I have a rpi B+ with a tp-link wn725n usb wifi dongle. I have connected to my home router, but the connections is sketchy at best. The rpi is about 6 feet line of sight from the router at the moment. I can use a browser, but it's boggingly slow. I just ran
rp-update and restarted the computer. I'm looking for advice on how to proceed diagnosing the issue.
