Tp-link tl-wr940n v4 problems for install

@mk24

modem by simply going from a LAN PC to 192.168.1.254. Anything outside of 192.168.0.X will be routed to the WAN port automatically.

Thank you for the answer.

If I understand correctly I should have no problem accessing my box by typing 192.168.1.254 since it is on the LAN port.

Except it doesn't work. I have a following error: DNS_PROBE_FINISHED_NXDOMAIN

@mk24

DHCP list will only show devices which used dhcp from the router. Those configured with a static IP will not be in the list. You can see the IP and MAC of everything that has connected to the router using arp.

What is ARP? I'm not yet top of the line yet.

@mk24

Control such as having a list of allowed and disallowed websites is possible with OpenWrt, but takes more memory than your device has. Time based all or nothing rules like turning off the wifi or Internet access entirely at night is possible.

As a parental control I'm mainly looking for something like "this device can't connect to the internet from this time to that time or that day".

Is there an android APP to control a router from a phone?

This is an error on your part. Ensure that you're properly typing the IP address. For some reason, your client saw that entry as a bad domain name.

Have you seen this section in the Firewall section of the LuCI web GUI?

Just browse to the router using your browser. You should see this page easily on a phone.

(Again, this infomration is included in the manual, and by searching the forums: Parental Control for time restrictions not working with "reject")

Thank you but I don't have that under my firewall menu. (unless I'm blind)

I think it's a mistake on my part but I can't find the solution because on the old firemware it was the dns that didn't work.

I can't be good at it.

Address Resolution Protocol

L’Address Resolution Protocol (ARP, protocole de résolution d’adresse) est un protocole utilisé pour traduire une adresse de protocole de couche réseau (typiquement une adresse IPv4) en une adresse de protocole de couche de liaison (typiquement une adresse MAC). Il se situe à l’interface entre la couche réseau (couche 3 du modèle OSI) et la couche de liaison (couche 2 du modèle OSI). Il a été défini dans la RFC 826 : An Ethernet Address Resolution Protocol. Le protocole ARP est nécessaire au ...

Thank you but I don't understand any more I'm going to read what you gave me you never know.

S'il vous plaît, prenez un moment pour parcourir l'appareil vous-même.

It seems as if you're not willing to take time to simply browse the web page.

You may be...

And what about when when you actually CREATE A RULE!?!?!?!?!?!?

(Again this information is in the manual, and available by searching the forums.)

@MaC_ToC

What is ARP?

You asked what ARP is. I sent you a WIki entry (in French and English) - and the manual to use the arp command. The DHCP server in OpenWrt only knows the IPs it issued. As @mk24 said, to see all other IPs:

@mk24

You can see the IP and MAC of everything that has connected to the router using arp.

believe me that's what I do, but I'm not a pro and therefore what seems logical to you is not logical to me. I looked at the links you gave me but I didn't see all this.

Sorry again to bother you.

I won't bother you again.

Thank you. Thank you.

@MaC_ToC

I learned the same way, via looking at the manual. I never implied anything requires professional skill. It does require basic understanding of networking and web browsing, though.

@MaC_ToC

I looked at the links you gave me but I didn't see all this.

I would simply advise you to browse more:

https://openwrt.org/docs/guide-user/firewall/fw3_configurations/fw3_parent_controls

Linux network interfaces

Also, FYI, the command arp command has been deprecated for ip -4 neigh. (see network link above).

@MaC_ToC

I won't bother you again.

Thank you. Thank you.

J'ai eu le plaisir de vous aider. Toujours se sentir libre de se renseigner à nouveau.

Hi! Could somebody please help me with entering recovery mode for this device so I could install an openwrt binary on it via TFTP? So far, I tried:

• holding down reset button on startup for 4 seconds,
• holding down factory reset button on startup for 4 seconds.
  The lights on router still don't start flashing as they should. So far, I managed to enter recovery mode easily on Linksys and Asus routers, but this one oposes a problem...
  Thanks!

@gasperataj, welcome to the community!

• You may wish to start a new htread in the future
• It sounds you are confusing OEM flash mode and OpenWrt Recovery mode
• Have you seen this? - https://openwrt.org/toh/tp-link/tl-wr940n#installation

[mk24]

I don't think the lights flash. You need to have your TFTP server ready to go on 192.168.0.66 as the router comes up, then it should download the file and flash it.

• Connect an unmanaged switch between the router and PC so the PC doesn't see the Ethernet carrier drop and reconfigure its port.
• Do not have the PC connected to any other network, wired or wireless.
• Shut down any firewalls on the PC. The default Windows Firewall will prevent TFTP server from working.
