Re: Comcast Enterprise Fiber Slow Connection Problem from TW Telecom

With a max bandwidth of 25 Mbps and a 40ms RTT, the max is more like 14MB/s or 1.75 Mbps. https://www.switch.ch/network/tools/tcp_throughput/index.html?mss=1460rtt=80loss=1e-06bw=25rtt2=35win=64Calculate=Calculate But that's only if either endpoint is stuck at a 64 KB receive window. A quick

Re: Belkin Router issues this morning?

Sounds like it might have been a DNS issue of some sort. The end result was that the customer routers couldn't reach their heartbeat server, which made them think they weren't on the net. The routers would then be helpful and redirect all customer port 80 traffic to the router's configuration page
