Bought one of the above from Argos about 6 months ago and all was well with BToW, however I recently migrated to zen and no matter how many times I configured the thing, it still wouldn't let me connect to Zen. I called Binatone, spoke to a helpful gentleman who advised me that I'd need to upgrade my firmware. He gave me the direct links to the download files and I followed the simple instructions (I have updraded kit before).
Now all of a sudden, it looks as though the flash went wrong, and the USB light is blinking on the Modem/Router. I called Binatone again, spoke to same guy who said that flash must have failed and that Argos (where I bought it from) would replace it with no hesitation. Now, I have no box, and I can't for the life of me find the receipt. Surely Argos won't take it back.
