Devices involved:
-
Mikrotik Router (LHG LTE6) - outdoor unit (Main Router)
Current firmware version: 6.48.4
Router OS version: 7.2rc1 (testing)
2. D-Link Dir 615 N300 router- indoor unit (acts as an Access Point)
Connection Setup details:
Mikrotik Router is connected to D-Link (Which acts as an Access point)
IP address is assigned by the main router which is Mikrotik
So, all the devices connected to the D-Link Wi-Fi will get IP address from the main router (Mikrotik)
Setup diagram: PFA
Issue description:
Problem I’m facing here is, suddenly all the devices connected to the D-Link Wi-Fi get disconnected, even the D-Link also gets disconnected from the
Mikrotik router.
Error message in the smartphone: “obtaining IP address from the DHCP server” and disconnects and not even connecting to the WIFI
Error message in the D-Link: Failed to obtain IP address from the DHCP server
Troubleshooting done to isolate the issue:
Once the Wi-Fi disconnects or the issue occurs, I connect my laptop directly to the Mikrotik router and it says “unidentified network”
Not even able to ping the device. (Mikrotik: 192.168.88.1)
In ‘stable’ and ‘long term stable’ versions I also face the same problem. So, I upgraded to the testing version and there also I’m facing the same problem.
Checked the D-Link with router mode also, facing the same issue.
Even if the link goes down due to the telecom service provider which I’m using, it should reconnect after a minute right, but it is trying to obtain the IP address from the DHCP server for more than one hour. (Only after switching off and then on, it working)- mentioned detailly in the temporary solution section.
Even tried rebooting the Mikrotik router but no use.
From the above things I confirmed that the problem is with the Mikrotik router.
Note: Bought new Router TP-Link AC1200 Archer C6 and tested the same but the issue remains.
Temporary solution:
I just switch off all the device and switch it on after one minute and it’s working fine.
Again, after certain times the problem appears, and I will repeat the same to solve the issue.
Queries:
Why did the Mikrotik router suddenly de-assign IP addresses to the devices connected to it including the Access Point(D-Link)?
Why does the problem solve only after switching it OFF and then ON?
Are there any configurations that need to be changed in the router? If yes, tell me what to do.
I’m ready to provide any information you need. My priority is to get the problem solved.
Note:
If you are suggesting a solution, please explain clearly and step by step.
I hope you guys will help me in resolving the issue.
