My phone's wifi disconnects automatically. At first I thought this was an issue with my phone but when the same happened with my dad's phone too then I thought maybe the issue is with the router. Though my tv doesn't has this issue, don't know why. It keeps streaming while our phone's disconnect. My two neighbours use the same router as me (common isp, common peripherals). Other neighbours are nearby too.  Can the issue be because of wifi channel crowding ?  If I manually change the channel will it help ? Also if there's anything other than this please do give suggestions. Thanks.
