Low Wi-Fi speed from TP-Link TL-WR740N
Provider’s speed 100 mbps, modem speed 96 mbps, router speed in wired mode (that is, the computer is connected to the router by wire) 88 mbps, speed in wireless mode 15 mbps.
What is the problem?
Answer
Your problem is clear. You need to understand that Wi-Fi speed will always be slower than cable. This is normal. But how much lower it is depends on the router, the device you are connecting and a lot of external factors (interference, signal strength, etc.).
Next: TP-Link TL-WR740N is a budget router. And it’s not strange at all that the speed is only 15 Mbps. Did you check the speed only from one device? Maybe on another device the speed will be higher, and the problem is not in the router.
What you can do in this case: update TP-Link TL-WR740N firmware. Also try the tips from the article how to increase the speed of Internet over Wi-Fi through the router.
Perhaps after these actions, the speed from the TP-Link TL-WR740N router will be a little higher. I think this is all that can be done in this case.
But you should not expect great speed over Wi-Fi network from this router.
