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.

* STSOrc,
A small addition - since sewing through tftp, then sew immediately openwrt, sewn stitching in its nametftp-recovery
As well as the firmware file for tftp can be made from the image to openwrtsysupgrade adding ahead EEPROM 131072 bytes of zeros.
When the firmware via tftp loader passes 131,072 bytes from the beginning of the file.
All of the above applies to models 840 v4 and v5.

Everything is exactly as you say. Maybe there is a link to DDR 128MB?
Otherwise I will return the seller and order from Ksyomi R3G

There are 840 V2, which put OpenWRT or DD-WRT or Gargoyle, interests the stability for the dumps on Wi Fi when the files jump suffer, and it is desirable as in the last run. You can enable the bridge mode. Internet transmission via cable to hospital, and signal distribution through antennas}, but if the choice, still more important stability.
