Been noticing my internet crapping out at random times. I've isolated the problem to my router. When plugged directly into the modem everything is fine and I get the full service I'm paying, but when plugged through the router I get bottlenecked, where previously there wasn't any bottleneck. This only started a few months ago. Not only that, the speeds shift wildly, from 10 Mbps to 50 and back again in the span of minutes. I'm a novice when it comes to networking issues, and was hoping somebody could point me in the general direction that could maybe save me a few bucks. I'm on a really tight budget, and if I can avoid paying the 30 bucks for a new router that'd be great, but so be it if the thing just turns out to be fried.

It's a belkin f9k1009v1, over 3 years old by now. I do suspect it's just done with, but I figured it was worth a post for some general advice. I'm just one guy in an apartment, so I never needed anything more than what it gave me when it worked. Thanks a bunch for any help.
