After the motherboard upgrade, internet speed is limited to 100mb per connection.
I recently faced an issue with my MOBO and decided to renew it. I upgraded to the AsRock B760M PG Lightning. Previously, my fiber connection was stable with speeds exceeding 400mb/s. Now it’s capping at 100mb/s. I’ve tried updating drivers from both Realtek and Dragon boards, but nothing changed. I don’t have a clean Windows installation option on my boot drive yet. I switched to a new certified Cat6 Ethernet cable, powered off and on my router and modem, but the problem persisted. Both settings were changed to force 1Gb and Auto, yet speeds remained at 100mb/s. Windows 11 is fully updated as of January 2025. My ISP has been asked about any issues, but since this happened right after the MOBO change, I’m exploring other fixes on my end. Any suggestions?
Typical reason is faulty cable, possibly involving drivers as well.
It was a Gigabyte B660M GAMING X (rev. 1.0) DDR5 unit. I got it brand new around two years ago when it stopped working, so I swapped it in with an Asrock.
Disable IPv6 settings and ensure the Ethernet card is current.
You're looking for a straightforward way to reinstall Windows 11 without going through the usual troubleshooting steps. A fresh install might be the simplest option, but you could also try restoring from a clean backup or using a recovery media if available. If none of these work, consider reaching out to support for guidance tailored to your situation.
