CM1000 requiring rebooting several times a day (Comcast)
I recently purchased a Netgear CM1000 for use on Comcast and several times a day the internet just stops working despite all lights still showing green. When this happens I can't even log into the w...
Interesting, the overall problem was solved for me and several neighbors. Cox replaced a mini-amplifier in the box at the street. However, I found the item that had the largest impact to overall network stability was unplugging our Ac1200's extenders. interestingly, we each had one on our individual networks and removing them resolved the overall issues.
you levels seems ok.
are you testing your speeds directly hardwired? or testing wirelessly?
what is the your speed tier subscribed for? Extreme?
Please PM me.
Adding answers here for others (sent you a PM as requested):
- I'm testing the speeds right off the router (which is wired to the modem). I back up those tests with various other devices.
- My plan should be 200/10 in my area.
Here's what I get:
However, right after a modem reboot I'll get full 200/10 or better.
Here is a test immediately following a reboot of the modem:
- Have you had ISP come out and check your lines from the pole to the modem? Comcast replaced everything from pole to modem. I now have only one splitter in the line and that is to separate TV from Modem. Power levels went up to positive range instead of neg range and it is steady now.
I am having this exact problem as well. I noticed my speeds were crawling this morning and getting 1/10 my normal internet speeds of 180Mbps. I rebooted the modem and immediately, my speeds were normal again. On v.15 firmware Comcast 150/20 internet.
I am having the exact issue! I'm going to leave a comment on Amazon in addition to emailing Xfinity that they should remove this absolutely horrible product from their recommended list. What a disgrace and poor excuse for a prodcut!!!
