Low wireless speeds from Deco M4
My ISP recently upgraded me to 1Gb cable broadband. However, I struggle to get above 250 Mbps whether I'm at my PC, connected to a satellite Deco two rooms away or sat in front of the base Deco on my phone.
I'm using my ISP's router in modem mode with a pair of Deco M4Rs.
The base Deco is hardwired to the ISP's router through a 2.5 Gbps port with Cat 6 cable.
My PC is connected to the satellite M4 with Cat 6 cable through the motherboard's 2.5 Gbps port.
ISP modem is in modem mode.
Deco is in router mode.
QOS is set to 1000/1000 with no high-priority devices listed.
I am getting a consistent average of around 950 Mbps when I do a speed test when connected to the ISP's router via Cat 6 ethernet.
I am getting a consistent average of around 900 Mbps when I do a speed test when connected to the base Deco via Cat 6 ethernet.
I went from a 350 Mbps package to 1 Gbps, though I believe that this low-speed problem has been an issue since before the 1Gb upgrade. It's only now that I am on significantly faster speeds that I've realised there is a problem. This behaviour is consistent when using multiple PCs, ISP modems, cables, swapping the M4 units around etc. I feel I should be getting much more than 250 - 300 Mbps across wireless if the base unit is getting 900 Mbps.
Any help or advice would be appreciated, thanks.
