A bit strange problem has occurred on my Y550.
When trying to connect y550 to a D-Link DIR-301 router (whether via Ethernet or WiFi), the connection on router crashes and becomes invisible to other computers for a short period of time. Then connection stands up but overtime y550 attempts to get through it crashes over and over again.
Y550 connects to router (sometimes there is access to the Internet - sometimes connection is limited) but only for a few seconds before connections crashes. It works fine on any other router I've been using e.g.. Asus.
At first I thought this problem was caused by assigning dynamic IP but after setting up it to static values the problem still occurred. I have checked any possible issues with power management (on network adapters, power plan, with and without battery). Drivers update also did not bring any effects.
Ip config shows nothing, as if it was not connected (I called it during that short period when y550 was connected)
Eventually I found out that connection works fine in Safe Mode so this must be some software/driver issue.
I've used one key recovery and brought y550 to it;s original fresh out-of-the-box state and problem still occurs (even after updating drivers again.
No drivers available via lenovo.com helps.
I've read nearly 3/4 of the entire Internet seeking for solutions - couldn't' find anything.
One step left for me to check is remove Intel software which manages connections.
Any ideas guys?
