Splitting isn't a good idea. It makes me want to vomit just thinking about it. (I have had to sort out split wiring home installations once too many...)
If Wifi and Powerline are not an option (you may still consider those for those rooms that don't need high speed connections) then your best bet is to use multiple cheap unmanaged switches and daisy-chain them where needed.
Pull the CAT6 cables from 2 or 3 rooms (as many as fit in the conduit) together on 1 switch. Do this in other areas of the house too and run point-point connections between the switches to tie everything together.
Actually this is what I did in my home, because I have only 1 UTP cable going to the attic and nothing on the 1st floor:
- Ground floor: Router has 4 LAN ports. Use 1 for the Smart-TV, 1 for the UTP to attic and 1 for a Powerline adapter. 1 is still free.
- 1st floor: Powerline adapter with a 5-port TP-Link switch giving me 4 wired connections for the bedrooms. (Also got Wifi coverage from the router/AP downstairs.)
- attic: 8-port HP switch (managed) where my gaming rig, NAS, printer and the iMac connect. (And an extra access-point as the Wifi from downstairs isn't strong enough.)
The NAS actually gets 2 ports in LACP on that switch, so the gaming rig can hammer the NAS with 1 Gb/s without the TV downstairs loosing the DLNA connection to the NAS when my girlfriend is binge-watching some soap.
Can you accept using ethernet over power? Also, it's possible (I've not checked) that maybe you can get 'bundled' cables with multiple cables within a single carrier so it's thinner than all the cables individually? Another way would be a number of switches in different but 'close' rooms, however this would make a ugly network (and take up more space/power than actually required). – djsmiley2k TMW – 2017-10-05T13:14:58.013
Do you mean powerline ethernet? Do they work as good as an ethernet cable? Bundled cable would be a no go for me as i can only get them through a chinese website maybe, with no guarantees, long shipping times,lot of hassles with the customs and and ultimately wont be able to fit them anyhow. Can i connect one switch to another with no data loss and how many times do you suppose i can do that? – Ankur Chaudhary – 2017-10-05T13:20:44.280
2@AnkurChaudhary Powerline (the AV1000 and AV2000 versions, stay away from the older ones) are pretty good these days. I'm getting stable 600 Mb/s connections (a set of TP-link AV2000 devices) in my home. Be aware that Powerline performance can vary a great deal depending on wiring quality in your house and nearby presence of electrical disturbances. It is impossible to say for sure whether it works well in a given setup. The onlyl way to be sure is simple to try. – Tonny – 2017-10-05T13:31:23.770
Is powerline better than installing multiple ethernet switches? – Ankur Chaudhary – 2017-10-05T13:35:05.367
