I have an SBG8300 modem/router connected to Comcast/Xfinity Cable.
I bought it from BestBuy last month, and it was working completely fine in the first few days (around 5 days). However, it periodically loses internet connection about every 2-4 days, and I have to unplug and plug back the modem each time to restore the connection. I called the ISP customer service, and they said they had updated the settings, but the same scenario kept happening afterward.
Is there any possible reason for this? The WAN status when the internet is not working is similar to the one when the internet is working.
