There are two access points of Cisco AIR-AP1142 (4dbi, 2.4GHz). Settle down at height of 12 meters and at distance of 36 meters from each other. Whether will cover access points a zone on the earth in between? And on what distance on the sides?

I have deployed AIR AP1142 model access points in various locations and some of them get their Radio0 going down intermittenly and the only way is to do a reload. The log just shows that the radio0 went down.

View 3 Replies View RelatedI have 2 1142 autonomous APs that I'm trying to set up for bridging. I have a building just across the street and these would work wonderfully to extend the LAN to that building for the few users that will be located there. The distance is only 200'. That's not my issue right now as I'm still in the lab trying to get these things to talk. I've been through the Cisco documentation on this and just can't seem to get them to work. Here are the requirements:
1. I'll have 2 or 3 vlans that will be used by clients
2. I'll have 1 VLAN for network management
3. I'm not using BSSIDs
4. Is it possible to utilize the 5ghz radio for bridging and still have your 2.4ghz clients be able to connect or am I required to set up bridging on both bands?
5. There's also this option for "workgroup bridging". Am I getting confused on this. I've read through it. It doesn't look like the way I need to do things.
I'm attaching the root side configuration. Version is 124-25d.JA2. The non root side is version 124-21a.JA1.
On the non root side, I get error "dot11-4-no_valid_infra_ssid: No infrastructure SSID configured. Dot11Radio1 not started.

I have a Cisco AP1142 Standalone AP at two of my locations. However both of these are being rendered useless every night and require a reeboot to correct the issue, because of the high level of noise and vibrations coming from the extremly loud bands that play there, Someone sugested an enclosure stuffed with insulation but Im afriad of overheating the AP.

The config on all APs is identical, version of IOS is the same accross all APs (12.4(23c)JA3). The only way to get reset inteface back up is to "reload". [code]
Two months ago I installed a WLC5508 with sw r7.0.116.0 and we installed 8 AP1142 as a start.
10 days the customer calls and says that the wlc logs error messages that says there is an IP-conflict with the management-interface. The conflict source is its own ip-adress!!! He reboots the WLC but the error message keeps coming. After a short while he notices that there are No APs on the WLC...!!!...
After some discussion I suggested that he should disconnect one of the two gig-ports of the WLC (LAG was enabled and in use). He did so and rebooted the WLC for good measure ... The IP-conflict disappeared but still no APs.....
In the DHCP-server (MS Win2003 server), in the AP-scope we also see that the "leased adresses" fills up with "BAD_IP_ADDRESS" (or the sort ... :-/ )
The setup is like this:
- WLC5508 running r7.0.116.0
- WLC has LAG activated and is connected to two different Cat3750G that are stacked
- The management if of the WLC is on the same subnet as the AP1142s, no other hosts on this subnet
- WLC management interface on own subnet as the only host (+ def gwy...)
- APs on their own subnet, no other hosts
- When the APs gets a IP-adress it is possible to ping them from the WLC!
- All VLANs/interfaces on the WLC is tagged, ie a "pure" trunk between WLC and 3750-stack
- Option 43 configured on the AP-scope
- All APs is connected via Power-injector (PWR-INJ4)
WLC5508 => LAG => 2x Cat3750G => TRUNK => Cat2960 with 1x AP1142 => TRUNK => Cat2960 with 6x AP1142
What we have done so far:
- Made sure the port-channel on the 3750-stack was configured: port-channel load-balance src-dest-ip
- Physically disonnected on port of the WLC
- Do "shutdown"on port gig-ports on the 3750-stack and "no shut" on only the one that is still physically connected to WLC
- Do "shutdown" on all AP-ports in the 2960-switches. Clear the lease-pool of the DHCP-server, Deactivate scope, Reactivate Scope and finally "no shut" on all AP-ports
Nothing worked, still no APs on the WLC.
I the connected my PC to the consloe of an AP that was easily accessible and powercycled it. The output can be seen below, the most peculiar was the line : " *Mar 1 00:15:53.351: %CAPWAP-3-ERRORLOG: Invalid event 38 & state 2 combination"
1. It worked initially but after the ip-address confilct and reboot of WLC no APs associate to the WLC. Why??
2. The error message on the AP console: "*Mar 1 00:15:53.351: %CAPWAP-3-ERRORLOG: Invalid event 38 & state 2 combination" What does this mean?
3. Since the AP gets an IP-address an it is possible to ping WLC -> AP, is there some freakish ogre in the Cat2960 that eats up the CAPWAP-packets??
I would like to know if it is feasible to put those Aironet AP with internet antenna like AP1142 / AP1042 in a enclosure box (Like IP66 grade) box. Will those enclosure box absorb the Radio signal from the AP? or the Radio signal can still survive after passing the box but the Signal Strength be degraded only?
View 2 Replies View RelatedI'm experimenting a strage issue with some AP1142 that prefer getting new IP from DHCP server rather than using the static ip already configured.
I've got more than a hundred of 1142 APs already conected to a 5508, all with static IP, all working fine for about a year.
As i installed 30 more AP, i enabled a dhcp scope on the controller to give IP to the new APs and when the new aps got registered i changed the configuration to static IP.
The problem comes when some of the older AP than have already static ip are gettig ip from dhcp scope.
If i look at my WCS, it reports that this APS are getting DHCP IP because they cannot reach the controller with their static ip. As this is impossible, because the static ip and the dhcp enable scope are in the same subnet in a layer 2 configuration and with the same gateway. (e.g: old AP 10.10.2.10/16; new AP(dhcp 10.10.3.10-50) 10.10.3.15/16; gw 10.10.254.1)
The problem comes when i disable the dhcp scope, all the older aps that got dchp ip from the wlc scope instead of using their staic configured ip are deregistered. If i reset every ap manually, from the swithc disabling PoE, they start to use the static ip and everything comes fine.
This is happening with about ten of fifteen APs from the 100 installed, that is the strange thing because this seem to be very random as the failing APs are installed in different building and connected to different switches.
As now i have disabled dhcp scope and all APs (old and new) have static ip everything is ok, but i will have to add some more APs shortly and every time i enable the dhcp scope on the wlc
i want to Use Cisco AP 1142 in my network. Also new to the enterprise edition AP.I have configured AP WEB mode the SSID and able to connect without the Security Key. Also want to enable MAC Address filter on the AP. Any configuration details on web and CLI Mode.

After upgrade IOS (to new Version 15.2(2)JA) without any config modification, management interface (encapsulation dot1q 33) or any IP interface with encapsulation dot1q became unreachable... If set IP on SVI (or BVI) with native VLAN (encapsulation dot1q 4094 native), this IP is reachable. Probably, there are bug in new IOS and Dot1q encapsulation? (see 'tech-support' in attached files)
