I'm troubleshooting a WiFi condition on an HP Envy laptop where the 2.4GHz band has extremely high ping rate and the 5GHz band does not. Using Google's 18.104.22.168 DNS server as a benchmark 2.4 average typical time 2800-3000ms w/ packet loss 5.0 average typical time 28-36ms -Signal strength indicator for both bands show full bars. -Drivers cleared and reinstalled. -Other devices are not having problems on 2.4GHz band. -Windows 10 fully updated. -No other wireless signals in range. -No typical sources of interference. At this point I'm starting to wonder if there might be a hardware issue. Has anyone ever confirmed one band of a dual-band WiFi card going bad? Thanks HF.
