Seems many of us are having issues with the cgn3..I have to reboot it daily. My speeds are less so used with my rtn66u then my cgn2 was. So basically im paying more for slower speeds and less reliabilty.i have of oucrse been on the phone with rogers to log my issues every single time it goes out
I have a low tolerence for this type of thing but having each occurence logged will help shortly 🙂
Yesterday, the Rogers on-site technician supervisor I have been dealing with for the past couple of weeks confirmed that Rogers is looking into problems and numerous customer complaints with the CGN3 "at a high level" - e.g. he participated in a conf call with a few directors.
If you are experiencing issues with the CGN3, it may be wise to consider another more stable gateway in the mean time.
Here is the latest post on my experience with the CGN3 from another thread.
I was recently forced to upgrade my gateway in order to get my full bandwidth cap (yes, I know it's not hardware related! tell them that!)
I use a vpn to connect to my office and often (but not all the time), when I disconnect the VPN, my DNS screws up.
This didn't happen with the old gateway.
I've found the solution is to run "ipconfig /flushdns" and then it comes back again. Might work for your situation too maybe.
I have the exact story word for word of original poster. Have been rebooting my modem on a daily basis to resolve this DNS issue right after going to bridge mode on the recommendation of a tech. Is there a solution to this? If I go back to the old modem will I still get the close to 200mbps speeds I currently get? My NIC is already set with the 8.8. DNS IPs and still the router needs to be rebooted every morning.
This appears to be the same issue discussed inm the "Keep needing to reboot CGN3" thread. Rogers has admitted that this is a problem and they are (hopefully) working to fix it.
Some people (me included) find that the problem goes away or is much less frequent when you go back to gateway mode from bridge mode. But the web UI is very flaky and prone to crashing the device when you try to use it.
You should still be able to get the Ultimate 150/10 service working fine with other routers like the Cisco and perhaps SMC, but for the Ultimate 250/20 service it seems that this is the only modem that you can use, although some at Rogers have a different view.
