TP-Link Archer C60 v2 ath79, when enabled 5ghz radio, memory rapidly decreases and luci shows error within 1 minutes: Failed to create CGI process: Out of memory.
When I disable 5ghz radio in 1 minutes before error (under ~12mb) memory gets back to the normal (~30mb)
When 5ghz radio disabled there is no problem.
2.4 ghz works flawlessly.
