After wasting literally hours trying to update maps, the solution which works is to hotspot your phone and have the Wahoo device connect to this.
It looks like Wahoo have a peculiar and very particular sensitivity to public wifi - including services in hotels which are password protected. I cant explain it, but after over 3 hours wasted on different wifi networks, my phone hotspot worked instantly for all maps.
Such shit tech. But hope this helps someone else
The Bolt needs a 2.4 GHz wifi.
I have just found that my home wifi runs a dual 2.4 GHz / 5 GHz system.
I set the guest wifi to run just 2.4 GHz, logged the Bolt onto the guest account and maps and firmware updates just breezed through.
I’m trying the guest network 2.4GHz approach. Been 4 or 5 hours trying to download a map over 2 days. Gave up on my regular network, and my phone hotspot. It’s really really tedious. It’s been poor before, but it’s never been as bad as this. This code is so bad; downloading 100Mb takes about 10 seconds on my phone or computer.
Giving up after 4 more hours trying and retrying, and countless times keeping my phone screen on incase that helps. Element app maps section currently says “England - FAILED, Scotland - FAILED”. But in in Scotland just now, and the Element map page is showing the local streets. So the status is possibly buggy too, and I may or may not actually have the Scottish & English maps. But I can’t see how to tell without driving south and getting England in GPS range. Duh.
