Speed Test
xfinity says use their speed test but it's all over the place. Like why would you test speed from puma Arizona to New Mexico? It's not accurate I don't think. If my pc is pinging off Arizona or whatever then maybe something needs fixing. Maybe once again xfinity can't handle the traffic from so many

If any of you have noticed that the speed test to your gateway no longer works, check you firewall security settings. If it is set to High, test will fail. If you switch to Medium security tests work.

Speed test
There is discrepancy when testing speeds. Using xfinity test or Oakla I get 30-35 maps consistently. Using Mlab I get 190-200 mbs which is supossibly what I am paying for. Verizon gives me the same as Mlab, and if use fast.com I get 80-90 mbps. A 10 to 15 percent is perhaps expected but 6 times lowe

Test speed to gateway was removed
Why was the option to test the speed to your gateway removed? It feels like Xfinity is trying to hide the tools used by power users to manage their own network. There is another post by a different user a few months ago with the same observation and a copy paste from the FAQ's was posted in response

What speeds should my speed test from Xfinity app be showing?
I am getting about 30% of my plan speed when running the speed test from the Xfinity mobile app. I have gigabit Ethernet and a tech just came out to my house and told me these speeds are “average”. If that’s the case why am I paying for 1300?

Speed test shows very low speeds
I have the gig of internet. At least that's how it was sold to me. I run a speed test, it shows I have 49 upload speed and 49 download speed. I haven't even used said internet much due to it being near unusable. Let me know of a solution or I will cancel
