Issues with slow WiFi on a new PC build might indicate a faulty motherboard.
Issues with slow WiFi on a new PC build might indicate a faulty motherboard.
I recently assisted my friend in assembling his initial PC. The project went smoothly, benchmarks performed well, but the WiFi encountered significant problems. Initially, after booting up, the internet connection functioned adequately (though not thoroughly tested), and we managed to download the necessary drivers and BIOS updates to bring everything up to date. After completing those steps, we observed the internet speed was notably slow—down to 0.7MB and up to 3.5MB. This falls short of the expected 60MB download and around 5MB upload rates. His phone also showed similar performance issues, consistently reporting slower download speeds. When the PC was connected, other devices experienced delays, with both his phone and laptop showing download speeds exceeding 1MB. Turning off the PC resolved the issue immediately. So far, we’ve tried reinstalling/reinstalling the network driver without success, upgraded Windows at a gradual pace, and noticed improved speeds once the update arrived. Then again, after the latest Windows patch, performance dropped again. We’re now weighing options like clearing the drives or a fresh Windows installation.
The system specs are:
- Processor: Ryzen 7 1700X
- Motherboard: Gigabyte B450 Aorus Pro
- WiFi: Corsair Vengeance RGB 3000mhz
- Motherboard: MSI Gaming X RX580
- Storage: Corsair RM550x 8GB / 240GB SSD, 1TB HDD
Have you attempted to reset the router? Is the new PC utilizing DHCP settings?
Restart your modem by unplugging it briefly and then reconnecting it.
