Cisco Wireless :: 1552E Rap Locks Up
Aug 21, 2012
1552E Rap will "lock" up, and not allow MAPs to connect through it to join. the WLC. Rebooting the Rap will resolve the issue, but the problem comes back and some random point in the future. Prior to rebooting the Rap to fix the issue, the Rap shows as joined to the WLC, but I have noticed that the neighbor details look stale, meaning my MAPs don't show up as neighbors, but other MAPs in the area are in the neighbor list, listed by MAC address. At this time, I can not confirm whether or not the neighbor detials are changing (updating), but I can confirm that my MAPs never show up as neighbors.As soon as the RAP is rebooted, MAPs join the controller again.

Every time I use internet applications, browsers, game clients, games, etc. the computer will completely lock up and I am required to manually reboot it. All devices stop working and the only way to get it working again is to hard reset. I'm so fed up with it, and have tried virtually everything. On top of that, I am getting only 1-9 Mbps download speed, opposed to all my other wireless devices, which are getting 34-36, which is what my wired connection is.
Here are my specs:
Core i5 3570k
16GB DDR3 Corsair
1000w Kingwin
Zotac 4gb GTX 680
240 Sandisk Ultra SSD
z77 AsRock Extreme 4 motherboard
D-Link DWA-556 Xtreme N Wifi Card
Windows 7 Professional x64 bit
Also, When first installing the card, I used to get around 34 Mbps, as this started occurring just in the past week or so. It works fine in other computers though and my signal strength is showing 100%.

I have the following equipment
1 x AIR-WLC-2106-K9 (IOS = 6.0.199.4)
4 x AIR-LAP1131G-E-K9 (IOS = 12.4(21a)JHB1)
All configued ok with 2 SSID's associated to 2 VLANS all operates as expected.However every few 2 to 12 hours the WLC crashes, locks up.Unabale to contact via telnet or browser, will not respond to ping.The LAPs remain up but the WLANS go off air etcOnly a physical restart of the WLC will bring it back.

We purchased cisco AIR-CAP1552E-A-K9 and it has IOS c1520-k9w8-mx.124-23c.JA2. WLC with the lastest firmware 7.0.116.0 is not able to connect to the Cisco 1552E. 1552E log show that it can see the WLC but unable to connect. We have devices for both U.S and Australia domain. Why are the 1552E not able to connect to the WLC?

I am designing a wireless mesh network for a client using several 1552 access points that will be bridged together. Only the RAP has a wired connection to their existing network. The client has informed me they want to hang switches off of the MAPs to connect existing wired devices. I found this in the install manual, "To forward bridge traffic, add a switch between the power injector and controller" but I will not be using power injectors (just AC power). Will adding a switch off of the AP's impact their wireless bridging abilities?

Wireless router started randomly not allowing any wireless devices to connect to the network. A wired cable worked fine, but not wireless. So we had to unplug the router and then it would work fine.You could see the device, but not connect. We moved our wireless phone a little farther away from the router thinking it was interfering, but still no luck. It didn't matter if it was an iPod, our BluRay player, or a laptop.

my E1000 router locks up and I lose Internet connectivity until I unplug the router's power cord, wait for 10 seconds or so, then plug it back in and let it restart. This seems to be triggered (a.) when I land on a web page with intensive graphics, etc., that takes a while to load, or (b.) if I launch a web page really quickly while another one already is up. it doesn't just happen spontaneously when I'm working on the computer. This computer I'm working on is old and slow, which is why as per my earlier inquiry about having to reconfigure the router and network , I'm looking at changing to an up to date and faster model. I just updated to the latest firmware, probably a week or so ago, but the router was doing this before then and still is doing it now.

I can't find information about two features in 1524PS and 1552E/EU:
1. Does it have WEP encryption ?
2. Does it have SNMPv3 protocol for monitoring and remote managing ?
I guess, that software is similar in both, so answer will be the same in 1524PS and 1552E/EU.
How to confirm this features in 1524PS ?

My WRT54G router locks up 100% of the time when attempting to connect connect wirelessly to a Samsung Blue Player (Model number BD-P3600). I can connect to it with a cable no problem, but when I attempt to do so wirelessly and type in the password on the Blue Ray player, it attempts to connect but the router locks up and all devices connected to it (wired or wirless) lose connectivity

I'm using the E4200 in Bridge mode and it's handing out IPs from our DHCP server (not acting as it's own). I have about 8 people connecting to this wirelessly to get to our network. For some reason it locked up once every week or two and I have to unplug it (can't even remote into it).

I have a AE2500 USB Adapter. Whenever I go to connect it from my host machine to my VM I receive a Code 10 Error in Device Manager(Device Cannot Start). The VM locks up for awhile then comes to for a moment. Problem stops when the USB adapter is removed.

My e4200v2 which I have been using for about 4 months locks up or freezes regularly - as often as once or twice a week. That is to say the wired laptop can't reach the router and the smart phone does not have a signal. This often happens when there is no phone or computer running. My current firmware is 2.0.37 and it just happened again. The logging capability is absolutely terrible so you can't tell why or when it went down, and what happened just before it went down. I pull the plug on power and when it comes back the log is clean. avoid the freezing/lockup or for logging incoming and outgoing with timestamps?

Done a wifi mesh using 1552E and 1552i mix of AP's ? With the 1552E as RAP and 1552I's as MAP's ? Is it a recommended model of deployment and will it work well ? the 1552i having radiation pattern more towards the ground when mounted on top , will the mesh backhaul to the 1552E be strong enough ?
Will this work if i put the 1552e at a lower level than the 1552i so that the mesh is formed properly ?

I've looked through the documentation for loading the autonomous image on a 1552E WAP that has the lightweight image on it. All the documentation I can find mentions using the "archive" command at the command line. It doesn't appear to like the archive command.
I've seen in the documentation that it also mentions the software is loadable through the controller, but I can't figure out how to do that.
I currently have the 1552E connected to my 5508 controllers running 7.3 software. how to load this autonomous image on to the 1552E? I'm planning on using it to do site surveys with the 1552E.

Can I power the 1552e with the proper poe injector if I am not using the ethernet port for backhaul? I want to get power thru poe but use a fiber for backhaul.

In our mesh network. there are 8 root AP and 15 mesh AP . we are using 1552E ,i have few questions on it:
1. If the ap's acting as mesh ap are connected with only 2.4 ghz external antenna, will they have problem joining the root access point to form mesh.
2. How should we set the channel assignments. Do we only set them in root ap's.
3. should the channels be set under 802.11a ?
4.should the channel be manually set or should it be left to be chosen dynamically.

Is it possible to lower the power draw on the Aironet 1552e AP (AIR-CAP1552E-N-K9) so it will run on a standard PoE device (IEEE 802.3af). The spec sheet for the AP says you need to either use the Cisco PoE injector (AIR-PWRINJ1500-2=).Is there possibly a firmware upgrade/downgrade or some sort of command I can use?The APs being used are running LWAPP and require a controller.

recently I installed WLC 5508 en the central office and installed a network mesh in a remote office; central and remote office is connected with serial link as WAN, and I have dhcp server in the remote office for give ip address to all users and devices in the remote office. Additional I have 5 LAP1552 (mesh) and 2 LAP1260 in the remote office, all clients that connect to LAP1260(this don't belong to the mesh) receive ip address from dhcp server, but neither client that try to connect to the mesh (LAP1552) receive ip address from dhcp server. I don't have if I doing some thing bad. The range IP that receive the all ap's belong to the network of devices and the range ip for the users belong to network of users.

which controller I should use with 11 1552E AP ? I know 5508 will work with the AP's, but would the 2504 also work? If 2504 will work, I will go for the 2504 since its a cheaper solution.

I have a number of 1552e APs connected to a 5508 WLC. We are using local MAC filtering to enable the 1552's to connect to the WLC.
I have a several more 5508's in different locations, and can be used for back-up in the event the primary WLC fails.I have the primary WLC, a secondary WLC and a tertiary WLC loaded into each the 1552's HA tab.
My question concerns the secondary and tertiary WLCs... do I have to load all the MAC addresses in each of those as well in order for the 1552's to connect? If yes, is there an easy way to copy the local mac filtering from the primary WLC and load it into the other WLCs ?

I have a running Mesh Network with AP 1552E and Controller 5508. The end customer has a new requirement to have a indoor coverage near to AP1552E (mesh AP). But in this building he has not any wired Network (it is far from any switched site). The question is: We can use an AP1262 indoor with Line Of Sigth to AP1552E in the running Mesh Network? I know AP1262 can be used in a Mesh Netwok (Root or Mesh) configuring it as BRIDGE [URL]

What is the power rating of a 1552e mesh AP before the antennas are attached? I have the dual band 2.4 / 5 GHz antennas. I know their Db rating, but I have not been able to find what the AP is.

I have to build a MESH topology with 1 Root Access Point and 4 Mesh Access Points which are 1552E.I have a wireless controller which is a WiSM 2 card into a 6500 chassis.I want to know if there is a pre-configuration to do on the AP before installing it, or if they are automaticaly discovered by controller (even for MESH AP which are NOT wired to LAN) ?

We have a number of 1552e's deployed as RAP / MAPs, using a 5508 WLC. All those are working fine.I have a few requirements for an outdoor access point... not a RAP or MAP, but just a simple outdoor AP. I assume that if I use a 1552e for that requirement, I would place the mode in local, rather than in bridge mode, correct ? Also, a question on mac filtering. When setting up the mac filter, there is a drop down selection for "interface name". The radios seem to work fine with "none" selected, so I'm confused about what exactly that selection is doing. Is it simply a reference lable, or does it actually have a purpose?

i have a problem with 1552E to register with 5508 WLC, and always got "AAA authentication error” in the WLC log, while AAA is not enabled. so my question is , do i need to add the MAC address to the WLC MAC filter list even if i not enable the AAA server in the WLC.

A 1552E has a temperature gauge sensor connected to its power over Ethernet port. the port status shows line protocol as down.The cable from 1552 to the sensor has been changed twice. We can see the 1552E gig1 interface is at 1000full duplex. Is there any chance the speed is causing the problem here. it seems the 1552E doesn't allow to set different speed & remains on 1000.
