• Wi-Fi not getting connected/ detected
• Wi-Fi disconnects with VPN/ when other devices connect – Sometimes problems with Wi-Fi can occur if you have multiple devices in your Wi-Fi network. Also, although a VPN is one of the best ways to protect your privacy online, it causes these issues, apparently.

If Wi-Fi is getting disconnected frequently that can be due to your security software.

Many third-party antivirus tools will interfere with Windows and cause various problems to appear.

To fix this problem, it’s advised to disable your antivirus and check if that solves the issue.

If disabling the antivirus doesn’t solve the problem, you might have to remove your antivirus software.

Keep in mind that uninstalling your antivirus software might not fix this problem because many antivirus tools tend to leave certain files and registry entries behind after you uninstall them.

To fix the problem, it’s advised to use a dedicated removal tool to remove your antivirus and all files associated with it.

Almost all antivirus companies offer removal tools for their products, so be sure to download a removal tool for your antivirus and use it to remove all files associated with your antivirus software.

After doing that, install the latest version of your antivirus software or switch to a completely different antivirus solution.

Computer-based random disconnect from internet

My computer disconnects from internet (not from my home wireless network) at random times, even though the Windows wireless settings status shows «connected to the internet». All other computers and devices in the house remain connected to the internet. I have done all the recommended wireless adapter checks as well as run and examined the wlan report. The sessions run various lengths of time, but in each case the disconnect appears to be preceded by the following event: Eventid:4042; Message: Capability change on (0x47008000000000) Family: V4. Capability: None ChangeReason: Capability Reset). What does the «CapabilityReset» mean in conjunction with my wireless adapter (Broadcom 802.11abgn Wireless SDIO Adapter, with most current driver re-installed)? How can this problem (frequent internet disconnects on just this computer) be fixed other than restarting the computer each time (works, but very annoying!)? I see many others on here with the similar issue, but none of the offered info (appreciated) and recommended «fixes» have worked. Thank you for any ideas on what the issue is and how to fix it.

PC Windows 10 disconnecting from internet

I have three windows ten pc’s connected to a wireless router. My desktop keeps disconnecting itself from the internet once or twice a day for no apparent reason. The other two laptops are fine, and never do. The difference between the three is that the Desktop was converted to windows 10 back when it was windows seven. Don’t know if that has anything to do with it or not. All the pc’s use Kaspersky total security software.

I can’t figure out why this keeps happening, any ideas?

To isolate the cause of this issue with your desktop disconnecting from the Internet, we would like to know the following information:

• Is your desktop computer connected to the wireless router via WiFi?
• Are you using a WiFi adapter on your desktop?
• When you experience this issue, does the desktop entirely lose connection to the router or it is still connected but doesn’t have Internet connectivity?
• Do you receive any error message? If yes, what is the exact error message that you receive?

Looking forward to your reply.
