Thanks for the tip but already checked the SNR and its fine.  the log is full of "acquiring IP address" entries. It has improved this evening and I am streaming Netflix fine for the past hour as well as Hulu. I noticed I am over their data limit by 100 Gb...data usage reports 1.12 TB but that is incorrect.  I am consistently around 500-600 Gb per month and haven't done anything differently.  Personally, I think they do not like it when one cancels the TV service and switches to Amazon Fire TV and use Hulu for live tv. I was simply sick of paying 240 per month with 70 dollars in fees so I dropped everything except internet for 64.00 with fees plus 50 for Hulu live tv along with an endless library of movies and tv for free.  Anyway, I looked at a website that shows outages and problems broken down by providers and the greater Boston area is listed as having major issues for the past three days and as of 9 pm problems began dropping and as of 1 AM, the area is no longer flagged in red, just showing about 80 reported issues by end-users on that site.  Comcast claims "unlimited data" and you must look hard to find the disclosure regarding the 1 TB limit. I am going to call the FTC in the morning asking that they change their advertising to reflect the cap.

O/k the speeds have nothing to do with the data limit. It is suspended due to COVID 19 anyway. Something else is going on. Good luck with it !
