Laptop disconnects from WiFi frequently

[Lankesh]

Hi everyone,

My office laptop disconnects frequently from my home WiFi whereas my personal laptop has no problem.
One strange thing is, once my office laptop is disconnected, all other devices like mobile phones, etc. stop working. They show "No Internet" message. You won't be able to browse internet on them.

So far, I have tried to
Uncheck the checkbox - "Allow computer to turn off this device to save power" for the Wireless adapter.
But no effect.

Updated all the drivers - no effect.

Is there anything that I should try now?

Office laptop configuration - Dell Latitude 5590, Windows 10 Enterprise 64 bit
It also has Cisco AnyConnect that is used to connect to office WiFi in all office premises.

Any help appreciated.

Thanks.

Look for updated firmware to your router

I have a Latitude 6530 that I actually had to uninstall the dell drivers and when connected via ethernet let windows install the drivers to fix the exact problem you describe. For me the problem was the Dell drivers.
