@Tony I've got in touch with them lets see what they say. As this is quite annoying the fact I'm only getting barly a 3rd of the speed I'm paying for.

@Carl I am using the S4 Deco on the latest firmware. I pay for 350Mbps, and have the ISP modem connected to the Deco, when connected directly to the ISP modem. I get over 350mbps, soon as I connect...

@Carl I tried via Wifi and ethernet same result. I've been reading up on the forums, and the S4 seems to be a common issue to reduce the speed from what I've gathered so far. Could be a firmware...

@Carl I have the same problem, when I connect it to the Hub ISP( getting 350mb) when I connect the ethernet to the Deco, jumps to under 100mb. What's the problem? This seems to be a very common...

@Ezuzu I have even updated to the latest firmware, assuming that'd fix the problem, but still nothing. Still crappy speeds around the entire house.

I've followed this as I was having similar issues, but no avail. Is this normal?
