Slow internet connection / download speed with Broadcom BCM43142 802.11 bgn

[LeonCray]

Hello everyone

I've bought this PC 2 years ago which included the default Win8 version.
Then, I upgraded to Win8 Pro.

At the beggining I had no troubles using it, but lately I had some sort of problems related to WiFi drivers

When I had Win8, drivers couldn't even detect most of the networks neraby PC, and when it detected mine (and managed to connect to it) connetion was very slow and couln't even open any server (like Google or HP forums) I kept trying drivers diferent recomended drivers (from the Download Center) and any of them worked properly; they solver the issue for a little time and then the problem comes back.
I got tired of it so I decided to try Windows 10, but now I'm a way similar problem connection is good, but download speed is something like 62kbps (I have a 10mb speed network). This is making me crazy.
I download all my driver from the Official Download Center provided by HP, and any of them work properly. Does anyone have any suggestion?

Might not be an important thing, but it could be an extra info: my battery has ended its life, so it doens't recieve any charge.

Current driver: Broadcom BCM43142 802.11 bgn

Don't worry I'm here to help you out.

Did you make any software or hardware changes on your PC?

Are the wireless drivers listed in device manager?

As you mentioned the download speeds are very slow on your PC.

 Try updating the BIOS and wireless drivers on your PC and check if it helps.

Uninstall the wireless drivers from device manager and install the drivers from the links below.

Try the steps recommended below to solve the wireless issue with your PC.

Change channel width for your network adapter

“Windows 10 can’t connect to this network” message sometimes appears if the channel width of your wireless adapter isn’t set properly. To change the channel width, do the following:

Press Windows Key + S and enter type network. Chose Network and Sharing Center from the list of results.
When Network and Sharing Center opens, click the Change adapter settings.
Locate your wireless adapter and right click it. Choose Properties from the menu.
When Properties window opens, navigate to the Advanced tab.
Select the 802.11 channel width and change the value. Some users have reported that changing the value to 20 MHz has fixed the issue for them, but you might have to use a different value.
Click OK to save the changes.

Disable IPv6 on your computer and router

To solve “Windows 10 can’t connect to this network” error, sometimes you have to disable IPv6 network protocol. To do this in Windows 10, follow these steps:

Open Network and Sharing Center.
Find the Connections section and click your current connection.
Connection status window will open. Click the Properties button.

Click OK button to save the changes.
Restart your computer in order to apply the changes.

Click the Start Button.

Click Continue if prompted.
Click the [+] next to Network adapters.
Right Click on “Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC” or similar Wireless card.

On the right-hand side change the drop-down menu to “IEEE 802.11b/g”.
Click OK.

Manually change network settings

Manually changing the network settings can resolve wireless connection issues. Create a restore point in Windows, and then manually change the network settings.
Using the search box on the taskbar, search for and open Create a restore point.
The System Properties window displays.
Click Create.
Type a name for the restore point, and then click Create.
Windows creates the restore point.
Using the search box on the taskbar, search for Command Prompt. In the results list, right-click Command Prompt, and then click Run as administrator.
If a User Account Control screen displays asking if you want to allow the app to make changes to your computer, click Yes.

Type the following commands one at a time, pressing Enter after each one.

ipconfig/flushdns
nbtstat -R
nbtstat -RR
netsh int ip reset c:\resetlog.txt
netsh winsock reset
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
To open the TCP Global Settings, type netsh int tcp show global in Command Prompt and then press Enter.
Make sure all settings are disabled except Receive-Side Scaling State.
Close Command Prompt, reboot the system and then try to connect to the Internet.

Forget the wireless connection

If you’re having “Windows 10 can’t connect to this network” error, you might want to “forget” your wireless connection in order to fix this problem. To forget wireless network on Windows 10, do the following:

Open Settings App and go to Network & Internet.
Go to Wi-Fi section and click Manage Wi-Fi settings.
Scroll down to the Manage known networks, select your Wireless network and click Forget.
After you’ve done that, connect to the same wireless network again.
