I have been dealing with my TiVo Roamio Plus problems (black screen from standby & wifi connectivity) since August 26, 2013 and figured I would now come to this forum that I recently found to share and possibly see if anyone else has the same problems (I was told that I'm the only one reporting these problems). This post will be long, because it is detailed. If you are interested in it, please read all the way through it. BACKGROUND INFORMATION: For the past two years, I have had a Premier XL4 in our TV Room that worked FLAWLESSLY... PERFECTLY. The XL4 was connected to my Sharp 70" HDTV (LC-70LE600U) through an HDMI cable with sound coming through the optical cable into my AV system (surround speakers). Additionally, the XL4 had a TiVo USB WiFi "G" Adapter connected to the USB port on the back of the XL4. We would watch our programming and when finished, my wife and I like to use the "Standby" feature found in the menu choices (under "Settings"). Standby would allow the XL4 to shut off the front LEDs and also to cease output to the HDMI and audio. Every single time that we brought the XL4 out of Standby, we would get our picture and sound without a single problem. No matter if we put it in Standby and pulled it out of Standby in 3 minutes, 3 hours, 3 days, or 3 weeks, every single time, it worked. Additionally, every single time the XL4 was rebooted (whether a "warm" reboot through the menus or a "cold" reboot by unplugging the power cord) the XL4 would reconnect to my wireless network without a single problem. And the XL4 was set up for DHCP (automatic) connection. NOW TO THE TWO PROBLEMS: Back on August 26th, I received my new Roamio Plus. I eagerly anticipated the arrival because I would now get 6 tuners instead of 4 and the ability to stream within the Tivo Roamio Plus instead of buying the stream box. So, I set up the Roamio Plus in the EXACT SAME spot as the XL4 used to be (the XL4 was moved to the far end of my house where the kids (teenagers) use it, play XBOX , etc). So, I entered my WiFi information into the set up screens and it went along well, UNTIL it rebooted. Then no WiFi. I thought this might be a temporary anomaly because the Roamio Plus was getting major software updates. So I continued. Finally the Roamio Plus was all set up and working. Or so I thought.... After I watched some programming I put the Roamio Plus into Standby. When I went to pull it out of Standby (by pressing the TiVo button), the screen stayed black. I could still hear the TiVo menu sounds, and found that if I went down 6 times and select, and then down 5 times, it would go into Standby again (even though I couldn't see any picture on the screen). And sure enough, it did. The lights on front went out. When I pressed the TiVo button a second time, everything came back normally. Picture was there and so was sound. So, I thought maybe this was a one time thing. NOPE. Very randomly the TiVo Roamio Plus would come out of Standby with no problems and other times not come out (meaning to keep a black screen). So, after my first call to support, the HDMI cable was thought to be bad. Even though this same cable worked FLAWLESSLY with the previous XL4, I decided to replace it. I bought Monster cables HDMI (it was on sale) and connected that. Same black screen issues. ALSO.... each and every time the Roamio Plus was rebooted/restarted, WiFi connection would be lost and I would have to go back into the Network Settings and reestablish connection to my network and enter the WPA2 password. (remember.. the XL4 never had a problem.. and still doesn't). SO.. it was determined to replace the Roamio Plus. While I waited for the new Roamio Plus to arrive, I brought back in my XL4 from the far room of the house and connected it back to where it USED TO BE. And no problems. NONE. Everything worked fine. The new Roamio Plus (the second, replacement one) arrived in early September . And after following set up procedures. the SAME two problems existed. (Black Screen out of standby and loss of WiFi connectivity). Now I called again and was connected to ADVANCED SUPPORT. They listened to all the above. With me stating that the XL4 NEVER had a problem and still doesn't. They asked me to use COMPONENT video connections (Red-Green-Blue for those of you who may not know). So, I used Component. And it was slightly better in that when coming out of Standby it would usually work.. BUT.. sometimes it did NOT work... and the same black screen. And if I scrolled down, select, scroll down, select (blindly since there was no picture) it would go into Standby and when coming out all would be good again. Moreover, the Component cables did NOT solve the WiFi problem in any way, shape or form. Reboot=loss of WiFi. After numerous discussions with customer support, I wrote a letter to the TiVo corporate office and was contacted by TiVo Executive Relations. And for the past three to four weeks I have been discussing solutions to this problem with an Executive Relations specialist. Things we tried, that did not work to solve either the standby problem nor the wifi connectivity problem: 1) I do not use MAC address filtering; 2) I've switched the Roamio Plus off of DHCP (automatic) connection to my WiFi and I assigned it a STATIC IP, and remembering to Reserve the IP address in the DHCP table of my router (Linksys E4200) series. 3) signal strength at the Roamio Plus location is 90% or better on Channel 11 in WiFi settings... neighbors are either on Channel 6 or 1 (I scanned with a tool I use); 4) HDMI cable replaced with new, Monster brand; 5) I did switch to Component cables, and we still have the problems.; The most recent (done yesterday) thing we tried was a "location test": move the TiVo Roamio Plus into the far room and connect it to a completely different HDTV (Sharp LC-46SB54U) first with HDMI, and still had the problem, then to Component and still had the standby problem. WiFi lost connectivity every time the box was restarted. INTERESTINGLY, while I was testing the Roamio Plus in a different room with a different TV, I connected the XL4 BACK to the 70in TV in the living room and had my wife call in to the other room and the XL4 connected fine, no wifi problems. And no standby problems. SO.......... the two problems still exist. I even created a YouTube video showing the problem: http://www.youtube.com/watch?v=-YBpDQpAF1M There you have it. Sorry for this very long posting. It's just upsetting to me that this brand new TiVo device doesn't work properly, albeit the standby function I use is not used by the majority of the TiVo users, but it should still work. Same with the wifi problems. Thanks.
