Of course you first need to check there is nothing wrong with the server. If you can’t find an issue there, what else can you do to regain access?
The first thing to do is always restart your computer. This – for no apparent reason – will fix a lot of issues.
Do you have Avast?
Avast has a nasty habit of blocking my server when things update. Head across to Avast Firewall is Blocking Network Share. Windows Report explains very clearly how to resolve this issue.
Sorry there is no picture for this. I don’t know what I’m allowed to screenshot for copyright, so you get a blank screen for this one.
Do you have a Mesh Network
Our mesh network has given us a much improved Wi-Fi experience. We have an odd shaped house, and wherever we put the extender, we had dead zones in crucial spots.
Mesh works very well. Some of the devices will automatically switch to the nearest node if you move around. But our laptops tend to hang onto the one they’re connected to. So when you move, sometimes you need to disconnect and reconnect to pick up a nearer node.
I’m trying to find a source to explain this. But in Avast, it refers to nodes by mesh_name1, mesh_name2. In other words somewhere there is a node name which maps to the mac address of the node. And when you change, it is getting a new alias to the network. Now these numbers are increasing in the Avast firewall, and I need to find out where to find more about the actual connection is stored. Perhaps this place needs cleaning out. But I need to find an IT expert to find out more.
