I have been having this really odd issue where connecting my wifi to 5Ghz wifi succeeds but then trying to ping or resolve an address (e.g. google.ca) will result in a “Host not found” error message. To get the connection to work I end up:
Set Network Manager to not connect to any wifi.
Then Connect to the 2.4 Ghz radio on the same card to the router (this always connects and gets internet access).
After I make sure I can go to an internet website or ping and address I will then connected using the 5 Ghz radio. I may have to switch between the radios till it eventually works. Sometimes rebooting the system and then the 5Ghz radio and network configuration allow and address to be resolved.
IPV6 is disabled, IPV4 looks like this:
- Both radios work 100% of the time if I use Windows 10.
- I want the “Intel Centrino Advanced-N 6205 [Taylor Peak]” to work dependably. Both my Thinkpads (x230 and T430s) use the same model of radio and have the same problem. Is this a known bug. Is there a fix?
