Basic switch....should I upgrade?

I covered my Netgear switch and plug in 3M EMI/RFI shielding absorber, used the filters below on the ethernet cable and put a choke of on the cord from the wall wart.

DX Engineering DXE-ISO-PLUS-2 - DX Engineering ISO-PLUS Ethernet RF Filters

Ethernet EMI Filter, Patent Pending, RF Common Mode Choke, Inline Coupler EMI Filter, GbE, Double Female RJ-45, Cat 5e, Cat 6 Compatible, Pair.

I had the choke and absorber paper left over from another project.

@fredrik222 seems to be the only one who knows what he is talking about.

An Ethernet switch either works completely & flawlessly or fails miserably.  There is no in between.  Since cheapish switches are designed to mostly work in 1 gigabit range, unless you exceed the 802.11 specs they ALL work, for them, audio level speeds is a walk in the park.

Unless there is something electrically wrong with the switch when you first use it, a different power supply will NOT make a difference.

Keep your money and simply buy a $30 switch.  It will be MORE than adequate.  Just make sure that its existing power supply actually works and make sure the wiring you add is at least category 6 compliant and you will be fine.

@cakyol Dude.....This is team USA; everyones knows what they are talking about. (Young man you are no better than your father and he was no better than his father. Bet the internet doesn't know that one.) Seriously I have benefited a lot thanks too many.  Hans Beelhuysen says one thing someone else says another. Ok. Yup. It's everywhere. Here the pervasive generosity is tops. 

I just dig learning about this stuff and like many like my gear (a lot of watch and car folks here too I'd wager) and refining and/or just switching it up. Your honors, my room is the weakest link but that a non starter w/ you know who.

@sns Bingo! That mangled blue junk from the modem to the router could use an up grade. While I'm at it will also get power lines away.
