Ports not showing 1000mbps
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Upgraded my internet speed to 1gig. The internet port on the router is showing 1000mbps. So it is recognizing the 1gig speed. I ran a new cat6 cable (25 foot) to my home office to a brand new 1 gigibyte switch. Plugged the cable in port 1 of the router and switch and both are only showing 100mpbs. Unplugged the cable from the switch to and plugged directly into computer which has 1 gig compatible ethernet and ran a speed test and only getting 89 mbps.
If the internet port on the router is showing 1000mbps why aren't the lan ports only registering at 100mbps?

Ok don't know why it would matter but previous cables were wired as 568A, just tested a 568B patch cable and the speed was correct.

Hey Gary,
So I just actually kind of went through the same thing with my home network. Things can be finicky when it comes to negotiating the speed between devices.
When configuring the switch, look for the port-negotiation speed settings. It should be, by default, set to Auto Negotiate. You can force this setting, but it will often cause you to disconnect from the network if the situation is incompatible.
More often than not, it comes down to a bad ethernet cable somewhere in the line, try and check to see if the same issue occurs when using another cable, such as a Cat5e Cable, which is also capable of receiving gigabit speeds. Also, make sure that your are either restarting the computer or the network adapter, whenever you change settings so that your computer can renegotiate with the Switch.

@Riley_S The switch is set to auto negotiate. The laptop with gigibit ethernet and connected to the switch displays as gigibit so I know the switch is negotiating properly. The cat 6 cable was run because the cat 5e cable was performing the same and since it was 12 years old, I thought I would just swap it out since everything else was new. Cable tester says the cable is good. Everything was rebooted from the modem through to the computers.
Everything appears as the Archer AX73 Lan ports seem to be issue.

Sorry for jumping in. Can I have the model number of the gigabit switch?
I'm wondering if the length of the cable could make a difference, please try with a shorter cable if possible to check if it can negotiate at 1000Mbps.
You can try different LAN ports of the AX73.

Did you make the cable yourself or buy it online. If you bought a budget cable online from Amazon or eBay, for example, it is not uncommon for the cables to be poorly manufactured and not truly made to the specs advertised. I have read many complaints about cables advertised as CAT 6 not performing to that spec and performing worse or no better than CAT 5. I agree with the other comment. Speed negotiation problems typically are cable related.

His length should not be a problem. CAT 6 can be up to 328 ft without any issues. I recently ran a 150 ft. CAT 6e cable from my router without any issues. As mentioned in my previous post, I would be more concerned with the quality of the cable. Many cheap cables do not use copper, use low gauge wire, or simply falsify the specs to ripoff unsuspecting customers that may never notice the difference between 100 Mb/s vs. 1000 Mb/s connections.

@Kevin_Z Gigabit switch is Netgear GS308E
Connected 3 separate laptops to router lan port with 3 foot 5e cable. Speed test still 94.8. Wireless speed tested at 719.9
