I don't have a solution but I also have the same problem with same router. It's wifi stops working randomly for me, but connectivity on ethernet ports is usually fine. So restarting it works. Otherwise, I have a second router running openwrt connected to it's ethernet port as the wifi hotspot, and it works fine.
