Suggested troubleshooting steps
If you suspect that your network or ISP is causing your Collaborate Ultra session issues, please try the following:
- Use a hardwired ethernet connection to your router.
- If hardwiring is not an option, and you must use WiFi, be sure that you are located as close to the router as physically possible.
- Ensure that the router is properly placed in the home for maximum efficiency.
- For example, place the router in a high spot in the center of the room, away from other electronic devices, windows, microwaves etc.

- Restart the modem and/or router.
- Reboot your computer.
- Shut down all unnecessary programs on the computer being used to access the Collaborate Ultra session, especially programs that use an internet connection such as email, instant messaging clients, streaming services (Netflix, YouTube), other web conferencing options (Skype, Webex), etc.
- Limit the number of devices and services using the network connection in the home like tablets, cell phones, smart tv's, streaming devices and streaming services (Roku, Firestick, Hulu, Netflix), gaming consoles, and other computers.
- If you purchased your router separately, call your router manufacturer for router support.
