Is my internet speed maxed out?

Hi everyone, I just bought an internet plan with RCN for 110 mbps. But I've done repeated speed checks, using tools from websites online, and the fastest download speed I can get is 40 mbps (and fastest upload about 20 mbps). If I buy a more expensive plan through RCN (the next level up is 300 mbps)--is there a chance that my speed will improve to at least, say, 100 mbps? Or does that fact that... [more]

Hi everyone, I just bought an internet plan with RCN for 110 mbps. But I've done repeated speed checks, using tools from websites online, and the fastest download speed I can get is 40 mbps (and fastest upload about 20 mbps). If I buy a more expensive plan through RCN (the next level up is 300 mbps)--is there a chance that my speed will improve to at least, say, 100 mbps? Or does that fact that I've can only get about 50 mbps (at the alleged speed of 100) mean that there's something intrinsic to the cable wires in my building (which was built in 1988) that maxes out my speed at 50 mbps. Has anyone been in a similar predicament? In my building I can't really get Fios (without turning my apartment into an ugly mess of wires) so I'm stuck with TWC or RCN. I've had TWC for 7 years and have not had a good experience at all... So I'm pretty much stuck with RCN (for now). Thanks so much for any feedback. Coy [less]
