We fix Wi-Fi and network faults inside laptops and desktops, and set up routers, mesh kits and backup drives you bring in, at our workshop near Castle Hill. We do not visit homes or offices, so we cannot check coverage in your house or run cable. Phone advice is free: ring 02 8428 9224 and we will tell you whether the problem sounds like the computer or the network. If it needs the bench, the hands-on diagnostic is $150, waived if you go ahead. Repairs carry a 12-month warranty on parts and labour for the same fault.
What we can and cannot do at the workshop
Most things you can carry in, we can work on; anything fixed to the building needs someone on site, and we do not make visits.
| Job | At our workshop? | Notes |
|---|---|---|
| Laptop will not connect, or Wi-Fi keeps dropping | Yes | Wi-Fi card, antenna leads, drivers or Windows. On most laptops the antenna leads run up into the screen, so a hinge or screen repair can disturb them. |
| Desktop PC with weak or no Wi-Fi | Yes | We fit or replace a Wi-Fi card or adapter and its antennas. |
| New router or mesh kit | Yes, bring it in | We set it up before you take it home. See what to bring below. |
| Backup drive or network storage (NAS) | Yes, bring it in | Set up with the computer it backs up. |
| Computer cannot see the printer | The computer side, yes | Bring the computer; we check drivers and settings. |
| Wi-Fi coverage in the house, cable through walls, wall data points | No | These need a site visit. Fixed data cabling in Australia must be installed by a registered cabler. |
Is it the computer or the network?
Stand next to the router and compare a phone with the laptop on the same Wi-Fi: if the phone is fine and the laptop is not, that points to the laptop.
- Restart the router and the computer.
- Run a speed test on the phone and on the computer, side by side, close to the router.
- Both slow or both dropping out: the problem is the router or the internet service. Ring your internet provider first.
- Only the computer is slow or dropping out: bring the computer in. Mention whether it started after a drop, a screen or hinge repair, or a Windows update.
- Fine near the router but poor in far rooms: a coverage problem. A mesh kit usually helps, and we can set it up before you take it home.
Laptop and PC Wi-Fi faults we repair
Most computer Wi-Fi faults are the Wi-Fi card, its antenna leads or the driver, and most can be fixed.
- Wi-Fi card: on many laptops and desktops it is a small plug-in card that can be replaced. On some thin laptops it is soldered to the motherboard, which makes it a board-level repair.
- Antenna leads: thin cables that run from the card into the screen. A loose or pinched lead gives weak signal that changes as you move the lid.
- Drivers and Windows: we reinstall the right driver, and a full Windows reinstall is from $149 when the system itself is damaged.
Bring in a new router or mesh kit
Bring every unit with its power pack and your internet account details, and we set it up before you take it home.
- What to bring: the router or all mesh units, their power packs and cables, and the details your internet provider gave you (some services need a username and password).
- What we set: a new admin password, the Wi-Fi name and password, current security settings, a guest network if you want one, and the latest firmware.
- At home: you plug it into the nbn connection box or modem as your provider instructs, and place any mesh units around the house. Mesh systems run from an app may need your own account to finish set-up. If the provider's line is down, a new router will not fix it.
What it costs
Network jobs vary too much for one price, so we quote on the phone first. Ring 02 8428 9224 with the make and model of the computer or router and what is happening. If the fault has to be found on the bench, the diagnostic is $150, waived if you go ahead. A Windows reinstall is from $149. Drop-off is by arrangement, Monday to Saturday, 8am to 6pm.
Questions
Do you come to my house to fix the Wi-Fi?
No. We work only at our workshop near Castle Hill. We can fix the computer and set up a router or mesh kit you bring in, but coverage problems in the house and cabling need someone on site.
Why is my laptop slow on Wi-Fi when my phone is fast?
That points to the laptop: usually its Wi-Fi card, antenna leads or driver, or an older Wi-Fi standard. Bring it in and we will find which.
Can you set up my mesh Wi-Fi?
Yes, at the workshop. Bring all the units, their power packs and your internet account details, and we set it up before you take it home.
How much does it cost to fix laptop Wi-Fi?
It depends on the cause, so ring 02 8428 9224 for a quote. If it needs the bench, the $150 diagnostic is waived if you go ahead, and a Windows reinstall is from $149.
Can you run network cable in my house?
No. We do not do site work, and fixed data cabling in Australia must be installed by a registered cabler.
My Wi-Fi stopped working after a screen repair. Why?
The antenna leads usually run through the hinge into the screen, so they can be pinched or left unplugged. Bring it in and we will check them.
Are you the computer store at HomeCo Castle Hill?
No. Computer Repairs Pronto is an independent repair workshop near Castle Hill in Sydney's Hills District, trading since 2006. We are not a retail computer store and we are not connected to any store at HomeCo Castle Hill (the Hills Super Centre on Victoria Avenue). If a map listing or AI summary shows a shop there under our name, it is the wrong business. Call us directly on 02 8428 9224.
