Re: [PLUG] Internet access in Berwyn slows to a crawl as the day wears on ...

After a couple of anxious days pinging, speedtest-cli-ing, and traceroute-ing, 
the culprit seems to be my router. For what reason ? That escapes me ...

Typical ping result:


PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=2.02 ms
64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=3.11 ms
64 bytes from 192.168.1.1: icmp_seq=3 ttl=64 time=1.85 ms


Alarming ping result:


PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=197 ms
64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=20.3 ms
64 bytes from 192.168.1.1: icmp_seq=3 ttl=64 time=2.78 ms


Scary ping result:


PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=456 ms
64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=296 ms
64 bytes from 192.168.1.1: icmp_seq=3 ttl=64 time=173 ms

The last and slowest traceroute result was at 7:30 AM EDT today, while my Internet 
access was undiminished and my missus was still getting up.
I'm getting upload speeds from 10 Mbits/s down to 0.5 Mbits/s and download speeds from 8 Mbits/s down to 4 Mbits/s ... the Verizon chatperson suggested that I reboot my router, which I did before I started all this testing. It took a couple of reboots before I could get back on, but my Internet access has been adequate in spite of the fifteen-fold reduction in speed, which loss I attribute to my use of the ClamAV software. Why that should be so extreme I do not know, but I have been living with 
ClamAV for several years without worrying about it.
The 0.5 Mbits/s upload speed was just after 8:00 AM EDT on Thursday, right about the time business customers would be most active ... or their automated servers ... I was never in a business that was trying to accomplish anything that early though.
The present question is: What is slowing down the router ? I've checked the router's setup page, and I don't see any identities other than our two set-top boxes and two laptops. Our FIOS interface is inside our house (driveway is too long for a cable) 
so we're the only users of that interface.

Best regards,
George Langford
