Ethernet Speed at 100 Mbps instead of Gig - Tried all that I could find

On my relatively new Inspiron 5570, I can't figure out how to get the Ethernet speed above 100 Mbps. 

1- Internet service of 1 gig.

2- Cable is new and carries speed of over 800MBps on other laptops 

3- WiFi on the Inspiron (from the same source) is in excess of 300 MBps.

4- The same cable connected via USB adapter is hitting 800 MBps

5- The laptop previously was stuck at 100 until I removed smartbyte and then it was blazing fast. I don't know what happened since but smartbyte is not installed and I can't get it above 98 or so.

6- The adapter status shows the that LAN speed is 100 Mbps.

7- I updated the Realtek adapter with the most recent driver -  10.37.1028.2019

8-  Speed and Duplex on Auto Negotiation

9- The physical pins in the Ethernet port appear ok

What am I missing?

it’s just the limitation of your 10/100 mb ethernet port. Nothing you’re doing wrong here, Dell basically saving a few cents. The 7000 series has a giga ethernet port; the 5000, they kept the 100mb max port. Pretty pathetic in this day and age. 

 

In case it is not the port and on a different system: 

Still not resolved? Use the "Get Help Now" option at the bottom right to chat with a Dell technician right away.

I wasted hours on this because this was the last thing I would have expected. Pathetic indeed.

I agree this is pathetic.  The Latitude systems have had Gigabit Ethernet since at least the D series debuted somewhere around 2003, and here we are more than 15 years later and some systems still have 10/100.  I get that many, possibly even most, Inspiron customers might never use Ethernet the entire time they own their systems, but if that's your viewpoint then just dump the port entirely.  If you're going to keep Ethernet -- perhaps because you recognize that one of the use cases would be people who have very fast Internet connections that can't be reliably delivered over WiFi, at least not in all areas of the home -- then add a proper Ethernet chip so that it doesn't become a bottleneck with such Internet connections!  Giving someone 802.11ac WiFi and 100 Mb Ethernet means that WiFi will in many cases be faster, often significantly faster, than Ethernet.  So the only use case for 100 Mb Ethernet is what -- areas where there's no WiFi or terrible WiFi and only a relatively slow Internet connection?  How many people are in that situation?

And I'd love to know how much Dell is saving in 2019 by skipping out on Gigabit Ethernet.

My reaction was the same when I bought my 5570: 

My solution:

- USB-C to Gigabit Ethernet adapter (~15 USD/EUR), problem solved!

I bought a USB-C HDMI/1 Gb/USB-C port adapter for my "desktop" system i8550 (Cinebench 702) with 3 monitors, 1 Gb ethernet connection and 6 USB ports, pretty cool and works perfect!

I also use a USB 3.0 Gigabit adapter and it works well. But keep in mind the round trip time is a slight higher than the built in 10/100 port. (if you ping using both you can see the difference). Sometimes the difference is huge as 2ms. But I don't know whether this is a problem of this kind of devices or just the brand I'm using.

Wait are you telling me that the new Inspiron 3505 I just bought can't even utilize my full internet speed? It's rated for 150Mbps and I routinely get 300 on my desktop pc, I can hardly crack 90 on this new dell laptop.

 

edit: the spec sheet says wifi could have up to 150 on Realtek and up to 433Mbps on Qualcom, is that theoretical speed as long as my modem can supply it?

Wifi and Ethernet are separate issues.  The wired Ethernet on this model is indeed 10/100 Mbps - not gigabit.

The speed of the wireless module is either 150 or 433 Mbps, depending on which option you have (but note those are maximum values - you will never see either maximum in everyday use).

@Bikergofast  Even 433 Mbps is pretty low for theoretical throughput these days.  Good 802.11ac WiFi cards quote maximum throughputs in the 800 Mbps range or better, and the newer 802.11ax/Wi-Fi 6 cards go even higher.  But as noted, that's WiFi, which is a totally separate network interface from Ethernet.  If your router or whatever device you're using for WiFi can't push your full Internet connection speed to your system over WiFi under whatever conditions such as distance are normal for you, then you may want to consider a Gigabit Ethernet to USB 3.0 adapter.  It will tie up a USB 3.0 port (which can be mitigated with a hub if needed), but they're not very expensive at all.

Thanks, that explains it well. I suppose I have only myself to blame for not digging into it more before buying it. Though, if you look at the spec sheet for the Inspiron 3505 it only says RJ45 for ethernet connectivity, does this automatically mean 10/100 LAN? 

Regardless it's dissapointing in 2021 gigabit isn't standard. 

That model Inspiron isn't even listed on the store page anymore, what gives?
