BGW320 Slow Flashing Red Light Fix Explanation

I found a dozen 'BGW slow blinking red light' threads here on AT&T forums and on reddit plus half a dozen articles on the issue as well and read the router information on the light indicator. They all say basically the same thing;

"Blinking Red (Slow) Your Wi-Fi Gateway does not have a broadband connection. Please check for a loose, disconnected, or damaged cable, and reset your router"

So, check for physical damage of the hardware. Then, either unplug the power cable for 30 seconds then plugging it back in, holding the red reset button, or unplugged the power from the outlet for 30 seconds then plug back in. If this doesn't work then you require a technician to come out. Most of the threads had a technician come out. Some threads have technicians respond expanding on the issue, they state something is preventing the light from properly passing through the cable in two of these threads I read. The consensus is always however that there is something hardware related that is the problem, either in the house, or outside of the house, and it is not on AT&T's end in which they can simply do something from you calling and getting it sorted over the phone.

Here is my issue. Once is nothing, twice is a coincidence, but three times is a pattern. Three times now I got the slow flashing red light on the front of my BGW320. Three times I went through the Smart Home Manager diagnostics that failed, verified there was no outages, and reset the router exactly as instructed. Three times I scheduled for a technician to come out. Three times I had to cancel the schedule as in roughly 5-6 hours of this, everything works perfectly once more with no intervention from myself after scheduling and no technician coming out and doing anything. The weather has been clear, temperatures are not freezing, and winds are low. No one on our property messing with cables 12+ feet in the air on the outside at 3am. They are not back-to-back either, the last time it happened was roughly 5 months ago, no issues since. No new cables or equipment nor moving the cables or router since the first time it happened also. Everything is a year and a half old.

I need someone to please explain to me this phenomenon. If this is 100% hardware related that required intervention and is not on AT&T's end, how does doing nothing 3 times lead to it fixing itself? The other threads I read several concluded with a technician coming out and fixing something either in the house or outside it or people without internet for days while they wait, complaining calling tech support on the phone doesn't help and they are stuck until the technician comes out days later. But in my case, same router(BGW320), same light indicator as them, same insistence by app and online that I need some sort of physical intervention to fix the issue, but it resolves itself in a matter of hours. How?

Could be a coincidence too, this latest time, this morning, and I believe at least the last time from what I can remember, everything started working again about the time AT&T service hours started around 8am. On the app it states everything was good on their end though, they couldn't connect to the gateway for any troubleshooting, but once people show up to work things just magically work. Seems weird. I would love to know why.

We'd be glad to help you resolve your gateway trouble, joshbull623.


Because this is a recurring issue, we recommend allowing a technician to come out and determine what's causing this, if it happens again.


There are different things that could be contributing to gateway losing its Broadband connection -- it's possible that something outside your home is causing this. It would be a good idea to have a technician take a look.


If you have any other questions or would like to schedule a service call, let us know.
