Cisco Wireless :: WLC 4402 No Boot-up Dead
Jun 22, 2012
I tried to upgrade the cisco boorloader pf WLC 4402 from version 4 to 7.2. I updated ER.Aes FOR 7.2 (EARLY RELEASE.aes). It was updated perfectly and then I rebooted controller....now i can only see blank screen from connected console.I tried the flash of other lan controller but its not working because the issue is in the ROM as the boadloader file is in the ROM which is corrupted now i want the solution to upgrade the boatloader file inside the ROM.

I wanted to upgrade our three WLC 4402 from software version 5.0.148 to 6.0.202.0. The upgrade on the first controller was working. Unfortunately he lost all the local management users and it's MAC filters, but restoring this was not the problem. After upgrading the second controller.... the device does not boot anymore! The alarm led is RED and I don't know what to do. The only way to get connected to the controller is via the console port. There I can see a "parse error" but I don't know if that is the problem. Please look at the "log" attached. I'm not sure if the red alarm led was there before upgrading the controller software because the device is located to another place. I'm really concerned about upgrading the third controller because it's the most important wlc.

Have to re-boot 1-2x daily. Updated firmware through Cisco, followed by about 7-8 support calls. They all recommend some sales thing, new router, computer update and clean-up, or blame it on my modem (not the case). When E1500 goes down, all wired and wireless connections are lost. They all recommend some sales thing, new router, computer update and clean-up, or blame it on my modem (not the case).

How do I troubleshoot to find out if my wireless router is dead? I have a WRT160N. It's been giving me problems lately, so I thought I'd update the firmware. Long story short, I had to reset it, but I still can't get into it. I have gotten into it, but when I try to save it gets hung and then I reload and then it starts all over again.It does work hard- wired--I can access the internet with ethernet. But I can't get the dang thing reset and then upgrade the firmware...
Somehow I set this router up to act essentially as a repeater, an extension of the wireless network that is "anchored" (not the right word I'm sure) by the wireless router provided to me by my DSL provider. I want to do the same thing once I get this one working again--set it up as an extension of the existing network so I can essentially walk around the house with my iPad and not have to re-log in when passing into a new "zone".

have a Cisco 5508 controller (version 6.0.199.4) that when I enable global multicast mode it will work for an hour or two and then it will kill the network. All internet both wired and wireless, access to server everything dead. I then have to directly connect to the service port and disable the global multicast mode. Then two reasons for enabling it are Docs2Go and LanSchool both require multicast to be enabled. I have it enabled on our wired network and it works OK there. ted.

I've got an IPTV network with Bell FibeTV with Motorola VIP1216 (the DVR master) and VIP1200 (slave) cable boxes. All the coax cables in my walls form a wired ethernet network instead of a cable TV network. To get better wireless coverage in my home, I've set up routers as wireless access points at each of the cable boxes. Essentially I've plugged the router into the ethernet bridge of the cable boxes, and disabled DHCP and gave it a static IP and did all things I needed to do to disable all the routing capabilities and make it into a switch (here's what I did, step by step: [url...]). So when I go from one room to another, I just select a new wireless access point to get maximum signal strength and speed.

It has happen suddenly : Internet is not working through WRT150N, though it work when directly connected to the modem. So I think it is a router issue :On the WRT150N, Internet light is flashing fast for 2 seconds, then is off for 2 seconds, then flashes, then is off and so on, wether there is a device (computer, modem, ...) plugged or not, through the blue ethernet connector.And sometimes, Internet light stays off from power on, whatever is done with ethernet connexions (yellow or blue).
When connected to the blue ethernet Internet connector, my pc ethernet lights don't blink (nor the link light or the data light)I have try the 30-30-30 reset cycle. But it doesn't improve.I have tried the loopback test : connect an ethernet cable from the one of yellow ethernet port of WRT150N to the blue ethernet of WRT150 N.Sometimes, the light for the yellow ethernet port goes on for a few seconds, while the Internet light continues to flash. After a few seconds, both go off.Sometimes, as soon as the loopback is made, the 2 lights go off, and if a computer is plugged to the yellow port, the ethernet lights of the computer and the router stays off.But I can access to WRT150N through Wifi and I can access to the web management.

I've bought my E4200v2 via eBay, because original Cisco store doesn't ship to my country (Israel).My first unit was... defective, I think I wrote about the issue on this forum a while ago.It had connection troubles, always in a dead loop, saying "Connecting..." one to 100 times it managed to connect, and suffered slow internet connection speed, where all speedtests gave me 60% of my actual internet speed.Which is 30mbit.I'm sure about my ISP, it uses next.gen technology, they have their own underwater optic cables. Without Cisco router, only dialer, I get 100% of my internet speed, or with another router as well.I decided to RMA my e4200v2.
Out of context question: Why there's no option to specify server name instead of server IP? our ISP uses domain name for connection, rather than IP address, as they have a lot and a load balancer above 'em.Now, to the original issue.Refund is no option, RMA again is no option, too much time and money.Maybe there is a solution? It just can't be the reality, that two out of two units are not working. I heard this router is very good. And I heard the v1 is working very well in Israel. so It can't be our country that is the problem.By the way, I've called my ISP and they've switched me to MPLS connection for a try, so in a router you just switch to "Automatic configuration - DHCP" and it pulls IP, DNS servers and connected to the internet, but was hooooribly slow.
So I'm back to dialer. the main still is the "Connecting..." loop, sometimes says "Connected" for a second, and then connecting again... It manages to pull DNS addresses though, but never the IP and never managed to stay connected.All the connection configs are very basic, you know it. Server IP, username, password, keep-alive, MTU (I've tried auto, and a ton of other combinations recommented by our ISP or Cisco).My latest idea was to film how I burn it or throw a rock at it and send to Cisco the video, but that's kinda too much, it's too early for such decisions, especially when already $300 were spent.

I am running Ubuntu 10.04 on my Acer Aspire One netbook.The wireless connection works great, but the wired is totally dead.
When I plug the Ethernet wire, the little led next to the port doesn't blink.
If I do ifconfig, this is the output:
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:1659 errors:0 dropped:0 overruns:0 frame:0
TX packets:1659 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
[code]....
There is no eth0. Is that normal?
In the "Network Connections" GUI there is an entry "Wired connection 1", its "MAC address" field is blank.
How can I make the wired connection work?

WRT400N worked great for 18 months.
Last week the Verizon-supplied DSL modem went bad (wasn't receiving data) and was replaced.
Now I can get Internet direct out of modem, and when I connect it to router the router's Internet light is on, but it seems to stop there. Devices connected to router via Ethernet or wifi don't get Internet.
I'm able to get to the router's admin console via Ethernet and wifi, but no Internet.

I have a simple question regarding dead peer detection on the ASA 5520. I am using a cellular VPN device to connect back to an ASA 5520 and I have noticed that the connection drops at random periods during the day. The vendor for the cellular device recommends disabling dead peer detection on their device, which I have done. The question is, where is this disabled on the ASA? is it the IKE Keepalive setting under the tunnel group option?

I have an old RV082 that I suppose has failed. The red diag light on the front panel is lit and nothing works. I've already replaced the unit, so I don't really need to fix it. Here's my issue: the setup on the old unit was pretty complex with a number of port forwards and other non-default settings. I'd like to recreate those items on my new router, but they were never written down so I don't know what they were. I've tried to connect a computer to one of the LAN ports, but they're all dead. Is there any way to get at the configuration page?

I just got a refurbished ASA 5505.It works fine until un need to reload it or unplug it from power en replug it, when I do this and it's warm (even after some minutes of uses, so still physicaly cold while touching it), in this case, it simply reboot in chain withing 1 or 2 seconds. I have to unplug it from power and wait 5 minutes before replugging it to power.
I don't know if it's a problem from the power supply (that makes some noise, but I think it's normal), I tried loading more the power supply by plugin in some PoE device (Cisco 7940G) and it works fine, so it looks more like it's a problem on the ASA itself.
Must I send it back to the vendor? I tried updating the ASA image, but this don't changes anything.

Is it possible my Laptop Ethernet port is dead?After I got home today I noticed that the store that passed by caused a short power outage. I knew this because several electronic devices that rely on constant power were reset.Next to be noticed was that my computer had no connection to the internet, and my Ethernet port has a constant orange light on.I proceeded to perform a full network restart for my modem, router, and computer. This solved the internet connection to my router. My roommate was able to connect via an Ethernet cable to the internet on any of the routers ports, but I was still unable.However,I was able to connect to the wireless on my computer. Unfortunately no matter what port, or cable I use my Ethernet port still is unresponsive to it all, and still has the constant orange light.you.Specs:Manufacturer: Gateway

After replacing my WRVS4400N Gen2 with a RV220W, I would like to know if there is a solution to resurrect the dead wlan, killed by the well known buggy firmware some time ago (I could not let it fix it in those days, cause some of use may need those devices every day, so "send it in and we fix it in some weeks" was a bad joke).
I do not need the "old" router atm, but it would be nice to have a backup device in hands, because the VPNs created by those devices are vital for my business. Is there a cheap way to fix this device, or would you say it would be cheaper to buy something else? (And after those two devices, I'm not sure that the next one would be a Cisco device again .

In a lab environment, I have a stack of two 3750v2-48ts switches. I upgraded the stack from 15.0(1)SE2 to 15.0(1)SE3 using archive download-sw.
Switch 1 in the stack reloaded and came back with the new image.
Switch 2 appears to be dead. No console out put. When power is applied, the SYST LED blinks 22 times, then stops. I've held in the mode button for up to 60 seconds, held in mode while applying power, removed the stack cables and repeated...there's not a whole lot else I can think of to do at this point.

My Vaio's screen is dead due to a dead graphic card (long/short/short beeps when starting up). But i can't easily remove the harddisks and connect them through an external USB-SATA because they are in raid 0 configuration..The laptop still works (i hear the windows 7-soundlogo) but I can't get access to it since i cannot see what i am doing for installing eg VNC or Remote Desktop software. Command line commands? try portable VNC installations? remove harddisks and bring them to a recovery centre?

Model: Linksys CM100 Cable Modem, purchased December 2010
Modem goes dead immediately after 3rd light goes solid. All lights go out and the modem stops functioning completely. Using the reset button gives no response, the modem stays dead. Upon unplugging and plugging it back in, the modem turns back on and cycles through the lights, only to die out once again.I was initially able to get it to stay alive by starting it with the Ethernet cable disconnected then plugging it in once the modem had connected, which I found odd. After a relatively short period, say 20 minutes, the modem would randomly die out again. However even that has since stopped working.

I had an old Cisco Catalyst 2948G switch that I have not used in about 7 years down in my basement. I powered it on and went through the process of clearing out the configurations, and I got to a point where one of the commands to clear out the config asked me to install jumpers for "ROM" and "ERASE". There is a third jumper labeled "NO BOOT". They are numbered J6, J7, & J8 respectivelyI found the jumpers inside and put the jumpers on them and ran the command expecting it to remove any old configurations I had on the switch and bring it back to factory state, but I was wrong.

There are green LEDs lit next to the jumpers inside, but that is all. I am not able to get any response from it on the console at all anymore.The LEDs that are lit green inside are labeled "CR5" and CR6".

My WLC running 6.0.182.0 suddenly could not accept more than 47 APs! Ihave a 1240 trying to join but failed with no obvious reason (no special errors in debugging).
I unplugged one of the joined and the first one joined!! I replugged the second one but could not join!! I unplugged the first one and replugged the second one: the second joined the controller but the first could not associate again!
