Wow, a firmware update to my WRT610N router made multi-peer downloads (such as Steam updates, WoW updates, etc) about 10x faster. I always assumed it was Comcast throttling and had meant to complain. 600KB/s -> 6MB/s
The firmware update had been available for 2 years. The release notes say "Fixed Slow Internet speed issue." It didn't seem to affect single-source downloads. I feel dumb. - Tudor Bosman
I noticed that my VPN connection was getting slow during a Steam game update, and pings to the router would take 400ms on the same local network. (pings to other machines on the home network were <1ms). I was ready to ditch the router until I thought to check for a firmware update. - Tudor Bosman
