I've recently started seeing a variance in packet loss on my Xbox One over the past 2 weeks and I'm trying to figure out the cause. My ISP is Comcast XFinity and I'm on the 105mbps/10mbps plan. I have an Arris SB6183 Modem hooked up to my Netgear Nighthawk R7000 (AC1900). My Xbox is hardwired. As far as my speeds go, everything tests ok. Both on this site and on my Xbox One. My NAT type on the Xbox is OPEN. The Detailed Network Statistics on my Xbox One shows Download speeds of 118mbps Down and 11mbps Up. The Latency shows 65ms (which is good). The MTU Size is 1480, which is fine as well. The issue is when I take a look at the packet loss, which shows I'm getting either 1 or 2% packet loss. Now, I've tried using both Cat5 and Cat6 ethernet cables and it makes no difference. I've also tried connecting my Xbox through WiFi but the packet loss is still there. I've ran an ethernet cable straight from my Arris SB6183 modem to the Xbox, same thing. I've even tried using the gateway Comcast provides to see if my modem was the issue but to no avail. The packet loss remains. Next, I took in my Xbox One to Best Buy and swapped it for an Xbox One Elite through the 2 year protection plan I had on it, thinking that my Xbox might be the culprit. I get home, excited to use my new Elite controller and convinced that I was finally in the clear...BAMMM the Xbox Network tests hit me in the face with a 1% packet loss yet again!
I've tried port forwarding, tried changing the MTU Size, giving the Xbox One a static IP address, putting the Xbox in DMZ Mode, turning on UPNP, turning off UPNP, turning on QoS, turning off QoS, etc but the packet loss never clears. As I mentioned before, this began happening about 2 weeks ago. I started noticing a big difference in online gameplay on my Xbox One so i ran the Network tests. That's when I first noticed that I was getting that 1% packet loss. Before that, I'd have 0% packet loss every time. Yesterday I brought my Xbox over to a friends house to test it with his connection and guess what I saw? Yep, you guessed it 0% packet loss! So it's definitely an issue with my connection and nothing to do with my Xbox itself.
If anybody has knowledge or tips they wouldn't mind sharing with me, I'd really appreciate it. Also, if anyone knows the best method or the best site for testing packet loss please let me know. I wish I had the option of going with Verizon FiOs or Google Fiber but they don't cover my side of the Houston area. Thanks for reading and thanks for the feedback ladies and gents! Have an awesome day
