AT&T U-verse BGW210-700 modem/router issue
Can you pls fix this problem? In early May'19, I was given a new modem/router BGW210-700 when a technician came to fix some other issue that AT&T had caused with my U-verse internet. Ever since, my internet experience has been really bad, with intermittent slowness (almost stalled internet) and the downstream bitrate never reaching near (within 80-90%) the service max (18mbps - this is what we get in the mountains for a reasonable price). Downstream is most often in the range of 1-8mbps when the router is not stalled. Streaming movies/videos never works smoothly anymore. Now, before I was given this router, everything worked just fine with the prior equipment (I do not recall the manufacturer, but reading through numerous other related posts, I am guessing it was PACE).
I have been through countless factory resets, reboots etc. When I called AT&T for service, they sent another technician and he swapped the router with another BGW210-700 unit. That did not help either. The FW version on the unit was 1.8.18, and as of today it is 1.9.16. When I run the diagnostics test in the router setup page, the test does not always complete, and the speed test in the router setup page shows either "test did not complete" or when it finishes it shows downstream bitrate of about 16mbps. However any internet test (whether it's ATT Speedtest or Oocla etc.) running on any connected devices always shows something between 1-8mbps if the test completes. Average latency is upwards of 600ms.
I have the usual type and number of devices hooked up to this router (eg: 3 Ring Cameras, Nest, Computer, Tablet, SmartTV etc.). And all those worked fine before. So the devices connected to the router or the traffic generated by them are not a source of the problem. They are the same as what was connected to the prior modem/router which always worked.
My request: Pls send me a modem/router that works. Internet experience has been really bad for the last 6 weeks.
Any advice from the other forum users is welcome.
