Guys, I want to confirm that what he wrote on the forum openwrt - their firmware on the device leads to a significant drop in the network speed to 2.4GHz frequency.
At a frequency of 5 Hz this is not observed. The problem is how they communicate is not solved.

https: //forum.openwrt....tains-connection/53575

As I checked out - because it did not trust every spidtestam, each of them showing up on super bad every minute. Therefore I tested for torrent downloading speed.
So 5metrov distance between the router and I only wooden door, leeching the same torrent file with a good distribution (many seeders).

Frequency 2.4Gts injection speed 2.3MB or 18.4megabit peak.

Frequency 5Hz injection rate or 47.2megabit 5.9MB.

Done test 3 times so, and commercials. The result is the same My Net 50mb.
The drain I had a max speed on both frequencies.
Draw your own conclusions.

Vitaly Leer , i7i5i3i ,

Guys got confused in the instructions and files. Help revert to drain now stands openwrt 19.07.2.
I Archer c50 v4 ru. I would like to Taiwanese or European Proshka leave. Poke your nose pliz

kapellan133, EU TP-LINK ARCHER C50 - discussion [0.9.1 2.1 v0045.0 Build 160,318 Rel.47820n] (Post i7i5i3i # 92375015)

kapellan133 , I tried to downgrade the firmware version. helped)

i7i5i3i , Thank you tested this method. Also works.

Thank you, the following advantages will be discussed later. to roll back the file load. Next update to the latest European. Speed ​​on 2.4Gts returned to full.

Thank you, successfully passed her with Eu version. Question.
After the firmware via tftpd, I decided to flash the device with respect to the normal web interface so sure - firmware used the same, only this time with the full site. O error, does not flash.
Just does not install firmware versions below with Taiwanese site.
What to do? can we consider the firmware via tftpd full?

full is by how much? As now gives torrent?

I report if you are interested.

So, the problems at the drain did not notice, like the interface, I do not want to change for OpenWRT.

For the sake of a greater count of channels in the 5GHz I began to try other stock firmware. (And even deshmansky Mercusys AC12 keeps out of the box UNII-3, insulting hardware seems they are the same:. MT7628A + MT7612E, the last chip specification supports the entire range of 5180-5825.)

Sewn through tftpd64 (cut firmware before lecturing respected i7i5i3i, , thanks):

1. Archer_C50v4_TW_0.9.1_0.2_up_boot [191025-rel38371] - English language, the choice of language is causing the error, then through the web allows you to flash only on the RU version (the other causes error 4503), the channel is not added, even the settings are not reset, visually and functionally It was identical to my sink RU.

2. Archer_C50v4 (A50v4) _EU_0.9.1_0.1_up_boot [171129-rel59954] - English, there is no error, setting reset (and the file version RU not recover, only hands) became Hardware version: Archer C50 v4 00000001. It came the long-awaited additional channels. However, in fact eight available channels 36 through 64 in any channel width, and 132 and 136 at 40 MHz width, and 132, 136, 140 at a 20 MHz width. The channels from 149 to 165, although listed, but in fact transferred to the device on the 36th channel. Through the web allows you to flash any RU, but also managed to flash on Archer_C50v4_EU_0.9.1_0.2_up_boot version [180313-rel54477] - it is visually identical to the version of the EU 171,129.

3. Archer_C50v4_RU_0.9.1_0.1_up_boot [180508-rel41966] - a full-fledged Russian, can be updated via the web on any RU, returned Hardware version: Archer C50 v4 00000002.


Lord, tell me, please, somebody channels actually work from 149 and above? Those. I have this bug firmware or hardware issue?
Has anyone tried the Canadian firmware Archer_C50v4_CA_0.9.1_0.1_up_boot [180313-rel55577]? It is probably identical to the European of the same date, but the embarrassing release number.
And in the Spanish-speaking emulator (Argentina, Chile) have additional channels and a selection of the country, but in fact all Hispanic firmware everywhere replaced by the same EU 180313. Where to get the one from the emulator?

There is a Korean language but only their difficult nastroit.U they opposed the choice of Korea in the region and integratsiya.I 2.4 g have a choice of only 5 g n.Kanaly 149 rabotaet.Vot problem set only.

Post has been editedi7i5i3i - 14.04.20, 20:39

On the last (eu) 5 g 36- 44 only reason it was to.Do and 149y.

Thank you! Apparently the same firmware work differently on different routers, even if they v4 (I have version 4.2).
Here's what this Korean in my, in 2.4 you can choose standard, but only "auto" 5 channel.

karat831 ,
Sorry for the late reply. Mean frequency of 2.4 my 45megabit outputs, as well as frequency 5d. I forgot to specify. 45MB is the ceiling of my network

DjMaxx, It is necessary in the window above where the empty region selection point to note top - Korea, bottom - the other, and then the channels will dostupny.Vybor why the region is cleared after turning off the router.

i7i5i3i, Really I did not notice. Really works, total available UNII-1 and UNII-3. It is necessary to teach the Korean ... :)) or tomorrow we will try to cut the Canadian firmware - there are at least English.
But in general it is some dancing with a tambourine: 36-64 in the European (8 channels) + narrow 132-140 (3), on the Korean 36-48 (4) + 149-161 (4) + 165. In a narrow v1 was It is humanly: 12 + 4 narrow wide.

Archer C50 v5 v4 looks like the same thing, because. after installing the firmware from v4 to v5 it works equally well except for the power indicator.
Reverting to the drain Archer C50 v5 (us) on the TFTPAvailable channels 2.4g - (1-11) and 5g - (36-44,149-161)

For people like me who are interested to try the stock firmware. A little digging on the issue. By programming I do not have any professional relationship, so probably will look naive, but it is as it is. : Sveta:

So, as I wrote earlier, I have Archer C50 (RU) v4.2, out of the box firmware 0.9.1 0.2 v009b.0 Build 181,213 Rel.55156n (5255). The drain firmware does not suit me only the number of available channels in the 5 GHz (36, 40, 44, 48). (Although even Mercusys AC12 v1 there is 149-165, but that I have handed back because of the terrible "child" interface.)

1. Based onRF Government Decree of 12.10.2004 N 539 (ed. Of 22.12.2018) "On the procedure for registration of radio electronic facilities and high frequency devices"indoor permitted frequencies 5150 - 5350 MHz and 5650 - 5850 MHz (channel 36, 40, 44, 48, 52, 56, 60, 64, 132, 136, 140, 149, 153, 157, 161, 165). Learn more about channels and bandsfor example here.

2. Archer C50 v4 is built onbunch chips MT7628A + MT7612E. The last kind of just responsible for the 5 GHz and, judging by thespecificationsIt operates in the range 5180 - 5825 MHz.
Looking ahead, confirm that Archer actually works and 36 and 165 in the channel.

3. searched all regional tp-link sites to search firmware. I discovered two features:
• European firmware 180313 is a "basic" in most cases. Or its more recent "Europeans" have replaced almost all regional firmware (including Spanish-speaking Latin American countries, which, judging by the emulator was extended channel selection and the choice of the country). : Girl_cray:
• Emulators do not always convey the reality (or they are made at previous assemblies, or it depends on the device version 4.1 / 4.2 ...?)

4. A total of 10 runoff downloaded firmware (including one for the United States to v5 - thanks i7i5i3i, It works, but ... there I have access to the same channels as in RU).

ATTENTION! Despite what is written below I earned, I can not guarantee that it will work for you, or not at all "okirpichit" device !!! You decide whether or not to experiment.

5. According to the instructionsfrom heredownloadedCygwin(Set by default, I put the firmware in C: \ cygwin64 \ home \% user%, the same gets results)
ViaHex Editor NeoBy examining the previously posted here firmware for tftp, I came to the conclusion that not enough just to cut the 512 bytes, and the need to add more blank lines at the beginning. Therefore, I use the command format for v5:


Stock (from the manufacturer),only for the web-interface!
Clipped (in Cygwin),only tftp!

6. Next to stitch at a time through thetftpd64(I have a 64-bit operating system, run the tftp from the administrator, firmware renamed in tp_recovery.bin, I put one in the program folder) oninstructions.

After each firmware trying to upgrade through the web-interface of all the uncircumcised firmware (except Russian) - 4503 is almost always a mistake, except for the transition
EU_0.9.1_0.1 [171129-rel59954] _tp_recovery ->EU_0.9.1_0.2_up_boot [180313-rel54477] ->RU_0.9.1_0.1_up_boot [180508-rel41966] ->RU_0.9.1_0.2_up_boot [181213-rel55156]
- with the hardware version remained Archer C50 v4 00000001 (although EU_171129 was 00000002, but what does - do not understand).




7. Results:

The 2.4 GHz in all firmwares I use all the channels 1 through 13 (even in v5 for the US, which is strange) but the Vietnamese firmware behold it if the United States selected region - really only 1-11 channels.
And even noticed that in all firmwares I have the same value at the end of the version in brackets: ... (5255) - has not yet realized that means.

The first group of firmware.
They are the most boring: only available 36, 40, 44 and 48 channels (although only in the emulator v5_US "auto" - in fact there is a choice).

Summing up:
Router hardware is able to operate over the whole range 5180 - 5825 MHz. ;)
Firmware for Korean and Vietnamese support UNII-1 and UNII-3 (8 channels + 1 channel at 20 MHz). All these channels are permitted in the Russian Federation.
Firmware for Europe (only version 180313), it is the same for Canada, supports UNII-1 and UNII-2 (8 channels), partly UNII-2 the ext. (3 narrow channel). UNII-3 support declared but not working. All declared channels allowed in Russia.

I'd like to ask for tp-link to add the last Russian firmware choice permitted in all RF channels (I think it is at 5 minutes of work), but I suspect that will be sent to a known route. : Blush:

Hello. I'm in the topic of routers and Internet connections kettle, so overdue issues.
I want to change my router tl-wr841n on this issue, as appropriate? If the internet speed is determined by the service provider (ISP), how the change will affect the router's internet speed or even to work the Internet? On speedtest.net determined speed of the Internet as a download of about 50 Mbit / s, and also loading of about 50 Mbit / s, then when you change the router, obviously, the Internet speed will not change? Then it makes no sense to change the router to a more powerful, if the operator does not provide the proper speed of the Internet? I hope you understand what I mean, thanks in advance.

Ya diesel ,
Tariff 50? Get 50.
Tariff 100? Get 100.
C50 will 5GHz range. It is relatively clear. But less punchy. At 5GHz speed will be slightly higher, what is 2.4, but is no longer the provider rates.

Hello everybody. In V4 me. I tried all local codes, including exotic. The drain, OpenWRT, Taiwanese effect is the same. 5G network visible, but does not connect. IPhones say that the password is incorrect, IPTV set-top box - that the network can not be found. Then people complain that 5G falls off, I did she simply is not available for connection. Feeds changed. As a result sit 2.4 with occasional blade the IP-chambers, the outlets. For all customers over 20.
