I have a PC that doesnt have a wifi card, and I tried to install it but failed miserably, and I have been using since then a TP- Link usb wifi extender. However, the connections has slowly degraded up to almost being unusable. Im talking 10-16 hours to download a couple gigabytes. Is there any way to have rapid wifi connection without having to get a 30 meter cable across my house? I can provide further information about my PC if needed. Thanks!

So a couple of years ago one of my friends helped me and homebrewed my 2ds, and installed a couple of cool games on it, but now I wanna fullyreset it and mod it myself with games I like now. How can I do that? Thanks
