Running into ECONNRESET error on claude code

I've been using claude code for years without any issues. I recently moved and got Xfinity and a netgear nighhawk router with it (modem + router) but idk why, I keep running into this issue, constantly throws the ECONNRESET error. When i hit send after entering the prompt, 80% of the time, it hangs and throws an API error after that; sometimes it works, sometimes it doesn't, making CC absolutely unusable. Router is CAX80 if it makes a difference; I've tried changing settings and disabling DoS, etc but it didn't help. TIA!
