Getting knocked offline two three times a day.
Hi,
I'm on Cox's 300 mb grandfathered plan and I'm having issues with my Arris TM3402 3.1 docsis Cable Modem. For the last week, the cable modem is getting knocked offline, sometimes two times, sometimes three times a day. Before I contact Cox support directly, I pulled some signal levels from it and the downstream signal levels look okay. The Upstream power levels are a bit low, but would that be the reason for why I'm losing internet for no reason, requiring me to manually reboot the cable modem two and three times a day. I have had more problems with my cable modem here in Las Vegas during the summer months, but I've never experienced getting kicked offline so much as I have been lately. Could someone give me some input regarding those signal levels and tell me if there's anything there that could contribute to the issues I'm experiencing.
Thanks for any help.
