I have a problem with using mobile internet on my Nokia Lumia 925. When my wifi is on, everything works as it should. When I turn off wifi, my phone should switch to mobile internet (this is turned on). But this only happens when I'm not in the range of my wireless router.

So for example, I have a wifi connection, I turn it off and I take my phone for a walk in my garden. Then I only have mobile internet when I move outside the range of my wireless router.

Does anyone knows a solution for this annoying problem?

Edit: I have sent the phone to nokia for revision and they say that the wifi chip was malfunctioning. After repair everything works great.

  • What happens if you move out of range and get mobile internet working, then move back in range? Does it continue to work?

  • Do you get the EDGE or 3G or whatever symbol near Network Indicator ? Jul 18, 2014 at 4:24
  • This doesn't match my experience, with a Lumia 1020 running 8.1

It is normal. You have to switch off mobile data if you want your WI-FI to auto-search in range connections. If you keep both active, then your phone will switch betwen them as long as one of them become unreachable :)

    I don't think this answers the question. The OP is asking about using mobile data while wifi is off (but a wifi router is in range), not the other way around. The symptoms described are most definitely not normal.

  • Then a Software update via Zune PC app might help

  • AFAIK the Zune software only works with WP7 devices, the Lumia 925 is WP8.
