I agree that's a piece of junk but also that's not RCA DCM 425.

That's RCA DCM 305.

RCA DCM 425 looks like THIS.
I know, but I never SAID I had an RCA DCM 425. ;)

You are still going to have to deal with mediacom, since your pings to the 10.20.65.1 hop are WAY to high. The average time should be under 35ms, which shows mediacom has a problem somewhere on your node. Are the ping times still high at 9pm? What are they like at 7am? As for the upstream power level getting up to 60, that's another problem, to many splitters, poor cable (including the drop from the pole or pedestal)
ADDED: If it's mediacoms modem, have them swap it out, no sense buying one.]]> http://www.dslreports.com/forum/remark,20933450 Mon, 11 Aug 2008 12:50:32 EDT Re: [IL] Appt connection drop help (assuming bad cable modem) http://www.dslreports.com/forum/remark,20933266 WhatHappened : Go with the RCA DCM 425.

Update:

Had a tech come to the Appt complex..fooled around with the router only and then said the connection is "fine". Got in touch with landlord again to see if he can get another FST to visit the complex and look at the cable modem only and look at signal noise. As before, packet loss at the 2nd hop and not connecting beyond it remains the issue.

I've also noticed that now the Upstream power level will hit 61.1 dBmV and take down the connection as well...

If the FST still deems that there is no problems on the line, what are my options..I'm just tired of reading emails for 10-20 min then loosing connection for 20..then back again for 5..on / off /on / off and it's making me lose my sanity.

The smaller version works great but for some odd reason the bigger version started having problems. I have so far replaced over a dozen of them.

The same thing every time, reported down SNR is around 28-29 even though with a new modem it's just fine.

Also I would try without the router when troubleshooting.]]> http://www.dslreports.com/forum/remark,20585804 Tue, 03 Jun 2008 18:55:45 EDT Re: [IL] Appt connection drop help (assuming bad cable modem) http://www.dslreports.com/forum/remark,20583420 Turbocpe :

My connection to the wireless router in the appt is solid (using landline), but it's the hop beyond it that's been giving me issues since I've moved here last august. I originally thought it was just people on the network using up too much bandwith just making my life hell, but I figured that couldn't be right... after investigating further, I found that the router will lose connection to the DHCP, and to solve this problem for a short amount of time, I have to restart the router to regain a connection. I don't think the problem is with the router, but rather with the cable modem that's inside the appt. this piece of hardware on the event log shows A LOT of errors. Connection to this piece of hardware just to view it settings is also not always available (will give Page can't be displayed error??)

2. Give a description of any home networking setup you may have. (i.e. router make/ model, hubs, adapters, etc.)
I live in an appt here in downtown, shared with all other tenants in the building.
Router is a Wzr2-G3000z router. This router was installed in September to replace an older linksys router in the appt. Running firmware V. 1.00_1.26

3. Modem make, model and firmware version.
Ambit 60678 EU cable modem
Hardware Version: 1.12
Software Version: 2.57.2033

4. Signal levels found at »192.168.100.1 if applicable.
Downstream Receive Power Level: -3.3 dBmV
Downstream SNR: 29.3 dB
Upstream Transmit Power Level: 43.0 dBmV

My question is: is this problem from that cable modem, and do I contact my landlord about this issue and have them handle it, or go straight to mediacom for tech support? I just want to make sure that when I do need to contact tech support, I am doing everything possible to troubleshoot from my end, to not waste anyone's time. My PC I take to work with me, and the connection there is stable and normal.
