Almost 5 times a day seems a bit much to tolerate ... I have a similar issue where I lose internet connectivity (PureFibre Gigabit Internet) about every other day ... sometimes perhaps once daily (I suspect my WAN IP is being 'punted' by some TELUS node algorithm because I have unlimited data on my plan, make almost 24/7 streaming use of it, and, I'm on a residential street, so, I may be impacting overall bandwidth on my fibre network segment ... bandwidth is not supposed to be an issue for fibre per TELUS marketing, however, I can't otherwise rationalize what's happening with my service) ... while not a long term solution, I have found that rebooting my TELUS / Arcadyan modem / router gets me a new WAN IP from TELUS' upstream network and restores internet connectivity. Once you're familiar with the process, you can do it from a smartphone on Wi-Fi (from bed!) and the loss of service amounts to only about 10-15 seconds.
If you don't know how to do this reboot procedure or what model of TELUS h/w you have, unplugging your TELUS modem / router from AC power for at least 10 seconds should accomplish the same end.
I have had the same issue since switching to the new digital boxes after our move. Have had to spend hours on the phone trying to reset everything, and still have the same issues. Keep getting an error message that says we are not connected, yet Tell us shows all is good. Ready to switch to a different provider.
