global DNS issue on all devices

[robertkwild]

hi all,

got a weird issue when i lose internet on my pc (ethernet) and mobile (wifi), when i go to

interfaces > diagnostics > ping

i ping google.co.uk/google.com/scan.co.uk using the wan interface and all good, i get a responses for all

but still no internet on mobile or pc, the only way to get internet working again is to save the global DNS settings again

system > settings > general

when i click the save button, my internet works again, im still using, i havnt changed any settings on the page

thanks,
rob
