Hi Eric. Thanks for jumping in.
My iPhone rediscovery is typically 15-30 seconds, which is why it feels like an eternity. Would love to shorten that to a second or two.
I have reinstalled the Roon app on the Lenovo tablet a couple of times, without any different effect. Ah, my network. OK, here we go:
My main wireless router is an ASUS RT-AC87U. The network map shows I have 30 clients currently attached. Specific to the issues here, my router is direct connected via ethernet to my Roon core, which is running on an i7 CAPS Zuma server built by Small Green Computer, which I have configured to run Audiophile Optimizer’s latest version in minimal core mode, and to my Synology 1813+ NAS, which stores my music library. I also have JRiver MC22 running on the server at the same time, which I use, remotely via JRemote, to access my music library on my iPhone 7+ out of home.
The router is also ethernet attached to a Netgear GS116Ev2 16-port gigabit ProSAFE Plus switch. The switch is configured with no management – for example, IGMP Snooping and Loop Detection are disabled, The switch is ethernet connected to a SONOS Connect box, an Oppo BDP-95 bluray player, a Marantz AV7005 preamp/processor, an Apple TV (latest version), a Small Green Computer sonicTransporter (to Roon-ize my Bel Canto renderer and DAC), a Mitsubishi television and another PC.
I have aftermarket hi-gain antennas installed on the wireless router so as to have a strong wifi signal. The router is located in the lower level of our large home and I use a series of repeaters to get the signal to the main and second levels of the home. Those are separate challenges, but I don’t believe they impact the Lenovo tablet issue here.
When I am using the Lenovo tablet, I am sitting not more than 12 feet away from the main wireless router and I am connected to its 2.4GHz wireless network. Although I can’t get the Roon app natively to run, I can connect to Splashtop, which in turn allows me to link to the additional PC in the same room noted above, which is also running Roon. While Splashtop access certainly works, there are limitations that would make running the Roon app natively on the Lenovo an advantage.
All firmware on the router, switch, etc. are the latest. Connections otherwise throughout the home are all set up as 802.11ac wireless. In total, I have 5 Roon endpoints running on Raspberry Pi3s with DietPi and five different DACs, the sonicTransporter to enable Roon for the Bel Canto products and five SONOS Connect boxes.
In short, if my complex setup can run Roon, anyone can!
Let me know if you need any further detail to offer up some suggestions here for both issues. Thanks. JCR
