XR500 drops internet
I am having an issue where the internet stops working..... I have 2 Xbox ones being used and they randomly disconnect and now the wifi doesn't work either. The wifi is connected but no internet. On...
The firmware has now been publicly released: https://community.netgear.com/t5/Nighthawk-Pro-Gaming-Routers/New-Firmware-for-XR500-2-3-2-32-fixes-disconnection-issue/m-p/1636839#M3864
If you are having a disconnection issue, please upgrade to this firmware (or a later one in the future). Thank you everyone for your patience
Does your cable modem have an Intel Puma 6 or 7 chipset? There are many that do. Reason for the question being I was getting the same exact symptoms as you, as discussed in Message 6 of 7 in following thread (mistitled, because it wasn't the XR500's fault). Message 6, here, was the solution for me:
Keep in mind the first image was from merely pinging the cable modem. This wreaked utter havoc on the XR500, cause packet loss and worse when pinging, say, Google.
Please note: Message is not marked as solution, because I encountered some sort of error while editing the original solution message, which somehow deleted the message; same basic post though.
Thank you for pointing this out. I do have the CM700 which has the Puma 6 chipset... The only solution is to get a new modem? I just bought this modem mid-July, so I hope there is a better solution but I read somewhere that it can't be fixed through firmware...
Clintb12 :
It's been 2 years since this issue first came to light, and the best Intel has been able to do is mitigate the issue somewhat through firmware updates (badmodems.com is a website entirely devoted to this issue, lots of info there).
The Netgear CM700 has the bad, Intel Puma chipset. The Netgear CM600 does not (Broadcom-based).
I recommend calling your ISP to find out what modems they allow (since you will have to call them to activate whatever modem you buy). My ISP (Spectrum) lists the modems they allow on their website. I bought a Netgear CM600 for $90, and it's been smooth sailing ever since.
Good luck in your search for a non-Intel-Puma-6/7-based modem. Please let me know how it turns out.
Clintb12 :
FYI, when I called Spectrum to activate the CM600, the tech on the phone and I had to wait a little between steps, so I told him about the issue. His response was, "you know, you're one of the few people to have figured that out."
I also already had a tech scheduled for a visit at the time I called. Didn't cancel the appointment, because I wanted to turn in the bad modem. When the tech arrived the next day, we chatted a bit. They're very aware of the issue, but the tech said their hands are tied. By whom I'm not sure (thinking upper-level management).
- I have the Netgear CM1000 - smooth sailing for me as well.
I can't believe they're still selling this model! You know I was going to buy the CM600 but the CM700 was on sale for the same price so I figured why not get an extra 8 DS channels for the same price? Little did I know... I just feel burned because I bought this router and modem less than 3 months ago. I'll keep you posted. I just feel lucky that you happened to see and respond to my message.
I did notice DoS attacks in my router logs. The issue with the Puma is that it makes it extra easy to take your modem offline with a DoS attack and the firmware updates disable the reset function of the modem?
I know, right. Your modem and many others are still being sold by the tens of thousands, and all these poor people like you (and me for over two years) not knowing wtf is going on. Much credit to Fraser though for pointing me in the right direction.
As for seeing your message, I'm watching this thread because there are bound to be many more until this issue is made well-known. I'm thankful too. All this time I've been wondering wtf when every so often, far too often, I would get no response upon clicking M1.
RE: DOS attacks. You'll still get those, but now that you mention it I'm getting them far less often, maybe because I got a new IP address along with the CM600 activation, and am thus no longer associated with a (obviously?) vulnerable device. Scary stuff.
