System Log - Wireless Log - Incorrect Hostname Displayed

[cvx01]

Hello All,

I'm having a weird issue with the wireless log I was wondering if others had seen as well.

Let's say I have a DHCP LAN reservation for 192.168.1.100 and 192.168.1.10.

Let's say 192.168.1.100 = hostname A and is wired
Let's say 192.168.1.10 = hostname B and is wireless

The wireless log will show the correct wireless MAC for hostname B but the hostname hostname A.

Example:

MAC ADDRESS OF HOSTNAME B - IP ADDRESS - HOSTNAME A

This also happens with something like 192.168.1.5 and 192.168.1.50
The hostname doesn't match the wireless MAC address.

Basically, the wireless MAC appears to always be correct, however the hostname is a complete crap shoot depending if a similar ending octet IP is used.
(192.168.1.100 & 192.168.1.10; 192.168.1.2 & 192.168.1.20; 192.168.1.3 & 192.168.1.30, etc..)

EDIT: I'm running the N66U on 3.0.0.4.372.31. This issue was present in all past FW I can recall.

Hi,

Did you assign the ip addresses and hostnames on the LAN/DHCP Server page "Manually Assigned IP around the DHCP list (Max Limit : 128)" in the router web interface? What name did you put there?

OR: What name do the devices/os have assigned?
Maybe they have wrong names assigned in there operating system...

With kind regards

I can confirm I have the same issue. From what I can tell it's not related to dynamic or static addresses but most of the time I have 1 or 3 wrong name-mac associations. It's never the same ones either so pretty sure it isn't host config related. There are some devices that show a blank name so not sure if that is causing issues with the string extraction.

To be honest I think it's always been there but I figure it's only cosmetic in the grand scheme of things.

Thanks all for the responses. Yep. I have every device IP, MAC and hostname manually assigned using the LAN/DHCP page. And the names are quite unique and device specific that it wouldn't be a mix-up at the endpoint level. One device isn't even a PC, but a wireless thermostat (Which is listed as my PC name within the Wireless Log screen). From what I've seen, normally the hostname is pulled from whatever you type on the DHCP assignment page. If no assignment, then it will use what the device advertises.

Looks like others are having this issue too. Hopefully this is fixed in an update. While it's cosmetic, its a time saver to see the correct name when attempting to troubleshoot various WiFi issues.

I too have the issue with blank names appearing, even when properly manually assigned within the LAN/DHCP page.

Thanks for the report. This is due to the pretty crappy parser that I wrote to retrieve that information from the leasefile - it will be fixed in the next release.

The issue is indeed related to cases where you have two IPs that (at a string level) seem similar, i.e. 192.168.10.10 and 192.168.10.100).
