Connecting via wifi or usb cable?
First thought is WIFI issues before actual 4g issues - especially with the phone getting faster speeds.
The device will connect to a pc via the supplied USB cable - try this way and see what happens.
As WIFI is a shared resource you may be using the same band as one of your neighbours etc.
The device has functionaility to change the WIFI channel, i would go up in incriments of 3, e.g. 1,4,7 & 11 and see which one got you the best results.
Thanks again. I have tried to change channels but it's hard to see any difference.
I am starting to think that this is a network issue, the RSRP and RSRQ of the modem are poor (-91 and -16) and when I compare them with what I get on the iPhone, it's totally different.
Same issue here, phone get 160Mbps download and AC800S only 2-5Mbps. Tried changing SIM, APN, wifi, craddle, and resetting to factory settings but nothing fixes the issue. Optus support made me change APN 4 or 5 times and doesnt work. I'm only left to think that Optus tower is limiting downlink for modems and I still have 6mths of contract to go...
