Need Help Configuring Router

A few weeks ago I set up my first streaming device and I want to make sure that things are configured properly for best performance, security and privacy.

I got a router in August 2016 and had no major issues with getting it set up for internet use with the computer.
Later, using this article as a guide, I changed some passwords.

Getting the router and Roku 3 player working well together was a bit more challenging.
Moving the router so that there are no obstacles between the router and the Roku helped with the signal strength shown in the Roku settings.
It fluctuated between Good and Excellent.

After reading MA's article, "How to Improve Your Wireless Network Performance", I assigned unique names to the 2.4Ghz and 5Ghz bands.
Then I was able to select the 5Ghz band from the Roku settings and that provided better performance.

If the signal strength drops to Good, the best solution I found is to turn Off both the Roku and Router, wait a few minutes, turn On the Roku and after it has finished initializing, I turn On the router. Turning the router On first does not work as well. It's been stable the last two days.

What should be done with the router for performance, security and privacy?

The cable connecting the modem to the router came with the modem and has no Category markings. It's the only one long enough until I get replacements.
The cable connecting the router to the computer is a flat CAT 6.

Questions:
Is CAT 6 sufficient for all of the Ethernet cables?
For running a cable from the router to the Roku, is there any difference in signal quality between using a 35 foot versus a 50 foot cable?
Any pros or cons between flat and round type cables?

THANKS!
I didn't want this to be so verbose.

 

Just make sure you have set a very robust passphrase and use the highest encryption (WPA2).

CAT6 is more than sufficient. In theory, the maximum effective cable length for CAT-5 or CAT-6 is 100m (328ft) so no worries with your 50 feet, as long as the cable is not abused along the way. That is, not pinched under a table or chair leg and there are no sharp bends or kinks in the cables. The cable should curve around corners.

I avoid flat cable, especially on longer runs. In traditional round cables, there are 4 pairs of wires. Each pair is twisted along the length of cable, then the 4-pairs are all twisted too. This twist ensures any interference is quickly canceled out - a very good thing.

In flat cable, each pair is still twisted, but then the 4 pairs run side by side, parallel the full length of the cable. Running wires parallel introduces the potential for interference (unwanted fields) to be introduced into the adjacent wire.

Flat cable is often used under rugs and carpets so you cannot see it. I say if you need to run under a carpet, don't. Instead, go through walls, floors, or ceilings, or go wireless.

If you absolutely must use a flat cable, buy top quality cable.

If you are making your own (and I always do), "invest" in a top quality crimper. I wasted $40 on two cheap crimpers and a bunch of ruined connectors and cable-ends before investing in a quality $40 crimper that worked every time. If you will be making a lot of cables, doing it yourself can save a lot of money. Plus, if you need 12ft cable, you can make a 12ft cable instead of buying a 25ft cable and stuffing the extra somewhere. A cable tester is also a good idea.

 

Thanks Digerati

Done. Those settings are recommended in the router setup. The passwords are secure.

I'm in a rented apartment, so options are limited.
The service manager told me last week that because there is another unit above (and below) mine, running a cable above the ceiling is not feasible.

Since you do not recommend putting the cable under carpet, this cord protector seems the best option.

Thanks for the cable info. I don't really like the flat wires any way.

 

If your cable runs go where there is foot traffic, then a cord protector is a good idea. You obviously don't want cables becoming a tripping hazard. Besides someone getting hurt, you don't want your computers or network gear getting yanked onto the floor.

My issue with running cables under rugs and carpets is more about them getting walked on. Even under thick carpet, over time, this will break down the insulation which will eventually cause network connectivity issues.
