You could also read my last post. I am happy to take the advice of Computer Science graduates who agree with me.

I'll bow to the almighty wisdom of a comp sci graduate.  I'm only a humble chartered electronic engineer whose day job is communications and network engineering.  I'll remember to drop a few catchwords like ARPing next time though - thanks for the tip

One of the best things about the Internet is that it allows everybody to voice their opinion while one of the worst things about the Internet is that it allows everybody to voice their opinion.

 

I sometimes read with horror some of the pseudo science stated as facts in some of this forum's threads.

..........and if you ask someone much more knowledgeable than me they will tell you that separate cables definitely better for buffering, interleaving and arping.

 

 

As someone with a Bachelors of Comsci Majoring in Network and Software think i can be valid in saying...

 

your argument above makes you look, terrible..

 

 

 

There are solid reasons running multiple wires is a good idea that don't need catch phrases thrown at.

 

 

 

Hope 10G doesn't come out anytime soon, you would be limiting your gateway down to only 1G there! such a bad bottleneck.

I don't understand those terms myself. I was just trying to pass on what I was told to back up my assumtion that running multiple cables would usually be better than running one.

I just wired my son's new house.

 

We have the router centrally located (above the range hood in the kitchen) with 4 Cat 6 cables going back to the (steel) data cabinet in the garage.

 

The ONT is also in the data cabinet so you need a total of 5 Cat 6 cables (one in, four out)

 

 

I know what my rangehood looks like after a couple of years, not a good place for anything you don't want to be covered in both grease and moisture.

 

Also why would you run 4 cables to the cabinet when you could put your critical equipment in the cabinet and use ethernet to connect all wifi access points around the house with just 1 cable per access point. You could even use POE to power each access point from the cabinet without extra cables, so no need to mount it in the kitchen.

Yes but the multiple cables are intended for multiple devices, so perhaps one for the wifi, one for the TV, one for the phone, one for the chrome-cast, one for the computer, etc etc. The cabinet is the centre of the network so the modem and switch go in the cabinet unless you are short of internet outlets around the house.

Just to sum up what I did:-
We have RJ45 sockets around the house wired back to the data cabinet.
The modem/router/4-port switch is in the centre of the house where the wifi works to all points of the house.
I made the debateable assumption that if 4 or less wired devices are connected then using 4 Cat 6 cables to the patch panel would be better than using 1 cable and a switch.
I am happy to be corrected but I am also happy that it is done, did not cost much and works fine.

my question is could your router/switch actually route/switch full speed on all its ports? on one port maybe, on all ports not likely.

Routers with builtin switches normally use a standard switch chip for the switch ports.  So, yes, the traffic between those ports will be full 1 Gbit/s speed.  Only the traffic going to or from the WAN port to the ISP will be slower.  So it makes excellent sense to connect all four of those switch ports to the cabinet if there is no other switch.  Alternatively, put a separate switch in the cabinet, and just one Gibit/s connection back to the router.

Only thing I found was that some routers try to be smart and tell you what port things are on by managing the switch port, and they do it badly like the netcomm with its famous cant bridge between ports sometimes problem.
