Just went through the chat nightmare. The tech support agent openly acknowledged the issue but insisted that they couldn't attempt to resolve it until they sent a technician to "check my signal". So now I have a technician scheduled. What a waste of their resources and my time. I'll probably take a downgrade to the Hitron modem if they provide a reasonable credit for the hassle and downgraded equipment.
The firmware issue isn't Shaw's fault, but their customer service relating to this issue is garbage.
After a suggestion from Shaw support, I ran an ipconfig /all command and discovered that the first connection it listed was a Hyper-V Virtual Switch. After some Googling I discovered that his is a "sandbox" feature installed in Win 10 2004. Since I didn't need this, I removed it from my windows system (Control Panel). I then re-tried sleeping and waking the computer several times, and now the long internet connection delay has appeared to go away. Also, the time between ipconfig /release and ipconfig /renew is similarly shorter.
So, at least for me, this appears to have been the problem with the internet connection delay after sleep.
@bmoliver -- I then re-tried sleeping and waking the computer several times
Such a sleep/wake cycle probably did not help. It certainly will reduce the electrical power consumed during the "nap", but after waking, it just resumes where the sleep was initiated.
I recommend a full "shutdown/restart" of Windows, to restart Windows, now that you have removed that software.
It's also possible that Shaw "pushed" a software update to the cable-modem, when you were not watching.
I believe the removal of the Windows Sandbox did require a re-boot, but I have also re-booted several times since then and the internet connection delay after sleep has definitely gone away. I try to sleep the computer overnight.
Shaw technical support said no firmware updates had been pushed and that I already had the latest firmware before I did all this.
Thank you for your continued patience. I have good news that this issue is resolved in our latest firmware update: 4.6p9s1 which was issued out last night.
If you do not have the most recent firmware:
Thank you very much for alerting the group to the update. Now my system connects right away from both a restart and sleep.
Thanks for that note. Indeed, mine is now showing the new firmware even though I did not reboot the modem. Re-connecting to the internet this morning after the computer was asleep overnight had no appreciable delay. So, perhaps the old firmware was interacting with the Windows Sandbox as part of the issue with the internet delay?
Thanks Tony, seems to be working great, I've restarted computer a bunch of times and I don't loose connection.
