TiVo Roamio - Network Issues

Advertisements

I tested with an old LinkSys 24-port gigabit switch yesterday. No problems at all. So in our case it's definitely a combination of the Roamio and a "green" switch. I am tempted to try and find a "green" 10/100 switch to determine whether it's related to the use of a gigabit port.

I wish Margret would chip in to let us know if TiVo is actually looking in to this issue - I am spending way too much time on this.

 

I see a lot of mentions of the TrendNet 8-port gigabit green switch, myself included. I've tested the 5-port version of the exact same make/model without issue. I wonder if there is some incompatibility between the Roamio and the chipset used in the TrendNet (and perhaps shared with other brands that are experiencing problems).

I switched to a cheapo Monoprice 8-port gigabit "green" switch and haven't had any trouble, so it's definitely not all "green" switches.

 

I have found that the easiest way to test for the problem is using YouTube - just set a long 1080p video running (I used one on Glacier National Park) and leave it for a while (you don't need to sit and watch). If the network connection chokes, you will find an error message on screen when you return.

 

In one of the other threads someone identified that they too were using a green switch without issue. It doesn't seem to be all green switches and even for those experiencing problems, some are affected more severely than others.

We may need to be careful here. How long is the video? I can stream a full hour show on a Trendnet green switch without issue sometimes, and other times, within 10-15 minutes there is a problem.

 

Anyone know where to find a non-green gigabit 8 port switch ?

 

Wow - you are lucky! It takes less than 5 minutes to crap out of YouTube on my setup. I think the documentary I referenced is about 50 minutes.

 

This one doesn't appear to be green (I checked the manufacturer's web site and the manual): www.amazon.com/Tenda-G1008D-Desktop-Unmanaged-Ethernet/dp/B006KAP54A/

 

There can easily be issues with 802.11.az or "Green Ethernet". The internets is full of odd things and for good reason. Lots of SOHO switch manufacturers jumped on the "Green Ethernet" trend prior to the ratification of 802.11az. The technology is suppose to be able to detect line length and with some signalling, put interfaces in sleep mode. Of course this means both ends need to be compatible and not have any bugs to make it all work.

Switches of the same model from the same manufacturer can have different firmware. If you have a "Green Switch" and are having problems you can try to A) disable the green feature if possible, B) upgrade the firmware of the switch if possible, C) replace the switch with one that is either non-green or known to work.

My Roamio Plus is plugged into an old Netgear GS108T gig-e switch which then connects to the house primary Cisco 3570 switch. The mini is connected to a new Netgear 5 port gig-e switch which is a pro-safe GS105 that has auto-power down. Neither of mine are experiencing issues.

 

Thanks ! May have to buy that one.

 

Just a quick note to reassure everyone we are actively looking at the "Green switch" issue. Sorry for the trouble -- and thanks for your patience!

I had a "network issue' today.

It successfully connected to TiVo Service but I was unable to access the HDUI features. TiVo Support suspected it was the switch and recommended going wireless since I don't have MoCA gear. That seemed to resolve the problem but I may need to set a permanent IP and/port forwarding if it didn't. Ethernet with a Netgear GS108NA ProSafe 8-Port Gigabit switch works great with other things (Roku, Apple TV, Vulkano, a camera hub, and TiVo HDXL) but apparently not the Roamio Plus.

I'm feeling a firmware update imminent to resolve these "network issues."

 

Many thanks. It would be helpful if TiVo CSRs were not telling customers that TiVo is not supported when connected to a switch, and posting that in the forums.

 

That's great, thanks Margret!

 

I am also having issues with the Green switches (Roamio/Minis). No problems with anything else connected to the switch--including another media player. This is definitely a TIVO issue.

I have both Netgear GS105/108 switches (plus a managed Dlink 24 Port backbone switch). Full gigabit network that works perfectly--except with Roamio/Mini.

 

Update after messing with my home network all day:

I moved switches around and bypassed switches. My home is wired with dual drop Cat6 gigabit Ethernet in all rooms, all terminating at a 24 port Managed Dlink switch. At some locations, I have inserted Netgear GS105/108 "Green" switches in order to connect additional items (AV receiver, media player, TV, HTPC, etc).

I have been able to determine (at least for me) that connecting a Netgear GS105/108 switch next to a Tivo Mini works fine. Connecting a Netgear GS105/108 switch next to the Roamio causes my problems. Prior to bypassing the "Green" Netgear switch connected to the Roamio, I was having constant connection issues. If I bypass the "Green" Netgear switch next to the Roamio (direct connection to Dlink 24 Port switch), the Minis have been able to stream live TV for the last hour without issue (prior to removing the switch, it would lose the connection in 3-10 minutes). This occurred with two different Mini devices in two different rooms (both connected via Ethernet to a gigabit home network).

Maybe this helps someone troubleshoot their issues in the future. Good luck.

 

How can a live devise such as a Tivo/Mini be seen as a dead device by a "green switch". My Mini shows net activity even though it's been sitting there for 3 days not being used. Seems the switch should become "smart" before it goes "green". The only time any of my devices show non-activity is when they're turned off.

And similar technologies

 

Do most of these green switches have settings that you can access to turn off the "green" technology?

 

Consumer switches do not typically have management capabilities to do things like that. Certainly the reasonably priced products do not.
