Based on in depth testing the tp link archer c2300 is the best wi fi router overall due to its superb performance and extensive feature set.
How to get wifi through concrete walls.
My idea is to install a second ac1200 range extender drill a hole in the wall and connect up the 2 extenders via ethernet cable i e.
It could be due to the material used for the wall or other physical barriers that block or weaken wi fi signals.
Solid concrete or brick walls good for building but not so good for wi fi that s why we have researched and found many wireless routers then we tested and sort listed them to provide you guidance on the best wireless router for thick walls.
Materials such as drywall plywood other kinds of wood and glass can be easily penetrated by wireless signals.
However even though this is positioned less than 5 m from the ap the signal is poor probably because it has to go through a brick wall.
There are extenders either side of the wall.
It has a strong range and can easily get to where you need it to go through any wall.
Older houses that mysteriously refuse to let wi fi signals pass through their walls might have a hidden ingredient.
However in reality some walls are thicker or use reinforced concrete and may block some of the signals.
This is a versatile router that provides all of the supports that you would really want to get from your home router.
Concrete with and without metal reinforcement is one of the worst building materials for wireless signals to pass through but masonry block and bricks can also be serious barriers for wi fi.
