After installing fiber, the upload speed is not correct and does not exceed 40 Mbps, while other laptops and mobile devices have 500/600 Mbps. The router is not located near the PC and powerline adapters are obsolete. What can be done?
Unfortunately, given the distance between the router and PC, and the fact that powerline adapters are not an option, it may be difficult to significantly improve the upload speed on the PC. Some potential solutions to explore include using a wired Ethernet connection between the PC and router, upgrading the network card on the PC, or moving the router closer to the PC. Additionally, contacting your Internet Service Provider to check for any potential issues with the connection or router settings may also be helpful. UPSers
