Many Chinese players living, working, or studying in Mexico City, Guadalajara, Monterrey, and Tijuana run into this problem.
After work in a rented apartment, or after class in a student dormitory, you may just want to play a few China server League of Legends games with friends back home, only to find that the connection is not always stable.
Even with Telmex, Totalplay, or Izzi, rental apartment networks, student dormitory networks, shared Wi-Fi, mobile hotspots, and routing differences across Mexico can still affect real gameplay.
You are in Mexico, but you want to play China server League of Legends with friends back in China.
Speed test websites may show a fast connection, and streaming videos may work fine, but once you enter the game, the latency becomes unpredictable.
Sometimes it is 170ms, sometimes 220ms, and during China-side evening peak hours it may suddenly jump above 350ms. The most frustrating part is that it may not lag all the time — it often stutters right when you are fighting, last-hitting, or using abilities.
In many cases, this is not caused by a bad computer, and it does not always mean the game server is broken. The real issue is often that the connection path from Mexico back to China's game servers is not stable enough.
If you have high ping playing China server League of Legends from Mexico, you should first check three things:
Whether the VPN node itself is congested or routing traffic inefficiently.
Whether your local ISP has an unstable cross-border route to mainland China.
Whether the game server region and your actual network path are not a good match.
If ordinary websites are slow, changing VPN nodes may help. But for game latency, packet loss, jitter, and night-time lag, you need to look at the actual route — not just download speed.
Many latency, lag, and disconnection problems are not necessarily caused by your device or the game server alone.
The key is to understand how your connection actually travels from overseas back to servers in China.
The video below is not intended as a benchmark. Different cities, ISPs, peak-hour conditions, and server regions can produce very different results. Its purpose is to show how overseas connections to China servers can behave under real-world conditions.
Game latency is not just about download speed. It depends on the full path your packets take from Mexico, through your ISP, international gateways, cross-border routes, and finally into the game servers in mainland China.
If any part of that path is congested, unstable, losing packets, or taking a detour, the game may show high ping, ping spikes, delayed abilities, or lag during team fights.
Many ordinary VPNs mainly solve website access or IP location problems. They are not always optimized for game UDP traffic, cross-border routes back to China, or night-time stability.
This is one of the most confusing parts of cross-border routing.
Even within Mexico, different regions, ISPs, broadband plans, and Wi-Fi environments can result in completely different routes.
Your friend in Mexico City may have a stable route with one ISP, while you in Guadalajara, Monterrey, Tijuana, or on another broadband route may be sent through a different international gateway.
So another player's experience can be useful as a reference, but it cannot be copied directly to your own network.
Many players assume that if everyone is in Mexico, the latency should be similar.
In reality, different ISPs may use different international gateways and cross-border paths when connecting back to mainland China.
Telmex, Totalplay, and Izzi may perform differently depending on the time of day, local area, and the China game server region.
That is why ISP information can be just as important as country and location when diagnosing a route.
Many players assume that if they are all in Mexico, latency to China server games should be similar.
In reality, Mexico City, Guadalajara, Monterrey, and other regions may use different ISP exits, international routes, and cross-border return paths.
That is why even with Telmex, Totalplay, or Izzi, different cities, student dormitories, rental apartments, and shared Wi-Fi environments can produce noticeably different latency and stability results.
In general, when the route is reasonably clean, a common playable range from Mexico to China server League of Legends is about 170ms to 220ms.
Latency numbers alone do not determine game quality. A stable 90ms connection often feels better than a route fluctuating between 40ms and 200ms.
Mexico City area: roughly 170ms to 220ms
Guadalajara area: roughly 180ms to 230ms
Monterrey / Tijuana area: roughly 180ms to 240ms
If your ping stays above 350ms for long periods, or if it frequently spikes at night, the cross-border route and node path should be checked carefully.
Stability matters more than a nice-looking number. A stable 190ms is usually better for gaming than a connection jumping between 160ms and 350ms.
For players in Mexico, the key issue is not only local Mexico night time, but also evening peak usage on the mainland China server side.
Local broadband in Mexico, international gateways, cross-border return routes, and mainland China entry points may all become congested during this period.
A normal daytime test does not guarantee good night-time performance. Many game routing problems only appear during evening peak hours.
So when judging a game route, do not rely only on one daytime test. Night-time gameplay is often closer to what you will actually experience every day.
This is a very common situation. YouTube, Netflix, and other video platforms can buffer content ahead of time, so short network instability may not be obvious.
Online games are different. League of Legends is real-time. Your actions, movement, abilities, and team fights depend on small packets arriving consistently and quickly.
That is why bandwidth alone does not equal game quality. A connection can stream video smoothly but still perform badly for China server games if the route has packet loss, jitter, detours, or evening congestion.
You can start with a few simple checks.
Only China server games are laggy, while local Mexico websites, videos, and normal downloads are fine.
The problem is clearly worse at night than during the day.
The game often has ping spikes instead of a fixed high ping.
Changing nodes causes large latency changes, but the connection remains unstable.
If several of these happen together, the problem is probably not just internet speed. The connection path needs to be checked.
A VPN mainly solves the problem of connecting to a node. Game acceleration needs to solve a different problem: which route from your location to the game server is more stable.
Some VPN nodes may look close to China, but their actual exit route may detour, become congested, or lack game traffic optimization, making the game even worse.
For gaming routes, latency, packet loss, jitter, and night-time stability matter more than simply showing a better-looking IP address.
Location: Mexico City, Mexico (Telmex / Totalplay)
Game: China server League of Legends
Daytime: 170ms to 220ms
China-side evening peak: Often above 350ms
Optimized route: Real-world tests have reached around 140ms to 180ms when the route, ISP, and server region match well.
Symptoms: Team fights feel delayed, abilities react late, and ping occasionally spikes.
Diagnosis: More likely evening cross-border route jitter than PC performance or broadband speed limitations.
Not always. You should first check your actual route. If your local environment and ISP path are already decent, you may only need to adjust the node or connection method.
Because speed tests mainly measure bandwidth. Games are more sensitive to packet loss, jitter, and unstable routing. Fast download speed does not guarantee stable gameplay.
Possibly, but not always. During evening peak hours, your local ISP, international gateways, and cross-border routes can all affect gameplay.
Yes. Haipaida first checks your country, city, ISP, device, game, and current latency behavior, then judges whether the issue is more likely caused by the VPN node, cross-border route, local network, or game connection path.
If you have high ping playing China server League of Legends from Mexico, do not rush to change VPNs first.
The real question is: what route does your traffic take from Mexico back to the game servers in mainland China?
If you are not sure where the problem is, you can send us your location, ISP, game name, and current latency.
We can first help you determine whether it is:
a VPN node issue,
a cross-border route issue,
or a game connection path mismatch.
