TL-WR840N V5 Can't Access the Router

look here fix

Wrong. WDS/Repeater/Range Extender are only different ways to implement increasing the range of the WiFi. OpenWrt is a firmware for full-functionality routing, and increasing the WiFi range is only a part of what it does.

Anyway, for you to use the router in your network, that depends on how you get internet in the first place. If you get it on RJ11 (phone socket) or similar (commonly used with ADSL), then you will have to keep your ISP router in place and connect it to your OPenWrt router. there are different ways to configure it:
1- ISP LAN (with current configuration) <---> OpenWrt WAN (set as DHCP client)
2- ISP LAN (in bridge mode) <---> OpenWrt WAN (set as PPPoE)
3- ISP LAN <---> OpenWrt LAN (here the OpenWrt router works as switch only
The following link shows more details

If on the other hand you have internet coming directly on Ethernet cable ending with RJ45, then you would completely remove the ISP router and connect OpenWrt router directly.

I didn't understand what you were saying about IP. Are you talking about WAN-side IP or local IP? Also it would help if you give more details about your ISP router and what kind of internet connection do you have

What i mean is as Market Router like :
ISP Modem > Router WAN then Router WAN > PC Lan
and about IP what i say is my ISP lock the Connection from MAC Address, so if i'm use ISP > Router > PC i must clone the mac address of my ISP Modem to get internet access.
hopefully you understand what i write.. :smiley:

You mean ISP Modem > Router WAN then Router LAN to PL LAN. Yes, you can! These are options 1 and 2 in my message.

Cloning the MAC address is possible. Check



Yeah i already Try it, but on LAN still no Connection.
I still no idea why...
Take a look at this pict

On WAN Ethernet Port i must add Mac ISP to get internet access. then LAN Port will Connect into my PC
FYI i just using 2 Devices.
1 my ISP Modem ( No Wifi Included )
2. My TP Link as Router.

This interface seems to be from TP-Link stock firmware? Or is that an old version of OpenWrt?

Does the TP-link router have internet connection or not?
The MAC address you cloned to the WAN port is the MAC address of the PC, right? Did you change the MAC address of your PC to something else?

  • This interface seems to be from TP-Link stock firmware? Or is that an old version of OpenWrt?

Yes it's from TP-Link Stock firmware.

  • Does the TP-link router have internet connection or not?

If i'm using Stock Firmware, connection avaiable.
but when i change it to openwrt, No Internet access.

  • The MAC address you cloned to the WAN port is the MAC address of the PC, right? Did you change the MAC address of your PC to something else?

The MAC Address im cloned to the wan port is from ISP Modem. already try to Override MAC Address into WAN Interface, still can't get connection.

@jeff He was saying that he wants to achieve the same in OpenWrt

Finally i can connect to internet with openwrt. After some factory reset and other things do. A simple question why after do reboot on luci i lost my current configuration ? And I have other question about wifi. But maybe i will create with another new thread or maybe just here ?

My first guess on a device with 4 MB of flash is that you don't have a functional overlay.

What do

mount

and

df -h

show?

So it means i cannot reboot my router right ?

The router has very limited Flash memory. If your case is that there is no space to save configuration (and I imagine that your image is so stripped that there are no packages you can remove to make space), then you should avoid rebooting. You could have the configuration commands and settings saved in a text file on your PC so that you can easily make the configuration if you reboot.

I think so. But it to hard if everytime my power home off, i must setting it over again, lol so Can you PM me some router with 8mb flash arround 10 - 15$ maybe ? Cause in my region its soo expensive didnt need too much just need it for normall routers, and need it for vpn mini server, 300mbps link speed, and dual bands. 100mb ethernet its okay, even my isp only 30mb lol @@

See What's your favourite cheap LEDE/OpenWrt device? for some inspiration.

Look what's available used on ebay or the likes, then cross check that with the discussion @tmomas mentioned above and also with https://openwrt.org/toh/views/toh_available_864

I Guess i will go for wr1043nd v2 Looks Cool and the features as well as i needed.... :smile:

i bricked my wr840n v5 and i flashed @schara and now i can connect my router through puddy > ssh . how can i revart to my stock firmwere can u help me plz???? @jeff

  • Do not attempt TFTP recovery.
  • The flash over stock uses a sysupgrade image, thus you can probably flash the stock firmware from OpenWrt using sysupgrade. First use binwalk on a Linux PC to compare the properties of the two files.
