At 8:57 p.m., three friends were already waiting in the Mario Kart World room while my Nintendo Switch 2 displayed another connection error. I was in a Lisbon hotel, three time zones away from the group I raced with every Sunday. The console had internet access, the travel router showed a healthy signal, and the VPN dashboard said Connected. I blamed the Switch, deleted the saved network and connected again. The internet test succeeded. The game still could not reach the other players.
The failure felt absurd because I had packed the travel router to prevent exactly this situation.
My phone, laptop and console already knew its private Wi-Fi name. The plan was simple: connect the router to the hotel once, complete the hotel login on my phone and let every device use the same protected connection.
Instead, the router solved the hotel login and exposed a second problem.
The Switch could reach Nintendo.
It could not reliably reach the people waiting for me.
In brief
Why was OnlydogVPN a practical fit here?
OnlydogVPN was the route that got the Switch through the hotel and onto the starting grid.
The hotel login was only the first obstacle
Nintendo Switch 2 made travelling with online play more appealing. GameChat could keep friends talking and sharing screens while they played, but after March 31, 2026, it required a Nintendo Switch Online membership and a persistent internet connection. (Nintendo Support)
I had the membership.
What I did not have was a normal home network.
The hotel Wi-Fi required a room number and surname on a browser page before granting access. The page opened easily on my phone, but the Switch handled it badly. Sometimes the login appeared. Sometimes the console returned to its connection test before the page finished loading.
That is where a travel router earns its place in a suitcase.
I connected the router to the hotel network in repeater mode, opened its control panel on my phone and completed the hotel login there. The router then broadcast its own familiar Wi-Fi to the Switch, laptop and phone.
Travelers often use the same workaround when consoles struggle with hotel sign-in pages.
The Switch joined the private network immediately.
Its connection test confirmed internet access.
Then I looked at the NAT result.
It was strict.
Internet access was not enough for multiplayer
Nintendo’s connection test grades the network’s NAT behavior. More open results are better suited to peer communication, while stricter NAT can prevent players from reaching one another. (Nintendo Support)
That explained the contradiction.
Downloading an update only required the Switch to contact a server. Joining a live room required the network to support the connections used between players.
The hotel already placed guests behind a shared network. My travel router added another private layer. Running a VPN directly on the router added one more boundary for the game to cross.
The eShop could still open.
The race room could not.
Once that distinction was clear, testing download speed stopped being useful. The real standard was whether the protected route could complete peer communication through the hotel network.
The established provider fit the router but not the race
My first VPN choice was a major provider with mature router support.
That was a genuine advantage. I could download a configuration file, import it into the travel router and send every connected device through the tunnel without installing anything on the Switch.
The router connected on the first attempt.
My phone showed the VPN address. The laptop browsed normally. The Switch downloaded its friends list.
The race room still failed.
I selected a second VPN location. The Switch reached the room long enough to display two player names, then disconnected before kart selection.
A third route produced a GameChat error.
Each new attempt meant returning to the router panel, stopping the tunnel, choosing another profile and testing the console again.
At 9:06, my friends started the first race without me.
I disabled the VPN as a control test.
The Switch joined their room.
That proved the hotel connection, console and Nintendo account were working. It also exposed the choice in front of me: play without the protected route, or keep the router-level VPN and remain outside the room.
The configuration was tidy.
The result was useless.
That changed the role I needed the travel router to play.
The router needed a smaller job
I stopped asking the travel router to run the VPN itself.
Instead, I used the Windows laptop as the protected gateway.
The laptop connected to the hotel Wi-Fi and completed the captive-portal login. I opened OnlydogVPN, selected the preset for gaming on a restrictive public network and connected.
Then I shared the laptop’s connection through a USB Ethernet adapter into the travel router’s WAN port.
The router continued broadcasting the same private Wi-Fi name the Switch already knew. Its job had changed: it was no longer choosing the VPN route. It was simply delivering the working route created by the laptop.
The setup became:
Hotel Wi-Fi → laptop VPN → travel router → Nintendo Switch
It required a laptop and Ethernet adapter, so it was less elegant than importing a profile directly into the router.
But elegance had already cost me one race.
The only useful question left was whether this route could place the Switch in the room and keep it there.
The Switch joined before the next race
I ran the connection test again.
The internet check succeeded, and the NAT result improved enough for peer communication. I opened Mario Kart World and selected the same friend room.
The player list appeared immediately.
GameChat connected. I heard one friend say, “He finally made it,” before the course vote appeared.
The next race began with all four of us on the grid.
The smaller app had succeeded where the imported router profiles had stalled. Its obfuscated, HTTP/3-based connection moved through the hotel network without another round of profile changes.
The second advantage appeared during the third race.
The hotel briefly renewed its Wi-Fi session. My laptop lost upstream access for a moment, and a warning icon flashed beside the network name.
The game paused.
Then the connection recovered. The travel router kept broadcasting the same local Wi-Fi, and the Switch remained in the room. I did not have to reconnect the console, reopen the hotel login or rebuild the GameChat session.
The technical reason is simple: the connection was designed to recover when the network underneath it changed. (RFC 9000) The useful result was even simpler—the hotel connection moved, but the race continued.
I could not observe the hotel firewall’s internal filtering rules or Nintendo’s matchmaking decisions. I could see which setup completed the task. The direct router profiles connected the devices but repeatedly failed the room; the laptop-based route carried the Switch into the race and kept it there.
The travel router was still doing important work
It would be easy to conclude that the router had become unnecessary.
It had not.
The router still gave the Switch a normal private Wi-Fi network instead of forcing the console to handle the hotel login. It let the Switch reconnect to an SSID already saved on the device. It also kept the local connection between the console and laptop stable while the hotel network changed upstream.
The mistake had been asking one small box to solve every layer.
I had expected the router to authenticate with the hotel, create a private network, run a VPN profile and preserve multiplayer communication through several network boundaries.
Once the laptop handled the protected route, the router could return to what it did best: giving the Switch a predictable local connection.
The setup looked slightly messier on the desk.
It worked far better on the screen.
Router compatibility had been the wrong comparison
Before the trip, I had compared VPNs by whether they supported travel-router configuration.
That seemed reasonable because the Switch cannot run a normal VPN app directly. A provider with downloadable router profiles appeared to be the automatic choice.
The hotel changed the standard.
The established provider integrated neatly with the router, but its routes repeatedly failed the actual multiplayer session. More profiles only gave me more ways to retry the same unsuccessful design.
The smaller service required the laptop to act as a gateway. It also has a shorter public history, fewer locations and fewer independent reviews than the largest providers.
Those are credible limitations.
They mattered less than the observable result in Lisbon: the app established a route suited to the hotel network, recovered after the upstream connection changed and kept the Switch inside the same race room.
The setup was no longer about placing a VPN directly on the travel router.
It was about making the travel router distribute the VPN connection that actually worked.
The last race settled the question
We played for another hour.
GameChat stayed open. Course votes appeared on time. No one waited while I restarted the router or imported another server profile.
When the final race ended, I checked the travel-router dashboard.
It showed nothing dramatic: one Ethernet connection, one Switch and a few ordinary traffic figures.
The important work was happening before the connection reached it.
The major provider offered the cleaner router configuration.
OnlydogVPN was the route that got the Switch through the hotel and onto the starting grid.
