Internet stability problems on ARRIS BGW210-700

Whenever I try and upload a file (ex. a 138mb file to Google Drive or OneDrive) the file upload starts, then after about 5 seconds, the internet stops working, and prevents anyone from accessing the internet temporarily (about 1-3 minutes).

My PC that I'm uploading from is ethernet hardwired, 

My Pixel 6 phone is connected via 5G WIFI,

Various other computers in the house are hardwired / connected to WIFI (both bands),

All of them drop connection when 1 person tries to upload anything.

I heard that this is possibly due to a firmware/software bug in the latest update (4.21.5), something that has to do with the firewall blocking any connections when a large amount of upload bandwidth is used, if I'm understanding it correctly. 

Since it sounds as though the firewall could potentially be the issue, I tried disabling every firewall setting that I could. I then restarted the machine, double-checked to make sure the firewall Status showed that all settings were Off,

  • Packet Filter = Off,
  • IP Passthrough = Off,
  • NAT Default Server = Off,
  • Firewall Advanced = Off

After making sure every firewall related setting I could find was turned Off, I tried the upload again. Still nothing. Every device loses connection for a few minutes, before access being restored upon me canceling my upload.

Here's my next thought,

Could I try to use a 3rd party router to bypass this issue?

For example, If I took any TP-Link router on Amazon and set it up with IP Passthrough, and turned off all firewall settings on the BGW210-700, could I just use the TP-Link router as my firewall, potentially bypassing this issue alltogether?

If anyone has tried this, please let me know how it went, I'm seriously considering purchasing a 3rd party router to offload the important processes onto.

Hi there, cqhudson. We understand that you are having a concern with your internet service that stops working when you are uploading anything to your cloud storage. We can look at that together. 

 

Based on your post, we see you have the general idea of what is going on, so we are going just jump right in and say that, using a 3rd party router is at your discretion. Many users like you use 3rd party routers as an enhancement to the already existing equipment in a user home. So we do not have one opinion of one way or another. It is completely up to you. 

 

However, we do support the idea of using IP Passthrough, if you do get a 3rd party router. Since you have not made up your mind yet, let's go ahead and provide the steps need to help you configure IP Passthrough. Please follow these steps: 

  1. Open a browser on a computer that is directly connected to the RG.
  2. In the address bar, enter http://192.168.1.254.
  3. Select the Firewall tab in the RG GUI page.
  4. Select IP Passthrough below the Firewall tab.
  5. Enter the Device Access Code if prompted.
  6. Select Passthrough option from the Allocation Mode drop-down menu.
  7. Select manual from the Passthrough Mode drop-down.
  8. Select Save. A re-starting gateway reminder message appears. 
  9. Select Restart Now to complete the setting change.
  10. Manually configure your device to use the WAN IP address, default gateway, and Broadband Subnet mask from your gateway.

If you have any other questions, please let us know. We are always here to help.  Thanks for posting with AT&T Community Forums.

This sounds more like buffer bloat. Are you fiber or DSL?  What is your upload speed?  When you saturate the upload direction, you will see extreme spikes in echos and most likely, the internet will appear not to work.

The solution I found was to enable traffic filtering on my router (the ATT RG cannot do it) to limit my upload traffic to about 90% of my upload speed.

@tinslwc I'm on DSL, 10MB down and I believe ~1MB upload, but I would have to verify that.

Limiting upload sounds like a good idea.

I have a new router coming in next week (Linksys EA8300) and am planning to offload all important processes into it. I will try and set up traffic filtering on the new router when it comes in.

@ATTHelp thanks for the input, I'll try following those steps once my new router comes in.

This seems to be a common theme since ATT pushed Firmware 4.21.5 to BWG210 modem at the start of February.  There's been plenty of other reports of this.  

https://forums.att.com/conversations/att-internet-equipment/broadband-stays-up-but-internet-fails-modem-shows-ping-default-gateway-in-diagnostics-as-fail-then-recovers-in-about-5-to-10-minutes/63edb8de30ffb0289557fd77?page=7

ATT, you need to address this ASAP, since you automatically pushed the firmware, and have handicapped a lot of BGW210 users.

Out of curiosity what upload and download speeds do you get from your phone on its mobile data plan/network assuming you have one?  I ask because unless you live somewhere with very poor cell reception, you should be able to beat your ADSL connection speeds assuming you do actually have AT&T's legacy ADSL.

You have an Android phone so even if you don't have tethering on your data plan or have capacity-limited tethering, you could still view and completely control your phone with a Windows or Linux computer and upload files from it after transferring them from your computer over Wi-Fi or a USB cable.  If you have an unlimited data plan for your phone, I would use it for uploads at least until this gets sorted out.

Did setting up a router with pass thru mode solve the problem?  I'm seeing the same problem and desperately need to solve it!  I'm on VDSL 25/6 and used to backup to the cloud till this problem occurred.

I don't see why it would.  The AT&T gateway's "passthrough mode" is NOT layer 2 bridging.  It is not even layer 3 routing.  From what I have read "passthrough" mode going all the way back to the 2wire gateways is nothing but TCP/UDP port and ICMP forwarding and used to be called "DMZ plus" mode.  What that means in practical terms is that the AT&T Internet connection is still restricted to the number of connections (2000 for the BGW210-700) and other limitations imposed by the AT&T gateway.  That means that if this problem is caused by a firmware bug or some other condition of the AT&T gateway, there is no getting around it without replacing the gateway with a different one.  And, AT&T does not allow that due to the 802.1X authentication requiring the certificate embedded in the gateway to connect to AT&T's network.

Thanks, that was my feeling also but I thought I would ask some of the people who have been trying to figure out the what their luck had been. I'm faced with the same issue and am looking for a solution.
