After discussing with our Technology team, we can offer you some suggestions as there are so many variables for connectivity issues. You may also have family or neighbors who can help you out.

If wireless, reboot your wireless router and/or check for updates. 

Have you tried to join your meeting from outside your home where the wireless signal may be stronger? (coffee shop, church/ office)? 

Use a wired network connection for a more stable connection. Your Internet Provider could matter and may be able to suggest a booster for your router.

Have you tried to join from a mobile phone? Depending on your data plan, your mobile may be an option either directly or as a tethered hotspot.

We are praying that you will be able to connect to your meeting without issues.
