Check whether you are connected to a public network, if you try connecting to a Private network, this should fix it.
- Type 'network and sharing centre' in your windows start search box.
- Try to locate Words like Private network, Public Network or Home Network from the box to the right.
- Next if you see public network, click on it and select Private Network and try connecting to your Private space.
It also might be because your LLTD protocol is disabled in the network adapter.
You can get that to work by following these simple steps: -
- Type 'network and sharing centre' in your windows start search box again.
- To the right Click 'change adapter setings' and select ' local area connection'
- Right LAC and check 'link-layer topology discovery mapper I/O driver' & 'link-layer topology discovery responder' boxes and the OK.
Lastly, check if your network discovery is on or not and that's it.
Try all these and get back to me with the results.
