My flint 2 has been working fine for months, until today. Basically what happens is that the WAN port stops having connectivity. The only change made in the last week was to upgrade to version 4.6.4.
Things I´ve tried in the meanwhile:
Reboot the router and also to reboot the network operator router. Things work for a few minutes (around 10 min) then the issue happens again
Change cables, change wan port, use multi-wan port. Same issue
Full reset. Worked for 10 min, then the same issue happens
Downgrade to 4.6.2, same thing, worked for a few minutes and then stops working
I've sent an email through glinet contact page, still waiting for answer. Nevertheless, I will leave the issue here in case someone has any ideas on what to do and gets to this first.
What I mean is that I've changed to WAN port 2, same issue and then I tried 2 cables connected on both ports connected to the same router in failover mode, and both ports were failing.
The upstream router is from Vodafone Germany product number is TG3442DE, unbranded, not sure who is the maker.
I don't have any other router to try.
What happened after that was that I connected all my ethernet devices directly to the upstream router since I needed internet. A few moments later Flint 2 came back to life and fixed the light.
I then connected the devices one by one to Flint just to see if the problem came back and it didn't.
It is now working as it should, however, I still don't know what happened and I cannot be sure it won't happen again. I'm really worried about this since I travel a lot and I need to always have remote access.
If you have a switch you can try to put in between.
You can use repeater, connect Flint 2 to your home router as failover. If Ethernet breaks it could use repeater as fail over. As repeater get a different IP so you need to do another port foward. So it will be a 2nd vpn profile. If your vpn fails you need to change to the 2nd vpn profile.
For the repeater pls use fixed IP so that it will not change, causing your port forward fails.
I have no idea if you connect both WAN ports to your home router could cause problems. But I suggest that you only connect one. Just use repeater as failover.
Ok, I don't have the extra equipment now to implement this failover, but it is something I can get.
Nevertheless, the nominal solution with just the operator router and the flint2 connected through the wan cable should work without any issue, this is a basic straightforward configuration.
