Computer yangu nikiunganisha na wifi haikubali lakini kwa cable ya simu yaani tathering via usb inakubali nini shida ?

Hii mara nyingi siyo tatizo kubwa sana—kama internet inafanya kazi kupitia USB tethering lakini Wi-Fi haifanyi, inaashiria kuna shida kwenye upande wa Wi-Fi kwenye computer yako, siyo internet yenyewe. Hapa kuna sababu kuu na namna ya kujaribu kuzitatua:

1. Tatizo la driver ya Wi-Fi

Driver inaweza kuwa imeharibika au imepitwa na wakati.
Jaribu:

Nenda Device Manager → Network adapters
Tafuta Wi-Fi adapter → right click → Update driver
Au uninstall kisha restart computer, itajireinstall yenyewe

2. Wi-Fi imeunganishwa lakini “No internet”

Inaweza kuwa:

Router ina shida
Au IP haipatikani vizuri

Jaribu:

Zima na washa router
Disconnect Wi-Fi kisha reconnect
Tumia “Forget network” halafu uingize password tena

3. IP / DNS issue

Jaribu kurefresh network:

Fungua Command Prompt (Run as Admin) kisha andika:

ipconfig /release
ipconfig /renew
ipconfig /flushdns

4. Wi-Fi adapter imezimwa au ina matatizo ya hardware
Hakikisha Wi-Fi iko ON (baadhi ya laptop zina button au shortcut)
Kama haionekani kabisa, inaweza kuwa hardware imeharibika

5. Antivirus au Firewall

Wakati mwingine zina-block connection ya Wi-Fi

Jaribu kuzima kwa muda uone kama inarudi

6. Router restriction

Kuna uwezekano router ime-block device yako (MAC filtering)

Jaribu kuunganisha simu nyingine kwenye hiyo Wi-Fi kuona kama inafanya kazi

Kwa kifupi:
USB tethering inafanya kazi = internet iko sawa
Wi-Fi haifanyi = shida ipo kwenye Wi-Fi adapter, settings, au router
