Why Windows File Transfers Slow Down and How to Fix It

Have you ever tried transferring files between PCs on a network, only to watch the speed drop to zero or crawl at an agonizingly slow pace? It’s frustrating..

Recently, I encountered this issue while moving files between two networked Windows PCs. After some troubleshooting, I found that mixed RAM capacities in the system played a role, but there were also network-related factors slowing things down. Here’s what I learned and how you can fix similar issues.

Check Your RAM Configuration

One of the first things I did was run a memory test. While the test showed the RAM was functioning correctly, I noticed something unusual—two of the RAM sticks were 2GB each, while the other two were 8GB each.

Why is this a problem?

• Mixing different RAM capacities forces the system to run at the speed of the slowest module.

• This can impact overall performance, including network file transfers.

For optimal performance, it’s best to use RAM sticks with the same capacity and speed. 

Mixing RAM modules of different sizes, like 2GB and 8GB, is possible but may not provide the best performance.

Many modern motherboards support dual-channel memory, which boosts speed by running paired RAM sticks together. However, when using different capacities, only the matching portion operates in dual-channel mode, while the remaining memory runs in single-channel mode.

Although this setup works, it can reduce the benefits of dual-channel performance and may slightly impact system stability. The motherboard has to manage the memory asymmetry, which can lead to less efficient performance overall.

By removing the 2GB sticks it resolved the issue, restoring transfer speeds to normal in my case.

Setting Up Bitvision NVR And App

Before we can add a device to the phone we need to make sure the NVR is online (on the Net). 

From The NVR

Using the mouse Login to the NVR:  The default user is : admin and password is 12345

Then make your way to

  

Or From Microsoft Edge Browser

This can be daunting as web browsers have too much security and it may take some time to get it to work but follow along if you can.

Use Microsoft Edge as Chrome is not a well supported I found

Type the IP address into the NVR : if you’re not sure on how to find your IP address of the NVR you can either find it in the Network settings of the NVR or you can use the Bitvision search tool.

https://www.dropbox.com/s/tpuc1ebleopwbvk/SearchTool%20for%20WIN_V1.5.1.230221_R1.exe?dl=0

After installing the Search tool run it. As you can see my IP address is 192.168.0.244

Once you know your IP address type it into the browser (don’t use this IP address use yours) mine is http://192.168.0.244/login.html  

Type in your username and password and if you haven’t changed yours yet (Please do) default is admin and password is 12345

Once logged in it should look something like this unless you have different firmware.

Make your way to Configuration then Network then P2P, P2P must be ticked (enabled) and your status must say Online, if it does your good to go no port forwarding necessary (you only need to port forward if you have changed the HTTP port to something else besides the default (80) in Network settings.

The below screen shot may be slightly different to yours, you may have the QR codes one for Android, IOS and serial Number or combined like this one. 

Default ports listed below – Your IP address and gateway will match your configuration

Your gateway is of course you Modem IP address – In my case my modem is on a 0 Dot network so the NVR is on the same 0 Dot network.

Time to install the app

Scan the Android/IOS QR code in the Configuration /System/Network/P2P screen or using you mobile search for Bitvision in the app store.

Must register an email address to the app.

    

From the left hand panel select “Device manage” then click (add +) then SN Add(recommended)

   

From the NVR go to network then P2p and scan the Serial QR code or from web browser go to Configuration /System/Network/P2P screen and scan Serial QR code

Helpful notes

iVMS320 software is PC client for Bitvision device with S/N starting with "8"

VMS lite is for freeip device with S/N starting with "9".

Uppercase, Lowercase, And Capital First Letter Excel

 Change text to either UPPER, lower, or Proper case.

Enter the below formula to column B

=LOWER(A1)

=UPPER(A2)

=PROPER(A3)

****************************************************************

=LOWER(A1) will change text case in CellA1 to lowercase

=UPPER(A2) will change text case in CellA2 to UPPERCASE

=PROPER(A3) will capitalizes only the first letter in each name in CellA3 

Move Cell Text Into Separate Columns

 Highlight the text in the column you want to seperate in my case A2-A4 

Then Hold Down ALT and A ,then press E  twice, a convert to text box wizard appears, click next

Then next again

Then finish

Add Space Between The Number And Text Excel

 Add values in column A1 then in select B1 and add this fomula to the formula bar marked in Red then press enter.

Now while holding left click (marked in green) then drag down to include all cells with updated formulas 

You should now see the numbers seperate from the text.
