Travel routers and old gear: How to simplify networking without buying new

Travel routers are a niche but practical tool for frequent travelers, offering a familiar Wi-Fi network in hotels and other public spaces. However, they come with limitations—and alternatives like cellular tethering or repurposed old routers may be simpler or more cost-effective. Meanwhile, old routers can find new life as extenders, switches, or VPN gateways, reducing e-waste and cutting costs.

The basics of travel routers

According to Engadget, a travel router connects to an available internet source, such as hotel Wi-Fi or Ethernet, and creates a personal Wi-Fi network for multiple devices. This can be useful for travelers who need to connect laptops, phones, streaming sticks, or other gadgets under a single, familiar network name and password.

Travel routers can bypass per-device limits imposed by hotels or other public networks. For example, if a hotel restricts access to two devices per room, a travel router can distribute that connection to several devices. However, they do not automatically encrypt traffic, leaving it vulnerable on untrusted networks unless a VPN is used.

While travel routers provide greater control over an unfamiliar network, they cannot improve slow or unreliable internet speeds. They also require additional hardware and setup, which may be a hassle for some users.

Alternatives to travel routers

Cellular tethering via a smartphone is a common alternative to travel routers. Android and iPhone devices can share their cellular connection with other gadgets, eliminating some of the hassle of setting up a separate router. According to Engadget, many Android phones can even share a Wi-Fi connection over a hotspot, though iPhones are limited to sharing cellular data only.

However, tethering has its own limitations. Carriers may throttle speeds, impose data caps, or charge extra fees for tethering. Additionally, cellular reception can be weak in areas with poor coverage, making this option unreliable in some locations.

Repurposing old routers at home

Old routers can be repurposed into useful secondary devices on a home network, according to Engadget. Instead of discarding them, users can transform them into Wi-Fi repeaters, network switches, file servers, or dedicated VPN routers. This approach can save money and reduce electronic waste.

As a Wi-Fi repeater, an old router can extend network coverage, though it may reduce speeds due to limited wireless capacity. Some routers, like those from Asus, support AiMesh, which allows mixing different models to create a unified network. This can be a cost-effective way to improve coverage without buying new hardware.

Old routers can also function as network switches, expanding the number of available LAN ports. This is useful for homes or offices with multiple wired devices, as it avoids the need to purchase a separate switch. A basic network switch typically costs between $10 and $20, making this a budget-friendly option.

For those with technical know-how, an old router can be turned into a rudimentary file or print server by connecting a USB storage device or printer. While not as powerful as dedicated network-attached storage (NAS) devices, this setup can be useful for basic tasks.

Repurposing an old router as a dedicated VPN router can also help reduce battery drain on laptops and phones, as the router handles the VPN connection instead of the device itself.

Custom firmware and advanced setups

Custom firmware like OpenWRT, DD-WRT, and FreshTomato can extend the lifespan of an old router and unlock advanced features. These firmware options provide greater control over network settings, security, and performance, often making setup easier for tech-savvy users. However, not all routers are compatible with custom firmware, so compatibility must be checked before proceeding.

Using custom firmware can also help avoid wireless interference. For example, broadcasting two Wi-Fi signals in close proximity can degrade performance, but a single router with custom firmware can be configured to optimize signal distribution.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

For founders and operators, the takeaway is less about buying new gear and more about squeezing value from what you already own. Travel routers solve a real pain point—juggling multiple devices on sketchy hotel networks—but they’re not a silver bullet. They won’t fix slow speeds, and setup takes effort.

The bigger lesson is the sustainable angle: repurposing old routers as extenders, switches, or VPN gateways can save money and reduce e-waste. For startups in hardware, IoT, or cybersecurity, this validates the demand for modular, multi-use networking tools. It also highlights a gap: most travelers and home users lack the patience or technical skills to flash custom firmware or configure a repeater. If your product simplifies that process—without sacrificing security or performance—there’s an opportunity.

Key takeaways

• Travel routers provide a consistent network experience for multiple devices but require manual setup and won’t improve slow internet.
• Old routers can be repurposed into Wi-Fi repeaters, network switches, or VPN routers to reduce costs and e-waste.
• Custom firmware like OpenWRT or DD-WRT can unlock advanced features but isn’t universally compatible.
• Cellular tethering via smartphones is a viable alternative but may involve carrier restrictions or weak signals.
• Using an old router as a dedicated VPN device can reduce battery drain on laptops and phones.

FAQ

Do travel routers improve slow hotel internet speeds?

No. Travel routers distribute an existing connection to multiple devices but cannot increase bandwidth or improve slow speeds.

Can an old router be used as a Wi-Fi extender?

Yes. Many old routers can be repurposed as Wi-Fi repeaters, though this may reduce speeds due to limited wireless capacity. Some models support features like Asus’s AiMesh, which unifies multiple routers into one network.

Is cellular tethering a better alternative to travel routers?

It depends. Cellular tethering via a smartphone is simpler and eliminates the need for extra hardware, but carriers may impose data limits, throttle speeds, or charge extra fees. It also relies on strong cellular reception, which may not be available in all locations.

What are the benefits of custom router firmware?

Custom firmware like OpenWRT or DD-WRT can unlock advanced features, improve security, and extend an old router’s lifespan. However, compatibility varies by model, and installation requires technical knowledge.

Can a travel router encrypt all traffic by default?

No. Travel routers do not encrypt traffic automatically. Users must configure a VPN (e.g., OpenVPN or WireGuard) to secure their connection on untrusted networks.
