No issues with internet speed (consistently above Sonos requirements) no data limit issues either ans we consistently use only 50-60% of monthly allotment. Only the ERA 300 speaker having connection issues. Have an older Play speaker that is outside in a shop that works just fine where the wi-fi signal has to pass through grarage walls and shop walls. The SL speaker is connected by ethernet to ISP router. ERA 300 is “ganged” with the SL speaker as it had been constantly disconnecting from wi-fi. No walls between SL and ERA 300. ERA 300 shows green light. App shows the speaker is connected and streaming…. but no audio. I see that wi-fi extenders are not supported by Sonos. Looking for a solution to ERA 300 connection issues.

This issues has been resolved by Sonos Technical Support. As I suspected, the issue is the wi-fi nic in the era 300. This is why it is the only speaker with connection issues even when it is working from a speaker that has a wired connection. Setting a static IP will do nothing to troubleshoot or to fix an issue with the physical nic in the speaker. To be 100% clear … the issue is the nic (wireless network interface card) in the Era 300 speaker. How to determine this was completed through the troubleshooting steps I completed and have been documented in this thread, along with Sonos support team monitoring the speakers connecting to the network. Last step was to factory reset the Era 300 only which confirmed hardware malfunction. To anyone else experiencing this issue, setting a speaker to a static ip; 1) never adviced as DHCP is preferred and static ips are only used by devices controlling a network, 2) devices with a bad nic (wireless/net work interface cards will send bad packets on your network causing other connection issues. You will find that once the bad device is powered off your network will run fine. For my case, this device will be returned to Best Buy as a defective unit since it was purchased less than a month ago. If you are a “community support person“ supporting this channel please take note…. as someone who has supported more wireless devices connecting to underpowered wireless systems…. never suggest assigning a static ip as a solution or a troubleshooting tool… static ips are for firewalls, osr (open source router) routers, routers, network switches, servers/controllers only and to be absolutely frank … only shows that the person knows absolutely nothing about setting up or fixing networks. There is a reason why we use DHCP … and that is for security and to prevent any ip conflicts.

With your vast experience in networking (none Sonos specific) maybe you can explain my issue then?

Situation One:

I buy two new Sonos, follow the Sonos setup procedures and end up stuck in installation loops. Multiple power cycles, Factory Resets and router reboots change where things go wrong a bit but I never get them properly added and working.

I factory Reset them and power them down. I add static DHCP addresses for them to my router. When I power them back up the install proceeds perfectly on the first try and they are working.

Situation Two:

After any power interruption or firmware update my system becomes unusable, speakers not found or refuse to play.

Another power cycle, carefully powering up one at a time and giving it a chance to fully boot and connect usually gets the system stable.

If I add static IPs to the router and do a power cycle, powering them up as quickly as possible (not as fast as they’d see in a real power fail/restore) they all come up and work perfectly. They also recover from a firmware update without issues.

Suggestions?

I’m not the only one here that would love a workable solution outside the static IP one.

Actually, yes, I do.

Biggest issue(s) on networks is the boot up time and sequence. An old proverb… “haste makes waste.” On my home network, i know that once I power my ISP modem/router back on after a full 3 minutes of being off; that my wi-fi is not ready to accept any requests for connection for a full 5 to 7 minutes. Then bring items back on one by one. Networks need to establish their protocols and aren’t instant off / on. Any other questions beyond this, you will need to register for my class.

Well darn it, I was hoping you could tell me where the boot-up delay was in my Sonos settings to solve Situation two.

Doesn’t explain Situation One at all though.

No money for classes these days, neither the Army or Computer Sciences Corp. are willing to shell out for more training since I retired from them.
