Hitron CGN3ACSMR modem wifi works but LAN doesn't.
Went to turn on my comp yesterday and found that i had no internet. Wifi works fine (both 2.4 and 5.0). The LAN LED at the front of the router is off and none of the lights on the back next to the LAN ports are on either. Tried unplugging it a couple of times but no luck.
I remember reading about LAN issues with earlier versions of the firmware. Try requesting the latest if you don't have it.
You may need to do a factory reset.
see Datalink's post at the end of this thread re LAN ports issue : http://communityforums.rogers.com/t5/forums/forumtopicpage/board-id/Getting_connected/thread-id/3341...
it looks like firmware versions 21 and up solve the LAN port problem
Rogers has been switching over to new hardware which is causing the LAN port problems. The new firmware is compatible with said hardware apparently. See Datalink's earlier post in the thread regarding switching from Cisco CMTS to Casa CMTS.
So I've started noticing this issue on Saturday night. All the ethernet connected device will stop working, but WiFi is fine. The ports on the modem are constantly blinking orange too. A reboot of the modem fixes the issue.
This usually happens once or so every ~24 hours. Any idea what the problem could be? Would a factory reset help? Or maybe I need to replace the modem?
@illiterate can you log into the modem and confirm what Software (firmware) version is currently loaded, as indicated on the Status page. My guess would be 18.104.22.168 or older. V22.214.171.124 I believe is the current network wide version for that modem. .20 and above resolved that situation from what I remember.
While you are logged into the modem, can you navigate to the DOCSIS WAN page, copy the downstream and upstream tables and paste them into a post. That will paste in the text contents of the tables. It might be worth having a look at the signal levels just to see where they currently are.
Looks like it's running the latest firmware.
|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||41.000||2||6400000|
|2||38596000||ATDMA - 64QAM||42.250||3||3200000|
|3||30596000||ATDMA - 64QAM||41.000||1||6400000|
Your signal levels look fine. How many devices do you have plugged into the ports? The amber LED indicates that the modem port is connected to a gigabit device and that the modem and device is communicating at a 1 Gb/s rate. Thats a port to port rate, not the internet data rate that you would have for your internet plan. A green LED indicates that the modem port is running at 10/100 Mb/s with the connected device. Again, thats a port to port communication rate.
As of now, only one active device - my desktop PC. The other two devices that are connected via ethernet are usually powered off 90% of the time.
hmm, ok, very strange. Does the pc connect directly to the modem via Cat 5e or Cat 6 or does the pc connect to a surge arrester and then to the modem via ethernet?
Fwiw, we have seen rare instances in the past where there was a problem with a device port. Replace the port on the device by using an ethernet card and the problem was resolved.
Have you tried a cable swap yet or different port on the modem?
You might just have a modem that has a failing ethernet controller. First step would be to run a factory reset. If that doesn't work, swap the modem. That will tell you pretty quickly if the modem was at fault. If that still doesn't work, then there is a port problem on a device. Any chance of a strange sleep setting on the pc within the power saving settings?
