Hello, i wanted a such big help from everyone q.q. IDK why this is happening to me, i tried searching everything to solve the problem. The problem is, idk if it's my network connections or my network drivers the only thing i know is, when i play online/multiplayer games and or when watching videos, my internet disconnects For Example:

So please help me q.q

Umm you should probably use better grammar and those are just pictures of your realtek network adapter.
When it happens, try to troubleshoot the problem by right clicking the wi-fi icon and clicking "Troubleshoot"
Tell me what happens after.
Also, are you playing games via wi-fi or ethernet?
Your routers settings may be on high. If it is, any large loads on the router may result in this.

Oh sorry got the grammar mistakes i am not good in English 'cos it's not my language >.> also it's Ethernet. I don't know about the router settings :/ Also i found that, i was not getting disconnected while that Ras Async Adapter was on.

It turned off and i am starting to get disconnected, so is there any connection with this Ras Async Adapter?

May I know your router speed? Also, you may either: Need to uninstall your current network adapter and re-install the latest version from the manufacturer's website. Or you may have a failing network card. That's highly unlikely since you are using ethernet but it's still an option. Do you know your router's name?

And no. Ras Async Adapter has little to no connection with internet.

I don't know how to check router speed D: is there anyways to check that? also i have tired uninstalling the driver and installed new drivers. i don't if i have a failing network card >.> btw is this my router speed http://i.imgur.com/Jl9Ud5G.png ?? (I am so confused, Router is Cable Modem?) if yes then, Router name 'Cisco'

oh my god if that's your speed buy better internet package!
