Understood.
Ok, this is definitely an older 2.4ghz-only router so we don't have to worry about 5ghz issues and you are using it on the ISP it is designed for (and the firmware configured for Bell).
It kind of complicates things in that we have an older router with an older Roku2 device so hardware issues with one or the other or both may be a factor. And we have an unactivated/new Roku device. (which we cannot yet rule out may be defective).

Try the following and see if anything improves.
1. Under the router's Settings/Wireless tab, change the SSID password. (use something easy, like a name. Do not use any special characters, question marks, etc).
2. Verify under Settings/Wireless that Wireless Security Type=WPA2-PSK (AES). Make sure TKIP is nowhere enabled. Needs to be PSK (AES). This is the default setting for this router.
3. Manually assign a Wireless Channel under Settings/Wireless/General. Try 3, 4, 8, or 9 and set the Bandwidth to 20mhz. Do not use Auto for either Channel or Bandwidth.
4. Press Save. Restart the Router. After router reboots, unplug for a minute or two. Then plug back in and reboot.
5. Using the Roku2, go to Settings/System/Advanced System Setting/Network Connection Reset/Reset Connection. After the Roku2 reboots automatically during this process, see if you can now connect using this new password.
6. If you can now connect, then try Factory Resetting the new Roku Express 3930 by pressing and holding the reset button for 30+ seconds and see if that now connects. Do not factory reset the Roku2. (it may be too old to be updated and may get stuck in a loop which will render it useless).
7. If you still do not have luck with the above, go back to the router and Enable the Guest Network under Settings/Wireless. Give the Guest Network a simple name (different from your main SSID) and see if you can leave password field blank/open. If not, again use simple password. Reboot the router again after enabling the Guest Network and see if either the Roku2 or new Express 3930 can connect to this guest network.
