Is all I see in my routers logs, Is this relevant? I'll try check right after I experience the spikes as well tonight.

The Tomato logs look unremarkable. The DHCP/DNSMASQ messages are LAN-related. As I suspected, you appear to have no *disconnections*. You may have problems on the LAN or on the Net beyond your ISP.

Your router free space is plenty.

If you use QoS you may want to keep an eye on connections for a while: QoS>View Graphs
Or else take a look at connections here:

Advanced>NF/Conntrack

If you see >1000 connections, chances are that connection spikes are crashing your router. But that doesn't seem to be the case, since you've had no router crashes. So it could be other LAN problems or distant Internet routing problems.

The important thing is that you don't appear to have "Near-end Internet" problems, i.e. problems that have to do with your ISP.

The modem log does not show a "disconnect" problem, and neither does the Router log. The Router log is much too detailed to be readable. I suggest logging everything except Cron, Scheduler, NTP. Skip the "Marks". Reduce the clutter so that you can see important messages better.

If you are worried about packet loss, use ping or maybe traceroute to see what is going on.

It seems to me that whatever "90% packet loss" you are experiencing is a consequence of what you are doing, rather than an underlying network problem that won't let you do it.

If your game tells you you have high packet loss. stop the game completely. Then use ping to measure packet loss on the network.

If your game server says "packet loss", you want to ask whether it is near you, near it, or in between.

Ping your WAN gateway to measure packet loss over your cable link. Or you can ping your ISP. Or a central site. Preferably from your router.

Be aware that network routers may not respond to pings or traceroutes, especially when there is congestion.

Please run traceroute -In 4.2.2.1
