I am doing major reno in my house and intend to hack the walls and put in ethernet cables in it, running through walls until my office/gaming room. Choosing CAT7 cable as it's more future-proof as I don't want to hack the wall again within 10 years (if nothing goes wrong).

I have not used CAT7 before (currently on CAT6), the CAT7 is using GG45 not RJ45. So can I still use the cable normally and connect it without issue to my TIME modem and router?

Anybody with experience on using CAT7? Do shed some light pls.

Note: prefer using cable not wifi due to more stable connectivity

Not sure what you mean by GG45, but I am using UGreen Cat7 flat cables for my routers and to my PC, and on Unifi, so far no issues, I just changed one of my old Cat5e cables to Cat7 as the connector head sometimes disconnects. Now no problem. xD If you want cheaper for inside of walls use rounded cables, easier to pull, flat cable a bit hard to pull, but no doubt nice finish. Looks premium and neat, provided your guys know how to pull properly and neatly.

Well from all my googling, it mentions cat7 is using GG45 connector instead of RJ45 (although with backwards compability). That is what made me confused and don't want to make wrong decision. Once the cable is installed into hacked walls, i die if it's a wrong decision.

xD I think it should be ok, i read the info a bit on GG45, basically its just a newer connector but they configured it in a way to follow RJ45 slot, which means backward compatible, i think? lol. If you're worried you can just get Cat6 cable, no worries on that.. xD

Add in Fiber Cable too! Maybe you change your mind in future each room has own fiber? Hehehe..

FYI in europe, when they put wiring, it's covered in pipe. meaning the wire would be inside the pipe…therefore, if you would like to change or update the cable/wire, you can pull them out and just push the new one in..there, u dont need to hack down the walls

That is if from 2nd storey down to 1st right?

Mine is an apartment. With the starting point at living room, have to go through ceiling area, pass a toilet and finally reach the room. Many zig zag. I don't think a pipe can do this.

Yes, you can. If zig zag is your concern then put a rope as you pull the old wire out then use the rope to pull the new wire in.

isnt apartment have single phase power can use powerline adapter? even 3 phase power can supposedly work and it will more likely to work in apartment than anywhere else

from brief reading, you can connect CAT7 to "older" RJ45.
only problem is you wont get 10 Gbps if more than 60M.
But kinda doubt you need that kind of speed

Once in future you need higher speed, then you can change the head/connector to GG45 to enable it to go up to 10 Gbps

Actually can. You have to discuss and plan it out with your contractor. Using pipe is better because you can replace the cable in the future.

There's no compelling reason for Cat7 or Cat7A cabling. If you can buy Cat 7 cable on the market now, they are likely very old cables that has been sitting in some warehouse for years
Cat6A supports 10G ethernet up to 100m. If you need to move further up in speed for future proofing, you should install Cat 8 cables that supports 25G/40G, but it is only for up to 30m, for data center applications.
If you are going for Cat6A cable, I would recommend installing the shielded version of Cat6A, rather than UTP. Make sure the jacks, panels and patch cables are all Cat6A shielded. BTW, Cat6A uses RJ45.
