I still need to do some more neatly-configured things with my server and my LAN. It has all evolved with less thought about the number of switches and some other things. I had an i7-2600K system I'd refurbished and set up for my 92-year-old Moms. She's suffering cognitive decline -- broke her hip -- has to stay on the first floor of the house in a new "bedroom" we've provisioned for her. She wants her computer back. Originally, all these systems used wired Ethernet gigabit. Because of the arrangement with her new room, I didn't want to run another twisted pair wire from a switch in my room -- also on the first floor. Certainly -- I don't want any wires running along the carpet or even the baseboard. We can't have any hazards with Moms. We just replaced our CISCO-Linksyks E2000 router with a Netgear Nighthawk R7800. The E2000 just burned out after running 24/7 for about 8 years. The Nighthawk features Wireless-AC. So I picked up a TP-Link Archer Wireless-AC NIC for Moms' box. Everything works just fine. We used the stronger 2.4 band even for the slower speed of 450 Mb/s. I need to confirm, but sometimes I thought I saw the connection speed amp up to 1 Gb -- possibly for the duplexing -- I dunno -- maybe my imagination. But it's fast enough. So I thought to try setting up Media Center (Windows 7 64) to access the two HDHR-Primes I have down here on the first floor. These are connected to a switch, linked through a cable-drop to an upstairs room (my brother's) where the Nighthawk sits next to the cable-modem and another switch. I've yet to confirm whether this last switch lies between the downstairs unit and the Nighthawk, or the connection goes from the Nighthawk directly to the downstairs switch. I think I would've done it this latter way, though. In my room, I have another system with wired connection to the switch with the two HDHR-Primes connected. It has been my main Media Center Live TV and DVR system, and runs most of the time. When setting up WMC on Moms' wireless-AC box, I could get all the premiums, and things worked pretty damn well. But if the system went to sleep or hibernated, WMC would report either a "tuner conflict" or a perpetual "searching for tuners" message. Sometimes this latter message would resolve itself and the last selected TV channel would display. I noticed when I shut down the WMC in my room, it was much easier to raise WMC on Moms' system without a hitch displaying Live TV. Then I could restart WMC on my own system, and everything would be fine -- until -- until Moms' system went to sleep or hibernated. I also have the HD HomeRun DVR (Beta -- as far as I know at the moment) successfully installed on another system and working properly. If all three systems are displaying Live TV cable premiums or encrypted channels, there is never any problem with the HDHR-DVR system or my other Win7 WMC. And if WMC is displaying Live TV, no problem there with all three systems and LiveTV -- as long as I don't restart, shutdown, or sleep Moms' wireless-AC system. I have to iron out these quirks. Any 92-year-old with memory-problems, an anxiety disorder and a lack of patience would simply go bonkers. And that's the opposite of the environment I want to create for my parent.
