Cax80 keeps dropping internet connection
Recently purchased Nighthawk CAX80. Never had problems w/ my internet connection before hooking up the Cax80. For last 2 wks since my Cax80 has been connected, im getting disconnected like every 20 mi...
I've set up using the app while I'm on the phone with the ISP getting the CAX80 activated. Last time I activated my CM2000, I was online CHAT session with the ISP on a laptop connected to my phones internet.
Lurksalot wrote:I have a CAX80 replacment in hand and will set up later this evening using the Nighthawk app. As I recall with the first one, during setup with the app, it attempted to activate with Cox and hung there for roughly 15 - 20 minutes before I stopped it and ended up working with Cox tech support to activate. Is it recommended to activate the router with Cox prior to using the app or let the app perform this task and let it run through the process for however long it wants to take?
Please advise.
Thanks.
Hi,
The setup went fine last night. I actiivated the new CAX80 via laptop before using Nighthawk app to set up the device. I kept all default settings with the exception of 'admin' password and 5 GHz wi-fi name\password. It was working smoothly until shortly after 10 PM when wifi connections dropped to all devices. I checked the Connection Status under Advanced Home->Internet Port, the status color was orange/amber and all values were 0 (zero). I did not try to hard wire my laptop, as I needed to get to bed. In the middle of the night I checked my 802.11n and a 802.11ac devices and they were still not connected, however after 4:30 am they were connected once again and still are as of this post. This morning I took a closer look at 'Logs' and 'Event Log'. Under Event Log at 10:03 PM I see 'Resetting the cable modem due to docsDevResetNow', I have attached a screen shot.
What happened here? A web search indicates the router cable modem needs to be rebooted of which I have not done.
As of this post the CAX80 appears to be stable. I'm going continue to leave everything as is until tonight, then I'll make additional tweaks and plug-in a USB storage device.
Lost wifi connection on all devices, again.
Hard wired laptop and it had connection but could not reach router at www.routerlogin.net only with 192.168.100.1
Cable Connection page looked good
Under Advnaced Home, Internet Port was orange\amber color. For a while Connection Status, properties, i.e. IP Address, Subnet Mask, etc. values were all 0'z (zeo's). They eventually populated after about 30 to 45 minutes and Internet Port turned green.
The CAX80 is unstable at this point. I'm going to hold off on taking it back (again), as I have another 12 days for a refund. Hopefully it stabilizes.
Something just isn't right. I've done all I can as my skills are limited as a consumer. Given the price point on this device I shouldn't need to peform troubleshooting to get it to function properly, however I am willing to.
I am hesitant to work with Netgear tech support as I've not had good experience with them, but will give them another opportunity.
Thank.
Make contact with the forum moderator. Hopefully between your ISP and NG, can't help you figure this out.
Hey Lurksalot -- I've been living this same situation for a month (also Cox here). Currently on my second CAX80 and working with Netgear Support with no luck. You can see their most recent suggestions here:
I just wanted to update everyone on my saga. After 2 weeks of back and forth between my ISP and Netgear, Netgear sent a new modem that I put in place about 12 hours ago. It has gone down twice in the past 12 hours. Once we get through the workday, I'll start calling Netgear and the ISP. (We are working from home like lots of people). I'm not expecting the ISP to find anything since their gigabit modem worked flawlessly for months, but I suppose I'll have to go through the motions.
jesmith602 My second CAX80 was stable from Sunday morning to Monday afternoon. So I was very happy. As soon as I tried to tweak a setting, as suggeted in the other thread, things went bad again. I tried to enable Airtime-Fairness. I have a mix of older and new devices. I left things in a bad state overnight to see if it would self resolve, it did not. I had to reboot the device to get it back in a working state. Once again something overnight went awary and the log wasn't helpful as the same goes for the Event Log. This morning I worked with Cox to get it reprovisioned, and they said everything looked good on their end. I rebooted but it was stalled trying to get back on with Cox. I had to reset the cable modem router to get it functioning again. The past few hours it has been stable. Hopefully it stays that way. The things is I feel I can't attempt to make tweaks as needed otherwise it appears things may go bad again. I haven't even connected my USB storage device at this point, and that will require some setting mods, etc.
And I have not reached out to NG tech support.
Thanks.
As of this morning, I can not wirelessly connect any mobile devices including an Android tablet to the CAX80 other than laptops. I have an older laptop with Wi-Fi 4 (802.11n) which can also connect. I have my work laptop hard wired and is working.
Here's the log entry when attempting to connect a mobile phone wirelessly which states 'Connected, no Internet' on the device ;
[DHCP IP: 192.168.1.43] to MAC address dc:bf:e9:a4:eb:2c 1 Wed Sep 30 08:50:34 2020 192.168.1.43:0 0.0.0.0:0 Honestly I don't think this is something NG tech support can fix unless there is a firmware update for the router portion of the device, and I don't see that happening anytime soon.
I'll keep the device until I reach the end of the in store return policy which is another 6 days or so.
Thanks.
I would presume something on there line is causing this issue. Have them look at the the logs.
You can enabled WAN/LAN debug capture on the CAX under 192.168.100.1/debug.htm. I would start this and hopefully you can capture this when the modem does down again. Pass this onto NG support.
I have restarted the device and enabled logging as FURRYe38 suggested - thanks!
If NG tech support would like to assit, please feel free to contact me. I'm open to providing what is needed to assist in determining the root cause.
Attached is the current Connection Status which shows 0's \ zero values for everything, even while I write this when connected to the CAX80.
Thanks.
