Hi there, I am having very poor experience with the stock WiFi card in udoo bolt gear. Icmp to my router are approx 7 seconds (no mistake here) and connectivity fades to none in a distance of 3 meters from the router. Obviously, other devices work fine on this router on any of dozens Wifi I have, any radio, up to real transfer of 700mbit/s. So I have questions: is it known issue? Is it metal chassis so badly influencing the signal? I suspect antennas are same, bu maybe not and I connected 2.4 to 5ghz and the other opposite? I suspect I can use pigtail and connect external antenna, but happens I don't have one handy, will it fix the issue? Thank you and best regards.
