• Power of the weak signal with my wrt54g

  My wireless router has been uneven, since my cable company installed a new internet cable modem.  I powercycled several times, downloaded the new firmware, rebooted and still have problems.  Lately when I finally get on the internet with a wireless device, the signal is very weak.  It is low on my iphone on my Mac laptop and also on my Samsung Bluray player.  Lately a window never ceases to appear when I'm watching netflix who says my bandwidth is too low, even if he works very well for 2 months.  Is my router obsolete?

  No, it is recommended to have security enabled. Does affect your signal strength when you activated? If this is not the case, go ahead and re - activate.

• Equium A300D - power of the weak signal on built in wireless

  I've had my Toshiba Equium A300D - 13 X for a few years now. I also have sky ADSL broadband for a few years. My signal from the router (netgear) until a couple of months has been very well. The router is located in my hall, and I use my laptop mostly in the lounge which is through a wall, 3 or 4 meters. Strength showing on the wireless icon in the tool bar used at least 4 or 5 bars but now the best I have is 3 bars force and my connection is variable with Web pages take longer to load.

  If anyone has experienced this? Could there be something wrong with the internal wireless antenna?

  Any advice would be great.

  Hello

  Have you changed anything on your phone (settings, updates), router (update firmware, settings), or perhaps in the region (placed a device which can interfere with the signal)?

  We have about forty points of access Cisco Aironet 1131AG spread over four floors and they all have a static IP (BVI1) on the same SSID, customers will be on its own virtual local area network (dhcp on 3750 switch) and they use several channels (1,6,11).  Cisco Wireless Control System is pending. This wireless network should support roaming for customers (there will be Wi - Fi tags of multiple AeroScout and wireless laptops). To measure the strength of the wireless signal and wireless coverage on each floor. My questions are:

  1. How to measure the strength of the wireless signal: we must meet at least three APs available with signal excellent (I guess for the WCS needs that will determine the position of the client in the building)? We thought to use NetStumbler and a few laptops with wifi and measure as many points as we can as simpler thing. Or should we use something like Cisco Aironet Client adapters for our mobile phone and then use Cisco Aironet Client Utility (is it worth buying for our analysis and measurement)? Any other idea?
  2. What signal level should we consider for a good wireless (dBm)?
  3. That we should propose for authentication, authorization and management accounting? What happens to the roaming wireless? I did not quiteunderstand WCS, WDS and WLC-that should be used for above tasks?

  Thanks in advance.

  "Use the command on the AP" sh dot11 associations "will give you the clients associated with success.  If you add the MAC address of the client at the end of the command, you will get detailed information.  Look under "Signal Strength" and "Signal to noise".  Under the strength of the Signal, you want a value of-75 dBm or lower (lower values the better).  -76 dBm and is bad.  Under Signal-noise, you want a value of 25 dBm or more (values higher the better).

  To measure the strength of the signal, I use Airmagnet, but you can use Netstumbler or Cisco Wireless Site Survey.

• Point of access Cisco Aironet 1200 series help

  We have 4 Cisco Aironet 1200 Access Points and they are all set to authenticate with our RADIUS server. However, authentication is hooked and can't understand why. Does anyone have any knowledge/experience with Cisco Aironet 1200 Access Points configuration?

  OK, I do not work with the GUI so although the memory is a little hazy but from the APs home page look on the left hand side and there is an option for something like "Software Setup" or something to that effect. You should be able to find the IOS version of here. This requires that you are indeed runnig IOS code. How old are these APs? If more than a few years ago (and perhaps even more recent) that they could very well be running VxWorks and then we are in a different ball game. If you see what I have described above and the homepage for the AP is often white with a bit of greenish-blue, bluish-green color then IOS, if it is more colorful, yellow stuff and VxWOrks.

  I hope this helps. Let me know if you need anything that anyone else. I will try to answer as soon as POSSIBLE.

• Cisco 1200 Series AP - expand the network?

  Hello

  I have a Cisco AP's 1200 and there are 2 rooms in my house where I do not have enough reception.

  Can I use something like a Repeater or a bridge? I have active encryption LEAP.

  Thanks for your help,

  Concerning

  Bottom

  Not exactly - the second access point in your case would be configured as a Repeater, so nothing would be connected to it except the power cord. It is tuned for the AP main reason for which the flow of this AP will be half of the regular AP among other things.

  What I would do if I were you (because I don't like repeaters) is buy a linksys router and plug the modem cable on it.

  This does two things - you have now the possibility to create a network internal behind this 'physical firewall' using the NAT translation. You have also 4 ports that you can plug stuff in to share a connection.

  So, you plug the two AP in the linksys box and now you have two RF cells that provide flow high with out having to repeat.

  The drawback here is to get a cable to the furthest AP.

  The result is the AP do not have to be next to the cable box and you can now location in more desirable places around your home to maximize coverage without sacraficing flow.

  The added benefit to protect your data from queries ping not allowed and do'ers wrong trying to pop locks easy.

  see the "shields up" pages on www.grc.com who will explain better than I probably...

• The weak signal filtering

  I filter a signal of amplitude of the 0.2 Volt connection. It consists of pickup and noise of the line. How to do? Is the software filters are enough or I have to design a filter material?

  Hi sukhiray,

  If you have less than the full version of LabVIEW, there are several software filtering options available in the category of Signal Processing. You can configure your thresholds and the order of the filters and choose between the different types of filter. The choice between hardware and software depends on your needs and signal.

• Weather a barrier on the power of the wireless signal?

  FREE WI - FI, RAIN & SNOW

  If a Protocol "N" dual-band WI - FI adapter which is connected directly to the USB port of a laptop computer inside the House and the router is in the garage about ten feet, should there be a weakening of the reception quality in the good House when it happens to be raining or snowing in the area of 10 feet between the garage and the House?  In other words, in addition to METAL interference or microwave OVENS or WIRELESS PHONES... not the weather elements possibly hinder these network connections?

  I thank very you much for any information.

  Joe

   

  Hello

  The weather could affect the signal strength. Radio transmission uses digital spread spectrum. Even if a small problem can spend because of lightning nearby, the packet will be retransmitted, you won't notice a difference. (Unless the lightning blew your 2.4 GHz wireless system telephone and microwave ovens are generating more effective disruption.

• The full signal on WRT120N

  Hi all, I am new to this community, but I am using Cisco products for years.

  I have install my router by myself, I'm not a newbie, but tonight I did a restore to factory default on my router because I found a few problems of slowness on internet (very slow). Now it works well, BUT...

  I would like to know if it is possible to activate the power of the full signal on WRT120N as maximum as possible.

  -

  WRT120N [Wireless-N Home router]

  Firmware version: v1.0.05

  -

  Current settings:

  Mode: joint

  The network name (SSID): D

  Channel width: 20 MHz only

  Channel of the scale: n/a

  Standard channel: 6

  Security: WPA2 Personal

  SSID Broadcast: enabled

  Try to change the standard channel on the router and see if it makes a difference in the power of the wireless signal.

• Cross spectral power and consistency of the 2 signals

  Hello

  I try to get the cross-spectral power and consistency of the two signals. I should be able to get this:

  "The cross-spectral power and consistency of these 2 signals have been calculated on a window (8.5 minutes) 1024-sample using the fast Fourier transform applied to the 3 overlapping of the panes of 512-sample in the window of 1024 consistency." In each pane, the data were the first linear straightened and with windows by using the Hanning (cosine) function before the calculation of the Fourier transform. The 1024 coherence window was so advanced by 256 samples (2.1 minutes), and the calculation repeated until all BDUS/interval of N - N series have been analyzed.

  We used the product of consistency and the cross-spectral energy to weight these 2 effects in order to quantify the degree of the hitch.

  I should get this chart type

  

  The RR signal I straightened before that trying to get the power crossed with sampling freq = 2. And I put 2 ways to get it.

  consistency too and later the product of the two. Im trying to get the spectrogram and watch later 3d like picture.

  I have attached the vi.

  Consistency is perhaps badly fixed.

  Thanks for the help, guys.

  Kind regards.

  you made a few mistakes, example en by overhauling it you can't do the segments overlap, that's why you should go with a loop and the creation of a subset (and this is why I suggested para window ASD)

  You must also set the indexing of the product release and do not concatenate, penny you released 2d end that you can use for 3d graphics

  FS in the mathscipt should also be in hz, not in seconds, I told you the last time (he is shown in the help)
