What exactly is the problem, it's unclear what "very halting" means? If there is a hardware on/off switching for wireless devices, of course make sure that's turned on.
The driver for the intel wlan should be included with the linux kernel installed with Bodhi and from your screenshot seems to be recognized...
One way to try another driver would be to upgrade to more recent kernel, which isn't part of normal automatic updates. But if older version of Bodhi didn't have the problem you are experiencing, that may be the wrong track. But, if you are out of ideas to try, its unlikely to hurt, and you can still boot the older kernel or revert back to it permanently if it does cause new issues.
If you want to try that, paste this command, then reboot, it'll bring you up to kernel version 5.4.x
Code:
sudo apt install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04
