Alright, so this past week or so it has a been a nightly occurrence for my internet to disconnect randomly throughout the night. Sometimes I will stay connected 45 minutes then it will time out for maybe 4 minutes and then it will work again. I've tried resetting my router and modem, and I've tried multiple computers on my network and they are all not getting internet. The computers are connect via ethernet, and during the times when the internet doesn't work I can still access the router and modem. I have Cox cable in Omaha, NE with a Netgear WPN824v2 router.



I noticed a lot of errors in my logs for my modem today. Here they are:

Also, here are the signal rates and stuff for my modem:

[AlucardHS]

-14 DBmV, your signal is looking weak. Should be between -7 to 7 with 0 being best. Call them !

my $0.02

Anyone know anything about all those logs errors for my modem? I noticed that every time my internet dies it lists a "critical error" for that exact time. I looked on Cox's website to try and e-mail support my logs, but their website gives me an error when I click their "E-mail us" link.  Starting to get bitter.

[Conuck]

I have been getting logs like that since I've had a cable modem. They used to freak me out but I don't worry about them ant more. I've had cable over three years now.

So its really a score sheet then? 

[pakocat]

Is the modem a Motorola sb4100?

[PeePs]

Nope, its a SB5100

[Conuck]

Its an,  ARRIS DOCSIS 1.1 / PacketCable 1.0 Touchstone Telephony Modem HW_REV: 02

I got the the same think when I had a RCA 425.

[PeePs]

Could it be possible that my modem has gone bad, or do you thing all this is because the signal is so weak? Hopefully I'll have time to call them sometime this weekend.

[pakocat]

It seems a lot of folks out there are having the same exact problems. Many forums on this subject. No fixes though. I was playing Star Wars II on my playstation last night and kept getting the lost connection signal and I've also noticed some problems with my X-Box 360 wireless connections recently as well. I'm hard wired into a Linksys wireless router from a Motorola sb4100 using Time Warner RR as an ISP. I also receive Digital Phone service through the same connection. That means its utilizing signals in both directions ... I wonder if there is some type of interference going on in the transfer of signals somehow? Anyway I'm told that the ISP doesn't update the DOCSIS firmware and Linksys network wizard finds no problems with my connection. Maybe if I switch to a static IP address ..... or register the MAC address with the ISP .... or switch to a DSL ...... arghhhh ... sigh 

[crazy_ate]

I have a solution to this problem.

I had exactly the same problem.  Just popped up out of the blue a few weeks back -- my internet connection would go down about every 20 minutes, some times more frequently, somethimes less.  A sample of my error log is below:

2008-07-02 12:22:45 3-Critical 0x040D9A2C DHCP WARNING - Non-critical field invalid in response.
2008-07-02 12:22:42 3-Critical 0x040D9964 DHCP FAILED - Discover sent, no offer received

2008-07-02 12:21:41 3-Critical 0x04E33A74 Started Unicast Maintenance Ranging - No Response received - T3 time-out
2008-07-02 12:18:21 3-Critical 0x040D9A2C DHCP WARNING - Non-critical field invalid in response.

After much thought I did three things:

[1]  I loosened and retightened all my F connectors.  At the drop outside and at the two way splitter that takes one leg to the cable modem and the other leg to my 4-way amplified splitter for my TV's.

Result = NG

[2]  Next I made up a new RU6 cable to run from the modem to the splitter thinking the old cable might be shot.

Result = NG

[3]  I REPLACED THE TWO WAY SPLITTER

Result = NO MORE PROBLEMS

Apparently these little puupies can and do go bad.  In addition, I have seen where cable techs recommend not using gold plated splitters -- my old one was gold plated made by GE.

Problem solved and no a single friggin' error in the past 48 hours.  Incidentally my modem is a 2002 SB5100 and my service is Optimum Online in Morris County NJ.  Also running through an AT&T VOIP ATA and a Linksys wireless router.

[PeePs]

Alright, thanks a lot for the information. I'll see if I can try a new splitter this weekend and I'll post the results after I do!
