No information we users can look into to try and help you so I’ll assume you are just unhappy, not seeking help.

As this is a user to user community, with minimal Sonos presence you might address your complaint to Sonos Support.

Your post suggests you tried the same course of action each time, with the same outcome each time. 
Is it time to try an alternative approach to try and resolve the problem?

ok, I’ll give some details. Now I’m having an issue with the app not seeing my system with all my speakers connected to it, saying that there is a wifi problem. I’ve reset the router and modem. Also, done the recommended factory reset of the speakers which had to be added to a new system. Then, it worked. 

1 day later, same problem. There is some sort of wifi update that needs to happen but keeps bombing out saying it can’t be completed. That’s for the play 1 speakers. My sonos beam soundbar is dead without the update that I can never get to work unless I plug it into an ARC HDMI port on the back of my TV. 

Basically, how do I keep these things updated without dropping from my system and being unusable whenever there is an update that the speakers need?

Every time I have to do a factory reset to a simple speaker, it makes me think why they didn’t just bring back the old app until the new one was better tested. 

Nobody should be resetting their Sonos.  It doesn't do anything a simple reboot won't do, and it erases important dignostic data.  See link for more:

First question: who recommended a factory reset? 

Second: is your system fully updated? You’ll need all versions of the app and all speakers to be on the same revision. It can help to temporarily wire a speaker if you’re having problems updating via wifi. 

Third: if you restart your router and modem you should restart your speakers too - ip address conflicts are a common issue otherwise. Power down everything, then restart modem. When it’s fully running, restart wifi. When it’s fully running, start speakers one at a time. Start any surround speakers after the soundbar. 

If the simple restart everything doesn't work you can assign static/ reserved IP addresses to all Sonos followed by another power down all Sonos, reboot router and controller then powering the Sonos back on.

It might not be your main problem but it is a common and hard to diagnose one, best to eliminate it to make finding other issues easier.

See your router's DHCP Settings page for instructions on setting addresses.

Agreed; that was going to be my next suggestion. It might explain why the system works for a day and then plays up, as outlined by ​@kal12345 in an earlier post.

At this point, please stop arbitrarily resetting things. Tell us about your network. 

• Are you using your own router or one provided by your ISP?
• If provided by your ISP are the router and modem combined into one unit or are they separate?
• Is your network comprised of a single router or is it a mesh network with a router and one or two satellites? 
• What are the brand names and model numbers of your network gear (such as  Netgear, Linksys, TP-Link etc.).

I have my own modem (surfboard 1 gig ) so pretty good, also a nighthawk router that is also pretty decent but can’t remember the model. But they are connected with cat 6 no mesh router just the one unit in the middle of the house. There are no issues with other devices in the house. However, I did have to reset the cache recently on my router due to a service upgrade. That might have disrupted the sonos settings. 

Below are the factory reset messages I get from the app.

Thanks for the info about your network. Make sure your Surfboard is running DOCSIS 4.0. Years ago I ran my own modem and router. Today I use my ISP’s modem as it keeps them responsible for the incoming signal interpolation to my personal router. Using my own modem relieved my ISP of any responsibility outside of providing the signal to my home. So unless you are getting a substantial discount using your own modem I recommend letting your ISP supply their modem even if the router/modem are a single box. The router portion can be turned off or placed in Bridge mode to avoid two WiFi signals. Not saying that using your own modem is the cause of issues with Sonos. However, not doing so eliminates a possibility. Also know that other Wi-Fi or wired components are  not placing the same strain on your network as does Sonos. Sonos is very “chatty” as it’s constantly talking. Make sure that Airtime Fairness is turned off and there’s no band steering implemented by your router. My apologies for the length of this post as it may or may not resolve your issue.

thanks for the help, I’ll dig into the recommend solutions. 

Are you using iOS? If so , gave you considered using the SonoPhone or Clic app… no issues at all since I started using them months ago. 

Kal12345 my experience is the same.  My frustration is high. I have restarted my speakers multiple times and the problems remain. It takes minutes for the app to not only to play the music or content, I want to hear.It can also take two minutes for the system to acknowledge that."Hey I have speakers." I agree that sonos had one job. There are many products in the world that simply work when you turn them on. This is not one of them.

Submit a diagnostic and call Sonos support and they can likely help you with the problem. 

Apologies for not having included this in my original post. I have contacted and spoken to representatives of sonos, customer care more than twice. Each time I express my concern, they acknowledge that there are errors in my system, and they clear them up. And then the errors recur. 

I like having nice things and I am willing to pay top dollar for them. For the price point of a multiple speaker sonos system, I expect it to work. That I had to call more than twice to fix errors in the software does not align with the performance of a strong product. 

The emperor has no clothes.

What are they telling you is going wrong?

Give us something to go on and maybe we can suggest something the support folks missed.
