My Optus internet recently stopped allowing multiple devices to connect to the WIFI network and it will only allow one device at a time to connect. I have tried resetting router and modem and have tried all sorts of plugging/unplugging of cables, changing them etc. but can't work out how to fix this. I have seen a few similar posts whereby this happened all of a sudden and now won't work but haven't found a solution. Any help would be much appreciated as it is driving me mad! 🙂
what is your current setup? a factory reset on the modem/router usually resolve many issues. Give that a go if you haven't done so and see if that works.
