NT (Formerly CAT) Internet Woes - Anyone Else?

[Ratsima]

My condo in Cha Am gets Internet from the ISP formerly known as CAT. This is fiber optic to the condo and CAT 5 from the condo router to the units. Each unit gets one private IP address. I use an Apple AirPort Extreme to distribute IP addresses in a different subnet to my wired and wireless devices. This has been working pretty well for six or seven years. The throughput has steadily increased over the years and is now up to around 50Mbps.

Over the last week or so, the connection has become very flaky with frequent brief disconnects and very bad throughput. It appears that the connection has been completely down since about midnight last night. (I am home in Korat now so everything I know is via remote connections.) The condo claims that everything is fine with the implication that it must be my router or?

Anyone else with CAT noticed any connection or throughput problems?

I check the connection every four minutes and log the results. Here's a log fragment from yesterday:
