You can link your phone’s hotspot to stay connected when internet service is unstable. It fits a budget of $30–$50 and works in the US.
Consider purchasing an inexpensive router and switching it to repeater mode. If your internet connection drops, simply disconnect the WAN from the router, connect it to the repeater, and activate the hotspot. This method keeps your wired devices connected while reducing strain on the hotspot.
Consider purchasing a dedicated repeater or extender. When your internet fails, activate your hotspot and regenerate the signal from your phone. Options include the NETGEAR AC750 Range Extender EX3700 or the TP-Link Archer T6E. If you meant a WiFi card for your PC, choose between internal or external models.
I avoid repeater mode because it halves the maximum throughput by adding another wireless hop and competing for airspace, usually on the same WLAN channel. I prefer wireless client mode—also called wireless bridge or media bridge. I’ve seen good performance with an older router running DD-WRT firmware. During an upstream outage, activate your phone’s Wi-Fi hotspot (LTE tether), then connect: [Phone] – - - - - [Wireless client bridge] –------- [Your router’s WAN interface]. Legend: Wi-Fi (WLAN) vs. Ethernet
Using repeaters and extenders will cut your data rate in half. A properly set up dual or triple extender could work, but it would exceed your budget.
A Wi-Fi range booster is merely a marketing label for a repeater; essentially, they function the same way. These products are poor consumer items and I regret their existence since they worsen the radio frequency environment, raising the noise level for everyone nearby. My advice was to avoid using them at all. It seems the original poster already has a wired router as their primary connection point. If the aim is to redirect WAN traffic from an existing wired network—like a cable modem or fiber bridge—then connecting LTE directly to Ethernet, straight to the router’s WAN port, makes perfect sense. There’s no need for an unnecessary step through WLAN compared to a direct Ethernet link.
In short (if that’s still confusing):
- Perfect setup: [Phone] → [Wireless bridge] → [router’s WAN] → [PC]
- Suboptimal: [Phone] → [range extender] → [router’s WAN]
- Ideal: Direct wired connection bypassing the extraneous hop
- Key takeaway: Using 4G LTE as a WAN fallback is a smart enterprise tactic, similar to how a phone can replace a modem.
If you’re looking to upgrade, consider an older wireless router (free or cheap), compatible with DD-WRT or OpenWRT, and set it to “Client Bridge.” This lets it automatically integrate with your existing network. You can even hook up a 4G modem or radio as a backup, ensuring seamless connectivity.
I did that a few weeks back with my old Linksys EA6500 using DD-WRT, which functions as a wireless repeater bridge to my new Linksys WRT3200ACM. It works well and is useful for repurposing the old router.
