Since About a month ago we have had consistent problems with devices randomly losing internet but wifi connected. Happens on win 10 laptops, MacBook, android phones, iPads. We also have Smart Tv and Foxtel IQ box connected with Ethernet cable to LAN port. We are having regular issues on all devices where the connection to wifi router is ok, but no internet but not all at the same time. Especially of concern is the LAN connections dropping internet as it means the wifi signal isn't to blame.
If I reboot the router, it is ok for about a day before devices start losing internet again, so this is not a reasonable answer to keep rebooting.
do I need to replace the router or is there another issue that can be easily resolved?
