Your laptop connects to the internet. Your phone connects too. But the printer cannot be found, your streaming device refuses to appear, or your television and phone act as though they are on completely different networks.
That can happen when you are using shared internet.
The important thing is that not all shared internet is the same. Living for months in an apartment building with one managed network is a very different situation from spending three nights in a hotel.
A small travel router can be useful in both cases, but for different reasons.
Disclosure: Cudy has not paid me for this article, supplied me with a router, sponsored this post or reviewed it before publication. The same applies to the other manufacturers mentioned below. There are no affiliate links in this article.
Case 1: You live in a building with shared internet
Imagine an apartment building, senior community, student residence or other property where internet service is included and everybody connects to infrastructure managed by the building.
Your own devices may have perfectly good internet access while still being prevented from communicating with one another.
That is often deliberate.
Network administrators can enable client isolation, which helps prevent one resident from seeing another resident's computers and devices. From a security perspective that makes sense.
But it can also stop things you expect to work inside your own home:
- wireless printing;
- Chromecast or similar casting;
- local file sharing;
- discovering a television or media player;
- smart-home devices that expect your phone to be on the same local network.
If the apartment has an Ethernet outlet
This is probably the cleanest situation.
Connect a small router to the building's Ethernet connection and create your own private network behind it.
Your phone, computer, printer and television connect to your router instead of directly to the building network. They can then communicate with each other locally while your router uses the building connection for internet access.
The Cudy TR1200 1.0 is one inexpensive router that can do this. Cudy describes it as a USB-C-powered mini Wi-Fi router with router, WISP, access-point, repeater and client modes, as well as VPN support.
One limitation matters if this will become a semi-permanent apartment router: its two Ethernet ports are 10/100 Mbps. If the building provides an internet connection substantially faster than 100 Mbps and you want to take advantage of that speed, I would choose one of the gigabit-capable alternatives farther down this article.
If the building gives you only Wi-Fi
This is a different setup.
A travel router with WISP/repeater functionality can connect to the building's Wi-Fi as its upstream connection and then create a separate private Wi-Fi network for your own equipment.
For example:
Building Wi-Fi → your travel router → your laptop, printer, television and phone
That can solve the local-device problem even though the internet itself still comes from the building.
It will not work in every managed network, however. Some providers restrict routers, limit registered devices or use authentication systems that complicate the connection.
If this is your permanent home, it is worth asking the building manager or internet provider whether personal routers are permitted.
Case 2: You are staying in a hotel
The hotel problem is usually not that you want to install a permanent home network.
You may simply have five devices and a hotel login page that you would rather deal with once.
A travel router can connect to the hotel's Wi-Fi and create one private network for your laptop, phone, tablet and streaming device.
That gives you a familiar Wi-Fi name and password wherever you go.
Some hotel networks use a captive portal — the page where you enter a room number, surname, access code or agree to terms. Travel routers can often work with these networks, although occasionally you have to authenticate using a laptop or phone first.
Hotels can also impose device limits or have rules against personal networking equipment, so this remains dependent on the property.
A concrete hotel example
Suppose you arrive with:
- two phones;
- a laptop;
- an iPad;
- a streaming stick.
Instead of registering five devices separately, you connect the travel router to the hotel network and connect your five devices to the router.
When it works, that is much more convenient.
It also means your devices are communicating through your own local network rather than joining the hotel's guest network individually.
Case 3: You rent a room or temporary apartment for several months
This is somewhere between the previous two situations.
You may be using somebody else's Wi-Fi, but you still want your own printer, television and computers to behave as a small home network.
Here I would look particularly closely at:
- whether Ethernet is available;
- whether the upstream Wi-Fi signal is strong where you live;
- whether you need gigabit Ethernet;
- how many devices you will connect;
- whether you want VPN functions.
For a two-night hotel stay, extremely high performance may not matter very much.
For six months in an apartment where the travel router becomes your everyday router, I would spend a little more for better hardware.
Five routers worth looking at
Prices move constantly, so treat these as rough U.S. street prices checked in September 2026, not guaranteed prices.
1. Cudy TR1200 1.0 — roughly $45–$70
This is the router that prompted this article.
It is small, USB-C powered, supports WISP and multiple VPN protocols, has a USB port and can create a private network from either Ethernet or an existing Wi-Fi connection.
Current listings I found range from roughly the mid-$40s to upper-$60s depending on the seller.
I would consider it for: a hotel bag, a shared apartment with modest internet speeds, or solving device-isolation problems without spending very much.
I would think twice if: you have fast wired internet and want more than 100 Mbps through its Ethernet connection.
Cudy is the brand name used by the networking manufacturer, which says it was founded in 2018 and produces consumer and business networking products.
2. GL.iNet Opal (GL-SFT1200) — about $40
GL.iNet currently lists the Opal at about $39.99.
It is another compact Wi-Fi 5 travel router and is probably the most obvious budget competitor to the Cudy.
I would consider it for: inexpensive hotel use or basic shared-Wi-Fi situations where you want the mature GL.iNet travel-router software environment.
3. TP-Link TL-WR902AC — roughly $40–$65
This little TP-Link has been around for quite a while and remains widely available.
Current U.S. listings I found are roughly in the $40 to $65 range, although some sellers charge more.
It supports several operating modes and is tiny enough to live permanently in a travel bag.
I would consider it for: straightforward travel use when you prefer a familiar mainstream networking brand.
It is an older Wi-Fi 5 design, however, so I would not necessarily choose it as the main router for a long-term high-speed apartment setup.
4. GL.iNet Slate Plus (GL-A1300) — about $70
GL.iNet currently lists the Slate Plus at approximately $69.99.
This is where the comparison becomes more interesting for somebody living long-term on shared internet rather than merely staying in hotels.
It provides gigabit-class Ethernet connectivity and GL.iNet's VPN-focused router software while remaining portable.
I would consider it for: a temporary apartment, shared building connection or frequent travel where the router gets serious everyday use.
5. GL.iNet Beryl AX (GL-MT3000) — about $99
GL.iNet currently lists the Beryl AX at $98.99.
This is a Wi-Fi 6 travel router with a 2.5-gigabit WAN port, so it makes much more sense when the upstream connection is fast and you do not want the router's Ethernet interface to become the obvious bottleneck.
It is still compact enough for travel.
I would consider it for: somebody who travels regularly but also wants the device to function as a capable everyday router in an apartment or other semi-permanent setup.
So which type would I choose?
For occasional hotel use, I would keep it simple.
The Cudy TR1200, GL.iNet Opal or TP-Link TL-WR902AC may be perfectly adequate.
For somebody who actually lives on a shared building network, I would look more seriously at the GL.iNet Slate Plus or Beryl AX, particularly when the building provides a fast Ethernet connection.
That does not make the Cudy a bad product. It means the use case is different.
A $50 router that solves printer and streaming problems in a modest shared apartment connection may be exactly what is needed.
If the router is going to become the center of your home network every day, spending another $30–$50 can make sense.
Before buying anything, identify the actual problem
I would check these things first:
- Can your devices reach the internet?
- Can your own devices see one another?
- Do you have Ethernet available, or only Wi-Fi?
- Is this your home for the next year, or a hotel for the weekend?
- Does the building or hotel permit personal routers?
- How fast is the upstream connection?
- Is the problem actually isolation, or simply weak Wi-Fi?
That last question matters.
If the upstream signal is poor, a travel router does not magically create a good internet connection.
If the printer itself is configured incorrectly, another router does not repair the printer.
But when the problem is a shared network deliberately keeping your personal devices apart, creating your own small private network can be an elegant solution.
And that is a much more useful reason to buy a router than a specification printed on a box.
The Red @ can help determine whether the problem is the shared network, Wi-Fi coverage, the router or the device itself before you start replacing hardware.
