Hi Dave,
Looking at what I believe is your account I can see that the Humax is trying to update from IceTV every 2 minutes. This is something Humax PVRs do if they are experiencing an Internet or network issue which is causing the Humax to not receive all of the data it requested from IceTV. This can happen when your ISP throttles back your download speed for going over your monthly data quota, or if there is a problem with the wireless network, including a hardware fault with the USB dongle.
A hot USB WiFi dongle normally indicates it has developed a fault. Other symptoms are that it can connect to the home network but cannot reliably download from IceTV or iView or YouTube etc.
Assuming I am looking at the right account, your Humax is still under it's 2 year warranty so you should contact Humax Australia and they will send you a replacement USB WiFi dongle.
If you purchased the Humax and WiFi dongle form IceTV, you can print your invoice details from My Orders in your account, or email support and we can send you a more detailed pdf version of your invoice:
