Why does my WiFi die in the back bedroom?

Your WiFi dies in the back bedroom because of distance and walls, not because your router is cheap. Every wall a signal passes through costs strength, and by the time it has crossed three or four of them it does not have much left. Buying a more expensive router almost never fixes it, because the problem is where the signal starts, not how loud it is.

That is the short answer. The longer one is worth reading if you are about to spend money on this, because the fix depends a great deal on what your house is made of.

Why doesn't a better router solve it?

A router broadcasts from one point. Signal strength falls off with distance no matter what, and drywall, cabinets, appliances, tile and mirrors all take a further bite out of it. A router that claims to cover 3,000 square feet is describing an open field, not a house with rooms in it.

There is a second problem people rarely hear about. Even where the signal reaches, the connection gets slower the further out you go, because a weak link falls back to a slower, more reliable data rate to stay connected at all. So the back bedroom shows two bars and everything crawls. The bars are telling you it is connected. They are not telling you it is usable.

Does it matter what my house is built from?

In the Tulsa metro it matters more than almost anywhere, because the housing stock splits so cleanly.

North of 51st, the oil-boom neighborhoods around Maple Ridge, Swan Lake, Brookside and Cherry Street were mostly built between 1912 and 1932. Those homes have thick plaster walls, often over metal lath in later or repaired sections, and many are brick. Dense plaster, metal lath and masonry all block wireless signal far more than drywall does. A single router in a 1920s Midtown house almost never covers it, and no amount of money spent on that router changes the outcome. Homeowners in these neighborhoods often assume something is wrong with their internet service when the service is fine and the walls are the problem.

South of 51st, the post-1970 subdivisions are drywall over wood studs, which is far friendlier to wireless. The problem there is usually size and shape instead: a long two-story floor plan with the router in an office at one end, and bedrooms at the other end of the house and up a floor.

Sand Springs adds a third case, with older bungalows near McKinley and downtown carrying the same plaster problem on a smaller scale, plus hillside homes where the equipment can end up two floors away from where people actually sit.

Is mesh WiFi good enough?

Mesh is genuinely better than one router, and genuinely worse than the alternative.

A mesh system puts extra nodes around the house, and each node relays traffic back to the main unit. The catch is that a node talking wirelessly to the router has to both receive and resend everything, which on many dual-band systems roughly halves the available speed at each hop. Tri-band systems with a dedicated backhaul radio lose less, but still lose some. That is why a mesh node can show full bars and still feel slow.

Mesh makes sense when running cable is genuinely impossible. It is a compromise, and it should be chosen deliberately rather than as a default.

What actually fixes it?

Wired access points. Instead of one router shouting from the corner of the house, you place two, three or four small access points around the floor plan, each connected back to a central switch with Cat6 cable. Every access point gets full speed because it is not relaying anything wirelessly, and your phone hands off between them as you walk.

The design questions are how many and where, and those are answered by walking the house rather than guessing from a floor plan. Integration at Work, AV takes real signal measurements on site, because the spot that looks obvious on paper is often blocked by a chimney, a stack of ductwork or a wall of kitchen appliances that no drawing shows.

In a finished home, the cable usually runs through the attic and drops down inside a wall, which is why most homes in this metro being slab-on-grade with an accessible attic works in your favor. There is no crawlspace to work with, but there is almost always a way in from above.

How much does this cost in the Tulsa area?

A typical whole-home network with two to four access points, a managed switch and a small rack runs between $3,500 and $9,000 installed. Larger homes, acreage properties, and anything that needs buried conduit out to a shop or guest house generally land between $10,000 and $30,000.

What moves the number is how many access points the house needs, how many new cable runs are required, and whether the walls are open. A house under construction is dramatically cheaper to wire than the same house finished.

What about my pre-wire? Doesn't my house already have this?

This is the most common surprise in the metro, and it catches people in Broken Arrow, Jenks, Bixby and Owasso constantly.

Homes built roughly between 2000 and 2015 were very often sold as pre-wired. In practice that usually meant RG6 coax and Cat5e, run for how people watched television in 2005. Cat5e handles gigabit internet fine, but it is marginal for sending 4K HDR video around the house, which equipment makers now specify on Cat6 or Cat6A, and a coax run to a bedroom wall plate is a dead end rather than a network.

The good news is that some of it is usually reusable. Integration at Work, AV checks what is actually behind the wall plate before recommending anything, keeps whatever still holds up, and pulls new cable only where it is genuinely needed. Most homes do not need a full rewire. They need three or four runs done properly and a real network behind them.

Should I do anything before calling someone?

Two things worth trying first, because they are free.

Move the router. If it lives in a closet, a basement corner or behind a television, moving it to a central, open, higher spot can make a real difference. Central and high beats hidden and low every time.

Then check what you are actually paying for. Run a speed test standing next to the router. If that number is close to what your plan promises, your internet service is fine and the problem is entirely inside the house, which is the situation the rest of this article describes.

If the number next to the router is also bad, call your provider before calling anybody else.
