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.

Connected Inet from Kyivstar. Router offered at a cheap price. I took. It turned out the catch is that there is firmware from your ISP.

The question is whether it is possible to flash the firmware to an earlier version?

firmware on the router
3.16.9 Build 160,829 Rel.55894n



The newest firmware on the office site
TL-WR840N (EU) _V2_160406

and for FP region, and on the router written RU region

Periodically release firmware local provider under certain requirements.
Such firmware distributed by the provider and not laid out in the official website.

Regional firmware into account legal and technical features of the countries for which they are designed.
In most cases, the designation of the region's particular version of the iron can be neglected.

I have a router from Kyivstar, the problem is that listening to internet radio, and it turns off after a few minutes. used to be a d-link such problems was not, tell me who knows what is the reason

If you prefer, you can, but there is a nuance.
For example, if the device is sewn TL-WR840N (EU) _V2_160406, the downgrade without additional dances with a tambourine, will not work, as on ofsayte hanging a warning (The EU firmware was specialized for CE certificating and can not be downgraded to other version) .
And what kind of firmware for requests Kyivstar gash - I do not know.

If your ISP uses dual access (PPPoE, PPTP, L2TP), it can take advantage ofthis instruction.
In the future, specify the provider, the type of connection and the site to which there is no access.

how to roll with the European firmware at home?

SwingingTFTP-serverand firmware without buta (v2 to see the links below for other versions are seeking their own).
  • Right-clicking on the Local Area Connection Properties and vyberaem ->Internet Protocol version 4 ->Use the following IP address, and ask:
  • IP address - 192.168.0.66 with a subnet mask - 255.255.255.0
  • Take the firmware without buta, rename it wr840nv [x] _tp_recovery.bin (where [x] - major version of iron, ie v2.x - Specify a namewr840nv2_tp_recovery.bin) And copy to folderTFTP-server
  • Start the TFTP-server administrator.
  • In the Current directory (the current location), choose the folder where we have a TFTP-server and firmware.
  • In the Server interface (server interface) computer specify the IP, ie 192.168.0.66.
  • On the router hold the WPS / Reset button for about 15 seconds (WPS LED should light goes on TFTP firmware download).
  • After rebooting, can be rolled forwardany firmware(Do not forget to return the dynamic obtain IP addresses on the computer).

I will say one thing. This routre good only for domestic use, in which the network nahotyatsya laptop (wi-fi) and telephone (wi-fi). If something more, then the router will not withstand the load and falls off in Wi-Fi (2 TV + 2 = 5 minutes Nout and falls off wi-fi alone -. All works).
Lan at the same time - works fine. Something like this.

My conclusion. This router only for the student.
