Cable modem getting stuck on upstream ranging in Cable users http://www.dslreports.com/forum/r20905148 en Wed, 11 Nov 2009 02:41:17 EDT Wed, 11 Nov 2009 02:41:17 EDT Re: Cable modem getting stuck on upstream ranging http://www.dslreports.com/forum/remark,20915648 xlimitx : The only thing I could think of with regards to "the channels are all full" would be that some providers setup their CMTSs to do admission control on the return path. This might make the the CMTS block the modem from coming online.

That's pretty rare though from my understanding.]]> http://www.dslreports.com/forum/remark,20915648 Thu, 07 Aug 2008 17:16:56 EDT Re: Cable modem getting stuck on upstream ranging http://www.dslreports.com/forum/remark,20911050 defiant : It's more likely your modem is experiencing return-path issues due to some kind of wiring or plant issue. ]]> http://www.dslreports.com/forum/remark,20911050 Wed, 06 Aug 2008 21:17:58 EDT Re: Cable modem getting stuck on upstream ranging http://www.dslreports.com/forum/remark,20910440 heels_fan : I do not understand this part

One reason for getting the upstream channel problem is that the channels are all full. I would guess either because they are really full or a hardware failure is limiting the channels available.

Armstrong Cable Rising Sun, MD area. The problem is that the modem gets stuck at the upstream ranging. We would be using the system and all of a sudden loose internet. I would pull up the modem's web page and it would be sitting at the upstream ranging. If I looked at the modem it would have 1st and second light solid and send would be blinking. The system would basically be locked up. If I try and put the modem in standby it would not reply or try and reboot the modem through the web interface it would not respond. I would give it a couple minutes to several minutes sometimes start pulling the power and then one of the times it would reboot and it would finally fully initialize. The big problem is that I called Armstrong on Tues last week after the modem started going down constantly this was 2 days after a violent thunder storm with sideways rain and finally was down more than up. Before this it was going down like once or twice a day mostly in between 10pm and 10:30pm for about the last 2-3 weeks. They responded and it was down when they came we tried a power reboot to no effect so they replaced the modem and the new modem came right up. Fast forward to Friday and it starts going up and down again. I call Armstrong they setup for a Monday afternoon appointment. we go through the weekend not a problem, tech comes on Monday system is up and no problems. He does nothing and leaves. 10 minutes later the problem is happening. it fixes itself again after about 5 minutes of down time. Now it is Tuesday and it has happened again. Going through my own troubleshooting I am finding that the modem when getting stuck on upstream ranging it is able to communicate and the system is up but the system can't get an upstream channel. Any thoughts on this. This is hit and miss with getting Armstrong out. One reason for getting the upstream channel problem is that the channels are all full. I would guess either because they are really full or a hardware failure is limiting the channels available. Any thoughts ?]]> http://www.dslreports.com/forum/remark,20905148 Tue, 05 Aug 2008 20:49:45 EDT
