4 outlets and 2 switches not working

Officially, wiring is done in a tree topology - each segment branches off another. However, in practice, most wiring is done in a vine topology -- they're all in a row.

Either way... the problem is in one of two places.

• The last receptacle which works
• The first receptacle which does not work.

Fiddling with any other receptacles won't do a thing.

That's because the problem is in the wire or the wire ends/splices. Failure of a wire is extremely rare. It's almost always where the wire connects to something else.

The usual cause is a "back stab" wire connection into the socket: the kind where you jab it into a hole and the socket just grabs the wire. Backstabs are legal way to wire sockets - one time - but they're not very reliable*. It is much, much better to use the side screws.

* Backstabs are made for a single use. If you pull the wire out, the spring is sprung. Also, when you are shoving the receptacle back into the socket, forces on the wires can lift it off its intended contact area, or overload the spring and cause it to lose tension.

It appears from your most recent fault status report that you have an open or intermittent hot lead somewhere from the last outlet in the close bedroom to the first outlet in the far bedroom. Here are some possibilities to check:

1. If any of the the electrical outlets in question are using poke-in-and-leave-it type wire connections then rewire those connections to use the side screws with the wire under the screw head. Some types of outlets also have a screw tightened clamp on the side that the wire will feed straight into from the back.
2. Contemplate of any remodeling in this area of the building has been done recently. A nail or a screw inserted in just the wrong place could have severed the hot lead in power feed cable in the wall or passing through a stud.
3. Consider temporarily disconnecting the wiring between the last working outlet and first on working outlet. Then run some temporary wire between those locations as a debug to see of a new wire works.
4. There is always a chance that part of the faulty wiring run can be traced and inspected. It may even route up into an attic or unto the crawl space where through the wall stud routing is blocked due to doorways. Wires in these areas may be more susceptible to damage due to human activity, pest access to wires or poor routing of a cable over a sharp metal edge.
