Xujing Town, Qingpu. 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.
From a flat that cannot hold a video call to a two-floor office

Signal measured room by room, then APs placed or added so every room works.
Book now
Switch, cabling and addressing checked so file sharing and printing work across the office.
Book now
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
Mesh or multi-AP roaming set up so you move between rooms without dropping the call.
Book now
Unknown devices found and locked out, encryption and firmware brought up to date.
Book nowThe network problems we are called for most, and how we handle them
Line, 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.
Signal mapped room by room. APs added or moved where the walls actually block.
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 run is tested end to end and re-terminated. Most dead ports are a bad connector.
The device list is audited, unknown clients blocked, encryption and password strengthened.
VPN, port mapping and firewall rules configured so remote access actually works.
On-site diagnosis is free and the quote is itemised. Nothing is done before you agree.
Cabling, configuration and placement come first. Most slow networks need a setting, not new hardware.
We work on the connection, not your files. Passwords we are given stay with you.
The same fault returning within 90 days is fixed free of charge.
Final cost follows the itemised quote on site. Nothing starts without your yes
