I signed up for the 100u package about a month ago and I've been having nothing but issue with the interent.
Basically the Modem loses internet at least once a day and needs to be restarted to get internet again. The rogers technician came out and replaced the modem but the problem persists.
My setup is the Rogers Modem, connected in bridge mode to my Asus AC66u router that I've had for a few years now. Only the modem needs to be restarted to reconnect, the router operates properly and I maintain local network access.
I've set the DHCP query frequency to normal mode as suggested. I've also run the Hitron in router mode and still experienced the same problem.
Rogers is sending someone out to check the lines tomorrow but I was wondering if there was anything else I should try to resolve the problem
First question, please have a look at the product sticker at the back of the modem and let me know which modem you have, CGN3, CGN3ACR, CGN3ACSMR, CGN2, DPC-3825.
2. If its a CGN3 series modem, please log into the modem and confirm which Software (firmware) version is loaded, as seen on the Status page that comes up when you log in. If you have the modem in Bridge mode with your router running, use 192.168.100.1 to log into the modem, thru your router. You don't have to rip apart your network by using that address. If you are running the modem in Gateway mode, ie as a modem and router, you can use either 192.168.0.1, or 192.168.100.1.
3. Navigate to the STATUS ...... DOCSIS EVENT page and have a look for one of the following sequences:
a. CMTS-MAC=00:17:10 which indicates that you are connected to a Casa Systems Cable Modem Termination System (CMTS), or;
b. any of the following which indicates that you are connected to a Cisco Systems CMTS.
5. CMTS-MAC=e0:2f:6d Note: there may be other Cicso MAC addresses
as well which are not on this list yet.
Please let me know if you have the CMTS-MAC=00:17:10 sequence in your DOCSIS EVENTS log. You may need to request the trial version 184.108.40.206 if you are connected to the Casa Systems CMTS, which that sequence indicates and you have a CGN3ACSMR. If that is the case, please see the following linked page and follow the @CommunityHelps link to their public page. On the right hand side is another link to "Send this user a private message" Fill out the topic line as indicated in this thread and your HFC MAC address from the Status page in the text area along with your update request. Its already addressed, so when ready, hit SEND.
If it is the case that you have a CGN3ACSMR connected to a Casa Systems CMTS, request the updated firmware version and don't swap the modem. Most likely this combination is what is causing the current problem. This is a new issue where the Casa CMTS equipment is replacing the current Cisco CMTS equipment in order to run gigabit service. Some incompatibility has come up, requiring the updated firmware version to resolve the issue.
I run an Asus RT-AC68U, so, I believe that your router should also be able to enable or disable IPV6. If you have IPV6 enabled and have any issues with address resolution or web pages that won't load, consider disabling IPV6 for a period of time until all of the network IPV6 issues are worked out.
Hope this helps.
1. It is a CGN3ACSMR.
2. So this modem has firmware 220.127.116.11, howerver the previous one had 18.104.22.168 both did the same thing.
3. I am connecting to MAC=00:17:10, will send a message for the test firmware.
4. I do have IPv6 enabled however everything on that end has been operating properly, no issues connecting to webpages.
Ok, the problem is the combination of the Casa CMTS which supports gigabit service and the CGN3ACSMR. Firmware version 22.214.171.124 will resolve that.
126.96.36.199 is the original firmware for that modem and its terrible for gaming, VOIP phones, VPNs and any other latency intolerant application or device. 188.8.131.52 resolved those issues.
As a quick check, you could navigate to the STATUS ..... DOCSIS WAN page, copy the downstream and upstream tables and paste them into a post so that I can have a quick look at them. The copy and paste process will paste in the text contents of the tables. Those are the cable signal levels. If they are ok, then you shouldn't need a tech.
|Port ID||Frequency (MHz)||Modulation||Signal strength (dBmV)||Channel ID||Signal noise ratio (dB)|
|Port ID||Frequency (MHz)||Modulation||Signal Strength (dBmV)||Channel ID||BandWidth|
|1||23700000||ATDMA - 64QAM||39.750||2||6400000|
|2||38596000||ATDMA - 64QAM||41.250||3||3200000|
|3||30596000||ATDMA - 64QAM||39.500||1||6400000|
They are a little lower than what I get at my other location but still isn't terrible.
I would say you're good. The downstream are a little low, but tightly grouped, Signal to Noise is good as are the upstream levels. The downstream ideal level is 0 dBmV, so at -3/-4, you're good.
The only thing that could happen is that there is a very fast transient on the cable, which drops the levels and then comes back up immediately. That could be water ingress into an underground cable, or maybe the wind blowing around a cracked cable running overhead to a utility pole. If that was the case, especially with an overhead cable, the tech should be able to recognize the overall condition of the cable and decide if it needs replacing or not. My bet is the Casa CMTS and CGN3ACSMR at this time.
I'll let the tech take a look at it. I think all cable in my area are underground. I had cable internet previously with distributel and didn't have any major issues like this.
Thanks for your help
The downstream signal levels and signal to noise ratios are good. The upstream is a disaster. You only have two channels instead of three, so you must be seeing slower than usual data rates, and the remaining two channels are very near the failure points. Did the third channel data not paste into the post?
Call tech support and have the CSR run a signal check. With only two channels running, the check should return an automatic failure and you should see a tech out to your home tomorrow, or as you arrange that with the CSR.
