    RT-AC68U one CPU pinned at 100% due to wred process

    I have 2x RT-AC68U running in a mesh. The main router appears to have CPU1 stuck at 100% usage: When I SSH in and use the top command I can see it's the wred process: This is after only 2 days of uptime (my router auto reboots every 2 days). I am running firmware 386.5_2 and I can't...

    Merlin 386.4 on RT-AC68U no space left with kernel errors every week

    As the title, I have a RT-AC68U running the latest Merlin 386.4. It's a fairly basic setup with most things disabled including uPNP (HW acceleration is enabled). About once a week I begin to have issues with the router connecting and have to reset it, sometimes physically (the 'Reboot' icon in...

    How to try and stop OpenVPN connection attempts?

    My router log is completely filled with OpenVPN connection attempts from what I assume are malicious IPs. Here's an example from this morning: Jan 6 10:34:56 ovpn-server1[1251]: 150.95.91.174:25566 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network...

    Default OpenVPN server no longer works with OpenSSL 3

    I have an RT-AC68U running Merlin 386.3_2. It's running OpenVPN with basic setup. All I did was enable it and added a user. This has always worked until now with some latest OpenVPN clients it won't connect with: 9:14 a.m. library versions: OpenSSL 3.0.0 7 sep 2021, LZO 2.10 9:14 a.m...

    Randomly unable to access hard-wired device on Mesh router

    I have 2 RT-AC68U units running latest Merlin software (386.3_2). One is the main router, and the other is a Mesh unit with WiFi backhaul. Connected to the Mesh router I have a Raspberry Pi 4 hard-wired into the ethernet port so it can gain internet access over WiFi. This device has a DHCP...

    RT-AC68U 386.2_6 - WAN_Connection: ISP's DHCP did not function properly with TekSavvy / Cogeco cable

    There are many threads about this issue already on snb, for example this one. I am only creating this new thread to indicate that specifically with Cogeco cable (resold through TekSavvy, though I doubt that matters) there is no current solution to the issue. If anyone is not familiar with this...

    RT-AC68U 386.2_6 packet loss on OpenVPN failed connection

    I have an RT-AC68U with a wired Windows box running PingPlotter (although I've confirmed this with a wired Linux box running ping directly as well). Basically at random times nefarious connections are attempted to my OpenVPN server running on the RT-AC68U. The log looks like this: Jul 23...

    RT-AC86U with 384.15 has an unknown MAC trying to connect over and over

    My general log was getting spammed with dissoc messages after migrating from 384.13 to 384.15. I commented about this problem here: 384.14_2 on AC86U | Disassociated because sending station is leaving.... The log spam looks like this: Mar 5 11:54:11 syslog: WLCEVENTD...
