I have cat 6 cabale and router and laptop have gbps port and also my network provider support gbps speed still my network shows me its 100 mbps any solution?

check for damaged pins in ethernet ports. gigabit uses 4 pairs and 100 meg uses 2 pairs so maybe a bad connection in one of the ports.

Test patching directly into router, not via internal cabling.
Test different cable.
Test with different laptop.Just for fun: test WiFi, preferably 5 GHz. If that nets you more than 100 mbit then your router/ISP is the issue.
Also, what do you get when testing on e.g. Speedtest.net?
What are you hooking your laptop up to? Make and model? And can you verify in devicemanagement that your laptop has a gigabit NIC?
Yes my nic has gigabit support i check alredy
Yeah I suspect theres a cable somewhere not playing.
I m ordering new cable for that to see what a problem
Good idea. Check all that may be able to influence the speed. I spent an hour scratching my head about this same problem once and it was a Cat5 (fe) cable between my switch and router - I kissed it because I kept looking at the patching on the port. If cables test out fine then go ‘upstream’.
And connect it to router directly. You can have problém in Wall socket.
It’s likely just a driver update. I had a similar problem and that fixed it
Your laptop probably has a broken ethernet port.
I have a ROF zephyrus laptop and for some reason it’s gigabit Ethernet card started stating it was 10/100 and nothing I did would get it off FE.
It has WiFi 6 and I use a thunderbolt dock that has Ethernet and because of that I’m not that worried, but ports can and will just go bad or drop down to FE.
It’s your NIC
- try another cable - make sure it is CAT6 or better CAT6A
- Have a look if (even if it says so) Auto-MX is active - if it is, set connection speed manualy to 1gbps
- If there is another Port on your Providers Router, go for it
In 2. What is auto mx ? Are you talking about properties of realteck drivers?
Properties of your NIC - but also on the router - if not possible (stuff from ISP)try another port on your router first if it has more than one “Lan ports”
I already tried all the port s and also change nic settings
If the cable is good and is a direct connection between device and switch/router, then it’s a hardware issue. Gig requires all 4 pairs, 100Mbps only 2.
Are you paying for gigabit speeds?
Almost certainly the NIC in the PC. The fact that it’s exactly 100 sounds like a misconfiguration
I’ve seen 5-6 Asus Zephyrus laptops refuse to connect at anything other than 100Mbps, even after turning off the auto-neg and setting it to 1G, they would still connect to the switch at 100M.
This has all been within the last 6 months, I wonder if they released a broken driver for whatever NIC they’re using.
Even if you have a cat 6 rated cable depending on the cable itself, the NIC and your router will validate if it can reach 1GB speeds, if the twisted pairs in the cat 6 cable are degraded in anyway then the NIC and the router will negotiate to a speed it can support, which may be your issue here. I would try using another cat 6 cable you know is good to validate if its just a bad cable or not.
or lets say ha
Not sure why this isn’t a more common solution, but check your negotiation settings in Speed and Duplex.
