Dear Sir/Ma'am   I have been using the TP Link Archer VR1600 modem for a year or so now. Over this time it has provided us an NBN connection that works well about 60-70% of the time but regularly crashes and the WIFI it produces has intermittency problems.   The WIFI will cut off connectivity to our mobile phones once a day or more. The ethernet connection is more reliable however it regularly drops out (5-10 times per week).   A family member who is also a TPG customer used to have the TP Link Archer 1600 also.
