This worked and wifi was working fine I had proper connection. But today after reboot the same issues are back again and ant-sel doesn't seem to be working. Wifi works fine in windows 10. How do I get wifi to work properly?

Wifi issues with RTL8723BE in linux mint.
I installed linux mint a couple days ago and was having issues with wifi connectivity. The wifi signal was very slow and wifi connection kept dropping. So, I tried this solution I found on the forums by JeremyB

Re: Wifi issues with RTL8723BE in linux mint.
I would use the grub menu at boot advanced options menu to boot into a kernel older than 4.15.0-33 for now
Re: Wifi issues with RTL8723BE in linux mint.
Hi there. Not at all sure if it's appropriate to post here, but I am having a very similar issue with RTL8723BE on this HP Laptop. Network Manager shows the wireless device, but does not find any available networks. Airplane Mode / F12 key disables and enables the device. Tried updating everything, EVERYTHING including kernel, etc. Formatted and reinstalled 18.3 Sylvia. Wanting to try fixes in their proper order this time. Thanks in advance!

Re: Wifi issues with RTL8723BE in linux mint.

Network Manager shows the wireless device, but does not find any available networks. Airplane Mode / F12 key disables and enables the device. Tried updating everything, EVERYTHING including kernel, etc. Formatted and reinstalled 18.3 Sylvia. Wanting to try fixes in their proper order this time. Thanks in advance!
