SB6141 timeout issues - Time Warner Internet

#1
This question is about "SB6141 timeout issues", with Time Warner Cable internet and apps. Hi All,

Looks like I get to join the large population of people experiencing timeout issues on TWCs network.

Timeouts happen sporadically throughout the day, this issue just started yesterday and I either lose connection or router reboots due to T4 timeout exception. This mainly gets triggered while watching netflix or remoting into my work VPN.

Firmware
B_KOMODO-1.0.6.16-SCM00-NOSH
Log is peppered with:
-
[TABLE]

No Ranging Response received - T3 time-out;CM-MAC=b0:77:ac:2c:b3:ba;CMTS-MAC=00:17:10:88:98:85;CM-QOS=1.1;CM-VER=3.0;

and the t4 error but my log already went past that error with alot of T3 errors.

I am in NYC (murray hill area) any suggestions would be appreciated!
