Unable to connect Blink Sync Module 2 to RAXE500 WiFi router

I had contacted Blink support prior to submitting this post. Blink support finally responded last night to me and the first time had me repeat the steps I mentioned I had already done (also mentioned in this post). Their second response they had me do a firmware reset which corrected the issue. This firmware reset included these steps:
- Reboot the Wifi router
- Relocate the Sync module next to the Wifi router
- Unplug the sync module and wait for 30 seconds.
- While unplugged, using a paperclip or similar item, press and hold the reset button on the sync module.
- Then plug it into power.
- Continue holding the reset button until you see a flashing red light. Once you see the flashing red, you can release the button.

After this, I was able to add the sync module successfully. I'm sure that steps 1 and 2 probably weren't needed, did them anyway.

I hope this is helpful to the next person having this issue. Do note that the [TKIP] security method is required to be added which is not a default on this router.
