Does this device have native 64-bit Windows 8 drivers? – Ramhound Sep 4 '13 at 12:33
devices says that its support max, linux,xp,win7,win8 32bit and 64bit, but i don't think so – dev.mraj Sep 4 '13 at 13:06
If the device says it supports Windows 8 64-bit hat makes you think it does not have native support for Windows 8? – Ramhound Sep 4 '13 at 13:53
still i am searching a lot, i think it may be possible that winsock may get corrupted, i am in office now, at home i will check if resetting winsock works or not, because i see on internet that many users are facing same problem like me and those are caused by winsock – dev.mraj Sep 4 '13 at 14:19
just wait for a few hours i will put all details informations here – dev.mraj Sep 4 '13 at 14:21

Sometime due session layer like basic protocols winsock and ip get corrupted that cause internet not to work, it seem like data is coming and going but not corrects packets, to solve this i used this methods

run this commands as admin

netsh winsock reset


netsh int ip reset c:\resetlog.txt

that worked for me atleast

you can also try uninstalling those protocls from nic, and installing again, which is 'Internet Protocol version 4' in networking tab
