Why Hotel Wi-Fi Won't Connect
Most hotel Wi-Fi problems aren't in the client — they sit at the gateway. The causes below cover the vast majority of cases, ordered by how often they appear, so work down the list from the top.
Captive portal sign-in never finished
After joining the Wi-Fi you first have to enter a room number or verification code in a browser. Until that's done the gateway only lets the portal page through and drops everything else. Start the client first and the handshake packets are simply discarded — you get an endless spinner or a timeout. The right order is: open a browser, finish the portal sign-in, then connect the route. If the portal page won't load while the proxy is on, turn the proxy off and try again.
Ports and protocols restricted
Some hotels only allow 80 and 443, and either throttle UDP or drop it outright. UDP-based protocols fail to handshake on such networks; Hysteria2 and TUIC both run over QUIC and are hit the same way. TCP 443 protocols disguised as standard HTTPS traffic (Trojan, VLESS) establish connections more easily. Keeping a TCP 443 profile in the client before you travel is the least painful fix.
DNS hijacking and double NAT
Hotel gateways often point DNS at themselves, so resolution differs from what you expect: pages load but the client won't connect. Double NAT, meanwhile, breaks anything that needs an inbound connection. Routing DNS queries through the tunnel and running a DNS leak check clears up most of these odd cases.
In-room Ethernet ports and AP isolation
In some hotels the in-room Ethernet port and the Wi-Fi sit on different subnets, so devices can't see each other. Move the same laptop from Wi-Fi to Ethernet and the local-subnet rules in your split routing may stop matching — the connection drops the moment you switch networks. Re-checking the local subnet settings usually restores it.
Authenticate first, then connect
The most common hotel-network failure is doing things in the wrong order: starting the client, then trying to reach the portal. Portal pages often won't load through a proxy, so sign-in never completes. Swap the two steps and most connection failures simply disappear.
How Much Data a Trip Needs: Tiers by Trip Length
Data needs come down to three things: how long the trip is, how many hours a day you're online, and whether you join video calls. Rather than memorizing per-hour consumption, match your trip to a tier so you know before you buy whether it's enough.
| Trip and usage | Suggested tier | Notes |
|---|---|---|
| 3–5 days, mostly email, documents and messaging | Monthly plan ¥9.9 / 60GB | The most common short-trip combination; data resets monthly on your activation date |
| 1–2 weeks, daily video calls and cloud documents | Monthly plan ¥18 / 250GB | Calls and sync drives running at once, with more headroom |
| Long-term posting abroad, large file transfers and remote desktop | Monthly plan ¥28 / 500GB | The largest single tier — for using the routes as your everyday network |
| Only a few trips a year | Data packs from ¥158 / 300GB | Use it up at your own pace, never expires — no monthly renewal |
Monthly plan data resets each month on your activation date, and mid-term upgrades are prorated against the remaining days. Data packs are used up at your own pace and never expire, which suits people whose usage is concentrated in the weeks they travel. There's no device limit: phone, laptop and tablet can be signed in at the same time, with no second purchase needed for a second device.
Before buying, check the traffic stats in the client: note the usage on a typical travel day and multiply by the number of days — that beats guessing. Background traffic from sync drives, system updates and photo backups is the easiest to overlook, so set those to Wi-Fi only or manual sync before you leave.
For a short trip, start with the smallest tier: ¥9.9 for 60GB covers 3–5 days of email, documents and web browsing. Once a trip runs past two weeks with daily video calls, move up to the ¥18 / 250GB tier — steadier on both budget and headroom.
Will Cross-Border Work Apps Run Properly?
Whether an app works depends on what it's sensitive to. Breaking it into four categories is far more useful than asking a blanket 'will it connect?'
Email, calendar and documents
These use fixed ports such as 443, 993 and 465, so they ask the least of a route. The real trap is DNS: resolve to the wrong edge node and attachment downloads swing between fast and slow. Once DNS goes through the tunnel, this mostly disappears.
Video calls
The most sensitive to packet loss and jitter. Meeting apps generally prefer UDP, and once a hotel network throttles UDP the picture drops to low resolution and, in bad cases, the call drops entirely. During a trip, putting calls on an IEPL dedicated line or a low-latency relay does more than switching clients.
Code repositories and package managers
Cloning repos, pulling images and installing dependencies mean long connections and heavy traffic — the risk is a stream that dies halfway. Tools with resume support pick up where they left off; the rest start over. Configure your usual mirrors before you leave and you save half the waiting.
Internal systems, SSH and remote desktop
These connections need stability, not bandwidth. Add your company's internal subnets to the direct-connect rules so traffic doesn't take a detour and internal domains don't get resolved by the proxy into public addresses.
| App category | Main sensitivity | Route suggestion |
|---|---|---|
| Email / calendar / documents | DNS resolution, fixed ports | Direct or relay |
| Video calls | Packet loss, jitter, UDP availability | IEPL dedicated line |
| Code repos / package managers | Long connections, throughput | Relay or dedicated line |
| SSH / remote desktop / databases | Connection stability | IEPL dedicated line |
Browser tabs, sync drives and system updates keep consuming data and connection slots in the background. Pausing them before a call starts works better than upgrading your plan afterwards.
What decides the experience is the route type, not how many clients you install. Put calls and remote desktop on a dedicated line and a relay is enough for repos and documents; cramming all traffic onto one route is the most common performance waste on a business trip.
Pre-Departure Checklist
The list below is split into before you leave and after you check in — follow it and you'll avoid most on-the-spot problems.
- ✅ Install the client and sign in on your own machine before you leave — don't wait until you're in the hotel room to download it
- ✅ After importing the subscription, refresh the node list once by hand and confirm the routes are visible
- ✅ Keep a TCP 443 fallback profile ready in the client
- ✅ Turn on DNS through the tunnel and run a DNS leak check
- ✅ Add your company subnets, NAS and printers to the direct-connect rules
- ✅ Keep the subscription details on your phone so you can restore quickly when you change devices
- ❌ Don't start the client before you've finished the hotel portal sign-in
- ❌ Don't leave global mode as the default — local banks and portal pages will stop loading
- ❌ Don't sign in to the account panel on a public computer
Choosing Routes and Protocols
Route type decides stability; protocol decides whether you can connect at all. Look at the two separately and the choice gets much clearer.
Three route types
- IEPL dedicated line: a fixed path that doesn't go through public internet egress, so it fluctuates less at peak times. It costs the most and suits video calls and remote desktop.
- Relay: an optimized path between entry and exit, with price and stability in the middle. A good everyday default.
- Direct: connects straight to the exit node, so performance follows public internet conditions. Suits downloads and web browsing, where real-time response matters less.
Choosing a protocol
Shadowsocks is lightweight with low overhead; VMess carries a user ID and supports multiplexing; Trojan disguises traffic as standard HTTPS, so it gets through networks that only allow 443 more easily; VLESS is leaner and often paired with TLS-style obfuscation; Hysteria2 and TUIC are built on QUIC and retransmit more aggressively on lossy networks, but they're unusable on networks that block UDP. On a business trip the suggested order is: confirm you can connect with a TCP 443 profile first, then decide by network quality whether to switch to the UDP family.
Writing split-routing rules
The basic order: direct for company subnets and local ranges, direct for the local services you use every day, proxy for everything else. Global mode looks simpler but sends hotel portals, local banks and map services on a detour too, which causes more problems than it solves. Run the rules once before you leave and confirm internal domains resolve to internal addresses.

Quick Answers to Common Questions
Hotel Wi-Fi won't connect — what's the first step?
Disconnect the client, open any http page in a browser to trigger the portal sign-in, then connect the route. If it still fails, switch to the TCP 443 fallback profile.
For a one-week trip, a data pack or a monthly plan?
Look at whether your usage is concentrated in the days you travel. If you only take a few trips a year, a data pack that is used up at your own pace and never expires fits better; if you travel every month, the monthly plan is cheaper.
Does unused data in a pack get wiped?
No. Data packs are used up at your own pace and never expire — that's exactly why they suit low-frequency travel.
Calls stutter — is that not enough bandwidth?
More often it's packet loss and jitter, not bandwidth. Switching to an IEPL dedicated line or a low-latency relay helps more directly than upgrading your plan.
What if the company intranet is unreachable?
First add the internal subnets to the direct-connect rules, then confirm DNS isn't being handled by the proxy. Some internal systems only allow specific egress addresses, so check the policy with your ops team.
Choosing a business trip VPN comes down to three steps: first get connected with a TCP 443 profile, then pick a data tier by trip length so you have enough, and finally assign routes by app type so things stay stable. Beyond those three steps, the pre-departure checklist matters more than any spec.
