ESP8266-DEV to OpenWrt connection problems...

[a10lime]

Hi, usually Olimex's ESP8266 boards work like a charm for us and easily connect to standard 802.11gn networks, set up by Linksys or Netgear routers.

We have been trying to connect the Olimex ESP8266 to openWRT development boards (with MTK MT7620N and MT7688AN chipsets) and have been experiencing extreme connection problems. Only Sometimes, maybe 1 out of 100 times a connection can be established. The weird thing is that ESP8266-01 and ESP8266-201 boards from ebay perfectly connect to these boards every single time.

We have tried at least 10 different Olimex boards, same issue all the time, same software. What could be an explanation for that? We also tried all different kinds of OpenWrt configurations, channels, encryption types etc. etc.

Any help, ideas or suggestions would be appreciated!
Thanks!
