The 5 GHz band is now being used by routers to help relieve the congestion found in the 2.4 GHz range.
The problem with 5 GHz routers is that they dont transmit a signal as far as the old 2.4 GHz.
2.4 GHz vs. 5 GHz
As stated above a signal in the 2.4 GHz range can travel farther than a signal in the 5 GHz range.
This is due to the physics of wireless signals, with signals on lower frequencies able to transmit farther.
The problem with the 2.4 GHz range is it has become over used and is now very over crowded.
Routers are not the only thing that crowds the 2.4 GHz range. Other electronics from radio controlled helicopters to TV remotes also commonly use 2.4 GHz to send a signal.
In such a crowded environment a 2.4 GHz router will have to overcome all the other 2.4 GHz devices to get a signal through.
Any packet a router sends that collides with another signal will have to be resent by the router which slows it down.
For this reason 5 GHz has been introduced which is relatively unused.
But as stated above a signal doesn’t transmit as far in the 5 GHz range which leads to problems for users who need distance from their router.
Five Things To Check To Increase WiFi Range
All router manufactures have different setups and options but here are some basic things that can be checked.
First be sure your client (laptop, tablet) is logged into the 5 GHz side of the router. Dual band routers use 5 GHz and 2.4 GHz to transmit and receive a signal.
The easiest way to be sure you are logged into the 5 GHz side of a router is to change the broadcast name in the router itself. Such as adding a 5 to the 5 GHz brodcast signal and a 2 to the 2.4 GHz broadcast Id.
Some routers have a option to increase the signal strength. Not all routers have this options but if yours does increasing its signal strength should give you a boost.
The location of the router effects its range. Setting it 4-5 feet from the floor will help with a signal.
Routers that have external antennas can be adjusted to try for a better signal. Larger antennas can also be bought which can help improve the distance they transmit.

Check the client side settings (laptop, tablets) and that their wireless cards are compatible with 5 GHz and can use the new 802.11ac protocol.
Wireless Signal Boosters
A WiFi signal booster can be setup to boost a wireless signal.
If you go this route than be sure that the WiFi booster matches your routers protocols.
Most new routers will support 802.11ac along with 802.11g and 802.11n.
There are universal WiFi signal boosters that work with most any router. Here is one such signal booster.

Boosting a 5 GHz WiFi signal greatly depends on the router that is being used. All routers are not created equal when it comes to signal strength.
While there are many things that can be checked to increase a signal sometimes the router itself may be a dud.
