I ran 1.70 for a LONG time. Stable and fast. I upgraded to 1.80, and still just fine.
The EdgeRouter Pro is connected to the standard issue AT&T Uverse router, which is acting fine. My Internet connection normally yields ~22M down and ~1.75M up...solid as a rock, as tested over 3+ years.
I recently upgraded to 1.85, and over the course of the day, my Internet connection will slow to a crawl. I run a test on SpeedTest.net and other similar sites, and I'm getting a variance between 4M and 8M down, and if I reboot the router, it's immediately back up to the 22M/1.75M that I'm used to. Then, over a few hours, it wil slow down again, requiring me to reboot the router again. I switched to 1.90, and it's still having this problem.
Has anyone seen this type of behavior? Any ideas on what could cause something like this?
