This is a problem i had started having about a week ago.
No new software has been installed or deleted.
My router status light usually blinks and the net stays connected for about 10-15 mins
before it gets frozen on either light on or off and the net gets disconnected.
This takes place only when the ethernet wire is connected to the laptop ( Dell N4010 ) otherwise the light keeps blinking away merrily.
The laptop is about a month old and internet worked fine for quite some time.
If i switch the router off and on it again stays for some time and again gets frozen.
The time for which the net stays connected rarely varies.
Tried a different router but the same issue.
