Ethernet default gateway not available

I am using "Broadcom NetLink Gigabit Ethernet" on "Acer
Aspire E1-571G
" in Windows 10 OS.Since few days my internet connection is getting dropped when i troubbleshoot it fixes immediately showing "Problem Found-Default gateway is not available-Fixed" and starts working for 10 sec,1 min or sometimes 1 hr then again this problem.

Sometimes shows "Driver Power State Failure" error

my roomie has same laptop and same connection but no issues.

And even if i disconnect the wire it keeps showing connected icon in taskbar.

What i have tried already,
1.reset ip/tcp
2.Set ip adress manually.
3.Try to update driver from device manager says using best driver.
4.Reset my laptop.
5.Updated BIOS.
6.Unchecked "Allow the computer to turn off this device to save power" in device manager.

But problem still continues...

Can you tell me "WHY" this happenning?
and "WHAT" else can I DO?

Re: no connection

I don't believe your roommate uses your laptop (that's the same laptop). Do you happen to mean 'the same model'?

Anyway, the things to try are:
- System Restore back to when it still worked
- see what happens if you boot into a Linux disk. if it's the same, it's surely a hardware issue. if it's OK now, it most likely is a Windows issue.
- if a hardware issue: replace the motherboard or buy a new laptop
- If a Windows issue: go back to factory conditions

Two Things Come To Mind

One.. Because of the driver error message, try visiting the computer manufacturer's website and download and install their latest driver for your computer's network adapter.. If they don't have one, check at Broadcom to see if they have one which is updated for Windows 10.

If that doesn't fix it, then it's most likely a problem with the network adapter itself.. In that case, we purchase a inexpensive USB ethernet dongle for the computer, plug it in to the USB port, install the software it may, or may not come with, then use the new ethernet device to connect with.

Hope this helps.

Re: overheating

If you think the problem is related to a component being overheated (but why do you think so), you have 3 options:
- Don't overheat. Clean the fans and the inside, refresh the thermal paste, run it on a cooling pad.
- Replace the component that is too sensitive.
- Use an external USB network 'card'.
