Hi all,
I have a GL-MT6000 that is intermittently losing Internet connection. I have a Ring home alarm system that notifies me when the system goes offline. I have the glinet app on my cell, and when this occurs, I am unable to wirelessly attach to the router. The app gui states I need to connect to the wireless network to gain access. After several minutes, I can connect to my home wifi network, but initial indicator say wifi is connected, but without Internet. After a few more minutes, I can gain access to the router from the app, and exported the logs. I intend to connect an Ethernet cable, so if/when this occurs again, I can get better insight as to what is occurring.
This is a fairly new router, and I recently installed ovpnclient. In the short time I used the router before ovpnclient was installed, I don't believe this issue occurred, but I can't rule that out.
WAN Protocol DHCP
GL.iNet GL-MT6000
OpenWrt Version OpenWrt21.02-SNAPSHOT r15812+1082-46b6ee7ffc
Kernel Version 5.4.238
My Ring home alarm indicated:
|offline |07:01 est|
|restored |07:09 est|
In looking at the system.log, I see the first timestamp is "Sat Jan 18 07:05:48 2025" which is subsequent to the initial event that seemingly caused the issue. Again, Ring went offline at ~07:01 est. Are there specific keywords that I can search for in system.log (or other applicable logs) to help determine what occurred?
The system.log shows these events for ovpnclient. These events are ~6 minutes after when initial outage occurred.
Sat Jan 18 07:08:38 2025 daemon.notice ovpnclient[11161]: [usxxxx.nordvpn.com] Inactivity timeout (--ping-restart), restarting
Sat Jan 18 07:08:38 2025 daemon.notice ovpnclient[11161]: Closing TUN/TAP interface
Sat Jan 18 07:08:38 2025 daemon.notice ovpnclient[11161]: net_addr_v4_del: 10.100.0.2 dev ovpnclient
I can post entire logread.tar file if that doesn't present any security issues. I appreciate any assistance..
Hi..initially, I tried WireGuard protocol for NordVPN, but after configuring connection, I was only able to see 6-8 vpn servers (all geographically distant). I contacted NordVPN support, and they told me WireGuard is not supported for routers. They said standalone Linux install is supported, but Linux embedded on this router is not. They recommended OpenVPN.
Are you seeing telltale signs that this vpn protocol connection is the cause?
Can't tell for sure because I don't use Nord at all.
But the OVPN tells us, that an timeout is happening and the VPN will restart - which will cause connection drop.
So the question is: Is the ISP connection failing and then the VPN fails or vice versa?
Could you please post the log entries that correspond to the connection failure?
I did reconfigure the vpn to use WireGuard and now see more vpn servers, but they are all geographically distant (Seattle). I am running now using WireGuard and can monitor to see if that resolves the issue. If I can go several days without a disconnect, I can begin to feel that was the fix.
The logs I was able to capture are subsequent to the disconnect at ~07:01, and begin at ~07:05. Are there any security concerns with uploading the tar file with full logs?
As of this time, switching from ovpn to WireGuard appears to have stabilized the intermittent disconnect issue with Internet However, it has broken my ability to use wifi calling (ATT). I get fast busy when trying to make outbound calls. If I disable wifi on my cellular device, or stop vpn on the MT6000 I am able to make OB calls. This appears to only become a problem after switching to WireGuard. Any ideas if this is specific to WireGuard in general, or if this is a problem with NordVPN?
In working with NordVPN support, again they tell me that WireGuard for embedded Linux on MT6000 is not supported, and they (again) advise to use ovpn. Instead of using the configuration procedure outlined in the GLinet document for installing the OpenVPN client on MT6000, they directed me to the process outlined in their documentation (GL.iNet setup with NordVPN – Live Chat, VPN Setup, Troubleshooting | NordVPN Customer Support). Their guess is that the disconnect was caused by excessive load on the the vpn server I was using. They provided a specific server to connect to, and provided the associated ovpn configuration file. Reverting back to ovpn resolved the wifi calling issue, and so far no intermittent Internet disconnects.
