Horrible WIFI Signal Strength after installing Windows 10 PLEASE HELP

Hello everyone,

I have just installed Windows 10 on my laptop Acer Aspire V5-552P-X440 and since then my WIFI signal strength has been terrible. I have a range of about 10ft in open space from the router before the signal is lost.

The adapter is an Atheros AR5BWB222 (Driver Version 3.0.2.182)
Router used... Linksys E2500. (Multiple trials on different home networks. Same results.)


What I have tried so far.

• Removed original Atheros driver, and let windows 10 install their latest.
• Downloaded and installed latest drivers from Acer website.
• Removed/uninstalled Bluetooth drivers (Read about possible conflict)
• Disabled all VPN Services (Read about possible conflict)
• Disabled Firewall and Security application. (AVG Internet Security)

Right now I am at a loss. I really don't like Windows 8.1 but might have to go back to this.
Anyone have any ideas?

Thanks TairikuOkami for the quick reply!

I will give this a try and follow up.

Change the channel to the one, which is the least crowded, use this tool to see, which ones are.

Disable IPv6: Run CMD as admin and enter:

netsh int ipv6 isatap set state disabled
netsh int teredo set state disabled
netsh interface ipv6 6to4 set state state=disabled undoonstop=disabled
reg add "HKLM\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters" /v "DisabledComponents" /t REG_DWORD /d "255" /f

Another separate question if you can help me on this too.
Since the "Upgrade" to Windows 10, I have noticed that the NUM lock key is disables on startup. I tried to make the Registry key change on the InitialKeyboardIndicators to value of 2, as mentioned in numerous google searches.
I though I had this fixed until I powered off the laptop. Is there a fix for this?

Thank you again for all your time and help!

Okay, I tried the WIFI at home and the signal strength looks better in terms of detecting networks and having more "bars" however, if I am behind one door, 10ft away from the router the connection is lost.
Open air (No walls) I can get about 40ft but with very low signal.

Any other ideas I can try to resolve this?

Thanks everyone for the help. No luck.
I am just going to purchase a cheap USB WIFI adapter and call it good.

Hi there

This is also an easy graphical GUI to use

1) Disconnect from your Wifi network
2) run the program called Vistumbler get it from here : Vistumbler - Downloads

You should get something like this:



Select channel least used - usually 1,6,11 are the most used, 13 is fine in USA that might not be an allowed channel, in Europe - it's OK.

Note though channel 13 might not also work on some Linux distros if you are using Wifi on a NAS / Linux server - switch to 1,6,or 11.

You could also try if your router permits going up into the 5MHZ band - make sure you have a computer to re-connect to your router if your wifi card can't manage the 5MHz wifi -- you can often in an emergency also logon with a mobile phone as their wifi is probably a lot more modern than typical computers and reset your router.

Ideally if you can get one of the new hi-speed ac protocal adapters then your wifi problems should be over - the latest usb3 wifi adapters can run at nearly LAN speed (internally).
