Unable to connect after power outage
So to my knowledge, we had just recently had a brief thunderstorm last night while I was at work. When I returned home our wifi was out and did not return after multiple reboots. This morning I had done extensive searching to try and troubleshoot the issue, with multiple power cycles to our Netgear CM1000 modem and our Tp-Link Archer AX21 router. I have even tried to factory reset both the modem and router to no resolve of the issue. For now, the indicator lights on the modem are all static green for power, downstream, upstream and internet. No lights will turn on for the ethernet despite multiple different cables connected securely. The lights will however blink orange once during reboot. For the router only the power button is solid green, with the occasional rest of the lights flashing green except for the internet flashing orange. I have also done troubleshooting with Spectrum to which they stated there is no issue with the ISP and that it may be a router/modem issue.Intermittent connection problems
I am looking for help diagnosing intermittent connectivity issues with my CM1000 modem. I am not sure what clues I should be looking for and I have not been able to detect any patterns to indicate cause. Let me offer some details… I am an Xfinity customer in my home, and I have been using a Netgear CM1000 modem for around 6 months. Everything worked great for the first 5 months. However, the last month I have been getting hit with maddening intermittent connection problems. I lose all internet connectivity and cannot ping anything on the internet for short periods of time. These issues usually just last a minute or two, but sometimes as long as 5 minutes. Network connectivity eventually comes back without any intervention from me. Some days I have no connectivity issues, other days it happens several times (usually in the most in-opportune times!). I have not noticed any change in the modem lights when this occurs. When I call Xfinity/Comcast support their only suggestion is to reboot the modem. That usually causes the connection to be restored, but I don’t think that is really fixing anything – like I said the connection issues usually only last a minute or two anyways. The agent I talked to at Comcast said she cannot see anything else on her end. Since I own my own modem, she stated it will likely cost me money to have a tech come out and look at it. Before I break down and have someone come out, I wanted to search for some evidence that is or is not a modem problem. I’m not against buying a new modem either, but am going to be frustrated if I have the same problems. This behavior occurs on multiple computers - both wireless and wired – which leads me to believe it is a network issue. I swapped out my router for a few days just to see if it was possibly a router issue. The same issues occurred with the replacement router, so I think I can rule that out as well. I did chat with my good friend Google a bit and learned to check the power levels. The power levels seem ok as they fall between the -7 to 7 range for downstream and 38-48 for upstream. I haven’t touched any cables lately, but did double check the cables I had access to to make sure they were connected tightly. My Hardware version is 2.02 and firmware version is V3.01.04. I understand that Xfinifity/Comcast controls pushing out the firmware updates so there is not much I can really do about adjusting firmware. I do have an older (slower) modem I suppose I could go back to for a while and see if I have problems with that. Any thoughts/ideas would be appreciated.
Not getting correct speed with Comcast
Hello all In November I saw that Comcast offered a higher tier internet service in my neighborhood. Speeds are advertised up to 986 Mbps. Since I signed up I’ve only seen 350-400 Mbps. I had a couple of online chats and phone calls with Comcast. I also had two techs come to the house to check the signal to the house. The second tech said that Comcast had to approve new firmware for my CM1000 modem (this was in December). He said that once Comcast approved the firmware then Netgear would push the upgrade to my modem directly. I called to try to get credit for billing since I wasn’t getting the correct speeds and I was forced to chat with Comcast tech support again. The tech sent me a link to the Nighthawk X6 router firmware page to update my CM1000 cable modem :| When I told them it was the wrong equipment they told me to contact Netgear directly to receive my firmware update. I sent this link to him. https://www.netgear.com/support/product/CM1000#download It says “Current Versions Firmware upgrades are pushed down by your ISP. For more information, please see our Knowledge Base .” He just told me to talk to Netgear :| Has anyone had any success getting advertised speeds with Comcast Gigabit Internet? Thanks for your timeCM1000 + Orbi (RBK50) on Xfinity - Constant Disconnects
Hello there, I am having similar problems to ones on this board - Constant disconnects on the Orbi platform with a CM1000 modem on Xfinity. A Comcast tech has been by, checked the levels and left saying everything's fine with the incoming line. It works great when it does ( Blast tier - ~200 - 250 Mbps) but the disconnects are getting out of hand. They last a few seconds at a time to ~6 minutes at a time (most common) if left unattended - Rebooting the modem/router fixes it in a minute and a half (even that's not consistent of late). Details: CM1000 Hardware Version 2.02 Firmware Version V3.01.04 Orbi RBK50 Router Firmware Version V2.1.1.16 uPnP OFF,Daisy Chaining Disabled, MU-MIMO and Implicit Beamforming Enabled, Fast Roaming Disabled I am attaching logs and event logs from the modem and router if at all it helps nailing the problem(s). Please let me know what else I can do before returning either/both modem and router.
