very weak wifi signal strength

[siddharth874484]

Have been using the laptop since almost a year and the wifi signal strength used to be great but recently the signal has been very weak with only one tiny bar when sitting next to the wifi router. earlier it used to have very strong signal in the same position. The router is fine as it is working well with every other device. Also, the internet speed is as it was, despite the weak signals but internet gets disconnected going even a little far from the router..

product name & number: HP Notebook 1AC75PA#ACJ    

driver: Realtek RTL8723BE 802.11 bgn Wi-fi Adapter

OS: Windows 10 (64-bit)

The driver is up to date. I have tried a number of fixes but nothing has worked thus far.

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.
Find Internet Protocol Version 6 (TCP /IPv6) and uncheck it.
Click OK button to save the changes.
Restart your computer in order to apply the changes.

Click the Start Button.
Type “Device Manager” and press Enter.
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.
Click Properties.
Click on the Advanced Tab.
Click on 802.11d.
On the right-hand side change the drop down to Enabled.
The  following steps are optional but may help:
Select TX power level.
On the right-hand side change the drop down to 100%.
Select Wireless mode.
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, typenetsh 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.
