i bought two tv's from costco (hisense)
two of these plus another roku device connected to my older tv stopped working(connecting to wifi) out of the blue.
nothing changed in my wireless settings or my router.
i have tried every thing i could find only(channels/sonus..plus unplug reset ping,disabling 5 2.4, f.reset...) nothing seems to work, it just doesn't seem to connect to wifi.
all devices are up to date with updates.
if i dont get any solution to this thing im dropping both tv's at coscto for refund all my 40 other devices and tv's(not powered by roku) work fine even some very old legacy devices.
