      Hello, I have spectrum cable, getting 235mb down speed when I connect lan cable from the cable modem directly to my laptop.
      When I use a pfsense router, on a new netgate 3100, I only get only 20mb on a speed test.
      What things can I check? I have a netgate 3100 router. it always gets a wan ip that starts with 65.30.x

      when i connect upa different pfsense router on dell hardware I always get a WAN IP that starts with 76.x.x.x measured speed 40mb down.

      Any help Appriciated!

          ok thanks good info, I fixed the issue, after I connected the lan from the netgate to my pc I eas getting the full 230Mb, so the netgate router was not the issue. so next I removed all the other lan cables from my switch and moved the lan cable back to the switch and now im all good. Looks like I had a lan switch issue. :)
