This problem is hugely frustrating, I'll avoid the rant about stupid roommates bullshit.
Basically my ISP recently changed, everything else is the same, just the ISP and the associated modem/router and stuff. The speed used to be fine, now it's largely unworkable and just painfully slow.
I mean I tend to get annoyed when images and youtube videos load extremely slowly, or when my phone gets better speed than my desktop. Sometimes pages are slow or give me trouble, it's most frustrating, and I can pretty much conclude at this point any sort of game which requires an internet connection is going to be entirely unplayable. It's definitely the connection and not the machine, since local stuff works fine.
I looked at an AT&T speed test which just confirmed everything I knew without offering me any new information that would be helpful to me.
The question is: What can I do about it and what's likely to work? I've gone through some of the usual basic steps to try to fix it, reloading the page, quitting the browser, restarting the PC and the router/modem, but it hasn't helped a bit. I'm not uncomfortable dropping $70 on router/modem from best buy if I know it will fix the problem, but I naturally don't like to spend money on junk that doesn't work. Even a cord would be fine with me, if I knew one of the sufficient length would resolve the problem.
I just don't know what I can do about it.
