Must learn to read. Under different versions of the iron between the versions.

I can not throw Wan on any LAN! o.O almost no experience, did everything in 1 time.
with Open wrt failed, and fled into a more understandable dd wrt try and adjust it in 3 ways, which is below, wan 1 or 4 lan port, but PPPoe session does not want to be connected and the IP from the ISP does not come.
. Worried that if the console port of the command changes in the GUI does not display changes made! it is not clear chipped the port or not.
By default, all I have is like this screenshot:
Pliz throw off the screenshot at right as it should be if the throw on the WAN port 4 for example.

I try these:

The second option, reassigning the WAN port on the console LAN4
Open the administrative panel of the router and enter the Code:
nvram set vlan0ports = "1 2 3 5 *"
nvram set vlan1ports = "0 4 5"
nvram commit
reboot (reset in the header is not written rolls!)

Let's say we want to make a wan port of the first LAN port
Daw "Port W-1" was filmed and put on the "Port W-0".
Daw "Port 4-0" was filmed and put on the "Port 4-1"

Let's say we want to make a wan port of the first LAN port
switch reg w 70 ffff4867
switch reg w 44 2001
press the button "Save Starup"
(I swear to switch reg)

Open the console router
Let's say we want to make a wan port of the first LAN port
nvram set vlan0ports = "2 3 4 5 *"
nvram set vlan1ports = "0 1 5"
nvram commit

Good afternoon, there was a problem, routert restarts under load, for example when trying to download a game from the Google pleya or check the speed.
It began with a conflict router and curling irons, but now the router is in conflict with everything.
Before that could pull a bunch of devices with incredible speed, what can be done?
Help me please!

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: (440)
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 primary client is
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.

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.
