Hi,
Just received the Opal router GL-SFT1200. This is my second gl inet router exhibiting the exact same problem. My first was the older Slate 750ext
Here is the issue: When I connect the Opal to a 2.4 ghz access point to provide internet backhaul and connect my client devices to either the 2 or 5 GHz Opal ap, any traffic (browsing etc) will cause the Opal to drop the repeater side connection. The light goes from white to slow flashing "blue" (which really looks like a dim white!) And if I'm logged into the admin panel I see an error that the Opal has lost internet. Waiting a few mins, the connection reestablished, only for more traffic to cause the issue to repeat.
If I reverse the "stream" and connect the Opal to a 5ghz internet wifi backhaul and my client to the 2.4ghz Opal ap, everything works fine, so it doesn't appear to be a 2.4 GHz radio problem, but strictly a repeater problem when using 2.4 as the internet link. (For these tests, I control all wifi units and all wifi devices are within line of site with each other, so this is not a reception problem. I've moved units around and tested multiple times)
I've tried this test using several different wifi aps as the internet source and compared this to connecting my clients directly and this is a very repeatable issue. The clients connecting directly to the internet sourced wifi ap have no problems browsing at all! Only when routing via the Opal using 2.4 GHz as backhaul does this problem appear. It's very frustrating as I sometimes travel to places that only provide 2.4 GHz internet access.
This has been tested both on the 3.x and beta 4.x firmware. Same result across the board.
I see many posts about connection drops with repeater but none specifically call out this configuration (2.4 GHz as backhaul) so putting this out there for feedback.
I'm considering returning this unit if I can't solve this as it's clearly been an issue that's plagued these series of routers for a long time.
