Overwatch PC - Latency issue on Rain5G

[madrynn]

Hi,

I have a seemingly intermittent latency issue.

Normal ping on specifically Overwatch (PC game) is ~180ms, but at times it goes up to 260ms and then stays there.
Some times a router reboot is able to resolve the issue, but not always.
Local pings are stable at around 13ms.

Anybody have similar issues?
Any suggestions?

Thanks in advance!
