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?

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?
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.

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.
Yeah I suspect theres a cable somewhere not playing.
I m ordering new cable for that to see what a problem
And connect it to router directly. You can have problém in Wall socket.
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’.
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?
its cable most likely. try another one.
This just happened to me today lol, turns out my old Dell laptop doesn’t have a gigabit port. Got full speed on Apple TV and new laptop.
99 times out of 100 this is an issue with the cable. Be it the one in the computer or the one in the wall.
Laptop port has problem i figure out
Almost certainly the NIC in the PC. The fact that it’s exactly 100 sounds like a misconfiguration
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
Bad cable probably.
Not sure why this isn’t a more common solution, but check your negotiation settings in Speed and Duplex.
Classic Layer 8 issue
If you terminated your own cables, this is the issue.
