FAQ
Frequently Asked Questions
Why is my WiFi so slow even with fast broadband?
Common causes include poor router placement, interference from other networks, outdated equipment, too many devices, or using the wrong frequency band. We diagnose the specific issue and fix it.
What's the best way to extend WiFi to my garden office?
Options include mesh WiFi systems, powerline adapters with WiFi, or a dedicated access point. We’ll assess your property and recommend the most reliable and cost-effective solution.
Should I use my ISP's router or buy my own?
ISP routers are often basic. A quality third-party router or mesh system usually provides better performance, range, and features. We can advise on the best option for your needs and budget.
Can you help with business WiFi for my office?
Yes, we set up business-grade wireless networks including access points, guest networks, VLANs, and security. We can handle small offices to larger commercial premises.
How do I get WiFi in rooms with thick walls?
Thick walls block WiFi signals. Solutions include mesh systems, powerline adapters, or strategically placed access points. In extreme cases, ethernet cabling with wireless access points is most reliable.
Can you help secure my WiFi network?
Absolutely. We configure strong encryption (WPA3 where supported), unique passwords, guest networks, and can set up parental controls and device filtering.
