How to prevent RT-N66U to show information about itself?

RT-N66U with Asus Merlin 26b

The router shows login prompt providing information that identifies it as RT-N66U. Due to security reasons I would like to prevent this. Any ideas how to manage this issue?

You would have to modify the source code for this.

Try "Advanced Settings/LAN/LAN IP/Device Name"

Try "Advanced Settings/LAN/LAN IP/Device Name"

This is not the case. The device name is different.

Thank you Merlin! I suspected that may be the string "RT=N66U" is "hard coded" in the source. Could you consider changing this in future releases? This is not a big issue when the router is accessed from the LAN side, but if the same information is provided from WAN side this will be a matter of concern.

A quick glance hasn't revealed where the string was coming for, I would have to look deeper in the code (I never really studied that section of the httpd code). My guess is that it's simply based on the modelid, but I would need to find it to be able to confirm this.

Thank you Merlin for your efforts! Just to add a similar issue - the nmap scan from LAN side identifies router as www.asusnetwork.net, which seems to be of same security concern.

I guess if you have upnp enabled it would be of the same concern. Anyone can see the device in netowrk properties.

And then if someone on the lan was smart enough to plug the gateway mac into a mac search tool they could also see that it is an asus brand?

Now what?

Someone could already tell you that the router is an Asus by its MAC address. Therefore having the hostname also refer to it as an Asus router doesn't lower your security in any way. If someone has access to your LAN, a simple ping to the router would tell them the MAC address, which would then show them it's an Asus.

Just like I can tell you that my ISP's fronting router is a Cisco by the MAC address of packets I get from them.
