Don't know if anyone can throw any light on this. I've got a Superhub 3. Last night I was getting 5ghz connection on my phone, no problem with speed. But laptop wasn't connecting to wifi, and the laptop network card only does 2.4ghz. Turns out I couldn't get 2.4ghz on my phone anymore either.
I reset the SH3 and this morning it was still flashing green lights and arrows, no connection. So I reset it again today, this time holding the reset button for 60 seconds whch is apparently the way to do it. After an hour still no connection, still flashing green lights, alternating between the arrows and the horizontal light at the bottom. I called VM tech support and he said unplug it and switch it off, then plug back in and switch on. And they're sending an engineer tomorrow morning.
A few minutes after the call, the lights stopped flashing and I got connected. Then I went into the router settings page to give the 2.4 and 5ghz separate SSID names and passwords like I'd created before the reset. After that, I wasn't able to connect again. Did another reset, still not connecting. Connected my old SH2, still not connecting. So it doesn't appear to be a broken router issue. I've just connected the SH3 again and waiting to see if it'll connect.
It's very odd. Physical connection of the cable is solid, tightened with my pliers. I haven't look inside the box outside but since the cover hasn't come off, I'm assuming the wires are intact, especially since I already had a connection before I messed it up. Anyone got any ideas?
