We are a Sydney-based WiFi, NBN and computer repair service, trading as Sydney WiFi and Computer Repair Center under DOUBLE X NETWORKS. We started operating in February 2025, based near UNSW Sydney, and have grown into one of the more recognised independent network repair services in the Sydney international student and Chinese-speaking community. We also publish guides and case notes on our Google Sites hub, Sydney WiFi Fix Hub — run by the same team behind this site.
我们是一家总部在悉尼的WiFi、NBN与电脑维修服务商，商号为Sydney WiFi and Computer Repair Center，隶属于DOUBLE X NETWORKS。我们从2025年2月开始营业，据点靠近UNSW悉尼校区，如今已成为悉尼留学生群体和华人社区里较有口碑的独立网络维修服务商之一。我们也在谷歌站点 Sydney WiFi Fix Hub 澳大利亚悉尼网络维修中心 上发布科普与案例，背后是同一个团队。
We didn't start as a big company with a call centre — we started by helping people directly, on-site and online, and built a track record one job and one honest review at a time.
我们不是从一家带呼叫中心的大公司起步的——而是从线上线下直接帮人解决问题做起，一单一单、一条真实评价一条真实评价地积累了今天的口碑。

DOUBLE X NETWORKS was co-founded by two partners whose names both happen to start with the letter X — which is where the “Double X” name comes from.
DOUBLE X NETWORKS 由两位合伙人共同创立，两人的姓名首字母恰好都是X——这就是“Double X”这个名字的由来。
15+ years of hands-on experience across smart devices, IT network hardware and software, website development, enterprise office automation, AI tools and marketing — the generalist who can move from an in-wall AP fault to a company website to an automation workflow in the same afternoon.
拥有15年以上实战经验，涉猎智能设备、IT网络软硬件、网站建设、企业办公自动化、AI工具与市场营销——可以同一个下午里，从排查墙面AP故障，到搭建公司网站，再到搭建自动化流程。
5+ years of experience holding an IT-related master's degree, with large-enterprise network IT maintenance experience — specialising in enterprise-level deployment, the kind of structured, documented rollout that a growing office network needs.
拥有5年以上经验，持有IT相关硕士学位，具备大型企业网络IT维护经验——擅长企业级部署，为不断扩张的办公网络提供有结构、有文档记录的实施方案。
Together that combination matters in practice: we understand both the technical side of an NBN connection or an enterprise network, and the very specific, very common problems international students and Chinese-speaking households and businesses run into in Australia that a generic call-centre technician often doesn't recognise on sight. We work bilingually in English and Chinese (Mandarin) as standard, not as a premium add-on.
这两种背景结合在实际工作中很关键：我们既懂NBN连接或企业网络的技术细节，也懂留学生、华人家庭和华人企业在澳洲经常遇到的那些具体问题——这些问题呼叫中心的普通技术员往往一眼看不出门道。中英双语服务是我们的标准配置，不是额外收费的“增值服务”。
My laptop kept crashing with the blue screen of death and the battery had been completely dead for ages. I contacted them for a computer repair and the service was absolutely top-notch. Spent a solid 3 hours sorting everything out.
我的笔记本一直蓝屏死机，电池也早就完全报废了。联系他们上门修电脑，服务非常专业，花了整整3个小时把所有问题都解决好。
I can't describe how efficient this service is. You only need to contact by phone or text message and they'll guide you to quickly connect to the internet. It's worth a try.
这个服务的效率真的没法用语言形容。只需要打电话或发短信联系，他们就能指导你快速连上网络。真心值得一试。
Had some issues with networking and WiFi dropouts. They came out right on time and systematically worked through and resolved the issues. Great service.
