OpenVrt is in the cap, Dvvrt last betahere.

ddwrt flashed. But how to remove the isolation ports LAN? Do not go ping mezhu ports, I think something with VLAN. Write how to remove it through telnan.

Please tell me which firmware is better to flash in order to make a repeater out of the router? Openwrt or dd wrt? And which is easier to set up?



Rep: (360)
And which is easier to set up?

Openwrt (on LEDEinstalled for the first timeAfter the drain, the client does not go out! ).
You scan a network - you are connected by the client.
IP assign different from the main router.
That is, the 192.168.1.1 primary client is 192.168.0.1.
Without doing so there will be no distribution.
Create an access point.
It is advisable to put 14.07 or 15.05 version. In 05/15/1 wifi falls off sometimes.

Thank you very much! I will try.

I got 841 v8 at the start of the light of all the indicators and only the Power is on
The recovery mode is not included (depending on the firmware in the early ones there is no this function)
On UART falls outKernel panic - not syncing: No init found .
Treatment - watching the power-on / off log until it starts.
We sew the latest firmware from the boot loader.
WDS mode on standard issued (rate 50Mb) 25/18
The same WDS (setting explained above) on OpenWrt - 50/50
On the default firmware, you can get an Internet connection with WDS over cable, you can only manually register the IP in the network computer
WiFi is okay

Help is needed. I have this device now, before it was wr740n. Sobssno changed the router due to the fact that there were large packet losses (70-90%). In the new wr841 v11.1 the same problem. Firmware last dd-wrt. Is it a marriage or is there some other reason?
PS directly without a router no losses.
PPS if you ping 32 bytes, then there are practically no losses, and if 1000 each appear. BUT it's not the number of bytes, I really noticeably cut speed.

Rep: (360)
* Mr.Fodex,
Logically speaking, 2 routers are the same problem.
Treatment - change provider.



Rep: (4)
Herzz @ 07/15/2016, 20:52*
Treatment - change provider.

Without a router, everything is ok. even 10,000 bytes



Rep: (93)
also logically - firmware (and the V11 itself is questionable)
p.s. return to 740 with a different firmware and (or) change the provider (already advised)

Hello everyone, there is a tp link w841n ver. 8.4, stopped opening many sites. Who can tell me how to cure?



Rep: (360)
stopped opening many sites

And how does the router to the problem?



Rep: (1)
Tell my friends, I killed the router, when I decided to return from dd wrt to tp link firmware, now I can’t get to the web of the router, what can I do?

Something does not work so the client connects to any point of the wifi. The password must be entered somewhere (well, to the selected point, the client)?
I wired up yesterday at open-vrt and tried everything, it does not go in any way (and I look at the screenshots in your Russian locale, in my latest version, "language selection" is only a car, and English remains listed)
On dd-vrt also tried to connect to the client, and also fails
This is what they advised me to do on dd-vrtDD-WRT - alternative firmware (Post stp101 # 50724978)

Rep: (655)
* Herzz,
With DHCP, no action is needed (in the sense that my point gives out or takes it from the main point?)
Well, the IP also does not change, at my point?



Rep: (360)
* Rostikzh,
The only thing that changed the IP on OpenWrt is different from the base.
That it would be possible to enter both the database and the client.
base 192.168.1.1 - openWrt 192.168.0.1 of the type so

Posted on 07/17/2016, 16:34:

With DHCP, no action is required

Except shown nothing changed. If the database is configured with a static IP on OpenWrt, the mode for static has changed.

Rep: (655)
* Herzz,
By the way, on my v8 router also after a while, after turning on the router turns off, and all the lights start flashing at the same time, except for the network (it is constantly shining), the common TP-Link power supply unit from the other router is being treated. I put more powerful blocks. It is necessary to acquire either a worker TP-Linkovsky, well, or who will share the scheme from this router? (exactly the part where the interchange on the power supply is drawn is of interest.)
This happened after the lightning discharge, the entrance van port was cut down and the block was burnt, so I wonder what other units are not satisfied with it, what it lacks, voltage, amperage, or what level of pulsations ?!
Share who, with me a huge thank you

The second router (740n) from where it took the block, works equally well on both blocks! (I can't change them)

Good day!
I updated the firmware, did not change the settings, periodically turned off wi-fi on the android.
TL-WR841N, it was TL-WR841N_V9_140625, it became TL-WR841N_V9_150331.
Can you somehow overcome it?
Thank you in advance.
