This is weird. I've looked (and searched) the forums so apologies in advance this is already resolved or has a FAQ or something. I've requested help from Poly customer care but they're blaming my LAN without offering any real suggestions.
Situation:
I have recently bought two OBI2182 to replace a couple of Obi200 and (old) Polycom POTS speaker phones. The 2182's are running Software version 6.2.3
The phones works perfectly until I shutdown or suspend my laptop (a Thinkpad X1 Carbon running Kubuntu 21.04). Then they drop off my LAN and stay off until I power cycle the units. (I.e., I can't ping them nor connect to them via my browser, a soft reboot doesn't help). Powercycled they work great until the next time my laptop shuts down.
I've fixed the DNS servers to 8.8.8.8 & 8.8.4.4 to no effect. The phone is configured to use Google Voice & 12VoIP, obviously both become unavailable when the phone drops. I also tried fixing the Switch Port 1 Speed to 100 AUTO, also to no effect.
One of the phones is connected to and powered by a Netgear GS305P switch (which my laptop is on). The other is on a different LAN segment and powered via its own adapter. Since it drops at the same time my desktop switch is presumably not the culprit.
Anyone seen this or have a fix?
Thanks.
