5Ghz connection from router to extender on RE300 drops out
Hi! I bought an RE300 about a month ago and started having issues a few days after setting up.
The connection between devices (eg my phone) and extender is fine, but between the router (Virgin Superhub) and extender it is not.
When I turn the extender on, the WiFi works fine...for about 30 minutes. But after that time period, I get an ! symbol on http://tplinkrepeater.net even though the signals for both channels say "strong" and the extender (for both channels) doesn't work. Turning the extender off and on again usually solves the problem, but only for about 30 minutes before it goes again.
I've worked out that the problem is due to the 5Ghz channel because:
If I go into high speed mode with 2.4Ghz router to extender and 5Ghz to devices, the connection is steady 24/7 (but slow and mostly useless.)
If I go into high speed mode the other way, it fails.
If I go 2.4Ghz all around, it works but slow.
If I do 5Ghz all around, the connection fails.
If I have everything on, it fails.
(Worth noting, the 5Ghz channel works fine on all my other devices when I connect directly to the hub, so that isn't the issue.)
So the problem is clearly the 5Ghz channel, but I can't work out why it keeps happening. I've checked for firmware updates but I can't find anything.
Thoughts? Thanks for any help in advance :)
