C7000 bridged with r7800 problems renewing isp dhcp

[Spantanswill]

Keep getting log below from the c7000 modem with t3 and t4 disconnects. Any thoughts on this? Dhcp on r7800 set to use computer mac address.
Error (4) DHCP RENEW WARNING - Field invalid in response v4 option;CM-MAC=a0:04:60:5f:2c:c8;CMTS-MAC=00:01:5c:6b:44:4b;CM-QOS=1.1;CM-VER=3.0;

Please take a screen snip of your cable connections page and your logs. 

get all the info off the connections page as this shows the upstream/downstream connection to your isp. 

[Spantanswill]

Here's what I've got.

[plemans]

and the cable connection page? 

should look similar to the one i attached. 

[Spantanswill]

Thought i got both

[plemans]

You're downstream power levels are a little on the high side and your upstream is on the low side. upstream you usually want 35dbmv and you're right there but if the signal drops, you'd be low. And you've a few errors in your signal but nothing crazy. 

Here's where I'd start.

If there's any amplifiers, attenuators, splitters in the coax line, remove them. Use it for a while and see how it runs. And then run this same screen shot again. 

[Spantanswill]

It was connected on a splitter in the past and was having the same problem but currently connected directly to the wow line that comes through the wall.

[Spantanswill]

Connected directly with latest firmware on c7000 and on r7800. So, am I just looking at hardware issue on the isp end? Numbers are still looking same

[plemans]

Is it causing issues? i re-read back through and it didn't state exactly what it was causing. 

If you're having drops, I'd have the isp check the line

[Spantanswill]

Intermittent drops. I'll call isp back ty

[dincoglu]

Any resolution? 

I am having the same problem with WOW

[FURRYe38]

Have the ISP check the signal and line quality UP to the modem. 
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Be sure to power OFF the modem for 1 minute them back ON.

Wow replaced the line from the pole to the box ( box to the modem was already new) and the problem disappeared.
