OK, to summarize - my network is fine. My equipment is very new and all very current on the firmware, etc. The router is only 3 months old, current and fine. My Internet connectivity is not the router, it's the fact that I live in a black hole of cell signals. I have to have a REPEATER setup to use cell voice and 3g. My repeater doesn't handle 4g and my router is 4g only.
There's nothing weird about the equipment and it's functioning fine, it's just that it's hard to get a signal when you live at the bottom of a hill, down in a river valley surrounded by trees and hills. Internet loss at the router is a problem with everyone in our neighborhood. To use a cell phone unless you are in our house covered by the repeater, you have to drive about a mile.
The Internet loss every so often is a function apart from the Tablo other than when it's down, I can't connect to Tablo or access Tablo functions because the web apps, and the phones use the web apps, too, require my.tablotv.com which is an outside or external server. If you can't get to the web, you can't get to their server and thus a web-app on your phone or your PC can't get to your Tablo. Sad but true and they explained the why of that to me a while back so I won't bug them again on it - at least for a day or so yet.
If I had network troubles, I'd have other issues with Tablo. Tablo, my PC, my FireTV stick, my phones that connect to DATA through the router and all other devices work great. It's only 1 issue with tablo and recorded shows. Nothing else. I don't have buffering issues when using FireTV stick, and buffering is a tiny issue with Chromecast now that I've set Tablo to record at 720/Roku and Chromecast setting. It's a problem when the show had reception issues, seems Tablo chokes a lot of the reception isn't great but again, that was an issue with my cabling and splitting the feed a bazillion times over 1982 RG59 cable spanning over 100 feet. Not a Tablo issue, gotta blame me for that, not them.
I have one issue with the Tablo - that's its not saving my spot - no bookmark to go back to.
I have not tried it since the update as frankly I've been not in the mood for TV with a bad head cold and throat infection. No need to step back from your PC, it can't travel Ethernet yet....... and I hope my firewalls would stop it anyway.
My setup -
Tablo quad. Tablo wired to router, 6' Cat 5e cable direct to router from Tablo.
Tablo has a reserved IP address, and it's always had 192.168.0.100 since I first allowed it on my network. That address has never changed.
My router is a NG 2200d with the latest firmware. It sits near the TV and near a window to help with the cellular 4g reception issues.
I have my notebook computer, a later Toshiba with Windows 7 64bit in the same room as the router, TV, Tablo, etc. and it connects at n300 speeds at times, a solid as a rock n150 most of the time. Access to all things on my network are super fast, including remote printing to the printer in my main office, my server/computer in my office, and the web. Speed isn't an issue. The only things connected Wi-Fi are the notebook, our 2 Moto X phones (also very current) and my wife's Kindle Fire when she's using it. Everything Wi-Fi is in the same room, a max of 15' apart.
My wife is into online games and chats with her quilting friends and says performance is fine with her devices on the network.
I can get to Tablo FAST, I can switch tabs or pages fast, I can view live TV program guide, set a show to record in a second or two, view show info almost instantly, and show our recordings in the blink of an eye.
Traffic to and from all devices is good, fast pings, no dropped packets, etc. Firewall logs are clean.
If the Tablo recorded show bookmark or place holding isn't resolved with the latest firmware update for Tablo, I'll likely open a ticket with them so they can take a look-see and see what the logs are showing and check out my browser stats.
Since I mostly use the FTV stick now, I'm used to no saving my place. The web app is slower and more complex (more mouse clicks, etc.) to use Chromecast so I'll have to make special effort to test again with the browser. I generally now use the phones and computer to mark shows to record, check on things, check the program guide and so on. FTV is just so much faster and easier, it's hard to go back.
