Re: Average Latency (ms) showing as a saw tooth shape
Can you post some stats. Go to 192.168.0.1 (router mode) or 192.168.100.1 (modem mode), do not log in, click on the link "Check Router Status". Copy and paste the Downstream, Upstream and Network Logs. Mask any public IP or MAC addresses.
The sample graph sows the sawtooth in the latency and not in the average latency, but I think the principle holds true, it's just one of those things. If your connection is fine I wouldn't worry about it.
