Internet down in NWArkansas, told "it's your modem" by tech support
Yes, it could be the modem... I mean, I've had the thing for seven years or so now, but before sending your paying subscribers out to spend $80 on a modem in the middle of a snowstorm during a danger...
Internet back down as sun sets and temps drop, and, once again, I'm told my modem is at fault, not the Frankenstein patchwork of frozen cable splices between my demarcation point and Cox's distibution hub. At least the tech is checking with the regional service office, which is under the same 4 to 6 inches of snow and freezing temps we've gotten here in NW Arkansas since Friday.
Sorry to hear about your Internet issues. My Internet is working fine, but I can relate to your weather. We got the same storm here in NE Oklahoma before it hit you in NW Arkansas. As of 9:00 am this morning, temperatures have been below freezing for 200 consecutive hours and counting. The temperature was -6 F (six below) when I bought groceries this morning at 6:00 am (safest grocery shopping time due to COVID). I think I may have been the only customer in Walmart. It's like living in an episode of "Life Below Zero"... in Oklahoma. There's a brand new river crossing the street near my house. When I called to report the water line break (not my water line), the lady just laughed, said "Get in line" and transferred me to the water department. She wasn't kidding about getting in line. I was on hold for a while due to the unusually high call volume. Now really wouldn't be a good time to work for the water line maintenance department. Anyway, good luck with your Internet and keep warm and safe.
