I have a moderately good router running OpenWRT and if it couldn't handle my speeds I would've noticed it.
I can push files from a notebook connected via wi-fi to my PC at nearly 100MB/s (cable connecting PC and router is the bottleneck), and people on the openwrt forums say it can handle up to about 120MB/s, at which point the hardware acceleration in its network card seems to be at its limit. The DSL hardware is separate, but it can go all the way to VDSL whereas I only got ADSL2+.
My ISP seems to be in a mix of overloading the copper cabling and just being plain incompetent.
