Dr. Geoff - Thanks. I was thinking exactly the same thing - bring it home and see. (And vice versa!!)
Now, if it works perfectly at home, that probably means my wife's mini-office landlord is doing something to limit the traffic even though our original deal from almost seven years ago was that the rent would include internet, and I was very upfront about that including our own VOIP phone.
But now I need your more advanced advice.Originally, in the mini-office, we plugged the landlord's ethernet wall socket into a small router - to the router's WAN socket. We then ran everything off the router's LAN sockets or WiFi. So, originally, our small VOIP box was "behind" the router (always wired to one of the router's LAN sockets).
We got our ObiHai 200 and our Google Voice about three years ago. Worked well. Then about a year later (two years ago), Google Voice dropped its original protocol, the ObiHai stopped working although it was supposed to continue working, and I came to the conclusion that our oldish router could not handle Google Voice's new protocol. (That router is an old Westell DSL modem-router that Verizon gave me a long time ago and that I converted to "routed bridge" to use in my wife's mini-office. It still works except for the ObiHai 200.)
So I bought a TP-Link TL-SG105 unmanaged 5-port switch, and now the ObiHai 200 is directly on the landlord's ethernet network and no longer behind our old router. In other words, that TP-Link TL-SG105 unmanaged 5-port switch is connected to three things: the landlord's ethernet socket, the old router's WAN socket and the ObiHai 200. So the ObiHai 200 is no longer going through our router.
Maybe the landlord can now "see" the Obihai 200 as a separate device and is limiting its connection to the internet
QUESTION: What replacement router should I get so that, again, I can put the ObiHai 200 "behind" the router, the new router will be able to handle the ObiHai-Google Voice protocol well, and maybe the landlord will stop interfering? (Maybe the landlord will again see only one device??) Such a replacement router should also generate its own WiFi network for our iPhones and iPads when we're in that office.
FYI - the landlord's network bandwidth to us is only 100Mbps, but that's fine for our purposes.
Or could it be that the ethernet cable between my ObiHai 200 and the TP-Link switch is bad and intermittent
Thanks for your thoughts. ☺
