I've just bought a 'new' unused Zyxel DX3301-T0 modem/router via auction site. It connects to Plusnet services via VDSL and works well in service, but its firmware version V5.50(ABVY.2)C0 is, I believe, quite out-of-date. The Zyxel Support site does list this device, but the only downloads listed are for documents eg User Manual and Setup Guides....no firmware whatsoever is listed. Does anyone know where I could get the more recent firmwares?
Thanks,
Jack
Update: I've managed to find the most recent upgrade file, plus 2 earlier ones, via this direct link
