How to fix slow 802.11n wireless network speed

Many people ask me about this, they have a 802.11n equipment with declared speed of 300 Mbps but yet when they are connected to their wireless network their speed seems to be a lot smaller.

Here are the few things you should check if you think your network is to slow.

  • Are both the wireless network card on your device and the access point you’re connecting to 802.11n. If you have a 802.11g card then there is no use of having a 802.11n standard AP. Same principle applies in the other direction, if you have a 802.11n card and a 802.11g AP
  • Are you using non-WPA2 security.
    802.11n standard prohibits the use of TKIP and WEP on wireless network. All network cards that are certified for the 802.11n by the WiFi Alliance will either not connect at all to the wireless network that uses WEP or WPA as the security, or they will fall down to 802.11g standard which has the maximum speed of 54 Mbps, like you can see at this Intel statement
  • Don’t disable the WMM/WME, WiFi Multimedia or Wireless Multimedia Extensions is something that 802.11n devices have to have enabled to be certified for 802.11n.
  • Check if your access point is using some sort of power saving, some access points will work with slower speed if you put them on some sort of eco/ power saving mode
  • Mixed mode, this is a much debated issue, some claim that configuring your AP to work in mixed mode (to also work with older 802.11b/g clients) will automatically drop your speed down. Some claim that it only happens if you have 802.11b/g client connected to network, and some claim that it doesn’t happen at all.
    Nevertheless if you only have 802.11n clients don’t put your AP in mixed mode.

If anybody has any suggestion for any other options or settings to take in mind when the connection is slow, feel free to add them in the comments.

How to scan over remote desktop connection

In this post I present you TerminalWorks TSScan.

There are free alternatives how you can use your local scanner on the remote machine, like Microsoft RemoteFX USB Redirection, but this eases the setup for regular users significantly.

With TSScan you can use your local scanner that is installed to your windows machine to scan in the applications that you run on the remote machine to which you are connected with a remote desktop connection.

To be able to scan over remote desktop you need to download the server and the client package from their website and install it to your machines

TSScanDownloadPage

TSScan Client package needs to be installed to the machine where your scanner is installed, and the TSScan Server file needs to be installed on the remote machine to which you are connecting to with remote desktop.

After you install the TSScan Server to you remote machine you will get a TSScan application shortcut, on your desktop and in your Start Menu,  which when you start should give you a drop down menu with the selection of the scanners that are installed on your local machine.

TSScanGUI

You should also be able to see either TSScan or the name of your local scanner directly in the scanner selection of the applications you use on the server, if they have image acquire option.

The supported Operating Systems for TSScan Server are Windows 2008 R2 Server, Windows 2008 Server, Windows 2003 Server, Windows 8, Windows 7, Windows Vista, Windows XP.
The supported Operating Systems for TSScan Client are Windows 8, Windows 7, Windows Vista, Windows XP, Windows 2000, Windows Embedded

You can also use TerminalWorks TSPrint solution to use your locally installed printers on the remote machine over remote desktop.

Windows 7 USB/DVD Download Tool error: We were unable to copy your files. Please check your USB device and the selected ISO file and try again

I have written about how to make a bootable USB installer for Windows 7 and 8 by using the     Windows 7 USB/DVD Download Tool. Sometimes if your USB stick has something in its MBR you might get the error

We were unable to copy your files. Please check your USB device and the selected ISO file and try again.

I found the solution to that problem in this post.

You have to start command prompt as an Administrator (On Windows 7 that means right clicking the cmd and selecting Run as Administrator) and use the diskpart utility.

  1. Start command prompt as Administrator and type  diskpart 
  2. type  list disk
  3. type select disk  and number of your USB disk ( like select disk 1 )
  4. type  clean
  5. type  create partition primary
  6. type  select partition 1
  7. type  active
  8. type  format quick fs=fat32
  9. type  assign
  10. type exit  to exit the diskpart utility
  11. type exit  to close command prompt

How to make a bootable USB thumb drive with Windows, Linux or some other operating system or utility

In one of my previous posts I wrote how to put a Windows 7/8 installation on a USB stick with Windows 7 USB/DVD download tool.

Now I present you Universal USB installer.
It is a tool for an automatic creation of bootable USB installations or Live Linux distributions.
It supports a wide array of different Linux distributions and operating systems like Ubuntu, Mint, Debian, Backtrack, Fedora, OpenSUSE, CentOS, Windows Vista/7/8 and some rescue software and utilities like Hiren’s Boot CD, Ultimate Boot CD, DBAN and many others.

The program is very easy to use, you simply plug your USB stick in the computer, run the program, select the desired operating system or utility, select the location of the ISO file (you can also select to automatically download the unnecessary ISO file if you don’t have it) and select the drive letter of the USB stick which you want to make bootable.
With some OS like Ubuntu you will also have a option of setting the size of the persistence file so you can store changes you make to your OS.

Universal USB installer optionsNotice:
Program by default only shows you drive letters for external storage, but If you plug your USB stick after you have run the program, you won’t have the option of selecting it from drop-down menu in step 3, in that case you will either have to mark show all Drives option (be careful not to select the wrong letter), or start the program again.

You can download the program from here
