This constantly started to happen some time ago. I connect to my router andand lose every few seconds connection to router and it reconnects again. I have screenshooted most errors that Event Viewer reported. First comes overview:
And now 3 events that happened at the same time:
As you noticed, all 3 came at same time, when first was warning saying something about semaphore timeout, second was about losing lease and last was about NAT.
After several minutes of this happening, i could not connect to router as NIC showed that it was aquiring address and just repeated connection attempts until i just had to cancel connection. You can see this in Event Viewer:
This problem happens with other hotspots as well.
