Hi @James86potatoo
Welcome to our o2 Community.
First of all, thx to schluej for the great tip. Additionally I suggest that you install our o2 my service app, so you can do a preliminary test. The app then generates an ID that you can pass on to the hotline, so that the technical colleagues can then create the fault ticket directly to check you DSL.
Kind regards
Thank you both very much for helping.
However, i cannot run the diagnosis app smoothly. Everytime when i run it, it takes around 3-5 minutes for diagnosis and asking password etc. Withing that time, my internet connection goes at least once “on and off” for some seconds. As a result, the program always tells me that my connection is okay since it experiences a moment of “ok connection”.
By the way, i notice that the front surface of my O2 router case turn brown when it should be white as usual, which is an indication of overheat. Is it possible to ask for a change of this router?
Best regards,
@James86potatoo
Thank you for your feedback. I'm sorry that the troubleshooting with the app doesn't work, you can of course also contact the hotline without having used the app before. My colleagues there will then check everything with you. If it turns out that the router is broken they will take care of everything else.
Kind regards Matze
