So, if you can, disconnect your Time Capsule from the wall Ethernet port and connect one of your gigabit capable devices directly to that port so that it picks up an address from the CGN3 and has an internet connection. I have the Hitron CGN3 with Hybrid Fibre 60/10 service. Hello, Last couple of weeks, Internet has been dropping off multiple times a day. Solved! Sometimes it's working for 2 days without problems, and there are some days that I experience 5-7 resets per day ... Don't worry about "DHCP WARNING - Non-critical field invalid in response". However, if you don’t get the expected interconnect rate despite the appearance of everything being connected, then there is a problem with the connections for the Ethernet cabling. RogersJermaine. by Error priority: critical. :). Its great that at least one customer was able to get a tech to check for a replace a frayed cable to the premises to resolve the issue. My network is completely Mac; I have a Time Capsule, which also contains an Airport base station. Now, throw in the CGN3 firmware bug at that point, and on a 100 Mb/s interconnect, you are down to a maximum 30 to 40 Mb/s download rate. Modem flapping would be an RF issue anyway. Am I correct? If you have any doubts on the house Ethernet…..read on. http://www.lowes.ca/products/compare.aspx?sku=8777782,8781121. Da ich öfters mit The cable was frayed and had water damage.

Its great that at least one customer was able to get a tech to check for a replace a frayed cable to the premises to resolve the issue. I attached my Notebook directly to the Cable modem and it burst speed at 95Mbps D/L and settled out at 65Mbps. this is mean you lost some field in dhcp server. Go to Solution. Now I finally got some useful answer from provider. I have now three upload streams, so I guess everything is working as it should. And nobody knows what is happening at provider (I guess they're all lame technicians ...), Downstream DOCSIS CM Eventlog: 7: 2020-12-11 03:29:05 74010100 notice CM-STATUS message sent. Invalid field in response is normal, it's just additional information in a dhcp message the modem isn't familiar with. Atttempting continuous pings from that location to the home system shows packet loss at varying rates. Don't worry about the occasional one. go to the connection tab and double check your power levels. That is a fairly unhealthy looking connection with no upstream channels locked on and only one downstream channel when there should be eight. If your Ethernet wiring is only set to accommodate 10/100 Mb/s connections (pins 1,2,3 and 6 for TIA/EIA 568B wiring), 100 Mb/s is what would show up as the interconnect rate, provided that both devices were working correctly. Check as well the WAN uptime and see if it has reset to 0 when this drop occurs. DHCP WARNING - Non-critical field invalid in response. Upstream : 410Mhz and US channel: 2, and when reset will happen, DS freq. The upload remained the same at 5.65Mbps. If it reads 100 Mb/s or less, you will probably see 30 to 40 Mb/s. The power levels are off which could indicate a cabling or connector issue. Error type: 82000200. If there is a wire that is not connected correctly or perhaps loose, depending on which one it is, the two devices will auto-negotiate down to some common data rate that they can both agree on. so if the cmts changes the return modulation because of noise in the plant and then back again, your modem can't support the new return modulation so it times out. So there must be problem at providers side. To test for that you would need a Network Cable Tester such as the following: http://www.lowes.ca/products/compare.aspx?sku=8777782,8781121. 2010-01-25 14:32:00 3-Critical R02.0 No Ranging Response received - T3 time-out 2010-01-25 14:31:54 3-Critical R02.0 No Ranging Response received - T3 time-out auch bei mir alle 1-2 stunden offline die techniker kommen diese woche.

Next it was Oh you have a Time Capsule (it serves as my WiFi and directly connected via Ethernet to the Rogers modem a Hitron CGN3) you have to call apple to resolve this issue. Thanks agin for your help and rather informative trouble shooting. Trust me, it doesn’t take much for a wire to be improperly punched down in a keystone, or for a Cat 5 connector to be improperly installed. could be old modem firmware as well. What do you mean by: " you lost some field in dhcp server"? I did notice downstream light went to green (no DOCSIS 3.1 anymore) last night after my last post. At -5 dB it 'should' be fine, but I've seen weirder stuff. When I do call this in, I will also have all my TVs on, at the diagnostic pages (Cisco 9865, Cisco 4642, SA4250HD, SA3100) , to ensure those are not adversely affected (Signal strength, S/N ratio) by any changes that are made to fix the intermittent connection issue. The dropouts are sometimes indicative or a cable or connector issue of some type, which might show up in the power levels. in my house, but the problem remains. - edited Looking at your speed issue I would say that the slow upload could be attributed to the single upstream channel, if that is the only channel up.
