A variety of laptops,tv,phones etc.. are all posting this:

Oct 27 12:21:52 dnsmasq-dhcp[449]: DHCPREQUEST(br0) 192.168.1.86 <mac>
Oct 27 12:21:52 dnsmasq-dhcp[449]: DHCPACK(br0) 192.168.1.86 <mac> <name>
Oct 27 12:21:52 dnsmasq-dhcp[449]: not giving name localhost to the DHCP lease of 192.168.1.3 because the name exists in /etc/hosts with address 127.0.0.1

Some are wireless and some are wired. The devices connect to the internet. Anyone know whats up here? I saw another post but it was related to a samsung tv. This is for my entire network.

The localhost request comes from a buggy Samsung TV. Create a DHCP static lease for that TV, and give it a valid hostname. That way it will get used by the TV when it obtains its DHCP lease.

So, I do have a samsung TV. I created a static IP for it. I also renamed all my devices in the network map to something other than their default names but I still get a the same localhost issue. This is happening on both bands as well as my ethernet ports.

Name it on the DHCP lease page, not on the networkmap. Networkmap is only a description for the router's webui only.

Thank you sir! that was my problem.. wasn't editing from the DHCP lease page.

Hi RMerlin, tried your guided steps and I gave a valid hostname "SamsungSmartTV" and tied to a static lease, and all these were done on the DHCP lease page. The error message is still happening. Anything that I have missed?

Post the exact syslog error message.

It's happening couple of times an hour. Appreciate your help!

@Dellboy
Are you using RMerlin's firmware? I also had this on my RT-AC87U, but after installing his firmware it was gone after add it under static lease.
Right now i use RT-AC88U and have the same "error message" as you have. But I don't use RMerlin yet on my new RT-AC88U

Double check the MAC address, and that you properly entered the other information (try a different IP to confirm it).

 

[Dellboy]

Thanks CiscoX and RMerlin, let me reset everything and try again. Just to confirm, the chosen static IP must be outside of the DHCP lease range?

Also, this work-around cannot be done on the stock Asus firmware?

Thanks for all your help!

A DHCP static lease is Asus speak for IP Address Reservation. You can use an Ip Address within your DHCP pool (DHCP lease range).

Might consider asking for a wireshark trace to see what the requesting MAC address is...

Hi, on stock firmware I do also have the same problem like you have. I have now installed RMerlin's firmware and the error message is gone after add the TV to the IP Reservation and gave it another name
