 7.0.98.0

I was under the impression that the AIR-CAP3502I-E-K9 is a ceiling mount AP only. Is any one using these as wall monuted AP's?

Can i run both 2.4 and 5ghz at the same time? so my N user's can connect at 300Mpbs on the 5ghz bonded, and my G users can connect to 54Mbps?Also i ask because of coverage, my 5ghz does not cover as far as the 2.4 so those at the extremity's could at least get G with a good signal?

I'm wondering if there is an easy way to change the regulatory domain on a lightweight access point. The reason I'm asking is someone accidentally placed an order for AIR-CAP3502I-N-K9 access points instead of the AIR-CAP3502I-A-K9 flavored ones. I can see how it happened, since undoubtedly someone asked for the "N" access points, thinking 802.11n, and the other person was thinking AIR-CAP3502I-"N"-K9.
do I have to RMA them, or is there a way to magically turn them into the ones flavored for the Americas?

ragarding AP AIR-CAP3502I cannot learn option 43 from MS server but it can learn the DHCP ip address. We have 2 sites that option 43 does not learned by new AP's but other site works ok. I tried also to delete and add the dhcp scope and same issue. My temporary solution will be creating the DHCP pool with option 43 and 60 in the access switch and it work ok, new AP's able to show in the WLC. I just need more information why site AP's cannot learn the option 43 of the MS server but other site AP's work ok. Is this IOS bug? AP's issue? MS issue?

I have 10 new AIR-CAP3502I-A-K9 connected to a WS-C3750X-48PF-L switch. 8 of the APs power on and connect perfectly, but two are problematic. Both devices are granted power, but they never go past the stage of getting power from the switch. A look at POE shows: [code]
Where the AP that is not working is connected to Gi1/0/4. The interface shows down/down. I've tried shutting the interface, removing power, cdp etc.
Are there any other tricks you can think of to get it working or would you say that it's 2 faulty APs? I am not based at site unfortunately so I cannot console to the APs and check them out.

We have a Cisco 1522AG configured as a MAP in our production network. Last week the AP went down. On investigating it keeps rebooting itself. constantly showing 4 orange leds, Maybe cant find the WLC? Is there a way to console into these devices to see whats happening in the background while its booting up or even reset it back to the factory defaults?

We are running two WAP4410n devices in our office. One of the devices recently appears to have died. No ethernet, wireless, or POE lights passing packets, however the power indicator stays on steady. Have attempted a direct connection to the box straight from a computer with both straight and cross-over cables. Device will not even do a factory reset via the reset button.Device cannot be reached via web-interface either.

I reconnected 4 laptops today on 2 different WAP4410n APs. The user will let me know if they get disconnected. Yesterday I even reflashed the firmward on them. Also in order to reconect to one of the Waps I had to cycle the power.
The laptops are different One is a Dell Latitude c840 w/ Links wireless card and the other is a IBM t41 i believe.

Just bought 2 of these (wish I had seen this thread before). They shipped with the latest firmware already on them, so must be a very recent manufacture. I am having the exact same problems as above. It seems to be almost exactly 24 hours for me and the access point stops passing traffic. At first the latency goes very high (2200ms - 3800ms) right before it stops passing traffic. You can still ping the access point from the 802.11 side for a while, but nothing from the wired side, it just goes braindead. Once I was able to get the management interface up over the wireless while it was in this state and rebooted from the management side. It did not solve the issue, I had to unpower it and restart it (PoE Powered). I have only configured one of them due to these issues. I think they are going back. Here is how the access point arrived (yes, I just rebooted again for the 8th time).

I have 2 of these in a Bridge between 2 buildings. Cisco support replaced them with 2 BRAND NEW units after 6 weeks of waiting, that do the same thing. Spent so many hours on these turds it is insane. the thing goes down with the wind, tinker with it and maybe you will be up for a few hours or days then back to down again. Thinking it has something to do with the firmware or a power saving thing. Works great when it is up though. I am still trying stuff to get it to work stable. To much money invested in them now to start from scratch but they wanted budget equipment in place and not Cisco Aironet.

With over 45,000 views, something must be wrong. Like many of the others here, we can't work out what's wrong with our network and why the cisco 4410n behaves so badly.
Our experience is just like everyone elses. At some point in time, mainly between 1 day and 1 week, the router just stops responding. The problem appears to be on the LAN side, as quite often when it fails, the wireless is still active and clients are associated. Some time ago I was Cisco certified, so I have had faith in Cisco products. I also sold them for a living, which made it a natural choice, but I am struggling to come to terms with my purchase here.
I had tried:
All the latest firmwares from March until now (including the latest) Full resets of the device, including "reset to factory defaults" Pegging the autonegotiate to fixed 10/100 Changing channels on the wireless (although as mentioned, it appears LAN side issues)
This thread has given me different views. Other sites also talk about changing beacon settings, but I'm not sure that's the right way to go.I would consider syslogging the results and getting extended debug happening, but when the problem happens and the device hangs, LAN is lost so the messages are also lost.
I find it hard to believe that so many people can have this problem and no one at Cisco can reproduce the fault. So, here's a pretty simple network for Cisco to experiment with which clearly has the problem:
Flat GBit network
Dlink DGS-1016D 16-port GB switch (unmanaged)
4-5 wireless clients (mainly iPhones & iPad)
The volume of traffic is low - no huge file transfers. The expected uptime is between 3-6 days. As a matter of interest, I also tried POE to drive it using a TP-Link injector. The device worked perfectly, but the problem did not seem to be affected.
It might be heading towards time to log a call on this. I was hoping the vast number of existing callers would have given the support staff enough to solve the problem, but it appears Cisco is none-the-wise on the fault, let alone the solution.
As a matter of interest, maybe a good interrim solution would be for Cisco to use the watchdog timer to ping a known address and perform a soft-reset if the address (on the local network) did not respond after a period of time. This atleast would stop people having to crawl under desks and pull plugs to reset the device as it has no power switch.
I have a "Generation 2" device.

I have the same problem with my two WAP4410N connected to my Cisco SRW2024 Gigabit switch.It appears that there would be a time where the PHY's between the WAP and the switch are hung.The lights on the Gigabit switch are constantly flashing.
It is until I disconnect and reconnect the network cable between the WAP and the Gigabit switch that the problem is momentarily solved. Then it seems like another high traffic usage of the WAP will cause the connection to hang. This solutions is totally unacceptable as I am not willing to open my wiring closet every time to fix this hang. Also I've lost precious data between my client and server because of this hang!
I don't think the problem is with the Gigabit switch as I have other Gigabit devices connected to it and I never get them to hang like the WAP.
I saw on the release notes (although the firmware has not been posted) that there is a problem with the WAP Gigabit PHY. From the release notes, it seems the firmware will have an option to take down the speed of the WAP Gigabit PHY from 1000BT to 100TX. This would be a shame if this is the final solution as one main reason for purchasing the WAP4410N is its Gigabit capability.
Being a networking PHY designer who had also worked on other Cisco products, I'm surprise that this problem had not been resolved in their qualification and interoperability lab.

We have a situation with 20 4410N's They are connected through a 2960 switch. They runned for about a year with no problems. We use the WiFi system with 10 cisco wireless ip phones, several workstations (5-10) and a few mobile devices.
Three weeks ago we took 10-15 iPads in commission (almost equally divided over the AP's), since then the trouble started. Several accesspoints stop randomly responding a few times a, day. We updated to the latest firmware (2.0.4.2), but that did not solve the problems.
Were using 3 SSID's WPA2 encryption and fixed IP's for the AP's. If we can't get a hold on this we have to replace all the AP's by other ones.

My internet works fine but after a random period of time, usually 20-30 minutes the internet stops responding. I have ran a diagnostics test using the Intel PROset/wireless tools program and it states on the ping test that there is no response from the default gateway and the DHCP server.

I have not done the firmware for the units yet but have had only 1 outage thus far (but I think it was a power issue over the weekend).What I have done, 3 weeks ago, is put external antenna's on the 2 units which are 15 feet apart at 15dBi.The output is 40hz and I changed the latency time settings on the main unit, leaving the secondary at factory.This seems to be working for me so far. Usually goes down over the weekend and have to reset Mondays,but not this week. I am afraid of running the firmware because then it may become unstable again.

I have E1200 wireless router and it was working nicely for the whole last year with 2 mac laptops hooked up on it. About 2 months ago there were 1 mac,1 win laptop and a network printer. And again, it was working just fine at the beginning. I'm not sure when exactly it happened first, but now after working couple of hours internet gets off and router stops responding. If I try to reconnect to it from my laptop I just see an error message saying something about "Connection timeout". Also I don't know does it have something to do with the network printer, btw it's connected to the router via ethernet cable not wireless. Anyway, the only solution I've found so far is power off the router for a couple of secs and power it on again, which is obviously not a solution at all, it's annoying and not practical. The time it works fine before it dies is also not fixed, it might be even 10 hrs of working and sometimes only 1-2 hrs. My other suspicion is firmware. I upgraded it almost at the same time when new laptop and printer showed up. Maybe I have to downgrade it, but I couldn't find older version of it. It was HW v. 1, SW v.1.0.00, and now it's HW v.1, SW v.1.0.03.

I have a wireless router and I'm trying to user UPnP feature. of course it is enble in the router.
It's working one and after it stop working, looks like the router is not responding anymore. If I got on the web interface of the router, I loging, on the first web page I press save changes, even if I didn't change anything, the UPnP feature work again.
Looks like a timeout occure or something like that. Is there a way to wake up the router without having to go on the web interface? Why it's stop working?
Firmware Version: v4.30.15
