Issue : Redmi note 5 Pro : No internet in desktop while wifi tethering
If you are using a Redmi Note 5 Pro and while tethering to a desktop PC i noticed that there was no internet on the Desktop. While the internet was working just fine on Phone.
The workout for this issue was changing the APN settings. I changed the APN protocol from IPv6/ Ipv4 to just IPv4 and the same change in APN roaming Protocol also.
After that reconnect and my internet on the Desktop PC started working fine.
