I plan on filling this page with weird configuration notes for various things. Hopefully someone will find this useful.
If I get enough on here, you may need to scroll down the page to look for whatever the search engine sent you here to find. I'm not a web designer, so lump it.
Problem:
DVD video cuts out on a 4K Blu-Ray player. Also, DVD audio cuts out on a 4K Blu-Ray player. I have experienced this on both Sony Blu-Ray players and Panasonic Blu-Ray players.
Solution:
Disable 4K upscaling. How to do this varies from model to model, so you will need to consult your manual or look through all of the settings for the player.
Reason:
DVDs are 2K or lower. To give the best video quality on a 4K TV, it uses upscaling to convert it. Some Blu-Ray players do not do this well, probably due to an underpowered CPU not doing the math quickly enough. When it cannot keep up, it momentarily resets which causes the video and audio to cut out.
The video will not look as good when playing a DVD, but 4K Blu-Ray disks will still look good. As someone who grew up watching analog television where the programs would sometimes have "snow" and audio hiss, I can say that you will get used to the lower quality video pretty quickly unless what you are watching is really boring.
How to properly configure the LAN2/WAN2 port on a Ubiquiti USG firewall
- In the VLAN config, you have to add the second VLAN to the LAN2 "Network Group".
- Even after you do this, the LAN2/WAN2 port will use TAGGED packets, not the native VLAN. So the port you are using on your switch needs to have native VLAN 1, tagged VLAN 2. (Assuming your VLANs are numbered 1 and 2.)
- The edge level ports for devices you want on VLAN 2 can use native, you just cannot use it for the connection to the LAN2/WAN2 port on the firewall.
- If you only want one device connected to the LAN2/WAN2 port, it will either need to support VLAN tagging or you will need to run it through a switch that does. There does not appear to be a way to have VLAN 2 be the native VLAN on that port.
The problem with products like T-Mobile Home Internet and similar products
It is basically a hotspot with a better power supply and stronger wifi, but it is still beholden to 5G signal strength and tower congestion, same as any phone used as a hotspot. In theory they are using QoS on their towers, but in busy areas it's still probably going to suck.
If you are using corporate VPN or a VoIP product, you are likely going to have issues. VPN and VoIP require a constant connection and do not tolerate packet drops or high latency.
Don't blame your corporate IT department is what I'm sayin'. Get cable or fiber if you want stability.
