• Looking for guidelines SNR for upper 802.11n (150 Mbps and 300Mbps) of data rates

  Is anyone aware of any directive of Cisco and/or observations on the ground for 20 Mhz (single channel) 150Mbps 802.11n 40 Mhz (dual channel) 300Mbps deployments and deployments?  If they vary also freq band. (2.4 or 5.0 - does not intend to make 40 Mhz to 2.4 Ghz).

  Also, if anyone is aware of any 802.11n design guidelines / planning guides (preferably Cisco) with some rough points square guidelines for generic, Interior carpet environment office (similar to the PA 1 through 10,000 feet square for the data base/light and 1 PA by 3,000 feet square for VoWLAN), but for the 802.11n which would be appreciated.

  Is enough to remind me about the need to conduct a site survey - and I realize that these figures will stretch based on the environment - looking for instructions and values of the signal, if published.

  In addition, it is understood that different customers may have different sensitivity - no need to go either

  Especially try to find some guidelines rough values published for planning purposes.

• RALink RT5390 802.11b/g/n WiFi Adapter will remain not connected

  I use a laptop of Hp 2000, and the adapter installed on the computer provided wireless is a Ralink RT5390 802.11b/g/n WiFi Adapter.  I ran the driver update tool, and it says I have install the driver update.  I have also run the tool to "Diagnose the problem", and he says that he has no problem.  However, the computer loses internet connection constantly.  I guess it has something to do with the wireless adapter, because all other wireless in the House have no problems. The operating system is Windows 7.  I'm a little tech savvy and can normally include questions to just play with it for a while, but this one has me dumb founded, and its very annoying when you try to do something and you just loose connection and have to start all over again. Help, please!

• Drivers Ralink (Mediatek (1 x 1) 802.11b/g/n and Bluetooth 4.0 Combo) is not stable on Win8

  TL; Dr. download from the support center, the Ralink (Meadiatek) drivers won't install on HP ProBook 450 G1

  Hello, recently the company I work for bought a HP ProBook 450 G1 (i5 - 4200 m, 8 GB, 750 GB, amd map with the 1 GB version) and I have to put in place. They have also bought Windows 8. So I installed windows 8 on the computer, but when I go to network, thereš adapters only bluetooth and wired connection. So I downloaded the Ralink 802.11 b/g/n Wireless LAN Adapter Driver here and when I try to install it, the installation program opens a second and then closes down, at first I thought that maybe the installation is in the background, but it wasn't the case. Then I tried to download Mediatek 802.11b/g/n (1 x 1) and drivers Bluetooth 4.0 Combo of the net here, they have installed and appear in programs and features, but the WiFi adapter is not on the menu of adapters. not it does appear in Device Manager. No driver disk is also don't come with the purchase.

  Can someone help me please? The only way to connect the PC to the internet is to use the WiFi now.

  Well this was deceptive. Everywhere where I was watching on the internet, he said that HP Probook 450 G1 has a Mediatek 802.11b/g/n card, but it turns out when I checked the BIOS it says that this laptop has an Atheros WiFi card, so I downloaded the driver on their part and now the wifi works.

• Pavilion 1009TX M6: Broadcom 4313GN 1 x 1 adapter Wi - Fi 802.11b/g/n cannot connect to Wi - Fi

  Hi all

  I have this laptop from HP Pavilion M6 1009tx. Since I bought it 3 years ago, I was faced with the question of the laptop will not connect to my WiFi automatically when I turn it on. It happens that 7 of the 10 times I would say. Sometimes it connects all rite away but above all he does not connect even if I try to connect to the available network manually.

  I then try to reboot several times as well as to try to connect to the WiFi manually, if I'm lucky it will connect, otherwise I have to keep restarting. The adapter doesnot connect even when I disable and enable (Broadcom 4313GN 1 x 1 adapter Wi - Fi 802.11b/g/n).

  In the year of punch he used to connect whenever I plugged it manually, but now I try several times for sure.

  Any help would be appreciated.

  Hi @NSIDHU ,
  
  Thank you for visiting the HP Forums! A place where you can find solutions for your problems with the help of the community!
  
  I stumbled upon your post on the laptop and wanted to help you! I looked in your question about your HP Pavilion Notebook m6-1009tx and falling wireless signal. I would change the channel on the router. Routers are able to communicate to your laptop on several different channels, and sometimes it helps.

  You could disable IPv6 for the laptop. Some say this helps. Restart the computer after trying this.

  Please let me know how it goes.

  Network power cycle:
  
  1. turn off your laptop.
  2. unplug the power to your router.
  3. disconnect the power to your modem.
  4. wait at least 45 seconds.
  5 reconnect the modem and wait for it to come back online.
  6 plug in the router and wait for it to come back online.
  7. turn on your laptop and test your connection.
  
  Reset the TCP/IP settings:
  
  1. go to your start screen/menu and type CMD.
  2. right-click on the command prompt icon and select run as administrator.
  3. in the window that opens type "netsh int ip reset resetlog.txt" without the quotes and press ENTER.

• The most effective way to log data and read simultaneously (DAQmx, PDM) high data rates

  Hello
   
  I want to acquire the data of several Modules cDAQ using several chassis to
  high data rates (100 k samples per second if possible). Let's say the measurement time is 10 minutes and we got a large number of channels (40 for example). The measured data is written to a PDM file. I guess, the memory or the HARD disk speed is the limits. For the user, there must be a possibility to view the selection of channels in a graph during the measurement.

  My question: what is the best and most effective way to save and read data at the same time?

  First of all, I use an architecture of producer-consumer and I don't want to write and display the data in the same loop. I expect two possibilities:

  [1] to use the 'DAQmx configure logging.vi' with the operation 'journal and read' to write the data to a PDM file. To display the data in a second loop, I would create a DVR samples documented and 'sent' the DVR for the second loop, where the data will be displayed in a graph (data value reference). This method has the disadvantage that the data of all channels is copied into memory. Correct me if I'm wrong.

  [2] use 'DAQmx configure logging.vi', but only with the "journal" operation to write the data to a PDM file. To view the selected data, I had read a number of samples of the TDMS file in the second loop (I'm currently writing the TDMS file). In this case, I have only one copy data from the selected channels (not), but there will be more HARD drive accesses necessary.

  What is the most effective and efficient solution in this case?

  Are there ways to connect and read data with high frequencies of sampling?

  Thank you for your help.

  You say that the measurement time is 10 minutes. If you have 40 channels and you enjoy all CHs at 100 kHz, it is quite a number of values.

  In this case, I always try to approach under the conditions of use. If a measure is only 10 minutes, I just connect all PDM data and create a graphic module that could be in the same loop of consumers where connect you the data. You can always work on the raw data files big offline afterwards, the extraction of all the information you need (have a look at the product called NI DIAdem: http://www.ni.com/diadem/)

  The main issue is that the user needs to see in the graph (or perhaps a chart can be useful too). Lets say that the graph is 1024 pixels wide. It makes no sense to show multiple data to 1024 points, Yes? Every second will produce you 100 data points k per channel. What is the useful information, which should see your username? It depends on the application. In similar cases, I usually use some kind of data reduction method: I use a moving average (Point by point Mean.VI for example) with a size of the interval of 100. This way you get 100 data points of 1000 per channel every second. If you feed your graph every second with these average values, it will be able to data points in 1024 of the store (as a default) by channel (curve), which is a little more than 10 minutes, so that the user will see the entire measurement.

  So it depends on the frequency at which you send data to the consumer. For example, collect you values 1024 by iteration of the producer and send it to the consumer. Here you can make a normal means calc or a bearing (according to your needs) and he draw a graphic. This way your chart will display only the values of the last 10 seconds...

  Once I programmed some kind of module where I use a chart and not a graph, and the user can specify the interval of the absolute timestamp that is traced. If the data size is larger than the size of the chart in pixels, the module performs an average calculation in order to reduce the number of data points. Of course, if you need to see the raw data, you can specify an interval that is small. It all depends on how you program zoom functions, etc... In my case I hade a rate of 1 Hz, so I just kept all data in RAM limiting the berries to keep 24 hours of data, so that technicians could monitor the system. In your case, given the enormous amount of data, only a file read/write approach can work, if you really need access to all of the RAW data on the fly. But I hope that the values of working capital means will be enough?

• Qualcomm, atheros AR9285 802.11b/g/n wifi adapter problem

  Hi, if I can connect to the internet, but after a bit, I'm disconnected from the network. When I have the Troubleshoot, it indicates that there is a problem with my card. It is not a problem with my network as all other devices work correctly.

  I use Windows 8; my laptop is a Pavilion dv6 - 3284ca; my wifi adapter is qualcomm, atheros AR9285 802.11b/g/n wifi adapt

  Let me know if you need more information.

  You can try a USB wireless adapter. If it works, which will restrict the cause root. If it doesn't, it will restrict the issue to a conclusion. There is not a lot of troubleshooting on the left that you don't want to, so I think that an adapter is a good idea.

• HP 14 laptop: how to replace the QCA9565 of Qualcomm Atheros 802.11b/g/n WiFi Adapter

  Hello

  I have a laptop HP 14 which is currently used for academic purposes. However, at the school, the WiFi is dual band, and so I can't connect.  At the moment I have a QCA9565 of Qualcomm Atheros 802.11b/g/n WiFi adapter and I am aware that is not double band. So is it possible to replace the current single band with a dual band adapter? Is it is possible to replace the card, then you have suggestions of what to buy and how to install the product in my book. If there is a free alternative, please keep me informed.

  Thanks in advance.

  Hey @Raiyan1 ,

• Problems of internet connectivity with Dell Inspiron 7520 (1703 of Dell Wireless 802.11b/g/n 2.4 ghz)

  Hello

  I bought a Dell Inspiron 7520 for a week now, and I had a strange problem with internet connectivity since then. First, wifi takes a lot of time to connect. After, I'm online, every 10 minutes my network access stops working completely. But if I click on the network icon in the toolbar, it starts working again, but it stops in the next 10 minutes, once again, and so on. If I try to fix connectivity problems, he always find and solve some in the network card or wireless, but then point again, after 10 minutes, or so, it happens again.

  My network card is a Wireless Dell 1703 802.11b/g/n 2.4 ghz and I tried to update and to re - download the firmware, but nothing seems to fix.

  What should I do to fix this?

  Hello friends. Recently I came across the same problem identified by many with a Dell Inspiron 15R laptop 7520 with the Dell Wireless 1703 (Atheros chipset). After losing an entire afternoon and looking at forums and their complaints, I think that I found the solution to the problem (at least, here is running).

  The laptop is connected to a router TP-Link TL-WR740N. The router is configured to run with a frequency of 20 or 40 MHz, making the switch automatically in the factory. The mobile card wireless driver is configured to work only with 20 MHz at the factory. But can be configured to work with two frequencies is adapted automatically. To do this, change the configuration (in Windows 7):

  Start > Control Panel > Device Manager > network adapters > Dell Wireless 1703 802.11b/g/n (2,4 GHz) > click the Advanced tab > select 802.11n bandwidth. Change the value of Auto 20 MHz / 40 MHz.

  Press OK and wait for to reconnect you.

  I hope this helps.
