Can you use a VPN on an Onn 4K streaming box? Yes. Walmart’s Onn devices run Google TV, which is built on Android TV, so Android TV VPN apps install from Google Play. The model you own matters, though: the 2026 Onn 4K Pro has 32GB of storage, Wi-Fi 6 and an Ethernet port, but that port runs at only 100 Mbps, smarttvs.org notes, while the cheapest Onn 4K has just 8GB of storage, Walmart lists.
This page compares the Onn models for VPN use, covers setup, and explains the speed limits worth knowing.
VPN for Onn 4K: Which Model Do You Have?
| Model | Storage, RAM | Network |
|---|---|---|
| Onn 4K Pro (2026) | 32GB, 3GB | Wi-Fi 6; 100 Mbps Ethernet |
| Onn 4K Plus | 16GB, 2GB | Wi-Fi 6; Ethernet via USB-C hub |
| Onn 4K (2026) | 8GB, 2GB | Wi-Fi 5 |
All run the same VPN apps. What differs is room and speed: an 8GB model fills quickly, so a VPN app competes with streaming apps for space. Compared with the 2024 model, the 2026 Pro dropped from 4GB to 3GB of RAM, smarttvs.org notes, still ample for a VPN.
Walmart sells Onn boxes for US use. Its listings mark the devices as US-compatible only; the VPN apps themselves aren’t affected, but taking one abroad isn’t what Walmart designs them for.
How to Set Up a VPN on Onn 4K
| Step | What to do |
|---|---|
| 1 | Open Google Play on the Onn box |
| 2 | Search for your VPN and install the Android TV app |
| 3 | Sign in, ideally with a QR code from your phone |
| 4 | Pick a nearby server and connect |
| 5 | Turn on split tunnelling for apps that need your normal connection |
When you set up a VPN for Onn 4K, QR sign-in avoids typing with the remote, and NordVPN, Surfshark, ExpressVPN and Proton VPN all have Android TV apps, as our Google TV Streamer guide covers in more detail. Surfshark and NordVPN share a parent, Nord Security.
Speed: Wi-Fi Can Beat the Ethernet Port
The Pro’s Ethernet port tops out at 100 Mbps. On a fast home connection, Wi-Fi 6 near the router can be quicker, and a VPN adds its own overhead, as our speed guide explains. 4K streams need far less than 100 Mbps, so either works for video, as our Netflix guide notes for streaming.
Pick WireGuard or NordLynx for a VPN for Onn 4K. Lightweight protocols suit budget chips, as our encryption guide explains for devices without heavy hardware.
If the VPN Misbehaves
Clear the VPN app’s cache first, then switch protocol or reinstall, as our Android fix guide explains; Google TV boxes behave like Android here. If one streaming app fails only with the VPN on, exclude it with split tunnelling. To switch the VPN off entirely, see our TV VPN off guide.
