My Roku Express that is literally only 4 foot from the router has started to drop wifi signal at regular intervals over the last few weeks. I have restarted, restored factor defaults, updated etc but it still drops wifi at least twice a day and always at a quarter to an hour (especially 9:45PM PST). If I'm not actively using it, I don't know if additional drops happen. I have also reset my router and ensured that it is at peak signal strength.
Additionally, when I check the connection it always immediately connects to the router and says it had great signal strength.
I have another Roku Express on a different level and a Roku Stick also right next to the router, neither of these are experiencing similar problems.
Does anyone have any ideas what I may be able to do to fix this.
