Yes, basically all switch chipsets in the last decade+ have had auto crossover detection. It won't have any impact on speed.
Is a new cable modem helpful?

For a 1m cable, it probably doesn't matter.
They can handle crossed pairs, reversed polarity of one or more pairs-- basically anything except a split pair, which will completely disrupt the data connection even on a cable only a few feet long.
Not saying anyone should leave faulty wiring in place because of this though. Also note that split pairs can test OK on a basic cable tester that tests DC continuity.

Agreed.
Worth noting, while auto crossover and cabling detection is broadly prevalent on inexpensive unmanaged network gear, tolerance for configurations beyond just Auto-MDIX may vary wildly.
Older Cisco gear didn't support Auto-MDIX for quite a stint after it had appeared in the consumer realm, not sure about other manufacturers in the Enterprise space. At that time a lot of the old Cisco boys were hard coding speed and duplex on interfaces still, so resistance to automatic functions has long been an issue.
I don't SSH/Telnet into my router... not that nerdy. Grabbed this grab while doing a speed test, don't see anything too dramatic.
Did both wired and wireless speed tests.
When I first hooked up the Modem I used my old CAT 5e cable and was getting 240 MBPS. Then decided to use the new CAT 5 cable and my speed dropped to 100 MBPS and a red light appeared on the Modem so I went back to using the CAT5e cable.

That's awesome
My ISP, when they used to send out those little Comtrend ADSL modems would send CAT5 cables with only 4 conductors in them, so you sure as heck weren't doing Gig-E.
That cable sounds like it's trashed. Would be interesting to see what a megger (high voltage insulation breakdown) test would show. Though that would probably completely finish it off. Is there at least a pull string in the conduit?

Think so. If we redevelop the outbuilding I'll be running fibre to it. I've been having new home runs made in the main building with CAT6 as spaces are being worked on. It's a slow process as the building is active, so it limits how much can be done at a given time. Security system overhaul is also in the works.
I forgot to mention these cables are only 5 ft long and go directly from computer to modem.That's awesome

Would recommend using fibre designed for outdoor burial/duct use. Running the orange jacketed duplex fibre through that seems like it'd be asking for problems, not the least of which is that it's not designed to handle the stress of being pulled through a few hundred feet of conduit.

Yes, it'll be the same style of outdoor fibre I have running into the building from Rogers, no worries there.
From what I've seen, at least on Comcast they've kept 32 legacy SC-QAM channels and run a 96mhz OFDM block.
Well gang the new modem is in and installed. No measurable speed improvement.
We'll see if, as time goes on, immesurable improvements (aka butt dyno) are noted.
Did get into the new router's internal config, all 16 channels are locked, so... it's them.
At least I'm a little future-proof.

Have you tried the CLI version of speedtest, I find that speedtest.net can give all over the place results because they have so many ads on the page that it slows down the actual speedtest.
Is it a company supplied DOCSIS 3.0 home gateway (combo modem / router / wifi) or something else?Well gang the new modem is in and installed. No measurable speed improvement.
Can you see your connection statistics, especially SNRs and uncorrectable errors?
Have you ran the speedtest with the modem connected directly to the computer without the router?
