How to improve the speed on TP-Link?
Firstly try and change the position of the antennae’s on the router. This does help or you could change the location of the router. Most times you will place the router in the middle of the house or where you will use the router the most. You can also add a repeater from TP Link which simply plugs into the wall. This will extend the range. See the TP Link range extender. If this does not work then try the next step.
Secondly look around and see if there are other devices that are also using 2.4GHz. They might be affecting your connection as they might all be using the same channel. Different wireless channels will have different performance.Thinks that use minimal WiFi you might consider changing these to lower channels. When you have channel crowing it becomes a problem especially if you live in a condominium as everyone will be having WiFi and they might all be using the same wireless channel. Change this on your computer as there are usually WiFi Mode, Channel Selection, and Channel Mode.

You will note that the 2.4 GHz band which are channels 1, 6, and 11 are normally the best as they don’t overlap with each other. When it comes to the 5 GHz band you have far more choice as there are 24 non-overlapping channels for this range. Log into your TP router and then choose a channel and then check if you are getting better speed. Most times it has been set to auto which you can change manually and test again. You can then test the speed with the NetSpot app if you wish to test it further.
