Hey bro, all my equipment is original TM supplied. Never touched since installed. I didn't even get notice from TM about upgrading (other than email), just suddenly realized my wifi is working, but no internet + got sms say order done. This is usually symptom of upgrading work.

Based on experience, I just off modem/router/phone/etc and just let it rest for 10 mins and turn back on. At first see internet light on BTU/router not lighted, but after like 2 mins? internet got back on, buka speed test, realized got upgraded.
