Description:
We need to start with the fact that TP-LINK TL-WR840N is exclusively a router for a small home or office. If you need to organize the distribution of the Internet via Wi-Fi and cable, say, more than 10 devices, and constantly download something, play online games, and perform other complex tasks, then you need a more powerful router. For example, as an option, you can watch TP-LINK Archer C20i, which also supports Wi-Fi 5 GHz.

This router without problems will distribute the Internet to several devices via Wi-Fi, and via a network cable. Judging by the information on the box, it can withstand online games, file downloads, etc. But you need to understand that everything is in moderation. If you run some heavy games on several computers at the same time, then most likely it will not withstand this load. If such budget models could cope with all the tasks, then who would buy a router that costs ten or more times more.

Hello everyone. Please help. Wifi router cutting speed.
The provider delivers the Internet at a speed of 500 Mbps. And the output of 18-20 Mbps. - wifi.
I understand that you need other equipment, but would that b is a little more work to do.
On a straight line through the cable produces 550-600 Mbps, and even more.
Recently still was well distributed router 100-170 Mbps. through the air, and now it is not clear what to do.

distributed router 100-170 Mbps

interesting as it could router with 100Mb / s ports to issue higher speed of 100 Mbit / s.
changing the wifi channel and measures the speed, it is better to make a few changes on the same channel, the results - leaving the best channel and bandwidth needed to deliver 40MHz for maximum speed.

Hello, I need help / advice
In general, such a problem that when you connect the router directly to the main wire no no problems of the Internet, but as soon as I try to build another 10m wires through the mother / mother (one patch cords), the first time you connect the Internet is, but after switching off / on food (I need every day to turn on / turn off the power in the room), the Internet is not observed. We have to remove / insert the wire from the mother / mother and from the router, and at some point comes online. By the way, a new patch cord, such garbage with any graft of wires, an Internet cable is also a

P.s. even tried to build 3mya serially connected patchcords 0.25 m through the mother / mother, and everything works fine, but is not an option at all

* retgar,
There is a router or a switch where there are LEDs indicating the presence of a link? Just a bad contact, I suppose the total track about 100 meters Test patch cords, pinout, just in case. You need to check when it is not running an Internet, there is a link via cable or not. As a crutch, cutter connector pins can be cleaned from the plaque, may temporarily help. Better course to solder and heat shrink. optionon the knee.

Varick 2 - or your rotten adapter, which is not uncommon. Either the total length of cable router no longer transports if (as here also "barrel" which can suppress non-acidic because of contact points 2 and often unintelligible without winding conductors within it). By signs up against the Har-ki incoming line. Try to make a couple the barrel instead. What is the approximate distance from the TKD dip?
