New 1G Fiber install ATT upspeed <70mbps down <90mbps what is wrong here?

Just had ATT (fiber) 1G fiber installed (20190411), they put in a BGW210-700 device

This was installed because I must have higher up/down speeds. I work from home and xfinity 'blast' was failing to meet the consistency, speed (within reason) and kept dropping service mid day during week. This is not so good when you are in middle of a conf call.

 

Testing this 1G, and wow its worse am I missing something here?

Every speed test while on the 5 or 2.4 is showing (even when I am sitting right 'on' the device') speeds atrociously low (download 60-70, upload 70-80mbps). One of the forums said disable IPv6 that had no impact. Another change the auto to full duplex 1G that had no impact.

 

I tried the following test tools:

https://www.att.com/support/speedtest/

www.speedtest.net (even worse results)

https://fast.com/# (this shows at 100 up/down not more)

 

The expectation for 1000mbps fiber is reasonable to expect over 100mbps at least if not closer to 1000mbps.

What am I missing here?

 

I am not expecting exactly 1G but at least upto should be in the >300's range.

 

Help.

Looking at the back of the modem he has it plugged into the red port
(ONT). Are you saying that is hardwired to 100? should it be in the green
port (boardband)?

I subscribed explicitly to 1000mbps (1G). How to fix this? hardware side
or do I need to call tech support?

@predogma  Is the device you are speed testing from connected to a yellow port on the gateway via cat 5 cable or a wireless device? If testing wirelessly, 100 is not ideal but acceptable. If wired, check to see if your device is capable of 1 gig.  Ont should be connected to the red port. 

 

Login to your account and see if you are on the 1000 plan.  You can call cs and have them do a line check. Also soeedtest from the gateway. Gateway home page ( http://192.168.1.254/cgi-bin/broadbandstatistics.ha) diagnostics and Speedtest. Post back results.

It turns out that the fiber and this modem is controlled such that it
determines 5.0 vs 2.4 bandwidth signal dynamically. It uses only one sid.
If you configure the device 2.4 with alternate sid to distinguish from 5
(which I did) seemed to have messed it up and it got stuck just using 2.4
band for both sid. A factory/prog reset on the modem to clear that
resolved the issue.

All good now. WIFI ~500-690 which is more around range I expect with one of
my laptops (macbook pro 2019). The older devices range down around 200-300
depending on device.
