High packet loss every time it rains. No fix so far

I'm to the point I'm ready to go to AT&T and downgrading to 50 down and 3 up just to get internet that actually works.  I'm paying 190$ a month for internet that doesn't work.  I've been with Cox for the 10 years I've been in my house.  I never had any issues.  Then August 2019 happened.  We had 100 mph winds come through.  Ever since I get 35-50% or more of packet loss every time the wind blows or it rains.  I have tech after tech after tech out to look at my equipment.  The last tech that came out said "everything is fine" well yes while he was here everything was working fine.  Unfortunately the techs cancel or I can't seem to get a tech out here when the issue is actually happening.  Right now I'm sitting at 35% packet loss.  My logs in my modem look like this.

Is there anyone out there that works for Cox that can assist me.  I am the head of IT at work.  If I hear one more technician tell me it's because I don't have a Cox branded modem/router or ask me "how many devices I have connected and if they are wired or wireless"  I'm going to lose my *** mind.  Last Chance.  I will not be paying another bill from Cox unless this is fixed.  

  • Hello. The modem is reporting a lot of t3 errors and about 4% packet loss at this time. I recommend having a tech come out to take a look. Please send us an email with your full name, address, and a link to this thread so we can help get this issue resolved for you. -Allan, Cox Support Forums Moderator.

      This would be the 5th tech to come out.  The past 4 have told me they could not find any issues and everything "is perfectly fine" and yet the next time it rains my packet drop rate skyrockets to 35-50%.  Currently it is fluctuating between 3 and 33%.  It sounds like there is a connection that is getting shorted somewhere in the line causing all the issues but it has been happening since the last week in August 2019.  How has this not been fixed?  I will send an email and request support AGAIN but honestly it has gotten to the point I have lost all faith in Cox technicians.  What email should I send the request to?
