I contacted VM last week because my internet completely dropped out – no amount of resets or joyful calls to the India call centre fixed it ("have you checked that your device is connected to wifi?").
I won't bore anyone with the details of the incredibly tedious couple of days I spent trying to get answers out of customer support but their solution was to send me a Hub 3. In the mean time, I managed to get the wifi working again by switching to 5GHZ. Not an actual fix because some of my devices don't support it, but better than nothing.
I set it up as per the instructions and waited for 2 hours while it went through the flashing light cycle indicating it was updating. I'm no expert, but the manual said up to 20 mins for the update, I found some people on forums saying up to 40 minutes but 2 hours seems sort of ridiculous? In the end I unplugged it and reverted back to my old router, which is working fine (albeit at a frequency I can't use).
I'm fed up of trying to speak to VM customer support on the phone (same conversation every time that goes nowhere), chat bot support (took 2 hours to reply to a message then ended the conversation?) and twitter ("We're sorry to hear you're having trouble, give us a call on 0345... and we'll get it sorted for you").
Please tell me someone here can help.
