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.
