I've been experiencing very bad ping spikes for the past 2 months.It's is not noticeable while doing web surfing or loading videos, but it is extremely annoying in Games. I even switched to a better internet plan & replaced my modem but it does not fix the problem, could this be a problem with the cable?
I recorded this video using Teamspeak's ping as an example because games' ping are simlar. I used to have constant 40 - 60 ms ping before this happened (>100ms ping in Teamspeak can be about 200 - 500 ms ping in games).
These are download speed tests (all done within 1 hour):
Yep, those are the correct tables. The signal levels and signal to noise ratios don't look bad at all. Can you rerun your speedtests via wired connection, just to see the difference between wired and wireless ping times. Its interesting to see a 4 channel down modem these days, what modem are you running out of curiosity? Is this a Rogers combo modem / router or a modem with a third party router running?
