Cisco Wireless :: Can't Console Into 1252 AP And All 3 Lights Solid Green
Jan 18, 2011
Recently we had a situation where our users were unplugging one of our un-mounted 1252 LAPs. They would do this so they could borrow the wire to direct connect any one of their devices not realizing they were disconnecting a wireless access point. After discovering that the AP was unplugged once again, our admin plugged the AP back to the network but noticed that it no longer would connect to the controller. We can no longer console into the AP but can console into all other APs we have. All 3 lights are now green. Radio and Ethernet are solid and Status is blinking. I found the Cisco doc explaining the meaning of the front panel lights but have not found this particular configuration. What these lights mean and why not being able to use the console port?

I have a DIR-615 v e3 router
Did a bad dd-wrt flash and now all it does:
-no power light
-solid green lights: WAN-L1-L2-L3-L4
tried to go to recovery mode (power on while holding reset switch).....does not work.my search on the internet revealed, that after bad flash, power light still comes on, maybe as orange, maybe blinking, or just blinks once

I've not found any topic related to what happened to me. Bought two cameras and upgraded the firmware on both as asked, but one of them just stopped. The light is solid green and not red like other posts.Tried the recovery procedure, but the browser won't find my camera. Changed computer IP and everything else that was told to be done. Nothing works!! I also can't find any posts relaled to my problem all over the internet.

I have 2 - WS-C2960-24TT-L switches. Both are experiencing the same issue. Upon booting them up, all lights flash on the mode indicator panel, then it goes directly to a solid green "SYST" light. Nothing registers across the console cable. I have tried different baud rates, cables and computers. None of the ports come up regardless of how long either switch is powered on. Holding the Mode button during boot up produces the same result, nothing. Sounds like they are dead, however, I thought this would be the place to go for ideas. Can I revive these switches?

Here's the setup I have:
iMac (Aluminum)
Apple Time Capsule 1TB
AT&T DSL
When connected, all lights on modem are green, so is the light on the Time Capsule. When I go to a website, page cannot be displayed. When I insert the ethernet cable directly into the back of the iMac straight from the DSL, the internet works just fine.With all lights green but no internet connection, what am I missing?

There was a problem with one of our servers. We were unable to connect to it remotely. We restarted the server. Still we were unable to communicate with it. Static IP is provided.
In the connections settings, it showed the send and receive as 0. I noticed the network card lights. Both were flashing green in sync, like twice in one second. I removed the cable and funny thing was, it was still blinking non stop in the same way. I plugged the cable back in and took back out, the same result. After a second restart of the server, it started working normally and i was able to communicate with the server.

I am replacing an old Catalyst 3550 (that has 2 Gig ports) with a 3750 (that has 4)- I used the exact same configuration in the new switch. When I plugged in the new 3750, the trunk ports started blinking from green to amber. I dont know why this is occuring- it SEEMS to be fine, but we havent thrown a whole bunch of traffic over it.

Thinking back, about a month ago I updated the firmware (I can't check version at the moment). The switch has been working fine since then. Today I needed to move some power cables and the switch lost power. Now ALL of the LED lights are flashing green and I can't access the switch. I've tried setting a static IP on my laptop to 192.168.1.20, mask 255.255.255.0, and accessing the switch on 192.168.1.254, but there's no response. I've tried holding in the reset button for at least 30 seconds while the switch is powered on, AND while powering it on. None of that has worked. Also when I first power it on, the system LED flashes orange very quickly for a second or so, then all of the LEDS start flashing green.

today I received a Cisco 1841 Router with a problem i have never seen before. Maybe this my 1st really,really broken Cisco Router. When I power the Router on, the fan and all lights turn on (green) and that's it. Nothing changes, also after minutes of wating. On console i don't get any messages and I already tried every BAUD rate possible. Switched the router off/on again and again. And no, it's obviously not a console problem of my computer, because i tried with different routers.

I can not fix the problem with the router. I power it up, all is GREEN, then it blinks RED, then GREEN, and finally RED. The router is terminally not connected to the Internet. How can I check if the router is BAD. I have done all the troubleshooting, examples:
connected ethernet directly to computer - no problems
attempted to fix problems via belkin software
changed channels on modem
updated firmware
etc, etc

I'm trying to connect a PC to my wireless network but am having issues. Using both a trendnet wireless N PCI network card and a Linksys G510 wireless G PCI network card I have the same issue whereby the connection, an unprotected mixed (B,G,N but have tried only N on the trendnet) wifi, appears in the Windows 7 connection list but upon clicking "connect" I am told Windows was unable to connect to the network, and then the network dissapears. Later on, it will randomly appear and will stay as such until I try to connect.
I've tried using an Asus wireless N 150 USB adapter with the PC, the problem is different. I can connect to the network and the connection will appear fine in the taskbar, but trying to open a webpage either does not happen or is excruciatingly slow.

We have a root AP whose status light is showing solid red. We power cycled it and it still shows solid red. According to the Cisco documentation, this indicates a firmware failure. Unfortunately, we did not get Smartnet with this access points and instead opted for the limited lifetime warranty.
My question is: is there any way to fix the firmware via console? Whether it be through xmodem or what not. I ran debugs on the controller and can confirm that the AP is not communcating with the controller.
It is also weird that the mesh APs that were previously connected to this root AP show a solid red on their status lights and green for their RF LEDs. Shouldn't the status LED be flashing green-amber-red?

I have a single WRT54G v5 that has treated me very well over the years. I have too many devices right now and I'd like to throughput of N, but have failed to find one that is measurably faster or as stable than my current equipment. Most recently I tried a D-Link DGL-4500 and regardless of hours of configuration, research and support I was left with slower-than-expected speeds and dropped connectivity about once a day.
I want to be able to stream media to all 3 BoxeeBox's simultaneously while browsing the internet on a few of my devices and I don't want to have to reboot my router daily or even weekly.
So far I have come to a preliminary conclusion that a solid setup for me would be a ZyXEL ZyWALL USG20 and 2 to 3 Ubiquiti UniFi AP's. While the USG20 does intimidate me, I have several solid network admins that have told me they'll set up the network for me and walk me through it.

Recently in the morning the router will have lost ability to connect to internet <internet light is on> and I cannot access the router page <sys light solid> from either wired or wireless connections. Why is this and will it be solved if I upgrade firmware?

I have 3 1142N AP's. I plugged them in one at a time here at my desk and they work fine. When I take them upstairs and install them only one of them works. I can move the working one to the other locations and it still works. The LED flashes continously green on the other two.

I am replacing an older AP with a new 1252 unit. I attached everything and powered it up, but my DHCP server does not appear to be finding it and assigning an IP address. The status light stays green and the ethernet light blinks randomly green. Seems to be connected fine, but without an IP I cannot configure it to use it.

an Aironet 1252 which is failing on boot. When power on the access-point shows the error below.
WARNING: A memory error occurred during the system start-up self-test. The device must be serviced if the error persists.
The following commands can, optionally, be used to initialize the flash file system and the TFTP file transfer system:
But when this happen, I can start the IOS manually doing flash_init and boot in ROMMON. After do this commands, the access-point starts and works normally.
How can I check and correct the memory and solve this issue?

we want to have full wireless coverage in a big warehouse (120mx90m) and 15 meter Height that will be having big racks (14 meters height) and 2 meter between the racks and the rack itself is 1.5 meter (2 rack back to back), now we will be having scanners and we need to make sure the wireless is covering everywhere.Where is the best place to put the AP, Ceiling? How Many APs per row ? each row will be around 60 meters length.
Is AP 1252 a good choice? The scanners are a/b/g.What i'm thinking of is to put 1 AP per row mounted on the ceiling and antennas facing down because it is hard to mount the APs between the rack because of the automated racking system.

Currently my company has 1 primary SSID that is used throughout both floors of the building. We have 1252 LAPs which have 2.4 and 5Ghz antennas. I'm not sure if this issue is only with XP or perhaps it's the computer's drivers but we run into problems with end users going to a different location and having a very weak signal or nothing at all, yet coverage is fine. I believe the problem is the end user's machine selecting the strongest signal and it I have the feeling that switching bands isn't being done as it should when it's in range. So my question,
Should I split up our 1 SSID and created multiple SSIDs according to the location and include 5Ghz or 2.4Ghz in the SSID name so it's easier to ensure that users are connected to the proper signal? I want to ask if multiple SSIDs would still enable users to freely roam (as long as the ssids are configured) throughout the building without noticing a loss of signal but currently just having 1 SSID isn't really enabling people to freely roam around without connection issues.I don't believe having multiple SSIDs will be useful for the computer's choose their connection any more efficiently but allowing the user to manually see what they're connected to and pick something better according to their location.

I am configuring a mobile van that is used for a mobile health clinic to drive to several locations and when pulling into an allocated parking spot the van will connect via wireless automatically. I am using autonomous 1252 AP's and am considering either briding or workgroup bridging.
The issue I am encountering is that the AP inside a van is a router that has to do DHCP across the wireless and because the ethernet interface between router and AP in the van never goes down the router does not know to re-DHCP. I remember from way back there was an IOS command to track a serial interface and drop the ethernet if the serial link goes down. Is there an equivalent command for AP's to drop the ethernet interface if the radio interfaces go down?

I am using two Cisco Aironet 1252 (cisco AIR-AP1252AG-A-K9) to setup a point to point link (one is configured as root bridge and is as a non-root bridge). Both Aironets are running software version Version 12.4(25d)JA.
Is there a way that I can that I can perform an antenna alignment test on the Aironet that is configured as a non-root bridge?executing the following command dot11 dot11radio 0 ? does not show the antenna-alignemnet option.
