Netgear C7100v Xfinity Gaming Lag

[bosskey19]

Hi, I had a question regarding my internet connection. I recently had Comcast Xfinity installed at my residence and we use the Netgear C7100V Gateway to connect to the service. We have the blast package and receive around 120 Download and 11-12 Upload speeds, with around 12-13 ms Ping to the closest servers. This is great for streaming, watching movies and YouTube, however, it hasn't been optimal for online gaming, particularly for console gaming (Xbox One).

I play Call of Duty and Sports games on the XB1 and I've noticed a weird lag/latency issue which has made the online game performance not enjoyable at all. I've gone through most of the optimizations such as port forwarding or adding the console to a DMZ, playing on a wired ethernet connection etc., but am still getting intermittent lag.

So, based on this information, and the details below, is it possible to figure out if there are any other potential underlying factors/settings that can be affecting my console's connection? Could it be the wiring of the cables? I did notice that the Xfinity Tech who came out to install my service wanted to finish up his work quickly and get out as quick as possible

Please let me know if anything else is needed and thank you so much!

Additional Details of my Gateway:

Gateway Model: Netgear C7100V

Current Firmware Version: V2.01.30

Current Settings For Xbox:  Port Forwarding & DMZ Off, UPnP On. I get an Open NAT.

your DS power levels are too high but that probably is not causing any problems. you should add a attenuator to reduce the DS and increase the US slightly. probably 6dB pad.

Have you tested it wired?

Have you tried bridge mode with just gaming PC? If the bridge mode latency is same, then it is Comcast Core network adding into delays. 

Do you have  any one running bit-torrent in home?

Hi vkdelta,

Thanks for your response! I always play on wired for the most part whenever I play the Xbox and I have not tried the bridge mode via PC just yet. Just to clarify, that is through the network connections, where I'll connect the Xbox to the PC's LAN port right? I'll test it tonight if so, and will let you know the results.

I've double checked to see if there are any torrent applications or programs running on the computers at home and can confirm that there are none running.

Thanks!

turn C7100V to bridge mode and JUST CONNECT ONLY 1 (ONE) device which is your gaming PC.

you would not be able to connect multiple devices in bridge mode. 

this is to prove pure bridge mode latency.

then once your test is done, convert it back to Gateway mode (or known as router mode), test it again.

Ideally tests are around same time to avoid peak vs non-peak differences.

also, try to do this test in off-peak for clear data.

Thank you for the clarification - I'll try it out!

Hi vkdelta,

Sorry for the very late response but wanted to provide you with an update. I tried the solution you mentioned, connecting directly to the modem on bridge mode, however, I still had the lag issues - especially on the online multiplayer gaming part (games like Call of Duty). Since then, I also tried another solution as well: Putting the C7100V in bridge mode and then using the Netgear R8000 as a router and connecting through that. Unfortunately, that produced similar results as well. Do you know what else can be causing this issue? Can it be a wiring issue or anything with the cable splitters, etc? It's really frustrating at times. 

Thanks!
