Rang tech support who said my signal was too strong and making the router reset so he turned it down and eventually got it working. (Even though it started to not take any settings if i changed the password or ssid name, which made it go into the continuous rebooting cycle of death.).
Now when i plug in any ethernet cable it makes the router go into a continuous rebooting cycle of death. grrrrr
Phoned again and they are sending a high level engineer out but the soonest is in a weeks time. sigh So i thought i would turn off the wireless and now it works through ethernet so at least i can get online. BQM is all red even at night when i wasnt on line and it should now go normal, but if i turn on the wireless it will go red again.
