I'm Wired 5E Can I use the 2.5 ports?

Same. I use 5E for several 10G runs about 25 - 30 ft in my house and have had no issues with my NetGear switches that have 2 10G ports for interlink.

did not know 5e was any higher than gigabit... Cool

Just old plain 5 Can do more than gig as well.. I did a test while back when I found an old just cat 5 long patch cable 25 ft.. in one of my drawers I was cleaning out, sick of people saying you need 6 for gig, etc.. The gig standard clearly stated run over just 5..

I took a picture of the cable showing it just 5, and my iperf test showing 2.37 gig over some usb nics to my nas.. And posted it, not sure if was here, or other forum - after someone saying you needed 6 for gig..

Humble Cat 5e for the win:

And here I thought you needed CAT6a, holy water and the blessing of 2 priests and the pope to do 1Gb...

Also CCA CAT6 doing PoE 1Gb over 60 feet no issues... A rodent chewed the CAT5 doing the same job. CCA may be evil, but it does work on a budget.

overkill likely but anyway can I use my existing Cat 5E

But it is then for a longer time period of usage!

cabling from the 2.5gb ports on the 8200 for gigabit internet?

In many cases this will be not the problem, but if there will be
problems "occurring" you may be able to shorten down or
prevent them from the zero (start) point by using the "right"
equipment, following the given standards. As an example;

• Home network will be able to get the problems fast out
  Often you try out and if something occurs you change it

• Business network you may search for ever the failure!
  You follows the "standard" and don´t get any problems
  So you may narrow down here to a minimum of failure
  points you may have to search.

hahahah - yeah from some threads on the internet you would get that impression..

Indeed - usually from those who only get as far as reading the numbers off the side of the cable.

Electrically there is zero difference between a quality Cat5e cable and those with much bigger numbers.

When you run multiple ethernet cable bundles thicker than a man's chest, running near RF-spewing devices, over and under power cables, at maximum length plus the stranded patch cables; the science as to why the higher categories need enhanced EMC/EMI & mutual and co-channel interference mitigation (to preserve the higher frequencies used) makes a whole lot of sense - especially so for certified installations.

Once you step into the benign RF environment of a small office or domestic house, with the shorter distances and orders-of-magnitude reduction in cable density, those additional mitigation measures do nothing but make the cable thicker and more difficult to work with. I'm more experienced in the high RF environment with certified cable runs and the heavy use of fibre. I don't do it at home though!

I have a small office and I couldn't even get 10 gig to work over 10m of shielded cat5e
I replaced the cables with shielded cat 6a and it still keeps dropping back to 5 gig
This is only two cables in the run.
I have 24 cat5e running to the main office and they do 2.5 gig no issues.

Thanks

Shielded cables can be another can-of-worms if not fully understood.

Try disconnecting one end of the shielding or try unscreened cable.

@RobbieTT

I tried all of that already, I'm just going to run fibre instead when I get time.
Will make it future proof for higher speeds when I need them
