• How to reduce the use of bandwidth LAN?

  I want to design a relay system using two USRP of NI USRP 2922 with sample rates even as LTE standard. But there is limitation in the use of bandwidth of 1 Gbps LAN.

  I don't think you should achieve the full rate on a USRP without a link dedicated to the PC.  The protocol used is UDP between USPR and PC which can be disruped by the latency of the network and cause packets to arrive out of order or get lost.  You should also assume that, due to the effects of edge filter only 80% of the specified bandwidth is usable.  (20 MHz of bandwdith requires a rate of IQ of 25. MECH / s)  It takes a fast PC with a very high quality (we use intel) NIC to get there.  But you will need to use the driver for the NIC card manufactuer and maximize the RX and TX buffers.  So far, I realized only on desktop computers and mobile no.  I also would assume the package of 20% load, so on a 1 Gbps link, I would not expect to exceed the 800 MB/s.

  25 MS/s x (16 bit 16 bit I + q) = 800 MB/s

  You can also, in the pilot, 8-bit mode which will halve your dynamic range, but also the data rate.

  For a system like yours, you can consider to put a PC next to each usrp and install 2 network cards in each PC.  You will add the latency, but the additional computer will give you buffer against congestion and network problems.  In addition, relay is not a 'constant' streaming activity... only the RX is constant.  For TX, you can use the approach of gusts of transmission.

• How to increase my use of the network

  I'm trying to download data from a remote computer using the SSH client.  My problem is that there are several data files, with some more than 5 GB and my use of the network seems to be only 1% when I followed my network connection using resource monitor.  I wish I could increase my use of the network to 100% for a temporary period.  I was able to increase this value to 5% by increasing my virtual memory 151939 MB. Is there something else I can do?

  Here's an option to try: http://www.mydigitallife.info/2007/05/24/increase-multithread-download-speed-by-disable-vista-auto-tuning-on-tcpip/.

  You're confusing several similar-sounding terms. The use of the network that shows on the Task Manager is on your local network. and will show as a percentage of the speed of the LAN (usually 100M), this bandwidth is available for traffic between PC on your LAN.

  Your download speed is usually limited by the speed of your connection to your Internet access provider. If you run a speed http://www.speedtest.net/ test (ignore all the ads and just run the speed test) and you will see 56 Kbps or if you see 437 Kbps which seems low for a broadband connection, then there may be a problem with your internet connection (but it can also display as perfectly well and maybe even better than average).  If your test shows below average speeds (I mean well below average - not just a little bit):

  (1) try a test of speed of a wired connection. If this test ok, the problem is the wireless from your pc to the router.

  (2) if the wired connection is slow and you run DSL, check that every phone in your House has a filter on the plug and the dsl modem has a separator.

  (3) call your ISP

  I hope this helps.

  Good luck!

• iOS 10.0.1 "not allowed to use the restricted network port.

  I just upgraded my iPad Mini iOS 10.0.1. He is now running Safari 10. I tried to visit an internal/private IP on port 4190 using HTTP. I get an error that says:

  Safari cannot open the page.

  The error was: "not allowed to use the restricted network port.

  On iOS 9.3 using Safari 9, the same URL opens fine without this error.

  Do not know what has changed since iOS to iOS 10.0.1, 9.3 but I'm unable to visit a web site that I have visited before.

  I know that WebKit maintains a list of ports that you cannot go (e.g. 6666), 4190 is not a restricted port AFAIK. I don't know why I get this error message.

  It seems I was looking at the wrong source code.

  I finally got a clue where to look after visiting the page Web Safari Technology Preview 13.

• bandwidth network and iTunes

  I use Little Snitch Network Monitor on my iMac. Earlier today, I noticed that the monitor showed a constant flow of data going down. When I looked, he showed that iTunes had 37 connections to the server and that was a total traffic of 55MO upward and 11.4 Go down into the last day and a half. I work from home so I tend to leave iTunes running all the time even if I do not use it. I turned off sharing at home and stop sharing my library on my local network only on the possibility that something was hammering. It made no difference. Network traffic drops only when I closed iTunes. As soon as I stopped him, the descending stream stops. I'm on fiber, so I'm not really worried about my use of the data, but if I let on, we are talking about about 150 GB of data in a month when not in use. The only thing that has changed is the recent update of iTunes. I'm not in the beta or GM of Sierra. I'm always on the latest version of El Capitan.

  Someone has seen this, or has any idea of what could be the cause I have?

  It had to be something Apple like this on the back-end. He passed for another day and then stopped.

• Satellite Pro A200: Recovery using a ghost network boot disk

  Hi all

  Need to ghost several satellite pro a200 machines using a ghost network boot disk. When I use disk ghost provided by the ghost boot Wizard and no boot on PC back I get the message 'No Fast Ethernet PCI Adapter Found!' Serious internal error! (hardware works fine under XP/Vista)

  I tried to boot from CD, Mem Stick and USB floppy with the drivers of toshiba and realtek without success, research on google seem to point to there needing to be a driver to interface with the cardbus / PCMCIA adapter - if it IS the case can anyone shed light on the fate of a pilot and how I could continue on this?

  Thank you very much

• N300 wireless Extender - using the Extender Network and the primary network

  Is it possible to use the wireless N300 extender only in areas where it is needed and the main network elsewhere?

  I want to be able to use to boost the signal to a smart TV via an ethernet cable, but want to use my main network in the rest of the House where I can get faster speeds.

  At the moment he seems to want to connect to all devices in the House.

  Hello elies

  If you your extensor different SSID name of your primary network, you can decided which devices connect to the Extender and those which connect to the main network.

• Using Zyxel wireless network configuration

  Using Panel to have Windows configure my system to use a wireless connection to internet via Zyxel USB. Using Windows options, network, Network Setup and configuration of wireless network connection me don't upset none the case. I understand there is a way that Windows will automatically connect. I need to update my Windows? I would like assistance. Bill

  Thanks for the information.

  No, you don't need an update.

  I do not understand your answer to no. 5, in particular "the material was not recognized by Windows, it requires a manual boot without Windows manages the connection of the device to the router."

  In Windows, there are basically two ways that a wireless adapter can be controlled.  Windows can control the unit by using a feature called 'Wireless Zero Configuration' or a utility provided by the manufacturer of the card.  As a general rule, you want one or the other - not both active at the same time.

  If the icon you are referencing is a 'Z' in a box (http://tinyurl.com/cjn3mje), then the Zyxel utility is in charge.   Which is perfectly OK (and probably provides more features than Windows WZC), but I'm not familiar with the details of using the Zyxel utility.  If you identify the model of your adapter, I can see if I can find his online user manual, and explain the steps you need to take

  If you use the Zyxel or Windows WZC utility, you must take the basic steps are the same:

  1. search for available wireless networks.
  2. identify your network in the list that is displayed (this is your SSID or 'Network name')
  3. click on "sign in".
  4. Enter the encryption password when you are prompted.

  Did you do the above?  That's happened?

  Additional information:

  Windows WZC automatically saves the connection (SSID and password) information once you connect successfully.  I don't know if the Zyxel utility done automatically or if you explicitly save a 'profile' with the data.

  Any utility that you use, you must know the SSID of your router and the password for the encryption.  Verizon technology that installed your router should provide you with this information.  It can also be written on a label on the bottom of the router.

  If you do not have - or lost - this information, you can find it by connecting to the router.  Preferably, you should do this using an Ethernet cable - assuming you can get your computer back close enough to the router.  You will need to know the name of user and password to connect to the router.  Again, Verizon technology would have to provide this information for you.

  As far as I can determine '20.10.7' is the revision number of the firmware of your router.  I believe - but am not sure - that the user guide is here--> http://www.actiontec.com/support/doc_files/MI424WR_Rev._E&F_User_Manual_20.10.7_v1_GPL.pdf

• How to check who is using my wireless network?

  I just want to be sure that no one is using my wireless network... I know I did a password to get access to it, but is their way to check if its working?

  In addition, when I went under network settings

  I found something that is called gateway residential... don't remember really see it, but when I go in there, it shows something called teredo... and it has an IP different than my router... no idea what it could be?

  Disabling Wireless SSID Broadcast will arrange this?  making it not visible by anyone but me?

  If you are using WPA or WPA2 and a strong password, nobody is your wireless network, except you.  Anyone who has the skills, computer power supply, time and determination to break into such a system is busy breaking in banks, not your home router.   Then don't worry about this.

  You can check that your router is using WPA or WPA2 and your password by:

  (1) connecting your router 192.168.1.1 and ranging in the wireless section and check that the WPA or WPA2 encryption is turned on and that your password is entered.

  (2) you can check that the router is working by connecting wireless using the password.

  (3) you can check that you have connected to your router first getting a wireless Internet connect, then unplug your router and check that the Internet suddenly not working.

  "teredo tunneling" is a way to move to IPv6 info from an IPv4 router.  Don't worry about this.

  Do not "SSID Broadcast" set to 'off '.  With modern methods of piracy, that old thing of security is now worthless.  Furthermore many wireless adapters have problems connecting to routers that broadcast their SSID not, so it might cause you problems of network.   If you are using WPA or WPA2 and a strong password, who cares if someone sees your SSID?   Without your password, they cannot connect wirelessly to your router.

  I mean, strong password, at least 24 characters random, including uppercase, lowercase and numbers.  Although I recommend 24, or 12 is almost impossible to crack.

• Can I connect my HP4625 all in one directly on my ipad/iphone without using a wifi network. ?

  Can I connect my HP4625 all in one directly on my ipad/iphone without using a wifi network. ?

  Hi xxtopgunxx,

  Welcome to the HP Support forums.  I understand you want to print from your devices Apple to your printer Deskjet Ink Advantage 4625 without the printer is connected to a wireless network.

  It is possible that we can get the printer to disseminate its own network. Please note that the network will broadcast the printer will not have access to the internet.  Please follow the steps below:

  • On the front panel of the printer, please press the wireless button
  • By using the buttons on the right, highlight and select wireless settings
  • Highlight and select Restore Defaults
  • Select Yes. A message appears indicating that the default values of the network have been restored
  • Open your application settings on your Apple device, please
  • Please click on wifi and choose the network that starts with "HP-SETUP.  This should connect to your Apple device to the printer
  • Now you should be able to print using the 'Action' icon.  If there is not a print option when you press the action icon following all guidelines for Apple AirPrint

  If you go to print and your Apple device does not see the network, you will need to follow the procedure again. It should be at least 60 minutes before the HP - Setup network ceased broadcasting.

• Problems connecting to the internet using the wireless network connection

  I can't connect to the internet using my wireless network connection. I had made the diagnosis and he stated that "the DHCP is not enabled for the wireless network connection. I had checked the DHCP, but it has been activated!... Someone would give any suggestion for me to solve the problem?

  Open the run command box by pressing Windows key + R, type services.msc and press enter . Search The Client DHCP and check if it is enabled or disabled. If disabled then turn it on and see if the problem still persists or not.

  Open the run command box by pressing Windows key + R, type cmd , and press enter . At the command prompt, type ipconfig/all and press ENTER. Now, check the IP address, default gateway, DNS etc. If you find all the information is correct, but you cannot yet access the Internet so if you connect the wireless network is secure or not. To determine the glance to the wireless network icon in the taskbar, then click on it. It will show you the available wireless networks. If there is a "yellow shield" present on the network icon, the network is not guaranteed, if there is no "yellow shield" does while the network is secure. In a secure network, you might have a "network security key. In this case try to disable the 'Network security key' option for this network. To do this:

  Open Control Panel , click network and Internet , click network and sharing Center , click manage wireless networks on the left.

  In the list select the wireless network and do a right click, select Properties, Security disable tab all options that is, in security type do not select no authentication (Open) and to the type of encryption , select none . You can also activate the automatic connection and SSID settings to further enhance connectivity, on the connection tab, click to select the "connect automatically if this network is in range " and "check boxesto connect even if the network is broadcasting his name (SSID) .

  For more information click here and see how you can determine whether a network is secure or not.

  http://Windows.Microsoft.com/en-us/Windows7/how-do-I-know-if-a-wireless-network-is-secure

  If the problem still persists, then check your firewall settings and make sure that the firewall is not blocking your Internet connection. Some software Antivirus has a built-in firewall and they block by default all unknown connection to the tightening of security.

  Try to restore Windows Firewall default settings. Open Control Panel click on network and Internet , click system and security , click Windows Firewall , click default settings .

  Hope this will help. Thank you.

• Problems with the WEB BROWSER blackBerry Smartphones, use not wifi network to open some Web sites

  Hello I'm owner of BB BOLD 9900 OS 7.1... for the last two days I am facing a pretty annoying problem with the BB browser.

  It means not affects the device... it just annoys me.

  When I TURN ON my WiFi on my BB with the network carrier Sim already homepage active who has a Active on it and open the web browser BB, according to the website on which I open the web browser chooses between the internet Wi - fi OR internet BIS carrier which is weird. BECAUSE a default if the wifi is enabled, then the web browser MUST use internet wifi network carrier for navigation. YOU TUBE, FB and TWITTER.com all use my carrier netwrok to open bt soon I open BBC.com or CNN or any other site the wifi symbol appears on the right side and so it uses the wifi network... and disappears when I opened THE 3 SITES you tube FB n twitter.

  My knowledge is that when you activate THE wifi network, the WEB browser is intended to USE the wireless internet, NOT the internet carrier

  The next time I switchd off the the carrier signal, and then Turned ON one internet WI - FI and then opened the web browser of BB. so now all the opend website with wifi internet bt as soon as I open YOU TUBE or FB or TWITTER.com it post a comment... .that cannot visit the web page when the carrier is off. Please turn on the radio n try again... I mean IT SHOULD OPEN with internet wifi? WHY do network carrier sim to open the web page?

  I have checkd my browser settings and they are default and also my wifi settings I have reset the... the problem still persists?

  any idea wats going on?

  Please help is needed I'm annoyed about this problem...

  Thank you

  MR. KIWI... Good news... .i went to my carrier service center... Solvedo Problemo!

  Go to your service books and remove directories of service WAP browser in all directories of service WAP 3 I don't know the exact name, but all are related to the browser... WAP config something like dat... Just remove dem... .and HARD restart your fone... and try to use only wifi on your device with your carrier network off...

  mine worked... Let me know on urs... so now, the browser uses my wifi instead of my network provider when both are running...
