I'm aware there are quite a few threads out there discussing wireless connectivity issues, and I can assure you I've read them. But I'm still having problems after following through all of those.

My problem is this. My wifi is slow to the point of not working, and drops connection every few minutes. What's more strange than that is that, when I speedtest, I get these weird spikes in speed, up and down, up and down.

I've tried the things listed here, here, and here. None of these have resolved the issue.

I'm aware you guys are going to need wireless card info and stuff, but I'm not sure the exact commands to run/stuff to give you, so please let me know that and I'll update the question with any pertinent info.

Thanks for your time, this has been driving me nuts for days now. I should mention that the connection is fine when I'm: using wired connection, using windows, using another computer in the house. However, the problem persists at my university as well, so I'm pretty sure it isn't just my router.

Using the info in the 3rd link seems an odd choice when you don't even know how to find out what wireless adapter you have. It's specific to an atheros model, which he doesn't even specify in the article. Be careful what you find in web searches. You may get a better answer if you post a question in ubuntuforums, maybe not. That's where I've gone for wireless problems. Anyway, enter this in terminal ... sudo lshw -C network ... and post the output. That's a start. –  user138156 Mar 23 at 14:29
    
What you posted is ethernet, not wireless. –  chili555 Mar 23 at 15:58
