Wireless Adapter Issues

So I originally bought a Netgear N150 a year or two back and it has always worked out for the box with any GNU/Linux Distribution until a few months ago.  After a kernel upgrade my connection became very inconsistent, I always received very low speeds (>1mbps), and constant time outs and packet loss.  I figured it was issues with the driver so I went ahead and installed ndiswrapper and installed the Windows drivers but the issue still persisted.  At this point I became a little frustrated and checked to see if the issue was still there while using it on my brothers Windows machine but it was fine.  I tried it on my laptop that runs Arch and still had the same issues as my desktop.  So I went ahead and booted into a Ubuntu LiveCD and it worked flawlessly.   I had spent about a week desperately trying different said solutions and searching but never came up with anything.

So I figured why not just a buy another since the N150 was pretty well obsolete so I bought the Asus N13(Not a big upgrade) since it got a lot of attention for working flawlessly on GNU/Linux.  Tried it out but still had the same issue.  Used ndiswrapper and tried all different Windows drivers that came with it, did everything I tried with the N150 but only had the same issue.  Works on Ubuntu and Windows but not with Arch, I also tried Crunchbang but still had the same issue.   I know this isn't an issue with the USB ports or hardware because I ran a Ubuntu LiveCD and both worked flawlessly.  Anybody have any ideas?

Here is what I get with dmesg

Re: Wireless Adapter Issues

OP here again.  I guess this an issue with a lot of people as of the kernel update a month or two ago.  I think I might roll back my kernel or just use a Ubuntu live CD, since it is the only Linux Distro it seems to work flawlessly on, until this gets fixed.  Feel kind of pathetic because I'm pretty sure this goes against the Arch Way but I have things to get done and I think a month of trying to get this to work is enough effort.  Anyhow I will be checking in regularly on this thread to see if anybody has any ideas because I can already tell I'm going to miss pacman and the AUR like crazy!

Re: Wireless Adapter Issues

Maybe you have some power saving enabled on usb port?
