First post in this community - I have read many threads on this topic but they all seem to be quite specific. I hope I haven't caused too many sighs posting on this topic again!
I am in the UK, using the latest Virgin Media 'Hub 3.0' router/modem with WiFi disabled and DHCP enabled. It's in router mode, not in modem mode as I have other devices plugged into it. I'd prefer to keep it that way.
I have connected the three Deco M4s I received in the pack as per the instructions. I have put that in router mode rather than AP mode as I'd prefer the Deco's to do DHCP for all my wireless devices around the house.
It seems to have worked and I have wifi throughout the house and all my devices have connected to the new network without any problems.
The thing is, it's much slower than the network that it replaced (2x ASUS wifi routers connected together via Ethernet and spaced around the house with one in AP mode).
I'm also getting pings around 5-10ms whereas I was getting 3-4ms with my last network. Additionally, I am also getting occassional high pings (200ms+).
I have a 500Mbps connection and it usually pulls around 450-550Mbps (down) and 50Mbp/s (up) from a wired connection directly to the router.
I have done a bunch of testing throughout the house and I'm getting around 20-30Mbps on a bunch of different devices.
Sitting 6ft away from the 'master' Deco M4 (which is connected via Ethernet to my router) the maximum I get is 60Mbps from my wifi devices.
One device I am testing on is a Samsung S20+ which I am sure can transfer more data than that.
My laptop has a Realtek 8822CE Wireless LAN 802.11ac and is reporting that it's capable of transferring data at 866.7Mbps. It can also only transfer at ~60Mbps. (Windows 10 and the laptop is 8 months old, if it helps).
As well as slow speeds, my laptop and other devices don't seem to 'seamlessly roam' at all. In fact, my laptop will cling to the first node with all it's life (even to the point where I have almost zero wifi and basically no connection at all) and a minute later it'll update and change to full bars, obviously connecting to the new node right next to me. Literally a minute. Most of the time it's just easier to disable wifi and renable. But hardly seamless. It's the same with my Samsung device, but a little bit faster.
I'm using speedtest.net to do my testing - which again, shows 500Mbps+ from a wired connection.
In summary, either I've set this up incorrectly, or it's definitely NOT doing what it's supposed to be doing! Any help would be hugely appreciated. Thanks in advance.
Edit: Seems that all the M4 nodes operate on the same channel - no idea why, doesn't seem to make sense to me.
