For the last 2 months my internet has been going out randomly. Ive tried 3 different modems and 4 different routers but they dont seem to make a difference. Also I have replaced all of my Ethernet cables.
Our technicians say my signal is good.
I am currently using the motorolla surfboard SB6121.
I get this error sometimes and it failed to establish an ip. Jan 01 1970 00:05:24 3-Critical D01.0 DHCP FAILED - Discover sent, no offer received;CM-MAC=7c:bf:b1:60:6c:e8;CMTS-MAC=00:14:f1:e4:b9:92;CM-QOS=1.1;CM-VER=3.0;

Here are some of my current specs. My power level goes to -12 sometimes but im not sure if that's bad.

I am usually VERY good at fixing technical problems by myself and with a lot more work I might be able to diagnose this but. I almost to the breaking point. (and on a side note my speeds and randomly slow and I get high pings). Please Help Me!
Thank you for the reply. Im thinking it just might be my downstream power being -9 and hitting -12. Removing the splitter does bring it to -4 to -5. I have ordered new cables and splitters that should be here tomorrow. If your right on the first post props to you my friend lol. Im going to continue testing.
So I have physically replaced every piece of hardware and every cord atleast 1 time. My levels look great now but I keep getting DHCP Failed. And it loses my IP for 15+ minutes at a time and my ping will jump from 25 steady to between 150 and 500.
