I have a Insignia Roku TV, 5408X. Software version is 8.1.0. 4140-20
I've had the TV for a year, and up until the last few months it worked fine. But now I've been having a network issue-- the wireless connection would only work for around 10-15 minutes streaming on any channel, before it would buffer, get a network error, read "You're not connected to the internet," and essentially crash the channel. I would have to return to home and disconnect/reconnect the wireless network and then go back to streaming, only to have to do it again in 10-15 minutes. This was making the TV basically unusable.
I tried various online fixes (system restart, software update, the "secret menu" stuff) to no avail until last night I just decided to do a full factory reset. Set the account up again, got connected to the same old network, and voila! I streamed Netflix for a few hours with no buffering or crashing. I thought I had fixed it, until today, a day later, it's back to the same thing-- disconnecting every 10 minutes.
I don't think this is a problem with my router/internet, because other devices in the same room work fine. It also says the signal strength is "Good" or "Excellent," and I never have any buffering/signal strength issues in between the crashes, which is confusing to me. It seems like it's just dropping the connection at random. If anyone has any idea what's up I'd gladly appreciate it.
I am having network problems with buffering and internet connection errors, which are intermittent. My Roku software is up-to-date. Doing a connection check shows speed excellent, but Mbps shows consistently 25-26, where doing a speed check on my iMac shows download Mbps of 153, upload of 20. My other devices connect with no problems, never have a buffering or internet disconnect error. Any suggestions why speed on Roku TV shows so much less? Also, what can I do to fix it? Thank you for any help you can provide.
My Roku players never show a speed that matches what my actual Internet speed is. However, you didn't say of you're using wireless or Ethernet. If you are wired, remember that the Roku only has a Fast Ethernet connection, which tops out real world at about 90 Mbps. But yours saying 25-26 is low even for Roku reporting standards. If you're wireless, you could be getting interference on your wireless channel from other devices or routers. Changing the channel your wireless router uses is a good first step.
My Internet is 90 Mbps down, but my wired Roku devices never report any higher than 55-60 Mbps. Switching to wireless they report even lower. But I don't encounter any buffering on anything other than my UHD movie rips, which can exceed 130 Mbps peak data streams.
