7. Problemų sprendimas
Jei kyla problemų dėl maršrutizatoriaus, žr. šias dažniausiai pasitaikančias problemas ir sprendimus:
- Nėra interneto prieigos:
- Patikrinkite visas kabelio jungtis tarp modemo, maršrutizatoriaus ir kitų įrenginių.
- Iš naujo paleiskite modemą ir maršrutizatorių, atjungdami juos 30 sekundžių ir vėl prijungdami.
- Patikrinkite, ar jūsų interneto paslaugų teikėjo (IPT) ryšys aktyvus.
- Silpnas „Wi-Fi“ signalas arba neveikiančios zonos:
- Perkelkite maršrutizatorių į centrinę vietą, atokiau nuo kliūčių ir trukdžių šaltinių (pvz., mikrobangų krosnelių, belaidžių telefonų).
- Sureguliuokite maršrutizatoriaus antenas, kad signalas būtų optimaliai nukreiptas.
- Consider implementing Mesh networking with additional compatible routers for extended coverage.
- Nepavyksta pasiekti maršrutizatoriaus Web Sąsaja:
- Įsitikinkite, kad jūsų įrenginys prijungtas prie maršrutizatoriaus „Wi-Fi“ arba eterneto kabeliu.
- Patikrinkite, ar įvedėte teisingą IP adresą (pvz., 192.168.10.1).
- Pabandykite išvalyti naršyklės talpyklą arba naudoti kitą naršyklę.
- Forgotten Wi-Fi Password or Login Credentials:
- Refer to the label on the bottom of your router for default credentials.
- If defaults do not work, perform a factory reset by pressing and holding the reset button for 5-10 seconds. Note that a factory reset will erase all custom settings.
