Slow speed with Giga switch - help?

Slow speed with Giga switch - help?

I have 1 Gigabit switch connected to the ARRIS TG1682G modem (via short Cat5e cable).  The speed of the computer (using Xfinity speed test) attached to that switch (long cat5e ethernet cable) is ~200 meg (download) as promised.

 

I have a long Cat5e cable running from the ARRIS TG1682G modem to another [different] Gigabit switch upstairs (just updated from slow switch).  When I run the same test (using Xfinity speed test) I can only get ~92 meg (download).  (This  is the same speed as the older switch.)

I have restarted everything and nothing is eating bandwidth while I test.

 

I am not sure why so slow..... thoughts?

Silly me!

 

The short cable from the switch to the laptop was the issue. 

It is only a Cat 5 (not e) cable.

 

I had another shorter 5e (to other PC) and swapped it and now I see the 200+ speeds!

Hmmm... Perhaps there is a problem with the "long" ethernet cable that goes "upstairs" ?

It's a few years old and 5e.
Figure that supports giga speed?

No kinks, etc....

 FWIW, I have read a lot of info in the past about cat 5e and cat 6 cables being mislabeled fraudulently....YMMV.

 

Maybe there is a broken wire(s) that you can't see ?

This is a belkin cable.
Cable is in the wall but I still get 95meg so it must be ok.
Would length impact speed?
I think it is 75 feet.
I may swap switches to see what happens.
