The problem laptop successfully connects to another network on a different router (192.168…) but fails to ping on Omnia (172.28…). Both WL and LAN fail ping on 172.128… Other computers are fine on 172.128 as WL or LAN. I don’t think that I fiddled with the router and I don’t know where to start.
Model Turris Omnia
OpenWrt omnia 15.05 r47055 / LuCI 49c3edd5861fd032fa8379ceda525c27a908a114 branch (git-17.212.24321-49c3edd)
Kernel V. 4.4.113-1e4a549d177ab3da12b2052fba6a4dd5-1
Solved. I discovered a BSSID entry that didn’t exist on other machines. Removed it and all is good.
Thanks
