• AIR-1252 antennas required?

  Hello

  Just bought AIR-LAP-1252AG-A-KP 2, APS. I noticed that there are external antenna connectors. I have loked in the Doc, but impossible to find the info I'm looking for. I want to use inside a gym room and wondering if they will work without external antennas.

  Thank you

  Mike

  Hi Mike,.

  The 1252 has no antenna/antenna "built-in" options, so external antennas are needed;

  Antennas supported are listed in this doc;

  http://www.Cisco.com/en/us/docs/wireless/access_point/1250/installation/guide/125h_c1.html

  Take a look at this good thread which includes a good overview on the options of the antenna, Dennis, who is very knowledgeable about 11n;

• Buysing external antenna is required for AIR-AP1230A & B?

  I just went through the check tool configuration for a Cisco Aironet AP1230A-A-K9 and then for an AP1230B-A-K9. Two checked the config like OK, but had a warning on the antennas of wireless products. I hope that this means that an antenna is optional, but if I buy a dish, the only supported are those listed here:

  http://www.Cisco.com/warp/customer/779/smbiz/wireless/approvals.html

  Is that correct or is buying an external antenna for both mandatory for them to be operational?

  Thank you!

• Activate the Hotspot Peronal always requires a network reset.

  I work with a person who s iPhone 6 always requires a reset network whenever it is going to use the hotspot feature.

  1. When using this is it in a place "at a distance" - so far away they have a signal booster to the location. It is 1 bar outside of the building, so that they have an antenna and a booster. This is the only time wherever it is used.
     1. There's no wifi at the location only the cellular connection via the signal booster.
  2. The wifi hotspot feature just any lights.
  3. If he follows the procedure here: get help with Personal Hotspot iOS - Apple support, it always ends up in the network reset.
     1. It works, but in the meantime, it erases all of its network settings, as remind wifi locations.
     2. His phone is 'funky' for a day or two after that. He said that he has weird connection problems and weird problems for a period of time after that.

  It was not always so, but for about a year. He worked very well and nothing has changed at the location.

  Anyone has any ideas on what could be the cause or what else to try?

  It could be a problem with the installation of antenna and the reminder that they use. Personal Hotspot features are controlled by the carrier, and it is possible that they have difficulty to identify the device when it is connected to this reminder, and it does not identify the device as being eligible for Personal Hotspot. If the carrier supports the hotspot feature, then he is the one that allows him to be activated on the device. I suggest that they contact the carrier and fix the problem when they try to connect. I suspect it is a possible conflict between the identification of the device and the connection with this booster.

• The Pavilion Elite HPE475 need an external antenna to a wireless connection?

  I just bought this machine and have had problems with a poor quality since the wireless signal. HP technical team came up with all sorts of different explanations, and I even had to send for the "repair" because one of them think that the wireless card was defective. The last time it's because he needs an antenna.

  Can someone confirm if this machine wireless card requires an antenna to be connected to the two screws Golden at the back of the computer? What is the answer, or just another diversion?

  I was not sent an antenna with the computer, it may be a mistake the part of HP. I can connect to the internet, but usually get that two bars on the signal, while my old computer has always had five bars, as do other computers on the network. The connection keeps dropping out and is extremely slow to load at times.

  Any help would be appreciated.

  Hello

  I suggest that you take a look at what came in the box.

  The low-profile wireless network card should have with an antenna and two cables with connectors from red and blue to differentiate the connection to the wireless card.

  The service center may be assuming that you already know that... All the wireless cards that come with desktop computers have a connected external antenna with cable to the wireless card.

  This image is an example. Some cards equipped with antennas that screw directly on the gold screws. Most 802.11 b/g/n card look like this.

  Please report anything that is on the label with bar code on the back of your PC, except the serial number. The HPE475 is not a complete description of a PC.

• F20 - 132 - can I connect a wireless antenna in the antenna of my TV connector?

  Hi... I think I missunderstood something when I read the manual of my laptop... maybe someone can help me with this problem

  It is possible to connect a wireless antenna uses the same input, used for the TV antenna?

  Currently I use an adapter (supplied with my laptop) for my cable TV to work, but without this adapter I can plug an antenna wireless in there?

  This seems really strange, but that's what I heard in my manual... or the translation of the English-Portuguese was bad: P

  Can someone explain if I can plug an antenna and what type and which connector I need.

  THX in advance and sorry for my rusty English

  Hello

  The adapter is needed to connect the antenna cable, because the antenna cable supports different jack. If the wireless antenna must have the same cable as a normal antenna if cable adapter is required.
  Maybe the 3rd party Wlan antenna has an own map but I n t think so.

• Qosmio G20-102 TV TUNER: how to get this to work - what cables are required?

  Hey everybody,

  I just installed vista on my laptop QOSMIO G20-102 (PQG20), I have media library now.
  My laptop came not like MEDIA CENTER EDITION, it came under the home edition of Windows XP (laptop purchased in July 2005).
  I got 3 cables which I have no idea how to use...
  laptop was purchased in Dubai/Emirates and I live in Malta

  These are the cables >

  Hi ismael,.
  I'll try to help with that, but it's a long way to the road...
  I don't know what Tv system is used to Malta (Pal)?

  The best way to set up your TV's with Media Center 2005 edition.
  Cables:
  Check the back of your cable TV installation box and find the composite or SVHS output. If you have only the composite, you can use the composite cable of the posted image. If your TV decoder has the SVHS, so you should use, to the better image than composite. You must obtain a SVHS cable for this.
  Look for the audio output rca, too. Mix with the composite cable for the audio Qosmio.

  But you must have:
  1 control cable IR, for media center 2005 configuration as well as your TV decoder. It is cable connected to the remote sensor (see fact sheet on the back).

  2 sensor for your remote control and configure it with the remote control of your TV decoder. In this way, you can control the receiver cable channels, using the remote control for your Qosmio G20 media center edition.
  Recovery: you can change the channels on your TV decoder using the qosmio remote control.

  3. remote control for you media Center 2005, one that came with your Qosmio g20.

  Open the TV on Media Center 2005 configuration and follow all the steps required for installation.
  You must follow the guide, as is explained in the image you posted:
  http://www.Microsoft.com/windowsxp/mediacenter/using/Setup/SetTop.mspx

  If you have all these cables, you can use the Qosmio player to watch TV. It is not tied to windows OS.
  Here, simply connect the coaxial cable and let the Qosmio player search for available channels in your area. Qosmio player has the opportunity to set the colour TV system in any part of the world. all NTSC regions in all PAL regions.
  If you have the remote control for your Qosmio, TV keys will work directly with the Qosmio remote sensor on board, without needing the external sensor of Microsoft.

  I hope this helps you

• Missing antenna on the module Wi - Fi

  Hello

  I opened my notebook of 650 HP today to upgrade my 802.11ac WIRELESS and that's what I found:

  

  There is only an antenna connected to the Wi - Fi modules!

  This harm the Wi - Fi chip for standard impedance for RF components is 50 ohms, and without plugging anything power will accumulate and burn the analog frontend long-term!

  Is mine the only laptop with a missing antenna or it is a problem of production?

  See you soon,.

  Update of wifi on the laptop is a little tricky. You know that now.

  Success will be possible if you first check what's available interms of connecting antenna and impedance and band fits the desired direction to level requirements of the wifi module.

  Already, must there have supported BIOS for the desired upgrade module. See the guide HP 650 maintenance & Support for compatible modules.

  Skip a full generation of modules wifi for your laptop is not sustainable without modification and addition of wireless antennas.  You have tried from B\G\N in Acre, which is the next generation of Wifi and also happens to 5 GHz. The previous module was the 2.4 GHz band.  This will void the warranty

• Length of the cable antenna WAP200E

  Does anyone know the maximum length of the cable rg-58 50 ohm for a WAP 200 E for an antenna HGA9N? I would use a length of 50-65 ft in the air. The room of 5 ' that comes with the antenna works well, something more provides no signal to the antenna and does not seem to turn off the internal antenna.

  With the configuration of e-mail for notifications, be warned with the 5 ft length is connected and disconnected, but not with the length of 50-65. Cable was out ohm, double checked, had a talking too, etc.  Have updated the firmware on the WAP200E to 1.20 also.

  Have I run a length of cable, or do I have to climb the WAP200E and HGA9N with the length of 5 feet and run say a 50-65 ft cat 5 to the router? (wrt54g2).

  As I understand, WAP200E was designed for working outdoors. You need to mount this outdoor access point and simply run cable to your router. In this case, you can directly connect the antenna to gain high directly to the access point.

  In short, no need to 5 ' or 56 ft RG 8 cable. What you need is a 56 ft (CAT-5) ethernet cable to the access point in the network.

  Another thing you can try, you can avoid RG8 5 connecting cable and instead connect your antenna to gain high directly to the access point. This would reduce the loss of signal that will perform in a cable RG8. You can only add additional 5 ft cable CAT 5 for a total of 61 feet of CAT 5 cable to meet your requirements.

• Windows Media Center requires hardware IR with Hauppauge pvr-150

  I am configuring a Hauppauge prv-150 in Vista with a box of DirecTV, providing through the entrance Composite (or S-video) to the map.

  If I use the task/configuration option and select the TV Signal, automatically, configure Yes, Satellite, I find myself in a "select a working TV Signal".  The scan selects 1 Composite video, and I see the video signal.  But the next page says IR hardware not detected that stops the installation program.

  I have not a transmitter IR for WMC use to change channels on the Satellite box.  Is there a way to bypass this requirement or do I have to buy a transmitter IR to go beyond that?

  If there are a few problems of digital rights management preventing what I want to do, please notify and save me a lot of trouble.  I have received no indication the facility to suggest such a thing.  I saw a comment on authorized mpeg decoders, so if the pvr-150 is not allowed, I'm also wasting my time.

  If this isn't the case, is there another way to set up so I don't have the IR material.  I tried the antenna option, but it does not a composite input of my TV card.  I really didn't need WMC to be able to change the channel on my cable box.

  Saltgrass Hello,

  As a work around, you can try to plug an IR Blaster. Here are a few things to work around this problem, you can check.

  a. check whether your decoder Satellite has an IR receiver which you can connect.

  b. check whether your TV Tuner card has an IR receiver which you can connect.

  You can also use blasters IR you can connect as the IR receivers. You can use your favorite search engine and get more information on the IR blasters.

• design of huge cell MIMO 3 x 3 using splitters and antenna external omni

  Hello

  The requirements are the following:

  Offers complete coverage for a basement.

  Maximum number of users competitor is between 5-10

  VoIPoWlan

  Low bandwidth

  In the basement is distinguished from corridors and technicrooms isolated by thick walls brick and metal doors.

  In order to ensure full cogerage voip would require a large number of AP they are quire expensive and high flow is not required.

  Is it a good idea to use only a few AP with dividers and external antennas?

  For example:

  1 x dual band AP 3 x 3 mimo

  3 x dispatchers dual band, each of them has 3 output ports

  3 dual-band 3 x 3 mimo antennas 2 omni and a directional

  The basement has 2 rooms and a corridor.

  Each of the rooms has an omni antenna installed, corridor has one directional.

  Antennas are connected by separators.

  Given that the cable lengths are not the same, I may need to use amplifiers also. Is this correct?

  What about the problem of the node that is hidden, when 2 wlan stations are connected to the same access point can not hear each other?

  This cell can be huge. I gave a small example, but in our project, we need cover a basement of a square that contains many rooms and corridors. Obviously, you must use several AP + combos splitter basically repeat this small example, I gave.

  The main goal is to save money by reducing the number of AP and switches. We did the sitesurvey we found that 40-45 AP is needed. My idea is to use up to 10 AP + battery separator.

  Has anyone done a similar deployment?

  The disadvantages?

  Thank you!

  István

  MIMO radios are filled with a lot of very complex mathematics.  It phase shifts handels, changes of time, reflections, roaming, etc..  You are wanting to fundamentally change the design of their operation.

  It will be terribly.

  If it were me, I would correctly, based on the your wireless site survey, or not at all.  I don't want to be associated with a design that works badly.  I would walk first of employment.  But that's me.

  It is your reputation and your choice.

• I can't access what whether the internet associated with such sites as Web and other programs which require an internet connection.

  Original title: Weird problem.

  My computer says it is connected to the network and the network is connected to the internet, but I can't access what whether the internet associated with such sites as Web and other programs which require an internet connection. I have reset the router and the computer many times and the problem is still there. Any ideas on how to solve this problem?

  Very strange that this issue has been raised suddenly and even system restore back the working time is not solve it.  At this point, I suspect something mischievous because restoration of return must be a guaranteed fix.  If it worked on Friday, it should work if restore you backup on Friday.

  I ask you to check if your network card has got an update which could have features broke, but that can't be the problem because the restoration of return would be handed over the old version.

  Indeed, using restore in a working time essentially says that this isn't a configuration problem, because configuration is in a known-to-be-working state (because he worked at the restored time).

  I would therefore start at this stage, verification of hardware, antenna, connections, equipment devices.

• Antenna issue 1242 AP

  We seek to secure physically better our LWAP we have them now.  A plan that has been proposed is to put the AP in our closets of comm and run the coaxial cable to the locations we would like wireless signal is.  We have AIR-ANT4941 antennas coaxial standard for our ap how long of a cable can be run from the access point to the antenna until it signifigant signal loss?

  dhopper,

  If the answer to your question is not a short or easy to answer, but here's the information you need make a basis to develop a response.  Are you just planning 802. 11 b / g or 802. 11 has also? What diameter of cable you plan to use?

  Typical cable options

  LMR - 200 has a loss of .165db/ft or 1.6db by 10 ft @ 2.4 Ghz and a loss of .264db/ft or 2.6db by 10 ft to 5 Ghz more than 1 DB of loss for connections. Cable LMR-200 is approximately 1/4 "in diameter (typical antenna cable) but that the connector is approximately 1/2" (typical RP - TNC plug)

  LMR - 400 has a loss of... 066db/ft or 0.6db by 10 ft to 2.4 Ghz and a loss of .109db/ft or 1.1db by 10 ft to 5 Ghz more than 1 DB of loss for connections. LMR-400 cable is approximately 1/2 "in diameter, but the connector is approximately 3/4" (typical RP - TNC plug)

  LMR - 600 has a loss of .043db/ft or 0.4db by 10 ft @ 2.4 Ghz and a loss of .073db/ft or 0.7db by 10 ft to 5 Ghz more than 1 DB of loss for connections. Cable LMR-600 is approximately 3/4 "in diameter (typical antenna cable), but the connector is approximately 1" (typical RP - TNC plug)

  MRL - 900 has a loss of .029db/ft or 0.2dB by 10 ft @ 2.4 Ghz and a loss of .049db/ft or 0.4db by 10 ft to 5 Ghz more than 1 DB of loss for connections. Cable LMR-900 is approximately 1 "in diameter (typical antenna cable) but that the connector is approximately 1 1/2" (typical RP - TNC plug)

  So to calculate the end result here is how you do it.

  The AP transmitted Power - Connector loss - loss in the Cable + antenna Gain = radiated isotropic power (WORST) * Note: EIRP must not exceed 30 dB

  So lets run 2 scenarios with this information: 802. 11 b is power 100 MW (20 dB), power 802.11 g is 30mw (14db), 802. 11A power of 40 MW (17db) is antenna is 6db to 802. 11b / g, 5db to 802. 11A and you cable length is 20 feet.

  No scenario of cable

  802 11 b--> 20db + 6 dB = 26db = 400mw

  802.11 g--> 17db + 6 dB = 23db = 200mw

  802. 11A--> 17db + 5db = 22 dB = 150mw

  With cable LMR-200 (the numbers are close, but not exactly)

  802 11 b--> 20db - 1db - 3.2db + 6 dB = 22 dB = 150mw

  802.11 g--> 17db - 1db - 3.2db + 6 dB = 19db = 80mw

  802. 11A--> 17db - 1db - 3.2db + 5db = 18 dB = 60mw

  As you can see 20 feet of cable drastically reduced the power of access points. FCC regulations require that you stay under the 30 dB max EIRP, and for every 3db power is increased it doubles at each 3db down it is cut in half as shown below

  = 23dbm 200mW

  100MW 20dbm =

  50 MW = 17dmm

  25 MW = 14dbm

  I hope this helps to answer your questions. If you found this helpful please do not hesitate to write it down.

  Thank you

• Antenna and 1260AP issues

  Hello

  Is the AIR-ANT5135SDW-compatible with the APs 1260 R? If so, I was counting on the use of 3 antennas 2.4 ghz and 3, 5.8 ghz antennas for each access point.

  Also, can I order 1260 s as standalone APs or are they only like CAPWAPP?

  Thank you, Pat.

  As long as the corresponding connectors and frequency, you can use.

  The system configuration required

  This antenna is designed for use indoors with a Cisco Aironet 2.4 GHz radio device that uses a RP - TNC connector.

  Thank you
