Xujing Town, Qingpu, Longyang Community. No internet, Wi-Fi keeps dropping, dead spots, slow speeds, IP conflicts — describe what you see and we send the nearest engineer. We arrive with tools and common spare parts, diagnose first and quote before we touch anything.
Paying is fine. Not knowing what you are paying for is not. This is how we have always worked.
Signal measured room by room, then APs placed or added so every room works.

Runs tested end to end, terminated and labelled, so the cabinet makes sense afterwards.
Book now
Routers configured properly: VPN, port mapping, guest isolation and access rules.
Book now
Unknown devices found and locked out, encryption and firmware brought up to date.
Book nowLine, modem, router and account checked in order, so you know whether it is the provider or your kit.
Channel congestion and interference measured, then the channel and placement changed.
Band, channel and link speed measured. Most slow Wi-Fi is a crowded channel, not the plan.
Addressing and DHCP scope tidied so devices stop fighting over the same address.
The device list is audited, unknown clients blocked, encryption and password strengthened.
VPN, port mapping and firewall rules configured so remote access actually works.
