Any practical wire to get close to 1000Mbps speeds over wireless with running cable?

Any practical way to get close to 1000Mbps speeds over wifi?

Hi, first post in this sub, hello!

I've just upgraded from a 600Mbps to 1Gbps on my internet service. I've tested at the router by plugging in ethernet and get very close to the advertised speed.

I'm interested in getting the best possible speed from my home office which is located approximately 8 metres away - and has 2 fairly thick walls in between.

Currently I have the following setup :

Living Room( Cable modem <-ethernet-> Deco M5) <-wifi-> (hallway Deco M5 in cupboard <-ethernet run through gap in floor space ->(Home Office - 8 port switch -> PC).

With the current setup I get around 400Mbps to the PC.

I'm definitely not upto speed on recent wifi - are there any products/standards on the market which might allow decent increase in speed?

If not I'll just bite the bullet and run some conduit/cable from the living room through to the hallway and stick a switch in the cupboard.

Update

There was a happy ending to this, the internet cable came into the house into the cupboard I wanted to move to and there was a splitter on the line - with coax fed through to the living room.

I was ultimately able to move the cable modem from the living room to the cupboard and from there connect directly to the switch in the home office (via a 2 ethernet port deco).

I'd tried this previously but couldn't get it to work. I think last time I was either to inpatient with the modem or there was an issue with the assortment of connectors (including multiple splitters) I had to use to make me things connect.

Living Room( Deco M5) <-wifi-> (hallway modem <-ethernet-> Deco M5 )<-ethernet run through gap in floor space ->(Home Office - 8 port switch -> PC).
