Could you also try disabling the Disassociate on low acknowledgement setting under Network → Wireless → SSIDs → “Edit” on the interface → Additional settings:
Next, under Network → DHCP → Server Settings, could you confirm that the server is enabled? If it’s disabled, this could very well cause the devices to either connect/disconnect, or not connect at all:
When these disconnections occur, could you please head to WebUI → System → Maintenance → Events Log and check whether you’re able to find any logs that are related to the Wi-Fi? If you could, please send a screenshot, but blur out any sensitive data (Public IP addresses, MAC Addresses, etc)
I disabled the option you suggested. Let’s see if it works. DHCP is enabled. As for the logs, I’ll keep an eye on them now. Thanks, I’ll let you know.
Can I ask another question? I have a server connected to a Teltonika LAN port, and the server’s LAN port started making noise (a whistling sound) when the port speed was set to 1 Gbit. For now, I’ve limited it to 100 Mbit, but that’s not a good solution. With another router, this problem doesn’t occur.
Whistling sounds are definitely a first for me, never heard of that happening before, are you sure it’s not coilwhine from the power supply unit? Could you upload the video and post it here?
In your video, i can hear coil whine even on 100Mbps. When you change it to 1Gbps, it just gets louder. Your LAN card, your power supply, or something in that chain is causing a coil whine. Im sure you would get same result if you plug anything else that operates at Gbe speeds. I would check that server`s power supply. This is not normal and it could be dangerous. Also make sure you have proper grounding. You dont want your sever to get the grounding via LAN cable.
Yes, actually, you can hear it even at 100mb. Keep in mind that my phone amplifies a lot. My computer is connected to a UPS, and I recently changed it. Maybe that’s the problem. I’ll test it. Thanks.
Power supplies in grey metal casings are known to be on a cheaper side. Also, coil whine is not always dangerous. However, the tricky part is making sure it is actual coil that makes that sound. Dying capacitors, transistors and mosfets can produce sounds similar to coil whine, and thats deadly. When cheap power supply dies, it can kill everything else its attached to. Dont ask me how i know. Also, try connecting your server directly to power outlet in order to rule out UPS problem.
@trisosamu10 I don’t believe I can add anything on top of what heartless already said, all that’s left for you is to test with a different PSU, stay safe!
