Cisco Wireless :: Maximum Possible Transmitting Power In 1242AG-E-K9
Feb 28, 2013
My question is about the maximum possible transmitting power in a Cisco 1242AG-E-K9.I did an update of my AP on a new ios version and since then, the maximum power for me is limited to 17 dbm. I check this within the console and the "show controllers dot11radio0 | include Power:" command. I thought that I had 20dbm before the update, but unfortunately I can't proof this by myself because I have no AP left with the old firmware.
Is it possible that the upgrade did this? I read about the regulatory domains for the transmitting power. I live in Switzerland, so I thought I could use 100mW if I want to. I read it's not possible to use the 100mW at each speed but I think I should stull be able to select the 20dbm/100mW or am I missing something?
I have a very special application where I need to connect as much as possible end devices to a single access point.The required data throughput per end device is very small - around 1 to 5 kbit/sec.I am using the Access Point Aironet 1242AG.
Questions :
1. What is the maximum number of simultaneous users that can be connected to a Cisco Access point, is it 255 or can be more ?
2. If I define multiple SSID’s, what if the total numbers of users that can be connected to a Cisco Access point
3. I there a simulator tool that can be used to simulate multiple wireless connections to an AP
4. Have anyone tested so many users connected to 1 Access point ?
I'm having a little issue with some Cisco Aironet1242ag WAP's. I receive a call at least twice a month stating that some of the WAP's are not giving out internet connection. What I always do is go to my patch panel and disconnect those WAP's not working and connect them back again so they can power cycle. These WAP's are connected to a Cisco3750g. Once the WAP's boot up, the users can connect to the WAP and connect to the internet.
I don't know if these WAP's are filling up with some information that causes the access points to not connect to the WAN.
I will be doing a site survey using the client's Cisco 1262 with only 1 radio (g/n), 3 antennas. What is the maximum transmit power, 20dBm or 23dBm? I need to set the transmit power in the Airmagnet to 50% or 3dBm down as recommended by Cisco.
I am looking for the Maximum Power Settings Spec for the 3600 AP. The one from 2008 is too old. Does an update exist? The AP Spec itself does not show power levels by channel and regulatory domain which is what I need. If I can't get the spec, I will have to query the AP using "show ap config 802.11x apname" for each config I need.
I have a deployment of AIR-CAP35021 APs. They are in 2 buildings with multiple floors. They are installed in a row down the hallways. I want to increase the power levels by using the controller and not configuring the APs individually. I have set the TPC value to -50 but I still do not reach the outer walls of the floors in some areas. I need to know what to set the Max Power Level Assignment or Min Power Level Assignment to to get the APs to power up some more. If the MAX value is 30 and the default is 30 then how to adjust that value?
I am relocating UPS units and will need to buy longer power cables to extend from our 4506 and 4510 to the new location.I think I am looking at 15 to 20 feet but I am going to confirm. Is it okay to use longer cables?
I am trying find out what the nominal power draw is for the following switch. The installation manual and data sheets says that the power draw for the units are 15.1W and 15.7W maximum at 18VDC. I am trying to use the switch for a solar application (12VDC) and would like to find out what the nominal draw would be when the device is in standby or if all of the ethernet ports are unused. I plan to use the two fiber SFP's and one copper port.
I purchased a EA4500 and at first I could connect to it through its default ciscoxxxxx ssid on my laptop which is 2.4GHz only. I upgraded the firmware using the PC utility and now I can't find the 2.4GHz SSID no matter what settings I do. I've disabled and enabled it multiple times, changed it to have no security or with security and enabled and disabled it and renabled it. Nothing seems to work, but for some reason the 5GHz side I can connect to using a 5GHz device. I've also tried disabling the 5GHz side, but still no 2.4GHz.
I'm having an issue with a 2 week old WMP54G pci adapter. The behavior is as follows: I get a successful connection and excellent speeds, but every 10 seconds it stops transmitting and drops off the network for a moment. Then everything comes right back. 10 seconds on, drop, 10 seconds on, drop.I've investigated possible sources of interference, but there aren't any strong networks coming though on the same or nearby channels. Moreover, other devices sitting in essentially the same spot are connected consistently and show no variation in the signal strength.
Other info: OS is Ubuntu 10.10, the machine is a Dell GX270.
I am facing a problem with transmitting of VoIP traffic through VPN.
I have a 1921 router in my end where two ISP's terminate and load balancing is done over the ISP'S. I also have a site-to-site IPSEC VPN connection to remote location. Also I am having to analog phones connected to the network through an ATA. My Call manager is in the peer end and has public IP assigned to it. The IP phones get registered when coonected to general inernet connection.
The loadbalancing and VPN is working fine. Now I need to transmit the VoIP traffic over the VPN. I have configured the same but seems not working. [code]
My current network has a Cisco WLC 4440 with a number of Aironets connected. I noticed that it says there are about 90% of my APs are rogues. closer investigation in the Rogue APs page shows SSIDs of a few businesses around. When i click on the mac address i see that the rogue is not on the wire but i have a number of APs dectecting each rogue.
Now the question is are my waps transmitting or repeating these rogues? If so how can i prevent it without sending a deauth to their wap which is not part of the good neighbour policy ( as i understand it)?
Not sure if this is part of the same question above too, but i do have a rogue client on an SSID that is not mine but shows up on my AP, what is legally right for me to do to prevent use of my network devices by the external client?
The switch has been set to Level 3 Routing. Port 27 has been in use as a Fiber Transceiver with no problems for several weeks. This week I tried connecting a second Fiber Transceiver to Port 28, and it would not work.
Swapped the physical GBIC modules in the ports, and the situation remained exactly the same: Port 27 works, Port 28 would not work.
Connected to the copper-part of the combo Port 28, it immediately connected and worked fine.
Connected an external Fiber Transceiver Box in place of the GBIC in Port 28, and it immediately connected and worked fine.
Swapped the new Fiber jumper (Port 28) with the existing Fiber jumper (Port 27), and the new connection came up immediately and worked fine. The existing connection would not work when connected to Port 28.
By "not working", I am not able to ping across the connection. The link light comes on and blinks. The transmit/receive statistics show as if data is processing on this switch, but on the other side of the Port 28 connection, the switch shows Transmit traffic, but no Recieve traffic.
My internet connection is continuously transmitting and receiving, even when there is no application running! is there any way to find out what is being transmitted or received and how to reset the connection?
On our conference floor, AP 1242AG already exist but I am going to add AP 3602i to increase wireless coverage. . Any issue or concern with this type of setting?
is this possible, i need to convert a 1242AG Autonomous back and forth this weekend to use for a quick project for testing. i need to do: take the AP into LWAPP mode (i know how to do this with the aironet utility) take the ap from LWAPP back into a AP mode so i can use it as my access point again. [code]
I need to bridge from our office to our shop that is around 800 feet away. Here are the Details
I need the 2.4 ghz antenna for client access (Iphones are not compatiable with 802.11a) The locations are 800 feet away but are line of sight. I need to use the 5ghz antenna for the bridge i have 2 aironet 1242ag's I have 2 2.4 ghz AIR-ANT3213 antennas (planned for client access) I have 2 2.4 ghz AIR-ANT2506 (maybe useless for this)
My problem is that the range of all the listed 5 ghz antennas. None that i can find will bridge 54mb over the 5ghz radio for greater than 170ft
The closest that i can find is AIR-ANT5195. If i put these on both sides and it is outdoors line of sight, will the best i can hope for is functioning and 6mb
I am in the process of moving our office and part of the task involves relocating our existing wireless access points. They are all 1242AG's running the c1240-k9w7-mx.124-10b.JDA3 IOS. I would like to change the security on the access points to WPA 2 but that selection is not available. I think upgrading the IOS will solve this problem but I am not sure. So I guess I have two questions:
1) Does this Cisco model support WPA 2 ? 2) If so what IOS do I need to load to make WPA 2 available?
I need a temporary additional broadband connection at home and I was thinking about a bt openzone hotspot connection... I have a cisco 1242AG access point which can do bridge mode. The BT openzone thing requires a username and password. Is it possible to connect the 1242 in bridge mode to bt openzone?
What would be the ramnifactions of using AIR-1242AG-A-K9 (g radios only: no b clients) and AIR-LAP1231G-AK9 (g radios: only no b clients) with AIR- ANT1728 (non diversity antennas) on the WLAN. Some of the APs 1242/ 1231 will be with in line of site of each other.
I have an issue with a loss of connectivity after 10-15 seconds. I have a Cisco WLC 2504 controlling a Cisco 1242AG AP. The following is the topology.
Wireless Client -> 1242AG (AP) -> Port 3 WLC 2504 -> Port 1 WLC 2504 goes to fa0/2 on 3560. Port fa0/1 goes to ASA5505 (Inside)
All devices are on VLAN 10 10.50.1.0/24. AP is getting DHCP just fine and is associating with the WLC just fine. I connect my laptop to it and it connects just fine.
I then ping the gateway (ASA) 10.50.1.1 or the layer 3 interface on the switch 10.50.1.7 and it is fine for about 10 seconds, then it just dies then comes back in a few minutes and then goes away again. I have looked for duplicate IP's and can find none in any arp table.
It I just ping the controller 10.50.1.20 it is completely stable. I have moved the WLC directly off the ASA5505, moved the switch port, changed cables and the problem follows. I have even moved the AP to be directly off the switch instead of the WLC and the problem still occurs.
I have an existing 1242AG AP in a remote location, I have full access to it. I have a new 1242AG that was ordered but the client forgot to order antennas for it. Is there a way I can find out the exact model of antennas that are connected to the in place AP at the remote location??
How can I configure the wireless not to be shown for users,but used by them? On a Cisco 1242AG I mean when someone do a wireless discovery not see my wireless name, but typing the name be able to connect it.
I have an AIR-LAP1242AG-A-K9, serial number FTX1623B0RX. I just need to know how old this unit is. (I haven't attached it to our Cisco account, so I can't open a TAC for it.)
Boot Version 12.4.13.0 IOS Version 12.4(23c)JA5Mini IOS Version 3.0.51.0
I have 2 1242AG APs setup with one SSID and no vlans configured. The APs are connected to a switch along with my DHCP server. Clients are able to connect to the SSID but are unable to get an IP from the server. Clients can plug into the switch and get an IP. If I configure a static IP on the wireless card, the client works fine.
Is there something I'm missing on the AP to allow DHCP requests to pass through? IPhelper?
Here is the AP info: AIR-AP1242AG-A-K9 12.4(21a)JA1
I keep getting alerts from our WCS stating that our 1252s are drawing low power. Now I am aware that they require enhanced PoE (up to 20W) but as we only have standard PoE in that building we purchased the 1252 series power injectors to go with them.
However, even with the correct power injectors the WCS still reports the draws low power error.
Is this a bug? Running WCS 7.0.172 at the moment.
Forgot to say we are using the PWR-INJ4 and the injector status is enabled and you see the injector MAC address when you drill in to the AP status.
I'm using a wlan controller with 1242ag converted to lwapp, i'm trying to enable 5.8 but when i change the from local to bridge the lwapp disappear from controller. May be that the firmware does not support mesh !I'm following the 4402 wlan manual at page 641.
