nothing showing up on my devices and no wireless light on my the router. Anyone got any suggestions to fix it?
Assuming a factory reset doesn't resolve the problem, then you've just experienced the downside of Billion routers - they degrade and die! Usually wireless becomes flaky and then doesn't work, then random ADSL disconnects, then router reboots/hangs, then problems booting up.
I have two dead 7404VGOX routers on my bookshelf that have both separately gone through all stages of degradation (both been behind expensive surge protectors too), as well as an earlier 7401 model. Rule of thumb is that if you get a Billion router then you should get a separate wireless AP upfront and then be ready to replace the Billion after about 2 years anyway.
Such a shame, their routers have such great features and are a pleasure to use in the first year.
