| I also have three Chromecasts and occasionally 7-8 mobile devices that are connected to them in multi-AP network. I have mostly Sony devices and I think they have a rather aggressive powersave profile. The last 3-6 month or so, the mobile devices have been losing connections to Chromecast while playing, and the network have become markedly more flaky also for other devices. I actually got a Chromecast Ultra with an ethernet connection in case the wifi was bad, but it didn't really make a difference. At some point a D-Link AP that is also the main router started to hang at least once per day, occasionally every 5 minutes. I installed Lede on it in order to rule out hardware problems - and then it stopped crashing at which point I stopped bothering, but I suppose the hardware can still be cooked. I've noticed that the network occasionally is really slow for a short while - I managed to measure the speed to an external provider to be around 4-5 mbit/s instead of 100, but I haven't considered the possibility that it's my own network that goes bananas. The WAF is declining, but it's so much junk that can go wrong so it will take a considerate amount of time to debug. Edit: I must say though, that I expect my routers and APs to survive 100.000 packages... |
Its the equivalent of having an 802.11B client that only syncs at 1Mbps and is constantly downloading. There is no airtime left for anyone else!
Things you can try: Block 802.11G and lower clients (increases your minimum WiFi transmission speed), convert multicast packets to unicast (LEDE is apt to support that), or throw the chromecast in the dustbin!
