I cancelled my contract with AT&T and switched over to Cox Gigablast last year for $119 a month. After the first few months of exceeding the 1TB data cap I went ahead and upgraded to the unlimited plan ($49.99/mo) to avoid all the overcharges.
I've been having a lot of connection problems and intermittent upload/download speeds the past several months. Went to the Cox website to see if there was a fix and noticed my data usage is still high (roughly 2TB a month). Considering I really only play Xbox One and use Chromecast to watch shows on Hulu/YouTube TV (720p/1080p only), I'm a little suspicious.
I checked the event log for my Netgear CM1000 modem and noticed a bunch of errors piled up such as:
- RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW
- Dynamic Range Window violation
- TLV-11 - unrecognized OID;
I'll add the event log and cable connection info below, if someone could take a look and help me make sense of all this I'd greatly appreciate it.
