foxbrady, 300.0 Mbps PHY speed explains a lot. schumaku is right, that PHY rate implies 40Mhz channel width, but you should be able to do better?
On Dell PC:
- log in as admin
- computer management / device manager / network adapters
- double click on adapter / click on 'Advanced' tab
- Check these adapter properties:
- channel width for 5 GHz (want auto)
- HT mode (want VHT)
If those settings look OK, sign onto router and verify the 5GHz wireless settings: For "mode" (speed) of 5GHz -- want 'up to 1733', which is 80Mhz channe (other settings reduce channel to 40Mhz and 20 Mhz).
