If I recall correctly, guest Wi-Fi should not be able to connect to LAN hosts. However, after Flash the firmware in AX4200Q, when connected to guest Wi-Fi, it can connect to LAN hosts. Is this a bug?

Guest Network:
Enabled (2.4GHz Only)
Encryption:
WPA3/WPA2 SAE/PSK

Fast Roaming:
Disabled
Broadcast SSID:
Enabled
Wireless Client Isolation:
Enabled

wireguard enabled as server.

okay, thank you!

Certainly sounds like a regression, let me look into that

I have PM'd you a fix.
If I haven't heard back in a week I'll push it out anyway, but it would be great to get a verification, if you have the time and are able to assist.

Thank you

Hi Lantis, thank you for your great work.

I did a clean install of 2026-01-28 build on GL-MT6000.
BWmon is still buggy for me, it loses data so that the usage appears 0.000 for most (but not all) past hours. I described it previously in a post in Gargoyle 1.15.x OpenWrt 24.10 beta - 2025-08-03.

Looks like it's indeed caused by the firewall getting torn down like you said in the old thread. I got this in syslog: Am I the only one having this problem?

I was having very similar problem with all downloads shown as zeroes (see above in this thread), but I upgraded preserving settings.
I was not able to find time and flash the new version without preserving settings yet.

Alright so people who are experiencing a lot of zeroed out bandwidth data, what IP lease time do you receive from your upstream?

Sun Feb 15 09:52:41 2026 daemon.notice netifd: wan (6535): udhcpc: lease of **.**.19.188 obtained from **.**.192.27, lease time 7200

I think this is in seconds, so that's 2 hours.
Leases get renewed at half the lease time, so your WAN interface is going to bounce every hour.
Bandwidth data is only backed up every 4 hours...

So we've got a problem here. I'm hoping that both of you are having similarly short lease times.

I think I know of a way to persist the data but I'll need to experiment with it.

Where can I get this information on router if I'm still on version 1.15.x_20250331?
Logread plugin is installed and it shows records for the last 20 hours right now.
However, there is nothing containing 'netifd', 'lease' or 'wan' in the system log right now.
Should I re-connect to ISP to get this info in system log?

P.S I'm on static external IP.

FWIW, I implemented a temporary dirty hack to run bw_backup every 10 minutes instead of 4 hrs and it helps - no more zero-hours.

Hi All,

Just want to mentioned using this released that when I enabled bandwidth monitoring, My internet connection is experiencing packet loss of around 40%-33% after 2-3 days, and it's not showing graph on the router gui.

To enable graph again, I manually run this command "/usr/lib/gargoyle/restart_firewall.sh" and all graph is showing and internet is back to normal, but after 2 days I will do it again.

Just want to check if anyone is experiencing this issue?

Thanks
