Wi‑Fi works on the phone but not the PC
Av Verkstedsteamet hos Datorhjälp Lerum, datateknikere og it-spesialister · Oppdatert
When the phone has internet on the same Wi‑Fi but the PC does not, the fault almost always sits in the PC network stack, driver or a blocked profile — not the whole broadband plan. Good news: you can often isolate it in 10–15 minutes. This is the order we use in support before we schedule a home visit.
Quick tests that save time
Connect the PC with Ethernet if possible. Cable works but Wi‑Fi does not: wireless side of the PC or Wi‑Fi settings.
Share a phone hotspot to the PC. Hotspot works: home router profile or Wi‑Fi adapter is suspect.
Forget the network in Windows, reboot router and PC, reconnect with the password. Simple — fixes many half-dead profiles.
Windows: DNS, adapter and VPN
In admin cmd run: ipconfig /flushdns, netsh winsock reset and netsh int ip reset — reboot afterwards.
Turn off VPN and 'smart' DNS apps temporarily. Many show connected Wi‑Fi but block normal traffic.
Device Manager → Network adapters: update or roll back the Wi‑Fi driver. After Windows Update, roll back is often the right move.
Router and bands
Temporarily split 2.4 and 5 GHz. Some USB adapters and older laptops misbehave on a merged SSID.
Check MAC filter, parental controls and AP isolation. The phone may be allowed while the PC is blocked.
Still stuck: we troubleshoot on site in Lerum, Partille and Gothenburg — or install mesh if coverage is the real issue.

Ofte stilte spørsmål
Can you fix Wi‑Fi via remote support?
Yes, often — if the PC can reach the internet via cable or hotspot so we can connect. Book via /en/book. Otherwise home visit.
Do I need a new router?
Not if only one PC is affected. A new router or mesh matters when coverage is poor or the ISP box is old for the whole house.
