Buffering on a modern plan is a delivery problem
The services publish their real requirements and they are humbler than you’d think: Netflix asks 3 Mbps for HD, 5 for full HD, 15 for 4K; YouTube about 20 for 4K. Almost every Bakersfield internet plan clears that many times over — so when the wheel spins, the speed usually died on the last fifty feet: your Wi-Fi, your streaming box, or your router mid-nervous-breakdown.
Restart the app, then the device
Fully quit and reopen the app first. Then the streamer itself: unplug 30 seconds (Netflix’s own guidance; give cable boxes a full three minutes). Streaming sticks in particular run warm and hang — a stick that buffers every evening but never after a restart is telling you exactly what it needs.
Restart modem and router
Off thirty seconds, modem first, router second, two minutes patience — then retest the stream.
Compare devices
Same show on your phone, standing next to the TV. Phone streams clean while the TV buffers = the TV or its box is the weak link (old smart-TV apps and 2015-era sticks are chronic). Both buffer = network side.
Improve the TV’s connection
TVs sit in furniture at floor level across the room from the router — the worst seat in the Wi-Fi house. If the router is anywhere near, an Ethernet cable to the TV or box ends buffering permanently. Otherwise: closer router, a mesh node behind the TV, or drop the stream to HD on the far bedroom set.
The codes are all saying the same thing
Netflix’s common ones — NW-2-5 (“device took too long to connect”) and the tvq-st-103 family (“a network problem is stopping your device from reaching Netflix”) — are all network-reachability complaints, and Netflix’s own fix list for every one of them is the sequence above: restart device, restart network gear, improve the connection, remove VPNs or custom DNS, and sign out and back in. One more honest possibility when a single service stutters while others fly: the service itself is having a bad night — check an outage tracker before rearranging your living room.

Quick answers
Netflix buffers but YouTube is perfect — how?
Different services, different servers and app quality on your device. One-service-only trouble points at that app (update it, sign out/in, reinstall) or a service-side incident — not your internet.
Why does buffering always hit at 8 PM?
Peak hours: your household, your neighbors' airwaves, and the ISP's node all busiest at once. If a wired speed test also sags at 8 PM, that evidence belongs in a call to the ISP; if only Wi-Fi sags, it's coverage.
Does 4K need special equipment?
A 4K TV, a 4K-capable streamer or app, ~15-25 Mbps delivered to that screen, and on discs or consoles the right HDMI cable. The delivered-to-that-screen part is what usually fails.
Will a VPN cause buffering?
Frequently — encryption overhead and distant exit servers throttle streams, and Netflix's own troubleshooting says to remove VPNs. Test once without it before blaming anything else.
