Ping Spikes Randomly While Gaming.

[TK_switch]

Hello,

Whenever I try to play games online, ping keeps spiking intermittently throughout the whole day averaging from 25-40 ms to 1000+ ms for a couple of seconds combined with some packet loss. It really affects my gaming experience heavily in ping-sensitive environments such as first-person shooters and fighting games; it's extremely frustrating. 

Any assistance to fix this problem would be great. 👍

Find out how much Latency & Packet Loss you have on your connection to the public internet.

What every you see in a game that is above the baseline for your internet connection is due to the distance to the game servers plus their performance and load balancing.

I ran the tests and everything seems perfect.

The problem persists with the internet overall as it affects the whole household, not just gaming when the ping spikes occur.

I opened up the routers page and it seems the Ranged Upstream Channel (Hz) has failed. Is this okay?

Hi @TK_switch,

Thank you for your posts and welcome to our community forums. We're here to help.

I'm very sorry to hear of the issues you've experienced with your connection recently. Are these ongoing today? If they are, would you mind clarifying what troubleshooting and diagnostics you've performed thus far?

Thanks,
 

[TK_switch]

Hello @Zack_R 

The issues has been ongoing for couple of months now. I have tried all these methods but nothing has improved:

• Factory resetted through pinhole.
• Rebooted the router multiple of times with no avail through UI and power socket.
• Allowed ICMP inbound through firewall.
• I tried modem mode but the connection is still the same and no improvements.
• Replaced the ethernet cables (CAT 7).

Hello,

Have the Upstream Channels reconnected  ?

There should be 4 or more DOCSIS 3.0 upstream channels.

[TK_switch]

Hello

No. The upstream provisional channel still shows as "Failed" and the four upstream channels are not available.
