What changed?
Changed router from R7800 to Orbi RBR50v2,all other devices remain unchanged.
What happended?
- My PC (Windows 10 64bit) cannot access to internet if I choose dual band OR 5GHz in Device Manager>Network Adapters>[my network card]>Advanced>Property>802.11a/b/g wireless mode>Value (refer attachment)
- If I choose 2.4GHz 802.11b/g, I can access to internet.
Observation
- The same PC can connect to internet whilst using R7800 5GHz in the past.
- All other devices (iPhone, iPad) can connect to internet via 5GHz before and after with both routers (R7800 and Orbi)
- I tried to uninstall my network card (Intel AC 8265) and reboot, the PC install the network card automatically, but problem remain.
Great thanks for your kind assistance.
