Windows 10: ethernet becomes disabled after some time

Hi, i recently updated to windows 10. I'm having some difficulties regarding internet through Ethernet on It. what usually happens is i am able to surf the Ethernet for around 10 minutes, then the ethernet adapter just quits on me. So i run the network trouble shooter and find you that it needs to reset the DNS, which it does successfully. After that my Ethernet doesn't work anymore till I restart the Laptop. my computer's wifi card is an intel wireless n 7260, and the other network adapter is a pcie gbe family controller.

Windows 10 takes too much time on the windows login screen

I upgraded from windows 8.1 to windows 10 several weeks back, the booting time was blazing fast on windows 8 but after getting windows 10, it has become extremely slow! The welcome screen takes the most time with the dots going in circles but not loading.
The booting time has become 1 minute plus.

I thought that the boot up would become fast after some time but that isn't the case. I disabled all start up things but still no luck. Please help. I have an i3 HP Pavilion.

 

Internet connection issue

1. I need ethernet connection (over LAN without internet) for some reasons. So I can not disable it for normal work.

2. Modem is connected all the time. Only Windows not using this connection to access internet

3. After I unplug ethernet cable Windows immediately "switch" and redirecting internet access over USB modem (witch is connected all the time)

4. After plug back ethernet cable internet access imediately stop working (and modem is still connected)

5. I allready do Network Reset.

6. I update ethernet adapter driver

7. Before short time I discovered, that if I connect with WIFI adapter too, to some network witnout internet access, comunication over USB modem going withnout issue.

So the configuration with issue is: Connected USB LTE modem, Connected ethernet cable into network without internet. And no access to the internet. If I try ping 8.8.8.8, I see that DNS server of ethernet network is used, so this is the key, i thing.

It says ethernet is disconnected but it is connected to my laptop

 

Probably Windows Update replaced your Realtek drivers with Microsoft that are not perfect. Download latest drivers from Realtek (look for the Gigabit, PCI Express download) and install it. To prevent Windows Update replacing the driver again, hide the relevant update.
