TL-WR841N Model router am using, I have 75Mbps speed internet connection. But only 35Mbps speed coming.
I tested with direct LAN cable then am getting around 80Mbps speed.
Through LAN cable from wifi router am getting 75Mbps speed.

Please help verify some details, and we will try to fix it together:
1. How did you test this Wi-Fi speed via the router? Did you disconnect all the other devices from it and only leave one laptop or phone performing the test? It is suggested to change a new SSID and password and connect only one phone or laptop to perform the speedtest 3 times.
2. How about the wireless negotiation speed on that device? If the link speed is not as good as expected, please try another wireless device with more powerful wireless cards.
3. Please simplify your network layout if there are other routers or RE in your network, just leave the modem and the WR841N on, disconnect other devices and run the Speedtest app 3 times. Please ensure the wireless channel width is set to 40MHz. Here is the guide to modify the wireless settings on the router:

Thanks for replay,
Yes tested with only one laptop and disconnected all device from wifi connection.
Through wifi tested speed using https://speedtest.net. link.
But with direct LAN cable through router port am getting as expected speed. On router it is specified should support till 300Mbps.
